With improved comfort requirements of clothing, with conduction wet functional fabrics gradually become the focus of the textile industry attention and study. This paper aims to develop a multi-layer knitted fabric with wet permeability function, designed according to the principle of mass transfer in the formation of the cascade guide the experimental program of the wet effect, finishing configuration and materials used are two ways the fabric to achieve a the wet permeability quick-drying effect, and the traditional guide the moist test together with the MMT (liquid water management system), a more comprehensive characterization of the moisture in the fabric of the conduction process, to establish systematic guide wet performance evaluation system. This article by reading a lot of literature, theoretical studies of fabric wet comfort mechanism, summarize and discuss the development rungs guide wet knitted fabrics selected raw materials required, organization and process. Cascade guide wet pathway different experimental part is divided into two blocks, One is formed in layers of wet permeability gradient raw configuration with moisture-wicking ability, choose cotton, fine denier polyester and woven of fine denier polypropylene three materials three lines Tim yarn fabric, to solve the problem of the yarn easily exposed at the end, in the above the basic theory Tim yarn process, with reference to the associated second-tier Tim yarn fabric knitting elements, discussed lapping the configuration of the aspect angle, the yarn tension of the size relationship as well as The yarn properties important factor and orthogonal experiment analysis of the various factors that impact on the Tim Yarn effect, the right weight, the conclusion is the relationship of the three yarn lapping angle β face gt; - β gt; β manner, α surface lt; α of LT; alpha to the yarn tension relationship F to gt; GT in F; F face, veils stiffness is small should be used, the fineness, the friction coefficient of the yarn, the most obvious impact of various factors on the hop yarn lapping angle. Tim yarn to good effect fabric scouring and hydrophilic soft finish, and its moisture-wicking performance evaluation; Second woven with cotton yarn and polyester quilting fabric, using double-sided finishing technology development rungs guide wet knitted. The three knitted inner layer of water repellent outer layer hydrophilic finishing process, including the outer layer of a good additional pressure gradient, so that liquid water directional conduction build on wet quick-drying gradient model. Treatment with a suitable auxiliary tool control two additives in the depth of penetration of the fabric, so that the inside layer 50% of the area by the water-repellent treatment, the untreated region forming the water guiding channel, and uniformly distributed in the inner layer, the appropriate choice of baking temperature and time of the finishing agent solid stable, breathable fabric, quick-drying, liquid water dynamic transfer capability test. The results showed that the three lines add the the quilted fabric yarn fabric and double finishing process given wizard wet clothing thermal-wet comfort is significantly improved. In this paper, the actual production for the newly developed multi-layer conduction wet fabric weaving, finishing the analysis of the process and wet performance evaluation guide, through experimental study to investigate the multi-layer knitted fabric wet a comfortable process theory and technology, establish a comprehensive guide wet performance evaluation system has certain guiding significance for the design of wet permeability function fabrics, characterization wet comfort some reference.
