Introduction to core spun thread:

Polyester staple fiber is coated with polyester high-strength filament. 

It has a natural feather appearance of polyester staple fiber, and it is different from ordinary short fiber threads that have a strong pull force, which is 1.75 times that of ordinary threads. 

The shrinkage rate is lower than the normal SP thread. It is a core line popular in the West such as Europe and the United States. 

Since this thread is not easy to break in the 5000 rpm high-speed needle car, it is widely used by high-quality manufacturers. 

Liqi brand polyester core spun thread is a domestic brand. The parameters of the Liqi core spun thread are comparable to those of the British and American brand core spun threads. It can be replaced and the price is quite affordable. 

As this product is the main advantage of our factory, plus many years of production experience, the product maturity is high, widely used in denim clothing, bookings, handbags, leather goods and children's wear.

"Liqi" card core spun thread is covered by cotton or polyester staple fiber polyester long fiber, through the spinning process resulting in single yarn, and then two or more single yarn through the double twist into a thread. 

The long fiber part of the core accounts for 60 % of the overall thread size, so the tension is more than 1.75 times that of the SP thread. 

The surface of the core line is hairy, which helps to reduce the reflectivity and enhance wear resistance. 

When the high-speed car seam or washing friction, the performance of core spun thread is particularly prominent and is widely used in European, American and foreign denim garment companies.

Divided into: Poly-poly core spun thread and cotton-poly core spun thread two.

The polyester package core spun thread: The appearance is the same as the SP thread. 

The bread has imported polyester filament, which is currently the sewing thread used by the cowboy. 

The characteristics of the core line are that the washing will not be as hairy, broken, and contracted as the ordinary SP thread.

Cotton package polyester package core spun thread: The pure cotton thread used outside is imported polyester filament, which is a core sewing thread used in cowboy materials. 

It is characterized by the characteristics of both cotton thread and high-strength water-resistant washing.

In order to improve production efficiency, many garment companies have high-speed needles that reach speeds of more than 5,000 rpm per minute. Ordinary SP threads can not withstand high heat or pull threads, so the ideal sewing thread is to use polyester core spun threads.

Our production base is located in Guangdong, the cost of production and manufacturing is much lower than the United States and the UK or Hong Kong counterparts, many brand garment units in the past two years and established a good cooperative relationship.

As my company in the domestic intervention core spun thread earlier, production capacity is very mature. 

The core spun thread is also one of the superior products of our company. 

All the specifications on the market can be produced by our factory(from 8 to 60 2, 3, and 4 shares).

Pure cotton wrap spun yarn thread 42 cotton wrap spun yarn thread 42 rotten yarn thread used for yarn thread, core spun yarn thread generally with strong and elastic synthetic fiber filament as the core spun thread, outsourcing cotton, wool, adhesive fiber and other short fibers Together twisted and spun yarn thread.

The core spun yarn thread has the excellent performance of both filament core spun yarn thread and outsourced short fiber. 

The more common core spun yarn thread is polyester core spun yarn thread, which uses polyester filament as the core spun yarn thread, outsourcing cotton fiber.

There is also a spandex wrap core spun yarn thread, which is made of spandex filament yarn thread, outsourcing yarn thread made of other fibers. Knitted fabric or jeans made from this core spun yarn thread are comfortable and flexible when worn.

At present, cotton is used as the skin, and the core spun yarn thread of polyester staple is widely used. It can be used to produce student clothes, work clothes, shirts, bathrobe fabrics, skirt fabrics, sheets and decorative fabrics. 

In recent years, an important development of core spun yarn thread has been the use of core spun yarn thread of polyester core coated with sticky fiber, sticky fiber and linen or mixed with cotton and sticky fiber in women's clothing fabrics, as well as cotton and silk or cotton and wool. 

Mixed coated core spun yarn thread, These products are very popular with people.

Current spinning process for polyester cotton wrap spun thread

Comb system:

Cotton: A clear flower is combed with one head of cotton and-roving-fine yarn thread (core).

Comb system:

Cotton: a clear flower a comb a roll of cotton and a fine comb one after and two together with a triple-gauze-fine sand(core).

In the actual processing process, the selection of the core spun thread process should be determined by the requirements of yarn thread formation and the number of spinning branches. 

The general principle is that if you can use a comb, you do not need a comb. 

If you want to use a comb system, the process can be shortened. 

Shorten to reduce production costs. For example, some manufacturers combed the cotton strips thousands of unevenness rate, fiber straightness and line degree are better, after a joint can meet the requirements of the coating. Then, its process can adopt:

Cotton: A clear flower is combed with a cotton roll and a fine comb and-roving a fine yarn thread (core).

After the number is selected, the mixing ratio can be calculated according to the calculation formula(calculation formula slightly), such as the production of 11.8 Tex(50s) polyester cotton yarn thread as an example, 

The actual blending ratio of its yarn is: 49.36 % for polyester and 50.64 % for cotton;

The calculated data is very close to the actual production. However, when designing a worn-out flower fabric with a core spun yarn thread blending ratio, the proportion of cotton should be greater. 

One is the comfort of the fabric, and the other is to increase the three-dimensional sense of the fabric after the worn-out flower pattern. 

Such as 23.62 Tex(25s) cotton/polyester blending ratio: 66.7 / 33.33; 11. The ratio of 14 Tex(53s) cotton/polyester blends is: 52.35 / 47.65 and so on. The spandex filament in the elastic core spun yarn thread is generally used 15 % -20 % mixing ratio to meet the requirement of elastic elongation of 35 % of the high elastic fabric in the latitude, and it is also conducive to improving the strength of the core spun yarn thread.

Determination of spinning coefficient

The strength of the core spun yarn thread decreases with the increase of the twist coefficient, which is because the strength of the filament decreases with the increase of the twist coefficient. 

When the cotton content is less than 50 %, although the strength of the outsourced short fiber increases with the increase of the twist coefficient, the former plays a major role, so the yarn thread twist coefficient of the core should be low. 

However, the polyester cotton yarn thread used for rotten flower fabrics can not be too small, and it is generally controlled at about 304-333, so as to avoid the filament of rotten flowers. 

The twist coefficient of the spandex yarn thread is 20-30 higher than that of the same variety(referring to fine yarn thread or weft yarn thread) and the same number of ring ingot cotton yarn thread, making the two yarn thread strong.

The 42 sheets, bedspreads, pillowcases, sofa covers, curtains, tablecloths, and other supporting front bedding and interior decoration products are ideal. Textile.

The core spun thread has the characteristics of good external fiber permeability, good hygroscopicity, easy to start static electricity, no lifting, not easy to melt, easy to dye, soft feel, and high strength of core spun yarn thread fiber, good elasticity, undetermined model, wear-resistant acid and alkali resistance, etc.. 

Suitable for spinning wide range, yarn thread strength, uniform dry, less feathers, and can be used for high quality fiber wrap cheap fiber, reduce costs, can prevent good performance

The spinning range is wide, the process flow is short, the production efficiency is high, the spinning core spun yarn thread structure is stable, the sliver is uniform, the feathers are small, and the loose degree number is not used. 

In the spinning process, because the filament has not been twisted, it has never been twisted. 

So the spinning is more likely to maintain the strength from the core.

The rotten flower bag core spun yarn thread, after a special printing process, in addition to the short fiber back surface is translucent, three-dimensional pattern, widely used for decorative cloth, such as curtains, table cloth, bed cover and so on.
