Problems solved by technology

Disclosed as CN1776055A is a kind of silk polyester horizontal strip knitted fabric, adopts silk filament and dyed polyester filament to feed knitting machine respectively and produces, but this method still fails to improve the weavability of silk, and only stripes can appear on the cloth surface Shaped pattern, little change in pattern
In addition, CN 1397670A discloses a multi-strand high-twisted knitting yarn and its production process, which uses silk and other fibers for parallel twisting. In the process, the silk and other fibers must be twisted separately before parallel twisting , complex and time-consuming engineering

Embodiment 1

[0034] The double-twisted yarn obtained above is woven on a 28G single-jersey knitting machine to obtain a weft plain knitted gray cloth. The obtained gray cloth is refined and degummed (95°C degumming, refining weight loss rate is 14%)-after intermediate setting (165°C), and then 0.5 One-bath dyeing of %owf disperse blue-0.5% owf acid blue dye (bath ratio 1:20), the dyeing temperature is 95°C, then the color is fixed and washed, and finally the finishing and setting (setting at 160°C) is carried out to obtain light blue silk-polyester knitting thing.

[0035] The grammage of gained knitted fabric is 130g / m 2 , a thickness of 0.5mm, and a silk content of 45%; according to the drape test, the number of corrugations of the knitted fabric is 10, and the drape coefficient is 15%. The obtained knitted fabric is suitable for use as close-fitting fabrics in spring and summer.

Embodiment 2

[0037] The double-twisted yarn obtained above is woven on a 28G single-jersey knitting machine to obtain a weft plain knitted gray cloth. The obtained gray cloth is refined and degummed (degummed at 95°C, and the weight loss rate of refining is 14%)-after setting in the middle (165°C), and then thickened. Dye the polyester false twisted textured yarn with black disperse dye at 98°C first, then restore and wash; then use acidic black dye to dye silk at 95°C, then fix and wash, and finally finish with water-absorbing resin , 165 ° C stereotypes to obtain thick black silk polyester knitted fabric.

[0038] The grammage of gained knitted fabric is 130g / m 2 , a thickness of 0.5mm, an L value of 15.6, and a silk content of 45%; according to the drape test, the number of corrugations of the knitted fabric is 10, and the drape coefficient is 15%. The obtained knitted fabric is suitable for use as close-fitting fabrics in spring and summer.

Embodiment 3

[0040] Feed the combined twisted yarn and 30D spandex obtained above into a 28G single-jersey knitting machine, and weave to obtain an elastic weft plain knitted gray fabric. After setting (165°C), the polyester false-twist textured yarn is dyed purple with disperse dyes at 95°C, and then the silk is dyed silver-gray with acid dyes at 95°C. After the setting is obtained, a "purple flash silver" elastic knitted fabric is obtained.

[0041] The grammage of the obtained knitted fabric is 150g / ㎡, the thickness is 0.5mm, and the silk content is 42%. According to the drape test, the number of corrugations of the knitted fabric is 12, and the drape coefficient is 10%. The obtained knitted fabric is suitable for use as close-fitting fabrics in spring and summer.

Abstract

The invention discloses polyester knitted fabric and a production method of the polyester knitted fabric. The polyester knitted fabric at least comprises cabled filaments formed by silk filaments and polyester filaments, the polyester filaments are normal-pressure disperse dyeable polyester filaments, and the binary acid component of copolyester forming the polyester filaments comprises over 90% of terephthalic acid structural units by molar weight; the dihydric alcohol component comprises 1-30 % of aliphatic dihydric alcohol structure units by molar weight, wherein the aliphatic dihydric alcohol structure units have side chains, the carbon number of the aliphatic dihydric alcohol structure units is smaller than six, and the copolyester further comprises polyethylene glycol structure units; the knitted fabric comprises 5-95% of the silk filaments by weight. The knitted fabric is dyeable at normal temperature and pressure, it is unnecessary to preprocess silk, knitting and dyeing equipment is wide in application range, the product is diverse in pattern and color, the surface of the knitted fabric can show noble gloss of the silk, and the drapability is excellent; the knitted fabric can further be interweaved with other fibers according to functional requirements to improve product performance.

Description

technical field [0001] The invention relates to a silk-polyester knitted fabric and a production method thereof, in particular to a knitted fabric mainly composed of silk filaments and double-twisted filaments of normal-pressure disperse dyeable polyester filaments and a production method thereof. Background technique [0002] Silk is known to the public as a fiber with noble luster, soft touch, moisture absorption and skin-friendly. However, due to the high hardness of undegummed silk, it is not easy to bend, so it is difficult to apply to knitting. Knitting manufacturers often use softener to treat silk before putting it on the machine, which can reduce the Young's modulus of silk from 1.1Gpa to about 0.6Gpa at most, which can slightly improve the weavability of silk, and at the same time, use fewer channels to feed and reduce downtime Rate. However, according to general experience, yarns with a Young's modulus below 0.5Gpa are more suitable for knitting. At the same tim...
