    CHITOSAN ADDED COMPOSITE VISCOSE YARN AND ITS POTENTIAL APPLICATION FOR DENIM FABRIC DEVELOPMENT
    (Technical University of Liberec, ) KORKMAZ, AHMET; BABAARSLAN, OSMAN; Technická univerzita v Liberci
    The rapid increase in consumption has led to the decrease and even extinction of natural resources on earth. The textile industry also has an important place in terms of consumption. The transition to more sustainable biodegradable products instead of established fossil-based materials has increased rapidly due to textile manufacturers and related industries, legal regulations, social responsibility commitments and increasing ecological awareness of customers. Developing new environmentally friendly, biodegradable material groups with new technologies or by modifying existing technologies has been the main goal of many researchers. In this context, we aimed to develop denim fabric that is effective against strong hospital bacteria by using the yarn containing biopolymer chitosan as a weft in denim production. Chitosan finds wide application in the textile industry due to its biodegradability, antibacterial activity and many more functionalities. Chitosan is used in biomedical textile applications in the textile industry, either as a wound healing, hemostatic (blood stopper), antibacterial, antifungal, either alone or modified to various derivatives or combined with other materials. In this context, instead of using chitosan as a coating material in our studies, chitosan-containing yarn was used in the production of denim fabric in order to distribute the chitosan more homogeneously and to increase the washing resistance. As a result, it was determined that the denim fabric developed by using chitosan-based yarn in weft in denim production reduces hospital bacteria (MRSA-Methicillin resistant staphylococcus aureus) by > 99%.

    INVESTIGATION OF THE USAGE OF ALTERNATIVE NEW GENERATION ECO-FRIENDLY FIBER BLENDS IN SYNTHETIC BASED DENIM FABRICS
    (Technical University of Liberec, ) ŞARAPNAL, DILEK; BABAARSLAN, OSMAN; Technická univerzita v Liberci
    Polyester yarn is made from post-consumer waste such as bottles, fabrics, etc., in the composition of polyester ethylene terephthalate (PET). Polyester (mainly polyethylene terephthalate, PET) is the most commonly employed textile fibre with over 50% share in total production of textile fibres. Pla is a biobased and biodegradable polymer produced from renewable resources. PLA is also a thermoplastic aliphatic compostable polyester. In this study, 75% Cotton - 25% PLA, 75% Lyocell - 25% PLA and 75% Cotton - 25% PET blended yarns were produced as rigid, corespun and dualcore in the ring spinning system .The fabrics were weaved with produced yarn. In the finishing processes, some of the fabrics were treated with caustic and some of the fabrics were only washed. Fabrics containing PLA and PET were compared with each other. Fabrics containing PLA and PET fiber were evaluated in terms of strength, elasticity, abrasion and pilling performances. Although the weft tensile and tear properties of Cotton-PLA blended fabrics are lower than Lyocell-PLA and Cotton-PET blends, it has been indicated that PLA blended yarns can be used as an alternative to PET based yarns and fabrics.
