Problems solved by technology

[0004] Aiming at the defects existing in the existing methods for treating textiles with unqualified pH value, the present invention provides a finishing agent for repairing the pH value of textiles. The textiles with unqualified pH value can be repaired by finishing with auxiliary agents without affecting other qualities of textiles. Under the premise, textiles with a pH value exceeding 7.5 can be restored to the range of 4.0 to 7.5 by simple padding and drying, meeting the safety technical specifications and export requirements

[0033] According to formula 1 in Table 1, potassium hydrogen phthalate, potassium chloride, and Pingpinga O-15 were dissolved in water and mixed evenly to prepare a finishing agent for repairing the pH value of textiles.

[0034] The above-mentioned finishing agent for repairing the pH value of textiles was diluted 4 times with water, and the pure cotton fabric was directly padded at room temperature to keep the puffing rate at 100%, and then dried at 105° C. for 3 minutes. According to the GB / T 7573-2002 standard, the pH value of the repaired pure cotton fabric is 6.57 (the original pH value of the pure cotton fabric without repairing agent is 9.91).

[0038] According to formula 2 in Table 2, potassium hydrogen phthalate, potassium chloride, and Pingpinga O-15 were dissolved in water and mixed evenly to prepare a finishing agent for repairing the pH value of textiles.

[0039] The finishing agent for repairing the pH value of textiles prepared above was not diluted, and the pure cotton fabric was directly pad-finished at room temperature, and the liquid rate was kept at 80%, and then dried at 105° C. for 3 minutes. According to the GB / T 7573-2002 standard, the pH value of the repaired cotton fabric is 4.28 (the original pH value of the pure cotton fabric without the repairing agent is 9.70).

[0043] According to formula 3 in Table 3, potassium hydrogen phthalate, potassium chloride, and Pingpinga O-20 were dissolved in water and mixed evenly to prepare a finishing agent for repairing the pH value of textiles.

[0044] The above-mentioned finishing agent for restoring the pH value of textiles was diluted 3 times with water, and the pure cotton fabric was directly padded at room temperature to keep the puffing rate at 100%, and then dried at 105° C. for 4 minutes. According to the GB / T 7573-2002 standard, the pH value of the repaired pure cotton fabric is 4.96 (the original pH value of the pure cotton fabric without repairing agent is 8.11).

Abstract

The invention discloses a finishing agent for restoring the pH value of fabrics, which comprises the following raw materials in percentage by weight: 0.5-12 percent of potassium hydrogen phthalate, 2-30 percent of potassium chloride, 0.5-8 percent of surfactant and the balance of water. By using the finishing agent, the fabrics with the pH value exceeding 7.5 can be restored to have the pH value in range of 4.0-7.5 through simple padding and drying without influencing other qualities of the fabrics, thereby the requirements on the safety technical specification and export can be met. The invention also discloses a preparation method and application of the finishing agent, and has the advantages of simple operation and suitability for industrial production.

Description

technical field [0001] The invention relates to the technical field of textile finishing, in particular to a finishing agent for restoring the pH value of textiles, a preparation method and application thereof. Background technique [0002] The pH value of normal human skin is between 5.5 and 7.0, which is weakly acidic, so as to ensure the balance of resident bacteria and inhibit the invasion of germs. If the pH value of textiles is too different from the pH value of normal human skin, it will irritate the skin, cause skin itching, dermatitis and other diseases, especially for infants and young children. In order to protect the safety of human skin and human health, and to meet the safety requirements of the international market for textiles and expand the export of textiles in my country, it is very important to strictly control the pH value of textiles. [0003] The pH value stipulated in the national mandatory standard GB 18401-2003 "National Basic Safety Technical Spec...
