Introduction And Comparative Analysis of Ring Spinning, Air Spinning And Jet Spinning

Give me a minute to tell you the difference between ring spinning, air spinning and jet spinning

Ring spinning

Ring spinning is the most widely used and versatile spinning method in the market. Ring spinning refers to the winding speed of the bobbin is faster than that of the wire ring, and the cotton yarn is twisted to make fine yarn, which is widely used in the spinning engineering of various short fibers. Such as common combing, combing and blending, the wire ring is twisted by the bobbin through the yarn strip to drive the steel collar back, at the same time, the friction of the steel collar makes its speed slightly less than the bobbin. The spinning speed is high, and the shape of the ring spindle yarn is a conical helix that the fibers are mostly transferred inside and outside, so that the fibers are wound and connected inside and outside the yarn. The structure of the yarn is tight, and the strength is high, which is suitable for various products such as thread making and weaving and knitting.

Ring spinning (combing) process:

Clearing -- carding -- pre-banding -- banding and rolling -- combing -- banding -- roving -- spinning -- winding

Ring spinning (general comb) process:

Cleaning -- carding -- combining -- roving -- spinning -- winding

Air spinning

Air spinning without spindle, mainly rely on the comb roller, spinning cup, false twisting device and other parts. The comb roller is used to grab and comb the feed of the sliver fiber, and the centrifugal force generated by its high-speed rotation can throw out the grabbed fiber. Spinning cup is a small metal cup, his rotation speed is more than 10 times higher than the comb roller, the resulting centrifugal effect, the cup of air out; According to the principle of fluid pressure, the cotton fiber enters the airflow cup and forms a fiber flow, which moves continuously along the inner wall of the cup. At this time, there is a yarn head outside the cup, which leads out the fibers of the inner wall of the cup and connects them, and the drilling effect caused by the high-speed rotation of the cup with the yarn tail is like "feeding" the cotton fiber and adding the yarn to pinch, so that the yarn is connected with the fibers of the inner wall of the cup, and the yarn is drawn under the winding tension of the yarn barrel, and the output yarn is continuous to complete the process of air spinning.

Characteristics of air spinning

Air spinning has the advantages of high speed, large yarn roll, wide adaptability, simple mechanism and no spindle, steel collar, steel wire ring, which can double the output of spun yarn.

The difference between air spinning and ring spinning

Air spinning and ring spinning are new textile technology and old spinning technology. Air spinning is air spinning, while ring spinning is mechanical spinning, which is twisted by spindle, steel bell and steel wire ring and drawn by roller. On the other hand, the air spinning is carried by the air flow, and the fiber is held by one end and twisted. Generally speaking, ring spun yarn has less hair, higher strength and better quality. The process of air spinning is short, the raw material is short, the yarn wool, the number and twist can not be very high, and the price is low.

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

Air jet spinning

Jet spinning is a new spinning method which uses high-speed rotating air flow to twist yarn into yarn. Jet spinning adopts cotton sliver feeding, four roller double short rubber ring with large draft, twisting yarn through fixed nozzle. After the yarn is drawn out, it is wound through the cleaner to the yarn barrel and wound directly into the bobbin yarn.

Jet spinning can spin 30-7.4tex (20-80 British) yarn, suitable for pure spinning and blending of chemical fiber and cotton. Because of the special spinning mechanism of jet spinning, the structure and performance of jet spinning are obviously different from ring spinning, and its products have a unique style.

Characteristics of jet spinning and its products:

a, high spinning speed. Jet spinning uses air twisting, without high-speed rotating machinery (such as steel wire rings in ring spinning), to achieve high-speed spinning, spinning speed can reach 120-300 meters/min, and the output per head is equivalent to 10-15 times of each spindle ring spinning.

b, short process flow. Jet spinning is less than ring spinning roving, bobbin 2 processes, saving about 30% of the plant area. Compared with ring spun yarn, 10,000 spindle workers 90 people, reduced by about 60%, machine material consumption is about 30% lower than ring spun, usually maintenance costs and maintenance workload are also reduced.

c, the product quality is good, with characteristics. The quality of air-jet yarn is better than that of ring spun yarn except that the strength of yarn is 5-20% lower than that of ring spun yarn. The physical characteristics of air jet yarn such as CV value, coarse detail and yarn defects are superior to ring spun yarn. The yarn strength is lower, but the strength unevenness is lower than that of ring spun yarn when the yarn is above 3mm. It is suitable for weaving new looms such as rapier loom and air jet loom, and can increase loom production efficiency by more than 2%.

The quality of jet spinning is not only similar to ring spun yarn, but also has its uniqueness, the friction coefficient of jet yarn is large, the yarn has direction, and its friction performance is also directional. Better wear resistance than ring spun yarn, but feel harder.

Jet spinning attached some devices, can also develop some special varieties of yarn, such as fancy yarn, core yarn, mixed yarn and so on.

d, wide variety adaptation. Jet yarn can do both knitting products and woven products, and the variety is widely adapted. More applications are: knitted T-shirt products, uniform and plump cloth, no skew, less strip shadow, less strip dry defects, anti-pilling, cool and permeable, strong three-dimensional sense; Bedding, the use of air yarn dry, stiff characteristics, you can get uniform cloth, feel thick, crisp and breathable effect; Leisure products, such as: double-sided casual wear, sportswear, etc.

According to the characteristics of the jet yarn, it is also possible to develop unique styles of products. For example, the use of jet fabric stiff, rough and other characteristics, it is processed into linen fabric, as well as crepe fabric, wool-like products.

Today, Lenado's TN-I jet loom in the market "a machine is difficult to find", multi-party companies have sought cooperation, orders ushered in explosive growth, shipments continue... With the first intelligent loom manufacturing technology developed by Lenado, while continuously analyzing market opportunities and user needs, constantly upgrading and iterating the loom, we are moving to a higher level of development.
