Field sports are gradually becoming a popular trend in our country, and the search for field sports is slowly becoming a fashion. Therefore, the market share of field clothing in our country is getting higher and higher. Some students, white-collar workers and higher income groups have more and more functions and wearing comfort for clothing selection, so field functional clothing arises at the historic moment.

How to judge the quality and function of field clothing is mainly reflected in the function of textile fabrics. The function includes the following tests: shrinkage, seam slippage, elongation strength, tearing strength, PH value, water resistance, water pressure resistance, moisture permeability, rain, light, water stains, perspiration, conflict, machine washing and other physical performance indicators.

These field fabrics are more complicated than regular fabrics, touching more processing links, and have many functions such as waterproof, windproof, moisture permeability, water pressure resistance, warmth retention, perspiration, UV protection, etc. Therefore, it is very important to control the quality in the production process of textile fabrics.

Field Sports Fabric

Generally made of nylon, polyester and other chemical fiber fabrics after processing: waterproof, calendering, dry and wet coating, film composite and other processes, with waterproof, moisture permeability, breathable, water pressure resistance, UV resistance and other functional fabrics. Then these functions must first start 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 quality of the strength determines the quality of the fabric tearing. (Tear: After testing, the better the strength of the yarn, the better the wear resistance, and the better the effect of maintaining the human body in the field environment).

(2) Textile: Yarn in the process of textile machinery weaving to form gray cloth, adjust the machine, cut gray cloth crosspiece, broken warp and weft, holes, buckle road and other defects.

printing and dyeing

When dyeing in printing and dyeing factory, the color must be within the bearing range, and there must be no yin and yang colors. The quality of the cloth surface is qualified. The other is the important physical performance test:

(1) Hand feeling: It is required to be soft. The hand feeling of field sports fabrics is somewhat hard. At present, new products have been developed to improve the hand feeling, but field leisure fabrics are softer than field sports fabrics.

(2) Weft Inclination: The US Standard Test Specification AstmD3882 that the dyed cloth is required to be 3% of the useful width, while the plier cloth and printed cloth are required to be 2% of the useful width as qualified products. (If the weft inclination exceeds the scope of the American standard, it will easily lead to the deformation and distortion of the garment after washing, the asymmetric shape of the plier cloth printing cloth, and the unsightly appearance).

(3) Density: The American standard test AstmD3775 requires that the density in the longitude and latitude direction is within ± 3%.

(4) Weight: American standard test is ASTMD3776, and it is required to pass within 3%.

(5) PH value: The US standard test AATCC-81 requires 4.5-7.5 (the human body is weakly acidic, so the specified value is in the weakly acidic range, which is suitable for the human body. If it is alkaline, the skin is easily stimulated, dry and uncomfortable).

(6) Tearing strength: The US standard test ASTMD1424 is based on the specific requirements of different kinds of fabrics (kg KG, lb LB and Newton N are used for tearing to indicate the warp and weft test values of the cloth surface. The tearing quality affects the wear resistance of the clothing).

(7) Elongation strength: according to the specific requirements of different types of fabrics in the US standard test ASTMD5034 (kg KG, lb LB and Newton n are used to indicate the warp and weft test values of the cloth surface. The elongation strength affects the wear resistance of the clothing).

(8), seam slip: American standard test ASTMD434, according to the specific requirements of different types of fabrics (with MM to show the test value, the seam strength is good or bad, affect the slip of clothing seam).

(9) Shrinkage: The US standard test AATCC-135 requires 3% longitude and latitude (if the shrinkage exceeds 3%, it will affect the size deformation of the garment after several times of washing).

(10) Light fastness: US Standard Test AATCC-16E Requirements: Specific lamp tube shines level 4 for 20 hours and level 3 for 40 hours (mainly resistant to sunlight, generally wearing field clothing to prevent sunlight from changing color in skiing and mountaineering field sports. In case of danger, its dazzling clothing color is convenient for waiting for rescue).

(11) Colour fastness to conflict: American standard test AATCC-8 requirements: dry grinding level 4, wet grinding level 3. (This requires the degree of fading of clothing fabrics).

(12) Color fastness to water stains: American standard test AATCC-107 requirements: color change level 4, staining level 3. (This requirement is tested by cotton, nylon, polyester, wool, acrylic, vinegar and other cloth to see the grade of discoloration and staining).

(13), machine washing color fastness: American standard test AATCC-61-2A requirements: color change level 4, staining level 3. (This requirement is tested by cotton, nylon, polyester, wool, acrylic, vinegar and other cloth to see the grade of discoloration and staining).

(14) Color fastness to perspiration: American standard test AATCC-15 requirements: color change level 4, staining level 3. (This requirement is tested by cotton, nylon, polyester, wool, acrylic, vinegar and other cloth to see the grade of discoloration and staining).

White supplement: AATCC and ASTM are both American test standards, JIS is Japanese test standards, ISO is European test standards, GB is China's standards, and the international common standards are the most in the United States. Moreover, they are all foreign big-name columbia (Colombia) and THENORTHFACE(TNF north) as test standards. Many test indicators in China's standards have low requirements and are far from foreign standards.
