Problems solved by technology

[0002] At present, the types of dyeing acids used in the textile printing and dyeing process include: sulfuric acid, synthetic acid (dyeing acid), industrial grade glacial acetic acid; safety
Moreover, there are unsafe factors for the human body in the use of the above-mentioned dyeing acid in the textile printing and dyeing industry; for example, during the operation of the worker, the above-mentioned dyeing acid splashes on the worker's skin and causes burns, scalds leave permanent scars, and when it splashes into the worker's eyes. permanent disability
What is even more worrying is that the current medical textile products (medical cotton, medical gauze, medical cotton balls, medical cotton swabs, etc.) prepared with the above-mentioned dyed acids usually contain heavy metals, such as arsenic, lead, and mercury, which cannot reach food-grade safety. level

Embodiment 1

[0026] Deionized water 26kg, potassium hydrogen persulfate 4.6kg, white vinegar 10kg and citric acid 56kg.

[0027] Add deionized water into the reaction kettle, start stirring and heat up to 46°C; add potassium hydrogen persulfate, stir and keep warm for 26 minutes, then continue to heat up to 100°C; stir and keep warm for 28 minutes, then cool down to 46°C; add white vinegar, stir After 6 minutes, slowly add citric acid; after adding citric acid, close the reaction kettle, stir and keep warm for 48 minutes; the acidic body can be obtained. The obtained acidic body will not crystallize even if it is left for 96 days when it is exposed to the air at normal temperature.

Embodiment 2

[0029] Deionized water 26kg, potassium hydrogen persulfate 6.8kg, white vinegar 16kg and citric acid 68kg.

[0030] Add deionized water into the reaction kettle, start stirring and heat up to 46°C; add potassium hydrogen persulfate, stir and keep warm for 26 minutes, then continue to heat up to 100°C; stir and keep warm for 28 minutes, then cool down to 46°C; add white vinegar, stir After 6 minutes, slowly add citric acid; after adding citric acid, close the reaction kettle, stir and keep warm for 48 minutes; the acidic body can be obtained. The obtained acidic body will not crystallize even if it is left for 96 days when it is exposed to the air at normal temperature.

Embodiment 3

[0032] 26kg of deionized water, 4.6kg of potassium hydrogen persulfate, 16kg of white vinegar and 60kg of citric acid.

[0033] Add deionized water into the reaction kettle, start stirring and heat up to 46°C; add potassium hydrogen persulfate, stir and keep warm for 26 minutes, then continue to heat up to 100°C; stir and keep warm for 28 minutes, then cool down to 46°C; add white vinegar, stir After 6 minutes, slowly add citric acid; after adding citric acid, close the reaction kettle, stir and keep warm for 48 minutes; the acidic body can be obtained. The obtained acidic body will not crystallize even if it is left for 96 days when it is exposed to the air at normal temperature.

Abstract

Provided are an environmentally-friendly food grade acidic body for textile printing and dyeing and a preparation method therefor, belonging to the technical field of textile printing and dyeing. The raw materials in part by weight of the acidic body are: 26-36 parts of deionized water, 4.6-6.8 parts of potassium peroxymonosulphate, 10-16 parts of white vinegar and 56-68 parts of citric acid. The preparation method comprises: dissolving potassium peroxymonosulphate in deionized water in a reaction kettle, then raising the temperature to 100-120°C, maintaining the temperature for 28 minutes and then reducing the temperature to 46°C; and then adding white vinegar, stirring same for 6 minutes, further adding citric acid, closing the reaction kettle and maintaining the temperature for 48 minutes. The acidic body is non-toxic, safe, environmentally friendly and edible.

Description

technical field [0001] The invention relates to a green environment-friendly edible grade acid body for textile printing and dyeing and a preparation method thereof, belonging to the technical field of textile printing and dyeing.
