What is imitation cotton lint? What kind of fabric is imitation cotton velvet? Imitation cotton lint is polyester superfine fiber. Polyester superfine fiber is a new product with high quality, high performance, high technology content and high added value. Its monofilament thread density is much lower than that of conventional polyester fiber, which gives it excellent wearing properties that are different from conventional polyester fiber, such as moisture absorption, breathability, soft hand feeling, fullness, elasticity, fluffy and elegant feeling.
Because the linear density of polyester microfiber is much lower than that of conventional fibers, it has different dyeing characteristics from conventional fibers. This is mainly manifested in dye uptake rate, dye uptake, dye uplift, color depth, level dyeing, and dye migration. , Color vividness and dyeing fastness are obviously different from conventional fibers. The increase in surface area caused by low linear density firstly causes an increase in the degree of dye adsorption and desorption during dyeing. The increase in the degree of adsorption leads to an increase in dye uptake, a decrease in wet fastness and light fastness, and secondly, it causes the dyeing of fabrics. The color density is reduced. Improving the dyeing performance of polyester microfibers and fabrics has become a topic of great interest to enterprises. In fact, ultra-fine fiber is a kind of differentiated fiber that has developed rapidly in recent years. It is called a new generation of synthetic fiber. It is a high-quality, high-tech textile raw material. It is a chemical fiber that is in the direction of high technology and high simulation. A typical representative of the development of new synthetic fibers. Superfine fiber, also known as superfine denier. (Denier is the unit of fiber fineness, one gram of silk weighing 9000 meters long is denier, and the unit of fineness of silk is 1.1 denier). Because it is thinner than traditional fibers, it is more fluffy and softer than ordinary fibers, and it can overcome the shortcomings of natural fibers that are easy to wrinkle and man-made fibers are impermeable. In addition, it also has many irreplaceable excellent characteristics such as warmth, no mold, no insects, light weight, and waterproof. The varieties of ultra-fine fibers include ultra-fine denier viscose yarn, ultra-fine denier nylon yarn, ultra-fine denier polyester yarn, ultra-fine denier polypropylene yarn and so on.
