Problems solved by technology

At present, swimwear fabrics are generally interwoven with spandex and nylon or polyester, but this swimwear fabric has poor chlorine and UV resistance
Because swimwear is often soaked in chlorine water for a long time or exposed to sunlight for a long time during wearing, the chlorine water or ultraviolet rays will oxidize and accelerate the degradation and aging of spandex and nylon or polyester, resulting in fabrics loss of elasticity and color vibrancy

Embodiment 1

[0027] DOW XLA polyolefin elastic fiber comes from The Dow Chemical Company (The Dow Chemical Company), with a thickness of 40D; PTT polyester fiber comes from DuPont in the United States, with a thickness of 40D, consisting of 12 monofilaments; both raw materials can be passed available in the market. The model of the weaving machine is HKS2-3E32.

[0028] First warp the polyolefin elastic fibers and polyester fibers respectively, and then weave them on a warp knitting machine to obtain gray fabrics of elastic fabrics; among them, the let-off of DOW XLA polyolefin elastic fibers is 850mm / R; the PTT polyester fibers The let-off amount is 1440mm / R; the weaving density is 22.7 courses / cm; the structural organization of the fabric is velveteen weave. Then pre-dye and finish the elastic fabric gray cloth to remove oil and heat shrink. First, raise the temperature from room temperature to 60°C and keep it warm for 20 minutes. The heating rate is 2°C per minute; then raise the temp...

Abstract

The invention discloses a face fabric of intercrossed polyolefin flexible fiber and polyester fiber, and relative processing technique. The face fabric is formed by DOW XLA polyolefin flexible fiber in 15-35% weight and the PTT polyester fiber in 65-85% weight; the woven structure can be warp velveteen, double velveteen or double fabric. The processing technique comprises: knitting, pre-treating before colorizing, pre-shaping before colorizing, colorizing and shaping. The surface fabric has better flexibility and anti-chemical property, which has small flexible change even it is dipped in water / seawater for long time. It has better extension recover property, which is higher 2-3 times than nylon, with soft feeling, eliminated rough feeling, and high anti-ultraviolet property.

Description

technical field [0001] The invention relates to the technical field of knitted fabrics, in particular to a fabric interwoven with polyolefin elastic fibers and polyester fibers and its processing technology. Background technique [0002] At present, there are many kinds of knitted fabrics on the market, and people have higher and higher requirements for different clothes such as underwear, swimsuits, sportswear and casual clothes. Functional knitted fabrics are especially suitable for these clothes, which is also a kind of fabrics. new development trend. At present, swimwear fabrics are generally interwoven with spandex and nylon or polyester, but the chlorine resistance and UV resistance of this swimwear fabric are poor. Because swimwear is often soaked in chlorine water for a long time or exposed to sunlight for a long time during wearing, the chlorine water or ultraviolet rays in it will oxidize and accelerate the degradation and aging of spandex ...
