The outer layer of the cotton fiber 2 is also provided with a fluorescent whitening agent layer 4, and the fluorescent whitening agent layer 4 is positioned in the inner layer of the ultraviolet absorbent layer 3. The thickness of the cotton fiber 2 is 30-50D. The hairiness amount of the cotton fabric layer 1 is 10-20 pieces/m2。
The application embodiment 1 is that the implementation principle of a functional fabric with high ultraviolet radiation resistance and color fastness is as follows: the cotton fiber 2 is rinsed for three times by clear water after alkali treatment and dried, so that the color fastness of subsequent dyeing can be improved. And dyeing by using a fluorescent whitening agent and a dyeing agent so that the fluorescent whitening agent is coated on the outer layer of the cotton fiber 2. Then the cotton fiber 2 passes through the ultraviolet absorbent again, so that the ultraviolet absorbent is coated on the outer layer of the cotton fiber 2. Therefore, the prepared fabric can absorb invisible ultraviolet light. After the ultraviolet absorbent is coated, the color inside the ultraviolet absorbent is not easy to wash away, and the color fastness is high. In addition, the whole fabric is light and thin, and is not easy to deform after being washed by water. And weaving the treated cotton wheel fibers into a cotton fabric layer. And finally, the cotton fabric layer is processed by using sanding equipment to reduce hairiness and impurities, so that the effects of softness and portability are achieved.
Example 2
The functional fabric body has a two-layer structure, as shown in fig. 2, and comprises an antibacterial layer 8 besides a cotton fabric layer 1, wherein the antibacterial layer is formed by weaving Sirofil yarns 5. As shown in fig. 3, the sirofil 5 yarn is composed of a core yarn 6 and a covering yarn 7, and the covering yarn 7 is spirally wound on the outer layer of the core yarn 6 with a gap therebetween. The twist range of the Sirofil yarn 5 is 300-. Therefore, the yarn formed by the sirofil spinning has good air permeability and good moisture-discharging performance, and can meet the requirement of antibiosis.
In this example 2, two core yarn 6 materials are used, one is water-soluble polyvinyl alcohol fiber, and the other is a mixed fiber formed by twisting tencel staple fiber and water-soluble polyvinyl alcohol staple fiber. As shown in fig. 4, the core yarn is formed by circularly connecting three sections, wherein the first section 61 is a water-soluble polyvinyl alcohol fiber section, the second section 62 is a transition section in which the water-soluble polyvinyl alcohol fiber and the mixed fiber coexist, and the third section 63 is a mixed fiber section; and repeatedly and circularly connecting the three sections of yarns to form the yarns. The water-soluble polyvinyl alcohol short fibers in the core yarn 6 can be dissolved in water, so that the final sirofil spinning structure is fluffy and the air permeability and the moisture-removing performance are good.
The covering yarn 7 is made of nylon ATY filament which has air holes, so that the nylon ATY filament has good air permeability and moisture-removing performance and can be used as one of raw materials of the antibacterial layer.
The cashmere fiber and the polyamide ATY filament can be selected from the same color system or different color systems. When different color systems are selected, the color of the functional fabric body can be richer, and the problem of single color of protective clothes in the related art can be solved.
The implementation principle of embodiment 2 of the present application is as follows: firstly, blending 50-65% of tencel short fiber of one color and 35-50% of water-soluble polyvinyl alcohol short fiber to prepare roving, namely the used mixed fiber; and (3) making the water-soluble polyvinyl alcohol fiber into roving.
