Non-woven fabric mask cushion free of ironing

Technical Field

The utility model relates to a medical supplies especially relate to a non-woven fabrics gauze mask pad that non-ironing closed.

Background

China is a big country for manufacturing masks, the yield of the masks in 2019 exceeds 50 hundred million, and the masks account for about half of the global productivity, but the masks still are scarce materials when facing PM2.5 and epidemic situations of infectious diseases. To solve the problem of shortage of masks, means for increasing yield and energy rapidly are needed. However, the cost of one mask production line is hundreds of thousands, and the construction period is more than one month. Moreover, the existing mask production line is specially designed, the demand of the subsequent masks is reduced, a large number of production lines are idle, and huge assets are wasted.

The most widely used at present is a three-layer non-woven mask, wherein two outer layers are non-woven fabrics, and the middle layer is a filter sheet. The outer layer tends to accumulate a lot of dust and bacteria from the outside air, while the inner layer blocks exhaled bacteria and saliva. The non-woven fabric is not easy to clean and sterilize at high temperature, so that the non-woven fabric cannot be recycled, and the non-woven fabric is discarded and replaced by a new one after being used once. The mask is also provided with ear bands and nose clips, which are discarded.

In order to make the mask reusable, the internal sanitation of the mask needs to be kept except for avoiding the contamination of viruses on the surface of the mask, namely a disposable mask cushion can be added, and the mask cushion mainly has the effects of prolonging the service life of the mask and keeping the internal environment sanitary. Generally used for 2-4 hours and needs to be replaced. At present, several mask cushion products are available on the market, the production process is simplified compared with the mask, and the mask gap is partially solved. However, current mask cushions also have several problems: 1) the mask cushion is fixed with the outer-layer mask through the back adhesive, but if the inner side of the mask is wet due to long-time wearing of the mask, the mask cushion is not easy to stick. 2) The mask cushion is relatively hard and does not fit very well to the outer mask. 3) The current gauze mask pad production mode is similar with the gauze mask mode, and is still higher to the requirement of production facility, and the following table is combed current gauze mask pad and the specific of gauze mask:

	current mask cushion	Gauze mask
			Material	Three-layer non-woven fabric	Three-layer non-woven fabric
Nose clip	Fixed by using an external mask	Metal strip
			Ear belt	Fixed by using an external mask	Elastic thread
Pressing ironing	Ultrasonic wave	Ultrasonic wave

Therefore, the basic materials and pressing and ironing modes of the mask cushion and the mask in the prior art are the same, and only the nose clip and the ear belt are omitted. The existing mask cushion production equipment is only the reduction of mask equipment, and cannot be popularized on a large scale.
