Title:
METHOD OF DESIGNING FABRIC HAVING DIFFERENT LIQUID PERMEABILITIES BY CALCULATING FABRIC CAPILLARY LIQUID PERMEABILITY
Document Type and Number:
WIPO Patent Application WO/2020/056949
Kind Code:
A1
Abstract:
The present invention relates to a method for designing and manufacturing a fabric having different moisture absorption and sweat wicking characteristics at a front surface yarn and a back surface yarn of the fabric and for calculating a capillary liquid permeability (LP) per unit area of the fabric. The design method comprises: (1) before structural design of a fabric, measuring and selecting wetting characteristics of front surface yarn and back surface yarn of the fabric, wherein a contact angle of the front surface yarn is less than or equal to a contact angle of the back surface yarn, and the contact angle of the front surface yarn is preferably 10° or more less than that of the back surface yarn; (2) providing a formula for estimating the number of yarn capillaries, using the formula to estimate yarn capillary LP characteristics of the front surface yarn and the back surface yarn, and selecting an appropriate front surface yarn or back surface yarn according to a selection criterion provided by the present invention; (3) estimating capillary LP of a single piece of yarn; and (4) calculating, in conjunction with the structural design of the fabric, coverage areas of the front surface yarn and/or the back surface yarn on a front surface and on a back surface so as to estimate overall capillary LP per unit area of the front surface and the back surface, wherein LPu > LPb, and preferably LPu > 1.3 LPb. The designed and manufactured fabric effectively achieves different LP effects on two sides of the fabric; that is, the liquid content of the front surface of the fabric is higher than that of the back surface of the fabric.
