YUMUŞATICI UYGULANMASININ FARKLI İPLİK YAPILARININDAN ÜRETİLMİŞ PAMUKLU ÖRME KUMAŞLARIN HAVA VE SU BUHARI GEÇİRGENLİKLERİNE ETKİSİ

Yumuşatıcılar, giysilerin üretimi ve bakımında sağladıkları his ve koku özellikleri nedeniyle sıklıkla uygulanırlar. İnsan vücudunun termal dengesini sağlamak için, kumaşların hava ve su buharı geçirgenlikleri önem taşımaktadır. Bu noktadan yola çıkarak, uygulanan yumuşatıcıların hava ve su buharı geçirgenliklerine olan etkileri çalışmada ayrıntılı olarak irdelenmiştir. Çalışma esnasında ayrıca boyamanın bu özelliklere olan etkisini de incelemek adına, ağartılmış ve ağarttma sonrasında boyanmış kumaşlara ayrı ayrı yumuşatıcı uygulanmıştır. Yumuşatıcı tipinin etkisini de araştırmak için katyonik, non-iyonik ve silikon yumuşatıcı çeşitleri ve bu yumuşatıcıların üç farklı konsantrasyonu open-end ve ring ipliklerden üretilmiş % 100 pamuk ipliğinden üretilmiş süprem kumaşlara uygulanmıştır. Elde edilen değerler ANOVA ve t-testi ile istatistiksel olarak değerlendirilmiştir. Elde edilen sonuçlara göre; open-end ipliğinden yapılan kumaşların hem hava hem de su buharı özellikleri daha iyidir ve boyama işlemi kumaşların bu özelliklerini önemli bir şekilde etkilemektedir. Yumuşatıcı ile mamul edilen kumaşların geçirgenlik özellikleri düşerken, non-iyonik yumuşatıcıya tabi olmuş kumaşlar daha iyi performans göstermiştir.

EFFECTS OF SOFTENER APPLICATIONS ON AIR AND WATER VAPOR PERMEABILITY OF COTTON KNITTED FABRICS PRODUCED WITH DIFFERENT YARNS

Softeners are commonly applied during manufacture and care of garments, mostly for improved feel and odor they offer. However, they alter some of the properties of the textile materials on which they are applied. To achieve the thermal regulation of the human body, air and water vapor permeability properties of the fabrics are very important parameters. From point of this view, it was the aim of the study to investigate the effects of softener on air and water vapor permeabilities of the fabrics. For a deeply investigation; cationic, non- ionic and silicone were selected as softener types, and they were applied at various concentration levels (0, 1, 2, 3 %) on bleached or bleached&dyed fabrics which were knitted by using ring or open-end yarns. To evaluate the results ANOVA and t-test analyzes were used. According to the results, fabrics made from open-end yarn showed better air and water vapor permeability. In addition to that, additional wet process was shown to change the permeability properties of knitted fabrics. Also, treatment with softener affected permeability properties negatively, but the effects of concentrations of the softeners studied were more significant on air permeability than those on water vapor permeability. Furthermore, among the softeners studied, non-ionic softener performed superior to cationic and silicone softeners in terms of air and water vapor permeability.
