Description

Textiles containing porous materials and methods for manufacturing the same {YARNS WITH COFFEE RESIDUE AND PREPARATION THEREOF}

The present invention relates to a textile product containing a porous material, a method of manufacturing the same, and a textile material textile material.

In recent years, the design and research of functional fabrics that can perform calorie control according to the temperature of skin has attracted more and more attention. This is because human activity produces an odor that can be unpleasant to the environment. The properties of these gases differ not only from the physical state and chemical properties of the gas grains or from the causes of formation (biodegradation, chemicals, smoking, etc.), but also clearly distinguishable. In addition, these unpleasant odors can occur in our daily living spaces and environments, such as bathrooms, kitchens, garbage, and closed environments filled with smoke. Therefore, people want to manufacture fabrics that have high performance, for example, properties of solvent resistance, or which provide better performance characteristics, and which retain these performance characteristics even after repeated use.

It is well known that various materials, such as textiles, clothing or clothing, may be processed to enhance the performance characteristics associated with such materials. Such performance characteristics include odor removal, humidity control, UV protection, and / or the prevention of external factors.

At present, the textiles having an odor removal function are mostly provided using activated carbon to achieve the object. These include different types of activated carbon, such as activated carbon in the form of palm layer, spherical activated carbon, fibrous activated carbon, and activated carbon chemically treated on the surface. The size of the grains also varies greatly, and the grain sizes are different because of different manufacturing methods. Since activated carbon has a high surface area ratio, it shows high adsorption capacity, and there are cavities having various sizes in a shape covering the surface. These cavities are used to remove odors. The adsorption targets are mainly nonpolar polymers and saturated molecules, for example, benzene, toluene and methanethiol.

As a known technique, the method of injecting activated carbon into a garment is as follows.

1. Insert activated carbon pellets between the double layer fabrics. The fibers produced in this way are relatively heavy, and the clothing is not light and thus the comfort is low.

2. Cover the surface layer of the fiber with activated carbon. This approach can alter the physical properties of the fiber.

3. A mixture of activated carbon and adhesive is used to bond activated carbon onto fabric. According to this method, the activated carbon powder is covered by the adhesive, so there is a difference in the odor removal performance and cannot be washed out with water.

4. The main material of activated carbon fiber is used to make chemical synthetic fiber material and to make fabric. According to this method, the weight ratio of activated carbon added is relatively low, and the odor removal effect is limited.

5. The double or triple layer fabrics made by processing carbon fiber fabrics made of polyacrylonitrile (PAN) to act as adsorbents have excellent adsorption effect, but they are expensive and used for military defense clothing. Both the touch and the weight are unsuitable for use in normal fabrics.

The process for producing a textile article containing a porous material provided by known techniques has the problems listed below.

1. The intercalation of activated carbon granules in the middle of the bilayer fabric is relatively heavy in the fabric produced by this method, the clothing is not light, and the comfort is low.

2. Apparel made from materials is limited to the physical properties associated with the untreated material.

3. After using the chemical reagent, the chemical reagent is frequently volatilized, so it is necessary to reapply the chemical reagent continuously during the whole fabric manufacturing process to obtain the desired characteristics.

In view of this, the above-described prior art has many defects, and the inventor of the present invention has found various defects and disadvantages derived from the above-described prior art. As a result, the repetitive addition and consideration of the improvement resulted in the successful development of the textile material containing the porous material of the present invention and its manufacturing method.

