KİTOSANIN TEKSTİL SANAYİİNDE ANTİMİKROBİYAL MADDE OLARAK KULLANIMININ ARAŞTIRILMASI

Dünyada çapında, büyük miktarda yengeç ve karides gibi, su ürünlerinin kabukları değerlendirilmeden çevreye atılmaktadır. Günümüz artan çevre yasaları ve atıkların yeniden değerlendirilmelerinin gündeme gelmesiyle birlikte, bu kabuklardan yeni ürünler elde edilmeye başlanmıştır. Bu ürünlerin başında kitin gelmektedir. Kitin, dünyada selülozdan sonra ikinci en yaygın biyopolimerdir. Kitinin deasetilasyonu sonucunda başlıca türevi olan kitosan elde edilmektedir. Kitin ve kitosan kimyası üzerine yapılan araştırmalarla birlikte uygulama alanları da paralel olarak artış göstermektedir. Kitosan, birçok sektör gibi tekstil sanayinde de antimikrobiyal madde, lif eldesi, pamuk boyama, yün boyama ve keçeleşmezlik kazandırma gibi birçok alanda geniş kullanım alanı bulmuştur. Bu çalışmada, kitosanın tek başına ve farklı konsantrasyonlarda çapraz bağlayıcı ile çeşitli fiksaj koşullarında antimikrobiyal etkinliği ve yıkama dayanımları incelenmiştir. Deneme sonuçlarından, DMDHEU ve kitosan kombinasyonunun çoklu yıkamalara karşı, tek başına kitosan kullanımına kıyasla çok daha iyi sonuçlar verdiği görülmüştür

INVESTIGATION OF THE USAGE OF CHITOSAN AS AN ANTIMICROBIAL AGENT IN TEXTILE INDUSTRY

Huge amount of crab and shrimp shells have been abandoned as wastes worldwide. These wastes are reprocessed as a result of increased environmental laws and new products have been produced from these shells. Chitin has become the most preferred form of them and it is also the most abundant biopolymer after cellulose in nature. Chitosan, the main derivative of chitin, is obtained by deacetylation of chitin. Application areas of chitin and chitosan have been increasing together with the researches made on them. Like most of other industries, Chitosan has the most common application possibilities in textile industry such as antimicrobial agent, spinning, cotton, wool dyeing and shrink proofing of wool fibers. In present study, the effect of chitosan and crosslinking agent at different concentrations on antibacterial efficiency and washing durability were investigated. The combination of DMDHEU and chitosan was found to give better results against multiple washings than that of chitosan alone
