Jackets, quick-drying T-shirts, sun protection clothing, etc. can be found everywhere in shopping malls and various e-commerce platforms. The prices range from tens to thousands of yuan. Functional textiles have the characteristics of “invisible, intangible, and only after use.” “Knowing” the characteristics, then how should consumers choose an outdoor textile that suits them?
The difference between outdoor functional textiles and ordinary textiles
There are many kinds of outdoor functional textiles, mainly including outdoor mountaineering clothing, jackets, ski clothing, mountaineering shoes, sun protection clothing, sleeping bags, tents, socks, gloves, etc. The main difference between outdoor functional clothing and ordinary home clothing is the increased functional requirements, that is, the clothing is required to have good heat dissipation and breathability, a certain degree of waterproofing and UV protection, and high windproof and warm performance requirements.
Currently, most of the outdoor textile clothing product standards on the market use the following product standards: GB/T 32614-2016 “Outdoor Sportswear Jackets”, GB/T 22853-2009 “Knitted Sportswear”, FZ/T 81007-2012 “Single, combined clothing” and so on. Take GB/T 32614-2016 “Outdoor Sportswear Jackets” as an example. In addition to formaldehyde, pH value, decomposable carcinogenic aromatic amine dyes, pilling, color fastness and other conventional indicators, the functional technical indicators are only Examine the moisture resistance and moisture permeability of the fabric surface. However, product standards such as GB/T 22853-2009 and FZ/T 81007-2012 do not mention and assess functional indicators. However, as functional products, textiles should have corresponding assessment requirements for their thermal insulation performance, breathability, antibacterial and hygienic performance, anti-UV performance, evaporation rate, water absorption, drip diffusion time, wicking height and other hygroscopic properties.
The quality of outdoor textile clothing varies widely
The Yinzhou Branch of the Technical Center of Ningbo Inspection and Quarantine Bureau has tested nearly 30 samples of outdoor textile clothing (including jackets, T-shirts, and pants) from multiple brands commonly seen on the market for waterproof performance, anti-UV performance, before washing and after 5 washes. The test of moisture absorption and quick-drying properties (including water absorption, dripping diffusion time, wicking height, evaporation rate, and moisture permeability) found that in addition to better UV resistance, products of different brands have great differences in several other inspection indicators.
Among them, the biggest difference is the waterproof performance and moisture absorption and quick drying performance. Products with better waterproof performance have a hydrostatic pressure resistance of more than 50 kPa, while poor products can only reach about 1 kPa; while moisture absorption and quick drying properties There is also a big difference in performance, especially in the diffusion time of dripping water. Some samples can be completely diffused on the fabric in 1 to 2 seconds, and those that meet the standard requirements are less than or equal to 3 seconds, while some samples cannot diffuse at all; after 5 washes Samples generally gave worse results than those before washing. Comprehensive comparison shows that there are great differences between different brands or different styles of the same brand. Some have good hygroscopicity but poor quick-drying properties.
How to choose outdoor functional textiles that suit you
At present, the market for outdoor functional textiles is in a confusing and confusing situation. When consumers buy outdoor functional textiles, it is recommended to touch, smell and look first. Take a jacket as an example: touch the fabric to see if it is wrinkled or degummed, whether the seams are tight, and whether the glued joints are smooth. Secondly, when you smell the smell, generally inferior products will have an unpleasant and uncomfortable odor when you open the package and gently shake it. Third, check the information to see if the content of the tag and durability label meets the requirements of GB 5296.4-2012. The details should include the name and address of the manufacturer, product name, product model or specification, fiber composition and content, maintenance methods, and implemented product standards. Safety categories, usage and storage precautions, and labels including special functional instructions, such as waterproof, UV-resistant, quick-drying, breathable, etc. For outdoor textile clothing, since you have decided to buy, you should buy good quality, especially for professional outdoor sports. It is recommended that consumers do not trust foreign trade goods, last-order goods and so-called high imitation products, and should try to choose regular channels to purchase.
In addition, the subsequent maintenance of outdoor functional textiles is also extremely important. Every wash will cause some damage to the clothes, so try to avoid frequent washing. If you choose machine washing when washing, you should choose a washing machine with professional outdoor clothing washing and drying programs, which can protect the skin with waterproof and breathable coating according to the material of outdoor clothing; or try to choose hand washing at normal temperature, focusing on brushing the dirty parts. Do not wring out clothes or iron them at high temperatures, as this will damage the coating and lead to a decline in functional indicators. It is advisable to dry them directly in the natural environment after washing.
