DÜZ ÖRME SANDVİÇ KUMAŞLARIN TERMO-FİZYOLOJİK KONFOR VE NEM İLETİM ÖZELLİKLERİNİN ANALİZİ

Bu çalışmada düz örme sandviç kumaşların ısıl konfor ve nem iletim özelliklerine kumaş yüzeyinde kullanılan iplik tipi, monofilament iplik çapı ve monofilament iplik yerleşim açısının etkisi incelenmiştir. Bu amaçla farklı iplik tipleri (multifilament polyester ve Coolmax®) kullanılarak ve monofilament iplik parametreleri (0.28, 0.38 ve 0.48 monofilament iplik çapı ve monofilament iplik yerleşim açısı (askının 3, 5, 7 iğne kaydırılması)) değiştirilerek yedi farklı sandviç kumaş üretilmiştir. Kumaşların hava geçirgenliği, su buharı geçirgenliği ve ısıl direnç gibi termo-fizyolojik özellikleri ile sıvı nem iletim yetenekleri test edilmiş ve istatistiksel olarak değerlendirilmiştir. Çalışmanın sonucunda termo-fizyolojik konfor ve nem iletim özelliklerine etki eden en önemli faktörün yüzeyde kullanılan iplik tipi olduğu tespit edilmiştir. Kanallı yapısı sayesinde Coolmax® içeren kumaşların yüksek hava geçirgenliği, su buharı geçirgenliği indeksi, ısıl direnç ve OMMC değerleri ile daha iyi ısıl konfor ve sıvı nem iletim özelliklerine sahip olduğu belirlenmiştir.

ANALYSIS OF THERMO-PHYSIOLOGICAL COMFORT AND MOISTURE MANAGEMENT PROPERTIES OF FLAT KNITTED SPACER FABRICS

This study aims to investigate the effect of surface material type, monofilament yarn diameter and inclination angle on the thermal comfort and moisture management properties of the flat knitted spacer fabrics. For this purpose, seven different spacer fabrics were knitted by using different type of surface materials (Multifilament polyester and Coolmax®) and by varying the monofilament yarn parameters (yarn diameter of 0.28, 0.38, 0.48 mm and connecting distances of spacer yarns (three, five, seven needles shifting). The thermo-physiological comfort (air permeability, water vapour permeability and thermal resistance) and liquid moisture transport capabilities of these fabrics were tested and evaluated statistically. The results indicated that, the most effective factor on the thermo- physiological comfort and moisture management properties is the raw material. Due to their channelled structure, fabrics containing Coolmax® yarns with higher air permeability, water vapour permeability index, thermal resistance and OMMC values provide better thermo-physiological comfort and liquid moisture transfer properties.
