Problems solved by technology

Therefore, the invisible powder is still harmful to the human body
In addition, the invisible powder needs to be sealed and kept before use, otherwise it is very easy to be vaporized, and it cannot be placed in a sealed room for a long time. After entering the sealed room, it is easy to cause lung diseases. The invisible powder is more harmful than profit

preparation example Construction

[0016] The preparation method of this chalk powder comprises the following steps:

[0017] 1. By weight percentage, calcium sulfate 60%-65%, salicylic acid 15%-17%, calcium oxide 15%-16%, zinc stearate 3.2%-5.0%, calcium stearate 2%-5% %, palmitic acid 0% ~ 10%, amino acid 0% ~ 1%, release agent 0.2% ~ 0.3%, heating and stirring at a constant temperature of 80 ~ 90 degrees to dissolve completely, forming a uniform colorless transparent solution or milky white solution , stop heating, and keep the solution warm at 20-25 degrees;

[0018] 2. Soak the prepared chalk in the above solution, take it out after 15-50 minutes, and let it dry naturally to prepare the chalk.

[0019] The scribing powder of the present invention is improved on the basis of the existing invisible scribing powder. Combining with the traditional scribing powder, the main component of the developed scribing powder is calcium sulfate. Since calcium sulfate is equipped with other auxiliary materials, it is ve...

Embodiment 1

[0021] The calcined powder comprises 60% of calcium sulfate, 15% to 17% of salicylic acid, 15% to 16% of calcium oxide, 3.2% to 5.0% of zinc stearate, 2% to 5% of calcium stearate, palm Acid 0% to 10%, amino acid 0% to 1%, release agent 0.2% to 0.3%, and the rest are impurities.

[0022] Calcium sulfate, salicylic acid, calcium oxide, zinc stearate, calcium stearate, palmitic acid, amino acid, and release agent are heated and stirred at a constant temperature of 80 to 90 degrees to completely dissolve them in percent by weight, and Uniform colorless and transparent solution or milky white solution, stop heating, keep the solution warm at 20-25 degrees; soak the prepared marking powder in the above solution, take it out after 15-50 minutes, and dry it naturally to complete the marking pink.

Embodiment 2

[0024] The calcined powder comprises 65% of calcium sulfate, 15% to 17% of salicylic acid, 15% to 16% of calcium oxide, 3.2% to 5.0% of zinc stearate, 2% to 5% of calcium stearate, palm Acid 0% to 10%, amino acid 0% to 1%, release agent 0.2% to 0.3%, and the rest are impurities.

[0025] Calcium sulfate, salicylic acid, calcium oxide, zinc stearate, calcium stearate, palmitic acid, amino acid, and release agent are heated and stirred at a constant temperature of 80 to 90 degrees to completely dissolve them in percent by weight, and Uniform colorless and transparent solution or milky white solution, stop heating, keep the solution warm at 20-25 degrees; soak the prepared marking powder in the above solution, take it out after 15-50 minutes, and dry it naturally to complete the marking pink.

Abstract

The invention discloses a tailor's chalk which comprises the following components in percentage by weight: 60-65% of calcium sulfate, 15-17% of salicylic acid, 15-16% of calcium oxide, 3.2-5.0% of zinc stearate, 2-5% of calcium stearate, 0-10% of palmitic acid, 0-1% of amino acid, 0.2-0.3% of a demolding agent and the balance of impurities. The tailor's chalk disclosed by the invention is improved on the basis of the existing invisible tailor's chalk, and is researched and developed with the main component of calcium sulfate by combining the conventional tailor's chalk; and when the tailor's chalk is applied to a dress material, calcium sulfate is attached to the dress material, and because calcium sulfate is matched with other auxiliary materials, the main component namely calcium sulfate can fall off only by beating forcibly for a while, so that the tailor's chalk is very easy to remove.

Description

technical field [0001] The invention relates to production equipment in the garment industry, in particular to a chalk. Background technique [0002] Cutting refers to cutting the material according to a certain size when sewing clothes. Cutting is the most critical process in the garment manufacturing process. The style and size are all realized in this process. Once cut, the style and size are basically difficult to change. Therefore, in the early stage of cutting, it is necessary to draw the style and size with chalk. [0003] Traditional scribing powder is difficult to remove after painting. Therefore, the current design has invisible scribing powder, which has the characteristic of disappearing automatically or disappearing immediately after ironing: gasification. The gasification time is closely related to the intensity of the marking, the air temperature and humidity, and can be adjusted according to the intensity of the marking. Generally, it can disappear automat...
