The influence to weaving brought from textured yarn brings(1)

Textured yarn(DTY)is featured much of specification, which cause a large difference on physical properties, apparence,dyeing,unwinding performance,thus, in order to have the best weaving effect it is necessary to choose suitable DTY according to different weaving requirement.

The machines apply to DTY are Hydraulic loom, air-jet loom, circular machine, warp knitting machine.Some of DTY used as weft and warp yarn,some needs to be starched,steamed,twisted.It needs to be rewinded,dyed than weaved in Yarn-dye industy, new special requirement emerge in endlessly. The end fabrics made by DTY are circular machine fabrics such as shorn-pile, napping, polar,fleece; rapier loom decoration fabrics such as jacquard weaving;Normal fabrics such as denim fabrics;knitting fabrics such as Cutting velvet, shorn-pile, mesh, flat knitting machine fabrics such as knitting wear; narrow stripe fabrics

This article is about the influence to weaving brought from physical properties,dyeing performance,apparence and unwinding performance of polyester DTY

1. Influence of Polyester DTY's physical properties on weaving

1.1 liner density 1.1.1 the influence of linear density Liner density,also fineness,stand for fiber's thickness.Linear density was decided according to gram weight of fabrics.Take 167 dtex/48 f as an example,the linear density according to international

Application	Non-circular machine	Circular machine	Tolerance
Fineness/dtex	162-167	167-172	±3

1.1.2 adjustment method of linear density 1.1.3 There are two ways of adjustment:first is adjust POY's linear density;second is adjust draw ratio of texturizing. Take 167 dtex/48f as example,,the adjustment and influence can be refered to the table 2.

Draw ratio	Fineness/dtex	Tensile Elonation/%	Apparance
1.78	162	17	Broken filament
1.74	164	20	Normal
1.70	167	22	Normal
1.66	169	24	Normal
1.63	173	27
