Embodiment 1

[0024] Choose 150g / m 2 The 100% waste spinning polyester fiber sewing non-woven fabric is used as the base material, and the silver carbonate nanoparticle chelate solution 100kg containing silver 100ppm (by mass) is selected as the antibacterial agent A component, and the 50g Dioctadecyl dimethyl ammonium chloride wetting, gradually add water to dissolve, until completely dissolved, add water to 400kg, as the antibacterial agent B component, mix the antibacterial agents of the two components to obtain an antibacterial finishing solution. The stitch-bonded nonwoven material with high efficiency, durability and antibacterial properties can be obtained after finishing the process as follows.

[0025] Unwinding - Saturated impregnation rolling to 150% liquid loading rate - Drying cylinder pre-drying to below 50% liquid loading rate - Drying in tenter oven to shape - Trimming - Rolling

Embodiment 2

[0027] Use chemically bonded 180g / m 2 The 100% polyester waste spinning fiber needle-punched non-woven fabric is base material, selects silver carbonate nanoparticle chelate solution 200kg containing silver 100ppm (by mass) as antimicrobial agent A component, with 50g dehydrated alcohol to 50g Dioctadecyl dimethyl ammonium chloride wetting, gradually add water to dissolve, add water to 300kg after complete dissolution, as the antibacterial agent B component, mix the antibacterial agents of the two components to obtain an antibacterial finishing solution. The chemically bonded needle-punched nonwoven material with high efficiency, durability and antibacterial properties can be obtained after the following finishing process.

[0028] Unwinding—spraying on one side to 70% liquid carrying rate—pre-drying to less than 40% liquid carrying rate—spraying on the reverse side to 70% liquid carrying rate—drying and shaping in a stenter oven—cutting - in rolls

Embodiment 3

[0030] Choose 70g / m 2 The polyester spun-bonded non-woven fabric is the base material, and 100 kg of silver carbonate nanoparticle chelate solution containing silver 100 ppm (by mass) is selected as the antibacterial agent A component, and 50 g of dioctadecane is mixed with 50 g of dehydrated alcohol. Dimethyl ammonium chloride wetting, gradually add water to dissolve, until completely dissolved, add water to 300kg, as antibacterial agent B component, the antibacterial agent of two components are mixed to prepare antibacterial finishing liquid. The polyester spunbonded nonwoven material with high efficiency, durability and antibacterial properties can be obtained after finishing the process as follows.

[0031] Unwinding—two dipping and two rolling to 100% liquid carrying rate—pre-drying in dryer to less than 40% liquid carrying rate—drying in stenter oven to shape—trimming—rolling

Abstract

The invention provides a method for making a durable compound antibiosis nonwoven cloth material. By performing an efficient combination of insoluble silver particle pincer system which has a non dissoluble type high efficient antibiosis function with dissoluble type chlorine system quaternary ammonium salt, an antimicrobial solution with a certain concentration is made, by performing immersing and rolling finishing on the chemical fiber non woven cloth with the antimicrobial, a non woven cloth which combines active antibiosis and passive antibiosis functions is made, the non dissoluble silver pincer complex is a nanometer particle pincer complex of silver carbonate or silver bromide; the quaternary ammonium salt is a CTMAC or a double stearyl DHTDMAC, which has a good surface treating and antibiosis performance; as for the mixture ratio of the two, the former is 10 to 60 percent, the latter is 90 to 40 percent, and as for the optimal mixture ratio, the former is 25 percent and the latter is 75 percent. The after finishing is adding the assembled antimicrobial onto the molded non woven cloth coiled material by immersing and sprinkling, and baking and sizing the material, without any other surface pre-treating process.

Description

Technical field: [0001] The invention belongs to the textile industry and relates to a method for manufacturing a durable composite antibacterial nonwoven material. Background technique: [0002] Since the late 1990s, nonwoven materials have been gradually developed in China. After nearly 20 years of continuous research and improvement, at present, the development and application of domestic nonwoven products have gradually penetrated into various fields. The functional requirements of young materials are also increasing. Only one item of shoemaking materials, the midsole, inner lining, toe lining, heel lining, etc. in each pair of shoes, will have non-woven fabrics. The types of collection include stitching, needle punching, spunbonding Nonwovens and chemical bonding, among shoemaking materials, the annual consumption of nonwovens in the country exceeds 40,000 tons. [0003] While gradually accepting the quality and performance of non-woven fabrics, various application fi...
