China already has more than ten years, already gradually into a popular trend, the outdoor clothing market share in China is higher and higher, some white-collar and high income groups of clothing choice is more and more with a functional and wearing comfort so the function of outdoor clothing was born.
Outdoor fabrics are divided into two kinds, one is outdoor sports fabric production of clothing, such fabrics mainly to mountaineering suits, ski suits, Jackets mainly style, rough style, feel stiff, the product performance requirements are very high, suitable for sports functional And the use of harsh environments, people have a protective effect (foreign big on this request is very strict, we must let the international authority of test institutions such as ITSSGS test, domestic brands do not have this detailed requirements).
Another is the outdoor leisure fabric production of clothing, the definition is out of the house is the outdoor activities, such fabrics to leisure fashion-based, pay attention to fine workmanship, soft, comfortable to wear.
How to judge the quality and function of outdoor clothing, its meaning is mainly reflected in the textile fabric function, the function includes the following tests: shrinkage, seam slip, elongation strength, tear strength, PH value, water resistance, Humidity, rain, light, water stains, perspiration, friction, machine wash, and so on physical performance indicators.
These outdoor fabric processing technology than the conventional fabric complex, involving processing and more links, and has a waterproof, windproof, moisture, water pressure, warm, perspiration, anti-ultraviolet and other functions, so in the textile fabric production process control quality is very The essential.
First, outdoor sports fabrics: generally by the nylon, polyester and other chemical fiber fabric after processing: waterproof, calendering, dry and wet coating, film composite and other technology, with waterproof, moisture, breathable, water pressure, anti-ultraviolet Various functional fabrics. Then these features should first start from the source, the source is the textile printing and dyeing factory.
Yarn quality and strength: the quality of the yarn determines the quality of the fabric, the strength of the fabric to determine the quality of tear. (Tear: better by testing the better, better wear resistance, better protection of the human body in the wild environment).
2, the quality of printing and dyeing factory: dyeing and printing plant color dyeing must be within the scope of acceptance, the fabric quality, the other is to talk about important physical performance test:
(1), feel soft, but outdoor leisure requirements than outdoor sports fabric to be softer.
(2), weft oblique: American standard test standard AstmD3882 dyeing cloth requirements are effective width of 3%, lattice cloth and printing cloth requirements is effective width of 2% for qualified products. (Weft oblique if the scope of the US standard is easy to lead to dyeing cloth washed after washing distortion, lattice cloth printed cloth is not allowed to shape, not beautiful).
(3), PH: American standard test AATCC-81 requires 4.5-7.5 (weak body acidic, so the provisions of the weak acid range for the human body, if the alkaline, the skin by the stimulation of dry and uncomfortable).
4), tear strength: American standard test AstmD1424 according to the specific requirements of different varieties of fabric (tearing good or bad, affecting the wear and tear of clothing).
(5), elongation strength: American standard test ASTMD5034, according to the specific requirements of different varieties of fabric (elongation strength is good or bad, affecting the wear and tear of clothing).
(6), seam slip: American standard test ASTMD434, according to the specific requirements of different varieties of fabric (seam strength is good or bad, affecting the clothing patchwork slip).
(7), shrinkage: American standard test AATCC-135 requires 3% (shrinkage if more than 3%, affecting the cost of washing clothes to wash several times the size).
(8), light fastness: American standard test AATCC-16E requirements: a specific lamp 20 hours irradiation 4, 40 hours irradiation 3 (this requirement is relatively high, white and sensitive color and nylon elastic cloth due to their own defects and technology It is difficult to achieve this indicator; mainly resistant to sunlight, the general wear outdoor clothing in skiing, mountaineering outdoor sports to prevent the sun is not easy to change color, in case of danger, the eye-catching clothing color, waiting for rescue convenience).
(9), friction color fastness: American standard test AATCC-8 requirements: dry grinding 4, wet grinding 3. (This requires the degree of fading of the fabric).
(10), water fastness: American standard test AATCC-107 requirements: color 4, stained 3. (This requirement through the cotton, nylon, polyester, wool, acrylic, vinegar and other tests to see the color, stain rating).
(11), machine washing color fastness: American standard test AATCC-61-2A requirements: color 4, stained 3. (This requirement through the cotton, nylon, polyester, wool, acrylic, vinegar and other tests to see the color, stain rating).
(12), perspiration color fastness: American standard test AATCC-15 requirements: color 4, stained 3. (This requirement through the cotton, nylon, polyester, wool, acrylic, vinegar and other tests to see the color, stain rating).
