There are underwear (bottom), bed and table linen. The main purpose of underwear: to protect your skin from pollution, irritation and mechanical damage outerwear and provide optimal microclimate of the body. Basic hygienic requirements underwear lingerie: low thermal conductivity, significant permeability, high hygroscopicity. Underwear should be easy and comfortable, elastic. In connection with the need for regular change of linen and its continuous washing linen materials should be resistant to detergents.
The choice of material and design (design) lingerie depend on the climate, season and destination. Easy linen is made from cotton fabrics (calico, crepe and others) and knitted fabrics, and synthetic materials. For production of warm clothes apply dense fabric and knitted fabric and knitted fabric with fleece of wool or synthetic fibres with low heat conductivity. Certain professional bodies (when working with radioactive substances, corrosive chemicals, and others) are given a special underwear. Hygienic requirements to special linen are determined by the nature of industrial hazards. Particularly high requirements to the quality underwear for members of polar expeditions, cosmonauts and other people who are in extreme conditions linen, produced from certain synthetic materials (acetate fiber and others), while wearing can have a significant electrostatic charge and is recommended as a "treatment".
The design and size lingerie depend on gender, age, human growth. Structural parts of the linen (gum, cuffs, etc., should not hamper movement, difficult breathing, and circulation. For persons with certain disabilities (lack of limbs), and for some patients (bed-patients) produce linen of special constructions.

Depending on certain conditions are determined by a time change of linen. For persons mild mental and physical labor, living in average climatic zone, this time is not more than 7 days. For people living in areas with a hot climate, and also engaged in heavy physical work (regardless of climatic conditions), the period-change of linen is reduced to 4 to 5 days or less. In order to reduce pollution of underwear and creation of optimal conditions of his socks are recommended to have separate clothes for sleep and wear in the daytime.

In public institutions widely used linen, disposable towels, napkins and other), made from conventional materials (going to the Laundry), and paper.
Laundry significantly changes its hygienic properties, there is a shrinkage of the fabric, decrease the permeability and water absorption, increased conductivity.
In the case of a bacterial or parasitic infection underwear should be subjected to special treatment (see Disinfection).

Linen child should be made taking into account the physiological features of a children's organism, imperfect thermoregulation and great mobility of children. Delicate and easily vulnerable skin in children of the first months of life requires lingerie soft hygroscopic fabric, without rough seams, with a soft drawstring, diapers, and the pins must be ironed. Baby clothes should be easy to miss the air and protect the body from cooling.
