< p > > outdoor a href= "http://m.pmae.cn/news/index_c.asp" > fabric > /a > is divided into two kinds, one is the outdoor sports fabric production clothing, this kind of material mainly takes mountaineering clothes, ski suit and assault clothing, the style is rough, the handle is stiff, the product performance request is very high, is suitable for the movement function type and the harsh environment uses, has the protection function to the human (the foreign big card asks this very strict, must let the international authoritative test organization as ITSSGS and so on test, the domestic brand does not have this detailed request).

< /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 fabrics. The functions include the following tests: shrinkage, joint slip, tensile strength, tear strength, pH, water resistance, water pressure, humidity, rain, light, water stains, sweat stains, friction, machine washout and other physical performance indicators.

< /p >

< p > these outdoor fabrics < a href= "http://m.pmae.cn/business/" > processing technology < /a > more complex than conventional fabrics, involving many 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 critical in the production process of textile fabrics.

< /p >

< p > 1, outdoor sports fabrics: generally made of nylon, polyester and other chemical fiber fabrics after processing: waterproof, calendering, dry wet coating, laminated film and other processes, with waterproof, moisture permeability, breathability, water pressure, UV resistant and other functional fabrics.

First of all, these functions should be started from the source. The source is the textile printing and dyeing mill.

< /p >

< p > 1, textile > /p >

< p > 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: American Standard Test AATCC-15 requirements: color change grade 4, stained color 3.

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

< p > notes: < a href= "http://m.pmae.cn/news/index_q.asp" > AATCC < /a > ASTM are all American test standards, JIS is Japanese test standard, ISO is European test standard, GB is Chinese standard, international standard is the largest in the United States, and all of them are foreign big name Columbia (Columbia).
