Slip Resistance Test Secrets: Why Sole Friction & Tread Matter Most

 

Slips and falls have been identified as one of the main causes of accidents in the workplace, public places and at home. Why do people slip and fall? This is because the shoes have poor slip resistance properties, which leads to falls.

Characterization of slip resistance performance of footwear

Common sense tells us that the sliding between two objects is caused by the friction between them being smaller than the external driving force. If the friction between the shoes and the ground is larger than the tangential force generated when we walk, it will be enough to prevent the shoes from sliding, and slipping and falling will not happen or the probability of it happening is very small. Therefore, friction is the key factor in whether the shoes and the ground slide.
According to the friction coefficient formula:
μ=f/N, it is transformed into f=μ·N, (μ: friction coefficient; f: friction force; N: positive pressure)
It can be seen that: under the same pressure (such as shoe weight + human weight), that is, when N is constant, f is proportional to μ, that is, the larger μ is, the larger f is, which means that the friction between the sole material and the ground material is greater, and the more slip resistance; when a specific person wears the shoe, the pressure on the ground is basically constant, so the larger the friction coefficient is, the better the slip resistance performance is, so the sole friction coefficient becomes a parameter representing the slip resistance performance of the shoe.

Slip resistance tester

Slip resistance tester is based on the principle of the ratio of the horizontal force component to the vertical force component of the load, used to measure the maximum static coefficient of friction of footwear sole and heel against floor surfaces. This tester is portable and can be used on any kind of dry, wet or contaminated floor.

Fiber Fineness and Tenacity Test

Image
  Test methods explanation We have tested 5 fiber samples using two solutions to test fiber fineness and tenacity: Solution 1 and solution 2. Solution 1 We use YG002C measured the fiber diameter, and YG005S tested the break force and extension. The fiber density is converted to denier from diameter using the formula. Then use the break force divide the density to get the tenacity. Please move to TABLE 1 to view the test result. We have attached YG002C parameter sheet in Appendix 1 and YG005S parameter sheets in Appendix 2. Solution 2 We use ZK100F measured the fiber density, and YG005X tested the break force, extension, and tenacity. Please move to TABLE 2 to view the test result. We have attached ZK100F parameter sheet in Appendix 3 and YG005X parameter sheet in Appendix 4. A better solution for fiber density and tenacity testing  We also have a YG005XD AUTOMATIC FIBER TENSILE AND FINENESS TEST SYSTEM, which has integrated function of ZK100F and YG005X; it is equipped wi...

Selection of materials for jigger dyeing machine parts

Image
In the textile industry, the jigger dyeing machine is a key textile printing and dyeing equipment. The selection of its main manufacturing material has a vital impact on the performance, durability, and dyeing effect of the equipment. Stainless steel is one of the most commonly used materials in modern dye jigger manufacturing, especially 304 and 316L. Material selection for each component of the jigger dyeing machine The jigger dyeing machine is composed of a frame, an electric control cabinet, a vessel/top cover, a circulation system, a dye bath, a main roller, a guide roller, a tension frame, an additional tank, a debatching device, and other parts. More details about jigger dyeing machine in our company No contact with dye solution ​ For parts that are not in contact with the dye solution, the main consideration when choosing the manufacturing material is the use environment of the equipment. Generally speaking, the environment of the dyeing factory is harsh. We recommend using 304...

Requirements and Functions of Package Dyeing Machine

Image
For more than a century, the  package dyeing machine  has been invented, and it is extensively employed in the yarn-dyed and knitting industries because of its short process flow, quick adaptability to variety changes, high efficiency, low energy consumption, and reduced pollution. The functional scope of the machine has been enlarged in recent years with the development of allied technologies like as fiber materials, coloring materials, and electrical technology. It not only meets the dyeing process criteria, but it also considers variables such as efficiency, energy consumption, and environmental standards. This study expounds both theoretically and practically on these new functions in order to fully comprehend them. Basic requirements of package dyeing machine The essential needs for package dyeing machines are wide production application, high processing quality, economy, and environmental protection. Applicability Yarn may be spun from a variety of fibers, and there are ...
