Description
Technical Field
The invention relates to the technical field of fabrics, in particular to an ultraviolet-proof and antibacterial fabric and a preparation method thereof.
Background
Textile fabric is a common light industrial product of daily life, in the past because the standard of living is lower, textile fabric as long as satisfy characteristics such as durable sense of touch is good can, along with the improvement of standard of living now, people tend to the diversification to textile fabric's function, also more and more high to textile fabric's functional requirement, be similar to this kind of function that is favorable to physical and mental health of antibacterial function also becomes consumer's demand, along with the improvement of consumer's safety consciousness in addition, also has required textile fabric's flame retardant property.
Polyvinyl acetal fiber is also called vinylon fiber, and has a relative density of 1.26-1.30 g/cc, a softening point of 220-230 ℃, and a softening point in water of 110 ℃; the fineness of the cotton fiber type short fiber is 1.4 deniers; the dry and wet strength is 5.4 gram force/denier and 4.3 gram force/denier respectively, the dry and wet elongation is 16.5 percent and 17.5 percent respectively, the Young modulus is 550 kilogram force/millimeter, and the elastic recovery rate (3 percent) is 70 percent; it is characterized by high strength, good toughness, good hygroscopicity, wear resistance, acid and alkali resistance, high wet strength, mildew and moth resistance, etc.; the vinylon fiber is mainly used for making clothes, and can also be used for making various cables, canvases, agricultural windproof and cold-proof gauze, etc.
Since vinylon fiber has excellent moisture absorption performance, vinylon fiber is often used for making clothes worn in summer, but summer weather is hot, ultraviolet intensity is high, and sun protection is also an important thing. However, vinylon fiber has the defects of poor elasticity, poor dyeing property and the like, and the use of the vinylon fiber is limited by the defects, and the defects cannot be changed if the vinylon fiber is used for preparing a fabric by only making yarns from the vinylon fiber.
Disclosure of Invention
The invention aims to provide an ultraviolet-proof and antibacterial fabric and a preparation method thereof, and the ultraviolet-proof and antibacterial fabric with long-acting property is obtained by reasonable organization design and weft insertion sequence, so that the defect that the function of the traditional functional fabric is easy to attenuate is overcome.
The technical scheme of the invention is realized as follows:
the invention provides an ultraviolet-proof and antibacterial fabric which is prepared by mutually and vertically interweaving warps and wefts, wherein the warps are formed by cross combination of warps A and wefts B in a 1:1 relationship, and the wefts are formed by cross combination of wefts A and wefts B in a 1:2 relationship; the mass ratio of the first warp to the second warp is 100: 262-270; the mass ratio of the weft A to the weft B is 166:165-170, the reed number is 12 teeth/cm, the penetration number of each reed is 3 in/teeth, and the blank width is 226 cm; the total warp number is 5356, and the density of the finished product is: the warp density is 325 pieces/10 cm, and the weft density is 252 pieces/10 cm; the weave is a plain weave, and the number of the heald pages is 4 pages; the warp yarns are arranged into a first 2B 1, a first 4B 1, a first 6B 1 and a first 2B 1; the width of the finished product is 207cm, and the weight is 120 g/m;
the first weft adopts antibacterial yarns; the second weft adopts low-twist composite yarn formed by twisting moisture-absorbing and sweat-releasing yarn and fine cotton fiber; the first warp adopts an anti-ultraviolet polyester fiber yarn; the second warp adopts polyester fiber yarns;
the antibacterial yarn is prepared from the following raw materials: polyvinyl alcohol, graphene oxide-silver nano-composite, chitin and plant fiber;
the anti-ultraviolet polyester fiber yarn is prepared from the following raw materials: terylene fiber and modified ZnO-TiO2Nano powder and plant fiber;
the moisture-absorbing and sweat-releasing yarn is prepared from the following raw materials: cotton fiber, vinylon fiber and plant fiber.
As a further improvement of the invention, the titer of the first weft is 500dtex, 700 twists/m, S twist direction; the titer of the weft B is 500dtex, 700 twists/m and Z twist direction; the titer of the first warp is 200dtex, 1700 twist/m and S twist direction; the titer of the second warp is 220dtex, 320 twists/m and Z twist direction.
As a further improvement of the invention, the antibacterial yarn is prepared from the following raw materials in parts by weight: 100-150 parts of polyvinyl alcohol, 5-10 parts of graphene oxide-silver nano compound, 30-50 parts of chitin and 20-40 parts of plant fiber;
