Title:
LIGHT-WEIGHT THERMAL FIBER AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/114281
Kind Code:
A1
Abstract:
Disclosed are a light-weight thermal fiber and a preparation method therefor, wherein a polyester melt is subjected to metering, composite spinneret plate extrusion, cooling, finishing, stretching, thermal-setting and winding to prepare the light-weight thermal fiber; the composite spinneret plate is provided with both hollow spinneret holes and circular spinneret holes; the ratio of the length of the micropores of the hollow spinneret holes to the length of the micropores of the circular spinneret holes is equal to the product of the equivalent diameter ratio of the hollow spinneret holes to the circular spinneret holes and a coefficient K, and the equivalent diameter is the ratio of the cross-sectional area of the spinneret hole to the cross-sectional circumference of the spinneret hole, the range of the value of the coefficient K being 0.97-1.03; a finishing agent used for finishing contains a crown ether, and the content of the crown ether is 67.30 wt% - 85.58 wt%; and a knitting fabric with a gram weight of 100 g/m2 prepared by the obtained light-weight thermal fiber has a heat conductivity coefficient of ≤ 0.150W/m•K. This method is simple and reasonable, and the fiber prepared thereby has both a good light-weight and thermal performance and a good moisture-absorbing and perspiration performance, and has an excellent promotional value.
