Problems solved by technology

When the existing yarn-dyed products are produced, the warp and weft yarns are produced and processed separately, and then weaved. This process is divided into two routes for separate production. The process is long and the production cycle is long, which increases dyeing costs, repetitive labor and sewage discharge.

Embodiment 1

[0014] Step 1: Place bobbins and warp beams on the same yarn carrier, add refining agent, caustic soda, and hydrogen peroxide at a rate of 3g of refining agent, 3g of caustic soda, and 5g of hydrogen peroxide per liter of water at room temperature, and mix evenly to make a mixing aid , then put the bobbin and warp beam into the mixing aid with a bath ratio of 1:10, heat up to 100°C at 2°C / min, keep for 60 minutes, and get rid of the mixing aid.

[0015] Step 2: Dyeing at a constant temperature of 60°C, inject clean water at room temperature, add dyes into the clear water, then raise the temperature to 60°C, add sodium starch powder and keep it for 30 minutes, add soda ash for 60 minutes, and drain the waste water.

[0016] Step 3: Wash with water at 60°C, add glacial acetic acid with a mass concentration of 85% at a ratio of 0.5g / l, drain the waste liquid after 15 minutes, then inject water, add soaping agent at a ratio of 2g / l, and soap at 90°C 115 minutes, remove the waste l...

[0019] Step 1: Place bobbins and warp beams on the same yarn carrier, add refining agent, caustic soda, and hydrogen peroxide at a rate of 3g of refining agent, 3g of caustic soda, and 5g of hydrogen peroxide per liter of water at room temperature, and mix evenly to make a mixing aid , then the bobbin and the warp beam are put into the mixing aid with a bath ratio of 1:15, and the temperature is raised to 110° C. at 2° C. / min, and kept for 30 minutes to get rid of the mixing aid.

[0020] Step 2: Dyeing at a constant temperature of 60°C, inject clean water at room temperature, add dyes into the clear water, then raise the temperature to 60°C, add sodium starch powder and keep for 30 minutes, add soda ash for 60 minutes, and drain waste water.

[0021] Step 3: wash with water at 60°C, add glacial acetic acid with a mass concentration of 85% at a ratio of 1g / l, drain the waste liquid after 15 minutes, then inject water, add soaping agent at a ratio of 2g / l, and soap at 95°C for 1...

Abstract

The invention relates to a shape dyeing process for cotton / fibers. The process is characterized in that: cone yarns and yarn beams are placed in the same yarn carrier and dyed by the following steps at the same: 1, bleaching scouring; 2, dyeing; 3, neutralizing and soaping; and 4, color fixing and smoothing treatment. The process has the advantages that: the conventional idea and mode of production is broken through and the one-bath dyeing of two kinds of yarn shapes is realized; and by using the one-bath dyeing of the yarn beams, the process flow of yarn-dyed cloth is simplified, efficiency and carrying rate are improved, a production period is shortened, simultaneously a dye uptake rate is improved, the emission of sewage and environmental pollution are reduced, a utilization rate of equipment is increased, the production dilemma caused by insufficient dyeing equipment is reduced, the cost is reduced, and the requirements on level-dyeing property, repeatability and fastness of the conventional dyeing level are met.

Description

technical field [0001] The invention relates to a cotton / fiber morphological dyeing process, which belongs to the technical field of yarn dyeing in the textile industry. Background technique [0002] Pure cotton fabric is a natural fiber with excellent fiber properties, and is widely loved by consumers, and yarn-dyed products are even more favored by consumers. With the progress of society, more attention is paid to environmental protection. The cost reduction and process shortening of bleaching and dyeing process are particularly important for energy saving and emission reduction. When the existing yarn-dyed products are produced, the warp and weft yarns are produced and processed separately, and then weaved. This process is divided into two routes for separate production. The process is long and the production cycle is long, which increases dyeing costs, repetitive labor and sewage discharge. . Contents of the invention [0003] The object of the present invention is t...
