Description
Technical field
The invention belongs to textile material technical field, specially a kind of preparation method of antibacterial textile material.
Background technique
Traditional textile material is primarily referred to as fiber, and fiber is the basic unit of textile material.The source of fiber, composition,
Preparation, form, performance are extremely abundant and complicated.In simple terms, fiber is divided into natural fiber and chemical fibre two major classes.According to fibre
Natural fiber is divided into plant fiber, animal fiber and mineral fiber by the substance source attribute of dimension.By raw material, processing side
The difference of method and constituent, and regenerated fiber, synthetic fibers and inorfil three classes can be divided into.Chemical fibre is because its is excellent at present
Different service performance occupies the leading of market.But every kind of chemical fibre, while having advantage, there is also many deficiencies.
