Plant functional polyester filament and preparation method thereof

Abstract

The invention discloses a plant functional polyester filament and a preparation method thereof. The plant functional polyester filament comprises 0.1-1.5% of plant extract. The preparation method includes a step of plant functional polyester master batch preparation, and the step of plant functional polyester master batch preparation includes: slicing PET, heating to melt, adding an antioxidant and a dispersing agent, and stirring; then, adding a protecting agent and the plant extract, and mixing at a high speed; finally, adding a modifying agent, well mixing to obtain a mixture, and extrudingfor granulation. The plant functional polyester filament integrates high mechanical strength of polyester fibers and the anti-mite and antibacterial performance of the plant extract and has advantages of antibacterial and deodorizing effects, high wear resistance, high elasticity, comfort in hand feeling and less proneness to pilling and fouling.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a plant functional polyester filament and a preparation method thereof. Background technique [0002] As an important variety of synthetic fiber, polyester fiber accounts for more than 60% of the world's synthetic fiber output. It has the advantages of durability, good elasticity, not easy to deform, corrosion resistance, and insulation, especially its excellent wrinkle resistance and shape retention. Polyester fabric is washable, wear-resistant, non-ironing and wrinkle-resistant, so it is widely used in the fields of outerwear, home textiles, bags and tents. [0003] Polyester fibers containing plant extracts have broad application prospects because they have both the functional effects of plant extracts and the properties of polyester fibers in theory, but there are mainly the following problems in actual production: [0004] First, it is easy to change the properties of the ...

AI Technical Summary

Problems solved by technology

[0004] First, it is easy to change the properties of the original polyester fiber when mixed with other functional materials, such as affecting the elasticity and wear resistance of the polyester fiber. Second, the compatibility between various functional materials is poor. Using existing methods to combine plant extracts When directly added to molten PET, the plant extracts are easy to agglomerate, dispersed unevenly in the melt, and easily oxidized at high temperature; third, the existing plant functional polyester masterbatches have poor peelability during the spinning process. It is because the PET melt added with plant extracts is easy to produce an expansion zone after being extruded from the spinneret. The appearance of the expansion zone will affect the shape of the melt leaving the spinneret hole, and it is very easy to appear sticking plate phenomenon, which affects the spinning process. normal production;

[0005] In addition, polyester fiber, as a kind of artificial synthetic fiber, also has its own disadvantages. For example, the fabric made of polyester fiber will pill after using for a period of time, and it is easy to be charged with static electricity and dust, which affects the appearance and comfort. A good improvement method that affects the use of polyester fibers:

[0006] For example, the Chinese invention patent number CN201811438662.1, the invention name is a polyester fiber containing plant extracts, the fiber has good natural functionality, high dry heat shrinkage, breaking strength and elastic elongation, wear resistance It is also greatly improved, non-toxic, non-flammable, safe and environmentally friendly. This patent mainly solves the problem of the mechanical strength of the plant-functional polyester fiber, and cannot solve the shortcomings of the existing polyester fiber that is easy to pilling, fluffing, static electricity, and dust.
