Problems solved by technology

[0003] In addition, due to the structural characteristics of wool covered by natural scales, after rubbing and kneading under wet conditions, wool fibers are easily displaced and felt shrinkage, so that the finished products made of wool fabrics shrink and deform too much after washing, which affects the service life. Dry cleaning costs are much higher than water washing

Embodiment 1

[0017] The raw material is fine wool with a fiber fineness of 18-20 μm and an average length of about 90 mm.

[0018] Pretreatment process: Inject industrial soft water into the jet dyeing machine at a bath ratio of 1:2, put the wool fabric into the jet dyeing machine, record the water level at this time, add degreasing agent, sodium chloride, and then add sodium bicarbonate to form Pre-treatment solution, the pH value of the pre-treatment solution is 8.3, then heat up to 45°C, keep warm for 30 minutes, drain, wash once with water at 35-45°C, and the ratio of water to bath is 1:12; the amount of degreasing agent is preferably 1.5g, the amount of neutral electrolyte is 4.2% (o.w.f).

[0019] Dyeing process: Inject industrial soft water into the jet dyeing machine based on the height of the previously treated water level, raise the temperature of the industrial soft water to 35°C, add auxiliary agents to the industrial soft water in the following order to form a dyeing solution:...

Embodiment 2

[0026] The raw material is fine wool with a fiber fineness of 18 μm and an average length of about 90 mm.

[0027] Pretreatment process: inject industrial soft water into the jet dyeing machine at a bath ratio of 1:14, put the wool fabric into the jet dyeing machine, record the water level at this time, add degreasing agent, sodium chloride, and then add sodium carbonate to form Treatment liquid, the pH value of the pre-treatment liquid is 8.5, then heat up to 45°C, keep warm for 30 minutes, drain, wash once at 35-45°C, the ratio of water to bath is 1:14; the amount of degreasing agent is preferably 1.8 per liter of water g, the amount of neutral electrolyte 4.5% (o.w.f).

[0028] Dyeing process: Inject industrial soft water into the jet dyeing machine based on the height of the previously treated water level, raise the temperature of the industrial soft water to 40°C, add additives to the industrial soft water in the following order to form a dyeing solution: first add the pe...

Abstract

The invention discloses a production method of a decoloring-preventing wool fabric. The method is characterized by comprising the following steps: washing raw wool, pre-treating for dyeing, dyeing, spinning, weaving and carrying out after-finishing. The step of pre-treating for dyeing is carried out in a pre-treating solution with the pH value of 8.3-8.5, and the pre-treating solution is a water solution composed of an oil removing agent, neutral electrolyte and sodium hydrogen carbonate, wherein the use amount of the oil removing agent is 1.5-1.8 g / L, the use amount of the neutral electrolyte is 4.2%-4.5% (o.w.f), and with proper amount of sodium hydrogen carbonate, the pH value of the pre-treating solution ranges from 8.3 to 8.5. In the step of dyeing, a penetrating agent, a metal chelating agent, an in-bath smoothening agent, a leveling agent, an antistatic agent and a softening agent are added into dyes. The acid neutralization step is carried out in an after-finishing solution with the pH value of 4-6. The cloth cover condition of the wool textile is good and all color fastnesses of the wool textile are good; the wool textile can be directly washed with water by hand and the anti-felting effect of the wool textile is good.

Description

technical field [0001] The invention relates to a processing method of a wool fabric, in particular to a processing method of a wool fabric with good color fastness, which can be directly immersed in water for hand washing or machine washing, and belongs to the technical field of textile dyeing and finishing. Background technique [0002] The traditional wool dyeing process needs to go through a long-term waste dyeing process. The boiling dyeing process is easy to cause damage and yellowing of the wool fabric, which affects the surface style of the fabric. At the same time, the boiling dyeing process does not meet the needs of energy conservation. So far, the wool low-energy dyeing methods that have been proposed mainly focus on low-temperature dyeing, specifically: solvent auxiliaries method, urea method, formic acid method, biological enzyme treatment method, low-temperature dyeing auxiliaries method, ultrasonic dyeing method, low-temperature plasma dyeing method, etc. Bod...
