Preparation technology for multi-process combined printing

Abstract

The invention discloses a preparation technology for multi-process combined printing The preparation technology comprises the following process steps: grey cloth is subjected to whitening, presetting, dyeing, napping, setting, direct printing, drying, aging, washing, reduction clearing, washing, drying and setting, wherein direct printing comprises steps of discharge printing, burnt-out, gold printing and glue pressing; printing paste for discharge printing is prepared from a disperse dye, 5%-10% of a thickener, 1%-3% of a pH regulator, 1%-3% of a levelling agent and water; discharge paste is prepared from paste, 5%-10% of a thickener, 25%-40% of a discharging agent HB, 1%-3% of a reduction protective agent, 1%-5% of a discharge assistant ZB, 1% of citric acid and water; the burnt-out paste is prepared from 5%-15% of a NaOH alkaline agent, 25%-40% of an alkali-resisting paste, 2%-5% of a penetrant and water. Compared with a traditional technology, the preparation technology omits four times of high-temperature drying processes and four times of washing processes, the process steps are reduced greatly, and the prepared fabric feels good and has better three-dimensional sense.

Description

technical field [0001] The invention relates to a preparation process of printing, in particular to a preparation process of multi-process combined printing. Background technique [0002] At present, polyester supersoft short plush fabric is the first choice for widely used decorative fabrics such as curtains and bedspreads because of its delicate feel. In order to meet the market's requirements for product pattern, color, three-dimensional effect, etc., as well as the application of ever-changing popular elements on fabrics, the printing, discharge dyeing, burnt-out, bronzing, and gluing processes for polyester decorative velvet fabrics have been developed. study in depth. Traditional printing, discharge dyeing, burnt-out, bronzing, and gluing processes are relatively mature, but if they are distributed according to process requirements, the entire processing process will be lengthy, which wastes time and energy, reduces production efficiency, and greatly improves producti...

AI Technical Summary

Problems solved by technology

Traditional printing, discharge dyeing, burnt-out, bronzing, and gluing processes are relatively mature, but if they are distributed according to process requirements, the entire processing process will be lengthy, which wastes time and energy, reduces production efficiency, and greatly improves production. Cost, and each process of printing, discharge dyeing, burnt-out, bronzing, and lamination needs to go through a high-temperature drying and washing process, which makes the high-temperature treatment time in the entire process too long, affecting the effect and feel of the cloth surface
