List quality specifications for thermal fuses

Although thermal fuses have been around for more than 30 years, because they are only owned by a very small number of companies and their application scope is extremely narrow, there is no unified quality standard for thermal fuses. To put it bluntly, they are produced and supplied based on conscience. Those early suppliers were all good companies with very high self-discipline. They were responsible for their products to the end, formed good interactions with users, and made continuous improvements.

Summing up many years of experience in promoting hot-melt yarns, the quality of hot-melt yarns depends on: the stability of the melting point, the concave and convexity of the viscosity, the dyeing function and the tension of the yarn.

To achieve good melting point stability and small melting point error is a high-tech job. It is not difficult to achieve a low melting point, but it is not easy to achieve a small melting point error. If the melting point is too high, it will not melt at the set temperature, or will not melt, and will not achieve the intended bonding effect; if it is too low, it will easily cause “slurry leakage”, which will also fail to achieve the purpose.

Sticky bumps are the most easily overlooked in today’s use of thermal fuses. Everyone knows that thermal fuse is a kind of low melting point nylon filament, so painstaking efforts to achieve a low melting point is thermal fuse. As everyone knows, stickiness is the core value of thermal fuse. Few users pay attention to the sticky bumps, and the finished products look the same regardless. Stickiness requirements are often only raised by high-quality manufacturers.
The function of dyeing is especially important in the process of weaving first and then dyeing. If the dyeing performance is poor, it is very easy to cause color difference; some thermal fuse yarns are even almost impossible to dye.
The tension of the yarn is also a very important goal. Without a certain tension, the thermal fuse cannot be used.
Thermal fuse is a high-tech product. To produce high-quality thermal fuse, strong R&D skills are needed in the background. Especially in terms of later quality improvement, only companies with strong R&D capabilities can do it. .Zhejiang Ocean Star New Material Co., Ltd specializes in the production and sales of various thermal fuses (nylon thermal fuses, polyester thermal fuses, 3D shoe upper thermal fuses, etc.), with quality assurance and factory direct sales. Welcome everyone to inquire and order.
