Fabric with frosty water effect, garment and processing method thereof

Abstract

This invention provides a fabric, garment, and processing method with a frosted wash effect, relating to the field of textile finishing technology. The method includes design sketches, preparation of color pastes, fabric treatment, curing treatment, and garment washing steps. By designing different sketches, using different combinations of adhesives with varying wash resistance, different curing conditions, or different curing agent application methods, a uniform frosted white, locally mottled, or gradient frosted wash effect can be achieved. This invention features a simple process, low cost, and avoids the use of strong oxidants, strong acids, and strong reducing agents, making it more environmentally friendly. Quality is more controllable, the style is more consistent (small batch variation), and the effect is stable after washing. It is suitable for various textile fabrics. Obtaining a frosted white effect typically involves a snowflake-making process using a mixture of potassium permanganate (a strong oxidant) and phosphoric acid (a moderately strong acid). Oxidation and fading are achieved by stirring the fabric with a medium, but this method suffers from serious environmental pollution, complex processes, and unstable quality.

Description

Technical Field

[0001] This invention relates to the field of textile finishing technology, specifically to a fabric, garment, and processing method with a frosting wash effect. Background Technology

[0002] In the field of textile finishing, achieving a frosty white effect is a common requirement, traditionally achieved using a snowflake-making process. The main steps of the snowflake-making process involve spraying a mixture of potassium permanganate (a strong oxidizing agent) and phosphoric acid (a moderately strong acid) onto a medium (the medium can be of various shapes, such as round, square, triangular, irregular, powdery, or foamy; and of different materials, such as sand, foam, zeolite, silica gel balls, or cotton balls). The medium is then used to stir-fry the fabric or garment. The unevenly distributed oxidizing agent on the medium oxidizes the points of contact with the fabric, destroying the dye and ultimately revealing a frosty white effect.

[0003] However, the traditional method of making fried snowflake ...

[0004] Severe environmental pollution:

[0005] The use of strong oxidizing agents such as potassium permanganate and moderately strong acids such as phosphoric acid is harmful to the environment and human health.

[0006] Strong reducing agents are needed to remove excess strong acids and strong oxidizing agents, resulting in a large amount of wastewater.

[0007] The abrasion of media (such as pumice, sand, etc.) produces waste residue, increasing the difficulty of wastewater treatment.

[0008] Complex process, inconsistent quality:

[0009] Uneven distribution of oxidant on the medium leads to uncontrollable frosting effect and significant style differences.

[0010] Uneven wear of the medium during the stir-frying process results in large cylinder differences and poor consistency in batch production.

[0011] The degree of oxidation is difficult to control precisely, and problems such as over-oxidation or under-oxidation are prone to occur.

[0012] Damaged fabric:

[0013] Friction between the medium and the fabric can damage the fabric fibers, reducing the fabric's strength and lifespan.

[0014] Media residue can easily embed itself in the fabric structure, increasing the difficulty of cleaning and affecting the fabric's feel and appearance.

[0015] High cost:

[0016] The process is complex, the production cycle is long, and the labor costs are high.

[0017] It requires the use of large quantities of chemical reagents and media materials, resulting in high material costs.

[0018] Wastewater treatment and waste disposal are costly.

[0019] Therefore, there is a need for a fabric finishing method that is simple, low-cost, environmentally friendly, and produces stable results after washing, to replace the traditional snowflake process and achieve the contrast and light and dark effects of the frosted wash style. Summary of the Invention

[0020] The purpose of this invention is to overcome the shortcomings of the prior art and provide a fabric, garment and processing method that achieves a frosted wash effect after washing by controlling the difference in the washability of the adhesive, which can replace the traditional snowflake process.

[0021] A fabric processing method with a frosting wash effect, characterized by comprising the following steps:

[0022] Design sketches: Design sketches in the style of frosty wash, which is a frosty white style effect with contrasting shades and brightness on the fabric. The visual effect can be roughly uniform, locally mottled, or gradient.

