Embodiment 1

[0019] A kind of kapok bulk fiber spinning pretreatment process, the steps comprise:

[0020] A. Immerse the kapok loose fiber with a smoothing agent for 15 minutes. The smoothing agent is a modified silicone oil smoothing agent, specification XT-01, and the manufacturer is Wuhu Xunteng New Material Co., Ltd.;

[0021] B. Pre-dry the impregnated kapok loose fiber at 55°C for 80s until the water content reaches 5.8%;

[0022] C. Low-temperature plasma treatment is carried out in oxygen atmosphere plasma; the parameters of low-temperature plasma treatment are: discharge time is 40s, and discharge power is 30KW.

[0023] A kapok pure spun combed yarn, using the above-mentioned kapok loose fiber pretreated by low-temperature plasma, after cleaning → carding → pre-doubling → coiling → combing → head-doubling → double-doubling → three-doubling → roving→ Spinning → post-processing and other traditional processes, kapok pure spun combed yarn has 266 twists and 21 fineness.

Embodiment 2

[0025] A kind of kapok bulk fiber spinning pretreatment process, the steps comprise:

Abstract

The invention relates to a pretreatment process for spinning of kapok loose fibers. The pretreatment process comprises the following steps of impregnating with cyclopentasiloxane, prebaking to remove water, and carrying out low-temperature plasma treatment. The pretreatment process has the advantages that the low-temperature plasma treatment is carried out on the kapok fibers, so that the hydrophilic performance and the apparent morphology of the fiber material is improved, the technical advantages of saving water and energy are realized, the environmental pollution is less, and the operation is simple and is easy to control; the treatment with low-temperature plasmas on the kapok fibers only reaches the depth about 10nm from the surface of the fibers, on the premise of not damaging the self performance of kapok, the structure activity of a waxy outer layer of the kapok fiber treated by plasmas is changed, the hydrophilicity is enhanced, the appearance takes on etching morphology, the interfibrillar cohesive force is enhanced and the spinning is easy.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a spinning pretreatment process of kapok loose fiber. Background technique [0002] my country is rich in kapok fiber resources, kapok fiber is the fruit fiber of woody plants, because its fiber hollowness is as high as 80%. The cell wall is thin, the length is short, the rigidity is strong, and the specific gravity is very light, so it is difficult to form a yarn. However, kapok fiber has ultra-fine and soft characteristics. The fabric made of kapok is as soft as cashmere. In addition, its dyeability is the same as that of cotton. It also has good moisture absorption, antibacterial, non-mildew, and hollow warmth Performance, is a very promising textile raw material. [0003] Because the surface of kapok fiber is waxy, water-repellent, the density is only 0.29g / cm 3 , Poor cohesion. The current technology makes it difficult to spin or add too much adhesive before...
