The so-called polypropylene colored yarn is a fiber produced by color-matching the masterbatch and pulling it up to a desired color by melting.

The color fastness and light fastness of polypropylene colored yarn are really very good. No matter whether it is black or red, it can reach 5 grades. And the depth and brilliance are unmatched by post-dyeing methods.

Polypropylene is a hydrophobic fiber, so conventional dyeing is basically useless. By grafting the hydrophilic group to the polypropylene, it is then dyed directly with the dispersion. However, the technology has not completely broken through. If the polyester and polypropylene intertwined fabrics are dyed in the same bath, the depth of polypropylene is probably only about one-fifth that of polyester. If it is hard to dye the dyeable polypropylene, the color fastness in dark colors is rather poor, probably only two. level.

Because polypropylene is low-temperature type, the spandex used must also be low-temperature type spandex, and now 130-degree low-temperature type spandex, when it is scheduled, it does not need to be so hot. Similarly, nylon elastic fabrics can also use 170-degree spandex instead of destructing the nylon amino group at a high temperature of 190 degrees. The brand that can use polypropylene fabric must be fancy for its environmental protection, because the energy consumption used is much lower than that of other several kinds of nylon.

Polypropylene colored yarn characteristics: environmental protection, antibacterial deodorant, wet perspiration, good warmth and other characteristics by sports clothing, underwear, swimwear brand enterprises of all ages, ultra-fine denier polypropylene fiber DTY polypropylene fine denier is a kind of added Elastic, with environmental protection, light weight, one-way permeable, moisture wicking, chemical resistance, low thermal conductivity, antibacterial deodorant, bright color without dyeing and other advantages.

Through the above description, I believe that you have further understanding of polypropylene colored yarn.
