Abstract

The invention discloses a preparation method of melt-drip resistant inflaming retarding polyester fiber, comprising the following steps: mixing melt-drip resistant agent with a polyester slice, performing melt spanning, and processing and post-processing the mixture by alkaline solution and acid solution to form the melt-drip resistant inflaming retarding polyester fiber. The limited oxygen index of the melt-drip resistant inflaming retarding polyester fiber of the invention is 31-34, thereby melt dripping can not occur when the melt-drip resistant inflaming retarding polyester fiber burn, which can resist melt dripping effectively without releasing poisonous gas or smoke. Spinning melt-drip resistant inflaming retarding polyester fiber in accordance with routine melt spinning technology of the polyester fiber, the spanning is simple and easy to operate. The melt-drip resistant inflaming retarding polyester fiber can be directly and widely used as coatings, curtains, bedding articles, interior decoration and various special materials and the like, and has significant economic benefit and social benefit.

Description

technical field

[0001] The invention relates to a preparation method of polyester fiber, in particular to a preparation method of droplet-resistant and flame-retardant polyester fiber. Background technique

[0002] As the largest synthetic fiber, polyester fiber is used in a wide range of fields, such as clothing, curtains, bedding, interior decoration and various special materials. The limiting oxygen index of polyester fiber is only about 21. It is a flammable and flammable fiber, and there is a great hidden danger of fire when it is used.

[0003] More importantly, polyester fibers and various products made of polyester fibers will melt and drip when burned or at high temperature, which can easily cause burns and cause larger fires. The research on falling and flame retardancy has very important practical value.

[0004] At present, there are generally three types of flame retardant modification methods for polyester fibers:

[0005] (1) In the stage of transesterifica...
