Description
Technical Field
The invention relates to the technical field of blended yarn production, in particular to a production process of cashmere and seaweed fiber blended yarn.
Background
The cashmere fiber is soft, fine, comfortable and good in heat retention, and the product is a symbol of high-grade textiles. The thinning of cashmere products is the development direction of the high-end cashmere products, and the grade of the products depends on the thickness and the quality of yarns. During the production process of semi-worsted and worsted fine pure cashmere yarns, the semi-worsted fine cashmere yarns have slight hair falling and have a velvet type feeling but are lack of body bones; the worsted fine yarn has luster and good drapability, but the skeleton is too soft, and the plain weave fabric has pirn silk marks and chicken claw marks occasionally; the slub yarn has strong velvet type feeling, has a skeleton and has no obvious visible defects on the surface.
The seaweed fiber is extracted and purified from natural seaweed, belongs to renewable resources, has various seaweed types, more than 2500 types in the world, is used for manufacturing the fiber from brown algae, red algae, green algae, blue algae and the like, and contains substances such as protein, mineral substances, amino acids, various vitamins and the like required by human bodies. The alginate fiber is processed by wet spinning, is mainly used for medical dressings, such as medical alginate gauze which contacts wound exudate to form hygroscopic gel, so that the wound is kept moist, the wound is promoted to be quickly healed, and the alginate fiber has very obvious curative effect on treating the wound and skin ulcer inflammation, is widely applied internationally, and has good biocompatibility, high moisture absorption gel forming property, high oxygen permeability and biodegradation absorptivity.
The alginate fiber has flame retardant property, Limit Oxygen Index (LOI) is more than or equal to 45 percent, basically no smoke is generated, no toxic gas is generated, no molten drop is caused to flow, and the performance is superior to that of the flame retardant fiber on the current market. And no flame retardant additive is added, so that the problems of flame retardant falling, physical property reduction and the like are solved. The alginate fiber applied to the field of textile clothing has excellent moisture absorption performance as a clothing material, the moisture regain exceeds 16 percent, the comfort is comparable to that of a high-grade long staple cotton fiber material, and the alginate fiber has excellent hand feeling and wearing comfort similar to silk. The alginate fiber applied to the field of biomedicine can absorb a large amount of wound exudates, reduce the times of changing bandages and the nursing time, and reduce the nursing cost; the seaweed medical fiber is in contact with the exudates to generate gel swelling, and a large amount of exudates are fixed in the fiber to prevent the immersion phenomenon. After calcium ions in the biomedical alginate fibers are exchanged with sodium ions in blood, the coagulation and incrustation rates of the blood are accelerated; meanwhile, the fiber absorbs exudate and then swells to form soft gel, so that the protective effect on the new tender tissue is achieved; the fibers can be rinsed with warm saline to prevent secondary trauma during gauze removal. The alginate fiber has excellent antibacterial performance, the antibacterial rate of escherichia coli reaches 99%, and the antibacterial rate of staphylococcus aureus reaches 99%. The performance of the alginate fiber for preventing electromagnetic radiation is obviously superior to that of the conventional viscose fiber. The alginate fiber molecules can be used as ion fabrics for preparing electromagnetic shielding fabrics because macromolecules can be chelated with polyvalent metal ions to form stable complexes. The reason may be that the electromagnetic shielding and antistatic capabilities of the fabric are improved when the ion content in the fiber matrix is increased to a certain extent. The alginate fiber is obtained from natural plant components, has biocompatibility and degradability, fundamentally solves the environmental protection problem after the material is used, and cannot cause harm to the environment.
The yarn formed by blending the cashmere fiber and the alginate fiber is not reported, and how to prepare the cashmere and alginate fiber blended yarn which can combine the advantages of the cashmere fiber and the alginate fiber becomes a problem to be solved.

After pre-drawing, the mixed sliver is made by a two-pass drawing frame. The quantitative ratio of the cashmere strips and the seaweed fiber strips is the same, and the drawing adopts 4 strips: drawing was performed at a ratio of 4.
And (3) head combination: combining 8 pieces, wherein the minimum distance of the roller surface is 11mm multiplied by 16mm, the total draft multiple is 7 times, the sliver-out speed is 220m/min, and the half-cooked sliver ration is 25g/5 m;
and thirdly: combining 8 pieces, wherein the minimum distance of the roller surface is 12mm multiplied by 26mm, the total drafting multiple is 8 times, the sliver-out speed is 370m/min, and the cooked sliver ration is 25g/5 m.
In the step S4, stretching the hybrid into a roving with a roving machine; rear zone draft multiple of the roving frame: 1.32; roller gauge length: 12mm × 25mm × 40mm, ingot speed: 700 r/min; twist factor: 75.
in the spun yarn of the step S5, a spindle spinning frame is adopted to make the spun yarn; the draft ratio is 1.45-1.52, the twist of the prepared spun yarn is 460 twists/10 cm, and the fineness of the spun yarn is 26 Nm.
Further, the method also comprises the following steps of cabling: and (3) carrying out doubling twisting on the two cashmere and seaweed fiber blended yarns prepared in the fine process, wherein the twisting direction of the doubling twisting is opposite to that of the single yarn. The cabling twist was 230 twists/10 cm.
