Detailed Description
The following is a specific embodiment of the present utility model, and the technical solution of the present utility model is further described with reference to the accompanying drawings, but the present utility model is not limited to these examples.
Example 1
A water-repellent ultraviolet-proof fabric is shown in fig. 1, and comprises a base fabric 1 and an outer coating 2 arranged on the outer surface of the base fabric 1.
It will be understood that the base fabric 1 macroscopically shows a flat structure, and microscopically as shown in fig. 2, is a grid-like structure formed by interweaving warp and weft base yarns, and is based on the thickness of the base yarns, so that the thickness of the interweaving portion of the base yarns serving as warp yarns and the base yarns serving as weft yarns is generally greater than the thickness of the interweaving portion of the base yarns serving as non-warp yarns, and therefore the base fabric 1 microscopically shows a certain convexity. In the application, the base yarns comprise the fiber yarns 11 and the ultraviolet-proof layer 12 coated on the outer surfaces of the fiber yarns 11, and the base fabric 1 woven by the base yarns with ultraviolet-proof performance not only has the ultraviolet-proof performance, but also does not remarkably increase the thickness of the fabric. Such a base yarn may be obtained by: the fiber yarn 11 is immersed in the ultraviolet-proof paint for a period of time, so that the fiber yarn 11 absorbs a certain amount of the ultraviolet-proof paint, and then the ultraviolet-proof paint is taken out for air drying, and the ultraviolet-proof paint is dried and solidified on the surface of the fiber yarn 11 to obtain the ultraviolet-proof layer 12. The selection of the fiber yarn 11 is not limited, and considering the strength of the fabric, the fiber yarn 11 can be any one of terylene, chinlon and nylon ammonia, or any two of the twisted yarns, or the twisted yarns of the three fibers. The ultraviolet-proof coating is not limited, and textile ultraviolet-proof finishing agents such as ultraviolet-proof finishing agent HTUV or VA400 which are available in the market can be adopted.
The outer coating 2, as shown in fig. 3, microscopically includes a waterproof coating substrate 21, and a plurality of ultraviolet shielding particles 22 dispersed in the waterproof coating substrate 21, and achieves both waterproof and ultraviolet shielding functions by a one-layer coating structure. Such an overcoat layer 2 can be obtained by the steps of: the ultraviolet shielding particles 22 are added to the liquid phase waterproof paint and stirred uniformly so that the ultraviolet shielding particles 22 are uniformly dispersed in the waterproof paint, then the mixture is coated on the outer surface of the base cloth 1, the waterproof paint is dried and cured to be the waterproof paint base 21, and the waterproof ultraviolet shielding particles 22 are uniformly dispersed in the waterproof paint base 21 based on the uniform stirring described above. Wherein generally 5 parts by mass of the ultraviolet shielding particles 22 are added to 100 parts by mass of the waterproof coating material. The choice of the waterproof coating material base 21 is not limited, and in this embodiment, a polyurethane waterproof coating material is used, and a polyurethane cured body, preferably polyurethane with good transparency, which is a conventional waterproof coating material, is obtained by curing. The waterproof ultraviolet particles 22 are not limited, and can be nano silicon dioxide, and the reflectivity of the nano silicon dioxide to ultraviolet rays with the wavelength of 490nm is as high as 70% -80%; meanwhile, the nano silicon dioxide can provide certain surface roughness for the fabric, and the hydrophobic effect is improved. The water-resistant ultraviolet particles 22 may also be nano-titania, preferably nano-titania particles having a particle size of less than 100nm, which primarily absorb ultraviolet light in the medium wavelength region, and the nano-titania also has a reflective capability for ultraviolet light in the long wavelength region. It is also known that the ultraviolet resistance of titanium dioxide is related to the particle size, and the reflection is dominant when the particle size is large and the absorption is enhanced when the particle size is small, so that it is preferable to use nano titanium dioxide particles having a high particle size distribution, such as nano titanium dioxide including both 20nm and 50 nm. The waterproof ultraviolet particles 22 may be a mixture of nano-silica and nano-titania.
