Abstract

The invention belongs to the field of textiles, and specifically relates to a formaldehyde purifying agent and a using method thereof. The formaldehyde purifying agent is composed of a formaldehyde removing agent and a formaldehyde photocatalytic decomposition agent, the formaldehyde removing agent comprises powder and a medicament, the mass ratio of the powder to the medicament is 3-10. Specificcomponents and a formula are provided, and the using mode of the formaldehyde removing agent is further provided. The problem of poor formaldehyde removal effect in the prior art is solved, polyvinylacetate is used as a remover and is subjected to a polycondensation reaction with formaldehyde after alcoholysis, rapid removal of formaldehyde is achieved, a good removal effect is achieved, meanwhile, a photocatalytic decomposition agent is added to achieve a continuous formaldehyde decomposition function, and the air purification effect is achieved.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a formaldehyde scavenger for textile fabric treatment and a use method thereof. Background technique [0002] Formaldehyde is a colorless gas with a pungent odor, easily soluble in water, alcohol and ether. Formaldehyde has a wide range of uses in industry. It is often used in textiles, dyes, leather, resins, paints, plastics, rubber, pharmaceuticals, explosives, etc. Therefore, formaldehyde pollution mainly comes from the above products. The harm of formaldehyde to the human body is mainly manifested in the following aspects: formaldehyde can combine with the protein in the protoplasm of somatic cells, change the internal structure of the protein and solidify, so it has biocidal power. At low concentrations, it initially irritates the mucous membranes of the eyes, and at high concentrations, it irritates the upper respiratory tract, causing coughing, chest tightness, a sen...
