You may have heard about that our clothes are made of nylon material, but there are several types of nylon materials that can be used to many industries. If you want to have a general idea of this or you are looking for conventional nylon yarn. Read on this article of three mainly types of conventional nylon yarn, you will get what you want.



Partial Oriented Yarn (POY)


Nylon partially oriented yarn, which is commonly known as nylon POY, is produced from the melting and extrusion (melt spinning) of the PA6 chip. During the spinning process the filaments are stretched or drawn as much as five times their original size to orient the polymer to meet the desired evenness, strength, shrinkage, and elongation properties. Therefore the term partially oriented yarn refers to multi-filament that is only partially stretched. POY is generallylower strength (3.7-4.0Cn/dtex) and larger elongation (about 65-72%) when compare with fully oriented yarn (FDY). 


POY bears the characteristics of excellent thermal stability, excellent light resistance, good mechanical properties and excellent surface cleanliness. For these advantages, POY has been widely used in many fields, for example, it is mainly used in texturizing to make textured yarn andcan also be used in draw warping for weaving and warp knitting of fabrics.


POY


Drawn Textured Yarn (DTY)


Drawn Textured Yarn (DTY) yarn is obtained fromNYLON POY after texturing process on the texturing machines. During texturing, pre-oriented yarn (POY) is permanently crimped using friction. As a result, elasticity and heat retention are increased; the yarn receives a pleasant handle, while thermal conduction is simultaneously reduced.


For its good yarn evenness, light fabric and anti-pilling,DTY yarn is mainly used as a part of weaving and knitting of fabrics for making garments,apparel, home textiles, home decorations, automobile seat covers, bags and numerous different things.


DTY

Fully drawn Yarn (FDY)


It is produced by a process similar to POY manufacturing, but the FDY yarn is produced at even higher spinning speeds coupled with intermediate drawing integrated in the process itself, which allows stabilization through orientation and crystallization. It has stable physical performance. Elongation is about 44-49%; strength>4.2Cn/dtex.


FDY bears the same advantages of POY. The main use of nylon FDY is for stocking, knitting, weaving fabrics, weaving looms and hocovering machines. Also it can be knitted or woven with any other filament yarn to get fabric of various different varieties. It is mainly used in Home Furnishing Fabrics, Fashion Fabrics, Denim, Terry Towel and other.
