Document Type and Number:
Japanese Patent JP7352618
Kind Code:
B2
Abstract:
The present invention relates to a method for designing a functional fabric with differential surface moisture transfer behaviors based on calculation of unit area capillary liquid transportation capacity (LP) at fabric two surfaces respectively. The designed method comprises (1) Identify wettability of the yarn which will be used for fabric out and inner surface individually before fabric structure design; and the contact angle of the yarn which is used for fabric out surface is required to be less than or equal to the one of inner surface yarn. Preferably, the contact angle of the out surface yarn is less than 10° of the one of inner surface yarn; (2) an equation for estimating the total amount of capillaries of a yarn is developed and the liquid transfer behavior of the yarns is calculated accordingly. And the criteria for selecting the out and inner surface yarn is also disclosed in this invention; (3) based on the developed equations, the single yarn's liquid transfer capacity is estimated (4) combined with the structural design of a fabric, the cover ration of top and/or inner surface yarn at fabric two surfaces can be calculated and the result is used to derive the capillary liquid transportation capacity (LP). The invention required that LPu>LPb, preferably LPu>1.3LPb. The designed fabric can achieve an effective differential liquid transportation at fabric two surfaces. The moisture content at the fabric out surface will be higher than it at fabric inner surface.
