초록
PET 중공필라멘트 복합 DTY(Draw Textured Yarns)와 ATY(Air-jet Textured Yarns)는 경량의 스포츠 의류를 포함한 고감성 의류용으로 많이 사용되고 있다. 본 연구는 중공섬유 복합 DTY와 ATY 복합사 직물의 수분 및 열이동에 관계되는 쾌적특성에 중공 복합사 및 직물의 구조 특성이 어떠한 영향을 미치는 가에 대한 분석이다. 기공의 크기가 큰 중공 복합 직물의 흡수성이 우수하였고 커버팩터는 영향을 미치지 않았다. 또한 ATY사 직물이DTY사 직물에 비해 흡수성이 우수하였다. 반면, 건조특성은 기공 사이즈가 미세한 직물이 기공사이즈가 큰 직물보다 건조시간이 짧았으며 낮은 커버팩터와 기공 사이즈가 작은 하이멀티사 직물이 중공 복합직물에 비해 건조특성이 우수하였다. 직물의 기공 사이즈는 공기투과도와 열전도도 특성에 가장 중요한 인자였다. 직물의 큰 기공도는 중공 복합 직물의 기공도와 열전도도에 비선형적인 반비례 상관관계를 나타냈다.
Abstract
Composite draw textured yarns(DTY) and air jet textured yarns(ATY) with hollow PET filament have been usedfor making high emotional fabrics including light weight sports wear garments. This study investigated effect ofhollow composite yarns and fabric structural parameters to the comfort properties related to the moisture andthermal transport phenomena for the composite fabrics made of DTY and ATY with hollow PET filament. Wickingproperty of hollow composite fabric was superior at the high pore size fabric and was not influenced by fabriccover factor. Wicking property of the fabric with ATY was better than that of the fabric with DTY. On the otherhand, drying rate of fine pore sized fabric was shorter than that of large pore sized fabric and drying rate of highmulti yarn fabric with low cover factor and small pore size was superior than that of hollow composite fabric. Thepore size of the fabric was dominant factor in the air permeability and thermal conductivity of hollow compositefabric. High pore sized fabric showed high air permeability and thermal conductivity of hollow composite fabricwas nonlinearly inversely proportional to pore size of the fabric.
