Problems solved by technology

For example, wool-containing fabrics are soft to the touch and have good thermal insulation effect, but poor releaseability, low production efficiency, high cost of thin and high counts, and are not easy to wear next to the body; hemp fiber is breathable and cool, but the fiber is short and the textile efficiency is low, and there is obvious itching feeling when worn next to the body. High-elastic spandex filament fabric has good elasticity, but also has a strong sense of restraint. At the same time, the fabric is prone to air bubbles after a long period of stress, and it is rarely used on high-fine-count yarn fabrics; although these fiber materials have obvious advantages, they are also very Popular, but in today's pursuit of fashion and emphasis on functional characteristics, its shortcomings also restrict its further application

Embodiment 1

[0044] The preparation method of roving B in the present embodiment is as follows:

[0045] The raw material fibers of the roving B are 40% stretch-elastic short fibers and 60% cotton; 10wt% of the raw cotton fibers are indigo;

[0046] Described adopting the method preparation comprising the following steps to obtain:

[0047] 1) Shu elastic silk elastic short fiber and cotton fiber are mixed to form mixed raw materials;

[0048] 2) The mixed raw materials are made into laps in the cleaning process, and the lap weight is 420 g / m; the lap length is 36 meters;

[0049] 3) Comb the lap into slivers on the carding machine; raw sliver weight is 22 g / 5 m; doffer speed is 20 rpm; distance between cover plate and cylinder card clothing is 8, 7, 6, 6, 7 ;

[0050] 4) The raw sliver is combined and drafted three times on the draw frame to form a sliver; the sliver final weight is 20.5g / 5m; the combined number is 8; the final draft is 8.59 times, and the speed is 320m / min;

[0051] ...

Embodiment 2

[0066] In this example, the melange spun core-spun yarn is used for fine-count wool-containing knitted sweaters.

[0067] Roving B is prepared by the method comprising the following steps:

[0068] 1) The raw material fiber of roving B is: 60wt% wool, 40wt% cotton; Cotton fiber has 10wt% black;

[0069] 2) It is also possible to pre-treat the wool fiber to prevent its electrostatic effect;

[0070] 3) mixing wool fiber and cotton fiber to form mixed fiber;

[0071] 4) The mixed fibers are made into laps in the cleaning process, and the lap weight is 420 g / m; the lap length is 36 meters;

[0072] 5) Comb the laps into raw slivers on the carding machine; raw sliver weight is 18-24g / 5m; doffer speed is 15-22 rpm; distance between cover plate and cylinder clothing is 8,7,6 ,6,7;

[0073] 6) The raw sliver is combined and drafted three times on the drawing frame to form a sliver; the final weight of the sliver is 20.5g / 5m; the combined number is 8; the draft is 8.5 times, and t...

Abstract

The invention relates to mixed-color core-spun yarn and a production device and a production method thereof. The production method includes following steps: subjecting sliver A prepared through a drawing process and thick yarn B prepared through a roving process to roving to obtain thick yarn C, wherein the thick yarn C is core-spun yarn, the sliver A is skin yarn, and the thick yarn B is core yarn; subjecting the thick yarn C and filament D to a spinning core-spun yarn process to produce the mixed-color core-spun yarn. The mixed-color core-spun yarn produced by the method is of a three-layeroverlapped structure, has the advantages of high shape maintaining performance, elasticity and obvious functional feature, can form special color effect according to color selecting, matching and adjusting, can be widely used for knitting, weaving and knitwear and is prime yarn for making fashionable fabric for high-grade underwear, sports T shirts and casual wear.

Description

technical field [0001] The invention relates to the field of textile yarns, in particular to a mixed-color spinning core-spun yarn, a production device and a production method thereof. Background technique [0002] As people's requirements for personalized clothing are increasing day by day, various fabric properties or effects may become the reason for people to choose clothing. How to maximize strengths and avoid weaknesses is the key to satisfying consumer needs. For example, wool-containing fabrics are soft to the touch and have good thermal insulation effect, but poor releaseability, low production efficiency, high cost of thin and high counts, and are not easy to wear next to the body; hemp fiber is breathable and cool, but the fiber is short and the textile efficiency is low, and there is obvious itching feeling when worn next to the body. High-elastic spandex filament fabric has good elasticity, but also has a strong sense of restraint. At the same time, the fabric i...
