Preparation method for antibacterial polyester fibre with moisture absorption and perspiration elimination, and prepared fiber thereof

Abstract

The invention discloses a preparation method for an antibacterial polyester fibre with moisture absorption and perspiration elimination, and a prepared fiber thereof. The method comprises the steps ofselecting raw materials; grinding the raw materials to obtain polyester powder; mixing the polyester powder with plastic agents and forming agents, and adding mixtures to an internal mixer; obtainingmixtures A; mixing graphene oxide powder with modifiers, and heating and stirring the graphene oxide powder and the modifiers to obtain mixtures B; adding the mixtures A and the mixtures B to a granulator, and adding reinforcing agents and micropore agents; obtaining polyester master batch through melt extrusion; mixing the master batch with polyester slices, and adding mixtures to a spinning machine; making polyester into silk; drawing fibers into a shape with grooves; forming micropores at the interior and exterior of the fibers through a solvent dissolution slot; winding and coiling the formed silk, and airing the silk; and storing the silk for standby application after oiling. The invention further provides the fiber prepared with the method. According to the preparation method, graphene and other additives are added in the preparation process of the master batch, and the antibacterial property is improved; meanwhile, the fiber appearance is improved through a special spinneret hole process, and the functions of moisture absorption and perspiration elimination are improved.

Description

technical field [0001] The invention relates to a preparation method of graphene composite fiber and the prepared fiber, in particular to a preparation method of moisture absorption and perspiration antibacterial polyester fiber and the prepared fiber. Background technique [0002] In recent years, people have higher and higher requirements for the comfort, health, safety and environmental protection of clothing fabrics. With the increase of people's outdoor activities, the trend of mutual penetration and integration of casual wear and sportswear is also Increasingly favored by consumers, the fabrics of this type of clothing not only require good comfort, but also require that the clothing will not stick to the skin and produce a cold and damp feeling when sweating profusely occurs during activities. Therefore, new requirements for moisture absorption and perspiration are put forward for the fibers of the fabric. [0003] Natural fibers take cotton as an example. It has goo...
