Embodiment

[0010] Embodiment: a formaldehyde repellent for textile fabrics, each component is by weight, water: glycerin: alkali: urea: ethylenediamine=100: 1~5: 10~20: 20~50: 20~50;

[0011] The alkali is one or more of sodium hydroxide, potassium hydroxide and sodium bicarbonate.

[0012] A preparation method of formaldehyde repellent for textile fabrics, by weight, water: glycerin: alkali: urea: ethylenediamine=100: 1~5: 10~20: 20~50: 20~50 to weigh each component, Add them to the reaction kettle in turn, and stir for 4 to 8 hours at a temperature of 60°C to 80°C.

[0013] By using the invention to treat textile fabrics whose formaldehyde content exceeds the standard, more than 90% of the formaldehyde can be removed, and at the same time free formaldehyde will not be generated. For example, the pollution degree content of a piece of textile printing fabric is 200PPM. After mixing 1kg of formaldehyde repellent of the present invention with 4kg of clear water, soak and clean the textil...

Abstract

The invention provides a formaldehyde exterminator for textile fabrics. The formaldehyde exterminator is characterized in that the weight ratio of water to glycerine to alkalis to urea to ethylene dimine is 100:(1-5):(10-20):(20-50):(20-50). A preparation method is characterized by weighing the components, adding the components to a reactor in turn and stirring the components to react for 4-8 hours at the temperature of 60-80 DEG C. An application method is characterized by uniformly mixing the prepared formaldehyde exterminator with water in a weight ratio of 1:(2-4) and then putting the mixture in the textile fabrics with over standard formaldehyde at the temperature of 40-60 DEG C, after washing the textile fabrics for 15-60min, drying the textile fabrics. The formaldehyde exterminatorand the preparation and application methods have the following beneficial effects: the content of formaldehyde can be freely adjusted by adopting the product and processes provided by the invention to treat the textile fabrics; different textile fabrics and different formaldehyde contents can meet the requirements of the international and domestic standards after treatment; and most importantly, the original physical and chemical properties of the products such as the textile fabrics can not be changed after treatment.

Description

Technical field: [0001] The invention relates to the technical field of textile fabric production, and more specifically relates to a formaldehyde repellent for textile fabrics and a preparation and application method thereof. Background technique: [0002] Formaldehyde has been classified as a human carcinogen by the International Agency for Research on Cancer and a possible carcinogen by the U.S. Environmental Protection Agency. In the textile industry, in order to improve the color fastness, color fixing agents are used in the textile dyeing process. The fixing agent is mainly a resinous cyanamide-formaldehyde condensation polymer, which is likely to allow formaldehyde to enter fabrics and clothing. Formaldehyde-containing self-contained cross-linking agents are also often used in the pigment printing process, so that formaldehyde remains in the printing part. Some clothing fabric processing factories may leave formaldehyde on clothing fabrics during the process of usin...
