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.

Example Embodiment

[0043] Example 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% spun silk staple fibers and 60% cotton; 10wt% of the raw cotton fibers are blue;

[0046] Said preparation is obtained by a method comprising the following steps:

[0047] 1) The elastic short fibers of the elastic silk and the cotton fibers are mixed to form a mixed raw material;

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

[0049] 3) The cotton lap is combed into sliver on the carding machine; the raw sliver weight is 22 g / 5 m; the doffer speed is 20 rpm; ;

[0050] 4) The raw sliver is combined and drawn for three times on the drawing frame to form a sliver; the final sliver is quantitatively 20.5g / 5m; the number of slivers is 8;

[0051] 5) Draft the sliver into roving B on the roving frame;...

Example Embodiment

[0065] Example 2

[0066] This embodiment is a blended core-spun yarn for fine-count wool-containing knitted sweaters.

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

[0068] 1) The raw material fibers of the roving B are: 60wt% wool, 40wt% cotton; cotton fibers have 10wt% black;

[0069] 2) The wool fiber can also be pre-treated to prevent its electrostatic effect;

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

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

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

[0073] 6) The raw sliver is combined and drafted for three times on the drawing frame to form a sliver; the sliver is quantitatively 20.5g / 5m at the end; the number...

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...
