What processes are usually carried out in the post-processing stage of rib knit trim fabrics? How to improve the feel and appearance of the fabric through processes such as shrinking and shaping?

Main processes of post-processing of rib knitted trim fabrics
Cleaning and degreasing: The first step of post-processing is usually cleaning, which aims to remove grease, dust and other impurities left in the fabric during the production process. This process is essential for improving the skin-friendliness and breathability of the fabric.
Fleeting treatment: Fleeting is a process that uses physical or chemical methods to make the fibers on the surface of the fabric entangle with each other and become tighter, which can effectively enhance the softness, warmth and elasticity of the fabric. This process greatly improves the comfort and durability of rib knitted trim fabrics.
Setting treatment: Setting is a key step to fix the fabric in a certain shape and size by heating and stretching, which helps to maintain the stability of the fabric and reduce the risk of shrinkage and deformation. Especially for ribbed knitted fabrics, setting treatment can make its stripes more uniform and three-dimensional, improving the overall visual effect.
Softening finishing: In order to further improve the feel of the rib knit trim fabric, Jilida will also carry out a softening finishing process. By using environmentally friendly softeners, after uniform application and drying, the surface fibers of the fabric become smoother and the touch is more delicate and soft. This process not only enhances the wearing comfort of the fabric, but also improves the market competitiveness of the product.
Functional finishing: According to the specific needs of customers, Jilida can also provide functional finishing services such as waterproof, oil-proof, breathable, and antibacterial. These functional finishing agents penetrate into the fabric fibers evenly through special processes, giving the fabric additional protective properties without affecting its original feel and appearance.
How to improve the feel and appearance of fabrics through processes such as shrinking and shaping
Felling process optimization: During the shrinking process, select appropriate shrinking agents and shrinking conditions according to the fabric material (such as cotton, wool, blended, etc.). Wool fabrics use mild bio-enzyme shrinking technology to reduce damage to the fiber and maintain its natural luster and softness; while synthetic fiber fabrics may use mechanical shrinking combined with specific chemical reagents to achieve ideal tightness and elasticity. By precisely controlling the shrinking time and temperature, the feel of ribbed knitted decorative fabrics can be improved while avoiding the negative effects of excessive shrinking.
Shaping process innovation: In the shaping stage, advanced shaping technology and equipment are used to formulate personalized shaping plans based on the characteristics of the fabric. For example, for ribbed knitted fabrics with high elasticity requirements, a low-temperature and long-term shaping strategy is adopted to maintain its good resilience and dimensional stability; for fabrics that need to present specific textures, the three-dimensional sense and visual effect of the fabric are enhanced by adjusting the stretching ratio and direction of the shaping machine. In addition, the company also pays attention to environmental protection and energy saving in the shaping process, and uses technologies such as waste heat recovery to reduce energy consumption.
Comprehensive technology application: In the post-processing process, a complete and efficient post-processing process is formed by integrating multiple processes such as cleaning, shrinking, shaping, softening, and functional finishing. The application of this comprehensive technology not only improves the feel and appearance of the fabric, but also ensures the stability and consistency of product performance, meeting the needs of different fields from fashion apparel to functional sports equipment.

What processes are usually carried out in the post-processing stage of wool knit sweater fabrics? What specific post-processing measures are there for the shrinkage, wrinkle resistance and other properties of the fabric?

1. Main processes in the post-processing stage of wool sweater fabrics
Felling finishing is an important part of the post-processing of wool sweater fabrics. Under hot and humid conditions, the wool fibers are entangled with each other through the continuous action of repeated irregular external forces, which makes the fabric volume smaller, increases the weight per unit area, and forms a layer of short fluff on the surface. This treatment not only improves the appearance of the fabric, but also makes the fabric feel fuller and softer, and enhances warmth retention and elasticity. Jiaxing Zhapu Jilida Garment Accessories Co., Ltd. has advanced shrinking equipment, such as drum washing machines or rotary shrinking machines, which can efficiently and accurately complete the shrinking process. The company's laboratory is equipped with high-precision instruments such as HP value testers to ensure the precise control of pH value during the shrinking process, thereby protecting the wool fibers from damage.
Brightly colored sweaters need to be bleached before dyeing to avoid affecting the color and brightness. Oxidative bleaching combined with reduction and fluorescent whitening processes are used to ensure uniform bleaching and minimize damage to the fabric. The dyeing process uses advanced dyeing equipment and technology to ensure bright and uniform colors, and can reduce various defects such as color flowers and stains on the fabric to improve product quality. The color fastness tester in the company's laboratory can accurately evaluate the color fastness of dyed fabrics to ensure that the products meet international standards.
Finishing is one of the key steps in the post-processing of wool knitted sweater fabrics. Through steaming and shaping, knitted garments have long-lasting and stable specifications and sizes, beautiful appearance, smooth surface, good gloss, full velvet, soft hand feel, elasticity, and a certain degree of fit.
2. Specific post-processing measures for fabric shrinkage, wrinkle resistance and other properties
Wool knitted sweater fabrics have natural shrinkage. In order to improve this property, a series of measures have been taken. On the one hand, during the shrinkage process, by precisely controlling the wet and hot conditions and external forces, the fabric can achieve ideal dimensional stability after shrinkage. On the other hand, the company also uses professional pre-shrinking equipment and technology to pre-shrink the fabric to further reduce the shrinkage rate. In addition, the company's laboratory also provides data support for production by testing the shrinkage rate of fabrics under different conditions to ensure that the shrinkage performance of the product meets customer requirements.
The wrinkle resistance of wool knitted sweater fabrics is one of the important factors affecting its appearance and service life. In order to improve the wrinkle resistance of fabrics, Jiaxing Zhapu Jilida Garment Accessories Co., Ltd. adopts chemical finishing methods. The finishing agent reacts with the groups in the wool fibers to form new chemical bonds, restricting the relative movement between fiber molecules, thereby enhancing the interaction between molecules. This chemical finishing method not only improves the wrinkle resistance of the fabric, but also maintains the softness and feel of the fabric. The company's laboratory also uses an anti-wrinkle performance tester to perform performance tests on the treated fabrics to ensure that the product's anti-wrinkle performance meets international standards.
