热熔黏合聚酯的合成技术以及应用

Synthesis technology and application of hot melt bonding polyester

简述了热熔黏合聚酯的概况及性能特点,主要介绍了热熔黏合聚酯的合成技术以及产品应用领域。热熔黏合聚酯产品主要有三大类,即纤维状(如低熔点涤纶)、薄膜状(如热熔胶膜)、粉料或粒子状(如热熔胶)。热熔黏合聚酯的合成技术主要是低熔点聚对苯二甲酸乙二醇酯的合成、可生物降解热熔黏合聚酯的开发以及提高热熔胶的流动性、黏着性、功能性等。热熔黏合聚酯的应用领域主要是耐久性产业用纺织品、用即弃非织造布、医用胶粘剂及热黏合性薄膜。进一步降低成本、改善性能将加速热熔黏合聚酯产品产业化的进程。

The general situation and performance characteristics of hot melt bonding polyester were briefly described.The synthesis technology and application fields of hot melt bonding polyester were emphatically introduced.The hot melt bonding polyester products are primarily divided into three categories:fibrous low-melting point polyester fiber,film-like hot melt adhesive film and hot melt adhesive powder or particles.The synthesis technology of hot melt bonding polyester dominantly includes the synthesis of low-melting point polyethylene terephthalate,the development of biodegradable hot melt bonding polyester and the improvement of the fluidity,adhesiveness and functionality,etc..The application fields of hot melt bonding polyester mainly cover the durable industrial textiles,disposal non-woven fabrics,medical adhesives and hot melt adhesive film.The commercialization of hot melt bonding polyester products should be accelerated by the further production cost reduction and properties improvement.