The fabric provided with the outer coating 2 on only one side in this embodiment can be used for manufacturing sunshades, non-intimate apparel, etc.
Example 2
The water-repellent ultraviolet-proof fabric comprises a base fabric 1, wherein an outer surface of the base fabric 1 is provided with an outer coating 2, and an inner surface of the base fabric 1 is provided with an isolation layer 3, as shown in fig. 4. Wherein the structure of the base fabric 1 and the overcoat layer 2 is the same as in example 1. The isolation layer 3 is additionally arranged, so that the contact between the inner surface of the base cloth 1 and the outside can be blocked, the abrasion of the ultraviolet-proof coating 12 on the base cloth 1 is reduced, and the ultraviolet-proof performance of the fabric is further ensured.
In this embodiment, the separation layer 3 is a hydrophilic coating, and when the fabric is used for making clothes, a certain moisture absorption effect can be exerted, so that the wearing comfort is improved. The isolating layer 3 is obtained by coating hydrophilic paint on the inner surface of the base cloth 1 and then drying and curing, wherein the hydrophilic paint can be a textile hydrophilic finishing agent which is available in the market, such as HOLPOSON mm SMART CLEAN.
Example 3
The water-repellent ultraviolet-proof fabric comprises a base fabric 1, wherein an outer surface of the base fabric 1 is provided with an outer coating 2, and an inner surface of the base fabric 1 is provided with an isolation layer 3, as shown in fig. 4. Wherein the structure of the base fabric 1 and the overcoat layer 2 is the same as in example 1.
As shown in fig. 5, the separation layer 3 in this embodiment is an inner fabric formed by interweaving warp and weft of moisture-absorbing yarns, so that abrasion of the ultraviolet-proof coating 12 on the base fabric 1 can be avoided, and a certain moisture absorption effect is exerted. Meanwhile, the base cloth 1 and the lining cloth are formed by interweaving yarns in warp and weft, and the base cloth 1 and the lining cloth have a certain concave-convex structure in microcosmic, so that the side edges of the base cloth 1 and the side edges of the lining cloth are sewn and fixed only by simply superposing the base cloth 1 and the lining cloth, interweaving positions of the base yarns of the base cloth 1 correspond to interweaving positions of the moisture absorption yarns of the lining cloth, non-interweaving positions of the base cloth 1 correspond to non-interweaving positions of the lining cloth, a tiny air cavity 4 can be naturally formed, and after sweat of skin is absorbed by the moisture absorption yarns of the lining cloth, the air cavity 4 can give sweat volatilization space.
Wherein the choice of the absorbent yarn is not limited, for example, as shown in fig. 6, the absorbent yarn includes a straightened core wire 31 and an absorbent wrap wire 32 spirally wound around the core wire; the core wire 31 is formed by twisting energy storage fibers 311 and hygroscopic heating fibers 312. When the sweat absorbing and heating device is used, sweat absorbed by the moisture absorbing and wrapping wire 32 is transferred to the core wire 31, and the moisture absorbing and heating fiber 312 in the core wire 31 can rapidly heat after absorbing the sweat transferred by the moisture absorbing and wrapping wire 32 and transfer heat to the energy storage fiber 311 to realize heat preservation. The moisture absorption envelope 32 may be one of bamboo fiber, cotton fiber and flax fiber; the hygroscopic and exothermic fiber 312 can be one or more of Softwarm fiber, warmsensor fiber and Thermogear fiber, which are all commonly used in the prior art; the energy storage fiber 311 is obtained by coating a phase change material on the outer surface of a common fiber yarn, and the phase change material can be various phase change energy storage materials commonly used in the prior art, such as acrylonitrile/methyl acrylate copolymer, polyurea phase change microcapsule and the like.
