A face mask is a kind of hygiene product, which is generally worn on the mouth and nose to filter the air entering the mouth and nose to block harmful gases, odors, droplets, viruses and other substances. It is made of gauze or paper and other materials. Face Masks have a certain filtering effect on the air entering the lungs. Wearing masks has a very good effect when working in a polluted environment such as dust when respiratory infectious diseases are prevalent. Masks can be divided into air filter masks and air supply masks. The dust blocking efficiency of the mask is based on its blocking efficiency against fine dust, especially respiratory dust below 2.5 microns. Because dust of this particle size can directly enter the alveoli, it has the greatest impact on human health. The dust blocking principle of gauze masks is mechanical filtration, that is, when the dust collides with the gauze, some large particles of dust are blocked in the sand cloth through layers of barriers. For some fine dust, especially dust smaller than 2.5 microns, it will pass through the mesh of the gauze and enter the respiratory system. Dust masks are composed of activated carbon fiber felt pads or non-woven fabrics, and those respirable dust smaller than 2.5 microns are blocked in the process of passing through this filter material, which plays the role of filtering air.
A raincoat is a waterproof or water-resistant suit worn to protect the body from rain. In most fashion markets including America, France, and Asia, a raincoat refers to both the top and bottom including trousers. The term rain jacket is sometimes used to refer to raincoats that are waist length. A rain jacket may be combined with a pair of rain pants to make rain clothing. Rain clothing may also be in one piece, like a boilersuit. Modern raincoats are often constructed from waterproof fabrics that are breathable, such as Gore-Tex or Tyvek and coated nylons. These fabrics allow water vapour to pass through, allowing the garment to 'breathe' so that the sweat of the wearer can escape. The amount of pouring rain a raincoat can handle is sometimes measured in the unit millimetres, water gauge. For the production of raincoats, the common raincoat sewing technology on the market is to use overlock, which is less comfortable to wear and cannot completely prevent the infiltration of rainwater. Therefore, computer high-pressure PU heat-sealing treatment technology can be used to widen the heat-sealing belt, which can effectively prevent rainwater from infiltrating from the pinhole seam and enhance the rain-shielding effect of the raincoat.
Bedding, also known as bedclothes or bed linen, is the materials laid above the mattress of a bed for hygiene, warmth, protection of the mattress, and decorative effect. Bedding is the removable and washable portion of a human sleeping environment. Multiple sets of bedding for each bed are often washed in rotation and/or changed seasonally to improve sleep comfort at varying room temperatures. Most standardized measurements for bedding are rectangular, but there are also some square-shaped sizes, which allows the user to put on bedding without having to consider its lengthwise orientation (e.g. a 220 cm × 220 cm (87 in × 87 in) duvet). In American English, the word bedding generally does not include the mattress, bed frame, or bed base (such as box-spring), while in British English it does. In Australian and New Zealand English, bedding is often called manchester, especially in shops. Manchester was a center of the cotton industry in the late 18th and the 19th century, and into the 20th century, and so cotton goods (principally sheets and towels) were given the name 'Manchester goods', which later was simplified to 'manchester'.
Shoe covers are disposable slip-on garments that fit snugly over a variety of shoe style and sizes. They prevent potentially hazardous material (including organic and chemical particles) from coming in contact with the bottom of a person's shoes. According to its material classification: non-woven shoe covers, plastic shoe covers, cloth shoe covers, anti-static shoe covers, flannel shoe covers, rain-proof shoe covers, non-slip shoe covers.
In some industries with high frequency of glove replacement, it is usually recommended to use disposable gloves, which can not only avoid cross-infection, but also greatly save replacement costs, such as the medical industry, laboratory, food processing industry and other industries with high hygiene requirements. Disposable gloves are a type of gloves made of rubber sheets or films. According to the material, it is generally divided into plastic disposable gloves, latex disposable gloves, and nitrile disposable gloves; Among them, plastic film gloves are generally used in non-professional occasions. The advantage is that they are cheap, but because plastic disposable gloves are not elastic, their durability and suitability are relatively poor; Latex gloves are usually used in professional occasions, such as operating rooms, laboratories and other places that require high sanitary conditions. The advantage is that they have a certain elasticity and are more durable, but they are not resistant to animal grease corrosion, and are easily corroded by contact with animal grease. More importantly, according to statistics, 2%-17% of people will have varying degrees of allergy to latex. Nitrile gloves, in addition to having the characteristics of latex gloves, and improving the shortcomings of latex gloves, can first resist the corrosion of animal oils and fats, and will not cause allergies.
