Abstract
The invention relates to the technical field of textiles and discloses a production method of a new energy automobile headrest, which consists of a pillow core and a pillowcase, wherein the pillow core is made of polyurethane sponge, the pillowcase is made of composite fabric through cutting and sealing technology, the composite fabric comprises polyethylene terephthalate, boron nitride-luffa composite and functional elastomer, and the new energy automobile headrest can be obtained by premixing raw materials, extruding, granulating, slicing, spinning, oiling, winding, braiding and shaping operations to obtain the composite fabric with excellent performances of ventilation, heat dissipation, wear resistance, antibacterial and the like, stacking the composite fabric, sealing and cutting the composite fabric, and filling the pillow core.
Description
Technical Field
The invention relates to the technical field of textiles, in particular to a production method of a new energy automobile headrest.
Background
In recent years, in order to respond to the development strategy of sustainable development, new energy automobiles are rapidly developed, and in order to make products more attractive to consumers, manufacturers are increasingly deeply researching automobile interiors, and the headrest is used as a ring of the interior, so that the automobile is attractive, the driving comfort is greatly influenced, and the automobile has higher research value. In hot summer, the new energy vehicle owner who has mileage anxiety often chooses to close the air conditioner, cool down through the mode of opening the door window, and in long-term driving process, for more comfortable, most drivers can be with the head pillow on the headrest, under the condition that does not open the air conditioner, the long-term contact of head can lead to sweat stain to remain with the headrest, this kind of moist environment breeds the bacterium easily, can not only lead to the headrest to go moldy, it is pleasing to the eye still can produce sweat stink, influence driving experience consequently, therefore, new energy vehicle's headrest should have good antibacterial property, heat dissipation and gas permeability, just can better satisfy market demand.
The invention patent with publication No. CN113622193B discloses an antibacterial pillow, which is characterized in that cotton fibers are sequentially soaked in PVA aqueous solution, modified graphene oxide solution and silver nanowire solution, and the cohesiveness of the PVA aqueous solution is utilized to promote good cohesiveness of graphene oxide and silver nanowires and the cotton fibers, so that good antibacterial property and antibacterial durability of the pillow are ensured, but the cotton fibers have low heat conductivity and are difficult to dissipate heat, and the cotton fibers have wear resistance and are easy to pill, so that the antibacterial pillow is difficult to popularize as a pillowcase material of the novel energy automobile headrest.
