“La Conceria” è una realtà editoriale che da oltre un secolo,
L’impiego di nanoparticelle per applicazioni in ambito conciario è stato a più riprese sperimentato, in tempi recenti, per lo sviluppo di prodotti in cuoio con proprietà migliorative; tra le applicazioni più promettenti, sono state nello specifico individuate, anche nell’ambito di pregressi studi della Stazione Sperimentale, tecnologie per la dispesone di nano-agenti nella rifinizione, per il conferimento delle proprietà desiderate, come aumentata conducibilità elettrica superficiale (Florio et al., 2020), proprietà antimicrobiche, antiossidanti, autopulenti, ecc. negli ultimi anni, tale filone di ricerca promosso dalla SSIP, insieme al suo partenariato, ha avuto un nuovo impulso, grazie alle attività condotte nell’ambito del Progetto SINAPSI.
Avviato a valere sul Fondo per la Crescita Sostenibile – Sportello “Fabbrica intelligente” PON I&C 2014-2020, di cui al D.M. 5 marzo 2018 Capo III” (bando ex-MISE), il Progetto di ricerca e sviluppo Automation, eco-sustainability and circularity for the manufacturing of nanofunctionalized leathers (SINAPSI SIstemi evoluti e NAnotecnologie per la fabbricazione di Pelli Sostenibili ed Innovative), della durata complessiva di 36 mesi e si è positivamente concluso, con il conseguimento di risultati promettenti e potenzialmente in gradi di concorrere allo sviluppo tecnologico di settore.
Tra gli scopi primari del Progetto, lo sviluppo di nuove famiglie di pelli, per automotive, calzature e pelletteria, mediante approcci innovativi, sia in relazione ai processi produttivi impiegati, con particolare riferimento all’impiego di sistemi di concia esenti da cromo, e all’impiego di adeguati sistemi di automazione e controllo, sia in relazione all’individuazione di nanotecnologie per la funzionalizzazione ed il miglioramento delle prestazioni di prodotto. Il Progetto ha inoltre portato allo sviluppo di strategie mirate per la valorizzazione degli scarti di produzione, con soluzioni che includono un loro reimpiego in rifinizione.
Nella sfida, sono state coinvolte due importanti imprese, rappresentative dei settori di riferimento presi in considerazione, come le Concerie DMD SpA (Capofila) e LEVI Italia srl, che hanno lavorato in sinergia, attraverso il coordinamento scientifico della SSIP, in qualità di Organismo di Ricerca Partner di Progetto; sono inoltre stati coinvolti ASSOMAC, il Centro Ricerche Fiat, il Centro di Ricerca Interdipartimentale NANO_MATES dell’Università degli Studi di Salerno.
Nell’ambito di tale progetto, che ha prodotto numerosi risultati scientifici e tecnologici relativi all’impiego di tecnologie abilitanti per promuovere l’innovazione sostenibile e circolare dei prodotti in cuoio, sono state svolte attività, in collaborazione con NANO_MATES – Research Centre for Nanomaterials and Nanotechnology dell’Università degli Studi di Salerno, che hanno portato allo sviluppo di una nanoparticella multi-funzionale, in grado di conferire al cuoio simultaneamente più proprietà.
Lo studio, che ha portato al rilascio di un brevetto nazionale (Particella multifunzionale comprendente biossido di titanio, argento, diossido di silicio” – numero 102022000026556 – data di deposito 22 dicembre 2022 – data di rilascio 06 dicembre 2024) ad una domanda di brevetto internazionale, nonché ad una pubblicazione sulla rivista Scientific Reports – Nature portfolio (Fierro F., et al., 2024), ha riguardato, nello specifico, la sintesi di nanoparticelle multifunzionali “flower-like”, da utilizzare nella rifinizione della pelle, in grado di conferire simultaneamente e sinergicamente al materiale attività antimicrobica, autopulente, resistenza alla luce, proprietà idrofobiche, meccaniche, termiche e fluorescenti.
