Description
Technical Field
The invention belongs to the technical field of spinning, and particularly relates to the field of cashmere blended weaving.
Background
The cashmere product has the unique style of comfortable wearing, strong warmth retention, plump suede, soft hand feeling, soft luster and smoothness, is deeply favored by consumers, and the demand on the market is continuously increased. However, cashmere resources are in short supply, so that the cashmere is expensive. Therefore, besides pure cashmere products, a large number of blended products with high quality and low price emerge in the market, and the requirements of people on cashmere textiles are met to a certain extent.
Rabbit hair is a protein fiber which is used earlier by human beings, has excellent color and luster, fiber fineness and length, good heat retention and fluffiness, smooth handfeel and good comfort, gives people a full and elegant feeling, and is lower in price compared with a wool fabric, so that the rabbit hair fabric is popular with consumers. The rabbit hair fiber in China is rich in resources, white in color, long and thin, fluffy and soft, smooth and elastic. The reasonable development and utilization of rabbit hair resources can alleviate the defects of cashmere resources and improve the added value of products. On the other hand, rabbit hair also has certain inherent defects, and the cohesive force between rabbit hair fibers is poor, so that the spinning difficulty is increased. Because the cohesive force between the fibers is small, the rabbit hair fabric has serious hair loss compared with other hair fabrics. Another drawback of rabbit hair is that the breaking strength of the fiber is poor, it is easy to break during spinning, and the service life of the fabric is greatly reduced.
The plasma technology just solves the defect of poor cohesion of rabbit hair fibers. The application of plasma technology in textile begins in the 50 th of the 20 th century, and the research on plasma treatment of textiles begins in China from the 80 th of the 20 th century. The water absorption of the cotton fiber can be obviously improved by plasma treatment. After the fibrilia is treated by the plasma, the colloid on the surface of the fibrilia is decomposed, and more hydrophilic groups are formed on the surface of the fibrilia, so that the dyeing property of the fibrilia is greatly improved. The surface friction coefficient of the wool fiber can be effectively increased after the wool fiber is subjected to plasma treatment, the fiber strength can not be reduced, and therefore the cohesive force and the spinning performance of the fibers during spinning are improved. The surface modification of materials by plasma technology has been widely appreciated and applied. The rabbit hair fiber is modified by low-temperature plasma, and the surface of the rabbit hair fiber is mainly subjected to activation and etching treatment, so that the surface of the rabbit hair fiber is roughened, the cohesive force between the fibers is increased, the crimpness of the rabbit hair fiber is improved, and the advancing angle and the retreating angle of the rabbit hair fiber are reduced, so that the processability and the wearability of the rabbit hair fiber are improved. The rabbit hair raw material in the high-spinnability rabbit hair and the blending product thereof developed by the project is the fiber raw material processed by the plasma technology.

In the technical scheme, preferably, in production, the temperature is controlled to be between 10 ℃ and 30 ℃, and the humidity is controlled to be between 65% and 75%.
In the above technical solution, preferably, the humidity is controlled at 70%.
In the above technical scheme, preferably, in the step a, low-temperature plasma modified rabbit hair fibers with fineness of 13.9 μm, fiber length of 49mm and moisture regain of 16.4% are selected, cashmere fibers with fineness of 15.6 μm, fiber length of 31.5mm and moisture regain of 16.9% are selected, and the two fibers are mixed to form a blend fiber in percentage by mass, wherein the low-temperature plasma modified rabbit hair fibers account for 80%, and the cashmere fibers account for 20%.

In the above-described aspect, preferably, in step E, the speed of the two-for-one twisting is 6500 rpm, the twist is 250T/M, and the twist direction is "S".
The invention selects rabbit hair fiber and normal cashmere fiber treated by plasma technology as raw materials, and adopts specific technological parameters to spin 2/26Nm high-grade knitting yarn with special performance. The innovation of the invention is that: the rabbit hair fiber treated by the plasma technology is selected as the raw material, so that the defects that the traditional rabbit hair fiber is poor in cohesive force, the product is difficult to produce in the spinning process, the spinnability is poor and the like are overcome.
Because rabbit hair fiber is low in strength and poor in fatigue resistance, the rabbit hair fiber is easy to damage and break under the action of violent machinery, the short fiber rate is increased, the spun yarn has serious fly hair falling, the yarn strength is poor, and the broken ends of the spun yarn are increased. Therefore, on the premise of ensuring the raw materials to be fully mixed, the number of the fiber blending machines is reduced as much as possible, and the fiber is prevented from being severely loosened and damaged. In addition, the rabbit hair fiber has strong hygroscopicity, the direct moisture absorption of the fiber easily causes felt and agglomeration, and an indirect oil adding method is generally adopted to avoid oil and water from being directly sprayed on the rabbit hair fiber when blending oil. However, as the proportion of the rabbit hair fiber is high (such as 80%), the effect of uniform oiling can be achieved, and only water can be directly added to a part of the rabbit hair. In order to avoid the rabbit hair directly adsorbing excessive oil and water to form felt and bundle, and the rabbit hair is added with oil in several times.
The carding process is one of the most critical processes in the whole spinning process. Although the cohesive force between the rabbit hair fibers is improved after the rabbit hair fibers are treated by the plasma technology, the rabbit hair fibers have low strength, so that the speed of the rabbit hair fibers is properly reduced during carding, and the speed ratio between rollers is reduced. It is suitable to use low speed, small speed ratio and mild carding technology. The drafting effect is the key to influence the evenness of the yarn in the spinning process, and because the surfaces of the rabbit hair fibers are smooth, the cohesive force is poor, the slippage among the fibers is large, although the cohesive force is improved after the treatment of the plasma technology, the drafting multiple is smaller than that when 100% cashmere is spun in order to prevent the yarn from generating coarse details due to the overlarge drafting of the fibers. In the subsequent production process, attention should be paid to the tension of the yarn. The tension is as low as possible under conditions that ensure good formation of the bobbin.
The workshop temperature and humidity have great influence on the normal production of high-proportion rabbit hair blended products, particularly the humidity, and in order to prevent the hair net from generating wave phenomenon and rabbit hair from flying, the temperature is generally 20-30 ℃ and the humidity is preferably 65-75% in the workshop temperature and humidity control. And when the temperature is more strict, the relative humidity of air is strictly controlled to be about 70%, the temperature is higher than 10 ℃ in winter, and is lower than 30 ℃ in summer.
Compared with the prior art, the blended yarn woven by the method increases the application range of cashmere blended products, improves the added value of cashmere products, simultaneously selects the rabbit hair fiber treated by the plasma technology as the raw material, overcomes the defects of poor cohesion of the traditional rabbit hair fiber, high production difficulty of the products in the spinning process, poor spinnability and the like, and has better spinnability in the production process of the products.
