Preparation method of skin-friendly, bacteriostatic and degradable disposable mask

Abstract

The invention mainly relates to the technical field of mask processing, and discloses a preparation method of a skin-friendly, bacteriostatic and degradable disposable mask, which comprises the following steps of polycarbonate pretreatment, pretreated polycarbonate fiber forming, skin-friendly layer preparation, filter layer preparation, hot press molding and post-treatment. The preparation methodof the skin-friendly, bacteriostatic and disposable mask provided by the invention is simple to prepare, the prepared disposable mask is soft and skin-friendly, the effective filtration and bacteriostatic effects can be achieved, the stiff feeling of an existing disposable non-woven fabric mask is avoided, the wearing comfort is improved, the disposable mask can be quickly and completely biodegraded after the disposable mask is discarded, the generation of residues in the environment is avoided, the pressure of the discarded disposable mask to the environment is reduced, and the self-cleaningability of the environment is recovered and improved.

Description

technical field [0001] The invention mainly relates to the technical field of mask processing, in particular to a preparation method of a skin-friendly, antibacterial and degradable disposable mask. Background technique [0002] With the change of people's living habits and living standards, more and more disposable products have entered people's lives, but while facilitating people's lives, they also put a lot of pressure on the environment. Disposable products are fast-consumables, such as Disposable masks are very convenient to use. You can just throw them away after each use without cleaning, which is very convenient. But the same box of disposable masks will be thrown away soon, so the use of disposable masks can be quickly A large amount of waste is generated, and these discarded disposable masks are difficult to degrade, and are generally incinerated or buried, causing serious pollution to the environment. Therefore, making disposable masks into degradable masks will ...

[0002] With the change of people's living habits and living standards, more and more disposable products have entered people's lives, but while facilitating people's lives, they also put a lot of pressure on the environment. Disposable products are fast-consumables, such as Disposable masks are very convenient to use. You can just throw them away after each use without cleaning, which is very convenient. But the same box of disposable masks will be thrown away soon, so the use of disposable masks can be quickly A large amount of waste is generated, and these discarded disposable masks are difficult to degrade, and are generally incinerated or buried, causing serious pollution to the environment. Therefore, making disposable masks into degradable masks will greatly reduce the pressure on the environment and speed up Environmental recovery; and the texture of disposable masks currently on the market is relatively hard, and it does not fit well with the skin after wearing, and the comfort is poor. Therefore, it is necessary to improve the softness and comfort of the mask to make the mask more skin-friendly

[0003] The existing patent document CN104695135A discloses a biodegradable non-woven fabric and its preparation method, which specifically discloses the use of biodegradable poly(butylene adipate / butylene terephthalate) as a raw material, which is prepared by a melt blown process , although it has a certain degradability, but the degradation cycle is longer, reaching more than 5 years, the degradability is weak, and the pressure of the environment is weak, and the prepared non-woven fabric feels a little hard when used as a mask, and cannot be close to the skin. Fit, can not meet people's use comfort
