Description

A high-count alpine animal fiber blended yarn textile

technical field

The invention relates to a blended yarn textile and its production process, more precisely, a high-count animal blended yarn textile and its production process.

Background technique

With the growth of economy, the development of science and technology, and the continuous improvement of living standards, people not only require beautiful and fashionable clothes, but also pay more attention to the comfort and health care and environmental protection effects of clothing materials.

In textile production, yarns and products spun from conventional animal fibers have a certain degree of warmth retention and comfort, such as cashmere. Cashmere fiber enjoys the title of "fiber gem" because of its softness, lightness, softness, slipperiness and waxy characteristics. Famous, but what cannot be ignored is that the raw material cost of pure cashmere products is high. A cashmere goat produces 50-80 grams of plush per year, and the cashmere of every five goats is enough to make a cashmere sweater on average.

As one of the alpine animal fibers, yak velvet has smooth texture, strong warmth retention, high fiber strength, corrosion resistance and low cost. Yak wool is harvested once a year, and the annual wool production of adult yaks is 1.17-2.62 kg; young cattle The weight is 1.30-1.35 kg, of which coarse hair and fluff each account for half. Yak cashmere is very thin, with a diameter of less than 20 microns and a length of 3.4 to 4.5 cm. It is irregularly curved, and the scales are tightly entangled in a ring shape, with soft luster and strong elasticity. The development of yak wool is economical and environmentally friendly. Its fluff falls off naturally, and herdsmen only need to pick it up. At present, my country can recycle 4,000 tons of yak cashmere raw materials every year.

High-count animal fiber is a new type of textile fiber, which includes alpine animal hair, such as yak hair, camel hair, mink hair and so on. Different from traditional textile fibers, it has its own advantages and characteristics. After blending it with chemical fibers such as nylon and viscose, or cellulose fibers such as tencel and hemp fiber, it has better performance in terms of hand feel, elasticity and warmth retention. Both are superior to high-grade cashmere, and the cost is much lower than cashmere. The yarn has the characteristics of environmental protection, wear resistance, warmth retention and comfort. It has a strong substitution effect on some expensive raw materials in the market. very promising. The blended yarn obtained after blending with other fibers is in great demand in the market.

The preparation of a low-cost, environmentally friendly, wear-resistant, warm-keeping or comfortable blended yarn, and the use of the blended yarn to prepare textiles will surely achieve greater market application value.

Detailed ways

The best production process for high-count animal fiber blended yarn is: raw material delivery, loose wool dyeing, oiling and wetting, wool blending, cleaning and blending, carding, drawing, roving, spun yarn, winding, doubling, Two-for-one twisting, reverse twisting, packaging and storage.

The following is an introduction to the above-mentioned part of the process, and the part not introduced is the same as the conventional production process.

1. The high-count animal fiber first adopts the pretreatment step: the pretreatment step includes: soaking, stretching and setting; the soaking process includes: soaking the animal fiber in the soaking solution for 30 minutes, and the composition of the soaking solution is: NaCl200g/L , acetic acid 1mol/L; the setting process includes: put the stretched animal fiber into the setting solution and soak for 4 minutes, then take it out and dry it. The components of the setting solution are: NaCl200g/L, sodium hypochlorite 5g/L.

The above-mentioned pretreatment has changed the problems such as the uneven thickness of the single fiber and the easy breakage that often occurs in the subsequent stretching and spinning process. After the above pretreatment, compared with untreated animal fibers, the fiber thickness after stretching is more uniform, the overall length increases by more than 18%, and the fineness changes by more than 10%.

Second, refueling and moistening:

After the high-count animal fiber is dyed with loose wool, the strength of the fiber decreases, and the original oil and antistatic agent of the fiber are washed away. Due to the floating color after dyeing, the surface of the fiber is astringent and difficult to draw. In order to make the spinning process go smoothly, wool oil and antistatic agent can be added, and wet treatment can be carried out, so that the high-count animal fiber and the chemical fiber blended with it can maintain a suitable moisture regain on the machine.

The preferred method of adding oil to wet pretreatment: take 1.3% by animal fiber weight and crude oil, mix crude oil and water in a weight ratio of 1:8, use a sprayer after mixing to evenly spray on high-count animal fibers in a flat and straight way Put it on, put it on the machine after 24h. Take the antistatic agent at 0.6% of the weight of the chemical fiber or cellulose fiber, mix the antistatic agent with water at a ratio of 1:10 by weight, spray evenly on the chemical fiber or cellulose fiber from the sprayer in the same way, put it on the machine after standing for 24 hours.

3. Combing

The problems that usually exist in the carding process are: winding cylinders, floating ends of the cotton net, easy broken ends, and a large proportion of hair loss due to fluff damage. Therefore, the technical points of the carding process are to determine a reasonable moisture regain on the machine and follow the machine process to reduce fiber damage. , Reduce the entanglement and kneading between fibers, and realize the principle of smooth fiber transfer. The preferred treatment method is: the moisture regain on the machine is strictly controlled within the range of 16%. If the moisture regain is too large, it will easily entangle the cylinder and doffer. If the moisture regain is too small, it will easily generate static electricity and increase fiber nodding.

Four, drawing

The problems that usually exist in the production process of the drawing process are: the static electricity of the mixed wool top is high, it is easy to wrap around the top roller, there are many end breaks, and life is difficult. The preferred treatment method is: reduce the speed of the front roller, control the delivery speed at about 120m/min, install a static eliminator device and other measures.

5. Roving

The problems that usually exist in the roving process are: around the top roller, it is easy to produce coarse details, and the production efficiency is low. In order to solve the problem of roving quality, the preferred treatment method is:

1) Strengthen the maintenance of the top roller aprons, shorten the acid treatment of the top rollers and the cleaning cycle of the aprons, and ensure that the surface of the top roller aprons is smooth and smooth.

2) The roving twist is set to be too large.

3) Reduce the speed of the roving spindle and control it at about 500r/min, and the speed of the front roller at about 180r/min.

4) The drafting cradle ensures consistent pressurization, and the pressure is set to be biased.

5) The humidity in the workshop is strictly controlled within the range of 72%.

Six, spun yarn

The usual problems in the spinning process are: due to the poor cohesion of the roving, the broken ends of the spun yarn are high, and the consumption is large. The preferred treatment method is:

1) The spindle speed is controlled at about 7000r/min.

2) Twist coefficient should be mastered on the basis of ensuring product style requirements, and the twist coefficient of this batch of yarn is 90.

The yarn prepared by the above-mentioned technology is soft and can be used to spin underwear, and can be worn next to the body, comfortable, and has good air permeability. The knitting of underwear has been changed from the original flat knitting machine to the circular knitting machine, which greatly improves the superior quality of the underwear. And because of its low cost, it can partially replace high-grade and expensive cashmere. Broaden the consumer groups, to meet the majority of consumers' pursuit of cashmere products. This kind of functional, environmentally friendly, fashionable, high-end and moderately priced products are more attractive to consumers and have broad market prospects.

The above is only a specific implementation of the present invention, but the scope of protection of the present invention is not limited thereto, and any changes or replacements that do not come to mind through creative work shall be covered within the scope of protection of the present invention.
