Fabric finishing device by using formaldehyde and method for processing woven fabric by using fabric finishing device

Abstract

The invention relates to a fabric finishing device by using formaldehyde. The fabric finishing device comprises a reactor, a gaseous formaldehyde generation device and an air washing device, wherein the reactor comprises a reactor body, a reactor sealing door, a fabric roll shaft set, a roll shaft set driving device and a reactor heating device; the fabric roll shaft set comprises a plurality of fabric roll shafts; the gaseous formaldehyde generation device comprises a paraformaldehyde reactor and a heating device; the paraformaldehyde reactor is sealed and communicated with a reaction space; the heating device is used for heating paraformaldehyde arranged in the paraformaldehyde reactor and releasing formaldehyde gas to a reaction space; the air washing device comprises an air washing chamber and an air washing pipe system; and the air washing pipe system comprises an air inlet pipe and an air outlet pipe. The processing method disclosed by the invention comprises a discharge step, a vapor deposition step, an air washing step, a receiving step and the like. According to the fabric finishing device and the processing method disclosed by the invention, due to the adoption of a sealing heating and waste gas recovering scheme, the aim of finishing the fabric by safely and efficiently using formaldehyde gas is achieved.

Description

technical field [0001] The invention relates to a fabric finishing device and a fabric processing method thereof, in particular to a fabric finishing device using formaldehyde gas and a fabric processing method thereof, belonging to the field of fabric finishing equipment. Background technique [0002] Fabric finishing refers to the process of fabric processing in order to improve the quality of fabric after scouring, bleaching, dyeing and printing. It is a necessary process before the finished fabric. The finishing and processing of fabrics can change the appearance and mechanical properties of fabrics and endow them with some special functions, which can greatly improve the appearance and use of fabrics. Early fabric finishing was mainly to obtain temporary finishing effects. With the development of the chemical industry, the increase in synthetic fiber production and the deepening understanding of fiber structure and performance, fabric finishing has changed from simply e...