Example 2
The production process of the cashmere and seaweed fiber blended yarn related by the embodiment comprises the following steps: preparing S1 cashmere strips, preparing S2 seaweed fiber strips, drawing S3, roving S4 and spinning S5.
In the preparation of the cashmere strip of step S1, the cashmere fibers are subjected to wool mixing and carding to form the cashmere strip. In the step, the wool blending is to uniformly spray the wool blending auxiliary agent on the cashmere fibers, uniformly stir the wool blending auxiliary agent, and tightly seal the wool blending auxiliary agent for 20 to 24 hours; the wool additive accounts for 15% of the total weight of the fiber.
The wool additive is evenly mixed wool oil, an antistatic agent, protease, dioctyl sodium sulfosuccinate, amino silicone oil, sodium chloride and deionized water. The dioctyl sodium sulfosuccinate used can improve the permeability and the emulsifying foamability, and can remarkably reduce the surface tension of water so that the chemical auxiliary agent can better permeate into cashmere to improve the wool blending effect. The sodium chloride can further improve the permeability of the dioctyl sodium sulfosuccinate, so that various auxiliary agents can be more easily carried into the cashmere fibers, and the wool blending effect is improved.
Further, the antistatic agent at least comprises one of polyoxyethylene stearate, polyoxyethylene ketone laurate and polyoxyethylene nonyl phenyl ether. Polyoxyethylene stearate is selected in this example.
Further, the wool additive comprises 30-40 parts by mass of wool oil, 10-15 parts by mass of antistatic agent, 5-10 parts by mass of protease, 5-10 parts by mass of dioctyl sodium sulfosuccinate, 5-10 parts by mass of amino silicone oil, 5-8 parts by mass of sodium chloride and 100 parts by mass of deionized water. Specifically, in this embodiment, the wool additive includes 35 parts by mass of wool oil, 10 parts by mass of an antistatic agent, 5 parts by mass of a protease, 5 parts by mass of dioctyl sodium sulfosuccinate, 5 parts by mass of aminosilicone oil, 8 parts by mass of sodium chloride, and 100 parts by mass of deionized water.
In the step S2, the alginate fiber strip is prepared by opening picking and carding machine. The alginate fibers have poor resilience, are smooth and loose, are easy to deposit between needling in the cotton carding process, are difficult to transfer and are easy to wind a cylinder, so the speed of a licker-in and the cylinder is reduced, the speed of the licker-in is controlled at 850r/min, the speed of the cylinder is 300r/min, and the technological principles of tight spacing, strong carding, low speed, light weight, multi-carding and light beating, less damage and multi-row defects are implemented.
In the step S3 drawing, the cashmere strips and the alginate fiber strips are prepared into mixed strips through a pre-drawing machine and a drawing machine; controlling the humidity of the workshop between 65 and 70 percent; in the prepared mixed sliver, the cashmere fiber accounts for 50% of the weight of the mixed sliver. After pre-drawing, the mixed sliver is made by a two-pass drawing frame. The quantitative ratio of the cashmere strips and the seaweed fiber strips is the same, and the drawing adopts 4 strips: drawing was performed at a ratio of 4.
And (3) head combination: combining 8 pieces, wherein the minimum distance of the roller surface is 11mm multiplied by 16mm, the total draft multiple is 7 times, the sliver-out speed is 220m/min, and the half-cooked sliver ration is 25g/5 m;
and thirdly: combining 8 pieces, wherein the minimum distance of the roller surface is 12mm multiplied by 26mm, the total drafting multiple is 8 times, the sliver-out speed is 370m/min, and the cooked sliver ration is 25g/5 m.
In the step S4, stretching the hybrid into a roving with a roving machine; rear zone draft multiple of the roving frame: 1.32; roller gauge length: 12mm × 25mm × 40mm, ingot speed: 700 r/min; twist factor: 75.
in the spun yarn of the step S5, a spindle spinning frame is adopted to make the spun yarn; the draft ratio is 1.45-1.52, the twist of the prepared spun yarn is 440 twist/10 cm, and the fineness of the spun yarn is 48 Nm.
Further, the method also comprises the following steps of cabling: and (3) carrying out doubling twisting on the two cashmere and seaweed fiber blended yarns prepared in the fine process, wherein the twisting direction of the doubling twisting is opposite to that of the single yarn. The cabling twist was 220 twists/10 cm.
Comparative example
The comparative example is prepared by mixing cashmere fiber according to the weight ratio of 50: 50, adding wool oil, and carrying out carding, slivering, roving and spinning processes to obtain the yarn with the fineness of 26 Nm.
The yarn quality tests were carried out on the blended yarns prepared in examples 1 and 2, and the test results are shown in the following table:
the test results show that the prepared cashmere polylactic acid blended yarn has a good yarn forming effect, and the prepared blended yarn completely reaches the FZ/T71006-2009 cashmere knitting yarn standard and reaches the first-class yarn standard.
The foregoing detailed description of the preferred embodiments of the invention has been presented. It should be understood that numerous modifications and variations could be devised by those skilled in the art in light of the present teachings without departing from the inventive concepts. Therefore, the technical solutions available to those skilled in the art through logic analysis, reasoning and limited experiments based on the prior art according to the concept of the present invention should be within the scope of protection defined by the claims.