In order to achieve the above and other objects, the method for producing a textile article containing a porous material of the present invention comprises the steps of (1) providing a porous material; (2) mixing the material with the polymer particles to produce a mother particle; (3) extracting yarn from the parent grains to form a yarn; (4) uniformly mixing the porous material in the solution; (5) homogeneously mixing the porous material in the solution; (6) Resin compound is used for foaming, crosslinking, catalyst and catalyst adjuvant, among which resin is polyurethane, polyacrylate, polyethylene terephthalate, polycarbonate ); (7) mixing the products of (5) and (6) to generate mechanical or chemical foam and form a foam; (8) applying the foam to the textile surface; (9) drying the textile product and (10) performing a crosslinking reaction. The porous material may be zeolite, coffee grounds, silicon dioxide, activated carbon, hollow material, activated carbon fiber, polymer nano-co-materials, and the like. In the present invention, the porous material is preferably zeolite or coffee grounds. Among them, the coffee grounds may be coffee grounds that have undergone red pears, coffee grounds that have undergone microencapsulated red pears, or carbonized coffee grounds, which are treated and mixed into a solution in powder. The mixed solution formed by the porous material and the solution may include other powders such as cold powder, moisturizing powder (for example, collagen), warming powder or extract powder, or liquid refining liquid (for example, coffee extract tablet liquid). The solution may be water. The adjuvant may be a foaming agent, a crosslinking agent, a catalyst or a foam stabilizer, the foaming agent may be a stearic acid, and the crosslinking agent may be an isocyanate. The ratio of a polyurethane resin compound and an adjuvant is as follows. 1% to 100% polyurethane resin compound, 0.05% to 5% foaming or blowing agent, 0.05% to 10% foam stabilizer and 1 to 10% other auxiliary. The other auxiliary agent may be a viscosity reducing agent, a thickening agent, a hydrophobic aid, an absorbent aid, a dispersant, a surface modifier (for example, a lead agent, a lubricant, a colorant, a filler, etc.). have.

The adjuvant of the present invention may have a different function, of which the main adjuvant, the foaming agent may be a surfactant and is used to achieve a foaming effect on the aqueous resin through the shear force. The blowing agent allows the gas produced at high temperature 100 to achieve the foaming effect. The crosslinker can provide good physical properties to the aqueous resin after high temperature treatment, increasing the degree of mechanical strength and water resistance. The foam stabilizer is a compound of stearic acid amines, and its purpose is to maintain foam stability after foaming of an aqueous resin. The catalyst maintains the triple reaction steady balance by controlling the polymerization reaction rate between isocyanate and hydroxyl group, between isocyanate and water, and isocyanate itself. Other adjuvants may be viscosity reducing agents, thickeners, hydrophobic aids, absorbent aids, dispersants, surface modifiers (eg, lead reducing agents, lubricants, coloring agents, fillers, and the like).

Among these, thickeners are used to increase the viscosity of the resin and to make it suitable for any processing. The use of viscosity reducing agents is intended to keep the adhesive surface of the finished product clean and free of adhesive. The use of a hydrophobic adjuvant is to make the surface of the resin non-hydrophilic so that it is not easily soiled. The dispersant disperses the auxiliary powder in the resin and evenly disperses the powder so that the function of the powder can be revealed on the surface of the resin. The function of the water absorbent resin is to improve the hydrophilicity of the resin to increase the moisture permeability. A lead sensitizer causes a feeling of oiliness to appear on the surface of the resin, and a lubricant sensitizes the touch of all on the surface of the resin. The colorant causes the coated surface to show a different color, and the filler produces the effect of preventing light reflection of the resin.

After the mixture of the present invention is mixed, foaming is performed by mechanical or chemical methods, among which the mechanical method is a polyurethane, polyacrylate, or polyethylene having foaming ability by using the force of the machine. Terephthalate Poly (ethylene terephthalate), polycarbonate (Polycarbonate) is injected into the air to form a foam through the shear force. The chemical method uses a material that generates bubbles by heat, such as a blowing agent, to foam itself under high temperature. In both methods, the foam ratio produced may be 0.1 to 50 times, and when the foam is applied to the cloth surface, the coating amount of the foam is 0.5 to 500 g / m 2. The foaming ratio of the foam body can be adjusted differently depending on the amount of foam body coating. The purpose of the application is to make absorbent or hydrophobic textiles, which may be by plain woven fabric, woven fabric, nonwoven fabric or thin film or release paper.

The present invention processes the foam formed after mixing the resin compound on the textile product, the manufacturing process of the processing is a procedure such as coating, water removal, baking and crosslinking, the textile is entered into the coating equipment, the coating equipment is a roller and The coating device, including the coating device, applies the foam body of the present invention onto the textile material, and the textile material coated with the mixture coating material of the present invention is passed through an oven at a temperature of 50 to 150 for 10 to 240 seconds.
