Abstract

The invention relates to the technical field of cashmere processing, and concretely relates to a cashmere sanding treatment technology. The technology comprises the following steps: 1, adding cashmere and formic acid to a rotary drum, adjusting the pH value, carrying out rotation treatment, adding an HN solution to the rotary drum, and carrying out rotating retanning treatment; 2, adding a retanning agent magnopal DP to the rotary drum, rotating, adding sodium formate to the rotary drum, adjusting the pH value, rotating, adding a cationic fatting agent to the rotary drum, rotating, adding a cationic resin retanning agent to the rotary drum, rotating, adding a dye solution to the rotary drum, rotating, adding a dye fixing agent to the rotary drum, and carrying out stationary treatment; and 3, carrying out natural hanging air-drying, sanding by adopting 800 mesh sandpaper, dedusting, and warehousing. Cashmere processed through the cashmere sanding treatment technology has irregular and color-fantastic floral designs, a dual or multiple color effect, and a very aesthetic appearance.

Description

technical field [0001] The invention relates to the technical field of cashmere processing, in particular to a cashmere sanding treatment method.
