Problems solved by technology

[0016] Disadvantages of the prior art: According to the leather thickness requirements, the existing leather processing technology uses a machine for smoothing, which is an indispensable process. The excess leather fiber tissue is cut off, and repeated smoothing is carried out (one The peel needs to be processed more than twice on the machine

Embodiment Construction

[0034] In the present invention, white skin embryos with a thickness between 1.1 mm and 0.8 mm are used as raw materials for processing, and the thickness of the finished product is: 0.1 mm to 0.4 mm. The specific processing steps are as follows:

[0035] Step 1: select the raw material sheepskin (white leather embryo). To make high-quality sheepskin calligraphy and painting paper, it is necessary to select white leather embryos with a thickness between 1.1mm and 0.8mm, and the thickness is uniform, and there should be no scratches or scars left by parasites on the leather to ensure product quality.

[0036] Step Two: Soak light tanning. Put the selected white leather embryos into the tanning solution and soak for light tanning. The temperature is controlled at 10°C-15°C. After 1-2 hours, take out and drain, and proceed to the next step of filling light tanning.

[0037] The ingredients of the tanning solution are: water (H 2 O), and mixed rare earth chloride (Ms-ReCl 3 ·6H...

Abstract

The invention relates to parchment for writing and painting. The parchment for writing and painting is characterized in that processed sheepskin with the thickness between 1.1 mm and 0.8 mm is used as a raw material and is processed, and the thickness of a finished product is 0.1 mm-0.4 mm; and the specific processing steps include gentle tanning through soaking, filling of a slurry clearing agent, shaping and trimming, and wet-drying. The parchment for writing and painting has the advantages that the texture and properties of the sheepskin are changed, the parchment for writing and painting is light, thin like paper, flexible, stiff and compact in structure and has the good properties such as good folding strength and good toughness; the technical problem that the breakage rate in existing leather processing is high is solved; according to processing technical parameters of the processed sheepskin, the thickness is smaller than or equal to 0.4 mm, the ductility is improved by 15%, and the rate of finished products is 100%; manufacturing cost is lowered, no pollution is caused to the environment in the processing procedure, and technological operation is safe.

Description

technical field [0001] The invention relates to a sheepskin calligraphy and painting paper, which belongs to the technical field of leather processing. Background technique [0002] The sheepskin processed according to the existing leather processing technology is called "white leather embryo", and its production and processing technology is as follows: [0003] Step 1: Raw hide treatment process [0004] 1. Rawhide soaking in water: This process has a great impact on product quality, and the operation method must be strictly implemented. The purpose of soaking in water is to restore the raw hide to the state of fresh hide, and remove part of the soluble protein and attached sundries. The temperature of immersion depends on the type of raw hide, generally 15-18°C is suitable, if the softening of the hide is slow below 18°C, bacteria are easy to multiply above 20°C. The soaking time is generally 5-6 hours in running water. If the dry skin or salt-dried skin has been stored...
