Hi Vis Reflective Tape For Clothing – Test and analysis of the safety and durability of reflective materials
Hi Vis Reflective Tape For Clothing are the safety and protective clothing material used for special clothes, which are made up of a certain area of fluorescent fabrics and reflective materials. Fluorescent fabrics can absorb ultraviolet rays in the sunlight and emit visible light. Therefore, it can visually highlight the existence of wearers when daytime, early morning and evening and so on that the light is dim. How Does Reflective Material Work: The reflective material is also called retro reflection material, or retroreflective materials, the incident light according to the original road reflected light and reflection effects of light reflecting material incoming light at night or dark place is particularly prominent, which makes the motor vehicle driver, can be found far away or in the complex environment of the people, and respond.
The global related research results and practical experience show that the warning signs, clothing and accessories made of reflective materials are more than hundreds of times higher than other non-reflective materials under the illumination of lights, and have obvious effects on ensuring transportation and personal safety. In recent years, the rapid development of the transportation industry all over the world, the increasing amount of car ownership, security staff to solve the traffic and pedestrian traffic is very important, therefore the staff (traffic police, traffic wardens, and railway / highway maintenance staff) must wear a certain level of warning clothing. In addition, people in aviation, ground crew, firefighters, construction workers, rescue workers, and special industries such as environmental sanitation, port and petrochemical industry are wearing visual warning clothing, which can significantly improve the visibility of workers and ensure personal safety of workers.
How does reflective fabric work: However, people has been on the warning clothing retroreflective material knowledge, lack of understanding, although some workers put on the “warning suits”, but the “high visibility”, whether the driver can see at a distance, whether they play a security role, little is known about. It is impossible to know if the warning clothes that are dressed and washed for a period of time still have a warning effect. In order to make the high visual warning clothing play a more effective role in protecting the employees, it is necessary to study the initial retroreflective coefficient of different warning clothing reflective materials and the reflective properties after washing.
In this paper, through the comparative analysis of the reflection coefficient and the inverse washing on the performance of the initial WEALLIGHT reflective material and a domestic brand products of the same type, to help end users understand the “full range of visual effects of high requirements and daily washing of the reflective material properties, in order to fully protect the safety of users.

Test results and discussion of Hi Vis Reflective Tape For Clothing
A brief introduction to the retro reflection performance and principle
Hi Vis reflective tape for clothing materials only occupy a small part in high visibility warning clothing, but its use is the core factor of high visibility warning clothing. Therefore, the retroreflective performance of reflective materials is a very important index for testing product performance. Ideal is the light retroreflective along the incident axis all reflected back to the light source, but this reflective is not very useful, because do not have any of the reflective light is the eyes of the observer receives, actually reflective material is all incident light to the light cone form reflected back, the divergent light return way into observation the eyes. The angle between the incident light path and the reflection path is called the observation angle, most of the reflected light intensity are concentrated in the vicinity of the light cone axis, the farther away from the axis, the weaker light intensity, incident light path and the vertical angle between the reflective surface of the sample line become incident angle, reflective material inverse reflection principle as shown in Figure 1 shown.
The observation angle is different for the drivers of different vehicles. At the same time for the vehicle remote location, the path of reflected light path to the incident light only slightly, the viewing angle is very small, with the vehicle gradually approaching, the viewing angle and the incident angle is also increasing, in order to ensure high visibility at different distances, the light angle of divergence is big to the driver it is extremely important, the observation angle and incident angle of Figure 2, shown in figure 3.
Initial retro reflection coefficient test result and discussion
The reflective material retroreflective performance products as the assessment index, the initial inverse reflection coefficient of reflective materials must all comply with the relevant requirements of ISO20471-2013 “reflective vests – Test methods and requirements” or “ANSI/ISEA 107-2010” standard test reflective clothing supplies, this is the judgment of reflective material with continuous measure of high visibility of the most important. The retroreflective coefficient of WEALLIGHT products and a brand of the same type is tested in laboratory. The retroreflective coefficient test results are compared with the requirements in the standard, as shown in Figure 4.
The initial retro reflection coefficient test results are analyzed with the requirements in the standard, in which the higher or equal 100% indicates that the product meets the standard requirements. The test results show that the initial reverse reflection coefficient of WL-11010 reflective fabric and WL-11080 reflective fabric products of the WEALLIHT reflective material conforms to or is higher than the standard requirements. The retroreflective coefficient is the core index of reflective materials, which is directly related to the safety and protection performance of warning clothing, and the retroreflective coefficient meets the standard requirements, so that it can protect the wearer’s safety under different environmental conditions. Therefore, in order to ensure the high visibility performance of reflective materials, we need to carefully select the high visibility warning clothing reflective material, and the WEALLIGHT reflector can meet the standard requirements in all angles, which has a reliable warning performance.
Test results and Discussion on resistance to washing of Hi Vis Reflective Tape For Clothing
High visibility warning clothing in use will undergo a variety of climate change, but inevitably through washing care, reflective material with retro reflection coefficient of wearing time continue to drop, the water is one of the most important indexes influencing the durability of high visibility clothing, so the washing and nursing of high visibility warning clothing to use the most appropriate in the program, and most cannot use after washing times. After a certain number of washing for WEALLIGHT products and a brand of the same product, the typical retroreflective coefficient (incidence angle / angle of observation is 5 degrees /0.2 degrees) is tested in laboratory. The test results and comparison are shown in Figure 5.
After 30 times of claimed water washing, the typical reverse reflection coefficient of the WEALLIGHT reflective material WL-11010 home wash product is much higher than the standard. The number of samples after publicity after washing inverse reflection coefficient analysis of Mintab sample T- statistics, the results show that P=0, two kinds of products of retroreflection coefficient have obvious difference, WEALLIGHT reflective material WL-11010 reflective cloth products washing is better than the same type of a certain brand of -1 products.
After 100 washing, the typical reverse reflection coefficient of the WEALLIGHT reflective material WL-11080 industrial washing product is much higher than the standard. The number of samples after publicity after washing inverse reflection coefficient analysis of Mintab sample T- statistics, the results show that P=0, two kinds of products of retroreflection coefficient have obvious difference, a brand of -2 products launderability far lower than that of WEALLIGHT reflective material, reflective cloth WL-11080 products of the same type.

WEALLIGHT Hi Vis Reflective Tape For Clothing
With the increasing efforts of governments and the improvement of people’s safety consciousness, high visibility warning clothing has been widely applied in various industries, showing great market prospects. In order to ensure the safety of the protective effect of warning clothing, most countries have issued a unified national standard “mandatory use of high visibility warning clothing” occupation, and implementation of product certification of the market access system in accordance with the standard production and testing, the use of high visibility warning clothing has been standardized, the safety protection function will play a more important. However, due to the properties of fluorescent materials and reflective materials, clothing design and other factors have great influence on the warning function of high visibility warning clothing, poor quality fluorescent fabrics and reflective materials cannot protect the wearer’s safety effectively and effectively.