Tali nanoparticelle (NPs), sono state realizzate partendo da NPs di Ag, TiO2 e SiO2; tali nanoparticelle, vanno a formare una struttura “a forma di fiore” in cui il “pistillo” è formato da NPs di TiO2 ed i “petali” che lo circondano da nanoparticelle di argento e silice, le cui dimensioni sono dell’ordine di dieci nanometri. Le NPs multifunzionali “flower-like” sono state caratterizzate sia dal punto di vista chimico-fisico che morfologico-dimensionale, attraverso diverse tecniche, tra cui: Diffrazione di raggi X (XRD); Microscopia Elettronica a Trasmissione (TEM); Microscopia Elettronica a Scansione (SEM), accoppiata una sonda per spettroscopia a raggi X a dispersione di energia (EDS); Nanoparticles Tracking Analysis (NTA); Termogravimentria (TG-DTG); Spettroscopia Infrarossa FT-IR.
L’analisi TEM ha evidenziato la formazione di nanoparticelle somiglianti morfologicamente a “fiori” di dimensione uniforme (circa 65–70 nm di diametro), con nucleo di TiO2 (“pistillo”) circondato da “petali”, di dimensioni più piccole, costituiti da NPs di silice e di argento (Figura 1).
Fig.1: immagine al TEM delle nanoparticelle flower-like
La sintesi delle nanoparticelle flower-like è avvenuta in diverse fasi: in primo luogo, le nanoparticelle di titania sono state prodotte mediante precipitazione chimica; queste sono state poi aggiunte alla sintesi di nanoparticelle d’argento, eseguita mediante il metodo della decomposizione termica e, infine, le nanoparticelle ottenute sono state introdotte nel processo di sintesi di nanoparticelle di silice, eseguita mediante un metodo di micro-emulsione. Molecole fluorescenti di natura organica sono state incorporate alle nanoparticelle di silice. Le sintesi sono state effettuate in reattori riscaldati, con capacità di circa 5 L, per una produzione di 2–4 g/giorno, sufficienti a soddisfare le esigenze delle linee di produzione della pelle.
Il processo è stato ottimizzato per ottenere nanoparticelle multifunzionali ad elevata capacità di dispersione e stabilità in ambienti idrofili, al fine di poterle impiegare in associazione ai prodotti chimici di rifinizione comunemente impiegati; particolarmente, nanoparticelle flower-like preparate a diverse concentrazioni (mg/mL), sono state diverse disperse in prodotti chimici di rifinizione a base poliuretanica e miscelati grazie all’utilizzo di una punta ad ultrasuoni.
Successivamente gli i prodotti di rifinizione additivati di nanoparticelle flower-like sono stati applicati sulla pelle mediante spruzzatura in cabine di verniciatura industriali, per l’ottenimento di pelli multi-funzionalizzate, le cui prestazioni sono state caratterizzate per valutare l’efficacia di ciascuna proprietà conferita.
I risultati ottenuti hanno evidenziato non solo le migliorate caratteristiche attese, ma anche comportamenti migliorativi rispetto alle proprietà conferite singolarmente da ciascuna nanoparticella, precedentemente testate, con complessivo potenziamento/amplificazione di tali proprietà attribuite agli effetti sinergici scaturiti dalle etero-giunzioni tra specie diverse.
Le caratteristiche di valore aggiunto testate hanno riguardato l’attività antimicrobica verso i principali microrganismi in grado di proliferare sulla superficie dei cui (sia batteri che muffe), proprietà autopulenti, aumentata idrorepellenza, caratteristiche di fluorescenza ed aumentata resistenza meccanica, particolarmente in riferimento alla aumentata resistenza all’abrasione, a fronte della diminuzione dello spessore della rifinizione, con evidenti ricadute anche sul piano merceologico e di impatto ambientale, in relazione all’impiego minimizzato di prodotti chimici.

