Abstract

The invention discloses a spinning method for blue fibers dyed through indigo plants. The method comprises the steps of opening picking, ultrasonic impurity removal, drying, care, carding, drawing, roving and spinning. The problems of high impurity content, poor spinnability and the like of fibers dyed through plants are solved. The fibers dyed through plants are subjected to ultrasonic impurity removal, dried and cared after being subjected to opening picking in sequence, the content of fiber impurities is reduced, the surface performance of the fibers is improved, the spinnability of the fibers is improved, and finally spinning of the yarn dyed through plants is achieved, wherein the spinning process is smooth, and the yarn quality is high.

Description

technical field

[0001] The invention relates to a spinning method for dyeing blue fibers with indigo plants, belonging to the field of textiles. Background technique

[0002] Bulk fiber dyed spinning generally needs to go through processes such as opening and cleaning, carding, drawing, roving, and spinning. However, a series of problems are encountered when the conventional spinning method is used for color spinning of plant-dyed fibers. During the carding process, plant-dyed fibers are wound around thorns, making it difficult to form slivers; Sticky, clogging the bell mouth; Cot roller winding during roving; Yarn breakage during spun spinning, high blending rate, severe yarn winding and broken ends; Severe dust during the whole spinning process, colored particles adhere to the card clothing and top rollers , Roller.

[0003] The main factor causing the above reasons is the fundamental difference between plant dyed fiber and conventional chemical dyed fiber. Vegetable dy...
