Processing Technology And Characteristics Of Semi Worsted Yarns

< p > in recent years, the domestic a target= "_blank" href= "http://www.91se91.com/" > strong > clothing < /strong > /a > textile enterprises continue to explore the market, continue to forge ahead in the semi worsted field, and are also committed to the introduction of more advanced semi health worsted yarn.

At present, many enterprises have introduced advanced production equipment and production technology. When processing these yarns, some good and healthy fibers have been added, which effectively improves the poor toughness of < a target= "_blank" href= "http://www.91se91.com/" > strong > material < /strong > / a >.

< p > according to tradition, woolen engineering has three systems: woolen, worsted, semi worsted, and so called semi worsted is a spinning project between worsted and woolen fabrics.

But this argument can be explored.

The so-called semi worsted between the worsted and the worsted, in fact, it means that the length of the semi worsted material is shorter than the worsted spinning, and it is not that the semi worsted yarn is a bit like the rough spinning, and the worsted is a bit like the worsted.

In fact, the earliest semi worsted fabric is actually a worsted fabric, but it is a simplified and incomplete spinning project.

With the progress of technology, the concept of semi worsted fabric has changed correspondingly. The original simplified worsted system not only uses wool raw materials, but also uses cotton based materials, and originally used Woollen Spinning equipment, and now uses cotton wool mixing equipment or even whole cotton spinning equipment. Therefore, from the situation of raw materials and equipment, semi worsted has evolved into a spinning system between cotton spinning and worsted spinning. Raw materials are similar to cotton spinning, cotton and wool blending, and the style of products is similar to that of worsted fabrics.

< p > common semi worsted yarn < a target= "_blank" href= "http://www.91se91.com/" > strong > textile > /strong > /a > procedure: wool and wool woollen carding machine carding strip -- three ~ four way combed wool spinning roving wool spinning yarn.

It is obvious that the textile engineering is actually a simplification of worsted spinning, eliminating the part of worsted knitting.

Data show that this spinning route is aimed at some wool with less grass content, mainly for wool production.

But this process has some fatal weaknesses.

If the wool top is omitted, the semi worsted system must use other means to control the content of raw materials in the raw material, control the short wool content in raw materials and improve the carding effect of the top, which is originally belong to the top making process.

Practice has proved that only by changing the equipment and changing the process, although it has some effect, it is not very ideal.

Under such circumstances, the only way is to choose raw materials. Besides the length and fineness of raw materials, special requirements are also made for raw materials containing less grass, less short hair and so on.

Obviously, such semi worsted fabrics are not competitive.

There is also a form of semi worsted process that is more concise.

< p > because the semi worsted fabric has no general special bar making system, so the combing of the fibers is not very sufficient, and the rigidity and curl of the wool fiber are larger than that of the cotton, so the semi worsted spinning high count yarn is relatively difficult.

Therefore, a unit uses three stripes to reduce the unevenness of the sliver and improve the straightness of the fiber in the sliver, one of which is also equipped with a self leveling device.

Some units also use some crafts of wool spinning, such as slippery drafting, such as paying attention to the reasonable selection of rear zone drafting.

< p > any spinning system is equipped with equipment according to the requirements of the product. Obviously, it is wise to use this system for spinning coarse fiber yarn. This semi worsted only requires output, so the wide comb carding machine has been used as raw material for wool, cashmere and other fibers as animal fibers. Most of them are woolen spinning raw materials, but with the development of the market, the demand for finer and lighter demands has emerged, and the woolen products can no longer meet the needs of the market.

Its length is close to the length of cotton fiber, and the impurities in raw materials are relatively small. The main products of these fibers are mostly knitted velvet, and do not need to be polished and clean like worsted fabrics, so the advantage of semi worsted fabric is beginning to show.

But semi worsted is no longer a simplified worsted fabric, but a spinning system between wool spinning and cotton spinning.
