Description

Technical Field

[0001] The present invention relates to the field of yarn processing, and more particularly to a processing technology for ice-cold imitation cotton yarns. Background Art

[0002] With the improvement of people's living quality, the demand for fabric functionality has gradually increased significantly. While pursuing aesthetics, people's demand for comfort has also been rising. Keeping warm in winter and cool in summer has always been an eternal theme of consumer demand, which is particularly prominent in the field of fibers and fabrics. With the continuous development of cool-sensation fabrics, polyethylene has recently become a key material for cool-sensation fabrics, and there has been an increasing amount of research on the modification of polyethylene.

[0003] However, the dyeing of existing polyethylene materials is rather perplexing, with significant differences in performance compared to traditional materials, and there are also other defects. Summary of the Invention

[0004] The purpose of the present invention is to provide a processing technology for ice-cold imitation cotton yarns, which solves the problem of dyeing existing polyethylene materials, and at the same time endows the yarns with cotton-like feel, wear resistance, light weight, and cool-sensation performance.

[0005] To solve the above technical problems, the present invention is realized through the following technical solutions:

[0006] A processing technology for ice-cold imitation cotton yarns includes the following steps:

[0007] S1: Mix modified polyethylene chips, masterbatch, and additives, and then extrude them through an extruder to obtain 75D - 300D colored polyethylene yarns;

[0008] S2: Wind up the colored polyethylene yarns through a winding device;

[0009] S3: Mix and wind at least two colored polyethylene yarns, and then perform air texturing through an air texturing machine to obtain ice-cold imitation cotton yarns;

[0010] S4: Oil the ice-cold imitation cotton yarns and wind them up.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0012] In the present invention, by adding masterbatch and mixing it with modified polyethylene chips for original pulp coloring, the subsequent dyeing process is reduced, and at the same time, the existing dyeing difficulties are solved. Moreover, through air texturing by an air texturing machine, the cohesion and weavability of the yarns are improved, so that the yarns can have a cotton-like feel, be more wear-resistant, and lighter in weight.

[0013] As a preferred technical solution of the present application, in S3, the model of the air texturing machine is TMTA3S, and 3 - 5 nozzles are used.

[0014] As a preferred technical solution of the present application, in S3, when the air is deformed, the conduction speed of the colored polyethylene yarn is 280 - 300 meters per hour, the humidity is 60% - 80%, and the temperature is 15 - 30 °C. The quality of the yarn produced under such conditions is stable.

[0015] As a preferred technical solution of the present application, in S3, the number of colored polyethylene yarns is 2 - 10. In this way, multiple colored polyethylene yarns can be held together to improve the wear resistance.

[0016] As a preferred technical solution of the present application, in S2, the winding speed of the winding device is 2800 - 3000 meters per hour.

[0017] As a preferred technical solution of the present application, in S4, a spray method is used to coat vegetable oil on the imitation cotton yarn. In this way, the saturation performance of the yarn can be improved, making it softer and smoother, and effectively improving the wear resistance.

[0018] As a preferred technical solution of the present application, in S4, the concentration of the vegetable oil is 25 - 50 g / L, and the oil content is 0.7% - 1.0%.

[0019] As a preferred technical solution of the present application, in S1, the additives are antistatic agents and melting agents. The ratio of modified polyethylene chips, masterbatch, and additives is 97%:2.5%:0.5%. In this patent, the melting agent can be selected as silica powder to increase the viscosity of the spinning solution, avoid fiber breakage, and form a strong internal structure through the interaction with the molecules of the spinning material, thereby improving the stability of the material.

[0020] As a preferred technical solution of the present application, in S1, the extruder is a screw extruder, the extrusion pressure is 8 - 18 kg / MPa, the temperature is 210 - 330 °C, and the extrusion speed is 80 - 120 kg per hour.
