Title:
CROSS-LINKED ACRYLATE FIBER AND FIBER STRUCTURE CONTAINING SAME
Document Type and Number:
WIPO Patent Application WO/2015/041275
Kind Code:
A1
Abstract:
A cross-linked acrylate fiber is known to have high moisture absorption performance, and is used in a clothing field and an industrial material field. However, because the fiber has such properties such that bulk height and shape stability decrease in correspondence with an increase in moisture absorption characteristics, the fiber presents difficulty achieving both high moisture absorption performance and the ease of carding and good bulk height. The purpose of the present invention is to provide: a hygroscopic fiber having both moisture absorption performance for reducing moisture-absorbing exothermic properties and stuffy feeling, and a bulk height for improving heat-retaining properties in a clothing and bedclothes field, which have not been provided by prior art, the hygroscopic fiber being capable of obtaining an excellent web in a carding process; and a fiber structure containing the fiber. The purpose of the present invention is accomplished by a cross-linked acylate fiber characterized in having a cross-linked structure and a 2-10 mmol/g carboxyl group, and having a crimp percentage of 7% or greater.
