ALKALI ÖN İŞLEMİN AŞINMA SONRASI LYOCELL DOKUMA KUMAŞ ÖZELLİKLERİNE ETKİSİ

Öz

Bu çalışmada, Lyocell dokuma kumaşlara liflerin fibrilasyon eğilimini azaltmak için çeşitli konsantrasyonlarda alkali ön işlem uygulanmış ve alkali ön işlemin Lyocell kumaşların aşınma sonrası çekme ve yırtılma özelliklerine etkileri incelenmiştir. Alkali ön işlem, Lyocell liflerin fibrilasyonunu azaltmıştır. Bununla birlikte, yanal lif şişmesi nedeniyle artan hacim ve ipliklerin bükümlü yapısının zarar görmesinden dolayı kumaşta çekme meydana gelmiştir. Çözgü/atkı sıklıkları ve krimp oranları, alkali konsantrasyonları arttıkça artmıştır. Alkali ön işlemin neden olduğu dayanım kaybı nedeniyle, işlem görmemiş Lyocell kumaşların kopma ve yırtılma dayanımları, alkali ön işlem görmüş kumaşlara kıyasla daha yüksektir. Aşınma yükü, kumaşlarda lif kırılmalarına ve lif dolaşmalarına neden olmuş ve hem kopma hem de yırtılma dayanımlarını azaltmıştır. Kumaş yüzeyinde uzun atlamalara sahip dokuma türleri, aşınma yüküne maruz kalarak daha fazla hasar görmüş ve bu da daha fazla dayanım kaybı ile sonuçlanmıştır.

INFLUENCES OF ALKALI PRETREATMENT ON LYOCELL WOVEN FABRIC PROPERTIES AFTER ABRASION

Abstract

In this study, alkali pretreatment in various concentrations were applied to Lyocell woven fabrics to decrease the fibrillation tendency of fibers and the influences of alkali pretreatment on tensile and tearing properties of Lyocell fabrics after abrasion were investigated. Alkali pretreatment reduced fibrillation of Lyocell fibers. However, fabric shrinkage occurred because of the increased volume and damaged twisted structure of yarns due to the lateral fiber swelling. The warp/weft densities and crimp ratios increased as the alkali concentrations increased. The breaking and tearing loads of untreated Lyocell fabrics were higher than those of alkali pretreated fabrics since the strength loss caused by alkali pretreatment. The abrasive load caused fiber breakages and fiber entanglements on fabrics and decreased the both breaking and tearing loads. The weave types with long floating interlacements on the fabric surface were more severely damaged by exposing to abrasive load and resulted as higher strength reduction.
