Problems solved by technology

[0008] This means that it is impossible for regenerated cellulose enterprises to accept orders of less than 10 tons. Even if they accept orders, their production costs will be much higher than conventional varieties, and the amount of waste will be huge
This is why domestic large-scale cellulose fiber manufacturers have developed colored fibers but are unable to enter the market.

Embodiment 1

[0060] According to the ratio of red: yellow: natural color cotton: black = 1:1:7.8:0.2, the fiber distribution and color matching are carried out, and the cotton distribution and its weighing equipment are used to quantitatively feed the A104 type flat carding machine; the carding machine is carded and clustered Finally, it becomes a sliver with a certain mixing degree, and the fixed weight is 20g / 5m. The draw frame chooses the second draw frame, and the fixed weight of the cooked sliver is 20g / 5m. The cooked sliver is drafted 8 times on the roving frame to obtain a roving, and the fixed weight is 5g / 10m. The roving is drafted 27 times on the spinning frame to obtain a spun yarn with a fineness of 18.5tex (32 English counts).

Embodiment 2

[0062] According to the ratio of red: blue: natural color cotton: black = 1:1:7:1, the fiber distribution and color matching are carried out, and the cotton distribution and its weighing equipment are used to quantitatively feed the A104 type flat carding machine; the carding machine is carded, After bundling, it becomes a sliver with a certain mixing degree, and the fixed weight is 20g / 5m. The draw frame chooses the second draw frame, and the fixed weight of the cooked sliver is 20g / 5m. The cooked slivers are spun yarns with a fineness of 50tex (13 English counts) on the rotor spinning machine.

Embodiment 3

[0064] According to the ratio of yellow: blue: natural color cotton: black = 3:2:4:1, the fiber distribution and color matching are carried out, and the cotton distribution and its weighing equipment are used to quantitatively feed the A104 type flat carding machine; the carding machine is carded, After bundling, it becomes a sliver with a certain mixing degree, and the fixed weight is 20g / 5m. The draw frame chooses the second draw frame, and the fixed weight of the cooked sliver is 20g / 5m. The cooked slivers are spun yarns with a fineness of 50tex (13 English counts) on the rotor spinning machine.

Abstract

The invention discloses a production method of regenerated cellulose fiber and cotton blended colored yarns. The regenerated cellulose fiber and cotton blended colored yarns are obtained by blending more than one of white, red, yellow, blue, purple, orange, green and black regenerated cellulose fibers and cotton. In the method, the colored cellulose fibers are directly used, the consumption of water and energy and the sewage emission are not increased, and problems caused by cotton fiber dying are completely solved; and compared with dyed yarns, the blended colored yarns has the advantages that: the water usage and the sewage emission can be reduced by 50 tons, the steam consumption can be lowered by 5 tons, and 1,000 kilowatt hours of electricity can be saved in the production of every ton of the blended colored yarns. The colored cellulose fibers in seven basic colors can be steadily produced by fiber production enterprises, so that the problems of unstable factors and waste brought to the generated cellulose fiber production enterprises due to frequent color change are solved, and the production cost is lowered. The colored yarns obtained by blending the regenerated cellulose fibers in the seven basic colors are fashionable, environmentally-friendly and healthy. The blended yarns can be produced on the conventional cotton spinning equipment and new equipment is not required to be purchased or the conventional equipment is not required to be modified.

Description

technical field [0001] The invention relates to a yarn production technology, in particular to a production method of regenerated cellulose fiber and cotton blended colored spinning yarn. Background technique [0002] The dyeing and finishing process is a process with high energy consumption and high sewage discharge in the textile industry, which has always been criticized by the society. Traditionally, for natural fibers, the color must be obtained through printing and dyeing. [0003] Colored spinning reverses the traditional textile process, and mentions the coloring link before spinning. After the process is changed, it can be made into a blend of cotton, hemp, wool, silk, chemical fiber and other raw materials. Its advantages: First, it completely solves the problem of cylinder difference in gray cloth dyeing. As long as the color is determined in color spinning, it can achieve unlimited batches; second, color spinning solves the dyeing problem of various fabrics with...
