If the content of the yarn on the front surface layer is less than the weight, the touch feeling is poor. If the content of the yarn on the front surface layer exceeds 87% by weight, when the yarn in the middle layer and the yarn in the rear surface layer are relatively reduced, the wrinkle properties and physical properties of the warp knitted fabric are reduced. In other words, the content of the intermediate layer yarn and the rear surface layer yarn is preferably 3 to 20% and 10 to 57% of the total weight of the warp knitted fabric, respectively. If the content of the middle layer yarn and the back surface layer yarn exceeds the above range, the warp knitted fabric has a rough feel; if the content of the middle layer yarn and the back surface layer yarn respectively exceeds the above range and is lower than the above range, the Warp knitted fabrics have degraded shape stability and spinning characteristics. 1 The present invention is characterized in that the untreated warp-knitted fabric is shaved, so that the untreated warp-knitted fabric has a shrinkage of 40% or more before the initial heat treatment.

The elongation recovery I rate j%] [All Appropriate stretch length 10 Knitted fabric Long tension is loose length bell. After a long period of time, the length of the warp is measured according to KSK08 125, but when extended at a constant speed, the long length is output using JISL 1 0 9 6 5. The ends of the warp knitted fabric have a length of 15 cm and a width of 15 cm. It was fixed to Instron, and the warp was fixedly stretched at an extension speed of 100 mm / min until the constant speed extension reached 750 g. When the fixed-speed elongation pull is removed, the warp is opened. Then, the warp knitted fabric was stretched to the original speed at a fixed speed. Then, when the tensile load of the warp knitted fabric was removed, it was loosened for three minutes and the above test was repeated five times. Finally, measure the stretch L and the loosening length L1 of the warp knitted fabric. Subtract the stretched knitted fabric recovery length from the stretched length l to obtain the warp knitted fabric's loosening length L1 (see section 由), which is substituted by Yan Hai, warp knitted fabric's stretched length L and loosened length L1.
