Title:
ACRYLONITRILE-BASED FIBER, PILE FABRIC CONTAINING SAID FIBER, AND FIBER PRODUCT CONTAINING SAID FABRIC
Document Type and Number:
WIPO Patent Application WO/2020/045183
Kind Code:
A1
Abstract:
[Problem] Regarding a pile fabric using synthetic fibers, attempts have been made to taper the distal ends of the fibers in order to approach the feel of real fur. However, in the prior art, in addition to a pile processing step, a step and equipment for tapering were also necessary, and sufficient tapering has not been achieved, and thus satisfactory quality has not been obtained. The purpose of the present invention is to provide a tapered fiber which does not require any special steps or equipment, which can be taper processed within the scope of a normal pile processing step, and which can achieve a practically satisfactory, soft feel comparable to real fur. [Solution] An acrylonitrile-based fiber characterized in that the elongation at break point on a load-elongation curve measured in a 150°C atmosphere is 150-900%, the strength at break point is 0.03-0.8 cN/dtex, the flatness is 1.5-10, and the fineness is 1.5-100 dtex.
