Technical Field

The invention relates to a carpet preparation process, in particular to a moisture absorption loop polyester carpet and a preparation method thereof.

Background

Most of the current carpets on the market have relatively weak moisture absorption function, complex process and high cost except bathroom carpets. Most bath mats on the market are made of cotton yarn, or chenille yarn or woven by a velvet cutting machine. However, although the carpet or the floor mat made of cotton has a strong water absorption function, the material source is unstable, the phenomenon of hair falling and pilling easily occurs due to short fibers, the carpet or the floor mat becomes hard after washing, the comfort level is affected, and the phenomena of dehydration and mildew are not easy to occur. And the cotton type spinning process is complex, the cotton type spinning process needs to be dyed by reactive dyes, the pollution is large, and the color fastness is relatively poor. The existing loop pile carpet has the risk that a user hooks a foot and hooks other objects no matter how the carpet surface layer yarn material is free of a self-twisting function, so that potential safety hazards exist, and meanwhile, dust is difficult to clean after falling into the loop pile of the carpet. In the market, although the bathroom mats made of terylene, such as cut pile carpets, have water absorption, the piles are easy to scatter and bloom after being washed, so that the water absorption is weakened, or the piles are mutually bonded to influence the appearance and the usability, so that the service life is shortened. And the cut pile carpet has poor wear resistance.

Through the search of the existing patent documents, the utility model patent of CN 201165601Y discloses a novel carpet, which is made of chenille yarn with coarse wool, composed of chenille fluff and carpet backing cloth, and the chenille carpet with low wool and coarse wool is made of chenille yarn. However, the chenille yarn has serious feather falling and low spinning efficiency; the yarn cannot be dyed, so that the yarn has limitation and no diversity. In addition, the chenille yarn has complex production process in the spinning process, serious pile hair falling, low production efficiency due to thin core wires, low tensile strength and high yarn breaking frequency in the spinning process and the weaving process, and thus the cost is overhigh.
