Embodiment 1

[0031] A production process of high-elastic denim fabric, comprising the following steps:

[0032] ① Spinning double elastic core-spun yarn, with 75D / 48FPTT fiber filament and 40D spandex yarn as core yarn, 42tex100% combed cotton roving as wrapping yarn, and double elastic core-spun yarn is spun by Siro spinning process ; During core wrapping, place two combed cotton rovings on the hanging spindle, and feed them through the rear, middle and front rollers; PTT fiber filaments and spandex yarns are machine-wrapped at a ratio of 1:3, and then placed horizontally on two Between two godet rollers, two combed cotton slivers are fed from the front roller through a godet wheel; the twist is 60 twists / 10cm, the twist is Z twist, and the draft ratio is 3.5 times.

[0033] ②Warping, through the warping machine, the double elastic core-spun yarn is parallel wound on the warp beam, the speed is 350m / min, the tension rod angle is 100°, the parking angle is 160°, the warping head is 440*10,...

Embodiment 2

[0052] The difference between this embodiment and Embodiment 1 is:

[0053] ①In the process of spinning double elastic yarn core-spun yarn, 50D / 24FPTT fiber filament and 30D spandex yarn are used as core yarn, 40tex100% combed cotton roving is used as wrapping yarn, and double elastic yarn core-spun yarn is spun by Siro spinning process Yarn; PTT fiber filament and spandex yarn are machine-packed in a ratio of 1:2.

[0054] ②During the sizing and dyeing process:

[0055] Refining: place the double elastic yarn core-spun yarn in the refining solution containing 3g / L refining agent, 6g / L sodium hydroxide, 2g / L alkali-resistant penetrating agent and 1g / L stabilizer for refining, refining The temperature is 30°C;

[0056] Dyeing: Dye the refined double elastic core-spun yarn in a dyeing solution containing 2g / L sodium hydroxide, 0.6g / L hydrosulfite and 1g / L indigo dye, and the dyeing temperature is 20°C;

[0057] Sizing: the sizing size contains 50 parts by weight of modified s...

Embodiment 3

[0062] The difference between this embodiment and Embodiment 1 is:

[0063] ①In the process of spinning double elastic core-spun yarn, 100D / 72FPTT fiber filament and 50D spandex yarn are used as core yarn, 45tex100% combed cotton roving is used as wrapping yarn, and double elastic core-spun yarn is spun by Siro spinning process Yarn; PTT fiber filament and spandex yarn are machine-packed in a ratio of 1:4.

[0064] ②During the sizing and dyeing process:

[0065] Refining: Place the double elastic core-spun yarn in the refining solution containing 5g / L refining agent, 10g / L sodium hydroxide, 4g / L alkali-resistant penetrating agent and 3g / L stabilizer for refining. The temperature is 50°C;

[0066] Dyeing: Dye the refined double elastic yarn core-spun yarn in a dyeing solution containing 4g / L sodium hydroxide, 0.8g / L hydrosulfite and 3g / L indigo dye, and the dyeing temperature is 40°C;

[0067] Sizing: the sizing size contains 200 parts by weight of modified starch, 20 parts ...

Abstract

The invention provides a high-elastic denim fabric, wherein PTT fiber filaments and spandex filaments are adopted as core yarns. Fasciated yarns are spun into double stretch yarn core-spun yarns, and then the double stretch yarn core-spun yarns are weaved in a three-upward one-downward right twill-weave mode to form cotton roves. After that, the high-elastic denim fabric is prepared successively through the steps of spinning double stretch yarn core-spun yarns, warping, starch dyeing, singeing, desizing, mercerising and washing finished products. The tensile elastic elongation rate of the high-elastic denim fabric prepared by the above method is up to 53.5% and the tensile elastic recovery rate thereof is up to 92.7%. Meanwhile, through setting the ratio of two types of stretch yarns, stretch yarns of different elastic performances can be obtained to meet different elastic requirements. The current situation that the conventional male denim fabric is not elastic can be changed. Meanwhile, the physical and chemical properties and the wearing comfortness of male denim clothes are improved to a certain degree. The fabric is soft and comfortable in hand feeling, good in shape-retaining ability, high in degree of dyeing and good in color fastness, thereby meeting the moderate sport requirement of men when wearing denim clothes. At the same time, the fabric does not unduly fit, thus having a good development prospect and a large value space.

Description

technical field [0001] The invention relates to a fabric, in particular to a high-elastic denim fabric and a production process thereof. Background technique [0002] As a classic casual series fabric, denim has inherited its most original rough, grand and simple style when used in men's clothing fabrics, but the improvement of spinning and weaving methods, as well as the optimized selection and configuration of raw materials, have made men Denim fabrics feel more comfortable and soft, and the colors are not limited to the original coffee and indigo. Various shades of blue, gradient colors, etc. have appeared on denim fabrics. Although men's denim fabrics have greatly improved in terms of feel and style compared with the initial ones, in terms of the fabric itself, men's denim fabrics still maintain the effect of no elastic or slightly elastic. However, today when fashion and sports are both demanded in clothing, non-stretch denim fabrics greatly limit the range of motion f...
