Embodiment Construction

[0021] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0022] The dyeing process of non-woven fabrics is carried out according to the following steps:

[0023] 1. The non-woven fabric to be dyed is unwound from the unwinder and immersed in the dyeing solution of the dyeing vat for dyeing; the temperature of the dyeing solution is 95-98°C, and the residence time of the non-woven fabric in the dyeing solution is 3-8 seconds;

[0024] 2. The dyed non-woven fabric is washed in clean water, generally for 3-8 seconds, and then dewatered;

[0025] 3. The colored non-woven fabric that has been dehydrated is dried; the drying temperature is 130-150 ° C, and the drying heating time is 3-8 seconds; then it is rolled.

[0026] The non-woven fabric is unwound from the unwinding machine and is directly spread on the mesh belt in circulation, and enters the dyeing, cleaning and water removal processes under the ...

Abstract

The invention relates to a non-woven fabric dyeing process and a non-woven fabric dyeing production line, aiming to make the process and the production line have the characteristics of high production efficiency and good dyeing quality. The invention adopts the technical proposal of the non-woven fabric dyeing process, and comprises the steps: a non-woven fabric to be dyed is soaked into a dyeing solution of a dyeing vessel for dyeing; afterwards, the non-woven fabric is cleaned with clear water, then the water is removed; and drying is performed and then the non-woven fabric is rolled into coils. The dyeing, cleaning and water removing of the non-woven fabric are performed under the holding of the mesh belt. The non-woven fabric dyeing production line comprises an uncoiling machine, a dyeing vessel, a cleaning vessel, a squeezing part, a drying cylinder group and a coiling part; the net belt is driven by a plurality of rollers arranged in parallel, and penetrates through the dyeing vessel, the cleaning vessel and the squeezing part and winds back to perform the circulating motion, so as to hold the non-woven fabric to be processed together; at least two pairs of mill rollers are arranged at the squeezing part in parallel, so as to extrude the non-woven fabric to remove the water; a plurality of dying cylinders are arranged at the drying cylinder group in parallel for heating and drying the non-woven fabric; and a cloth roller is arranged at the coiling part to roll the dried non-woven fabric.

Description

technical field [0001] The invention relates to a textile dyeing process and textile dyeing equipment, in particular to a non-woven fabric dyeing process and a non-woven fabric dyeing production line. Background technique [0002] With the continuous growth of the economy and the continuous improvement of people's living standards, the demand for non-woven fabrics, especially colored non-woven fabrics, is increasing; especially all kinds of light, thin and high-end clothing require non-woven fabrics as linings. The woven fabric is kept the same color as the clothing fabric. However, because the non-woven structure of the non-woven fabric determines its low wet strength, it cannot be dyed by existing various textile dyeing machines. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiency of above-mentioned background technology, provide a kind of non-woven fabric dyeing process and non-woven fabric dyeing production line, this ...
