Description

Technical Field

[0001] This invention relates to the field of knitted fabric technology, specifically to a multifunctional knitted fabric. Background Technology

[0002] Summer's strong ultraviolet rays damage skin health, and increased sweating means that while cotton products absorb sweat, they can stick to the skin, causing discomfort and allowing bacteria to thrive, posing a threat to skin health. Fabrics that simultaneously offer UV protection, antibacterial properties, and moisture-wicking quick-drying capabilities have a significant market potential.

[0003] Generally, UV-protective materials typically incorporate inorganic titanium dioxide or zinc oxide ultrafine or nanoparticles during the melt spinning stage to achieve their UV protection function. However, firstly, ultrafine powders can only scatter and reflect UV rays, not provide effective UV protection. Secondly, while nanoparticles can absorb UV rays, the effect is limited. Moreover, the greatest risk lies in their potential harm to the human body. Because nanoparticles are extremely fine (tens of nanometers), they can easily penetrate the body, causing potentially serious damage. Increasing the particle size would reduce absorption, limiting their effectiveness to scattering. Summary of the Invention

[0004] To address the above problems, the present invention provides a multifunctional knitted fabric that simultaneously possesses UV protection, antibacterial properties, and moisture-wicking and quick-drying functions.

[0005] The technical solution is as follows: a multifunctional knitted fabric, comprising an outer UV-resistant layer, characterized in that it further comprises an inner antibacterial, moisture-wicking and quick-drying layer, wherein the outer UV-resistant layer and the inner antibacterial, moisture-wicking and quick-drying layer are woven from nylon-covered polyester core structure filaments and other polyester filaments, wherein zinc oxide particles with a diameter of 300-500nm are added to the nylon-covered polyester core structure filaments, and the inner antibacterial, moisture-wicking and quick-drying layer is knitted to form a mesh for accumulating sweat and moisture-wicking grooves for wicking away moisture.

[0006] Its further features are:

[0007] The outer UV-resistant layer and the inner antibacterial, moisture-wicking, and quick-drying layer are formed by knitting with a two-needle-track upper needle plate and a three-needle-track lower needle cylinder, with 5 ribs and 18 rows forming one cycle. Specifically, in the 1st and 2nd ribs, rows 1, 3, 5, 8, 10, 12, 14, and 17 are knit stitches forming loops, while rows 2, 4, 6, 7, 9, 11, 13, 15, 16, and 18 are knit stitches forming loops. In the 3rd rib, rows 1, 3, 5, 7, 8, 10, 12, 14, 16, and 17 are knit stitches forming loops, while rows 2, 4, 6, 9, 11, 13, 15, and 18 are knit stitches forming loops. In the 4th rib, rows 1, 2, 3, 4, 5, and 18 are knit stitches forming loops, while rows 6, 9, 11, 13, 15, and 16 are knit stitches forming loops. Rows 7, 8, 10, 12, 14, and 17 are knit floats; in the 5th warp, rows 1, 3, 5, 8, 16, and 17 are knit floats, rows 2, 4, 6, 7, 15, and 18 are knit loops, and rows 9, 10, 11, 12, 13, and 14 are knit loops. Rows 1, 3, 5, 8, 10, 12, 14, and 17 are nylon-covered polyester core-sheath filaments with a D / F value of 1-1.5; rows 2, 4, 9, 11, 13, and 18 are nylon-covered polyester core-sheath filaments with a D / F value of 2-2.5; and rows 6, 7, 15, and 16 are polyester filaments with a D / F value of 2-2.5. The D value of the nylon-covered polyester core-sheath filament is 1.5-2 times that of the polyester filament. Rows 7 and 16 are 5.8 cm long. The length of each row is 12.5 cm / 50 stitches to 13 cm / 50 stitches, while the length of each row is 11.5 cm / 50 stitches to 12 cm / 50 stitches.

[0008] The outer layer of the nylon-coated polyester core structure filament is nylon, and the core layer is polyester, with a mass ratio of 25~50:50~75 between the inner and outer layers.

[0009] The fabric undergoes finishing processes, which include: seam allowance, dyeing, dehydration, slitting, and final shaping.

[0010] Beneficial effects: Due to the addition of zinc oxide particles with a diameter of 300-500nm to the filaments in the nylon-polyester core structure, and the two-layer fabric structure, ultraviolet rays can still be scattered and reflected even with relatively large nanoparticles, while also possessing antibacterial properties. Furthermore, through a special weaving process, a fine mesh is formed in the inner layer of the fabric, creating a sweat-collecting effect, and natural moisture-wicking grooves are formed in the elongated sections of the loops, wicking away the collected sweat for quick drying. This allows the fabric to simultaneously possess UV protection, antibacterial properties, and moisture-wicking quick-drying functions. Attached Figure Description

[0013] like Figure 1 The multifunctional knitted fabric shown includes an outer UV-resistant layer 1 and an inner antibacterial, moisture-wicking, and quick-drying layer 2. The outer UV-resistant layer 1 and the inner antibacterial, moisture-wicking, and quick-drying layer 2 are interwoven from nylon-covered polyester core-structure filaments and other polyester filaments. The outer layer of the nylon-covered polyester core-structure filaments is nylon, and the core layer is polyester. The mass ratio of the inner and outer layers is 25~50:50~75. Zinc oxide particles with a diameter of 300-500nm are added to the nylon-covered polyester core-structure filaments. The inner antibacterial, moisture-wicking, and quick-drying layer 2 is knitted to form a mesh for accumulating sweat and moisture-wicking grooves for wicking away moisture. The fabric is processed through finishing steps: seam allowance - dyeing - dehydration - slitting - finishing.

[0014] Specifically, such as Figure 2 As shown, the outer UV-resistant layer 1 and the inner antibacterial, moisture-wicking, and quick-drying layer 2 are formed by knitting with a two-needle-track upper needle plate and a three-needle-track lower needle cylinder, with 5 ribs and 18 rows forming one cycle. In the 1st and 2nd ribs, rows 1, 3, 5, 8, 10, 12, 14, and 17 are purl stitches, and rows 2, 4, 6, 7, 9, 11, 13, 15, 16, and 18 are purl floats. In the third column, rows 1, 3, 5, 7, 8, 10, 12, 14, 16, and 17 are knit stitches on a floating thread, while rows 2, 4, 6, 9, 11, 13, 15, and 18 are knit stitches forming a circle. In the fourth column, rows 1, 2, 3, 4, 5, and 18 are knit stitches forming a circle, while rows 6, 9, 11, 13, 15, and 16 are knit stitches forming a circle, and rows 7, 8, 10, 12, and 17 are knit stitches forming a circle. 4. Rows 17 are knit floats; in the 5th warp, rows 1, 3, 5, 8, 16, and 17 are knit floats, rows 2, 4, 6, 7, 15, and 18 are knit loops, and rows 9, 10, 11, 12, 13, and 14 are knit tucks. Rows 1, 3, 5, 8, 10, 12, 14, and 17 are 75D / 72F nylon-covered polyester core-sheath structure filaments. D value refers to the denier number of the yarn, and F value is the number of single filaments. Rows 2, 4, 9, 11, 13, and 18 are 75D / 36F nylon-covered polyester core-sheath structure filaments, and rows 6, 7, 15, and 16 are 50D / 24F polyester filaments. The D value of the nylon-covered polyester core-sheath structure filament is 1.5-2 times that of the polyester filament. The yarn length (in a 50-gauge fabric) of rows 7 and 16 is 5.8. The stitch length is 12.5 cm / 50 stitches for routes 1, 3, 5, 10, 12, and 14, and 11.8 cm / 50 stitches for other routes.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
