Definitions
- FIG. 1 graphically shows the intensity curve of X-ray diffraction pattern of a-type crystalline structure
- a process for producing low crimp PEOB yarns having silk-like properties which is characterized in that a PEOB multifilament drawn yarn having a B-value of from 20 to 80 and a shrinkage value in boiling water of from 20 to 35 percent is heat-treated under substantially no tension so as to give a decrease of more than l in B-value.
- An object of the present invention is accordingly to provide a process for producing PEOB drawn yarns having low crimps in a simple manner.
- shrinkage in boiling water in this specification denotes (A B/A) X l wherein A: length of a sample loaded with a weight of 1/30 g/total denier prior to treatment in boiling water,
- Example 1 1 A drawn PEOB yarn (50 deniers/24'filaments) which was Sample No. 7 of Examples 1-5 (B-value: 33.2;
- ammonium carbonate (foaming agent) 1.0%
