Abstract

The invention discloses a preparation method of strawberry-shaped organic / inorganic crosslinked microsphere orientation filling enhanced chemical fibers. The preparation method includes the steps thatmonomer droplets are stabilized through pre-hydrolysed MPS and SiO2 nano-particles, and strawberry-shaped crosslinked composite microspheres are prepared through Pickering emulsion polymerization; and the microspheres and chemical slices are mixed, and after the processes such as melt spinning, drafting and winding, modified chemical fibers with the crosslinked composite microspheres for orientation filling enhancement are obtained. MPS pre-hydrolysed products for stabilizing the monomer droplets in Pickering emulsion are anchored on the surfaces of inorganic particles, and the interaction force between the inorganic particles and a polymer matrix is enhanced; and crosslinking structures in the microspheres provide deformation in the melt extrusion-stretching process for the composite microspheres, one-dimensional orientation micro-fiber structures are formed, the breaking strength of micro-fibers is enhanced, and radial mechanical defects are reduced.

Description

technical field

[0001] The invention relates to the technical field of reinforced chemical fibers, in particular to a preparation method of strawberry-shaped organic / inorganic crosslinked microspheres oriented filling reinforced chemical fibers. Background technique

[0002] With the continuous development of my country's economy and technology, and the increasing and diversifying social needs, higher requirements are put forward for the production and preparation of high-performance and specific chemical fibers. At present, although my country's chemical fiber industry is developing rapidly, the main products are still concentrated in the daily life application field, the product homogeneity is serious, and the price competition is fierce. Therefore, preparing high-strength and specific chemical fibers is an effective way to break through the price war, form core technologies, and increase market competitiveness.

[0003] At present, the methods for chemical fiber modifica...
