Embodiment 1

[0034] A preparation method of a non-woven suit cover, comprising the following steps:

[0035] A. Slice preparation: put antibacterial agent, anti-ultraviolet agent and desiccant into melted DTY shape memory polyester slices, stir evenly, lower to room temperature, and obtain mixed slices;

[0036] B. Conveying of mixed slices: the mixed slices are transported by airflow to the raw material slice hopper above the extruder;

[0037] C. Extrusion: The mixed slices enter the twin-screw extruder by gravity, the mixed slices are heated and melted, and the excess polymer contained in the melt is sucked by vacuum, and finally mixed evenly and discharged under pressure;

[0038] D. Melt filter filtration: The melt out of the extruder first passes through the online filter to remove impurities, and is further mixed evenly by the static mixer, and then enters the spinning system;

[0039] E. Spinning: On the spinning machine of the spinning system, the melt first enters the spinning a...

Abstract

The invention discloses a preparation method of non-woven fabric suit covers. By adding antibacterial agent, anti-UV agent and desiccant into polyester slices, the prepared non-woven fabric suit covernot only has very good antibacterial, anti-ultraviolet and non-deformation performance, but it is also possible to ensure that suits in suit covers are kept dry for a long period of time to prevent mildew and odors in suits. Nano silver antibacterial agents can achieve long-lasting antibacterial effect. The adding of spinel powder not only has good anti-ultraviolet effect, but also is safe and environmentally friendly. The expanded vermiculite powder is used together with the carbon molecular sieve as a desiccant. Because of its low density, it is distributed on the surface of the polyester slice, which can effectively adsorb the moisture in the air, and can also adsorb the odor; the effect is good, and after washing and drying, the covers be used repeatedly.

Description

technical field [0001] The invention relates to the technical field of daily necessities, in particular to a preparation method of a non-woven suit cover. Background technique [0002] Non-woven fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. [0003] Non-woven fabrics have the characteristics of moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. For example, polypropylene (pp material) pellets are mostly used as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. [0004] Non-woven fabrics have the following advantages: [0005] 1. Lightweight: Polypropylene resin is used as the main raw material for production, and its speci...
