Problems solved by technology

There are some blood tendons on the bottom of the second-layer suede leather. When the second-layer wet-blue leather is processed to make the second-layer suede leather by traditional production technology, it is easy to appear the phenomenon of bursting tendons. Once the leather surface is bursting, it will cause bursting tendons. The leather in the part cannot be used, which will not only reduce the utilization rate of the leather, but also need to trim and remove the leather with bursting ribs, and the removed scraps cannot be recycled

Embodiment 1

[0032] The manufacture method of non-explosive tendon two-layer suede leather specifically comprises the following steps:

[0033] Step 1, rewetting: take the wet blue hide, weigh it, place it in a drum, and mix 250% of water (water temperature 50°C), 0.5% degreasing agent Eusanpon OC, 0.95 Add 0.08% water-soaking agent Eusapon W and 0.08% water-soaking enzyme Basozym S20 into the drum, adjust the pH to 9.5, and add 1.5% softening enzyme Basozym B10 after running for 60 minutes. Drain to get wet leather;

[0034] Step 2, retanning: add 120% water, 0.5% formic acid, and 2.0% retanning agent (foaming polymer TJ-R6034) to the drum according to the mass of the wet blue hide, run for 30 minutes, and then add 3.0% chromium powder, run for 120 minutes, drain, inject water for washing, and drain again to obtain retanned leather;

[0035] Step 3, neutralization: according to the mass of wet blue hides, add 150% of water, 2.5% of sodium formate, and 1.5% of neutralized tannin Tamol NA...

Embodiment 2

[0042] The manufacture method of non-explosive tendon two-layer suede leather specifically comprises the following steps:

[0043] Step 1, rewetting: take the wet blue hide, weigh it, place it in a drum, and mix 200% water (water temperature 45°C), 0.4% degreasing agent Eusanpon OC, 0.9 Add 0.05% water soaking agent Eusapon W and 0.05% water soaking enzyme Basozym S20 into the drum, adjust the pH to 9, run for 55 minutes, add 1.3% softening enzyme Basozym B10, run for 140 minutes, drain, inject water for washing, and then Drain to get wet leather;

[0044] Step 2, retanning: add 110% water, 0.4% formic acid, and 1.5% retanning agent (foaming polymer TJ-R6034) to the drum according to the mass of the wet blue hide, run for 25 minutes, and then add 2.5% chromium powder, run for 115 minutes, drain, inject water for washing, and then drain to obtain retanned leather;

[0045] Step 3, neutralization: according to the mass of wet blue hides, add 140% of water, 2.2% of sodium forma...

Embodiment 3

[0052] The manufacture method of non-explosive tendon two-layer suede leather specifically comprises the following steps:

[0053] Step 1, rewetting: take the wet blue hide, weigh it, place it in a drum, and mix 300% water (water temperature 50°C), 0.6% degreaser Eusanpon OC, 1.0% according to the mass of the wet blue hide Add 0.1% water-soaking agent Eusapon W and 0.1% water-soaking enzyme Basozym S20 into the drum, adjust the pH to 10, and add 1.7% softening enzyme Basozym B10 after running for 65 minutes. Drain to get wet leather;

[0054] Step 2, retanning: add 130% water, 0.6% formic acid, and 2.5% retanning agent (foaming polymer TJ-R6034) to the drum according to the mass of the wet blue hide, run for 35 minutes, and then add 3.5% chromium powder, run for 125 minutes, drain, inject water for washing, and drain again to obtain retanned leather;

Abstract

The invention relates to blood-vein-exposure-proof double-layer suede and a manufacturing method thereof and belongs to the technical field of leather manufacturing. The manufacturing method of the vein-exposure-proof double-layer suede comprises the following steps: rewetting; retanning; neutralizing; filling; dyeing; grease feeding; acid immobilizing; drying; hanging and airing; softening in a vibrating way; leather grinding; and milling. According to the manufacturing method provided by the invention, a manufacturing technique and used chemical materials are improved so that the phenomenonof exposure of blood veins at the bottom surface of the leather is effectively prevented, and the leather yield is increased. Meanwhile, liquid chemical materials used in all steps are relatively goodin water solubility and good in environmental friendliness; and the manufacturing method provided by the invention is mild in condition, convenient to operate and suitable for being popularized and applied to the field of leather manufacturing.

Description

technical field [0001] The invention belongs to the technical field of leather production, and in particular relates to a two-layer suede leather with non-explosive ribs and a production method thereof. Background technique [0002] Suede is also known as suede. Suede has good wear resistance and comfort, and its application is becoming more and more extensive. There are some blood tendons on the bottom of the second-layer suede leather. When the second-layer wet-blue leather is processed to make the second-layer suede leather by traditional production technology, it is easy to appear the phenomenon of bursting tendons. Once the leather surface is bursting, it will cause bursting tendons. The leather in the part cannot be used, which will not only reduce the utilization rate of the leather, but also need to trim and remove the leather with bursting ribs, and the removed scraps cannot be recycled. Therefore how to improve the production process of traditional two-layer suede...
