Abstract

The invention discloses a long-acting, washable and antibacterial fabric finishing method, which belongs to the field of textile engineering. The method provided by the invention comprises: (1) utilizing organic-inorganic composite lipids with antibacterial properties to prepare stable antibacterial siliceous bodies; (2) soaking the fabric in an antibacterial siliceous body solution after being treated with a plasma processor to carry out grafting reaction; (3) washing and drying the grafted fabric. After the surface grafting modification of the fabric is carried out by the present invention, the fastness and durability of the fabric adsorbed particles are improved, and the finished fabric belongs to the non-elution type antibacterial, has good biocompatibility, is eco-friendly, and is extremely washable. good.

Description

Technical field [0001] The present invention relates to the textile engineering field, particularly relates to a textile finishing process is a long-acting antimicrobial washing. Background technique [0002] Exist in nature mainly natural fibers, cotton, hemp, silk and animal hair. Wherein the molecular composition of cotton and hemp are mainly cellulose, silk and wool and molecular components of such major protein. Since natural fibers consisting essentially of polysaccharides and proteins, is therefore very easy to poor bacterial, fungal contamination, antimicrobial properties themselves. At present industrial production methods are commonly used antibacterial antibacterial agents need to be added, there are still some problems. For example: 1) using the extracted from plants and animals refined natural antibacterial antibacterial agent. Since the extract varied in nature, there is no general method to better antibacterial fabric, and poor fastness binding antibacterial agent,...
