SPLITTABLE CONJUGATE FIBER INCLUDING POLYACETAL, AND FIBROUS FORM AND PRODUCT EACH OBTAINED FROM THE SAME

摘要

The invention provides a splittable conjugate fiber excellent in splittability and chemical resistance. The invention also provides a fibrous form and product comprising the fiber with satisfactory productivity. A splittable conjugate fiber comprising a polyacetal and a polyolefin (e.g., polypropylene, polyethylene or the like), wherein the polyacetal satisfies the following numerical expression: Tc′=144° C. [wherein Tc′ represents the crystallization temperature Tc (° C.) when cooling the polyacetal melted at 210° C. at a cooling rate of 10° C./min].