F/190200/02/X44 (“Sinapsi – SIstemi evoluti e Nanotecnologie per la fabbricazione di pelli Sostenibili ed Innovative), Co-financed by the Italian Ministry of Enterprises and Made in Italy (ex-MISE), Fondo per la Crescita Sostenibile- Sportello “Fabbrica intelligente”, PON I&C 2014-202 – D.M. 5 marzo 2018.
Nell’ambito di una proficua collaborazione con l’Istituto Tecnico Tecnologico “Galilei” di Arzignano, la SSIP ha lanciato una nuova iniziativa formativa destinata agli studenti delle classi quinte degli indirizzi ambientale, conciario e sanitario.
Questa iniziativa, parte integrante della “SSIP MENTORING INITIATIVE”, si propone di avvicinare i futuri tecnici e ricercatori del settore conciario a una delle tecniche analitiche più avanzate e utilizzate nel settore: la spettroscopia FT-IR.
Perché la spettroscopia FT-IR? La spettroscopia FT-IR, con un focus particolare sui film plastici e sulle rifinizioni per il cuoio, si rivela uno strumento indispensabile per un’analisi qualitativa rapida e precisa di materiali quali la pelle. La sua versatilità la rende adatta a molteplici applicazioni, dalla ricerca e sviluppo al controllo qualità, fino ad arrivare al settore forense.
Un percorso formativo completo Attraverso una serie di incontri tecnici tenuti dal dr. Francesco de Laurentiis, Tecnologo R&S della SSIP, in lingua inglese, gli studenti hanno avuto l’opportunità di approfondire i principi teorici della spettroscopia FT-IR e di applicarli a casi studio concreti.
I benefici dell’iniziativa Questa iniziativa rappresenta un investimento importante nel futuro del settore conciario, offrendo ai giovani studenti:
Un futuro promettente
La SSIP, in collaborazione con l’ITTE Galilei, conferma il proprio impegno nel sostenere la crescita e lo sviluppo del settore chimico conciario, investendo nella formazione delle nuove generazioni. Questa iniziativa rappresenta un passo avanti significativo verso un futuro sempre più innovativo e sostenibile per l’industria conciaria italiana.
ABANA PROJECTS
The global fashion system, in addition to experiencing a moment of deep economic crisis, is undergoing a complex reanalysis, driven by stringent sustainable strategies.
In this context, the design and production approach of the ‘Made in Naples’ sartorial tradition, characterised by slow times, top-quality raw materials and excellent manufacturing, becomes avant-garde compared to the models that are gradually taking shape in the panacea of fashion. This is because the Neapolitan textile and clothing industry – which the glove sector belongs to – was born and has historically evolved according to an ‘institutional system’ model by Yuniya Kawamura. This model entails a creative and productive system detached from the vision of a single designer and connected to the collective activities of a group of people who live in a given area, and commit to the production and perpetuation of a culture or ideology. Seen from this perspective, Neapolitan sartorial productions can be defined as indigenous and profoundly linked to a certain modus operandi that has never adhered to the incessant logic of the fashion system.
Far away from the inordinate succession of collections, which from the 1970s – with prêt-à-porter – to the 2000s – with the cumbersome arrival of fast fashion – have witnessed an incremental and uninterrupted rise, Neapolitan sartorial practices are back in vogue, thanks to their innate aptitude for imagining and realising great classics and outstanding timeless products. Products made over time, so ‘dense’ that they transcend the fleeting nature of fashion collections.
Naples has produced and continues to produce timeless must-have garments that remain faithful to precise sartorial standards, so much so that they have not undergone major stylistic changes. Impervious to the influences of fashions that have little shaped the style of the sartorial sector, and the Neapolitan glove in particular, famous for its lightness, for the way it adapts to the hand’s morphology, and its durability, perfect cuts and seams.
Starting from such a solid tradition, with the students of the Academy of Fine Arts of Naples, we imagined new product types that could expand the glove’s product range, by aligning it with the needs of post-contemporary consumers.
The students analysed multiple contexts of product use, hybridising them with different fields and triggering those creative short-circuits that stimulate the experimentation of innovative products. From gloves for the visually impaired to anti-stress gloves. From the balaclava glove to a motivational garment. From the glove designed to celebrate handwriting to the glove that emphasises the emotional bonds between people, all the projects developed have a specific function.
And they were created, once again, not to satisfy a trend but rather the need of new generations who prefer genderless models that do not conform to traditional labels, with unisex cuts and neutral colour patterns. Products suitable for all identities, ethnicities and physical diversity.
The projects on display are just an input to stimulate new generations of designers, so that they can intercept design measures capable of enhancing the sector. To this end, the role of the Academy of Fine Arts of Naples becomes crucial, in its capacity to train young people on new ways to learn the value of craftsmanship, and injecting it into creative-driven businesses – what the British government defines as businesses with the potential to create wealth and jobs by drawing on their intellectual property.
SOULHIDE
The Soulhide project was born out of the desire to go beyond mere functionality and create a narrative object: a glove that, apart from being worn, also tells a story.
Soulhide is a relational glove that speaks to the heart, symbolises connection and complicity and prompts users to rediscover the pleasure of walking together: a walk with your grandparents, an intimate moment with your partner or a chat with a close friend.
The gloves connect to each other through clips, placed in strategic points, which act as sensory bridges between those who wear them.
The experience they offer is truly beyond mere physical contact, and very emotional, with a touch that becomes a gesture, a presence that becomes dialogue. Each shared step is accompanied by a glove that protects and creates bonds, making invisible connections tangible.
The product is designed to be sold in sets of four gloves, consisting of two pairs.
Soulhide is not just a collection of gloves, but a real experience, an encounter between craftsmanship and emotions that restores a form of connection to be lived entirely, adding a new perspective to human contact.

