Antimicrobial material comprising synergistic combinations of metal oxides
The present invention relates to methods and articles for wound healing involving the use of a material having antimicrobial properties, said material comprising a synergistic combination of at least two metal oxide powders, comprising a mixed oxidation state oxide of a first metal and a single oxidation state oxide of a second metal, wherein the mixed oxidation state oxide constitutes from about 0.05% to about 15% wt. of the total weight of the synergistic combination of the at least two metal oxide powders and wherein the ions of the metal powders are in ionic contact upon exposure of said material to moisture.
Functional-agent-containing fiber and method for manufacturing same
Functional agent-containing fibers according to an embodiment of the present invention, wherein a functional agent is supported by silicone fixed to the fibers. The silicone includes an acrylic-modified organopolysiloxane having two or more acrylic groups per molecule. A rate of decrease in the functional agent after the functional agent-containing fibers are washed 10 times is less than 40%. In the present invention, the functional agent-containing fibers may be produced, e.g., by irradiating fibers impregnated with a fiber treatment agent A containing silicone with an electron beam so that the silicone is fixed to the fibers, and impregnating the fibers to which the silicone has been fixed with a fiber treatment agent B containing a functional agent. The functional agent-containing fibers may be produced, e.g., by impregnating fibers with a fiber treatment agent C containing silicone and a functional agent and irradiating the fibers impregnated with the fiber treatment agent C with an electron beam so that the silicone is fixed to the fibers and the functional agent is supported by the silicone fixed to the fibers. Thus, functional agent-containing fibers having improved washing resistance and a method for producing the fibers are provided.
Multifunctional high-strength composite fabric coating agent, coating, method for preparing the same, and application thereof
A multifunctional high-strength composite fabric coating agent, a coating, a method for preparing the same and an application thereof are provided. The fabric coating agent includes a resin, a reinforcing agent with a reactive group, a bifunctional dispersing agent, a leveling agent, a film forming agent, a softening agent, an antibacterial agent, a solvent, and the like. The reinforcing agent is modified such that it has active functional groups of —OH and NH.sub.3. The fabric coating agent is not only easy to apply, fast to react and stabilize, but also suitable for a fabric surface of any material. A treated fabric has high tensile-breaking strength, excellent tearing and bursting performance, good waterproof-and-moisture-permeability and antibacterial performance, and high adhesion. It can be repeatedly knife coated, roll coated, calendared, or dipped. The method is not only mature in technology and low in production cost, but also suitable for large-scale application.
PROCESSES FOR CONVERTING TEXTILES AND ENHANCING THE FLUID REPELLANT PROPERTIES OF TEXTILES
Processes for converting textiles from water and oil absorbent textiles to water and oil repellent textiles and for treating textiles to increase fluid repellant properties of the textiles. The treated textiles may be used, for example, as PPE for healthcare workers that are faced with a shortage of PPE materials. The processes add a fluid repellant, such as a fluoropolymer-based fluid repellant, during a stage of a laundry process, for example at the sour stage. The fluid repellant may be added multiple times during a laundry process.
ANTIMICROBIAL MATERIAL COMPRISING SYNERGISTIC COMBINATIONS OF METAL OXIDES
The present invention relates to methods and articles for wound healing involving the use of a material having antimicrobial properties, said material comprising a synergistic combination of at least two metal oxide powders, comprising a mixed oxidation state oxide of a first metal and a single oxidation state oxide of a second metal, wherein the mixed oxidation state oxide constitutes from about 0.05% to about 15% wt. of the total weight of the synergistic combination of the at least two metal oxide powders and wherein the ions of the metal powders are in ionic contact upon exposure of said material to moisture.
FIBER CLOTH HAVING FUNCTIONAL COMPOSITE PARTICLES AND PREPARATION METHOD THEREFOR
The present application relates to fiber cloth having functional composite particles and a preparation method therefor. The preparation method comprises: placing a solid metal block consisting of functional metal particles into a crucible using an evaporation and condensation process, and heating and evaporating the same into a vacuum physical vapor deposition (PVD) process furnace for condensation; depositing PVD ceramic layers on the outer surfaces of the functional metal particles under the condensed state using a PVD process to form the functional composite particles; and screening the functional composite particles by means of a particle filter and accelerating the particles to bombard the fiber cloth, thereby implanting the functional composite particles into the fiber cloth to form the fiber cloth having the functional composite particles. The functional composite particles in the present application can reduce contact between the internal functional metal particles and external oxygen, slowly release ionic metal ions of the functional metal particles, and prolong the action time of the functional metal particles. According to the present application, by implanting the functional composite particles into the fiber cloth, the fiber cloth with a long lasting antibacterial effect can be obtained.
METHOD FOR PRODUCING INORGANIC PARTICLE COMPOSITE FIBERS
A method of producing inorganic-particle-combined fiber includes: a beating step including beating chemical fiber in a wet manner or a dry manner; and a composite fiber forming step including forming inorganic-particle-combined fiber which is composite fiber composed of the chemical fiber and inorganic particles, the composite fiber forming step including synthesizing the inorganic particles in a slurry that contains the chemical fiber after the beating step.
FIBER COMPLEXES AND PROCESSES FOR PREPARING THEM
The present invention aims to provide a technique for preparing a complex fiber covered by silica and/or alumina at a high coverage ratio. According to the present invention, complex fibers comprising silica and/or alumina deposited on the surface of a fiber at a high coverage ratio can be prepared by synthesizing silica and/or alumina on the fiber while maintaining the pH of the reaction solution containing the fiber at 4.6 or less.
PROCESS FOR THE PREPARATION OF FUNCTIONALIZED WEATHER-RESISTANT AND SLOW-DECAYING GEOTEXTILES
Processes for making weather resistant, slow-decaying, durable natural fiber/coir geotextiles produce geotextiles having flexibility, permeability, light weight and cost-effective characteristics. In this process an in situ chemical grafting using a mixture of Cashew Nut Shell Liquid and aminoalkyl trialkoxysilanes with cellulose was done followed by curing in presence of sunlight, UV light or heat. The developed product showed durability and strength more than that of natural fiber/fabric and retaining natural fiber/fabric/geotextiles characteristics. The geotextiles have delayed bio-deterioration having wider long-term end use/applications. This process of making durable geotextiles is eco-friendly and retains the desired characteristic.
FIBER-TREATING AGENT
This fiber-treating agent includes a nitrogen-atom-containing polysiloxane synthesizable from an inexpensive raw material and excelling in preservation stability that is represented by formula (1) and/or a reaction product of the nitrogen-atom-containing polysiloxane with an epoxy compound. This fiber-treating agent makes is possible to add good flexibility and highly durable water-absorbing properties to a fiber.
