Problems solved by technology

This method is poorly targeted and can only be used for polypropylene, and it is modified polypropylene, which has limitations in application
[0006] If the glass fiber and polyester are simply blended, the obtained ply yarn will be dispersed and cannot be condensed and plyed together, and the resulting non-cohesive ply yarn cannot fully reflect the duality of glass fiber and polyester during subsequent processing. superiority
Dispersion of ply filaments will occur in the resulting product, which will eventually reduce the strength and other physical properties of the product

Abstract

The invention relates to the field of chemical fiber manufacturing, in particular to a glass fiber reinforced polyester composite filament and a preparation method thereof. The composite filament is formed by mixing and compounding glass fiber and polyester. The fineness ratio of the glass fiber to the polyester is 1.8-3. The specific preparation method comprises the following steps: 1) pre-treating the glass fiber, 2) stranding, 3) false twisting, 4) sizing, 5) oiling and 6) winding molding to obtain a finished composite filament product. The glass fiber reinforced polyester composite filament with good performances can be obtained by the method.

Description

technical field [0001] The invention relates to the field of chemical fiber manufacturing, in particular to a glass fiber reinforced polyester composite filament and a preparation method thereof. Background technique [0002] Polyester fiber has been widely used in civilian fields because of its high strength, good impact resistance, heat resistance, corrosion resistance, and moth resistance. The fabrics made of polyester fibers are crisp and wrinkle-free. All kinds of textiles are currently the most widely used synthetic fibers. The emergence of one-step spinning and drawing (FDY) technology has further improved the strength of polyester filaments, reaching 5.6-8.0cN / dtex, which quickly made it widely used in industrial fields. However, due to the high investment in the equipment production line, and it is not suitable for small batch production, it has been greatly restricted. [0003] Glass fiber is an inorganic non-metallic material with excellent performance. It has v...
