Abstract

The composition of the invented mark-hiding chalk includes (wt%) 60%-70% of benzoic acid, 20%-21% of salicylic acid, 3.2%-5.0% of zinc stearate, 1.9%-7.0% of calcium stearate, 0%-7.0% of cetylic aicd, 0%-0.3% of aminophthalein and 0.3% of demoulding agent. Its chalking mark can be automatic eliminated in 2-7 days, and said formula can be regulated time for eliminating chalking mark according to the user's requirements, and if said chalking mark is ironed, it can be quickly removed.

Description

technical field [0001] The invention relates to a scribing powder for marking cloth, in particular to a hidden scribing powder, which belongs to the field of chemical materials. technical background [0002] The traditional scribing powder is made of mineral powder. The scribing on the cloth cannot be removed, and it must be cleaned to remove it. It is labor-intensive, and the traces cannot be completely removed, which affects the quality of clothing. In the clothing export industry, there have even been many requests for return. Through literature search, it is found that Chinese Patent No. 92232956.7 is a real-type patent named "Craft Cutting Drawing Chalk", but it only provides a structure for cutting and making drawing chalk, and does not solve the shortcoming that the chalk marks are difficult to clean. A further literature search has not found any relevant technology related to the formulation of the cutting powder for cutting that can solve the above problems. Conte...
