Multifunctional neutralizing acid agent for laundry dragon and its manufacturing process

Abstract

The invention discloses a multifunctional neutralizing acid agent for laundry dragons and a manufacturing process thereof. The neutralizing acid agent comprises the following components in mass percent: trisodium methylglycine diacetate 1-5%, diethyl ether with a purity of 40%. Triaminepentaacetic acid 2‑6%, fluorescent whitening agent 0.01‑0.5%, sulfamic acid 12‑20%, citric acid 1‑5%, oxalic acid 1‑5%, hydrofluoric acid 0.01‑0.2%, ethanol 2 ‑6%, the balance is deionized water. The multifunctional neutralizing acid agent for laundry dragon provided by the invention is simple and practical to manufacture, has good neutralizing performance, and can quickly and synchronously complete peracid neutralization, softening, antistatic and whitening treatments. The neutralizing acid agent provided by the invention not only neutralizes alkaline substances, but also effectively removes calcium, magnesium, iron ions and other dirt deposits deposited on public textiles, effectively avoiding graying and yellowing of textiles after repeated washing , so that the whiteness value can be kept > 70 degrees for a long time; after using the neutralizing acid agent, the pH value of public textiles in wet state can be 5-7, so as to avoid skin irritation caused by public textiles after washing.

Description

technical field [0001] The invention relates to the technical field of industrial neutralizing acid agents, in particular to a multifunctional neutralizing acid agent for laundry dragons and a manufacturing process thereof. Background technique [0002] "Laundry dragon" is the abbreviation of a tunnel washing machine. After the main washing and rinsing are completed, the washing dragon immediately enters the process of peracid neutralization. The neutralizing acid agent used in the process of peracid neutralization is mainly used for public use. Peracid neutralization of textiles after washing and rinsing. [0003] At present, most of the neutralizing acids used in washing machines on the market are oxalic acid, sodium fluorosilicate, citric acid, etc. Although these acid agents have their own functional characteristics, their neutralization effect is not good, and the pH value after neutralization is relatively high (pH value Greater than 7), there are the following proble...

AI Technical Summary

Problems solved by technology

[0003] At present, most of the neutralizing acids used in washing machines on the market are oxalic acid, sodium fluorosilicate, citric acid, etc. Although these acid agents have their own functional characteristics, their neutralization effect is not good, and the pH value after neutralization is relatively high (pH value Greater than 7), there are the following problems: one, part of the alkaline substance will remain in the fabric, and along with the moisture evaporation fabric drying process, the alkali concentration remaining in the fabric increases, and the excessive pH value will not only damage the fabric fiber, but also cause damage to the fabric. Stimulate human skin and cause skin itching; second, the pH value is too high, in addition to being unable to effectively neutralize the residual alkali, it cannot remove acid-soluble dirt and deposits containing calcium, magnesium and other metal ions attached to the surface of the fabric. And it accumulates with the increase of washing times, and with the accumulation of residues, it gradually leads to graying, yellowing and poor hand feeling of the fabric; third, when the towel fabric is overacid neutralized, the pH value is high, which greatly reduces The adsorption of the softener thus reduces the softening antistatic effect
