Abstract

The invention relates to the field of textile fibers, in particular to an aerogel filled pina composite fiber which has the advantages of high strength and toughness, excellent flexibility and elasticity and light weight, and a preparation process thereof. According to the invention, pina fiber powder is smashed to obtain ultrafine powder in an extremely fine state; the ultrafine powder is highlydispersed and stabilized by a casein solution, and in the step of forming fibers through jetting, casein acts as a binder, so as to form a good fiber structure; the fibers are immersed in an aerogel precursor to obtain precursor fibers, then are subjected to thermal treatment in a high temperature environment to obtain broken pina fibers; the broken pina fibers are connected by aerogel; and longitudinal cracks and holes and linear cavities in the pina fiber are filled with aerogel, so as to greatly improve the flexibility and elasticity of the pina fiber.

Description

technical field [0001] The invention relates to the field of textile fibers, in particular to an airgel-filled pineapple-based composite fiber with high strength and toughness, excellent flexibility, elasticity and light texture and a preparation process thereof. Background technique [0002] Pineapple hemp fiber, also known as pineapple hemp leaf fiber, is a fiber extracted from pineapple hemp leaves and belongs to leaf hemp fibers. Pineapple fiber is composed of many fiber bundles tightly combined, and each fiber bundle is composed of 10-20 single fiber cells. The surface of the fiber is rough, with longitudinal gaps and holes, horizontal branches, and no natural distortion. The monofilament cells are cylindrical, with pointed ends, smooth surface, and a linear lumen. Pineapple hemp fiber is white in appearance, soft and smooth, and feels like silk, so it is also called pineapple hemp silk. After deep processing, pineapple fiber has a white appearance, soft and smooth, ...
