In the process of jet dyeing, chenille yarn can be freely suspended, allowing the velvet yarn to stand up and heat treated, and then the round yarn result will occur. Because of abundant contact, the handle of Chenille yarn is better, which is more successful than dyeing in vertical vat.
In vertical vat dyeing, the yarn is fixed and the dye cycles in the vat. The dyed yarn is a flat chenille yarn. And the quality is not very ambitious, because the yarn hanging between the two is easily printed.
The shrinkage degree of yarn in the dyeing process will affect the final yarn width. For example, the shrinkage degree of acrylic chenille yarn in dyeing is within 3-5%. If the shrinkage degree of yarn can be considered in the process of manufacturing chenille yarn, the impact of shrinkage will be avoided. Because the fabric is woven by chenille yarn, the result of heat treatment in the dyeing process will affect the result of finished product.
Chenille yarns with different shapes and various types can create rich visual benefits and adapt to various planning requirements, especially in the field of decorative fabrics, which has been popular in recent years. The Chenille yarn with the outer linear structure, with proper pictures and texture planning, can give people a sense of harmony and elegant temperament. In this paper, high shrinkage materials are used to develop and produce concave after reasonable placement, collocation and post-rectification.
High shrinkage polyester is used to develop new chenille yarn fabric. This paper mainly expounds the formation of the concave-convex benefits of fabrics from the application of materials and the collocation of placement, further reflecting the plump characteristics of Chenille yarn in fabrics.
The surface method of chenille yarn density control, and after selecting four kinds of chenille yarn for practical verification, the results show that the error between the linear density of chenille yarn calculated by the surface method and the actual measured linear density is below+7.5%, and the fineness and number of core yarn, the fineness and number of cashmere yarn and the width of cashmere yarn have a strong impact on the linear density of chenille yarn.
Chenille yarn is also called corduroy or plush yarn. As a kind of fancy yarn, it has the characteristics of plump, loose, soft feel and bright color. The fabric woven with it is strong and light. These characteristics are widely used in many fields such as home textile decoration fabrics, woven knitted clothing, automobile decoration articles and antique fabrics, and are deeply loved by people. The planning change of Chenille yarn density is limited.