MANUS SCRIPTA
“Tien a penn comm a nu guant’ ma senz’ stregner”.
This old Neapolitan saying, which translates into ‘Hold the pen like a glove, but without squeezing it’, refers to the gentleness and awareness of the art of writing.
So much more than a mechanical act, writing is a moment of thinking and reflection, an intimate bond between mind, hand and word.
In an age dominated by speed and haste, Manus Scripta helps us to rediscover the art of writing, like a Neapolitan glove from the past that invites us to rethink the depth of this ancient gesture. The project celebrates a return to writing as a conscious and intimate act.
Manus Scripta is not a simple accessory, it is a writing companion that reminds us of the elegance of movement and respect for each word, with a hand that welcomes and guides the gesture, instead of squeezing it out.
Exceeding the barriers of a simple object, this white glove symbolizes the rebirth of two traditions: handwriting and Neapolitan gloves. The soft yet durable leather hugs the hand, allowing the mind to focus on the importance of what is being written, rather than on movement.
Manus Scripta is a double act of rebirth for the Neapolitan glove, with its elegance and functionality, and for writing in its more traditional forms. Manus Scripta celebrates all this, in a project that takes us back to the sacredness of the gesture, the depth of written word and the pleasure of a timeless art form.

GLOVOLVE
In today’s scenario, where challenges are daily and psychological pressure affects young people more and more, this project focuses on a symbolic product, meant as an evolutionary medium for the person wearing it.
The name Glovolve originates from the fusion of ‘glove’ and ‘evolve’, and symbolizes an internal evolution. Every time the glove is worn, this ritual evokes ancient boxers’ bandages, which were applied under boxing gloves to protect their hands, and also to mentally prepare for the challenge.
Just like these bandages, Glovolve becomes a gesture of concentration, a symbolic act marking the passage from a condition of uncertainty to one of determination.
Wearing Glovolve is so much more than a physical gesture, it is an invitation to enter a state of awareness and strength. The glove-wearing ritual becomes a way to take care of ourselves, to focus our energy and channel it towards overcoming our daily struggles. The collection is characterised by a series of motivational phrases users can choose to embroider or print inside the bandages, to recall any intimate and personal goals they wish to achieve.
Glovolve is more than a product, it is an act of resistance, a declaration of intention. It is a new kind of object, not limited to a mere function, which becomes part of a personal narrative of strength, resilience and transformation. Each time the glove is worn, we take a step towards a stronger version of ourselves, ready to face each challenge with a new perspective, a new energy.
In this way, Glovolve responds to the profound need of protection and evolution we all have. Not just facing life, transforming it.

