Custom Loop Coral Fleece Clothing Fabric

To ensure that wool fabrics are not easy to fade after washing, what color fixing treatment measures have wool fabric manufacturers taken?

When discussing the color fixing treatment measures for wool fabrics that are not easy to fade after washing, our company, as a leader in the field of knitted fabric production, has adopted a series of scientific and efficient color fixing treatment methods with advanced production equipment, professional technical teams and a deep understanding of fabric characteristics. These measures not only improve the color fastness of wool fabrics, but also ensure that the overall quality of the products is in line with international standards, and have won wide praise from domestic and foreign customers.
1. Raw material selection and pretreatment
First of all, at the source of wool fabric production, we select high-quality wool raw materials to ensure that the wool fiber itself has good moisture absorption, breathability and natural elasticity. Before the wool enters the production process, strict pretreatment steps will be carried out, including degreasing and impurity removal, to improve the surface properties of the wool fiber, laying a solid foundation for subsequent dyeing and color fixing treatment. Although this step seems simple, it actually has a vital impact on the subsequent color fixing effect. It is directly related to whether the dye can penetrate evenly and deeply into the wool fiber.
2. Advanced dyeing technology and equipment
Our dyeing plant is equipped with more than 60 advanced low-bath ratio overflow dyeing machines, which can not only significantly reduce water consumption, but also optimize the penetration and bonding process of dyes by precisely controlling dyeing temperature and time. In addition, the introduction of more than 50 Italian finishing dyeing machines has taken the dyeing process to a new level. With their efficient and uniform dyeing performance, they ensure the vividness and consistency of wool fabric colors. In the dyeing process, we use environmentally friendly dyes, which are not only harmless to the human body, but also form strong chemical bonds with wool fibers, thereby improving color stability.
3. Selection and application of color fixers
In order to further improve the color fixation effect of wool fabrics, we use professional color fixers after dyeing. These color fixers can form a thin protective film on the surface of wool fibers, effectively locking the dye molecules and preventing them from falling off during washing. Our carefully selected color fixers not only have excellent color fixation performance, but also maintain the original feel of wool fabrics, avoiding problems such as hardening of the feel or decreased breathability caused by color fixation. Through strict proportioning and process control, we ensure that the fixing agent can be evenly distributed in the wool fiber, so as to achieve the best fixing effect.
4. High temperature setting and post-treatment
After dyeing and fixing, the wool fabric needs to be treated with high temperature setting, which is usually completed on a special setting machine. Through the action of high temperature, the molecular structure of the wool fiber is further stabilized, and the binding force between the dye and the fiber is strengthened, thereby effectively preventing the color change caused by fiber shrinkage or deformation. After setting, we will also soften the wool fabric to restore and enhance its feel, ensuring that the final product is both beautiful and comfortable.
5. Quality inspection and standard compliance
After each process, our company has strict quality inspection links, including color fastness test, abrasion resistance test, shrinkage test, etc., to ensure that each step meets the established quality standards. Especially for the color fixation effect of wool fabrics, we will conduct comprehensive color fastness tests according to customer requirements and international (US) standards, including washing color fastness, rubbing color fastness, sunlight color fastness, etc., to ensure that the product can maintain good color performance under various use environments.
6. Technology R&D and Innovation
As a leading enterprise in the industry, our company has always been committed to technological innovation and R&D. In the field of wool fabric color fixation, we continue to explore new color fixation technologies and materials, such as bio-enzyme pretreatment technology, nano-color fixation technology, etc., in order to further improve the color fixation efficiency and quality while maintaining environmental protection. In addition, we have established cooperative relations with many scientific research institutions at home and abroad to jointly promote the upgrading and development of wool fabric color fixation technology.
7. Special color fixation treatment of fleece fabrics
It is particularly worth mentioning that for the special product of fleece, we have adopted a more sophisticated strategy in color fixation treatment. Because the fleece fabric is reverse-brushed and has rich surface velvet, it is more likely to fall off during washing. Therefore, in the dyeing and color fixation process, we pay special attention to the permeability of the dye and the uniform distribution of the color fixer to ensure that every velvet can be fully protected. At the same time, we have also developed a special post-treatment process based on the characteristics of fleece fabrics to further enhance the durability and stability of its color.
Our company ensures that wool fabrics are not easy to fade after washing through the selection of raw materials, the use of advanced dyeing technology and equipment, the scientific selection of color fixatives, strict quality control, and continuous technological research and development and innovation, providing customers with high-quality, high-value-added knitted fabric products. These measures not only reflect our persistent pursuit of product quality, but also demonstrate our technical strength and innovation capabilities as an industry leader.
