How To Judge The Quality And Function Of Outdoor Clothing

< p > outdoor sports have been spread to China from abroad for over ten years. It has become an increasingly popular trend. Outdoor clothing occupies a higher share in China. Some white-collar and higher income groups have more and more functional and comfortable clothing choices. Therefore, < a href= "http://www.91se91.com/news/index_s.asp" > outdoor functional clothing < /a > came into being.

< /p >

< p > what is function? It means the beneficial effect of things or methods. The functional clothing is to maximize the function of clothing. The same outdoor functional clothing causes its price to be expensive because of its complex processing technology. Famous brands such as Columbia (Columbia) and THENORTHFACE (TNF North) are worth thousands of yuan or thousands of dollars. Why is it so expensive? Its brand culture has been formed after decades of accumulation and interpretation and quality pursuit, forming the brand value; as a professional outdoor brand fabric technician in the past four years, I have analyzed the quality and functional indicators of outdoor sportswear fabrics (except for clothing).

< /p >

< p > outdoor fabrics are divided into two categories, one is made of outdoor sports fabrics. The fabrics are mainly made of mountaineering clothes, ski suits and assault clothing. The style is rough and the handle is strong, and the performance requirements of the products are very high. They are suitable for use in sports function and harsh environment, and play a protective role for people. (foreign brands are very strict about this requirement. The international authoritative testing organizations such as ITSSGS must be tested, and domestic brands do not have such detailed requirements).

< /p >

< p > the other is clothing made of outdoor casual fabrics. The definition is that it is outdoor activities outside the door of the home. The fabric is mainly casual fashion, exquisite workmanship, soft touch and comfortable clothing.

< /p >

< p > how to judge the quality and function of outdoor clothing, its meaning is mainly embodied in the function of textile fabric. The functions include the following tests: shrinkage, joint slip, tensile strength, tear strength, pH value, water resistance, water pressure, humidity, rain, light, water stains, sweat stains, friction, machine washout and so on. < a href= "http://www.91se91.com/business/ >" performance index < /a >.

< /p >

< p > these outdoor fabrics are more complex than conventional fabrics. They involve a lot of processing links, and have many functions such as waterproof, wind protection, moisture permeability, water pressure resistance, warmth retention, sweat and ultraviolet protection. Therefore, quality control is very important in the production process of textile fabrics.

< /p >

< p > 1, yarn quality and strength: the quality of yarn determines the quality of fabric and determines the quality of fabric tear.

(tearing: the strength of the test is better, wear resistance and durability are better, and it can protect the human body in the wild environment.)

< /p >

< p > 2, quality of printing and dyeing plant: dyeing and dyeing must be within the acceptable scope of the printing and dyeing plant, and the quality of the cloth is qualified. In addition, the important physical performance test is: < /p >

< p > (1), soft feel, but outdoor leisure requirements are softer than outdoor fabrics.

< /p >

< p > (2), latitude oblique: American Standard Test Standard AstmD3882 dyeing cloth requirement is 3% of effective width, the grid and printing cloth request is effective width 2% is qualified product.

(if the skew deviation exceeds the American standard range, it will easily lead to distortion and distortion of dyed fabric washed after washing.

< /p >

< p > (3), pH value: the American Standard Test AATCC-81 requires 4.5-7.5 (the body is weak and acidic, so the prescribed value is suitable for the human body in the weak acidic range. If it is alkaline, the skin is irritated and dry and uncomfortable.)

< /p >

< p > (4), tear strength: American Standard Test AstmD1424 according to the specific requirements of different varieties of fabrics (tear quality, affect the wear and durability of clothing).

< /p >

< p > (5), tensile strength: American Standard Test ASTMD5034, according to the specific requirements of different varieties of fabrics (tensile strength is good or bad, affects the wear-resistance and wearability of clothing).

< /p >

< p > (6), joint slip: American Standard Test ASTMD434, according to the specific requirements of different varieties of fabrics (strength of joints, affect the slippage of garment joints).

< /p >

< p > (7), shrinkage rate: the American Standard Test AATCC-135 requires 3% (if the shrinkage rate exceeds 3%, it will affect the size of the clothes washed for several times).

< /p >

< p > (8), light fastness: American Standard Test AATCC-16E requirements: specific lamp for 20 hours irradiation 4 level, 40 hours irradiation level 3 (this requirement is relatively high (white and sensitive color and nylon elastic cloth) because of its own defects and technical difficulties, it is difficult to achieve this index; mainly is sunlight resistance, generally wear outdoor clothing in skiing, mountaineering outdoor sports to prevent sunlight exposure is not easy to change color, if distress situation, its waking color, waiting for rescue convenience.

< /p >

< p > (9), rubbing color fastness: American Standard Test AATCC-8 requirements: dry grinding grade 4, wet grinding 3 stage.

(this requires fabric fading).

< /p >

< p > (10), water stain fastness: American Standard Test AATCC-107 requirements: color change grade 4, stained color 3.

(requirement of cotton, nylon, polyester, wool, acrylic, vinegar and so on).

< /p >

< p > (11), machine wash color fastness: American Standard Test AATCC-61-2A requirements: color change 4 grade, stained color 3.

(requirement of cotton, nylon, polyester, wool, acrylic, vinegar and so on).

< /p >

< p > (12), color fastness to perspiration: < a href= "http://www.91se91.com/news/index_q.asp" > American Standard Test AATCC-15 < /a > requirement: discoloration grade 4, stained with color 3.

(requirement of cotton, nylon, polyester, wool, acrylic, vinegar and so on).
