Description
Technical field
The present invention relates to a kind of method of preparing porous material textiles, and a kind of textiles of porous material.
Background technology
In recent years along with scientific and technological progress and the raising of quality of life, people also improve for the requirement of daily living article thereupon, comfortable and healthy functions for clothing is paid attention to more, and the progress along with technology, the people in this field attempts preparation and has the textiles of difference in functionality characteristic, as: he inhales smelly, ventilative, cool feeling, heat storing and heat preserving, thoroughly wets, the function such as water pressure resistance.
Mostly the known textiles with deodorization functions is to reach this object with activated carbon at present, the activated carbon that it comprises different shape, as: coconut husk stratiform activated carbon, spherical activated carbon, fibrous type activated carbon and the activated carbon of surface through chemical treatment, its granular size also differs widely, its granular size is because of different manufacture methods differences, because activated carbon has high-specific surface area, therefore adsorption capacity is large, its surface coverage has shape, the hole varying in size, this hole makes it have the function of deodorizing, its absorption object be take nonpolar large molecule and saturated molecule as main, as: benzene, toluene and methyl mercaptan etc.
In known technology, activated carbon is added to the method in clothing, have following several mode: 1. active carbon particle is clipped in the middle of two-layer fabrics, so the fine thing of preparation is more thick and heavy in this way, wears not lighter, and comfort level is low; 2. activated carbon is mixed to the cover layer into coating cotton thread, so this mode can change the physical property of yarn; 3. activated carbon is mixed with adhesive agent, activated carbon is attached on fabric, because the activated carbon powder agent that gets adhered is coated, therefore deodoriging properties is poor, and not water-fastness; 4. utilize activated carbon fiber raw material for main material, chemical synthetic fiber is auxiliary material, prepared fabric, and the activated carbon weight rate that so the method is added is low, therefore its deodorizing effect is limited; With 5. utilize carbon cloth that polyacrylonitrile (polyacrylonitrile is called for short PAN) does as adsorption material, laminating is machined to the fabric of two layers or three-decker, there is good adsorption effect, but expensive, be applicable to military's protective clothing, the neither application that is suitable for general fabrics of feel and weight.
Because every shortcoming of known technology, and people are to demand more comfortable, healthy clothing, research and develop a kind ofly there is better deodorization functions, more comfortable fabric is the people's in this field target, to develop the product that meets public demand.
summary of the invention
The present invention relates to a kind of method of preparing the textiles that contains porous material, it comprises: (1) forms mixture by the solution of porous material and mixed with resin; (2) mixture of (1) is formed to foams; (3) foams of (2) are coated to textile surface; And the textiles of (4) dry (3).Wherein resin is polyurethane (Polyurethane), polyacrylate (Polyacrylate), polyethylene terephthalate (Poly (ethylene terephthalate)) or Merlon (Polycarbonate).
In the inventive method, porous material is including but not limited to zeolite, coffee grounds, silica, activated carbon, mesopore material, activated carbon fiber, high molecular nanometer porous material ... etc., preferably porous material is zeolite or coffee grounds, wherein coffee grounds can be from the coffee grounds of baking and banking up with earth, the coffee grounds that microencapsulation was baked and banked up with earth or the coffee grounds of carbonization, the treated powder that forms is mixed in solution, the mixture that porous material solution forms, it can separately comprise powder: cool feeling powder, moisturizing powder (as: collagen), hotness powder or any can be extracted into the Essence (as: coffee extracted Essence) of powder or liquid, and this solution is water.The mixture that porous material solution and resin form, it can separately comprise foaming agent, blowing agent, foam stabilizer, bridging agent or catalyst, and foaming agent can be stearic acid, bridging agent can be isocyanates (isocyanate), and polyurethane resin compound wherein and the ratio of auxiliary agent are as follows: 1%～100% polyurethane resin compound, 0.05%～5% foaming agent or blowing agent, 0.05%～10% bridging agent, 0.05%～2% catalyst, 0.05%～10% foam stabilizer and other auxiliary agent of 1～10%; Wherein other contained auxiliary agent can be antitackiness agent, tackifier, hydrophobicity auxiliary agent, water imbibition auxiliary agent, dispersant, surface modifier (as: wax sense agent, sliding sense agent, coloring agent, filler) ... etc.
