The Development Of Vortex Spinning Products In China Is Urgent.

　　 Vortex spinning (VORTEX) It is a free end spinning equipment developed on the basis of jet spinning. It has been widely recognized in the field of cellulose fiber and chemical fiber blending. Vortex spinning is a new textile method directly feeding the sliver into yarn. The equipment uses the eddy generated by compressed air to converge the tip of the fiber to the center of the yarn, and the middle and back part of the fiber is wrapped around the front end of the back fiber, thus forming the vortex spinning yarn. The highest spinning speed of Murata vortex spinning machine No.861 can reach 450 m / min, and its output can reach 20 times of ring spinning and 3 times of air spinning. At present, only Japan Murata produces vortex spinning equipment worldwide. More than 1000 swirl spinning equipment has been sold around the world, mainly in Turkey, South Korea, China, Thailand, Indonesia, the United States and so on, and there are more than 100 in China. Jet vortex Do spinning Because of its high yield, high efficiency and high quality products, it has been widely recognized by spinning enterprises, and there are still some areas to be perfected.

Vortex spinning has excellent Performance

The jet vortex spinning equipment has the advantages of high production, less labor and integrated process. Taking 40 spinning 100% combed cotton yarn as an example, output of 265kg/ hours, eddy spinning only requires 11 workers, and ring spinning Requires 25 workers. The function and fashion of vortex spinning are also very prominent. Vortex spinning has the characteristics of moisture absorption, quick drying, air permeability, Mao Yushao, anti pilling, washing resistance, abrasion resistance and deformation. The unique spinning method gives the vortex spinning line various excellent characteristics, making it the most suitable material for casual wear, and many clothing brand manufacturers that are leading the global market are using vortex spinning to develop products with higher added value. At present, the number of spinning spun yarns in China is generally between 20 British branches and 60 British branches, and the spinning of high count yarn needs to be explored.

Cellulose fiber products are highlights.

Theoretically, the jet vortex spinning machine is suitable for all kinds of raw materials, and its textile properties are different according to different materials. Generally, the yarn length can be made of various yarns below 38 cm, but it is still difficult to produce fibers with small elastic force, which are not easy to enter the air vortex. At present, the most successful market development is cellulose fiber products. Cellulose fiber itself has some excellent properties of natural fiber, but cellulose fiber itself is very soft and bony, and the technology of jet vortex spinning can make up for the defects of fiber and can also play a special role in anti cellulosic properties of cellulose fibers.

When jet spinning equipment is used for processing cotton fiber, it has high requirements for cotton fiber characteristics. High grade cotton is needed, the fiber length is longer and the short fiber content is less. Short cotton fiber length and high short linen content will lead to obvious loss of fibers and poor abrasion resistance of fabrics.

Vortex spinning has wide application area.

The vortex spun yarn has a strong feel, good finish, good surface finish, good brightness and good anti fuzzing and good sphericity. The developed polyester vortex spinning line is most suitable for sportswear. Vortex spun yarn is mainly used in woven products in the following ways. One is imitation hemp products, the fabric is full of appearance and strong handle; two is bedding, the fabric is of good evenness; the three is clothing products, mainly used for sportswear; in knitted products, the vortex spinning line can be used for T-shirts in spring and summer, the fabric feels smooth and comfortable, and it can also be used for towel products, which has good moisture absorption and quick drying properties, and can also be used to weave knitted sweaters. Eddy spinning is also suitable for velvet fabrics, which can give full play to the fluffy structure of eddy spinning and less hairiness.

Product development expects innovation

The eddy spinning equipment, Murata, has been selective in its sales. After opening the Chinese market in 2009, the sales situation is very optimistic. They are mainly distributed in Zhejiang, Shandong and Jiangsu. Vortex spinning itself has distinct characteristics, such as moisture absorption, quick drying, no deformation and less hairiness. However, because jet spinning is a new type of spinning technology, there are a limited number of products in China, and its products are not familiar with many spinning, weaving, dyeing and garment enterprises, nor are they familiar with market developers and product designers. Therefore, there are still some deficiencies in downstream product development. Although the United States has the largest number of equipment, but because the United States is concerned about its high output and less employment, it has not made much progress in product development. Recently, Donghua University and several large home textile enterprises in China have cooperated in developing vortex spinning home textiles products, hoping that some new achievements will come out soon.

Industrial chain collaboration is the key

The emergence of any new fiber or yarn will take a long time to explore the product development. This requires textile enterprises and scientific research departments to explore and work together with the technicians, product designers and marketers. For this reason, the experts gave two suggestions.

First of all, we should increase publicity and popularization of air-jet vortex spinning, expand publicity and popularization of basic knowledge and product application, and expand the influence. It is suggested that the textile industry association take the lead in organizing some seminars and so on, so that more enterprises can understand the performance and use of the air jet spinning, and join the product development team to explore the development of the vortex spinning technology and the direction of product development.

Secondly, we need to develop products around the needs of the future. The end point of any technological development is the product. The yarn is only an intermediate product. Its development must rely on the downstream enterprises such as garments and home textiles. Therefore, we must find out the location of the product, understand what products should be made, and know who the users are, so that we can better promote the development and application of the products. It is best to follow the direction of products that have been successfully developed abroad, give full play to the characteristics of vortex spinning, and develop new products with unique style that ring yarn can not match.

Although the development of vortex spinning is still in its infancy, there are still problems like this, but its advantages are unquestionable. As a new spinning method, jet vortex spinning has attracted more and more attention from enterprises, industry leaders and scientific research institutions. With the increasing cost of labor, vortex spinning with less labor will become an important direction of yarn development in the future.
