During this period, most nylon velcro stickers are grade a nylon, and domestic special nylon and imported special nylon are selected on the ejection hook. Therefore, the raw materials can be listed: polyester, blended, grade a nylon, domestic special nylon and imported special nylon (the latter two are mainly used for injection of hook back adhesive).

In the meantime, hot melt adhesives can be divided into general adhesives and strong adhesives (special varieties of hot melt adhesives can be used for special purposes such as temperature resistance and cold resistance). 3M is equivalent to strong adhesives in terms of viscosity, but it has the characteristics of high temperature resistance. There are many other 3M varieties, which are distinguished by types, and each type has different characteristics. Therefore, the general mainstream can be divided into general hot-melt adhesive, strong hot-melt adhesive and 3M adhesive.
