Análise do desempenho de combustão da fibra de poliéster com baixa fusão
Jan 08, 2020
In the field of textile materials, low-melting polyester fiber is receiving more and more attention due to its unique properties. This fiber not only has the strength and durability of traditional polyester fiber, but also performs well in the thermal bonding process due to its low melting point. However, its combustion performance, as an important indicator of safety, is also highly valued by the indústria .
The melting point of low-melting polyester fiber is usually between 110℃and 130℃, which is much lower than the 250℃to 260℃of ordinary polyester fiber. This feature enables it to soften quickly and form bonds when heated, and is widely used in clothing linings, non-woven fabrics and composite materials. However, the lower melting point also means that it is more likely to deform or Mesmo queima em um ambiente de alta temperatura, portanto, o estudo de seu desempenho de combustão é particularmente importante .
From the perspective of combustion characteristics, low-melting polyester fiber is a combustible material, but its burning speed and flame spread are greatly affected by fiber structure, additives and environmental factors. Experiments show that without flame retardant treatment, low-melting polyester fiber burns faster and may release a small amount of black smoke and odor. However, by adding flame retardants or blending with Outras fibras retardantes da chama, sua resistência ao incêndio pode ser significativamente melhorada para atender aos padrões de segurança mais rigorosos .
No cenário de aplicação, o desempenho da combustão da fibra de poliéster de baixa fusão afeta diretamente sua aplicabilidade em campos específicos ., por exemplo, em têxteis domésticos ou produtos infantis, geralmente é necessário tratamento retardador de chama para garantir a segurança; Enquanto em campos, como materiais de filtro industrial ou interiores automotivos, mais atenção pode ser dada à sua resistência ao calor e ao grau retardador de chamas .
In general, the combustion performance of low-melting polyester fiber is an important part of its comprehensive performance. With the improvement of environmental protection and safety standards, the industry will pay more attention to optimizing its flame retardant properties through technological innovation in the future to meet diversified market needs. For foreign trade companies, understanding the combustion characteristics of this fiber will help to accurately locate product application scenarios e aprimorar a competitividade do mercado .
