Abstract

The invention discloses a reclaimed leather production technology which comprises the following specific steps: smashing waste leather by a defoathering machine; grinding the smashed waste leather by a grinding machine; transferring the smashed waste leather into an extraction pool for extracting leather fibers; adding crosslinking fibers and resin, stirring by a stirring machine, and preparing slurry; adding the slurry into a flow box to enable the slurry to flow to a forming machine from the flow box gradually, and processing the slurry by the forming machine; squeezing a formed product by a squeezing machine to remove water; conveying the product subjected to squeeze water removal into a drying machine for drying, and obtaining a qualified reclaimed leather finished product when the moisture content is lower than 5 percent. The reclaimed leather production technology has the advantages of simplicity and the like.

Description

A kind of regenerated leather production technology

Technical field

The present invention relates to a kind of regenerated leather production technology, be applied to the production and processing field of regenerated leather.

Background technology

Regenerative leather has the feature of corium and PU concurrently, is leatherware fabric very general now, and traditional regenerated leather production technology is not only backward, loaded down with trivial details, cost is high, be unwell to and extensively promote the use of, the mass ratio of the regenerated leather produced in addition is poor, and therefore the production technology of regenerated leather is badly in need of improving.

Summary of the invention

For solving the defect of prior art, the invention discloses that a kind of technique is simple, the regenerated leather production technology of good product quality.

The invention discloses a kind of regenerated leather production technology, concrete steps are as follows:

Step one: utilize unhairing machine to be pulverized by Leather Waste;

Step 2: the Leather Waste after pulverizing is transported in pulp storage tank, utilizes fiberizer to polish to broken worn-out leather;

Step 3: the broken worn-out leather after step 2 process is transferred in extraction pond and extract hide fiber;

Step 4: hide fiber is joined in slurrying pond, and add cross filament, resin, use mixer to stir, produce out slurry;

Step 5: slurry is joined in head box, slurry gradually by flowing on forming machine in head box, by forming machine machine-shaping;

Step 6: use squeezer to dewater to the squeezing of shaping product;

Step 7: the product after squeezing being dewatered is sent in dryer and carries out drying and processing, uses ice detector to carry out moisture measurement to regenerated leather, moisture lower than 5% time, namely obtain qualified regenerated leather finished product.

By adopting above-mentioned steps, regenerated leather production technology technique of the present invention is simple, and cost is low, is suitable for extensively promoting the use of, and the regenerated leather quality produced is good, long service life.
