Embodiment Construction

[0008] The manufacturing method of the washing-resistant suede leather of the present invention is realized by the following schemes:

[0009] 1. Preparing the skin embryo: Place the selected 100 parts by weight of suede skin in the drum.

[0010] 2. Backwater: Add 100 parts by weight of water at 45°C, 0.5 parts by weight of AP-C degreasing agent, and 0.3 parts by weight of SAF non-ionic rewetting agent into the drum with crusts, and rotate for 120 minutes.

[0011] 3. Retanning: Drain the water, add 80 parts by weight of 35°C water, 0.3 parts by weight of formic acid, and rotate for 10 minutes to make the pH value 3.3-3.5; then add 0.6 parts by weight of chromium powder and 1.5 parts by weight Rotate for 90 minutes; add 1.0 parts by weight of sodium formate and rotate for 30 minutes; add 0.4 parts by weight of baking soda and rotate for 20 minutes; finally add 0.4 parts by weight of baking soda and rotate for 20 minutes. Overnight, make the pH value 3.9-4.1.

[0012] 4. Washing: ...

Description

Technical field [0001] The invention relates to a method for processing suede leather, in particular to a method for manufacturing suede leather that is resistant to washing. Background technique [0002] Suede leather is a skin with a fluffy effect on the surface of the leather. The product made of suede leather has good air permeability, elegant appearance and wear resistance, but its disadvantage is that it is easy to get dirty and difficult to maintain. Especially in a bad environment, the suede is easy to absorb dust, and when it meets with water, it will cause the fluff to fall down, fade and deform. Since it cannot be washed with water, maintenance and cleaning are very troublesome. Summary of the invention [0003] The purpose of the present invention is to provide a method for manufacturing a water-washable suede leather. The suede leather produced by this method can be washed directly in water without fading and deformation. [0004] The technical scheme of the present...
