Abstract

The present invention relates to a processing technique of genuine leather fiber cotton, which is characterized in that the leftover materials of genuine leather are sorted, separated according to color and sheared, and then, water, a penetrating agent, slaked lime, a softening agent and ammonium sulfate required are added to the leftover materials of genuine leather in different periods of time, and finally, the leftover materials of genuine leather are rotated clockwise and counterclockwise in a rotary drum device to be treated by raising to obtain genuine leather fiber cotton, and genuine leather fiber cotton is dried and made to be fluffy to obtain genuine leather fibre products whose fiber length is at least 16 millimeters. The leftover materials of genuine leather are recovered and processed into genuine leather fibre cotton by the scientific processing technique of the present invention, so that genuine leather fibre cotton yarn can be spun into cloth to satisfy industrial and living requirements.

Description

Processing technology of corium fabric suede and products thereof

[technical field]

The present invention relates to corium fabric suede process technology, particularly be the invention of corium fabric suede processing technology.

[background technology]

In the prior art, there are many leftover pieces can not regeneration after the cladding processing, causing the great loss of cladding resource, how the leftover pieces of animal cladding are obtained utilizing to greatest extent and reduce or overcome waste, is that the Leather Engineering technical staff studies the problem that waits to solve always.

[summary of the invention]

In view of the problem that known technology exists, the technical problem to be solved in the present invention is fiber suede to be processed in the recycling of corium leftover pieces spin cotton and weave cloth, and to be applied to industry and life, reaches the reasonable resources configuration.In order to achieve the above object, the present invention adopts following technology to finish: a kind of corium fabric suede processing technology is characterized in that it includes following steps:

A) the corium leftover pieces are selected materials, color separation, are cut material;

B) corium of choosing 100 parts of weight ratios is cut material, adding temperature is 38 ℃-45 ℃, weight ratio is 200～250 parts a water, add weight ratio simultaneously and be 1.5 ~ 2 parts bleeding agent, drop into turn clockwise continuously napping 60 ~ 90 minutes of rotary drum equipment, be rotated counterclockwise napping again after 10 minutes, seal 20 ~ 24 hours, then;

C) to add temperature be that 38 ℃ of-45 ℃ of weight ratios are 50 parts water to the compound after will sealing, and adds weight ratio simultaneously and be 5～6 parts white lime, and the rotation napping seals 35 ~ 40 hours once more after 120 minutes continuously in rotary drum equipment;

D) compound in the step c) is dropped into rotary drum equipment again, add weight ratio and be 50 parts water, add weight ratio simultaneously and be 2 ~ 3 parts softening treasured, rotation at 30 minutes per intermittences napping once continues 5 hours;

E) adding weight ratio in rotary drum equipment is 2 ~ 3 parts sulfate of ammoniac, 0.5 part bleeding agent, and adds 200 parts of normal-temperature water, rotates napping more continuously 60 ~ 90 minutes, then;

F) sewage is got rid of, added weight ratio again and be 500 ~ 600 parts water purification, rotated napping continuously 30 minutes, last;

G) it is dry above-mentioned mixed liquor to be gone out drum, drops into rotary drum equipment rotation napping again and carries out the fluffy corium fabric suede that just becomes after 15 ~ 25 hours.

In the above-mentioned processing technology, rotate napping once 30 minutes per intermittences in the step d), and the wherein preceding 20 minutes nappings that turn clockwise in rotary drum equipment were rotated counterclockwise napping in back 10 minutes in rotary drum equipment.

In the above-mentioned processing technology, to go out the dry mode of drum can be to dry or dry to mixed liquor in the step g), its bake out temperature≤50 ℃.

By the made corium fabric suede product of above-mentioned processing technology, fibre length 〉=16 behind the rotation napping millimeter.

Processing technology of the present invention, the leftover pieces of animal cladding have been obtained utilization to greatest extent, reduced waste to leftover pieces, make resource reach reasonable configuration, simultaneously, corium fabric suede product according to this processes obtains can be made into cloth with its spinning, to satisfy the needs of industry and life.

[specific embodiment]

Again embodiment is described in detail below.

This kind corium fabric suede processing technology, it includes following steps: the corium leftover pieces are selected materials, color separation, cut material; Choose the corium of 100 parts of weight ratios and cut material, adding temperature is 38 ℃-45 ℃, weight ratio is 200～250 parts a water, add weight ratio simultaneously and be 1.5 ~ 2 parts penetrating agent JFC, drop into turn clockwise continuously napping 60 ~ 90 minutes of rotary drum equipment, be rotated counterclockwise napping again after 10 minutes, seal 20 ~ 24 hours, then; It is that 38 ℃ of-45 ℃ of weight ratios are 50 parts water that compound after the sealing is added temperature, adds weight ratio simultaneously and be 5～6 parts white lime, and the rotation napping seals 35 ~ 40 hours once more after 120 minutes continuously in rotary drum equipment; At this moment, the pH value of its mixed liquor is 11 ~ 12, above-mentioned compound is dropped into rotary drum equipment again, the adding weight ratio is 50 parts a water, add weight ratio simultaneously and be 2 ~ 3 parts softening precious OR, rotation at 30 minutes per intermittences napping once, the wherein preceding 20 minutes nappings that in rotary drum equipment, turn clockwise, the back was rotated counterclockwise napping in 10 minutes in rotary drum equipment, continue 5 hours; Adding weight ratio in rotary drum equipment is 2 ~ 3 parts sulfate of ammoniac, 0.5 part penetrating agent JFC, and adds 200 parts of normal-temperature water, rotates napping more continuously 60 ~ 90 minutes, then; Sewage is got rid of, added weight ratio again and be 500 ~ 600 parts water purification, rotated napping continuously 30 minutes, last; It is dry that above-mentioned mixed liquor is gone out drum, and its drying mode can be to dry or dry, and its bake out temperature is 45 ℃, drops into rotary drum equipment again and rotate napping and carry out the fluffy corium fabric suede that just becomes after 15 ~ 25 hours.According to the made corium fabric suede product of above-mentioned processing technology, the fibre length behind the rotation napping should be more than or equal to 16 millimeters, with convenient weaving.
