What is the performance and test method of anti -rainstorm
With the popularity of outdoor sports, people put forward higher requirements for the functionality of outdoor materials, especially in extreme weather such as heavy rain. Therefore, high -performance outdoor materials have attracted more and more attention.
Rain rain generally refers to precipitation with a rainfall of more than 16mm per 1H, a continuous 12h rainfall of more than 30mm, or a continuous rainfall of more than 50 mm in a row. At present, the testing method of ritual rammer fabric mainly adopts Bondismen testing, and measures the ram and rain performance of the fabric through the surface dynamic water refusal performance of simulated fabrics in the rainstorm environment. The waterproof level of 10min in Bondis Gate test is above 3 or more waterproof and less than 3ml of water permeability. When the water absorption rate is below 25%, it is considered that the fabric has anti -rain and rain.
Second, the advantages of testing methods for ram and rainy performance
Compared with the static water -refusal test of ordinary splashing water, Bondis Gate test has the characteristics of larger water flow, faster speed, stronger impact, and more durable time.
Raintic rainfall fabrics usually use single cloth substrates and PTFE membranes for layer pressure composite to prepare. For single cloth substrates, the waterproof level of 10 minutes in Bondismen is required to be above 3 or more. It is below 10ml and 15%, respectively. The conventional waterproof and humidity fabric is difficult to meet the requirements. To this end, it is necessary to study the single cloth substrate suitable for riot rain fabrics.
Third, the influencing factors of the performance of the fabric and rainstorm performance
In addition to fabric substrates, the main factors affecting the resistance of the fabric and rainfall are the waterproofing of the fabric substrate, the waterproof and wet film, and the composite process. In recent years, researchers have carried out a lot of research on high waterproof and humid fabrics from the above -mentioned aspects. In response to the fabric substrate, the effects of the type of fabric or measuring, composite (coating or layer pressure) and the combination method of the waterproof and humidity performance of the fabric are shown that the waterproof waterproof capacity of waterproof and humid fabrics mainly depends on the fabric of the fabric. Waterproofing, anti -seepage, mainly depends on the anti -seepage of laminar pressure film or coating.
For waterproofing, because the C8 and C6 waterproof agents have potential carcinogenicity and environmental accumulation in the production and use of production and use. To this end, a fluorine -free waterproof agent with safety and environmental characteristics has become the direction of the development and promotion of researchers. Therefore, the effects of fluoride -free water -free watering process on cotton and polyester -cotton fabrics have the effect of refusing water performance. performance. After waterproofing, the waterproof level of the fabric can reach level 5 before washing, and the scores of 10 times 5A program after washing and drying can be kept above level 3. It has excellent dynamic dynamic water -refusal performance, but it still does not meet the requirements of rituals and rain. Therefore, there is a waterproofing of chemical fiber high -dense fabrics using fluoride waterproofing agents. The results show that after finishing through fluoride waterproof agent, it is finished (such as coating, fit, composite, etc.). Stable performance, strong stickers, good feel, and less white marks in hand.
In terms of waterproof and humidity membranes, the PTFE film and fabrics are mainly used in the market to achieve the high waterproof and humidity performance of the fabric. The effects of PTFE membrane thickness and type of fabric species on the waterproof and humidity properties of composite fabrics showed that the two PTFE membranes of different thickness were compounded with three fabrics, and the income composite fabrics had good waterproof and humidity performance.
Fourth, the research direction of the ram and rain performance of fabrics
However, with the improvement of people’s awareness of environmental protection, the preparation of traditional anti -raining fabric has been restricted. Therefore, it is necessary to develop green low -carbon anti -raining fabric preparation technology, such as fluoride waterproof organizing. Therefore, follow -up needs to combine the substrate structure of the fabric and the fluorine -free waterproofing process to explore the effects of various structural parameters of the fabric substrate on the performance of the ram and rain, and screen out the outdoor material substrate suitable for anti -raining. The performance of the waterproofing agent and fluorine -containing agent, select the best fluoride waterproofing agent with the best performance, and analyze its waterproofing process. By examining the quality concentration of waterproofing agent, the quality concentration of the cross -linking agent, and the liquid rate of liquid The influence is determined to determine the best fluorine -free waterproofing plan; explore the influence of the optimization of the structure and waterproof collation process of ritual rammer substrate and water resistance.
