Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments.
Example one
This embodiment will be described in detail with reference to fig. 1 and 2. The gauze mask that glasses that this embodiment relates do not produce fog, including gauze mask body 1 and ear-hang 2, ear-hang 2 is fixed in gauze mask body 1's both sides to upper end middle part at the gauze mask body is fixed with nose holding strip 3. The periphery of the mask body 1 is fixedly connected in a sewing or ultrasonic welding mode, and the ear hook 2 and the mask body 1 are fixed by sewing or ultrasonic welding.
The mask body 1 comprises a surface layer 11, a moisture absorption layer 12, an adsorption layer 13 and a skin-contacting layer 14. The surface layer 11 generally requires a moisture-resistant function, and the spunbond nonwoven fabric and the through-air nonwoven fabric are used, and in this embodiment, the spunbond nonwoven fabric is selected, and the polylactic acid fiber is used as a specific raw material. The polylactic acid fiber is a novel green environment-friendly high polymer material which is obtained by using starch in some plants such as corn, wheat, cassava and the like as raw materials and using a bacterial fermentation or chemical synthesis method, the raw materials are sufficient and renewable, the production process is pollution-free, and the product is biodegradable. The polylactic acid spun-bonded non-woven fabric is used as a novel filament non-woven fabric, polylactic acid slices are used as raw materials, firstly, the slices are dried and then are subjected to a screw extruder, and the slices enter a melt pipeline and a spinning manifold after being extruded and melted and filtered by a melt filter; quantitatively feeding the melt into a spinning assembly for spinning through a metering pump in a spinning box body; the melt is sprayed out from spinneret holes in a form of thin flow, the thin flow is cooled by side air blowing at a certain temperature, after high-speed drafting is finished by a tubular drafting device, the fibers are uniformly laid on a web forming machine in an S-shaped track under the double actions of left and right swinging of a swinging piece and advancing of a web forming curtain to form a web, and finally the fiber is reinforced by hot rolling, needling or non-needling and other methods. Specifically, in this embodiment, the polylactic acid spunbonded nonwoven fabric used is a polylactic acid spunbonded hot-rolled fabric or a polylactic acid spunbonded spunlaced fabric, and the gram weight range is 20 to 50 grams per square meter.
The moisture absorption layer 12 is made of super absorbent fiber non-woven fabric, which is prepared by mixing super absorbent fiber (acrylic acid fiber SAF) and cotton fiber and needling, and has a quantitative of 40-50 g per square meter.
The absorption layer 13 is a melt-blown non-woven fabric or a polylactic acid nanofiber layer. The skin layer 14 is polylactic acid spunlace nonwoven fabric, specifically cross spunlace nonwoven fabric. In this embodiment, the adsorption layer 13 is selected as a polylactic acid nanofiber layer, and specifically, an electrostatic spinning device is used to deposit polylactic acid nanofibers on the surface of the skin layer 14. The polylactic acid fiber is accelerated and attenuated in an electrostatic field to form the polylactic acid nanofiber.
