Embodiment 1

[0036] Cotton yarn card (20 s ×16 s , 128 × 60) in 4% water glass aqueous solution, two dipping and two rolling, pressure 0.3MPa, liquid carrying rate 70%, drying in a blast oven at 75°C, then washing and drying; use PG-350 of KUMAS company Spray 10% ammonium sulfate aqueous solution onto the fabric finished by the former with an electric sprayer, dry in a blast oven at 70°C, wash with water, and bake at 70°C for 3 minutes; the fabric has a bath ratio of 40:1 and a concentration of 0.050%. After soaking in the silver nitrate aqueous solution for 30 minutes, it was taken out, baked at 80°C for 3 minutes, washed with water, and finally the finished fabric was dried in an air blast oven at 80°C.

Embodiment 2

[0038] Cotton yarn card (20 s ×16 s , 128 × 60) in 4% water glass aqueous solution, two dipping and two rolling, pressure 0.4MPa, liquid carrying rate 60%, drying in 60 ℃ blast oven, then washing and drying; use PG-350 of KUMAS company Spray 10% ammonium sulfate aqueous solution onto the fabric finished by the former with an electric sprayer, dry it in an air blast oven at 80°C, wash it with water, and bake it at 80°C for 3 minutes; Dip and roll in the silver nitrate aqueous solution, the pressure is 0.3MPa, the liquid-carrying rate is 60%, then rolled up and stacked for 30 minutes, baked at 70°C for 3 minutes, washed with water, and finally dried the finished fabric in a 60°C blast oven Dry.

Abstract

The present invention discloses finishing method for nanometer antibiotic fabric. By means of sol-gel technology, silica gel is prepared on fabric with water glass of different modulus as precursor and ammonium salt as catalyst and used in padding fabric to introduce silver antibiotic and endow fabric with excellent lasting antibiotic performance. The fabric may have its 99 % over of colibacillus and Staphylococcus aureus killing rate maintained after being washed for 50 times. The finishing process has few influence on the hand feeling, whitenes and physical and mechanical performance of the fabric, uses no adhesive and dispersant, and has less pollution and low cost.

Description

technical field [0001] The invention relates to a finishing method of nano antibacterial fabrics, in particular to a finishing method of nano antibacterial fabrics without using any binder and dispersant. Background technique [0002] Antibacterial materials can be divided into three categories: organic, inorganic metal ion type and semiconductor photocatalytic type. Organic antibacterial materials have great application limitations due to problems such as poor heat resistance and insufficient durability; photocatalytic antibacterial materials are developing rapidly, but they need to further solve their problems such as ultraviolet light dependence and light utilization rate, and are still in the early stage of industrial application; Metal ion antibacterial materials have excellent heat resistance, spectrum antibacterial properties, safety, light resistance and chemical stability, and have a long antibacterial time, which is the mainstream product in the current antibacteri...
