Title:
THERMAL SPLITTING TYPE CONJUGATE FIBER AND NONWOVEN FABRIC THEREOF
Document Type and Number:
Japanese Patent JPH02169720
Kind Code:
A
Abstract:

PURPOSE: To obtain the subject conjugate fiber capable of splitting a high- melting component by heat treatment and providing nonwoven fabrics having soft hand by arranging a polyolefin component and incompatible fiber-forming polymer component in a specific state.

CONSTITUTION: A thermal splitting type conjugate fiber, obtained by regulating the melting point difference between a polyolefin component (A) and a fiber- forming polymer component (B) (polyester, nylon, etc.) incompatible with the component (A) to ≥20°C and arranging both components in a state of both components partially exposed to the fiber surface and the high-melting component in a state of split into plural parts and capable of splitting the high-melting component. The fiber is formed into an ultrafine shape by dividing and splitting the high-melting component. If the fiber is used in nonwoven fabrics, the polyolefin component is uniformly bonded between interstices of the ultrafine fibers in the form of dots.
