Explore The Appearance Technology That Can Endow Clothes With Natural Wear And Retro

The technology of clothes stir frying snowflakes is a special clothing washing process, which makes the fabric present a natural mottled sense of hierarchy and a sense of old age through specific steps. This process is used in jeans, T-shirts, sweaters and other clothing.

The following are the principles and methods of the snowflake frying process:

Principle:

The principle of the snowflake frying process is to polish the clothes by using pumice containing potassium permanganate. Potassium permanganate reacts with the dyes on the clothes, causing oxidation and fading of the dyes, forming irregular white spots. These white spots are similar to snowflakes, so they are called "fried snowflakes". This process can give clothes a natural wear and retro appearance.

method:

Pretreatment: desizing the jeans to remove the size and impurities on the fabric.

Snowflake washing process: soak the dry pumice with potassium permanganate solution, dry grind it with clothes in a special rotary cylinder, and polish it on clothes through pumice to make potassium permanganate react with dyes to form an irregular fading effect.

Post treatment: put the clothes washed by snowflakes into a water washer, and use oxalic acid, hydrogen peroxide, etc. for water treatment to remove manganese compounds on pumice, and then wash and rinse them.

Reduction neutralization: reduce potassium permanganate to manganese dioxide with reducing agent, and then neutralize the residual acid with neutralizer to protect the color of clothes.

Soft after washing: wash the clothes with clean water, and add softener to make the clothes softer.

Drying or drying: drying or drying clothes to complete the whole process.

The process of frying snowflakes can make clothes show a unique style, but there are also some problems, such as the large loss of pumice, which requires secondary sewage treatment, which not only increases costs, but also does not conform to the principles of environmental protection and sustainable development. In addition, due to the influence of sunlight and moisture, the finishing agent and dye may react, causing the snowflake pattern on the gray cloth to appear green.

Can the snowflake washing process be carried out at home DIY?

The snowflake washing process is a professional garment washing process, which involves the use of potassium permanganate solution and pumice to polish clothes, as well as the subsequent oxalic acid neutralization, washing, softening agent and other steps. This process requires specific equipment and conditions, such as special rotary cylinders and industrial laundry, as well as precise control of temperature and pH value. Therefore, the snowflake washing process is not suitable for ordinary washing machines at home.

Spray the clothes with potassium permanganate and put them directly into the washing machine for washing, which can not obtain professional snowflake frying effect. The effect of frying snowflakes requires specific technological processes and conditions, including the use of dry pumice mixed with potassium permanganate solution for dry grinding with clothes, and the subsequent steps of washing, neutralization, softening agent, etc. These steps need to precisely control the chemical reaction and physical action to ensure the uniformity of the snowflake effect and the safety of clothing.

Only adding potassium permanganate solution into the washing machine is difficult to achieve the ideal snowflake effect due to the lack of professional dry grinding and subsequent processing steps. In addition, potassium permanganate is a strong oxidant. Direct use in household washing machines may cause damage to washing machines and clothes, and there are safety risks. Therefore, it is not recommended to try this method in the home washing machine to obtain the effect of frying snowflakes.

The main reasons include:

Professional equipment demand: The snowflake frying process requires the use of special rotary cylinders and industrial washing machines, which are usually only used in professional laundry factories, and household washing machines cannot provide the same effect and conditions.

Chemical treatment: this process involves the use of potassium permanganate, oxalic acid and other chemicals, which may pose risks to the family environment and personal health, and need professional knowledge and safety measures to deal with them.

Environmental impact: The process of frying snowflakes will produce waste such as pumice slag, which requires secondary sewage treatment, which is difficult to achieve in the home environment and does not conform to the environmental protection principles.

Operation complexity: The process steps are complex, requiring precise control of speed, temperature and pH value, which are difficult to precisely control in the home environment.

To sum up, the snowflake washing process is not suitable for home washing machines, but should be operated by professionals in professional laundry factories. If you want to do DIY at home, you must develop processes and products that meet the above requirements.

What is snow powder?

Snow powder in the process of frying snowflakes is a special chemical agent, which is mainly used for washing jeans to produce a snowflake like fading effect. According to the patent information in the search results, the raw materials of snow chemical powder include the following components: 5-20 parts of potassium permanganate, 10 parts of phosphoric acid, 5-20 parts of deionized water and 20-40 parts of BHT (dibutyl hydroxytoluene). The preparation method of the snow melting powder includes mixing potassium permanganate, phosphoric acid and deionized water to form manganese liquid, then putting BHT into the mixing tank, adding manganese liquid into the mixing tank for reaction, and finally obtaining snow melting powder for cowboy frying snowflakes.

The use of snow chemical powder can reduce equipment wear, avoid fine sand residue, reduce the pressure of subsequent sewage treatment, and the amount is very small, which can greatly reduce production costs. In practical application, snow powder is added to the equipment for frying snowflakes, and fried together with clothes to achieve the effect of snowflakes. Compared with the traditional process of using pumice to stir fry snowflakes, this process is more environmentally friendly and cost-effective.

Does the process of frying snowflakes have special requirements for clothing pigments?

The process of frying snowflakes really has special requirements for clothing pigments. According to the search results, the most suitable pigments for the snowflake frying process are indigo and high-quality sulfur dyes. These pigments can form snowflake like white spots on clothes after being processed by the process of frying snowflakes, producing a natural abrasion and retro appearance. The fabric washed with snowflakes can achieve the effect similar to that of stone mill washing. The cloth surface will show irregular cloud patterns with blue background and white spots, which has a natural beauty effect like "blue sky and white clouds". Therefore, it is very important to select appropriate pigments when frying snowflakes to ensure the beauty and nature of the final effect.

Is it feasible to use printing method to print fried snowflakes?

It is feasible to use printing method to print the effect of fried snowflakes, and this technology has been applied in the market. According to the search results, there is a printing process called "freezing snowflake", which can form a fine sand feeling and delicate hand feeling effect on the surface of printed products after the substrate such as gold card paper, silver card paper, laser card paper, PVC, etc. is wrinkled by ultraviolet light and cured by UV light. This process has the characteristics of fine patterns, strong three-dimensional sense, luxury and elegance in vision, and is widely used in cigarette and wine boxes, calendars, gift box packaging or other exquisite prints.

In addition, there is also a multi-color and multi-point printing method, which uses microcapsule dyes. In the printing color paste, microcapsule dyes of different colors will not be mixed into one color due to the coating of the capsule film. Only after printing, the capsule film is broken through fixation conditions such as steam, the dyes of various colors will be released to color the fibers separately, A variety of colors and unique patterns are formed. This method can give people a feeling of "seeing color from afar and flowers from afar", which is different from the general snowflake effect and has a unique style.

Therefore, through specific printing technologies, you can indeed print the effect similar to fried snowflakes on clothes. These technologies can create unique visual effects, and each finished product is unique.
