Embodiment 1

[0052] The preparation technology of two-layer leather with strong explosive force comprises the following steps:

[0053] Step 1, one return water:

[0054] Put the two-layer leather material in the drum for one backwater to obtain one backwater leather, wherein, the one backwater process is: add the following components according to the weight of the leather to the drum in turn for one backwater: 190% water, 0.4% soda ash and 0.1% degreasing agent, wherein, the temperature of the primary return water is 48°C, after 55 minutes of the primary return water, drain the drum, then add water to wash and drain.

[0055] Step 2, secondary water return:

[0056] The first backwater leather obtained in step 1 is subjected to secondary backwater to obtain the second backwater leather, wherein, the secondary backwater process is: sequentially add the following components according to the weight of the leather material to the drum for secondary backwater: 190% water, 0.4% soda ash and 0...

Embodiment 2

[0073] The preparation technology of two-layer leather with strong explosive force comprises the following steps:

[0074] Step 1, one return water:

[0075] Put the two-layer leather material in the drum for one backwater to obtain one backwater leather, wherein, the one backwater process is: add the following components according to the weight of the leather to the drum in turn for one backwater: 200% water, 0.5% soda ash and 0.2% degreasing agent, wherein, the temperature of the first return water is 45°C, after the first return water for 60 minutes, drain the drum, then add water to wash and drain.

[0076] Step 2, secondary water return:

[0077] The first backwater leather obtained in step 1 is subjected to secondary backwater to obtain the second backwater leather, wherein, the secondary backwater process is: sequentially add the following components according to the weight of the leather material to the drum for secondary backwater: 200% water, 0.5% soda ash and 0.15...

Embodiment 3

[0094] The preparation technology of two-layer leather with strong explosive force comprises the following steps:

[0095] Step 1, one return water:

[0096] Put the two-layer leather material in the drum for one backwater to obtain one backwater leather, wherein, the one backwater process is: add the following components according to the weight of the leather to the drum in turn for one backwater: 210% water, 0.6% soda ash and 0.3% degreasing agent, wherein, the temperature of the primary return water is 50°C, and after 65 minutes of primary return, the drum is drained, and then water is added for washing and draining;

[0097] Step 2, secondary water return:

[0098] The first backwater leather obtained in step 1 is subjected to secondary backwater to obtain the second backwater leather, wherein, the secondary backwater process is: sequentially add the following components according to the weight of the leather to the drum for secondary backwater: 210% water, 0.6% soda ash...

Abstract

The invention discloses a preparation technology of two-layered leather with high explosive force, and belongs to the technical field of leather. The preparation technology of the two-layered leather with the high explosive force comprises the following steps of primary water returning, secondary water returning, retanning and leather basifying, neutralizing, dyeing and greasing, color fixing, water washing, drum removing, drying, softening, leather fluffing and light beating. An independently researched and developed green and environment-friendly agent is added in all the steps, and the two-layered leather with the high explosive force is obtained through a safe and controllable preparation technological process; and the two-layered leather is stable in performance, high in tearing and pulling force resistant performance and high in explosive force, leather face fibers are thin, a leather body is full, and a velvet feeling is achieved.

Description

technical field [0001] The invention belongs to the technical field of leather, and in particular relates to a preparation process of two-layer leather with strong blasting force. Background technique [0002] In some special places, it is often necessary to use specially treated materials or materials with special properties. For example, car leather seat cushions and leather binding materials need to use high-strength leather, while ordinary leather does not have high strength. It is even more impossible to achieve the performance of strong explosive force. Leather on the market is generally used for belts, leather sofas and car leather seat cushions, but its performance is often difficult to achieve the desired effect. [0003] The Chinese invention patent with the application number of 201510641755.4 discloses a production method of high-strength automotive leather with crack resistance, which includes the following steps: take soft leather, and then go through primer c...
