MANAGEMENT OF PROCESSING AND RECOVERY OF LEATHER WASTE

The leather and leather goods industry development is conditioned by the development of the supply of raw materials - animal husbandry and chemical industries, sectors that tend to develop intensive on vertical - which causes a shortage of raw materials in relation with the market demand for quality products. The leather is the basic raw material of the leather and leather goods industry, this raw material is the most substantial contribution to downstream sectors, giving them a competitive advantage and it is known that the leather has the greatest potential to add value to the products in which it is incorporated. The advantages of using leather are many, the most important qualities are its hygienic properties, flexibility and adaptability to a wide variety of applications. Leather is manufactured on demand for each type of application, such as shoes, clothes, gloves, handbags, furniture upholstery or car interiors, yachts and planes. It requires better use of raw materials by using new technologies and manufacturing processes based on non-invasive methods on the environment leading to increase the product life cycle. The leather and leather goods industry is a supplier of large amounts of waste from the production cycle, waste that has the same properties and qualities as raw material used in the base product. Leather waste represents a loss for the companies, an additional cost related to storage and environmental protection

Heritage ethnographic objects - antimicrobial effects of chitosan treatment

[EN] Chitosan is a natural polymer, which presents, according to studies made up to present, low toxicity and good biocompatibility. Recent studies are focused not only on its antimicrobial effects on textiles, because this polysaccharide leads to improvements such as: shrink resistance, dye uptake etc. Two Romanian traditional shirts were non-invasively tested by applying Chitosan and by investigating the SEM images, before and after applying the chitosan. The paper underlines the surface modifications of tested textiles using chitosan. The odd agents on the fibres surfaces were removed and the limitation of the number of microorganisms was observed[Otros] Chitosanul este un polimer natural care, conform studiilor realizate pân¿ în prezent, prezint¿ o toxicitate sc¿zut¿ ¿i o bun¿ biocompatibilitate. Studii recente, care se concentreaz¿ nu doar pe efectele sale antimicrobiene asupra materialelor textile, au eviden¿iat c¿ aceast¿ polizaharid¿ conduce la îmbun¿t¿¿iri din punctul de vedere al rezisten¿ei la contrac¿ie, precum rezisten¿a la contrac¿ie, absorb¿ia coloran¿ilor etc. Dou¿ c¿m¿¿i tradi¿ionale române¿ti (ii) au fost testate neinvaziv prin aplicarea chitosanului ¿i prin investigarea imaginilor SEM, înainte ¿i dup¿ tratamentul cu chitosan. Lucrarea eviden¿iaz¿ modific¿rile de pe suprafa¿a ¿es¿turilor testate folosind chitosan. Dup¿ îndep¿rtarea agen¿ilor de pe suprafa¿a fibrelor, s-a remarcat reducerea num¿rului de microorganismeThe research was possible by equal scientific involvement of all authors and acknowledges the support of the Grant PN-III-P1-1.2-PCCDI-2017-0686Indrie, L.; Bonet-Aracil, M.; Ilies, DC.; Albu, AV.; Ilies, G.; Herman, GV.; Baias, S....
