How to optimize abrasion resistance, comfort and color fastness during the production of Polyester-Cotton Piece-Dyed Corduroy Fabric?

When producing Polyester-Cotton Piece-Dyed Corduroy Fabric, to improve its wear resistance, comfort and color fastness, it is necessary to comprehensively consider the selection of fabric materials, optimization of process flow and post-processing.

By adjusting the ratio of polyester to cotton, the comfort and durability of the fabric can be balanced. Generally speaking, polyester can increase the wear resistance of the fabric, while cotton helps to improve comfort. The appropriate polyester content (such as 30-40%) can enhance wear resistance while retaining the softness of cotton fibers. Selecting wear-resistant long-staple polyester and high-count cotton yarn can improve the strength and feel of the fabric while reducing pilling.

By increasing the fabric density of corduroy (tighter yarn arrangement), wear resistance can be improved, the shedding of fluff can be reduced, and the overall strength can be enhanced. A stronger connection method is used between the velvet surface and the base fabric of the corduroy to prevent the fluff from being worn. Increasing the distance between the cords can reduce friction and make it more wear-resistant. Through pre-shrinking and shaping processes, the subsequent deformation of the fabric is reduced, and its durability and dimensional stability are enhanced.

Polyester-cotton dyed corduroy generally uses a combination of disperse dyes and reactive dyes. Choosing dyes with high color fastness, such as disperse dyes for polyester parts and reactive dyes for cotton fibers, can ensure that the color is full and not easy to fade. Improve the control of the dyeing process to ensure that the dyes are evenly penetrated into the polyester and cotton fibers, making the dyeing more stable and avoiding fading caused by light or washing. Using digital inkjet printing or cold transfer printing technology can reduce the damage to the fiber caused by traditional dyeing, enhance color fastness, and meet environmental protection standards.

Anti-pilling treatment (such as enzyme treatment, anti-pilling coating, etc.) can be used to enhance wear resistance and reduce pilling caused by friction. Adding wear-resistant finishing agents can form a protective layer on the surface of the fabric and reduce friction loss. Softener treatment and silicone oil treatment can increase the softness and smoothness of the fabric, improve comfort, and make the corduroy feel smoother. Especially when containing polyester components, antistatic finishing can reduce the adsorption of dust by the fabric and keep the fabric clean and beautiful.

Add wear resistance tests (such as Martindale wear test) during the production process to ensure that the wear resistance standards of the fabrics meet the standards, thereby improving the quality control of the products. Strict color fastness tests such as light fastness, washing fastness, and friction resistance are carried out on dyed fabrics to ensure that the finished products have excellent color fastness and avoid fading caused by wear and washing during use. Add fabric tensile, tear strength and pilling tests to comprehensively evaluate the actual performance of the fabrics and make corresponding process improvements.

Some environmentally friendly nano-coating technologies can not only enhance the stain resistance and wear resistance of fabrics, but also prevent fading caused by washing or light, thereby extending the service life of fabrics. The application of modern digital dyeing technology (such as ultrasonic dyeing or plasma treatment) can make the dye penetrate into the fabric more evenly, reduce resource consumption in the dyeing process, and conform to the trend of sustainable development.

Add waterproof and oil-proof treatments to polyester-cotton corduroy to increase its application scenarios. For example, through hydrophobic and oleophobic finishing technology, corduroy fabrics will be easier to clean and have longer durability. To increase comfort, a small amount of elastic fiber (such as spandex) can be added to the fabric to improve its stretchability and fit, making the fabric softer and suitable for underwear.

Through the above-mentioned multi-faceted process improvements, polyester-cotton dyed corduroy can improve its softness, color fastness and service life while maintaining wear resistance, meeting the needs of various complex environments and improving the user's wearing experience.
