Embodiment A

[0465] Polyhexamethylene biguanide 1%, silver 0.15%, organosilane (dimethyloctadecyl[3-(trimethoxysilyl)propyl]ammonium chloride) 0.8%, propiconazole 0.15%, and Polyglucosamine (polyglucosamine) 1%.

Embodiment B

[0467] Polyhexamethylene biguanide 0.35%, silver 0.15%, organosilane (dimethyloctadecyl [3-(trimethoxysilyl) propyl] ammonium chloride) 0.8%, propiconazole 0.15%, both relative to the weight of the cloth.

[0468] This composition is added to water. For specific details of the liquors and individual compositions, reference is made to the description below.

[0469] Cloths are used in two examples, each representing a different composition:

[0470] Example A:

[0471] Select 100% cotton cloth with a cloth weight of 265 g / m2 and a width of 150 cm. Cloths may be used in water filtration applications as described below, for example referred to as "water filter cloths" in this specification.

[0472] Example B:

[0473] A blend of 35% cotton and 65% polyester is selected, the weight of the fabric is 200 g / m2, and the width is 150 cm. The resulting cloth can be used to produce eg clothing, for example referred to in this specification as "cloth for clothing".

experiment example

[0499] The inventors of the present application conducted further comprehensive experiments to determine the relationship between different process parameters and the results obtained when various antimicrobial agents were used alone or in combination. Unless otherwise specified, the cloth material used in each experimental example is a cotton-polyester blended cloth (number of yarn counts, warp yarn 20s, weft yarn 20s, polyester and cotton blended dyed cloth (65% polyester and 35% cotton), light sky blue, width 150cm, fabric weight 210g / m 2 ). Unless otherwise stated, chemical concentrations are in percent by weight of fabric (% o.w.f.) or gpl (grams per liter). Some fabrics were made as described below, while others were made under laboratory conditions that closely mimic the method of the present invention.

[0500] The antimicrobial activity of the fabric is measured in accordance with AATCC Test Method 100-2012. Prior to testing, the fabrics were cut into 2 x 4 inch pi...

Abstract

The invention relates to a method of manufacturing a textile material with antimicrobial compounds in such a manner to chemically bind or attach said compounds to the textile material, and to the treated textile material which performs as a disinfectant or sterilizer on its own. The treated textile material exhibits wash- durability and non-leaching properties. The process comprises an exhaust process cycle comprising the steps of treating the textile material using an exhaust process, wherein the liquor comprises one or more antimicrobial agents, and subjecting the treated textile material toa heat treatment. The invention further relates to a device for purifying water, which can operate based on gravity and without electricity.

Description

technical field [0001] The present invention relates to a method of making or treating a fabric, such as cloth, yarn and / or fibers, using an antimicrobial compound chemically bonded or attached to the fabric. The present invention also relates to the above-mentioned treated cloth, so that the cloth itself can be used as a disinfecting cloth or a sterilization cloth. Fabrics treated with the present invention exhibit washfastness and non-leaching properties. The invention also relates to a device and a system for purifying water by filtering out particles and / or microorganisms. The device and / or system preferably operates based on gravity and does not require electricity, so that the device and / or system can be used in areas where the power supply is unstable, such as in underdeveloped countries. Background technique [0002] Disinfection / sterilization is a very important work in daily life. It is rated in various grades. There are various records of requirements for diff...
