modified cotton and cotton, where is the different
1. Mimic cotton fiber properties
❖ imitation wool sense and bulk: polyester filament cluster sex is higher, the surface is smooth, to make its surface type cotton wool feeling, need to change the fiber structure. At present, there are two ways to improve the wool feeling and swelling property of polyester, one is to use air to blow away the filament so that it forms irregular structure, the other is to use different materials combination to form three-dimensional curly swelling form.
❖ imitation of cotton fiber moisture absorption: the way to improve polyester hygroscopicity mainly includes: the use of fine denier or specific surface area of the wire increases superfine fiber, improve the capillary core absorption speed; The fiber section is modified to increase the hygroscopic channel and accelerate the hygroscopic speed. The hydrophilic group is added to the fiber to enhance the hygroscopicity of the fiber.
❖ to imitate the luster of cotton fibers: to improve gloss and achieve the result of imitation cotton polyester, to let the fiber surface diffuse, weakening its light reflection ability. The surface of the fibers can be modified or fine denier/superfine denier fibers can be used to improve their diffuse reflectivity.
2. Make up for defects in cotton fiber
The characteristics of polyester can be used to make up for the shortage of cotton fiber. Such as polyester light resistance, heat resistance, mildew resistance and other good performance, can make up for the fiber fabric durability; Polyester initial modulus is large, stiff, not easy to deformation, can make up for cotton fabric easy to wrinkle, easy to deformation, not wear-resistant and other deficiencies.
1. Organizational structure
The cotton shape effect of super imitation cotton depends on the fabric structure first. In order to strengthen the hygroscopicity of the super-imitation cotton fabric, the fabric structure is designed according to different application fields of the fabric, sometimes plain weave, sometimes twill weave.
2. Set the warp and weft density
Due to the special properties of super imitation cotton fiber, considering the shrinkage characteristics of the fiber in the post-finishing process, the warp and weft density should be designed properly, so that the fiber can fully reflect the thick and fluffy feeling of the fabric after thermal shrinkage.
3. Dyeing and finishing process
To a large extent, the imitation effect of super - imitation cotton fiber is reflected by post-finishing. Two of the more typical is the soft pull set finish and blanket finish. Because polyester modulus is larger, the fabric performance is more crisp, wearing will be uncomfortable. To make the fabric with a moderately soft feel, the fabric needs to be soft finishing, and in the process of fabric shrinkage, stretch shape, in order to strengthen the cotton fabric. Cloth blanket finishing will make the fabric more plump, soft, further improve its fidelity and wearability.
The application of super imitation cotton products
Superimitated cotton is not only close to cotton fabric in fiber surface shape and fabric style, but more importantly, its fabric is imitated cotton and superimitated cotton in performance and function, and has excellent dynamic thermal and humid comfort performance. Therefore, super imitation cotton fiber can be widely used in sportswear, casual wear, shirts, underwear, outerwear, home textile and other products.
