A novel two-color high-elastic fancy yarn and its production method

technical field

The invention relates to the field of novel textiles, in particular to a novel two-color high-elastic fancy yarn and a production method thereof.

Background technique

In recent years, the fancy yarn industry has achieved a series of new technological achievements, and has been continuously improved and enhanced in the development, making the products develop in the direction of diversified raw materials, compound structures, and diversified varieties. These achievements benefit from The adoption of new raw materials, new processes, new equipment and new control methods has brought vitality to the development of fancy yarn varieties, and the rational use of raw materials has brought essential changes to fancy yarn products. Moreover, the development of fancy yarn products makes the yarn have color and structure, that is, full of layer changes, and full of three-dimensional effect. It is widely used in clothing fabrics and decorative fabrics, and is deeply loved by consumers. The added value and economic benefits are very considerable, injecting new vitality into the textile industry.

Color-spun fancy yarns and their fabrics are more popular, and the production of fancy yarns on cotton spinning equipment is one of the hot spots in the development of new textile products today. Color spinning fancy yarn adopts the new technology of "dyeing first, then spinning", which subverts the traditional spinning process, makes the production process more environmentally friendly and energy-saving, and can obtain unique color mixing effects and product styles. The fabric composed of colored spinning fancy yarn has a three-dimensional mixed color style, with natural and subtle colors, and a strong hazy feeling, which can meet the individual needs of modern consumers and has high added value.

The core-spun yarn is generally made of synthetic fiber filaments with good strength and elasticity as the core yarn, and the outsourcing cotton, wool, viscose fiber and other short fibers are twisted and spun together. Excellent properties of fiber. Among them, the elastic core-spun yarn with spandex and nylon as the core yarn has high strength and elasticity, and the outer fiber uses cotton, wool, hemp and silk to make the fabric have good air permeability and Dyeing effect, the style of natural fiber fabrics, comfortable to wear. It is widely used in weaving one-way and two-way elastic fabrics, such as high-grade denim and elastic sports fabrics. The products are deeply loved by consumers.

In view of this, on the basis of the principle of sirofil-spun, embedded spinning and core-spun yarn, the present invention explores a new spinning method, creates a new technology of sirofil-spun, and develops a new type of two-color yarn based on this technology. High stretch fancy yarn. The new sirofil-spun is a multifunctional spinning technology, which is improved on the basis of sirofil-spun. The QFA1528 spinning frame is refitted, and the core yarn device, filament tension disc, and double groove guide wire are installed. wheel for spinning. Its unique spinning system design has unique advantages in spinning some fiber materials with poor spinnability and yarns of various designs and colors. It uses a colored filament or colored spun yarn to go through the double-groove godet wheel through the filament tension coil. On the left slot, an elastic spandex filament drawn by the core-spun yarn device bypasses the right slot of the double-slot guide wheel, and then feeds to the front roller at the same time; the cotton roving is fed from the rear roller, and the double-slot guide wheel is adjusted so that The position of the right groove of the double groove guide wheel is on the same center line as the roving fed by the rear roller, so that the roving fed by the rear roller first forms a core-spun twisting mechanism with the spandex filament in the right groove, and then with the left The colored filament or colored spun yarn forms a sirofil-spun mechanism, which is wrapped and twisted into a yarn, and a spun yarn with both design and color and elasticity is spun, and finally a new two-color high-elastic fancy yarn with high added value is obtained.
