Title:
YARN MIXTURE, MOLDED ARTICLE OF YARN AND PRODUCTION OF MOLDED ARTICLE OF YARN
Document Type and Number:
Japanese Patent JP3185575
Kind Code:
B2
Abstract:

PURPOSE: To obtain a molded article of yarn hardly being heated due to high air permeability and water vapor permeability, having excellent water vapor absorption, showing a stable shape because of low compression residual strain, hardly yielding despite of lightness and softness and having a refreshing feeling in use.
CONSTITUTION: In a yarn mixture comprising 40-80wt.% of conjugated yarn obtained by combining a polyether ester amide R1 as a core part with a polyester R2 as a sheath part and 20-60wt.% of conjugated yarn prepared by combining a polyester R3 as a core part with a polyester R4 as a sheath part, the characteristic of this yarn mixture is that the melting point of the polyester R4 is lower than the lower melting point of the polyester R2 or the polyester R3 and the weight ratio of the polyester R3/R4 is in a range of 40/60-80/20. Since the yarn mixture has excellent multi-directional cutting properties and is readily molded depending upon the use purpose, the molded article of yarn has improved workability in production and has advantage of exerting no adverse effect on environment because no chlorinated fluorocarbon gas is used.
