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

The invention relates to a spinning printing and dyeing green environment-friendly edible acidic body and a preparation method thereof and belongs to the technical field of spinning printing and dyeing. The acidic body comprises, by weight parts, 26-36 parts of deionized water, 4.6-6.8 parts of potassium peroxymonosulfate, 10-16 parts of white vinegar and 56-68 parts of citric acid. The spinning printing and dyeing green environment-friendly edible acidic body is non-toxic, safe, environmentally friendly and bright. When the spinning printing and dyeing green environment-friendly edible acidic body is used, a soaping agent does not be added. Metal ions in water, such as calcium ions, magnesium ions, arsenic ions, lead ions and mercury ions, can be complexed, so that the product is safe and non-toxic. The surface of a printed and dyed textile is not white. The spinning printing and dyeing green environment-friendly edible acidic body has high dirt-removing capacity and can prevent pollution by mixed colors. The treated textile is good in color fastness and does not shade. Secondary pollution to other products by the treated textile in the using process can be effectively prevented.
