Embodiment 1

[0023] A sand washing process for cotton fabrics, comprising the following steps:

[0024] A. After soaking the fresh shells with hydrochloric acid, wash them with clear water, dry them, and crush them until the particle size is 1-3mm;

[0025] B. Calcining the shell powder at a high temperature of 890°C for 2.5 hours;

[0026] C. further pulverizing the calcined shell powder to a particle size of 200-500 μm to obtain micron shell powder;

[0027] D. Add micron-sized shell powder and cotton fabric into the washing machine, and stir together in warm water at 70°C for 35 minutes;

[0028] E. After taking out the cotton fabric, clean it briefly under acidic conditions, rinse it with clean water, and dry it.

[0029] In the step B, after calcining, the porosity of the shell powder is 12-15%.

[0030] In the step D, the dosage ratio of shell powder to cotton fabric is 2.5:10.

[0031] In the step E, the acidic condition is a slightly acidic condition with a pH of 6.0.

Embodiment 2

[0033] A sand washing process for cotton fabrics, comprising the following steps:

[0034] A. After soaking the fresh shells with hydrochloric acid, wash them with clear water, dry them, and crush them until the particle size is 1-3mm;

[0035] B. Calcining the shell powder at a high temperature of 900°C for 4 hours;

[0036] C. further pulverizing the calcined shell powder to a particle size of 200-500 μm to obtain micron shell powder;

[0037] D. Add micron-sized shell powder and cotton fabric into the washing machine, and stir together in warm water at 60°C for 40 minutes;

[0038] E. After taking out the cotton fabric, clean it briefly under acidic conditions, rinse it with clean water, and dry it.

[0039] In the step B, after calcining, the porosity of the shell powder is 10-12%.

[0040] In the step D, the dosage ratio of shell powder and cotton fabric is 3:10.

[0041] In the step E, the acidic condition is a slightly acidic condition with a pH of 5.5.

Embodiment 3

[0043] A sand washing process for cotton fabrics, comprising the following steps:

[0044] A. After soaking the fresh shells with hydrochloric acid, wash them with clear water, dry them, and crush them until the particle size is 1-3mm;

[0045] B. Calcining the shell powder at a high temperature of 880°C for 2 hours;

[0046] C. further pulverizing the calcined shell powder to a particle size of 200-500 μm to obtain micron shell powder;

[0047] D. Add micron-sized shell powder and cotton fabric into the washing machine, and stir together in warm water at 80°C for 30 minutes;

[0048] E. After taking out the cotton fabric, clean it briefly under acidic conditions, rinse it with clean water, and dry it.

[0049] In the step B, after calcining, the porosity of the shell powder is 16-20%.

[0050] In the step D, the dosage ratio of shell powder and cotton fabric is 2:10.

[0051] In the step E, the acidic condition is a slightly acidic condition with a pH of 6.2.

Abstract

The invention discloses a sand washing process for a cotton fabric. According to the invention, calcined shell powder is used as a raw material for sand washing of the cotton fabric, so environmental pollution caused by usage of silica in conventional sand washing is avoided, and the antibacterial properties of the cotton fabric can be improved; good sand washing effect is obtained by controlling the porosity, particle size and usage amount of the shell powder during sand washing; and thus, the sand washing process provided by the invention is a novel environment-friendly fabric treating process.

Description

technical field [0001] The invention relates to a fabric processing method, which belongs to the field of textiles, and in particular to a sand washing process for cotton fabrics. Background technique [0002] With the improvement of material living standards, consumers' requirements for the quality and wearing performance of clothing products are no longer limited to keeping warm. Consumers not only need comfort, but also pursue diversified, personalized and distinctive products. For example, retro nostalgic style jeans are specially made to be faded or even worn out at the hips and knees. This method is usually treated with special equipment such as fading agents and sand washing. And for the clothes that cotton fabric is done, because strength is much lower than the fabric of jeans, therefore can't adopt the method that is usually similar to making jeans to carry out old-fashioned treatment to the clothes that woolen fabrics do.
