Abstract

The invention relates to the field of masks, in particular to a preparation process of an enhanced fit mask. The preparation process comprises the following steps that 1, after a nose bridge strip isunwound, and then cut off, inputting and adhering to a strip-shaped non-woven fabric at intervals after cutting off are performed; 2, the strip-shaped non-woven fabric is sandwiched between an outer layer of non-woven fabric and a meltblown non-woven fabric to form a mask base material; 3, the mask base material is subjected to hot pressing to form a basic mask body shape; 4, the mask base material is subjected to secondary hot pressing; 5, the middle part of the mask base material is subjected to indentation; 6, an ear loop material is compounded on the mask base material; 7, cutting is formed to form a single mask body, 90-degree steering and folding are conducted; 8, hot pressing and cutting are performed; and 9, outputting is performed. According to the preparation process, an enhancedfit mask which has good air permeability and is not easy to slide off can be produced, and the technical problem that an existing folding type mask forms a sewing part through hot pressing at the nose bridge part can affect the ventilation performance is solved.

Description

technical field [0001] The invention relates to the field of face masks, in particular to a preparation process for a strengthened fit mask. Background technique [0002] At present, Chinese Patent No.: CN201420606372.4 discloses a foldable mask, which includes a mask body and ear buckles. The mask body includes two layers of polypropylene nonwoven fabric, one layer of melt blown nonwoven fabric and one layer of ordinary nonwoven fabric Two layers of polypropylene non-woven fabrics are respectively positioned at the outermost layer and the innermost layer of the mouth mask body, and the melt-blown non-woven fabric and the common non-woven fabric are respectively positioned between the two layers of polypropylene non-woven fabrics, and the common non-woven fabric and the innermost layer Layers of polypropylene non-woven contact. The folding mask has a good filtering effect, can filter 0.3 micron dust particles to more than 99%, and can shield liquids, bacteria, viruses and t...
