Detailed analysis of pearl fiber knitted fabric

Pearl fiber fabric is a new type of fiber fabric. It uses high-tech means to add nano-level pearl powder into the fiber during viscose fiber spinning, so that nano-pearl particles are evenly distributed inside and outside the fiber, which has the unique skin care of pearls. Function and anti-ultraviolet function, and has excellent moisture regain, comfortable hand feeling and wearing performance, suitable for making high-end underwear and other personal clothing. In fact, pearl fiber fabrics and non-woven fabrics have the same properties in some aspects. Now we will introduce the functional characteristics of pearl fiber knitted fabrics. The raw material of pearl fiber fabric is mainly regenerated cellulose fiber, and the finished fabric should not be folded and packaged, and should be packaged in rolls. When softening the pearl fiber fabric, the air permeability and moisture conductivity of the fabric must be considered, and hydrophilic softeners should be used as much as possible. Due to the low bursting strength of pearl fiber fabrics, the process principle of'high concentration and short time' should be grasped when carrying out biological enzyme treatment. When dyeing, the temperature increase of fabric dyeing should master the principle of slow first and then fast to reduce the production of colored flowers. In addition to fine washing, the fabric blended with Tencel or Modal should also be pre-formed. In the dyeing and finishing process, the pre-treatment of the cotton-containing pearl fiber fabric only needs to use fine washing (or scouring). Regarding the control of the weaving process, the temperature, humidity and speed of the weaving workshop should be well adjusted, and attention should be paid to keeping the knitting needles intact. Pay special attention to the uniformity of the tension control of the yarn tension. The hairiness index of the yarn has a great influence on the finish of the final fabric. Knitted fabrics based on regenerated cellulose fibers are prone to clouding, so yarn uniformity is very important. When designing high-end fabrics, the uniformity, neps, details, joint strength and yarn hairiness of the yarn must be controlled. In the production process design of product development and the control of each link, attention should be paid to the following key points. The bursting strength of underwear must be above 180cN according to the conservative design, and the products blended with Tencel or modal should have at least level 3 or above in anti-pilling resistance. At present, the main domestic development of underwear fabrics is the blending of pearl fiber with Tencel, Modal, and cotton. The blending ratio is mainly 40/30/30 and 30/70. The main ingredient of pearl particles is calcium carbonate, plus amino acids and trace elements, so pearl fiber has stronger alkali resistance than viscose fiber. The coloring rate of pearl fiber is similar to that of viscose fiber, so when blending or interweaving is used, attention should be paid to the coloring rate of mixed fiber and interwoven yarn. If spandex is not used in the development of underwear fabrics, attention should be paid to the stability of the fabric size. The weight of the fabric should not be too low, and should be controlled at about 200 g/m2. The content of pearl fiber should not be less than 30%, so that the developed fabric has a higher cost performance. When designing and developing pearl fiber underwear fabrics, we should pay attention to the following three principles. The development of pearl fiber yarns and fabrics mainly adopts blending methods, which can not only give full play to the functional characteristics of pearl fibers, but also solve the weakness of low strength of pearl fibers.
