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.
