Description

Technical Field

[0001] This invention pertains to methods for treating hazardous substances in the textile industry, specifically relating to a method for removing APEO from textiles. Background Technology

[0002] Alkylphenol polyoxyethylene ethers (APEOs) are currently the main representatives of widely used nonionic surfactants. APEOs have excellent wetting, penetrating, emulsifying, dispersing, solubilizing, and detergency properties, and are widely used in the processing and manufacturing of products in the detergent, personal care, textile, printing, synthetic rubber, and plastics industries. Their primary applications are in detergent products and textile auxiliaries. APEOs are commonly used in textile processing as scouring agents, wetting agents, penetrating agents, enzyme preparations, printing pastes, adhesives, coating agents, leveling agents, waterproofing agents, various emulsions, and dispersants, with over 80% being nonylphenol polyoxyethylene ethers (NPEOs).

[0003] The ecotoxicity issues of APEO mainly involve its safety and biodegradability. Safety includes acute toxicity, aquatic toxicity, skin irritation, teratogenicity, and mutagenicity. Given its significant toxicity, the European Commission's Chemicals Regulatory Agency (CCAR) included APEO in the REACH regulation, requiring that its content in textiles not exceed 100 mg / kg. The Oeko-Tex Standard 100 issued by the International Association for Research and Testing in Eco-textiles requires that the total content of alkylphenols and alkylphenol polyoxyethylene ethers in textiles not exceed 100 mg / kg. Current Chinese industry standards FZ / T73005 and FZ / T 73018 both stipulate that the APEO content in textiles must not exceed 100 mg / kg.

[0004] However, the reality is that, due to the lack of mandatory national standards, APEO is still widely used in my country's textile industry. Once manufacturers use APEO-containing auxiliaries to produce textile fabrics or even finished garments, they will face returns from brand owners, export trade barriers, and domestic inspections, resulting in significant economic losses. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a method for removing APEO from textiles, which can clean textiles with excessive APEO content to below the acceptable limit, without damaging the original softness, color fastness and other properties of the textiles.

[0040] To illustrate the superior effect of the APEO removal agent for textiles of the present invention, the present invention also provides the following comparative examples.

[0041] Comparative Example 1

[0042] By changing the degree of polymerization of lauryl alcohol polyoxyethylene ether in Example 1 above to 11-16, with an average degree of polymerization of 14, and keeping other conditions unchanged, textile APEO removal agent 8 was obtained.

[0043] Comparative Example 2

[0044] The degree of polymerization of fatty alcohol polyoxyethylene ether in Example 1 was changed to 10-13, with an average degree of polymerization of 12, while other conditions remained unchanged, to obtain textile APEO removal agent 9.

[0045] Comparative Example 3

[0046] By removing diethylene glycol butyl ether from the component in Example 1 above, and keeping other conditions unchanged, we obtain APEO removal agent 10 for textiles.

[0047] Comparative Example 4

[0048] By removing polyvinylpyrrolidone from the component in Example 1 above, while keeping other conditions unchanged, we obtain APEO removal agent 11 for textiles.

[0049] Comparative Example 5

[0050] By removing the hydroxyethyl cellulose component from Example 1 above, while keeping other conditions unchanged, we obtain textile APEO remover 12.

[0051] Comparative Example 6

[0052] The amount of polyvinylpyrrolidone in Example 1 was changed to 0.5 parts, while other conditions remained unchanged, to obtain APEO removal agent 13 for textiles.

[0053] Comparative Example 7

[0054] The amount of hydroxyethyl cellulose in Example 1 was changed to 0.2 parts, while other conditions remained unchanged, to obtain textile APEO removal agent 14.

