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
The present invention relates to a kind of terylene thread, relate in particular to a kind of elasticity polyester drawn yarns.
Background technology
At present, decorate, that premium quality product market is spun on the market by family is still shared for developed country.Although China's chemical fibre industry output is huge, high technology content and high value added product proportion are less, even high-end fiber product serious dependence on import still.Imported product is often expensive, belongs to high-end consumption, and non-consumers in general can bear.Since the elasticity polyester drawn yarns emerged, relying on performance itself to have can the price lower with relative imported product with the advantage that imported product compares favourably, fully can import substitutes, deeply be subjected to consumers in general's favor.But elasticity drafted polyester of the prior art
The overall characteristic of silk is strong not, still can not satisfy the requirement of expensive goods.
Summary of the invention
The present invention is just in order to overcome above-mentioned deficiency, technical problem to be solved provide a kind of feel fine and smooth soft, drapability is good, good permeability, have water imbibition, wrinkle resistance and elastomeric polyester drawn yarns.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is as follows:
A kind of elasticity polyester drawn yarns, it adopts polyethylene terephthalate PET and polybutylene terephthalate PBT to carry out composite spinning.
Above-mentioned elasticity polyester drawn yarns adopts following technological process production: section transport, sieving → chip drying → screw extruding → melt spinning → outer-ring ventilation cooling → spin finishing → coiling and molding → finished product.
The finish that adopts in the described spinning process is this finish of bamboo.
Wind speed during described outer-ring ventilation cooling is controlled to be 0.8m/s～0.9m/s.
Beneficial effect: elasticity polyester drawn yarns of the present invention adopts the component of different viscosities to carry out composite spinning, utilizes the difference of boiling water shrinkage, and automatic curled makes fiber have high elasticity; The advantages such as be on the textile fabric, have upper probability high, feel is fine and smooth soft, and drapability is good, and good permeability absorbs water strong, and wrinkle resistance is good; Production technology is simple, can not produce lousiness, the silk that wafts, and greatly reduces production cost.
The specific embodiment
Adopting polyethylene terephthalate PET and polybutylene terephthalate PBT is raw material, according to following technological process and process conditions production: section transport, sieving → chip drying → screw extruding → melt spinning → outer-ring ventilation cooling → spin finishing → coiling and molding → finished product.
Process conditions are:
Specification: 55dtex/24f;
Fiber number central value: 55 dtex;
Spinning speed 3800m/min;
Wind speed: 0.8～0.9m/s;
This finish of bamboo finish allotment concentration: 10.88～11.1%.
Adopt the physical index of the elasticity polyester drawn yarns of said method production to detect as follows:
| Project | Numerical value |
| Line density (dtex) | 55 |
| Line density deviation (%) | 0.21 |
| Fracture strength (CN/dtex) | 3.56 |
| The fracture strength coefficient of variation (%) | 1.3 |
| Extension at break (%) | 26 |
| The extension at break coefficient of variation (%) | 5.3 |
| Oil content (%) | 1.0 |
As known from the above, this elasticity polyester drawn yarns adopts the component of different viscosities to carry out composite spinning, utilizes boiling shrinkage
The difference of rate, automatic curled makes fiber have high elasticity, has simultaneously fine and smooth soft, the advantages such as drapability is good, good permeability, water imbibition is strong, wrinkle resistance is good of feel.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics, its objective is to allow to be familiar with these those skilled in the art and can to understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.All equivalents that Spirit Essence has been done according to the present invention or modification all should be encompassed within protection scope of the present invention.
