Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of woven fabrics, and particularly relates to a sunscreen antibacterial fabric. Background Art
[0002] Sun-protective clothing can effectively block the direct irradiation of solar ultraviolet rays and reduce the damage of ultraviolet rays to the skin. Most of the common shuttle-woven sun-protective clothing on the market is made of polyester fabric, which has good sun protection ability, but poor air permeability. In hot summer with a lot of sweating, the sun-protective clothing is soaked and stuck to the body by sweat, and the sweat cannot evaporate in time, resulting in the accumulation of moisture inside the clothing and inability to be discharged in time, which is easy to breed bacteria and produce odors, affecting the wearing comfort. Content of the Utility Model
[0003] The purpose of the utility model is to provide a sunscreen antibacterial fabric, aiming to improve the problems of poor air permeability and easy bacterial breeding of conventional shuttle-woven sunscreen fabrics.
[0004] To achieve the above purpose, the technical solution proposed by the utility model is as follows:
[0005] A sunscreen antibacterial fabric includes a first polyamide fiber as the warp and a second polyamide fiber as the weft. The sunscreen antibacterial fabric is formed by shuttle weaving the first polyamide fiber and the second polyamide fiber according to a twill weave. The first polyamide fiber is a dull low-elasticity filament with an elasticity less than 30%, and the second polyamide fiber is a dull antibacterial filament.
[0006] Preferably, the first polyamide fiber is an ultra-fine fiber with a single filament fineness less than 0.44 dtex.
[0007] Preferably, the specification of the first polyamide fiber is 25D / 68F, and the specification of the second polyamide fiber is 20D / 24F.
[0008] Preferably, the tightness coefficient of the sunscreen antibacterial fabric is 140% - 150%.
[0009] Preferably, the twill weave is a cavalry twill.
[0010] Preferably, the warp float and weft float of the cavalry twill are both 1.
[0011] Preferably, the warp tissue points on the first warp yarn from left to right in the minimum tissue repeat of the cavalry twill are two up, one down, one up, one down; the warp tissue points on the second warp yarn are one down, two up, one down, one up; the warp tissue points on the third warp yarn are one up, one down, two up, one down; the warp tissue points on the fourth warp yarn are one down, one up, one down, two up; the warp tissue points on the fifth warp yarn are one up, one down, one up, one down, one up.
[0012] Preferably, the surface of the sunscreen antibacterial fabric has a slightly wrinkled structure.
[0013] Preferably, the density of the sunscreen antibacterial fabric is 111×78 threads / INCH, and the gram weight is 60g / m 2 .
[0014] With the above technical solution, the beneficial effects of the present utility model are as follows: The sunscreen antibacterial fabric of the present utility model is formed by shuttle weaving the first polyamide fiber and the second polyamide fiber as warp and weft yarns according to twill weave. The first polyamide fiber is a dull low-elastic yarn with an elasticity less than 30%, and the second polyamide fiber is a dull antibacterial yarn. On the one hand, it forms a microscopic air hole effect on the fabric surface, making sweat easier to transfer outward through the fabric, and the wearer feels comfortable and not sticky. On the other hand, it can not only retain the properties of the wire itself to absorb ultraviolet rays and reflect ultraviolet rays electronically, but also endow the fabric with a certain shading effect, having a deep sunscreen effect. At the same time, through the contact antibacterial property of the second polyamide fiber, the bacteria in contact with the fabric are effectively inactivated, endowing the fabric with antibacterial and odor-removing effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] Figure 2 It is the minimum tissue repeat diagram of the sunscreen antibacterial fabric of a certain preferred embodiment of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0017] The following further describes the present utility model in conjunction with the drawings and specific embodiments.
[0018] Combined with Figure 1 and Figure 2 , the sunscreen antibacterial fabric of this embodiment includes the first polyamide fiber as the warp yarn and the second polyamide fiber as the weft yarn. The sunscreen antibacterial fabric is formed by shuttle weaving the first polyamide fiber and the second polyamide fiber according to twill weave. The first polyamide fiber is a dull low-elastic yarn with an elasticity less than 30%, and the second polyamide fiber is a dull antibacterial filament.
[0019] The first polyamide fiber is an ultra-fine fiber with a single filament fineness less than 0.44 dtex and a specification of 25D / 68F, which can fully reflect its skin-friendly characteristics, endow the fabric with a cottony feel, and is skin-friendly and comfortable.
