1, washing method. Because the surface of rabbit hair fiber is composed of many scales, once cashmere products are stirred and washed by washing machine, it will make cashmere products felted, destroy the excellent properties of cashmere and affect its beauty. Therefore, cashmere must not be washed with a washing machine. It is better to dry-clean it or take it off and wash it by hand. The method is as follows: When it is slightly soiled, first pour neutral detergent (shampoo, meal washing, cashmere special detergent) into warm water at about 30℃, then put it into clothes and pat it gently with your hands. If rabbit hair products are stained with dyes, they should be sent to dry cleaners for special treatment and washing. Then wash it several times in warm water at about 40℃ until it is clean. Add a little vinegar or softener to clean water. It is best to put the washed rabbit fur collar into a cloth bag and put it into a washing machine for dehydration 1-2 minutes. Finally, smooth the rabbit fur collar and iron it with a steam iron at 120℃- 140℃. The iron can't directly touch the rabbit fur collar.

. After the rabbit fur collar is set, lay it flat to dry.

The water temperature is 2℃ and 35℃. Wash with your left and right hands, gently squeeze with your hands, and do not rub, knead or twist hard. Secondly, use neutral detergent. Pay attention to the proportion. Generally speaking, the ratio of water to detergent is 100 to 3. Wash, don't let the detergent remain in the rabbit fur collar.

Let's go After washing, you can squeeze the water with a cloth or use a centrifugal dehydrator. However, we should pay attention to three points: first, wrap the sweater and put it into the dehydrator; Second, it should not be too long (2 minutes at most); The third is to put it in a ventilated place after dehydration.

Two. Cleaning method of pigskin

Leather washing can be divided into machine washing and hand washing according to different washing methods; According to the different nature of washing, it can be divided into dry cleaning and wet washing. Machine washing is mainly carried out by leather dry washing machine, while hand washing requires washing tools and washing skills. Mechanical washing usually adopts tetrachloroethylene solvent (also petroleum and fluorine solvents) and low temperature immersion washing. Because mechanical washing is restricted by many laundry equipment conditions, most small and medium-sized laundries in China use manual washing at present. Here are some practical manual cleaning methods for reference only.

Main washing tools: short brush, brown brush, sponge, plastic cleaning ball, towel, cotton ball, washbasin, washing box, air spray gun, portrait air mold, etc.

Main cleaning materials: gasoline, methanol (alcohol), tetrachloroethylene, hydroxide (ammonia water), detergent, hand sanitizer, hydrogen peroxide (hydrogen peroxide), sodium chloride (salt), alum, sodium sulfate (nitric acid injection), vinegar essence, etc.

First, smooth leather is clean.

1. Small area oil pollution treatment

Washing solvent: > 90 # gasoline or tetrachloroethylene. Washing method: put the leather coat flat on the washing table, scrub the greasy part of the leather coat with a sponge or cotton ball dipped in a proper amount of solvent, remove the greasy part, slightly wet the scrubbed part with a towel dipped in hot water at 40-50 degrees Celsius, and dry it in a ventilated and cool place.

2. Large-scale oil pollution treatment

Washing liquid: solution A: 95% alcohol, 25% ammonia, the ratio is 1: 1. Solution B: 25% ammonia water, softener and water in the ratio of 1: 1.

Washing method: put the leather coat flat on the washing table, dip it in solution A for pre-washing, wipe it with a towel while brushing, absorb dirt and dirty liquid, dip it in solution B for secondary cleaning after oil stain removal (the method is the same as above), and put the towel in a ventilated and cool place to dry after cleaning.

3. The skin is light and old.

Washing liquid: solution A: detergent, water, ratio 1: 400, concentration 0.25%-0.3%, water temperature 35-40℃. Solution B: brightener, lubricant and water in the ratio of 1: 1:4.

Washing method: lay the leather coat flat on the washing table, lightly brush it with a brown brush dipped in solution A, and wipe it clean with a towel while brushing. After the oil stain is removed, scrub the wet leather surface with a sponge dipped in solution B, let it stand for 15 minutes, wipe the towel clean and put it in a ventilated and cool place to dry.

4. Denitrification and hardening treatment of leather surface

Washing liquid: solution A: arsenic trioxide, salt and water in the ratio of 1: 1:2 (dissolved and mixed); Usage: 250g of sodium nitrate, 250g of salt and 55g of soft water. Solution B: fatliquor (water-based) slip agent, softener and water, with the ratio of 1:2:2: 10 and the water temperature of 40-45 degrees Celsius. Solution C: formaldehyde and water in the ratio of 1:8 or 1: 10.

Washing method: lay the leather coat flat on the washing table, repeatedly brush the leather coat surface with a brown brush dipped in solution A to make it fully penetrate into the leather coat, let it stand for 30 minutes, repeatedly and evenly scrub the leather coat surface with a plastic cleaning ball dipped in solution B, let it stand for 15 minutes, clean the surface with a towel, put the leather coat on the portrait airplane model, spray solution C evenly on the leather coat surface with a spray gun, and put it in a ventilated and cool place to dry.

Second, suede leather cleaning

Suede leather is generally made of deerskin, deerskin, cowhide, horsehide, pigskin, goatskin and other materials. Suede leather is poor in water resistance, easy to deform, wrinkle or shrink after washing, and easy to produce colored flowers or color complexes, so solvent cleaning is used.

Cleaning solvent: > No.90 gasoline or tetrachloroethylene, commonly used amount: 250ml-500ml.

Washing method: put the leather clothes flat on the washing table, dip the solvent with a short brush and brush lightly according to the fluff. Especially dirty parts are easy to shine and need to be brushed repeatedly. After cleaning, soak the solvent with a sponge for the second time, wipe the surface with a towel and put it in a ventilated and cool place to dry.

Thirdly, aniline leather cleaning.

Aniline leather has strong water absorption and is particularly sensitive to water. It turns black when exposed to water, and becomes discolored, colored or hard after drying. Can't wet wash, usually dry clean with solvent. Similarly, there are double-sided soft leather and foamed leather. Washing solvent: > 90 # gasoline or tetrachloroethylene.

Washing method: put the leather coat flat on the washing table and lightly brush it with a short brush dipped in solvent.

Washing method: lay the leather flat on the washing table, pre-wash it with a brown brush soaked in solvent to make it fully penetrate into the leather, then wash it for the second time with a sponge soaked in solvent, clean the surface with a towel while brushing, and put it in a ventilated and cool place to dry.

2. Wet washing of frosted leather

Washing solvent: detergent, fatliquoring agent (water-based), alcohol and water, the ratio is1:10, and the usual dosage is detergent 150g, fatliquoring agent 150g and alcohol 65450 g. Washing method: put the leather coat flat on the washing table and pre-wash it with a brown brush dipped in solution, especially the dirty part.
