Problems solved by technology

However, using the conventional spinning process, due to the poor spinnability of the copper alginate fiber, the content of the copper alginate fiber in the actual yarn is lower than the design, and the yarn can be spun with low yarn count and poor evenness. From the perspective of yarn process reconstruction and process design, solve the problem of difficult processing of alginate copper fiber and cotton blending, so as to enrich the types of functional cotton yarns, increase the added value of yarn products, and provide technical support and product solutions for the transformation and upgrading of the cotton spinning industry

Embodiment 1

[0021] Embodiment 1: the pretreatment process of alginate copper fiber

[0022] Copper alginate fibers are brittle and broken, and there are problems such as fiber cohesion, low strength, high brittleness, and poor spinnability.

[0023] Conventional practice (such as CN 105012999A) adopts direct blending of copper alginate fiber and absorbent cotton. Although the blended yarn can be endowed with good antibacterial properties, the strength and spinning conditions of the yarn have not been improved. The blended yarn has the antibacterial property of copper alginate fiber, but it does not endow the blended yarn with processability.

[0024] In this example, the copper alginate fiber is pretreated to improve its yarn-forming performance. The main parameters of the copper alginate fiber pretreatment, that is, the health care treatment include additives, water temperature, the ratio of additives to water, the ratio of health care solution to fiber, There are five factors of health...

Embodiment 2

[0047] Embodiment 2: the setting of opening and cleaning, carding process

[0048] Based on the fact that the alginate copper fiber is brittle and broken, there are problems such as fiber cohesion, low strength, high brittleness, and poor spinnability. Conduct experiments to reduce the impact strength of alginate copper fiber and maximize the loss of alginate copper fiber to increase the production rate of alginate copper fiber. The main parameter of the opening and cleaning process is the distance between the impact point and the holding point The main parameters of carding are the height of the cotton feeding board, the speed of the carding part and the speed of the flat board.

[0049] (1) The opening and cleaning process includes: processing the mixed fibers through the plucking machine, the mixing opener, the roller card opening machine, the vibrating cotton feeding box and the single hand lapping machine in sequence. All beaters of roller card opener and single beater l...

Embodiment 3

[0052] Example 3: Processing of 7.29tex cotton / copper alginate fiber 97 / 3 blended yarn for high-grade underwear

[0053] The 7.29tex cotton / copper alginate fiber 97 / 3 blended yarn for high-grade underwear produced in this embodiment uses 6800-7200Nm of raw cotton. The specific implementation process is as follows: the health liquid: alginate copper fiber is treated for 24 hours at a ratio of 1:10, and then mixed with the slivers that have been opened and removed and broken into bales on the bale grabbing machine; The cotton cleaning process adopts a half-grip striking distance, the distance between the striking point and the holding point is 35mm, and the striking speed of the beater of the single beater lapping machine is 720r / min; the carding process raises the cotton board by 12mm; The piece speed is 730rpm for the licker-in roller, 270rpm for the cylinder, and 22rpm for the doffer; the flat plate speed is 70mmpm; the twist coefficient of the roving in the roving process is...

Abstract

The invention relates to a processing method of cotton and copper alginate blended yarn and belongs to the technical field of yarn manufacturing processes. Copper alginate fiber and cotton are pretreated respectively, and after the copper alginate fiber and the cotton are mixed evenly, mixed fiber is sequentially subjected to opening picking, carding, combing, drawing, roving and spinning, wherein the opening picking process comprises the steps that the mixed fiber sequentially passes through a bale plucker, a mixing opener, a roller card wire opener, a vibration cotton feeding box and a single beater scutcher to be treated, the roller card wire opener and all beater screens of the single beater scutcher are sealed; a half holding and beating gauge is adopted, and in the carding process, controllable half-hold licker-in opening is adopted; needle teeth small in working angle and low in density are adopted in carding machine card clothing. When applied to processing of the copper alginate fiber and cotton mixed yarn, the method has the advantages that the mixed yarn is less in hairiness, high in strength, less in nep, good in yarn levelness and the like.

Description

technical field [0001] The application relates to a processing method of cotton and copper alginate blended yarn, which belongs to the technical field of yarn manufacturing. Background technique [0002] Seaweed is a class of ancient low-level green algal plants that live in the ocean. The world's seaweed resources are very rich, with a wide variety of species. It is estimated that there are nearly 10,000 species. At present, there are more than 100 species of economical algae that have been used, including brown algae, red algae, green algae and cyanobacteria. The main algae production areas in the world are concentrated in Asia, especially China, Japan and the Korean Peninsula. The production of these three places has accounted for two-thirds of the total production, and the output value accounts for about 96%. [0003] Sodium alginate, which can be extracted from natural seaweed by acidification or calcification, is used as an important raw material for the preparation o...
