Embodiment 1

[0018] After the cowhide is fleshed, delimed, and washed with softening water, the liquid ratio is 30%; taking the hide as 100 parts by mass, add 30 parts of water, control the temperature at 20°C, add 6 parts of sodium chloride, and control the Baumé degree 6.5, After reacting for 20 minutes, add 0.3 parts of 10wt% dilute formic acid, add 0.4 parts of 10wt% dilute formic acid after 10 minutes, add 0.8 parts of 5wt% dilute sulfuric acid after reacting for 10 minutes, and then use the same Add sulfuric acid 2 times in the same way, and react for 10 minutes each. After the third dilute sulfuric acid is added, the pH value is controlled at 2.3 and then reacted for 60 minutes, and then the pH value is controlled at 3.0, and the reaction is continued for 45 minutes to complete pickling; Add 5 parts of chromium powder into the pickling skin drum, react for 60 minutes, control the temperature at 24°C, and control the pH value at 2.5, then add 0.5 parts of magnesium oxide Blancorol HR-...

Embodiment 2-5

[0024] After the cowhide is fleshed, delimed, and washed with softening water, the liquid ratio is 30%; taking the hide as 100 parts by mass, add 30 parts of water, control the temperature at 20±2°C, add 6 parts of sodium chloride, and control the wave Mido 6.0~7.0, after reacting for 20 minutes, add 0.3 parts of 10wt% dilute formic acid, add 0.4 parts of 10wt% dilute formic acid after 10 minutes, add 0.8 parts of 5wt% diluted sulfuric acid after reacting for 10 minutes, and react for 10 minutes Then add sulfuric acid twice in the same way, and react for 10 minutes each. After the third dilute sulfuric acid is added, the pH value is controlled at 2.3 for another 60 minutes, and then the pH value is controlled at 3.0±0.1, and the reaction is continued for 30~60 minutes. Minutes to complete pickling; add 5 parts of chromium powder to the above pickling skin drum, react for 60 minutes, control the temperature at 22~25°C, and control the pH value at 2.5±0.1, then add 0.5 parts of m...

Abstract

The invention relates to a production process of flame retardant trim cow leather. The production process comprises the steps of fleshing, deliming, softening, tanning, shaving, retanning, dyeing, stuffing, drying, milling and finishing, wherein the step of tanning comprises the successive procedures of salting, pickling and chrome powder tanning; and the retanning, the dyeing, the stuffing, the low-temperature airing drying and the finishing adopt characteristic processes. The flame retardant trim cow leather is compact and uniform in body, is excellent in toughness, is good in resilience and is excellent in flame retardance, and the quality can be controlled easily in the production process; after the leather is stretched in a seat or is used, the seat can be kept in an optimal form and comfort because of excellent resilience of the leather; and under the precondition of guaranteeing the softness and flame retardance, the water resistance, the sweat resistance, the color fastness to rubbing and the wear resistance of a coating layer are effectively improved.

Description

technical field [0001] The invention relates to the technical field of tanning, in particular to a production process of flame-retardant cowhide interior leather. Background technique [0002] At present, the seats of mid-to-high-end cars and high-speed rail VIP compartments are covered with high-grade genuine leather. This kind of leather interior leather is usually made of cowhide after fleshing, deliming, softening, tanning, retanning, dyeing, fatliquoring, drying, softening, Cowhide interior leather generally has the following problems: [0003] 1. The product has certain flammability and cannot be extinguished immediately after ignition; [0004] 2. The combustion produces a lot of smoke, which seriously affects the safety of passengers in emergency situations; [0005] 3. The product emits more organic matter, which affects the air quality in the car. Contents of the invention [0006] The technical problem to be solved by the present invention is to develop a pro...
