example 1

[0025] Wash the egg shell with deionized water and dry it naturally, grind it and pass through a 60-mesh sieve to obtain egg shell powder, mix the egg shell powder, deionized water and 10% nitric acid solution by mass fraction, and carry out stirring treatment, that is Obtain a mixed solution, filter to obtain a filtrate, adjust the pH value of the filtrate to obtain a mixed solution A; mix stearic acid and deionized water, and carry out constant temperature stirring to obtain a mixed solution B, which is mixed in a mixed solution with a mass ratio of 1:1. Add mixed solution A to B, and continue to stir for 10 minutes to obtain mixed solution C. Add 1 mol / L sodium hydroxide solution to mixed solution C, stir at a constant temperature of 50°C for 30 minutes, filter to obtain filter residue, and wash the filter residue. Drying treatment, cooling to room temperature, to obtain calcium stearate; take benzoic acid, gypsum powder, egg shell powder, calcium stearate, polyethylene wax,...

Abstract

The invention relates to a preparation method for environment-friendly tailor's chalk capable of fading color, and belongs to the technical field of garment supplies. According to the preparation method, light benzoic acid which is easy to sublimate is used as a main raw material of the tailor's chalk, and the environment-friendly tailor's chalk capable of fading color has good performance indexes, such as drawing smoothness, glossiness, color fading effect, color fading time, appearance and the lie; sodium dodecyl benzene sulfonate and Tween 80 are used as surface active agents, and the sodium dodecyl benzene sulfonate can play effects of a dispersing agent. According to the preparation method, the main raw materials comprise grease, alkali liquor, water, an adhesive, a coloring agent andan regulating agent, all the main raw materials are mutually combined, refined, saponified, salted out, washed, subjected to alkali-out and formed to prepare the environment-friendly tailor's chalk capable of fading color. The environment-friendly tailor's chalk capable of fading color contains hydrophilic and oleophilic components, and the hydrophilic components can make some oil dirt on the hands of a user or remaining on cloth floated and dissolved into water. The environment-friendly tailor's chalk capable of fading color is easy to dissolve into the water without polluting the surrounding environment, and the aim of environment protection is easily achieved.

Description

technical field [0001] The invention relates to a preparation method of fadeable environmental protection chalk, which belongs to the technical field of clothing products. Background technique [0002] Scribing powder is a powder used to mark the position of cutting, curling and threading in garment making. According to the effect of use, scribing powder can be divided into two categories: invisible scribing powder and ordinary scribing powder. Hidden chalk can be divided into automatic sublimation and disappearing chalk, heat-disappearing chalk (dry ironing with electric iron) and water-disappearing chalk (can be wiped off with water). Ordinary chalk is non-disappearing chalk, which can be divided into clay chalk, wax chalk and fat chalk. [0003] At present, there is still the phenomenon of using ordinary scouring powder in China. Most of the common scouring powder is made of gypsum powder, talcum powder, and clay, and then added with pigments such as ultramarine blue an...
