Embodiment 1

[0046] A dyeing process for imitation leather, comprising the following steps:

[0047] Step S1, unwinding the gray cloth through a KT-TJ-1800A unwinding machine.

[0048] Step S2, cleaning: add 3 tons of clear water, 2 kg of high-temperature degreaser (i.e. high-temperature degreaser JS-202) and 2 Mix 1 kg of deoiling spirit (that is, special effect deoiling spirit SXY-123), and then put the unrolled gray fabric into the overflow dyeing machine through the cloth guide frame, raise the temperature to 130°C, and keep it warm for 20 minutes for cleaning.

[0049] Step S3, decontamination and rinsing: lower the temperature to 100°C, discharge the water in the overflow dyeing machine under normal pressure, control the temperature of the clean water at 30-40°C, and then add clean water to rinse for 3 times.

[0050] Step S4, the gray cloth is exported from the overflow dyeing machine, and transferred to the drier for dehydration and drying for 20 minutes, and then opened by a TB-T...

Embodiment 2

[0059] A kind of dyeing process of imitation leather, and the difference of embodiment 1 is: in step S5, at first add 100 kilograms of clear waters, 1 kilograms of softening agent and 4 kilograms of fluffing agents in the tank and mix evenly, then at normal temperature will The gray cloth obtained in step S4 is put into the above-mentioned water tank for pretreatment, and then dried with a roller, and then put into an oven for drying treatment at a speed of 25-28m / min.

Embodiment 3

[0061] A dyeing process for imitation leather, the difference from Example 1 is: in step S7, after the overflow dyeing machine is cooled to 100°C, the overflow dyeing machine is first opened for sample processing, when the imitation leather When the dyeing of the velvet is consistent with the standard sample, add water to the overflow dyeing machine and rinse it 3 times, and get the imitation leather velvet after removing the water;

Abstract

The invention discloses a dyeing process of imitation leather, which belongs to the technical field of imitation leather processing, and its technical points include gray cloth unwinding, cleaning, decontamination and rinsing, dehydration and opening, drying, napping, dyeing, dehydration and opening, and shaping After drying, cooling and shaping, and rolling into the warehouse, the finished imitation leather can be obtained. By adjusting the sequence of each step, the invention can not only improve the dyeing effect and dyeing uniformity of the imitation leather, but also further optimize the process and improve the efficiency. Secondly, the pretreatment of the fluffing agent and the softening agent can make the fluffing effect of the gray cloth better in the later process of napping, and at the same time increase the softness of the gray cloth. In addition, when drying and setting the temperature in two steps, not only can the excess water in the imitation leather be removed, but also the effect of adjusting the width of the imitation leather can be achieved, so that the hair surface of the imitation leather is more uniform and smooth.

Description

technical field [0001] The invention belongs to the technical field of imitation leather processing, more specifically, it relates to a dyeing process of imitation leather.
