Abstract
The invention relates to the technical field of filaments, in particular to a quick-dry filament, a preparation method of the quick-dry filament and a toothbrush. The quick-dry filament is prepared from the following raw materials in parts by weight: PET (Polyethylene Terephthalate), PA (Polyamide), an additive, hydrophobic silicon dioxide, butyl stearate, polyoxosilane, an organic solvent, a plasticizer and an antibacterial agent, each part of compatilizer is composed of a PP grafted copolymer and PP according to the weight part ratio of 1: (5-10). The quick-dry fibril prepared from the raw materials is low in water absorption capacity and can be quickly dried in a short time, so that bacterium breeding of the fibril is reduced, the toothbrush bristles made of the fibril can be quickly dried after being used, and bacterium breeding on the toothbrush bristles is reduced.
Description
technical field [0001] The present application relates to the technical field of filaments, and more particularly, to a quick-drying filament, a preparation method thereof, and a toothbrush. Background technique [0002] The toothbrush is an oral cleaning tool that we use every day, and the bristles of the toothbrush mainly play a cleaning role. After brushing your teeth, toothbrushes are generally placed in the wash cup casually. If the moisture in the bristles cannot be removed in time, the bristles are in a damp state, and the bristles in the wet state are prone to self-breeding bacteria. At the same time, the toothbrush is usually air-dried, and the toothbrush is naturally It takes a long time to air dry, so when you brush your teeth again, the bacteria on the bristles will enter the mouth with the bristles, which will lead to oral diseases such as chronic tooth decay and periodontitis. SUMMARY OF THE INVENTION [0003] In order to improve the problem that the toothbr...
