11 kinds of technical standards to be achieved by labor protection protective clothing

1, windproof waterproof and sweat-permeable clothing

Fabrics are made of PTFE membranes (PTFE membranes) that can be made into garments. The fabric can be impermeable to the slightest wind and can not penetrate a minimum of water droplets. It can discharge sweat from the body outside the clothes. The raincoat made of this material can be used as a coat when it is cold, and it can be used as a raincoat when it rains. It can be used to make: motorcycle clothing, jackets, raincoats, down jackets and other clothing, the main technical indicators are as follows:

Hydrostatic pressure ≥8000pa

Water vapor transmission ≥6000g/m2.D

2, far-infrared fiber clothing

The natural ceramic particles are mixed into a spinning solution such as polypropylene, and the filaments are pulled out. The silk contains ceramic particles and is blended with combed cotton fibers to make a knitted or woven fabric. It is worn closely and can reflect the far-infrared rays emitted from the human body back to the surface of the human body. It can penetrate the skin by 2mm or so to promote micro-vascularization. Blood flow makes people feel the temperature 3 °C ~ 5 °C higher than other clothing. It has a good effect on joint pain and skin diseases. The main technical indicators are as follows:

Far infrared reflectivity: ≥82%

3, dustproof clean clothing

The ribbed fabric with fine yarns and anti-static fiber has the advantages of permanent anti-static, breathable and comfortable, etc., together with dust-proof hats, socks and shoes. The main technical indicators are as follows:

Dust removal efficiency: ≥95%

Dust holding capacity: < 13.5g/m2

Top jacket charge: ≤ 0.5 μC/piece

4, antibacterial anti-mold anti-static clothing

Nano-scale silver ions are introduced into the fiber and blended with anti-static fiber and combed cotton fiber to make a woven or knitted fabric, which can achieve high efficiency and broad-spectrum bacteriostatic and anti-mold effect, permanent anti-static, anti-washing and good stability. The main technical indicators are as follows:

Antibacterial activity against Staphylococcus aureus: 99.6%, washing 50 times: 99.2%

Fabric charge density ≤5μC/m2

5, anti-electromagnetic radiation clothing

Made of stainless steel fiber and polyester-cotton blend fabric or nylon silver plated/nickel plated/copper plated/tin plated metalized fabric. The main technical indicators are as follows:

Shielding efficiency: 30db ~ 85db

Shielding range: 30MHz to 10GHz

6, perspiration chemical protective clothing

The protective clothing made of PTFE membrane paste cloth and made of activated carbon microparticle cloth can be used for a long period of time. It has the functions of anti-virus, waterproof, windproof, and perspiration. The main technical indicators are as follows (For details, please refer to the website of the company "Firefighters anti-virus fire protective clothing"):

Fabrics with hydrostatic pressure ≥8000pa

The moisture permeability of the fabric is ≥6000g/m2.d

Anti-virus function: 6 hours for mustard gas "liquid-gas" antivirus

Mustard gas "liquid-liquid" pressure resistance> 147000pa

Specific surface area of ​​activated carbon on cloth > 600M2/g

The content of activated carbon on the cloth: 40g/m2～100g/m

7, anti-acid clothing

Nomex® Workwear has a permanent anti-acid and alkali function but at a high price.

The tussah silk weaving cloth, in the face of acid or alkali, tussah silk expands, close the gap between tussah silk, can completely block the acid or alkali, can not go inside the clothing, to prevent acid and alkali purposes. The garment is comfortable, beautiful, breathable and wrinkle-resistant, easy to wash and dry, and inexpensive.

8, high voltage live working clothing

It is made of stainless steel fiber and flame-retardant fiber (Nomex®), which can be used for electrification of 10KV-500KV power transformers. It is equipped with gloves, hats, socks and shoes. Its performance is in line with GB6568.1-2000. Standards, main technical indicators are as follows:

Shielding efficiency: ≥30db～60db

Fabric resistance: ≤0.8Ω

Limiting oxygen index: Loi > 28

Moisture permeability: ≥8000g/m2.D

9, anti-UV antibacterial anti-mildew clothing

Nano-technology is used to introduce ultraviolet segregation factor and bacteriostatic and anti-mould precursor into ultra-fine denier fibers. The woven or knitted fabrics blended with combed cotton fibers can block and absorb ultraviolet rays, and have high-efficiency and broad-spectrum antibacterial and antifungal effects. . The hydrophilic properties of the ultra-fine fibers remove sweat in a timely manner, keeping the skin dry. The main technical indicators are as follows:

Block and absorb UV> 92% to 99%

Staphylococcus aureus inhibition rate> 99.5%

Moisture removal capacity: > 8000g/m2.D

10, anti-static clothing

Using stainless steel fiber, sub-conducting fiber, anti-static synthetic fiber and polyester-cotton blended or mixed weaving fabric, can automatically corona discharge or leakage discharge, can eliminate clothes and human body, at the same time for anti-static hats, socks, shoes. Its performance indicators meet the GB12014-89 standard:
