Breakthrough In Yarn Control For Knitting Denim

In recent years, while developing various kinds of woven denim, China has actively complied with the latest international trend and invested a lot of technical strength and funds to develop knitted denim. However, because of the particularity of indigo blue cheese, it has not achieved the desired result.

The SDJ168 type indigo warp knitting machine developed by Changzhou Dajiang Textile Machinery Manufacturing Co., Ltd effectively conquered the technical difficulties of cheese yarn, and made the yarn problem restricting the development of knitted denim thoroughly solved.

Lin Guangxing, Secretary General of the China knitwear Association, after seeing knitted denim, affirmed that this is the best knitted denim on the surface of fabrics. The success of the indigo warp yarn barrel is a historic contribution to the development of denim varieties.

Denim has always been the darling of the clothing industry since twentieth Century.

It attracts consumers' attention with its bold and unrugged style.

Traditionally, denim is mainly woven by weaving, and the denim made of blue weft and white weft is stiff, firm and thick. The garments made after processing are bold and bold.

But the woven denim is more heavy, air permeability is generally, elasticity is not good, variety is monotonous.

In spite of the fact that woven denim is more ideal, many improvements have been made by the manufacturer, including adding spandex silk to make it flexible.

But many denim enterprises still want to develop knitting denim, thereby increasing the denim variety, making denim more widely used in clothing.

Knitted denim not only has the style of woven denim, but also has unique properties of knitted fabric.

Its texture is fine and clear, soft and comfortable, high elastic and breathable, and rich in variety.

According to the industry, the earliest development of knitted denim is the United Kingdom, but it has not been widely promoted in the market. Until the second half of 2001, Brazil knitted denim was introduced to the US market.

In recent years, many enterprises in our country are committed to the development of knitted denim, but all of them fail.

The main influence on knitting denim fabric is knitting technology, elastic yarn and indigo yarn. The first two items are not a problem at present, but the most important thing is indigo yarn.

Some enterprises have tried many ways to solve the indigo yarn, but they failed because of too long process, serious yarn dyed yarn, large chromatic aberration, too many joints, low volume and low output.

In order to overcome the difficult problem of knitting denim yarn, the Changzhou Dajiang Textile Machinery Manufacturing Co., Ltd., which made the warping machine, absorbed the lessons of other enterprises' failure. According to the characteristics of denim and indigo blue yarn and the requirements of knitting denim technology to yarn, the machine of indigo warp yarn was finally developed by mechatronics.

The equipment is mainly used for weaving the ball yarn dyed yarn of the indigo cowboy warp or pigment dyed on the warp shaft directly and collectively and unwinding into a single cheese yarn for knitting denim weaving.

Wu Yongsheng, senior engineer of China Textile Machinery Association, has seen the manufacturing principle and technology of the equipment. He thinks that the design idea is clear and the degree of mechanical and electrical integration is high. It is a useful attempt to solve the quality problem of indigo yarn.

It is understood that the yarn made of this equipment has been applied in Changzhou Heng Shun knitting factory and Huayu knitting factory in Changzhou Hutang, and has formed the ability to produce knitted denim in batches. At present, the two enterprises have received the first batch of foreign orders.

Shandong LAN Yan group, one of the largest denim manufacturers in China, is also preparing to send the warp shaft to Dajiang textile machinery company to test the indigo yarn.
