Description
Technical Field
The utility model relates to the technical field of textiles, in particular to a preparation method of multifunctional fibers, the multifunctional fibers prepared by the preparation method and application of the multifunctional fibers in fabrics.
Background
With the improvement of the living standard of people, people are increasingly paying attention to the comfort and the functionality of fabrics. In hot summer, the fabric with cool feeling is more and more popular, and the moisture-conducting and air-permeable performance is also important for the fabric, so that the fabric with moisture-conducting, air-permeable and cool feeling is better in wearing comfort, and the demand is gradually increased. The fabric moisture conduction allows moisture to reach from the portion of the fabric contacting the skin of the human body to the outer surface of the fabric contacting the air, which makes the outer surface of the fabric susceptible to bacteria in a hot and humid environment, which requires the outer surface of the fabric to have antibacterial ability. The nano titanium dioxide can well absorb ultraviolet light to generate electron-hole, and perform photocatalysis antibacterial, and the fabric added with the nano titanium dioxide has the effects of ultraviolet resistance and antibacterial performance.
On the other hand, the preform-hot drawing process enables to obtain fibers of the same shape as the preform of a controlled diameter by hot drawing the preform of a certain shape, and is suitable for mass production. And the blowing spinning drives the fiber to be formed through high-speed air flow, the blowing range is large in area, the obtained fiber is small in diameter, and the method is also suitable for large-scale production.
At present, researchers have carried out related researches on multifunctional fibers and fabrics thereof. The utility model patent application with the application number of CN202010536966.2 provides a processing method of cool sense ultraviolet-proof covered yarn, natural mineral substances and slices are spun together and then immersed in cool sense finishing agent to obtain cool sense fibers, ultraviolet-proof base materials are then put into ultraviolet-proof paint to obtain ultraviolet-proof fibers, the cool sense fibers and the ultraviolet-proof fibers are taken as outer covered yarns, and the antibacterial short fibers are taken as core yarns to be covered to obtain cool sense ultraviolet-proof covered yarns, and the covered yarns obtained by the process have cool sense and ultraviolet-proof functions at the same time, but the fibers and the yarns obtained by the process are all immersed or coated with spinning additional functional materials, so that on one hand, the process requires longer immersion time, is not suitable for mass production, and on the other hand, the obtained coating is easy to wear and loses functional effect. The utility model patent with the application number of CN202020588430.0 provides a unidirectional moisture-conducting ultraviolet-resistant nylon elastic yarn-dyed fabric, wherein a hydrophilic layer, a moisture-conducting layer, a cool sense layer and a fluff layer are sequentially arranged at the bottom of the outer layer of the fabric, and the outer layer is coated with a heat-resistant antibacterial coating. In another example, the application number of the utility model is CN202010665662.6, which provides a multifunctional flame-retardant fabric based on a binding double-layer fabric and a preparation method thereof, wherein the fabric is a surface layer obtained by interweaving first warp and weft yarns and an inner layer obtained by interweaving second warp and weft yarns, the surface layer and the inner layer are woven to obtain the binding double-layer fabric, and then hydrophilic finishing agent, cool finishing agent, antibacterial finishing agent, antistatic finishing agent, ultraviolet-resistant finishing agent and the like are respectively carried out on the double-layer fabric through padding and baking process to obtain the multifunctional flame-retardant fabric with moisture conducting, cool, antibacterial, antistatic and ultraviolet-resistant functions, but the multifunctional fabric obtained by the process has many functions which are finished through the finishing agent.
Disclosure of Invention
In view of the above, in order to overcome the defects of the prior art, one of the purposes of the present utility model is to provide a method for preparing a multifunctional fiber having various properties such as ultraviolet resistance, antibacterial property, cool feeling and ventilation.
In order to achieve the above purpose, the present utility model adopts the following technical scheme:
a preparation method of the multifunctional fiber comprises the following steps:
uniformly mixing the high polymer material slice doped with the carbon nano tube with the polyvinyl alcohol master batch, and heating and pressurizing to obtain a prefabricated member;
carrying out hot stretching on the prefabricated part to obtain mixed fibers, and placing the mixed fibers in water to dissolve polyvinyl alcohol in the mixed fibers in the water to obtain porous fibers doped with carbon nano tubes;
arranging porous fibers into a net curtain, blowing and spraying spinning solution on the porous fibers by adopting a blowing and spinning process on two sides of the net curtain, and forming a nanofiber layer to obtain the multifunctional fibers.
