Abstract

The invention discloses a preparation method of grafted SiO2 particle cluster orientation reinforced polyester fiber. The method comprises the steps of carrying out vacuum drying on a polyethylene terephthalate (PET) chip and pomegranate-shaped polymethyl methacrylate (PMMA)/SiO2 graft composite microspheres; mixing the dried PET chip granules and the dried PMMA/SiO2 graft composite microsphere powder, feeding the mixture into a melt spinning machine, and carrying out melt extrusion; cooling, oiling, and carrying out spinning draft in a drawing machine to obtain the grafted SiO2 particle cluster orientation reinforced polyester fiber. According to the method, the grafted SiO2 particle clusters in the composite microspheres are sequentially arranged and regularly oriented along the axial direction of the fiber and the oriented SiO2 particles are connected front and back by carrying out melt blending, extrusion and drawing on the composite microspheres and polyester PET resin in the melt spinning machine and a spinning draft machine, so that a beam-shaped arrangement structure which takes the SiO2 particles as crosslinking points and PMMA graft chains as connecting lines can be built in PET fiber, and the polyester fiber finally has better mechanical strength.

Description

technical field [0001] The invention relates to the production field of reinforcing fibers, in particular to a grafted SiO 2 The preparation method of particle cluster orientation reinforced polyester fiber. Background technique [0002] It is an important proposition in fiber modification to orientally fill one-dimensional materials in micron-scale chemical fibers and endow them with new mechanical, electrical, and magnetic effects. High-strength and high-conductivity fibers such as carbon nanotubes and carbon fibers are the first one-dimensional materials to be selected, but these fibers are difficult to disperse in the melt regardless of whether they are modified or not. Adding a small amount will dramatically increase the viscosity of the composite system. so difficult to form. Therefore, Li Zhongming and Guo Shaoyun of Sichuan University (Chinese J Polym Sci, 2013, 31(2): 211-217; J Mater Sci, 2013, 48: 1214-1224) combined carbon nanotubes, carbon black, CaCO 3 The f...
