Influence of Construction of Textile Material on Performance of Warp Sizing

Abstract

Warp sizing is the precondition of weaving for most textile material. A key fact discussed in this paper is capillary effect, by means of a series of experiments known as observation of suction lift of various types of yarn under non-wetting and wetting condition, a longitudinal and cross section of warp under microscope, tensile breaking strength of sized warp compared between non-wetting sized warp and pre-wetting sized warp, desizing time, etc, it is concluded that the capillary effect is affected by textile material construction such as linear density of warp, spinning process, yarn twist, absorbency .etc, is inherent driving force for size glue penetrating into warp so as to make weaving possible, pre-wetting process will be greatly helpful for penetrating in warp slashing, resulted from capillary effect being enhanced
