Embodiment 1

[0027] The two outer non-woven fabric layers 101 in this embodiment are made of polylactic acid fibers through a hot-air process, and the polylactic acid content of the outer non-woven fabric layers 101 is 100%. The denier of polylactic acid fiber is 1.2d-2d. The non-woven fabric made by the hot air process has the characteristics of fluffy and soft, and the mask has a good overall feel and is comfortable to wear.

[0028] The middle non-woven fabric layer 102 is made by the melt-blown process, and the melt index of the middle non-woven fabric layer 102 is 200-1500g / 10min when processed by the melt-blown process. By the electrostatic electret method, the middle non-woven fabric layer 102 has a relatively High filtration efficiency, placed in the mask has a very good filtering effect.

[0029] The polylactic acid content of the middle non-woven fabric layer 102 is greater than 90%, the melt-blown non-woven fabric has a small pore size and a high porosity, and the ultra-fine fi...

Embodiment 2

[0031] The outer non-woven fabric layer 101 of this embodiment is made by a spun-bonding process, and the content of polylactic acid is 100%. After melting, the polylactic acid particles are extruded and spun by a metering pump to obtain spinning, and the spinning is shaped by a hot rolling roll, and finally reinforced to obtain the outer non-woven fabric layer 101 .

[0032] The processing technology of the middle non-woven fabric layer 102 in this embodiment is the same as that in Embodiment 1.

Embodiment 3

[0034] The outer non-woven fabric layer 101 in this embodiment is made by a spunbonding process, polylactic acid particles and degradable PP particles are blended, and after melting, they are extruded and spun by a metering pump to obtain spinning, and the spinning is formed by a hot rolling roll. Finally, the outer non-woven fabric layer 101 is obtained through reinforcement. The mass ratio of polylactic acid particles and degradable PP particles is 2:1.

[0035] The degradable PP (polypropylene) of this embodiment can be prepared by using the existing technology. The processing technology of the middle non-woven fabric layer 102 in this embodiment is the same as that in Embodiment 1.

Abstract

The invention discloses a degradable mask, and relates to the technical field of articles of daily use. The degradable mask comprises a mask body and fixing bands, the fixing bands are fixed to the two sides of the mask body, the mask body comprises two outer non-woven fabric layers and a middle non-woven fabric layer arranged between the two outer non-woven fabric layers, the middle non-woven fabric layer is made through a melt-blowing technology, the mass content of polylactic acid in the outer non-woven fabric layer and the mass content of polylactic acid in the middle non-woven fabric layer are both 50% or above. The polylactic acid is used as a main raw material of the mask, the problem of environmental pollution of an existing mask can be solved, beneficial effects are brought to sustainable development of the earth, people do not need to worry that disposable hygienic products harm the environment due to the degradable mask, and the polylactic acid has the advantages of being good in weather fastness and high in strength retention rate at the normal temperature.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a degradable mask. Background technique [0002] At present, the global resource and environmental crisis is becoming more and more serious. Both developed and developing countries in the world are facing problems such as shortage of natural resources and serious environmental pollution. With the rapid development of the economy, people's living standards are gradually improving, and the market for disposable sanitary products continues to develop. People's requirements for disposable sanitary products are also getting higher and higher. Consumers not only hope that disposable sanitary products can not only meet the basic functions , also hope that disposable sanitary products can be more safe, comfortable and green. [0003] The existing masks are traditional general masks. Due to the frequent and repeated outbreaks of the epidemic, masks have become a must-have for e...
