Structural design and performance of unidirectional moisture-transfer flat-knitted upper fabric
In order to improve the sweat conductivity of flat-knitted uppers in sports scenes with a lot of sweat on feet,based on the differential capillary effect,9.33 tex/(384 f)DTY was chosen to knit the front of fabric,5.55 tex/(24 f)DTY and 24.44 tex polyester hot melt composite was chosen to knit the back.Five unidirectional moisture-transfer flat-knitted upper fabrics were designed and knitted,and their mechanical properties and thermal-moisture comfortable properties were tested.The results show that the tenacity of the five fabrics was higher than 16 N/mm,the average value of the tear force was higher than 50 N,the appearance rating of the front side of the fabrics on Taber test was higher than or equal to 4 for 2 500 times,and the back side on Martindale test with wool friction fabric was not damaged for 25 000 times,indicating that the mechanical properties of the five fabrics met the relevant national and industry standards for shoe upper.In terms of thermal and humidity comfort,the permeating rate was 150-260 mm/s,the moisture permeability was 3 500-5 000 g/(m2·d),the wicking height was higher than 12 cm,and accumulative one-way transport capacity and overall moisture management capability were rated at 4 or above,indicating that the designed upper fabrics had qualified mechanical properties and good unidirectional moisture-transfer capacity,and provided ideas for the function and structure design of sports shoes for people who are prone to sweating and exercising.
