Като първото синтетично влакно в света, найлонът се използва широко в много полета, а неговите продукти имат строги технически изисквания .
In terms of basic performance, the melting point of nylon parts varies depending on the type, such as 220℃for nylon 6 and 260℃for nylon 66. However, the difference in melting point is not critical for some application scenarios, such as under common use temperature conditions. However, the resilience, fatigue resistance and thermal stability of nylon 6 are better than those of nylon 66. Найлоновите части също трябва да имат добра устойчивост на огъване, якост на опън, твърдост, както и устойчивост на износване, устойчивост на масло, здравина и други свойства .
Cleanability and anti-fouling properties are also important technical indicators. The cross-sectional shape and anti-fouling treatment of the fiber have a greater impact on these two properties, while the strength and hardness of the fiber itself have a smaller impact. In terms of color fastness, nylon itself is not easy to fade, but the dye in it fades under light.
In terms of wear resistance and dust resistance, nylon products of different materials have different performances. For example, experiments in places with extremely high traffic volume show that BASF Zeftron500 nylon 6 carpet is slightly better than DuPont Antron XL nylon 66 carpet in terms of color retention and pile wear resistance, and there is no difference in dust resistance between the two.
In the production of nylon soft bags, there are many technical links and requirements. The melting process has strict requirements on the melting temperature, time and other parameters of the raw materials to ensure fluidity and uniformity. The stretching process requires precise control of speed and tension to ensure film thickness and strength. The weaving composite process has high requirements on the density of the cloth and the bonding strength of the composite material. The printing process must make the pattern clear and the color bright, in line with relevant standards. At the same time, there are clear indicators for raw materials, nylon soft bag thickness, sealing performance, temperature resistance, chemical resistance and weather resistance, and a series of measures need to be taken to ensure the stability of the production process and product quality.
