Abstract

The invention discloses a composite fiber with a reticular structure and a preparation method thereof, and relates to the technical field of fibers. The preparation method comprises the following steps of grafting epoxidized soybean oil to PET under the action of a mixed catalyst, grafting styrene to an epoxidized soybean oil molecular chain under the action of an initiator to prepare modified PET, modifying PTT with modified maleic anhydride and polypropylene to prepare modified PTT, finally mixing the modified PET and the modified PTT, adding a catalyst A, a catalyst B and a polymerization inhibitor, and carrying out hot melt extrusion to obtain a spinning material, and spinning and drawing the spinning material to obtain the composite fiber with the reticular structure. The composite fiber prepared by the invention has an excellent net-shaped structure, good dyeing property and good mechanical property.

Description

technical field [0001] The invention relates to the technical field of textile fibers, in particular to a composite fiber with a network structure and a preparation method thereof. Background technique [0002] With the continuous development of science and technology, people have more and more requirements for textiles. Therefore, the fibers used in the preparation of fabrics need to have more and more properties. [0003] Composite fiber (English name composite fiber) is a kind of multi-component fiber, which is a term for man-made fiber varieties. There are two or more polymer fibers that are not mixed on the same fiber section. This fiber is called a composite fiber, which is a physically modified fiber developed in the 1960s. Bicomponent fibers that combine the properties of both polymers can be obtained using composite fiber manufacturing techniques. There are composite fibers such as side-by-side type, sheath-core type, sea-island type, etc., and the fiber cross-sec...
