PRODUCT CENTER The products are divided into fiber and terminal products, three major classes of eight series of hundreds of varieties, including 7s-120s, various kinds of cotton blended yarn products; industrial grade, food grade and medical grade pure chitosan fiber series products.
Open-end spinning

Classification:Yarn Products

Species:Open-end spinning

Characteristic:Air spinning is a new spinning technology which uses air flow to condense and twist yarn into high speed spinning.

Application field:With the continuous improvement of technology, the airflow yarn is more and more close to the characteristics of ring spun yarn. Today, yarn has become the preferred yarn for denim, knitted underwear and many other products.

Air spinning is a new spinning technology which uses air flow to condense and twist yarn into high speed spinning.

 

What is air spinning

The utility model is mainly composed of a plurality of components such as a carding roller, a spinning cup, a false twisting device, etc.. The carding roller is used for grasping and carding the feed sliver fiber, and the centrifugal force generated by the high speed rotation can be used for throwing out the fiber. Spinning is a small metal cup, his score of comb roller rotation speed more than 10 times higher, the centrifugal effect resulting from this, put the glass in the air discharging outwards; according to the principle of fluid pressure, the cotton fibers into the air cup, and the formation of fiber flow along the inner wall of the cup in constant motion. At this time, there is a glass yarn, bring out the inner wall of the glass fiber, and connected, plus a cup with a drilling effect produced by the high speed rotation of the yarn tail, just like "hello" side of the cotton fiber, yarn side pinching the yarn, and the inner wall of the cup drawing in fiber connection that tension bobbin, continuous output yarn continuously, to complete the process of rotor spinning.

 

        

 

Technology

Czech EMS-INVENTA (Investa) in the 1969 ITMA exhibition in Basel, Switzerland, recommended air spinning technology to the market, its production capacity is far higher than that of ring spun yarn, but the air air spinning technology to produce the first feeling is very rough, it is difficult in many applications up to expectations.

However, with the continuous improvement of technology, the yarn is more and more close to the characteristics of ring spun yarn. Today, yarn has become the preferred yarn for denim, knitted underwear and many other products.

 

Characteristics of air spinning

The present invention has the advantages of high speed, large volume, wide adaptability, simple structure and no need of spindle, steel collar and steel ring.

 

        

 

The difference between air spinning and ring spinning

Air spinning and ring spinning is a new type of textile technology. Air spinning is a kind of air spinning, and ring spinning is mechanical spinning, which is made up of spindles, steel rings and steel rings. The air spinning is the way of conveying the fiber by the end of a twist. Generally speaking, ring yarn hairiness is more than airflow spinning, high strength, good quality. Air spinning short process, less hairiness protruding, especially the viscose fiber is more obvious, do not break the fiber yarn, but many are wrapped around the fiber yarn hairiness on the body, so the rotor yarn has less hairiness, fineness and twist is not high, the price is low.

From the structure of the yarn, ring spinning is relatively tight, and the airflow is relatively fluffy, rough style, suitable for denim fabric, air spinning yarn is generally rough.