[0055] APEO removal methods for textiles

[0056] Step 1: Immerse the textiles to be treated in water to obtain a mixture, add the textile APEO removal agent, wherein the mass ratio of the textiles to water is 1:10, and the amount of textile APEO removal agent to water is 4 g / L. Wash at 50°C for 30 minutes, then centrifuge and dry the textiles. The textile APEO removal agents used are 14 types prepared in the above examples and comparative examples, which are used to treat the textiles to be treated. The textiles to be treated are textiles that have undergone dyeing and finishing processes using dyeing and finishing auxiliaries. For comparative illustration, the textiles used in Example 1, Comparative Examples 1-7, and the blank control are the same textiles containing the same amount of APEO.

[0057] Step 2: Immerse the textiles treated in Step 1 in water at 50°C for 20 minutes, wherein the mass ratio of the textiles treated in Step 1 to the water in Step 2 is 1:15. After immersion, centrifuge and spin dry the textiles, and wait for testing.

[0058] Performance testing and effect evaluation

[0059] Fourteen textile samples were treated with the aforementioned 14 APEO removal agents according to the APEO removal methods described above. The APEO values ​​of the textiles before and after treatment in Examples 1-7 and Comparative Examples 1-7 were determined using the LC-MS method specified in GB / T 23322-2018 "Determination of Surfactants in Textiles - Alkylphenols and Alkylphenol Polyoxyethylene Ethers". The results are shown in the table below:

[0060] Table 1. APEO Residue Detection Results

[0061]

[0062] As shown in the table above, the textiles treated with the APEO removal agent of this application in Examples 1 to 7 have an APEO content of less than 50 mg / kg, which meets the relevant domestic and international regulatory requirements.

[0063] Comparing the textiles treated with Example 1 and Comparative Example 1, it was found that the degree of polymerization of lauryl alcohol polyoxyethylene ether in Example 1, which was 7-10, had a better APEO removal effect than the degree of polymerization of lauryl alcohol polyoxyethylene ether in Comparative Example 1, which was 11-16. This indicates that when the degree of polymerization of lauryl alcohol polyoxyethylene ether is 7-10, it can better displace APEO from textiles and effectively remove APEO.

[0064] Comparing the textiles treated with Example 1 and Comparative Example 2, it was found that the degree of polymerization of fatty alcohol polyoxyethylene ether in Example 1, which was 5-7, had a better APEO removal effect than that of fatty alcohol polyoxyethylene ether in Comparative Example 2, which had a degree of polymerization of 10-13. This indicates that when the degree of polymerization of fatty alcohol polyoxyethylene ether is 5-7, it can better displace APEO from textiles and effectively remove APEO.

[0065] Comparing the textiles treated in Example 1 and Comparative Example 3, it was found that the addition of diethylene glycol butyl ether in Example 1 resulted in a better APEO removal effect in the prepared textile APEO remover, which could effectively remove APEO.

[0066] Comparing the textiles treated with Example 1 and Comparative Example 4, it was found that Comparative Example 4 had a worse effect on removing APEO, and the textiles treated with the APEO treatment agent prepared in Comparative Example 4 had a worse softness, which would affect their subsequent performance.

[0067] Comparing the textiles treated with Example 1 and Comparative Example 5, it was found that Comparative Example 5 was less effective at removing APEO, and the textiles treated with the APEO treatment agent prepared in Comparative Example 5 showed color fading, which affected the color fastness of the fabric.

[0068] Comparing the textiles treated in Example 1 and Comparative Example 6, it was found that the increased amount of polyvinylpyrrolidone in Comparative Example 6 resulted in a poorer APEO removal effect. This indicates that excessive use of polyvinylpyrrolidone can affect the synergistic effect of other components on APEO removal.

[0069] Comparing the textiles treated with Example 1 and Comparative Example 7, it was found that the increased amount of hydroxyethyl cellulose in Comparative Example 7 resulted in a poorer APEO removal effect. This indicates that excessive hydroxyethyl cellulose can affect the synergistic effect of other components on APEO removal.

[0070] Comparing Example 1 with washing with water but without using the APEO removal agent of this application, Example 1 showed better APEO removal.
