The material of adhesive Hook And Loop has a more significant effect when used in different industries. The clothing industry usually uses Hook And Loop with better materials because Hook And Loop comes into contact with the human body. If there is a problem with the Hook And Loop material, it can cause discomfort for personnel to use In some cases in the electronics industry, anti-static measures are required for products. If straps are used, there are generally no special requirements for the material But if we order a large quantity of adhesive Hook And Loop, we usually cannot judge whether the material used meets the requirements based on its appearance!

What methods do we have to determine the material of the adhesive Hook And Loop!

1. Correct identification method:

The methods of identification include tactile sensation, visual inspection, combustion, microscopy, dissolution, drug coloring, and infrared spectroscopy. In practical identification, multiple methods are often needed to comprehensively analyze and study the results.

The general identification steps are as follows:

A. Firstly, use the combustion method to distinguish between natural fibers and chemical fibers.

B. If it is natural fiber, use microscopic observation to identify various types of plant fibers and animal fibers. If it is a chemical fiber, distinguish it one by one based on the differences in melting point, specific gravity, refractive index, solubility, and other aspects of the fiber.

C. When identifying mixed fibers and blended yarns, it is generally possible to use a microscope to observe and confirm the presence of several types of fibers, and then use appropriate methods to identify them one by one.

D. For fibers that have been dyed or sorted, it is generally necessary to perform dyeing peeling or other appropriate pretreatment before ensuring reliable identification results.
