Description

Multi-fiber variety compact siro spinning production line capable of recycling waste

Technical Field

The utility model relates to a spinning technical field especially relates to but the inseparable match twine spinning production line of multi-fiber variety of cyclic utilization waste material.

Background

The acrylic fiber is soft and light in weight and good in heat retention, but due to poor hygroscopicity and poor wear resistance of the fiber, the phenomena of static electricity and pilling are serious in the using process, and the body feeling comfort level and the appearance effect are influenced. The double-resistant acrylic fiber is a modified acrylic fiber, has the functions of fuzzing resistance and pilling resistance, can be spun or blended, has better wearing effect compared with the common acrylic fiber, and is an ideal fabric for manufacturing thermal underwear for children and old people.

Silk is a pure natural animal protein fiber and is called fiber queen by people. The silk is rich in amino acid components and proteins similar to those of human skin. Its structure and composition are different from other fibre, and it not only has the characteristics of light weight, flexibility, toughness, lustrousness and cleanness, but also has strong hygroscopicity. Air permeability, abrasion resistance, wrinkle resistance and flame resistance. Especially the 'silk fibroin' component in the structure has good beautifying and moistening effects on human skin. The product made of the silk material and the filler can freely perspire the skin, keep the skin clean and make people feel comfortable. The silk fiber has strong moisture absorption and moisture removal functions, and the silk is rich in various amino acids required by human bodies. The silk is soft and elastic in hand feeling, and the surface of the refined and degummed silk is smooth, uniform, smooth and elegant. The 'hydrophilic side amino acid' in the silk has an ultra-strong moisture-removing function (the moisture-removing force is 1.5 times of that of cotton), so that the silk becomes the only natural fiber capable of preventing the silk from changing. Spun silk is derived from silk, is natural protein fiber, is a high-grade textile raw material all the time, is thin and soft, smooth, rich in elasticity, good in luster, strong in hygroscopicity, soft and comfortable to wear, and meanwhile, the silk is complex in components, contains various amino acids beneficial to a human body, can improve the activity of human cells when contacting human skin, has good skin-friendly performance, and is beneficial to the health.

Although the modal fiber has good air permeability and water absorption, and has the softness of cotton, the luster of silk and the smoothness of hemp, the modal fiber is easy to deform, the cost is higher than that of common cotton, and the wear resistance is poor. The double-resistant acrylic fiber has the performance similar to wool, but the elasticity is much better than that of the wool, and the rebound rate can be kept to be about 65% under the condition of 20% elongation. The acrylic fabric is made of artificial chemical materials, can be made into artificial products, and has high cost performance, and certainly has certain disadvantages. For example, acrylic fabrics cannot be directly worn next to the skin, and are comfortable without natural materials. In addition, although the acrylic clothes can be molded strongly and designed into fashionable shapes more freely, the acrylic belongs to short fibers, and the short fibers are easy to pilling. Therefore, the acrylic fabric with poor quality has small pompon after long-term use and is hard to see, and a plurality of acrylic sweaters are mixed with part of wool at present to prevent pilling. Spun silk has the defects of easy shrinkage, unstable size and the like after washing, and the spun silk fiber has high static electricity and poor fiber cohesion and is difficult to form a net into strips independently. The formed yarns have poor quality due to large differences of properties such as dry breaking strength, dry breaking elongation, volume specific resistance, moisture regain and the like of modal, double-resistant acrylic and mulberry silk fibers, so that the yarns blended by three raw materials are not available in the market.

In addition, in the prior art, spinning produces a large amount of waste materials, an automatic and full recycling method is not obtained, and waste is large.

The beneficial effects of the present embodiment are as follows.

1. The price of spun silk fiber is 27 ten thousand per ton, and the price of fine denier Modal fiber and double-resistant acrylic fiber is 20 percent higher than that of the conventional same-grade raw material. By blending the three fibers with different performances, the respective performance advantages of the three fibers are brought into play, and advantage complementation is achieved. The process combines the advantages of compact spinning and siro spinning, and the compact siro spinning has the advantages of high single yarn strength, uniform yarn levelness, compact structure, good wear resistance, less hairiness, bright and clean yarn and the like, and has the style of strand yarn and the attribute of single yarn. The compact siro spinning has obviously improved indexes compared with common ring spinning, can also improve the weaving efficiency in the subsequent process, reduce the sizing amount of the yarn, reduce the environmental pollution in the desizing process, cancel the singeing process and the like.
