Dyeing technology for non-woven fabric production

Abstract

The invention provides a dyeing technology for non-woven fabric production. Dyeing equipment for non-woven fabric production is used in the dyeing technology. The equipment comprises mounting plates, a draining device and a drying device; the two mounting plates are vertically distributed in a front-back symmetrical mode; and the draining device and the drying device are sequentially arranged between the mounting plates from bottom to top. The dyeing technology can solve the following problems in the dyeing process of non-woven fabric production: a, a non-woven fabric needs to be dyed in the production process, mostly the non-woven fabric is directly soaked in a dyeing jar for dyeing and then is taken out, at the moment, the non-woven fabric absorbs a large amount of dyeing liquid and needs to be subjected to draining treatment, and traditional draining is mainly performed by extruding the non-woven fabric, so that the draining effect is poor and the non-woven fabric cannot be effectively dewatered; and b, a traditional non-woven fabric drying mode mainly adopts a heating pipe to directly dry the non-woven fabric, local overheating exists, the non-woven fabric is damaged, and mostly the non-woven fabric is subjected to single-side drying, so that the efficiency is low.

Description

technical field [0001] The invention relates to the technical field of non-woven fabric production, in particular to a non-woven fabric production and dyeing process. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, needle-punched cotton, etc., are composed of directional 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. Most of them are made of polypropylene pp pellets as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. Non-woven products are rich in color, bright and bright, fashionable and environmentally friendly, widely used, beautiful and elegant, with various patterns and styles, and are light in weight, environment...

Problems solved by technology

[0005] The invention provides a dyeing process for the production of non-woven fabrics, which can solve the following problems in the production and dyeing process of non-woven fabrics: a. Non-woven fabrics need to be dyed during the production process, and most of them are directly soaked in dyeing vats for dyeing , and then take it out, and at this time the non-woven fabric will absorb a large amount of dyeing solution, and it needs to be drained. The traditional draining is mainly done by extruding the non-woven fabric. The draining effect of this method is poor, and the non-woven fabric cannot be drained Effective water removal; b. The traditional non-woven fabric drying method is mainly to dry directly through the heating tube, there is local overheating, resulting in damage to the non-woven fabric, and most of them are only dried on one side, and the efficiency is low
