Problems solved by technology

[0008] In view of the properties of POSS and graphene, the purpose of adding POSS and graphene to the fiber is to play the functions of POSS and graphene at the same time, but adding these two materials to the fiber separately will only play their own roles, and even hinder each other.
Moreover, the dispersion of graphene in the fiber polymer is also an important factor affecting the modification effect. If the dispersion is not good, it will lead to some performance degradation of the fiber.

Abstract

The invention relates to the field of polyester fiber modification, in particular to modified polyester fiber and a preparation method. Graphene oxide reacts with a vinyl-containing silane coupling agent, a vinyl modified graphene oxide is obtained and then subjected to a thiol-ene clock chemical reaction with octo(3-mercaptopropyl)POSS, then, the product reacts with allyl alcohol and then is reduced to obtain a hydroxyl modified POSS / graphene composite material, the material and epsilon-caprolactone are subjected to a loop opening reaction in a catalyst, and polyester / graphene / cage type polysilsesquioxane particles are obtained. The polyester / graphene / cage type polysilsesquioxane particles and polyester slices are subjected to fusion spinning to obtain modified polyester fiber. The obtained modified polyester fiber has the good electricity conductivity, heat conductivity, flame resistance and mechanical performance, and can be applied to spinning.

Description

technical field [0001] The invention relates to the field of modification of polyester fibers, in particular to a modified polyester fiber and a preparation method. Background technique [0002] Polyester fiber, commonly known as "polyester", is a synthetic fiber obtained by spinning polyester obtained by polycondensation of organic dibasic acid and organic dibasic alcohol, referred to as PET fiber. Its biggest advantage is that it has good wrinkle resistance and shape retention, high strength and elastic recovery ability, so it is widely used in textiles. [0003] As people's living standards are getting higher and higher, the requirements for clothing are also getting higher and higher. Not only are the clothes colorful, but they are also required to have some special properties, such as antistatic properties and anti-ultraviolet properties. Antistatic property is generally to add some antistatic agent or conductive agent in textile fiber, or use some hydrophilic finishin...
