Embodiment 1

[0034] Cotton yarn is soaked in various vegetable oils, and then rolled on a padding machine so that it contains 80% oil carrying rate.

[0035] Add 5 g of sodium alginate to 95 g of water to prepare a 5% sodium alginate paste. Get 2g (2%) of reactive blue 194 dye, 3g (3%) of ethanol, 3g (3%) of sodium carbonate, 50g (50%) of sodium alginate paste with a mass fraction of 5%, 42g (42%) of water, mix After stirring, it is made into a spray dyeing slurry.

[0036] Tension is applied to the calendered cotton yarn containing vegetable oil, so that the cotton yarn is in a taut state. The prepared spray dyeing paste is added into the spray gun to spray dye the cotton yarn. After spraying, dry it in an oven, and then steam it in steam for 10 minutes. Then rinse most of the vegetable oil and floating color on the cotton yarn with running cold water, then wash in soap solution, wash in cold water, and dry to complete the dyeing.

Embodiment 2

[0041] The cotton yarn is soaked in soybean vegetable oil, and then rolled on a padding car, so that it contains 10%-150% oil carrying rate.

[0042] Add 5 g of sodium alginate to 95 g of water to prepare a 5% sodium alginate paste. Get 2g (2%) of reactive blue 194 dye, 3g (3%) of ethanol, 3g (3%) of sodium carbonate, 50g (50%) of sodium alginate paste with a mass fraction of 5%, 42g (42%) of water, mix After stirring, it is made into a spray dyeing slurry.

[0043] Tension is applied to the calendered cotton yarn containing vegetable oil, so that the cotton yarn is in a taut state. The prepared spray dyeing paste is added into the spray gun to spray dye the cotton yarn. After spraying, dry it in an oven, and then steam it in steam for 10 minutes. Then rinse most of the vegetable oil and floating color on the cotton yarn with running cold water, then wash in soap solution, wash in cold water, and dry to complete the dyeing.

Embodiment 3

[0048]Cotton yarn is dipped in soybean vegetable oil, and then rolled on a padding machine so that it contains 80% oil carrying rate.

[0049] Add 5 g of sodium alginate to 95 g of water to prepare a 5% sodium alginate paste. Change the ratio of reactive blue 194 dye, ethanol, sodium carbonate, sodium alginate paste with a mass fraction of 5% and water (in Table 3) in the color paste, stir after mixing, and make a spray dyeing paste.

[0050] Tension is applied to the calendered cotton yarn containing vegetable oil, so that the cotton yarn is in a taut state. The prepared spray dyeing paste is added into the spray gun to spray dye the cotton yarn. After spraying, dry it in an oven, and then steam it in steam for 10 minutes. Then rinse most of the vegetable oil and floating color on the cotton yarn with running cold water, then wash in soap solution, wash in cold water, and dry to complete the dyeing.

Abstract

The embodiment of the invention discloses a ring dyeing method for cotton fibers. The method comprises the following steps of dipping the cotton fibers in vegetable oil, and carrying out rolling to obtain a rolled cotton fabric; applying tension to the rolled cotton fibers so as to tighten the rolled cotton fibers; carrying out spray dyeing on the tightened cotton fibers by adopting color paste containing reactive dye to obtain a spray-dyed cotton fabric; and drying the spray-dyed cotton fibers, then fixing the color, carrying out cold water washing after the color fixation is completed, and after cold water washing is completed, sequentially carrying out soaping, cold water washing and drying to obtain ring-dyed cotton fibers. According to the embodiment of the invention, the cotton fibers are dyed in a spray dyeing manner, so that the dyed cotton fibers have the ring dyeing effect, the dyeing cost of the cotton fibers is reduced, and meanwhile, the environmental pollution is reduced.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a cotton fiber ring dyeing method. Background technique [0002] Denim clothing has always occupied a special position in the fashion field, and is deeply loved by consumers of all ages for its breathable, moisture-absorbing, and comfortable style. The coloring of denim can be divided into dyeing and then weaving into cloth and weaving into cloth before dyeing to meet people's daily needs for denim clothing fashion. Most of the pure cotton denim requires colorless bottom and colored outside, so it needs to be dyed first and then woven into cloth, that is, the warp yarn is dyed and the weft yarn is not dyed. Denim requires distressing on the dyed side, which destroys the dye and gives the denim a vintage look. Traditional denim warp dyeing is dyed by indigo dyeing. Before dyeing, the indigo is reduced to a water-soluble leuco, and then the indigo leuco is dyed on the yarn by di...
