ENDÜSTRİYEL VE TÜKETİCİ SONRASI ATIKLAR İLE TİCARİLEŞEBİLİR DENİM KUMAŞ ÜRETİMİ

Bu çalışmanın amacı, sıfır atık konseptine uygun olarak kaliteden ödün vermeden %100 geri dönüşüm denim üretimidir. Öncelikli olarak denim kumaş üretim sürecinde hammaddeden mamule atık noktaların tespiti yapılmıştır. Sonraki süreçte endüstriyel atıklar (denim sektöründe geri kazanılan pamuk lifleri) ve tüketici sonrası atıklardan (PET şişe atıklarından geri kazanılan lifler) denim kumaşlar üretilmiştir. Bahsedilen liflere ek olarak olumsuz yönleri elimine edebilmek için klasik pamuk lifleri ve rejenere selülozik Tencel® lifleri de taşıyıcı lifler olarak çalışmada kullanılmıştır. Yapılan tasarıma ve konstrüksiyona bağlı olarak, lif tiplerinin iplik veya kumaş karakteristikleri üzerine etkisi araştırılmıştır. Ayrıca, lifler ve iplik/kumaş sonuçları arasındaki ilişki korelasyon analizi ile istatistiksel olarak değerlendirilmiştir. Araştırmanın sonuçları lif miktarının iplik düzgünsüzlüğü, kalın yer, neps, tüylülük, kumaş hava geçirgenliği ve aşınma direnci üzerinde önemli etkiye sahip olduğunu göstermektedir

COMMERCIALIZED DENIM FABRIC PRODUCTION WITH POST-INDUSTRIAL AND POST-CONSUMER WASTES

The purpose of this study was to produce 100% recycled denim without a tradeoff in quality according to zero waste concepts. Initially, the waste points from raw materials to final product in denim fabric production process were determined. Then, denim fabrics were produced from post-industrial (recycled cotton fibers obtained from denim wastes) and post-consumer wastes (produced from recycled PET bottles). Classic cotton fibers and alternative regenerated cellulose fibers (Tencel®) were used as carrier fiber in addition to mentioned fibers for eliminating recycled fibers disadvantages. The effect of fiber types on yarn or fabric characteristics were investigated in accordance with planning design and construction. Furthermore, the relationships between fibers and yarns/fabric results were statistically evaluated using correlation analysis. The results of this investigation show that the amount of fibers have a significant effect on yarn unevenness, thick places, neps, hairiness, air permeability and abrasion resistance of the samples
