Giysilerin terleme ile sonuçlanan herhangi bir aktivite sonrasındaki kuruma davranışları giysi konforu açısından büyük önem

taşımaktadır. Bu çalışmanın amacı, günlük ve spor giysilerde giderek artan kullanıma sahip rejenere selüloz liflerinden elde edilen

kumaşların kuruma kinetiklerinin analizi ve modellenmesidir. Kurutma denemeleri, modal ve liyosel kumaşların kuruma davranışlarının

benzer ve kuruma hızlarının viskon kumaşlara göre daha yüksek olduğunu göstermiştir. Nem yönetim testleri, rejenere selüloz

kumaşların kuruma davranışlarının direkt olarak sıvı nem yayma kapasitesiyle ilişkili olduğunu doğrulamıştır. Kuruma davranışının

modellenmesi için doğrusal regresyon ve ince-tabaka kurutma eşitliklerinin kombinasyonu olan iki aşamalı bir model yaklaşımı

kullanılmıştır. Logaritmik model, rejenere selüloz kumaşların azalan hızda kuruma periyodunu en uygun açıklayan eşitlik olarak

bulunmuştur. Ayrıca, önerilen modelin kuruma hızlarının hesaplanması için yeterliliği de kanıtlanmıştır.

Anahtar Kelimeler

Rejenere selüloz, giysi konforu, kurutma eğrisi, ince tabaka kurutma modelleri, nem iletimi

MODELLING OF THE DRYING BEHAVIOUR OF REGENERATED CELLULOSIC FABRICS

Öz

Drying behaviour of garments during wear after any activity resulted in sweating is of great importance in terms of clothing

comfort as well as heat and water vapour permeability for functional clothing design. The aim of this study is to analyze and model the

drying kinetics of regenerated cellulosic fabrics which have increasingly use in casual clothing and sportswear. Simulated drying

experiments showed that modal and lyocell fabrics have similar drying behaviour although their supramolecular arrangement is quite

different and drying rate is higher than viscose fabrics. Moisture management tests proved that the drying behaviour is directly

connected to the liquid moisture spreading capability of regenerated cellulosic fabrics. A two-stage modelling approach which is a

combination of linear fit and thin-layer drying equations was tested for modelling of drying behaviour. Logarithmic model was found to

be the best fitted equation to represent the falling-rate drying period of regenerated cellulosic fabrics. Moreover the sufficiency of the

proposed model for the computation of drying rate was also proved.
