Outdoor sports are gradually becoming a popular trend in China, and the pursuit of outdoor sports is slowly becoming a fashion. Therefore, outdoor clothing has an increasing share in the Chinese market. Some students, white-collar workers, and higher-income groups are increasingly interested in clothing choices. It is functional and comfortable to wear, so outdoor functional clothing emerged as the times require.
What is function?
Function means the beneficial role played by a thing or method. Functional clothing is to maximize the functions of clothing. Similarly, outdoor functional clothing is expensive due to its complicated processing technology. Well-known brands such as Columbia (Columbia) and THENORTHFACE (TNF North) are an outdoor clothing It’s worth thousands or thousands of dollars, why is it so expensive? Its brand culture has formed the value of the brand after decades of accumulation, interpretation and pursuit of quality.
Outdoor fabrics are divided into two types: one is clothing made of outdoor sports fabrics. This type of fabric is mainly mountaineering clothing, ski clothing, and jackets. It has a rough style and a stiff feel. It has very high product performance requirements and is suitable for sports functions. And used in harsh environments, it has a protective effect on people (foreign big brands have very strict requirements on this and must be tested by international authoritative testing agencies such as ITSSGS. Domestic brands do not have such detailed requirements).
The other type is clothing made of outdoor casual fabrics, which are defined as outdoor activities outside the home. This type of fabric is mainly casual and fashionable, and pays attention to fine workmanship, soft feel and comfortable wearing.
How to judge the quality and function of outdoor clothing is mainly reflected in the function of textile fabrics. The functions include the following tests: shrinkage, seam slippage, elongation strength, tearing strength, PH value, waterproofness, water pressure resistance, Physical performance indicators such as moisture permeability, rain, light, water stains, sweat stains, friction, machine washability, etc.
The processing technology of these outdoor fabrics is more complex than conventional fabrics, involving many processing links, and they have multiple functions such as waterproof, windproof, moisture permeable, water pressure resistance, warmth retention, sweat wicking, UV protection, etc. Therefore, it is very important to control the quality of textile fabrics during the production process. key.
outdoor sports fabrics
Generally made of nylon, polyester and other chemical fiber fabrics, they are processed through various processes such as waterproofing, calendering, dry and wet coating, film lamination, etc., and have various functional fabrics such as waterproof, moisture-permeable, breathable, water pressure-resistant, and UV-resistant. Then these functions must first be grasped from the source (the source in this article refers to the textile printing and dyeing factory).
textile
(1) Yarn: The quality of the yarn determines the quality of the fabric, and the strength determines the tearing quality of the fabric. (Tearing: Through testing, the stronger the yarn, the better the abrasion resistance, and the better it can protect the human body in the wild environment).
(2) Textile: During the process of weaving yarn into gray cloth by textile machinery, the machine must be adjusted to reduce defects such as horizontal rails, broken warp and weft, holes, and buckles in the gray cloth.
Printing and dyeing
When dyeing in a printing and dyeing factory, the color must be within the acceptable range, and there must be no yin and yang colors. The quality of the cloth surface must be qualified. In addition, important physical performance tests are mentioned:
(1) Hand feeling: softness is required, and outdoor sports fabrics have a somewhat hard feel. Currently, new products have been developed to improve the feel, but outdoor leisure fabrics are softer than outdoor sports fabrics.
(2) Weft and skew: The American standard test standard AstmD3882 requires 3% of the effective width for dyed fabrics, and 2% of the effective width for plaid and printed fabrics to be qualified products. (If the weft skew exceeds the American standard range, it will easily lead to deformation and distortion of the clothing after washing, and the plaid printed fabric will be asymmetrical and unsightly).
(3) Density: The American standard test AstmD3775 requires that the longitudinal and latitudinal density be qualified within ±3%.
(4) Gram weight: American standard test ASTM D3776, required to be qualified within ±3%.
(5) PH value: American standard test AATCC-81 requires 4.5-7.5 (the human body is weakly acidic, so the specified value is a weakly acidic range suitable for the human body. If it is alkaline, the skin will be easily irritated, dry and uncomfortable).
(6) Tear strength: American standard test ASTMD1424, according to the specific requirements of different types of fabrics (tear uses kilograms KG, pounds LB, Newton N to represent the longitude and weft test values of the cloth surface, the tearing quality will affect the durability of the clothing wear resistance).
(7) Tensile strength: American standard test ASTMD5034, according to the specific requirements of different types of fabrics (kg KG, pounds LB, Newton N are used to represent the longitude and weft test values of the cloth surface, the elongation strength is good or bad, which affects the wear resistance of the clothing durability).
(8) Seam slippage: American standard test ASTMD434, according to the specific requirements of different types of fabrics (MM is used to represent the test value, the strength of the seam affects the slippage of garment patchwork).
(9) Shrinkage: The American standard test AATCC-135 requires ±3% in the longitudinal and latitudinal directions (if the shrinkage exceeds 3%, it will affect the size deformation of the garment after being washed several times).
(10) Light fastness: American standard test AATCC-16E requirements: specific lamps are exposed to level 4 for 20 hours and level 3 for 40 hours (mainly resistance to sunlight, generally wearing outdoor clothing to prevent sunlight during skiing and mountaineering outdoor sports It is not easy to change color due to irradiation. If you are in danger, its eye-catching clothing color will make it easier to wait for rescue).
(11) Color fastness to rubbing: American standard test AATCC-8 requirements: dry grinding level 4, wet grinding level 3. (This requires the degree of fading of the clothing fabric).
(12) Color fastness to water stains: American standard test AATCC-107 requirements: discoloration level 4, staining level 3. (This requires testing on cotton, nylon, polyester, wool, acrylic, acetate, etc. cloth to see for discoloration and staining.(judgement level).
(13) Machine washing color fastness: American standard test AATCC-61-2A requirements: discoloration level 4, staining level 3. (This requires testing on cotton, nylon, polyester, wool, acrylic, acetate and other cloth pieces to see the discoloration and staining evaluation levels).
(14) Color fastness to perspiration: American standard test AATCC-15 requirements: discoloration level 4, staining level 3. (This requires testing on cotton, nylon, polyester, wool, acrylic, acetate and other cloth pieces to see the discoloration and staining evaluation levels).
Note: AATCC and ASTM are both American testing standards, JIS is Japanese testing standard, ISO is European testing standard, GB is Chinese standard, the most common international standards are American standards, and they are all foreign big-name Columbia (Colombia) and THENORTHFACE (TNF) North) and so on are used as test standards. Chinese standards have low setting requirements for many test indicators, which are far behind foreign standards.
