Method for producing PP silks and PP bottom double-layer carpet

Abstract

The invention discloses a method for producing PP silks and a PP bottom double-layer carpet. The method is characterized in that polypropylene and master batch are prepared into a PP silk finished product through mixing, heat melting, tensioning, water cooling, silk cutting, heat drawing, net opening, heat setting, cold setting, winding, heat setting, splicing and combining. The PP bottom double-layer carpet consists of felted yarns, warp yarns and weft yarns and is characterized in that the weft yarns adopt the PP silks, and the PP silks are synthetic fibers consisting of linear macromolecules of saturated fatty hydrocarbon of isotactic polypropylene. The fibers do not absorb moisture; the strength is high, and particularly the strength after soaking is not reduced; the yarns have even dryness; and the chemical stability is good. The carpet produced by the invention has a stable structure, does not produce size change due to factors such as self woven structure, outside temperature and humidity, regional environment difference and the like, does not cause the phenomenon such as shrinkage and deformation, bubbling, corrosion and the like, does not need maintenance, and has the advantages of long service life, attractive appearance, good using effect and economization of resources such as manpower, materials and the like.

Description

Technical field: [0001] The invention relates to a carpet, in particular to a non-deformable and long-lasting PP-bottom double-layer carpet and a production method for PP silk. Background technique: [0002] As we all know, carpet, as a soft floor covering, has a long history of development. With the development of science and technology, there are more and more types of carpets. Among them, the double-layer Wilton carpet with hemp bottom is the main variety of machine-woven carpets, and its application is the most widely. The yarn is spun from high-quality pure wool, wool plus nylon, wool plus polyester, etc. The warp yarn is 16Ne / 4 polyester-cotton worsted yarn, the ratio of polyester is 80%, cotton is 20%, and the weft yarn is 350tex×3 jute yarn. [0003] The production method is as follows: velvet yarn winding, hanging, threading, and reeding; then warp warping, shafting, threading, reeding, weft hanging, and weft storage preparation; then start weaving; finally weave t...

AI Technical Summary

Problems solved by technology

[0005] There are problems in the above-mentioned prior art: the structure of the carpet is unstable, and after paving, it will have dimensional changes due to factors such as its own weaving structure, external temperature and humidity, and regional environmental differences, resulting in shrinkage, deformation, and foaming of the carpet, and frequent maintenance. If it is not completely cured, it will not only affect the appearance and use effect, but also consume a lot of manpower, material resources and other resources
