It is a matter of importance to discuss the elastic behavior of the warp yarn subjected to transverse impact caused by the heald during the weaving.
In the present, a description is given of the equipment built to measure the propagation time of tension in the yarn by the transverse impact loading.
The following results were obtained:
(1) The propagation time of tension ranging approximately from 70 milli-sec/m to 100 milli-sec/m was observed with this experimental apparatus. The propagation velocity of tension was effected by the guide roller R. (See Fig. 1) (It may be substituted by the speed of propagation _??_anging approximately from 10m/s to 14.29 m/s.)
(2) In general, the propagation time of tension in the yarn increases with decreasing Young' modulus of the yarn.
(3) This propagation time of tension in the yarn seemed to be markedly depedent upon the material of fibers in the yarn, and not dependent upon the count of yarn.