OBOLO A PARTENOPE (AN OBOL TO PARTHENOPE)
The hopes, joys, gratitude, faith, but also the dramas, mourning and suffering are encapsulated in art works that sum up exactly the soul of Neapolitan people: votive niches.
Far from being just small architectural structures, they are true icons of Neapolitan ‘street culture’, symbols of a neglected artistic heritage increasingly abandoned to decay. The Obolo a Partenope project was born with the intention of paying homage to the culture of Campania’s capital city, whilst also denouncing the state of semi-abandonment hundreds of votive niches in the historic city centre are in.
The Obolo a Partenope streetwear-style black leather gloves feature a minimalistic and contemporary design, with embroidered patches on the back depicting symbols taken from votive shrines in the Spanish quarters.
The glove, with clips on the back, can be continuously modified with a big collection of patches to change its meaning and look. Multiple faces of the same product lengthen its life cycle, regenerate its image by going outside the logic of collections, and creating a more sustainable product.

GLOVACLAVA
Glovaclava is a leather glove created by combining a glove and a balaclava. Its versatile design features open forefinger and thumb ends, to carry out day-to-day tasks easily, without having to remove the glove. The long, removable sleeve quickly adapts to many use contexts and changing temperatures during the day. On the side, it features a series of buttons to attach the headgear easily, creating a functional and protective ensemble.
Neapolitan glove-making tradition is characterised by iconic models, such as the Piegolino, and enriched by a wide range of products, such as the drive glove, the perforated glove, the stitched glove, the multicolour glove, etc.
In this context, Glovaclava aims to expand the classic traditional categories and become a new must-have.
An iconic, versatile and practical accessory, present every season and indispensable for new generations, increasingly fascinated by unique products that can interpret their needs, without giving up the outstanding design only Neapolitan tradition can bring along.

SENSITIVE GLOVES
The absence of eyesight, whether temporary or permanent, total or partial, can generate profound discomfort in the visually impaired or blind individuals. This discomfort stems not only from the awareness of being perceived as ‘different’, but also from the fear that this condition may be a hindrance, both to oneself and to those around them.
Tools such as canes for the blind, personal escorts, guide dogs and electronic devices are complementary and often vital solutions to these challenges. However, we need to develop solutions that are not only functional but also meet the criteria of beauty, elegance and simplicity.
Sensitive Gloves fit into this context, as an innovative and versatile product. These gloves, made of perforated leather, are designed to suit all seasons and respond to different needs. Their design features uncovered central fingertips, making it easier to read Braille and improving tactile contact with a person’s surroundings.
Sensitive Gloves are not just a technical support, but rather an everyday ally, capable of improving the quality of life of the visually impaired, combining innovation, design and inclusiveness. This product combines looks and function, and represents a practical and elegant solution to make walking for the visually impaired easier and safer.

LINEAPELLE FASHION STUDIO
Until the beginning of the last century, most master glove-makers purchased alum tanned leathers, which made it relatively easy to recognise their merits and faults and, most importantly, their suitability for making special glove models. Today, however, the introduction of chrome tanning and the improvement of tanning and dyeing systems for glove leathers have led to the centralisation of raw materials into leather and then into gloves in single industrial complexes.
Unlike all other kinds of leather placed on the market already finished – i.e. ready to be transformed into a manufactured product – glove leather must undergo complex preparatory work.
For instance, when producing footwear or other manufactured goods, the most widespread type of leather employed has compact fibres, little elasticity and a smooth surface. The leather is cut in the same way as the fabric to manufacture a suit.
On the other hand, glove leather is more or less soft and elastic, with a natural, unfinished and generally shiny surface. The master glove-maker must take into account different elasticity and thickness characteristics when cutting it, with the latter being somehow mitigated by ‘refining’ or ‘buffing’ the leather being processed.
As part of the Chiroteca Business Network, the Gargiulo leather tannery specialises in the production of glove leathers

