Embodiment Construction

[0006] Raw material characteristics: Table 1 shows the physical indicators of modal fibers; Table 2 shows the physical indicators of colored cotton fibers from two origins used by the factory in different periods. It can be seen from Table 2 that the micronaire value of colored cotton is low, and the length difference is large. During production, attention should be paid to rationally adjusting the gauge, reducing blows, and controlling the growth of the short-staple rate; Need to go through the combing process. Since modal fiber and colored cotton fiber are prone to pilling, in addition to optimizing the process parameters, the siro spinning process is also used to improve the quality of gauze and the style of cloth surface.

Abstract

The invention relates to a cospinning spinning technology with the Modal fiber and color cotton belonging to the spinning technology field, comprising the following working procedure: opening, carding cotton, combing, sliver lap, drawing, roving, yarn, cheese winding, the front four working procedures are independent aiming at the Modal fiber and color cotton respectively, the rest working procedures are combined into a common working procedure, the whole working procedure adjusts and improves the parameter and condition of the technology according to the property of the two raw materials, including: a plucker, an opener, and a lap former which are in the opening working procedure; a cotton feeder in the carding cotton working procedure; a drawing frame, a lap former, and a combing machine which are in the combing working procedure; the drawing working procedure adopts a triple drawing and the Rolla Gauge, the roving and yarn working procedures is adjusted through the Rolla Gauge. The invention offsets the disadvantage of the raw material through the improvement to the processing technic, the final yarn has good intensity and uniformity, the fabric feels smooth, the color is natural, which is an ideal environmentally friendly products.

Description

technical field [0001] The invention relates to a blended spinning process of modal fiber and colored cotton in the technical field of spinning. Background technique [0002] Modal fiber is a main wet modulus fiber. The wet strength of this fiber is much higher than that of ordinary viscose fiber. It combines the advantages of natural fiber and man-made fiber. The raw material is natural wood, which can be biodegraded quickly. It is a "green" fiber that meets environmental protection requirements. Modal fiber is silky and smooth. It is a natural mercerized fiber. The fabric feels soft, comfortable and smooth to wear, and has a silky luster. Its product characteristics are shown in Table 1. The color of natural colored cotton is soft and elegant, and the color can gradually deepen after washing. The texture is softer than ordinary cotton. Traditional chemical dyes are not used for dyeing during processing, so it does not contain harmful substances such as formaldehyde, and i...
