Body protective equipment worn by defensive harmful factors injury to human health. Protection depends on the choice of cloth to resist hazards, persistence and practicality. Breathable fabric with moisture, breathable, warm, anti-fusibility, soft and non-deformation properties; gas-tight clothing (rubber, plastics and plastic coated fabrics such as leather) with impermeable, soft, anti-melting and anti-aging properties . Health and protection of the protective clothing requirements can be summarized into three points: the regulatory role of small body surface climate; safeguard the health and safety; able to adapt to the different activities of the body posture.
Clothing textiles materials, including the two major categories of natural fiber and chemical fiber textiles. Natural fibers such as cotton, linen, wool, silk (asbestos fiber fabric used in the past is no longer used). Chemical fibers are two types of man-made fibers and synthetic fibers. The man-made fibers natural brushed made of chemically treated cellulose or protein, such as viscose fiber; synthetic fiber is a byproduct of mineral production as raw material processing into yarn, such as polyester fibers (polyester). Of these fiber textile, knitting, woven into cloth and made into cloth. There are leather, artificial leather, rubber, plastic diaphragm products can also produce personal protective clothing. The artificial leather is coated on the base cloth scraping, made of extruded plastic, rubber layer, it has a good waterproof, acid, alkali, and electrical insulating properties. Airtight oak, plastic type products, wear easy to make the human body regenerative phenomenon caused by the illness. Therefore, for this type of costume design, to try to improve the permeability of clothing. Some protective clothing clothing dedicated a special treatment process. Retardant treated flame retardant cloth encounter fire lit, self-extinguishing, carbonized part can be cut off from the heat, in order to protect the body; wires or metallization layer silk blended fabric, has a shield, absorb microwaves and conductive properties, and clothing made of these fabrics can prevent the microwave oven body accumulation of static electricity; cloth made with rubber and plastic waterproof, acid, oil and insulation.
Wear insulated clothing is suitable in high temperature, strong radiant heat, metallurgy, furnace and other operating personnel, it can heat insulation, but also conducive to the evaporation of sweat. Nacelle using the good flame retardancy of the flame-retardant, heat insulation, reflective performance canvas, asbestos or glass fiber fabrics treated or aluminized fabric, in order to improve the reflection efficiency of the radiant heat, but such clothing permeability is poor. Synthetic fiber products, due to the heat-fusible nature and should not be used, while the the polyamide fabric should be taken only short-term wear. Design clothing, if only to defend against the front of the radiant heat can be made aprons, sleeves, after opening blouse to facilitate cooling. Around the operating environment of strong radiant heat, will have to wear protective clothing with the seal of the air-conditioning system. It consists of jacket, shirt, air conditioning, power system. Cover energy reflected radiant heat, gas-tight cloth made from the lining of the inner layer from the waist to the introduction of the total duct, all parts of the thin tube like dendritic branch distribution. In the hood, chest, back and limbs, has several side open there d TL thin tube the breeze administered by the hole sent to various parts of the body. Sent to the head of the air flow, so that blows the top of the head and neck, eye and not blowing. Purified air conditioning system is introduced from the outside air down to 15 ~ 18 ℃ and the capacity of not less than 80 1-100 L per minute. The exhaust gas is discharged from of cuffs, Kukou or exhaust valve. Hood installed - given the visibility of the gold-plated, aluminum glasses. Best fitted the headset and microphone, so that contact with the outside world. The feet wear insulated shoes easy to take off. The host portion of the air conditioning, power systems, with the operating point - given spacing, so there is the problem of interference with the operation of the air supply piping. Some foreign to this device is installed in a small trolley, the trolley ride operations workers, become the mobility seal protective suits. Some of the air conditioning, power system miniaturization, workers saddled job, but because of bulky, wear only suitable engaged in patrol light work. If only solve the problem of high-temperature radiant heat protection, anti-fang recoverable water cooling cap, vest, clothing, cooling, cooling vest can also use, in order to maintain the balance of body temperature. Wear clothing with such equipment, operating mostly operating in the narrow area, and at the same time setting industrial TV monitoring system and who installed traction urgent out of the system, in order to facilitate the timely detection of danger and rescue. This type of seal is also suitable protective clothing worn in workplaces with toxic gases, toxic dust and hypoxia staff, just do not have to cover with anti-radiation layer cloth making.
Winter clothes with low thermal conductivity of the cloth, which use more including the amount of air, fluffy, soft and lightweight material as a cold layer. Animal skin, hair, feathers, velvet, although ideal, but expensive. The performance of the the hollow synthetic fiber flakes close down. Bulkier batt making clothes the traditional wearing the sheepskin. Sensitive to cold parts of the design of the winter clothes structural style is to protect the back, abdomen, waist, upper arm and thigh. Costumes should not be too large for to reduce convection within the clothing should not be too narrow thin, so as not to affect the flexibility of the limbs, while impairing blood circulation and cause frostbite. Reasonable structure should be designed to be layered, segmented assembled clothing, and that selection of live lining, detachable sleeves, long pants, and connected to each other with a zipper and buckle by operating activities need to disassemble and assemble. Blouse remove the sleeves and a short-sleeve clothing or vests, trousers remove the lower half into shorts. The winter coat layers spaced not more than 10mm, so as not to affect the warmth.