[0020] The specification of the second nylon filament is 20D / 24F. Nylon antibacterial filament is an antibacterial fiber prepared by blending and spinning with antibacterial powder. It has functions such as sterilization, bacteriostasis, and deodorization, and can be applied to products such as socks, underwear, towels, and dishcloths. The antibacterial powder used is a polarized nano-powder, which has the characteristics of high activity and strong bactericidal power. The antibacterial fiber developed with this powder has good whiteness, does not turn yellow or change color, is suitable for developing summer lightweight clothing, and has excellent anti-ultraviolet performance and anti-transparency characteristics. Nylon antibacterial filaments can choose brands such as SEK, LIVEHEALTH, Xinen, and Yiheng on the market. The weft yarn uses nylon dull antibacterial filament, which is contact antibacterial and can effectively inactivate bacteria that come into contact with the fabric, with a bacteriostatic rate of over 95%. After the fabric is soaked in sweat, it is not easy to breed bacteria and produce odors, ensuring the fresh characteristics of the fabric. At the same time, the safety of contact antibacterial is extremely high and will not cause any damage to the cells and beneficial bacteria in the human body.
[0021] Combined with Figure 1 , the twill weave of this embodiment is a cavalry twill, and its warp and weft floats are both 1.
[0022] Specifically as Figure 2 shown, the vertical grids represent warp yarns, the horizontal grids represent weft yarns, the black-filled grids represent the tissue points where the warp and weft yarns are interwoven, and the warp yarns float above the weft yarns. The minimum tissue repeat of the cavalry twill is formed by the interweaving of five warp yarns and five weft yarns. Among them, the warp tissue points on the first warp yarn are two up, one down, one up, one down for the warp yarn; the warp tissue points on the second warp yarn are one down, two up, one down, one up; the warp tissue points on the third warp yarn are one up, one down, two up, one down for the warp yarn; the warp tissue points on the fourth warp yarn are one down, one up, one down, two up for the warp yarn; the warp tissue points on the fifth warp yarn are one up, one down, one up, one down, one up for the warp yarn.
[0023] The manufacturing parameters are as follows: the loom width is 182 cm, the reed of 21.5 is used with 4 - end denting, the loom weft density is 70 picks, 10 harnesses are used for harnessing, and the 1 - 10 harnesses can be threaded in sequence. The dyeing and finishing method is air - jet cylinder slightly wrinkled dyeing. The surface of the sunscreen antibacterial fabric shows a slightly wrinkled structure. The finished product specification is 111×78 ends / inch, the effective width is 142 cm, and the gram weight is: 60 g / m 2 .
[0024] According to the formula for calculating the finished fabric tightness (coverage) coefficient:
[0025]
[0026] Among them, 0.01371 is the nylon correction coefficient.
[0027] Since the overall tightness of the cavalry twill of this embodiment is more inclined to the 1 / 1 plain weave, the tissue coefficient is 1.0.
[0028] The finished tightness (coverage) coefficient of the fabric in this embodiment:
[0029]
[0030] The finished tightness is 146%, belonging to high-tightness fabrics. Fabrics with high tightness coefficients are usually more water-repellent and protective than those with low tightness coefficients because these fabrics are denser, with less air volume in their internal voids, making it difficult for moisture and external substances to penetrate. The finished tightness of this application is 146%, belonging to high-strength and high-rigidity fabrics with excellent shielding properties. The total density of the fabric after dyeing and finishing is as high as 480 threads / INCH, making the fabric extremely rigid.
[0031] The warp and weft yarns adopt a combination of low-elasticity yarns and filaments. Dyeing and finishing (such as air-jet cylinder micro-crease dyeing) can more effectively wrinkle, combined with twill weave, which can form a microscopic pore effect on the fabric surface, making it easier for sweat to transfer outward through the fabric, dry and not sticking to the body. At the same time, the use of filaments for the weft yarn makes heat transfer more smooth, with a good cool feeling effect in skin contact, meeting the requirements of the national standard for smooth contact cool feeling. The fabric in this embodiment can form natural grooves and micro-crease effects after dyeing and finishing, making the fabric have excellent stiffness and dryness. Compared with conventional polyester fabrics, it has better air permeability and is comfortable to wear without sticking to the body.
[0032] The fabric achieves deep sun protection through three sun protection principles: absorption, electron reflection, and shielding effect. The dull polyamide fiber has a unique semiconductor effect, forming a microelectronic transition layer on the fabric surface, having a certain electron reflection effect on ultraviolet rays, and at the same time, it can effectively absorb ultraviolet rays. The high-tightness twill weave combined with dull filaments also has good light-shielding properties, with a UPF value of 100+ or more. No anti-ultraviolet additives (fluorescent agents) need to be added during the dyeing and finishing process, and it can be used by both infants and adults.
[0033] Although the present utility model has been specifically shown and described in combination with preferred embodiments, those skilled in the art should understand that various changes can be made to the present utility model in terms of form and details without departing from the spirit and scope of the present utility model defined by the appended claims, and all such changes are within the protection scope of the present utility model.
