INVESTIGATION OF THE EFFECTS OF BLEND RATIO ON PERMEABILITY PROPERTIES OF CASHMERE/COTTON KNITTED FABRICS

Öz

In the context of this study, it is intended to investigate the effects of cashmere/cotton ratio in yarn and fabric density on permeability properties of knitted fabrics. The yarn samples were produced with three different ratios as; 95-5% cotton-cashmere, 90-10% cotton-cashmere and 85-15% cotton-cashmere via vortex spinning system. Then, the yarn samples were knitted with three different loop length values for producing the fabrics as loose, medium and tight structures. In doing so, nine fabric samples were produced. Air permeability and water vapour permeability of these samples were tested as comfort related properties. As a result of the study, it is observed that higher air permeability and lower water vapour permeability values can be obtained by using higher cashmere ratio in yarn structure.

Anahtar Kelimeler

• Cashmere, cotton, air permeability, water vapor permeability, porosity, vortex spinning

KARIŞIM ORANININ KAŞMİR/PAMUK ÖRGÜ KUMAŞLARDA GEÇİRGENLİK ÜZERİNDEKİ ETKİLERİNİN İNCELENMESİ

Öz

Bu çalışma kapsamında, iplikteki kaşmir/pamuk karışım oranının ve kumaş sıklığının örgü kumaşlarda geçirgenlik özelliklerine etkilerinin araştırılması hedeflenmiştir. İplik numuneleri 95-5% pamuk-kaşmir, 90-10% pamuk-kaşmir ve 85- 15% pamuk-kaşmir olmak üzere vortex iplik üretim sisteminde üretilmiştir. Daha sonra iplik numuneleri, gevşek, orta ve sıkı yapıda örgü kumaş üretmek amacıyla üç farklı ilmek uzunluğunda örülmüştür. Böylelikle, dokuz farklı kumaş numunesi elde edilmiştir. Konfor özellikleri olarak hava geçirgenliği ve su buharı geçirgenliği özellikleri test edilmiştir. Çalışma sonucunda, iplikte kaşmir oranının artmasıyla daha yüksek hava geçirgenliği ve daha düşük su buharı geçirgenliği değerlerinin elde edildiği gözlemlenmiştir.

Anahtar Kelimeler

• Kaşmir, pamuk, hava geçirgenliği, su buharı geçirgenliği, gözeneklilik, vortex eğirme.
