Embodiment 1

[0033] The present embodiment provides a bath agent, which includes the following components by weight: 5 to 15 parts of sodium acetate, 5 to 15 parts of sodium metasilicate, 5 to 20 parts of sodium bicarbonate and 5-20 parts of sodium carbonate; the pH value of the solution formed by dissolving 1-6 g of the same bath agent in 100 ml of water is between 10.5 and 13.5.

[0034] For example, among them, 3 to 5 parts of sodium acetate, 3 to 5 parts of sodium metasilicate, 10 to 13 parts of sodium bicarbonate, and 10 to 13 parts of sodium carbonate are preferable.

[0035] For example, the sodium acetate, sodium metasilicate, sodium bicarbonate and sodium carbonate can be directly ground and mixed after weighing to prepare the same bath agent, so the preparation method of the same bath agent is particularly simple.

[0036] For example, the same bath agent can also be a solution prepared according to the above-mentioned mass ratio by sodium acetate solution, sodium metasilicate so...

Embodiment 2

[0038] This embodiment provides a method for applying the same-bath agent described in Example 1 to dyeing, the method is to apply the same-bath agent to one-bath and one-step process dyeing, and it is polyester nylon fabric, polyester cotton fabric, Nylon-cotton fabric or polyester-nylon-cotton fabric dyeing.

[0039] For example, see figure 1 As shown, the same bath agent can be applied to the one-bath and one-step dyeing process for dyeing polyester-nylon-cotton core-spun yarn, and the dyeing is black, specifically including: controlling the bath ratio to 1:8-10, Add 50g / L of sodium sulfate, 3.5g / L of the same bath agent and 1.5g / L of printing and dyeing auxiliaries IWS, run for 5 to 10 minutes, add z% disperse dyes, and run for 5 to 10 minutes Finally, add x% acid dyes, add y% reactive dyes after running for 5-10 minutes, and start to heat up after running for 5-10 minutes, and the temperature rise rate is controlled at 2-3°C / min. When the temperature rises to 100°C, sto...

Abstract

The invention relates to the technical field of dyeing and finishing, and provides a same bathing agent and a method applied in dyeing thereof, aiming at solving a two-bath two-step dyeing method of current brocade / cotton or polyester / brocade / cotton fiber, and changing to one-bath one-step method. The same bathing agent is prepared from the following components in parts by weight: 5 to 15 parts ofsodium acetate, 5 to 15 parts of sodium metasilicate, 5 to 20 parts of sodium hydrogencarbonate and 5 to 20 parts of sodium carbonate. The solution of 1 to 6 g of the same bathing agent dissolved in100 ml of water has a pH of from 10.5 to 13.5. The application method is that the same bathing agent is applied to one-bath one-step process dyeing, and is dyed for polyester brocade fabric, polyestercotton fabric, brocade cotton fabric, or polyester brocade cotton fabric. By using the same bath agent, the two-bath two-step method of the current brocade / cotton or polyester / brocade / cotton fiber can be changed into one-bath one-step dyeing, acetic acid and sodium carbonate in a traditional process can be omitted. Great convenience to printing and dyeing is brought, the printing and dyeing production time is greatly shortened, the consumption of water and electricity is reduced, and the same bathing agent and the method applied in dyeing thereof are very energy-saving and emission-reducing.

Description

technical field [0001] The invention relates to the technical field of dyeing and finishing, in particular, to a bath agent and a method for applying the same bath agent to dyeing. Background technique [0002] Polyester, nylon, and cotton fabrics combine the advantages of the three fibers, and the fabric is crisp, durable, and comfortable, and occupies an important position in contemporary clothing fabrics. It is usually dyed by two-bath two-step over-dyeing method, that is, polyester and brocade are dyed with disperse dyes or disperse / neutral dyes, and cotton is over-dyeed with reactive dyes. This process has the defects of high energy consumption, high pollution discharge, low output and poor benefit. The one-bath and one-step dyeing process is more in line with the dyeing and finishing concept of energy saving, emission reduction, and efficiency enhancement. [0003] The one-bath one-step dyeing process requires the use of a same-bath agent, but the existing same-bath ...
