Title:
THERMALLY ADHESIVE SHEATH-CORE CONJUGATE FIBER AND TRICOT FABRIC
Document Type and Number:
WIPO Patent Application WO/2018/147251
Kind Code:
A1
Abstract:
Provided is a thermally adhesive sheath-core conjugate fiber which has low fuzz generation in a high-order process, exhibits excellent high-order passability even in uses, such as tricot use and the like, requiring a high quality level, enables a woven or knitted fabric having excellent strength, dimensional stability, and durability after thermal adhesion, and has an excellent quality level as a flow path material of a liquid filtration membrane. The thermally adhesive sheath-core conjugate fiber has, as a core part, a polyester having a melting point of at least 250˚C, and has, as a sheath part, a polyester having a melting point which is at least 215˚C and is 20-35˚C lower than the melting point of the polyester constituting the core part. The thermally adhesive sheath-core conjugate fiber is characterized by having a strength of 3.8 cN/dtex or higher and an elongation of 35% or higher.
