Non-woven fabric dyeing process and non-woven fabric dyeing production line

Abstract

The invention discloses a non-woven fabric dyeing production line. The non-woven fabric dyeing production line comprises a dyeing pool and a winding frame; a winding motor is arranged on the winding frame; an output end of the winding motor is connected with a winding roller and drives non-woven fabric to be connected in a winding mode; a tensioning assembly for adjusting dyeing tension of the non-woven fabric is arranged on the inner wall of one side of the dyeing pool; the other side of the dyeing pool is provided with a cleaning and scraping assembly for cleaning and scraping excess dye onthe non-woven fabric; and a pair of drying bins for drying the dye on the non-woven fabric is arranged between the dyeing pool and the winding frame. According to the non-woven fabric dyeing production line, through the arranged tensioning assembly, it is ensured that the non-woven fabric enters or moves out of dye in the optimal tensioning state, the dyeing uniformity of the non-woven fabric is improved, and the redundant dye on the non-woven fabric can be removed in combination with the scraping effect of the cleaning and scraping assembly; and the dyeing uniformity of the dye on the non-woven fabric is further improved, and the phenomenon that the local dyeing thickness of the non-woven fabric is inconsistent is avoided.

Description

technical field [0001] The invention relates to the technical field of cloth processing, in particular to a non-woven fabric dyeing process and a non-woven fabric dyeing production line. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics are moisture-proof, breathable, flexible, light in weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. Features such as polypropylene pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing. After the production and processing of non-woven fabrics, in order to obtain different colors, it is necessary to The dyeing production line performs dyeing processing on non-woven fabrics. [0003] When the existing non-woven fab...

AI Technical Summary

Problems solved by technology

[0003] When the existing non-woven fabric dyeing production line dyes the non-woven fabric, due to the large span of the non-woven fabric during the conveying process, the non-woven fabric will loosen, resulting in uneven dyeing of the dye on the non-woven fabric. 1. It is easy for dyes to accumulate locally on non-woven fabrics, resulting in waste of dyes and reducing the dyeing quality of non-woven fabrics
