Problems solved by technology

However, PBS plastic has high strength and low toughness, its bending strength and tensile strength are between polyethylene and polypropylene, and the Izod impact strength is only about 4kJ / m 2 , the material feels brittle and hard, and the skin affinity is extremely poor
Therefore, existing PBS material can't satisfy the requirement as disposable environmental protection mask cloth

Abstract

The invention discloses a biodegradable environment-friendly mask. The biodegradable environment-friendly mask comprises a mask body and ear straps arranged on the two sides of the mask body; the mask body comprises an outer layer, a filter layer and an inner layer from outside to inside; each of the outer layer and the inner layer is formed by use of a layer of PBS non-woven fabric; the filter layer is formed by use of at least one layer of bamboo fibers; each ear strap is formed by use of the PBS non-woven fabric. The environment-friendly mask can be completely biodegradable. The inner and outer layers of the mask and the PBS non-woven fabric and the bamboo fiber filter layer of the ear strap material all can be degradable, and the degradation rate of the non-woven fabric can be effectively controlled by use of the starch content, and furthermore, the cost can be reduced. In addition, the bamboo fibers and the PBS non-woven fabric used for the environment-friendly mask have the effects of bacterium inhibition, mite inhibition and deodorization, and the purposes of nature, environmental protection and health care of the mask can be achieved. As a result, the biodegradable environment-friendly mask has favorable application prospect in the field of the manufacture of green and environment-friendly articles for daily life.

Description

technical field [0001] The invention relates to a degradable environmental protection mask, which belongs to the field of daily necessities manufacturing. More specifically, it relates to an environment-friendly mask made of fully degradable natural environment-friendly bamboo fiber and polybutylene succinate (PBS) degradable materials. Background technique [0002] Masks are widely used in medical work and daily life, especially disposable masks. Ordinary disposable masks are generally made of non-woven fabrics. Non-woven fabrics are made from plastic raw materials similar to those used to make garbage bags. Thereby such disposable masks are used and discarded, just like plastic garbage bags, causing serious pollution to the environment. Therefore, the production and use of degradable environmental protection masks is very necessary, which can effectively eliminate the harm of disposable masks to the environment. [0003] At present, polylactic acid multilayer fiber mem...
