The present invention relates generally to a multifunctional textile and the manufacturing method and use thereof, and more particularly to a multifunctional textile with high water repellency, soil repellency, oil resistance, fungus resistance and excellent fire retardancy formed by combining incompatible water repellent agent and flame retardant through special processes and the manufacturing method and use thereof.
With instant development of technology and continuous advancement of material science, people become aware of personal safety and safeguarding of assets gradually, how to protect personal key items properly to avoid irretrievable consequences of accidents is one of the key concerns of the consumers about buying products. At present, the flame retardant materials are used very extensively, the building materials, fabrics, plastic products or household appliances are provided with a flame retardant mechanism to avoid the property being burned down in a fire accident, bringing further protection and operational safety to the users. Therefore, many manufacturers began to develop relevant products.
In terms of conventional flame retardant mechanism for textiles, the flame retardant is usually coated on the textiles or yarns. However, most of the flame retardants do not have favorable adhesion for textiles, so the direct coating on the flame retardant textile is likely to be dissolved during water washing. Moreover, many consumers pay attention to the water repellent effect of textile products gradually in recent years, the textiles are expected to be waterproof, soil repellent and oil repellent. The existing water repellent agent fills the capillary bores in the object surface with fine chemical substances, so that the water, oil or other dirt cannot adhere to the surface, forming a water repellent effect, but most water repellent agent cannot be coated with flame retardant anymore. The existing waterproof and moisture permeable coating and fireproof and flame retardant coating are resistant to each other in processing programs in chemical principle, to keep good waterproof and moisture permeable effect on textiles, most of the textiles shall be processed with water repellent agent. Most of the existing water repellent agents are fluorocarbon additives, containing combustion-supporting carbon element, and the flame retardant reduces the adhesion amount of water repellent agent in the flame retardant coating processing. Therefore, it is quite difficult to add water repellent agent and flame retardant to the textile at the same time. Most of the manufacturers directly add flame retardant to the yarns before weaving the flame retardant and water repellent textiles, and the woven textile is coated with water repellent agent, but the flame retardant has permeated in the gaps in the yarns, inducing low adhesion of water repellent agent, which is likely to be washed out or dissolved.
To add flame retardant and water repellent agent to the fibers simultaneously and to keep persistently effective functionality, it is more difficult for traditional processes. Therefore, related suppliers stack up waterproof PL resin, brominated fire-proofing agent and wax smoothing agent to generate waterproof and flame retardant effect, the water repellent agent and flame retardant can be applied at the same time to achieve waterproof and fire insulation effect, but the processing program is complex and the effect is limited, the fire insulation and flame retardant effect may decline greatly after washing. In addition, related suppliers developed a fireproof and waterproof composite fabric structure, comprising a bearing layer made of polyester fiber, a flame retardant cotton layer made of modified polyacrylonitrile fiber and a waterproof layer made of polyethylene. The polyacrylonitrile fiber is made into flame retardant cotton layer by preprocessing, but the polyacrylonitrile fiber has worse alkali resistance, if it is washed with alkaline cleaning supplies by accident, the polyacrylonitrile fiber structure is likely to be damaged. Moreover, the polyacrylonitrile fiber is easy to soften at 190° C.˜230° C., it is difficult to be handled in fabric processing. In view of this, the bulk production of a dyeable, elastic and soil repellent synthetic fiber with high water repellent, flame retardant, moldproof and antibacterial effects becomes a major topic of current fiber textile processors.
Therefore, in the implementation spirit of careful study and creation, based on said technical problems, the inventor started research and development. With years' professional practice of creation and what learned from implementation, the inventor concentrated on research and development and put forth new ideas, so as to propose the present invention, hoping to enhance the advantages of this process and to remedy the known defects.
The main object of the present invention is to improve the process, reduce the material cost and produce a multifunctional textile with better water repellent and flame retardant effect.
The second object of the present invention is to provide the manufacturing method for a water repellent, soil repellent, oil repellent and moldproof multifunctional textile.
The third object of the present invention is to provide a water repellent and flame retardant textile with high texture formed by improving the process to enhance simultaneously effective adhesion of flame retardant and water repellent agent to the fabric and the manufacturing method thereof.
The fourth object of the present invention is to provide a multifunctional textile with water repellent and flame retardant effect, as well as linen type mesh and particular multi-color sense, which can adhere to the notebook computer casing surface, video box casing surface, tablet PC casing surface, mobile phone casing surface, desktop casing surface, the casing surface of sound boxes and other electronic products.
To attain said purposes, the multifunctional textile and the manufacturing method and use thereof of the present invention comprises a base cloth layer, a first composite layer, a second composite layer and a flame retardant layer. Wherein the base cloth layer is woven from a polyester fiber and a polyester cationic fiber, so that the base cloth layer has a first surface and a second surface opposite to the first surface. The first composite layer is disposed on the first surface of the base cloth layer. The second composite layer is disposed on the second surface of the base cloth layer. The flame retardant layer is disposed on the first composite layer. Wherein the first composite layer and the second composite layer at least contain 3 to 13 parts by weight of water repellent agent and 1 to 8 parts by weight of anti-mildew agent respectively. The flame retardant layer at least contains 40 to 60 parts by weight of phosphate ester, 38 to 55 parts by weight of ammonium phosphate and 2 to 5 parts by weight of butanone; or the flame retardant layer at least contains 85 to 95 parts by weight of polyphosphate ester and parts by weight of butanone.
