Problems solved by technology

These large amounts of pollution and bacteria have greatly deteriorated the environment, greatly reduced the living environment of human beings, and affected human health.
People have also used various methods to optimize their living environment, such as ozone disinfection treatment, high-temperature steam disinfection, ultraviolet disinfection, spraying purifiers, etc. These methods are difficult to achieve the desired effect, and some have poor antibacterial and deodorizing effects. Some have a short antibacterial and deodorizing time, and some also form new pollution

Embodiment 1

[0019] The expanded photocatalyst polypropylene filament is made from the following raw materials in weight percentages: 0.5% of the photocatalyst, 1.3% of the coloring masterbatch, 98% of the polypropylene, and 0.2% of the spinning finish.

[0020] The production method of the above-mentioned bulked filament is as follows: firstly, the above-mentioned photocatalyst is sent into an oven at 200° C. and dried for 10 minutes so that the moisture content is lower than 0.1%. Then, the above-mentioned photocatalyst and polypropylene are mixed according to the above-mentioned ratio requirements, and then sent to a mixer for full mixing. Then the above-mentioned mixture is fed into a twin-screw extruder for extrusion granulation. The above-mentioned particles and colored masterbatch are fed into a single-screw extruder for melting and mixing after being proportioned according to the aforementioned proportioning requirements. The melt is extruded by the extruder and sent directly to the sp...

Embodiment 2

[0022] The photocatalyst polypropylene bulked filament is made from the following raw materials according to weight percentages, among which: photocatalyst 1.2%, coloring masterbatch 9.2%, polypropylene 89%, spinning oil 0.6%.

[0023] The production method of this photocatalyst polypropylene bulked filament is the same as in Example 1.

Abstract

The photocatalyst bulk polypropylene filament is prepared with photocatalyst 0.5-1.2 wt%, coloring agglomerate 1-10 wt%, polypropylene 89-98 wt%, and spinning oil preparation 0.2-0.6 wt%. Its production process includes mixing and pelletizing photocatalyst and polypropylene; adding coloring agglomerate and smelting; spinning and oiling. The photocatalyst bulk polypropylene filament is woven into fabric, which may be used in household, office, public field, traffic means, etc. to sterilize, eliminate bad smell, etc. so as to improve living condition.

Description

Technical field [0001] The invention relates to a new type of photocatalyst polypropylene expanded filament for sterilization, deodorization, disinfection and environmental purification, and a production method thereof. Background technique [0002] At present, there is a large amount of environmental pollution in rooms, public places, and vehicles. Such as aldehydes, phenols, alcohols and other harmful substances released by decorative materials. Carbon dioxide, carbon monoxide, and odor released from kitchens and bathrooms. Unpleasant smells, viruses and bacteria from pets, food, garbage, etc. Harmful substances emitted by air conditioners and refrigerators. Pollution caused by smoking, etc. These large amounts of pollution and bacteria have greatly deteriorated the environment, greatly reduced the living environment of human beings, and affected human health. People have also used various methods to optimize their living environment, such as ozone disinfection, high-temperatur...
