Abstract
The invention discloses a sewing thread with a high softening point, wherein the sewing thread comprises polypropylene, poly(4-methyl-1-pentene), an antioxidant and a heat stabilizer. The invention relates to the technical field of fiber textile; and the prepared sewing thread with the high softening point is applicable to the field of textile sewing, has a high softening point property, satisfies various industrial sewing, particularly requirements on high-speed sewing, and effectively solves a recycling difficulty at the same time.
Description
Technical field
The present invention relates to the fibrous woven technical field, particularly a kind of sewing thread and method for making and application with high softening-point.
Background technology
Sewing thread refers in the formed product processes such as clothes, interior decoration, gas support fabric construction and geotextiles, the yarn that different parts is linked together by seam.Sewing thread is widely used in the fields such as industry, agricultural, medical treatment, science and techniques of defence as the main material in the joint technique.As the industrial sewing line that is applied in the industry, the realization of the good and bad abutment joint of its combination property is most important.Along with the rise of fabrics for industrial use, the kind of industrial sewing thread and consumption are also significantly improving, and the industrial sewing product is special because of its purposes, and the performance of sewing thread in the abutment joint technology has also proposed more harsh requirement.
Along with the innovation of textile technology, industry is to industrial sewing thread, particularly the demand of high speed sewing thread also more cumulative adding.After in case sewing velocity improves, repeatedly deflect and and cloth between high-speed friction can bring the larger heat of giving birth to sewing thread, poor heat resistance, the softening point of ordinary sewing line are low, be easy to just occur situation softening even broken string, so the ordinary sewing line can't be competent at the occasions such as at a high speed sewing.Just because of this, current sewing thread shows all the more the restriction of industry.
On the other hand, the kind of current sewing thread is generally terylene, so that all there are significant difference in polypropylene fibre goods and sewing thread in outward appearance, feel, washing, and incompatible on terylene and the polypropylene fibre physical property, prior art becomes a key difficult problem that restricts Polypropylene recovery field to the reclaiming again of Polypropylene of terylene thread sewing.Chinese polyster fibre sewing thread output was 540,000 tons in 2003, quite a few is wherein arranged is to engage for the sewing of Polypropylene, to the Polypropylene discarded object of terylene thread sewing be reclaimed again under the prior art condition, have to rely on a large amount of labours to separate by hand terylene thread and polypropylene fibre goods, could reclaim again the polypropylene fibre goods.Such recovery method is time-consuming, effort; And owing to very easily causing again the unnecessary waste of Polypropylene reclaimed materials and loss in the separation process, this also is that restricting current the key technology difficult problem that Polypropylene reclaims the field.
In sum, at present about the preparation method of sewing thread with high softening-point report is not arranged also.
Summary of the invention
Goal of the invention of the present invention be low for existing sewing thread softening point and with the inconsistent technical deficiency of polypropylene cloth, a kind of sewing thread and method for making and application with high softening-point is provided.
For achieving the above object, the technical solution used in the present invention is:
A kind of sewing thread with high softening-point is provided, and the component of this sewing thread is: polypropylene, poly-4-methyl 1-amylene, antioxidant and heat stabilizer.
