Abstract

본 발명은 섬유 황단면 형상이 중앙부의 단면부분(1)과 중앙부의 단면부분의 주위에 독립되어 접합된 3~8개의 가지부 단면부분(2)으로 구성되어 있고 중앙부와 가지부 접합부분이 최소폭(W)과 가지부의 단축길이(d₁)의 비(d₁/W)가 2.0~6.0이며 중앙부 최대 내접원의 내경(d₃)과 섬유 황단면의 최소외접원 직경(D)의 비(D/d₃)가 1.8~3.5인 열가소성 탄성체로 된 다엽단면 탄성필라멘트에 있어서 가지부 장축의 길이(d₂)와 단축의 길이(d₁)의 비(d₂/d₁)가 1.2~2.5임을 특징으로 하는 다엽단면 탄성필라멘트에 관한 것으로 자외선과 염소에 의한 강도열화가 개선될 뿐만 아니라 유연한 촉감을 갖는 포면을 얻을 수 있는 효과가 있는 것이다.According to the present invention, the fiber yellow cross-sectional shape is composed of three to eight branch section sections (2) joined independently around the section section (1) of the center section and the section section of the center section, and the center section and the branch section section have a minimum width. The ratio of (W) to the short axis length (d ₁ ) of the branch (d ₁ / W) is 2.0 to 6.0, and the ratio of the inner diameter (d ₃ ) of the largest inscribed circle in the center to the minimum circumscribed diameter (D) of the fiber yellow cross section (D / d ₃ ) is the ratio of the length (d ₂ ) of the major axis of the branch part (d ₂ ) to the length (d ₁ ) of the branch major axis (d ₂ / d ₁ ) of the thermoplastic filament of 1.8 to 3.5 It relates to a multi-leaf cross-section elastic filament to improve the strength deterioration due to ultraviolet rays and chlorine, as well as to obtain a surface having a flexible touch.

The ratio (d ₁ / W) of the short axis length (d ₁ ) of the branch to the branch is 2.0 to 6.0, and the ratio of the inner diameter (d ₃ ) of the largest inscribed circle in the center to the smallest circumscribed diameter (D) of the fiber yellow cross section (D / d ₃ ) Wherein the ratio (d ₂ / d ₁ ) of the length (d ₂ ) of the major axis of the branch to the length (d ₁ ) of the branch major axis is 1.2 to 2.5 in the multileaf cross-section elastic filament made of a thermoplastic elastomer having a diameter of 1.8 to 3.5. Cross section elastic filament.
