1. First, check the width and the density of the grey cloth , and test the elastic shrinkage of the grey cloth (take a whole cloth , treat the waste water for 30 minutes, measure the elastic shrinkage after loosening and drying, generally about 30%. The width of fabrics and grey fabrics should be adjusted proportionately according to the size of elastic elongation.The requirements for the warp and weft density should be that the density should be smaller than that of the finished products, and the weft density should be slightly larger than the finished product weft density, so that the fabrics can be processed in wet heat. There is room for contraction during the process to ensure the elastic elongation and feel of the finished product.2
2. When accepting production orders, first of all, it is necessary to clarify the requirements of the customers on quality, especially the requirements on elasticity, shrinkage, width and length. If the billet is processed, it is necessary to know the microstructure of the billet, the sizing slurry, the elastic elongation and shrinkage rate in the warp and weft, and the elasticity of the billet; if the difference between the width of the grey fabric and the finished product is not more than 20%, the grey fabric The elasticity of more than 30%, the finished product of the weft elastic elongation and shrinkage rate is better.
3, due to the different structure of the fabric, and weaving left and right stress is not balanced, and the fabric's edge organization and the main structure is not coordinated. Causes the fabric to be easily curled during the dyeing and finishing process. Therefore, it is required that the twill and satin fabric edges be encrypted, and the longer the floating point, the wider and denser the edge tissue. For example, when weaving latitude fabrics, fabrics with edges up to 2cm wide, the radial density of the fabric edges is 2 to 2.5 times the warp density of the main structure. For this particular fabric, a short process flow is used to control the curling of the fabric. . However, for warp and weft double-elastic fabrics, due to its radial elasticity, the edge structure should be similar to that of the main structure. If the edge tissue is too tight, the shrinkage of the edge structure and the main structure during processing is also inconsistent and can easily cause folds; however, the edge tissue is too loose. , also easy to produce curling.
