Polyester Spun Yarn Manufacturing Process
The process of spinning fibres into yarn can date back to the Neolithic period, but yarn spinning is the first industrialised process. Until a few centuries ago, spinning was known as the processing of yarn into textiles, fabrics and products, which made up the majority of textiles and fabric products in the United States and other parts of the world.
For comparison, we have compiled a list of yarns made from polyester fibres, polyethylene, nylon, cotton, wool and polypropylene, which are produced using conventional methods. The above methods were carried out using a process that processes polyester, filaments and yarns. The 35: 65 ratio of the spinning yarn was produced in four different spinning systems, namely in the spinning mill.
By repeating the above steps, the folded yarn and spun yarns were directly produced from polyester, filament, wool and polypropylene. The yarn covered was produced in a process that shows the process by which the parts are covered.
One of the conceived constructions that start with the continuous yarn is that other materials such as polypropylene, polyester, wool, fiberglass, nylon and other polyethylene fibers can also be used. The continuous threads and yarns are then joined to form a final product, the polymer yarn or the polystyrene yarn.
Furthermore, the aim of this invention is to provide the spinning yarns mentioned above for the production of polystyrene, polypropylene and other polyethylene fibres. The process of producing the spun yarn in the invention may be used to produce other materials such as polyester, wool, fibreglass, nylon and rigid polystyrene foam. The Japanese patent Open has proposed a method of spinning the yarn made of filament yarn.
In this case, the wetting of the unapplied yarn, drying at low temperatures, drawing the fibre under wet or warm conditions and thermofixed texture are also basic elements of the fibre production process.
When using two strands of individually spun yarn, it is possible to produce a single yarn with improved volume feel by dividing it completely (without the above decay step) or winding it separately. You can also knit the sewn yarn or dye it with raw dye, but you can use both the spun yarn and the filament yarn together. Sewing thread is the heart of the yarn spun - yarn, and there are at most two or more yarns in it. Like any other yarn, you can use a combination of spun and filament yarn as well as a variety of other textures and textures in the yarn.
Non-oriented polyester yarn is subjected to tensile and heat treatment to give the filament weak spots in places and to tear the yarn to obtain a spin - like yarn. The quality of the yarn spun (highly structured yarn or from unspun yarn) can be determined by the following methods as described here.
The final amount of fibre obtained by this method is the same as obtained by the traditional method of knitting or weaving fabrics. Therefore, the yarn obtained by these methods is of higher quality than the yarns obtained by the above conventional methods. The yarn from which knitting or woven fabric is obtained is hampered by the use of two different methods of yarn production, one for knitting and the other for weaving.
On the other hand, many methods have been proposed that give the filament yarn the palpability of the spun yarn. In particular, the present invention relates to a process in which the filaments themselves are essentially broken to such an extent that the surface structure is similar to that of a spinning yarn, corresponding to the appearance and feel of the felt when spinning the yarns. It is also known that a thread made of yarn has undergone so-called "spinning processes" or "treatments" to give mass and structure to this yarn, which will be a well-known art. I have shown that I propose to take naps on the surfaces of filament yarn and also to propose the use of this method for the production of wool, woolen clothing and other fabrics.
The two main constructions of Corespun are polyester filament yarns, which are covered and protected with polyester fibres, and cotton fibres, which envelop and protect them. The filament yarn is made by taking individual polyester threads, grouping, twisting and tangling them to make them work. According to my invention, the yarn material is used in the form of a mixture of cotton, wool, polyester and polyethylene, as well as a combination of other materials. Filament yarns are made in this way by taking individual polyester threads that are grouped and twisted and confused in such a way that they become so confused and confused that they are "functional" and no different.
In the production of polyester staple fibres, the process of melting and melting during spinning and the production of filament yarns is roughly the same as in the production of filament yarns.
