Description
Technical Field
The invention belongs to the technical field of woven fabrics, and particularly relates to a production process of texture chinlon fabric.
Background
Analyzing the fashion trend of the fabrics in the years, the fabrics can be roughly divided into two categories according to two attitudes of people to urbanization (fast-paced and efficient life style and high-tech life enjoyment), namely boredom and enjoyment: 1) the fabric pursues to return to the original nature, and the original appearance and the texture or the extreme comfortable sensation of the nature are emphasized, so that the fabric gives people a feeling of returning to original; 2) the fabric pursues heavy metal, individuation, taste and the like which young people like. Slowly, garment materials form two styles: low-pitched luxury and fast fashion.
Texture is the texture structure of the surface of an object, i.e. various texture changes of criss-cross, uneven, rough and smooth, and is the expression of human feeling of the physical texture characteristics of a designed object. The texture of the fabric is roughly classified into visual-priority type texture and tactile-priority type texture. The texture in the traditional sense is visual, and the texture means that the surface of the fabric is reconstructed by adopting the traditional processing methods of manual printing, tie-dyeing, wax printing, rubbing, painting, modern computer printing and the like. Only the texture with three-dimensional structure is the comprehensive texture with touch and vision, and the wrinkles have the three-dimensional structure by changing the two-dimensional space on the texture surface of the fabric into a three-dimensional shape, so that the original flat and smooth fabric is converted into a new style with rich layers, changeable unevenness, interesting change and full vitality, and the wrinkles are mainly reflected on the sewing processing of the clothes. For example, the manual texture fabrics such as gambiered silk yarn, which is called 'true silk best quality', have texture with three-dimensional structure, but are manufactured by manual processing, two gambiered silk yarns which are completely identical in a same mode are hardly manufactured, and the fabric needs to be subjected to the processes of 'three-washing, nine-steaming, eighteen-drying', and the like, which are time-consuming and labor-consuming. In addition, the fabrics such as leather, film-sticking embossing and the like and the three-dimensional knitting fabrics with strong concave-convex relief sense also have comprehensive textures of touch sense and vision, but the defects of heavy fabrics or air impermeability and the like are generally existed.
