Embodiment Construction

[0011] Using polyethylene terephthalate PET and polybutylene terephthalate PBT as raw materials, it is produced according to the following process flow and process conditions: Slice conveying and screening→slice drying→screw extrusion→melt spinning→outer ring blowing Cooling→spinning oiling→winding forming→finished product.

[0012] The process conditions are:

[0013] Specifications: 55dtex / 24f;

[0014] Denier central value: 55 dtex;

[0015] Spinning speed 3800m / min;

[0016] Wind speed: 0.8~0.9m / s;

[0017] Concentration of bamboo oil agent: 10.88~11.1%.

[0018] The physical indexes of the elastic polyester drawn yarn produced by the above-mentioned method are detected as follows:

[0019] project value Linear density (dtex) 55 Linear density deviation (%) 0.21 Breaking strength (CN / dtex) 3.56 Coefficient of variation of breaking strength (%) 1.3 Elongation at break (%) 26 Coefficient of variation of elongation at break (...

Abstract

The invention discloses an elastic polyester drawing yarn, which is characterized in that polyethylene terephthalate (PET) and polybutylene terephthalate (PBT) are compositely spun. The elastic polyester drawing yarn adopts different components with different viscosities to be compositely spun, by utilizing the difference of retraction rate of boiled water, the yarns are automatically coiled, so that the fiber has high elasticity; when the elastic polyester drawing yarn is used on a home textile fabric, the elastic polyester drawing yarn has advantages of high feeding rate, fineness, softness, good drapability, good ventilation, strong water absorption property and good wrinkle resistance; and the production process is simple, no burr and no flying filament are produced, and the production cost is greatly reduced.

Description

technical field [0001] The invention relates to a polyester yarn, in particular to an elastic polyester drawn yarn. Background technique [0002] At present, the high-performance product market in the decoration and home textile market is still occupied by developed countries. Although the output of my country's chemical fiber industry is huge, the proportion of high-tech and high value-added products is relatively small, and even high-end chemical fiber products still rely heavily on imports. Imported products are often expensive and belong to high-end consumption, which cannot be afforded by the majority of consumers. Since the appearance of elastic polyester draft yarn, its performance has the advantage of being comparable to imported products and its price is lower than that of imported products. It can completely replace imported products and is favored by consumers. However, the stretching of elastic polyester in the prior art [0003] The comprehensive characterist...