CIRCULAR ECONOMY AND SUSTAINABILITY
Research by SSIP focuses on the development of innovative solutions enabling the design of strategies for using waste from the tanning industry, as well as waste from the leather processing chain.
Purpose of the research concerning Circular Economy brought forward by the Italian Leather Research is testing the main strategies for transforming and using waste from the tanning industry scraps, through physical-mechanical, chemical, biotechnological-enzymatic treatments. New applications also include additive manufacturing to reduce the tanning sector’s impact and increase its sustainability, giving new value to waste material.
The main challenges relate to processing approaches for solid tanned waste, which is characterised by significant chemical complexity, compared to waste generated upstream of the tanning stage, from which protein sources for use in fertilisers, biostimulants, and food gelatins can easily be obtained.
Through new approaches to transforming solid tanned waste, processes are currently being tested to obtain circular materials to use first in the tanning process, and then in other sectors of fashion, luxury and design.
Physical/mechanical treatment of solid leather waste;
Additive manufacturing to exploit solid leather waste (including chemical/enzymatic/physical pre-treatment) and development of a new generation of products for the fashion and design industry;
Ball milling treatment for solid leather waste to enhance and develop a new circular finish;
Different types of enabling approaches to exploit solid leather waste for the development of new chemical products and composite/circular materials.

The Italian tanning industry comprises around 1200 companies. Italy produces 130 million square metres of finished leather every year, valued at EUR 5 billion (more than 70% of which is exported).
The tanning industry involves the use of advanced plants for treatment of tanning effluents to produce liquid effluents in accordance with the law. The by-product of these treatments is the tanning sludge, which amounts to approximately 1 tonne per tonne of raw hide to be treated. In a circular economy perspective, exploiting the organic content of tannery sludge to produce energy carriers is a promising strategy to limit its waste, with obvious multiple benefits for the environment.

TEXTILE OVERHAND GLOVE
In the 1950s, Adriano Olivetti opened a factory for state-of-the-art office machines in Pozzuoli, in the heart of southern Italy. The Andreano company was in charge of producing work gloves for the factory workers. Further along, they developed a collection inspired by the work model as a tribute to the excellence and industrial innovation of the time.

MULTICOLOURED GLOVES
The well-designed and stitched glove fourchettes (i.e. strips of material running between the fingers) are a particularly complex element in glove making.
In some models, they are made with a contrasting colour on the palm and back to enhance their silhouette and aesthetics.
By adding coloured strips between the fingers, the glove becomes a classy multicoloured accessory.

PERFORATED GLOVES
Inspired by fabric gloves adorned with lace, the openwork mill was born and has evolved over time thanks to the evolution of digital technologies.
From die-cut to laser cut, perforated gloves models and designs have multiplied exponentially.
From total to partial, from geometric with rhombuses, circles or triangles to floral with soft, sinuous marks.
Particularly suitable in spring and summer, these gloves can be adapted to both classic and sporty looks.

PIEGOLINO
The Piegolino glove is a model characterised by small decorative pleats on the leather, often made on the back or around the wrist. These pleats, obtained by manual pleating techniques, give the glove a unique refinement and timeless elegance.
The Piegolino manufacturing technique symbolizes a high standard of craftsmanship, as it requires great skills and precision to create a harmonious aesthetic effect, without compromising the fit of the glove.
The Piegolino glove dates back to the 19th century, when gloves became an indispensable fashion accessory for upper class men and women. This type of glove was often used for formal events and to complement elegant dresses. The Piegolino technique, developed within the European craft tradition, and in Naples in particular, was conceived to enhance the beauty of the material and add a distinctive touch to leather gloves.