[0023] Preparation of color paste: A color paste is prepared according to the artwork. The color paste contains a binder, a coating, and water, wherein:

[0024] Adhesive: The dosage is 10-300g / L, and at least one of the following methods can be selected:

[0025] Adhesive combinations with different wash resistance levels: high wash-resistant adhesives account for 10-90% of the total adhesives, and low wash-resistant adhesives account for 10-90% of the total adhesives.

[0026] The washability of the same adhesive can be controlled by different curing conditions.

[0027] The same adhesive has parts with added hardener and parts without added hardener.

[0028] The same adhesive is partially cured with a conventional curing agent and partially cured with a latent curing agent.

[0029] Coating: dosage 5-100g / L; Water: balance.

[0030] Fabric treatment: The colored paste is applied to the fabric in the following manner:

[0031] Application methods: single-sided application, double-sided application, or local application

[0032] Application processes: Rotary screen printing (speed 10-100m / min), flat screen printing (speed 5-40m / min), digital printing (speed 3-50m / min), padding (puffing rate 50-100%), or soaking (time 5-30min).

[0033] Curing treatment: For fabrics with applied colored paste, a curing treatment can be performed, and at least one of the following methods can be selected:

[0034] Hot air drying: temperature 100-230℃, time 15-300s, vehicle speed 20-100m / min

[0035] Temperature gradient curing: High wash resistance zone temperature 120-180℃, time 20-300s; Low wash resistance zone temperature 60-120℃, time 20-300s.

[0036] Radiation intensity control: UV intensity 100-300 W / cm² for high wash resistance areas, time 0.5-10 seconds; UV intensity 20-80 W / cm² for low wash resistance areas, time 0.1-10 seconds.

[0037] Catalyst zoning method: Apply 0.5-10 g / L of catalyst to high washability zones; apply 0.1-10 g / L of inhibitor to low washability zones.

[0038] Garment washing: After the cured fabric is cut and sewn into garments, it is then washed. The washing conditions are as follows:

[0039] Temperature 20-70℃, time 5-90 minutes, bath ratio 1:5 to 1:20; furthermore, add 0.1-10g / L of cellulose fiber enzyme and at least one of soda ash and caustic soda to the washing solution, in a dosage of 5-80g / L.

[0040] During the washing process, the pigments fixed by the wash-resistant adhesive remain, creating a darker effect, while the less wash-resistant adhesive washes away along with the pigments, resulting in a lighter effect. The final product is a garment with a frosted wash effect.

[0041] Furthermore, the high wash-resistant adhesive is selected from one or more of cross-linked acrylate, polyurethane, and epoxy resin adhesives; the low wash-resistant adhesive is selected from one or more of non-cross-linked acrylate and polyvinyl acetate adhesives.

[0042] Furthermore, the additional curing agent is selected from one or more of polyisocyanates, aziridines, and epoxy curing agents; the amount of the additional curing agent is 1%-20% of the total amount of adhesive.

[0043] Furthermore, the conventional curing agent is selected from one or more of polyisocyanate, polyamide, acid anhydride, and amine curing agents; the latent curing agent is selected from one or more of heat-latent, light-latent, moisture-latent, and microencapsulated curing agents.

[0044] Furthermore, the amount of the conventional curing agent is 1%-20% of the total amount of the adhesive, and the amount of the latent curing agent is 1%-10% of the total amount of the adhesive.

[0045] Furthermore, the fabric is selected from one or more fibers made of cotton, linen, polyester, nylon, wool, silk, viscose, lyocell, cupro, and bamboo viscose.

[0046] The present invention also provides a fabric obtained by the above-mentioned fabric processing method, characterized in that: the fabric has a contrast of light and dark shades and a light and dark effect in the style of frosted wash, and its wash fastness varies from level 1 to 4 depending on the region.

[0047] The present invention also provides a garment, characterized in that: the garment is made of the above-mentioned fabric and has a contrasting light and dark effect with a frosted wash style.

[0048] Beneficial effects:

[0049] This invention features a simple and low-cost process that does not use strong oxidants, strong acids, or strong reducing agents, making it more environmentally friendly. It also offers better quality control, more consistent style (small batch variation), and stable results after washing, making it suitable for various textile fabrics. Attached Figure Description
