Printing process of velvet fabric

Abstract

The invention discloses a printing process of a velvet fabric, which comprises the steps of (1) carrying out preliminary filtration, specifically, enabling workshop production printing wastewater to automatically flow into a collecting tank; (2) carrying out wastewater regulation, specifically, conveying the wastewater filtered out from the collecting tank into a wastewater regulating tank through a pump to regulate the water quality and the water quantity; (3) carrying out sedimentation, specifically, conveying the water in the wastewater regulating tank into a sedimentation tank through a pump; (4) conducting degradation, specifically, conveying the water treated in the sedimentation tank into a hydrolysis acidification tank through a pump; and (5) conducting oxidation, specifically, enabling the water treated in the hydrolysis acidification tank to automatically flow into a contact oxidation tank. According to the printing process of the velvet fabric, water in the wastewater regulating tank can be subjected to water quality and water quantity regulation work through a coagulation reaction tank and a flocculation tank, and subsequently regulated water sequentially passes through the sedimentation tank, the hydrolysis acidification tank and the contact oxidation tank to be subjected to processing treatment work, so that chromaticity removal, conversion of degraded organic matters and degradation and oxidation of water are facilitated.

Description

technical field [0001] The invention relates to the technical field of velvet fabrics, in particular to a printing process for velvet fabrics. Background technique [0002] The forming methods of velvet fabrics mainly include brushing, brushing, sanding, flocking, sand washing, shrinking, etc., by using gray cloths such as plain weave, twill, serge, etc., to make relative movement with the raising roller on the wire raising machine to make the fabric Fluffy fluff is produced on the surface, which makes the fluff products have a more beautiful appearance, and can be used for printing processing. [0003] In the printing process of velvet fabrics in the market today, the purification of wastewater generated after the printing of velvet fabrics is not complete enough, and at the same time, it is prone to clogging, which leads to the need for frequent maintenance of equipment in the purification process, reducing the Overall work efficiency, therefore, we just propose the metho...
