Humans have found a lot of inspiration from the development and evolution of natural organisms, and developed many ultra-fine synthetic fibers, which are soft to the touch, excellent in drapability, and comfortable to wear. They are currently the focus of research and development of ultra-fine fibers in various countries around the world. All major varieties of synthetic fibers in the industry, such as polyester, polyamide, polyacrylonitrile, polypropylene, etc., can be obtained through certain technical means to obtain superfine fiber varieties. At present, the industrialization of superfine polyester is more mature than other fibers, and it occupies a dominant position in textile fibers.
The most remarkable feature of microfiber is that its monofilament linear density is much lower than that of conventional ordinary fibers, the thinnest of which can reach 0.0001 dtex. Due to this remarkable feature of ultrafine fibers, it has many properties different from ordinary fibers.
For example: soft and delicate feel and good flexibility
The monofilament cross-sectional diameter and monofilament fineness of superfine fiber are smaller than natural fibers, so its crimp modulus is lower, so the fabric has better softness; its monofilament has low bending stiffness, so its fabric has Good draping performance; Compared with ordinary fibers, the crystallinity and orientation of ultrafine fibers are higher, which improves the relative strength of the fibers, so the bending strength and repeated bending strength of the fibers are improved, making them more flexible and smooth. And feel soft. However, these properties are also related to its fabric structure, blended fiber components, blended fiber ratio, etc. At the same time, for textured yarns, the decrease in monofilament fineness will lead to poor bulkiness
