Abstract
The invention discloses a formaldehyde catching agent for fabrics. The formaldehyde catching agent for fabrics comprises the following components by weight percent: 7%-15% of 2-imidazolidone, 20%-30% of polyalcohol, 0.3%-1% of a pH modifier, and 60%-75% of water. A preparation method of the formaldehyde catching agent comprises the steps of (1) mixing the 2-imidazolidone with water, and stirring at room temperature for 30-60 minutes so as to dissolve the 2-imidazolidone completely; and (2) adding the polyalcohol into the solution of the step (1), stirring at room temperature for 20-40 minutes so as to dissolve the polyalcohol, adding the pH modifier, stirring to regulate the pH of the solution to be 6.0-8.0. The preparation method of the formaldehyde catching agent is simple, and the prepared formaldehyde catching agent can effectively remove free aldehydes substances in fabrics.
Description
Technical field
The present invention relates to the formaldehyde catching agent that a kind of fabric is used, the invention still further relates to a kind of preparation method of this formaldehyde catching agent.
Background technology
Formaldehyde pollution problem has related to each corner in life, and serious threat health has caused showing great attention to of people.In textiles manufacture process, owing to can discharging a certain amount of free formaldehyde on textiles, content of formaldehyde has become an important safety index of textiles pollution monitoring.But, existing formaldehyde catching agent on market, its effect of removing formaldehyde is also not obvious, and fabric, after formaldehyde catching agent is processed, still has residual formaldehyde and discharges, and is detrimental to health.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of effective fabric formaldehyde catching agent of aldehyde of catching is provided, the present invention also provides a kind of preparation method of this formaldehyde catching agent.
For achieving the above object, the present invention is by the following technical solutions:
The formaldehyde catching agent that fabric is used, by weight percentage, composed of the following components: 2-imidazolidinone: 7～15%; Polyalcohol: 20～30%; PH adjusting agent: 0.3～1%; Water: 60～75%.
Preferably: by weight percentage, composed of the following components: 2-imidazolidinone: 7%; Polyalcohol: 21%; PH adjusting agent: 0.5%; Water: 71.5%.
Preferably: by weight percentage, composed of the following components: 2-imidazolidinone: 15%; Polyalcohol: 25%; PH adjusting agent: 0.8%; Water: 59.2%.
Preferably: described polyalcohol is one or more in diethylene glycol, ethylene glycol, propylene glycol and butanediol.
Preferably: described pH adjusting agent is one or more in citric acid, natrium citricum and glacial acetic acid.
Another object of the present invention, a kind of preparation method of formaldehyde catching agent as above, comprises the following steps:
1) 2-imidazolidinone is mixed with water, stirring and dissolving 30～60 minutes under normal temperature, dissolves completely to 2-imidazolidinone;
2) in the solution in step 1), add polyalcohol, under normal temperature, stirring and dissolving, after 20～40 minutes, adds pH adjusting agent, stirs pH value of solution is adjusted to 6.0-8.0.
Beneficial effect of the present invention is, formaldehyde catching agent of the present invention, and preparation technology is simple, and the formaldehyde catching agent of fabric through making can not only effectively be removed the free formaldehyde discharging on fabric, but also fabric is had to certain soft effect after processing.
