Abstract
The invention discloses a far infrared deodorization fabric and a preparation method thereof, and relates to the technical field of fabrics. When the far infrared deodorization fabric is prepared, firstly, propenyl pyromellitic acid and 2-amino-5-hydroxy propiophenone are wrapped with aminated carbon nano tubes to form a hyperbranched structure with tripropylamine as a center and polyimide as a branched chain, and far infrared fibers are prepared; then mixing a polypropylene prepolymer obtained by polymerizing acrylic acid-based o-nitroaniline with active carbon to prepare deodorant fibers; finally, the far infrared fibers are used as weft yarns, the deodorizing fibers are used as warp yarns, hot rolling is carried out after weaving, and o-hydroxy benzotriazole is formed to prepare the far infrared deodorizing fabric; the far infrared deodorization fabric prepared by the invention has good fracture toughness, tensile strength, water washing resistance and far infrared radiation performance.
Description
Technical Field
The invention relates to the technical field of fabrics, in particular to a far infrared deodorization fabric and a preparation method thereof.
Background
The solar rays can be roughly divided into visible light and invisible light. The visible light can refract the light rays with the colors of purple, blue, cyan, green, yellow, orange and red after passing through the triangular mirror. The light outside the red light, a portion of the spectrum having wavelengths from 0.76 to 400 μm, is called infrared light, also called infrared light. Infrared rays belong to the category of electromagnetic waves, and are radiation rays having a strong thermal action. The wavelength range of infrared rays is wide, and people divide infrared rays in different wavelength ranges into near infrared, intermediate infrared and far infrared regions, and electromagnetic waves with corresponding wavelengths are called near infrared, intermediate infrared and far infrared. Far infrared radiation materials with radiation properties were found in the 40 s and were mainly used for heat treatment, setting and curing, dehydration and drying of objects. The radiant heat energy of the far infrared radiation material can reduce the energy consumption (heat energy, electric energy and the like) required by heating objects, improve the production efficiency and realize the automation of the production process. Is often used in the industrial fields of coating, printing, food, medical treatment, textile and the like.
The far infrared textile health care product is a new functional textile product developed abroad in recent years. The technical principle is that carbon nanofibers, metal oxides and other specific wavelength high-radiation-rate far infrared radiation materials are carried on textile fabrics, and by absorbing human body heat, far infrared rays are radiated to act on a human body to generate resonance absorption and penetrate cortical tissues, so that medical, health-care and cold-proof effects of improving the microcirculation of the body surface, promoting metabolism, improving the surface temperature of the human body and the heat preservation of the textile fabrics are achieved. In the use process, technicians find that after the indoor temperature rises, gas generated by the breathing activity of indoor people is easy to ferment to form odor, so that the problem is solved by adding active carbon into the textile, and meanwhile, the problems of poor mechanical property, great reduction of far infrared radiation performance of the textile and the like are also brought.
The invention focuses on the phenomenon, finds that the curtain in the indoor soft-package textile often contacts outdoor sunlight, and can solve the problem by preparing the far infrared deodorization fabric and fully utilizing the sunlight to enhance the far infrared radiation performance of the curtain.
Disclosure of Invention
The invention aims to provide a far infrared deodorization fabric and a preparation method thereof, and aims to solve the problems in the prior art.
In order to solve the technical problems, the invention provides the following technical scheme:
the far infrared deodorization fabric is prepared by weaving far infrared fibers serving as weft yarns and deodorization fibers serving as warp yarns and then performing hot rolling.
Furthermore, the far infrared fiber is prepared by wrapping and ammoniating a carbon nano tube by propenyl pyromellitic acid and 2-amino-5-hydroxy propiophenone.
Further, the deodorizing fiber is prepared by mixing a polypropylene prepolymer and activated carbon.
Furthermore, the polypropylene prepolymer is prepared by mixing ethyl chloroacrylate and o-nitroaniline.
Further, the preparation method of the far infrared deodorization fabric comprises the following preparation steps:
