Description

Technical Field

[0001] This utility model belongs to the field of textile technology, specifically a knitted warp-knitted fabric with breathability, sun protection, and a lightweight, cool feel. Background Technology

[0002] With global warming and rising living standards, consumers are increasingly demanding greater comfort and functionality in clothing. In the high temperatures of summer, people desire breathable, sun-protective, lightweight fabrics with a cooling effect. Currently, most sun-protective and cooling fabrics on the market achieve this by adding cooling fibers or using UV-resistant finishing techniques.

[0003] For example, Chinese patent application CN118257025A discloses a breathable sun-protective fabric and its preparation method. It comprises the following raw materials in parts by weight: 30-50 parts natural fiber, 25-45 parts polyester, 35-55 parts spandex, 8-12 parts filler, 5-10 parts sunscreen agent, 1-3 parts coupling agent, 1-3 parts polyamino acid, and 1-3 parts antibacterial agent. The breathable sun-protective fabric of this invention uses a composite blend of natural and chemical fibers, enhancing the material's breathability while maintaining its mechanical properties and acid and alkali resistance. The combined use of sisal and silk fibers enhances the material's breathability, the combination of maifanite powder and periclase powder improves its mechanical properties, and the combination of octocrylene and octyl methoxycinnamate improves its sun protection performance. For example, Chinese patent application CN118390220A discloses a nylon-polyester blended woven sun protection fabric. In its first embodiment, the fabric has a sun protection UPF value of 150+, but its breathability is only 48mm / s, making it difficult to balance various performance aspects.

[0004] However, these methods have problems such as high cost and limited breathability. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention provides a knitted warp-knitted fabric that is breathable, sun-protective, lightweight, and cool to the touch.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A breathable, sun-protective, lightweight, and cool-feeling knitted warp-knitted fabric includes a warp-knitted fabric body. The fabric body comprises non-elastic yarns Y1, Y2, and elastic yarns Y3. The non-elastic yarns Y1 and Y2 are woven to form the surface layer of the fabric body, and the elastic yarns Y3 are woven to form the bottom layer. The non-elastic yarns Y1 form at least one warp-knitted chain structure region A1 and one warp-flat structure region B1 in the warp direction of the fabric body. The non-elastic yarns Y2 form at least one warp-flat structure region B2 in the warp direction. The warp-knitted chain structure region A1 forms a microporous structure on the fabric body. The elastic yarns Y3 connect with the warp-knitted chain structure region A1, causing the microporous structures to converge and form gaps. The ratio of the total area Sa of the warp-knitted chain structure regions A1 and A2 to the total area S of the warp-knitted chain structure regions A1, A2, B1, and B2 satisfies 0. <Sa / S≤3 / 17。

[0008] As a further improvement, the non-elastic yarn Y2 forms at least one warp braided structure region A2 in the warp direction, which forms a structure with micropores on the fabric body.

[0009] As a further improvement, the number of coils M1 in the warp braided structure region A1 and the number of coils N1 in the warp flat structure region B1 are 0. <M1 / N1≤1。

[0010] As a further improvement, the number of coils M2 in the warp braided structure region A2 and the number of coils N2 in the warp flat structure region B2 are 0. <M2 / N2≤1。

[0011] As a further improvement, the ratio of the number of coils N1 in the warp-flat structure region B1 to the number of coils N2 in the warp-flat structure region B2 is: 0 <N1 / N2≤1。

[0012] As a further improvement, the non-elastic yarn Y1 and the non-elastic yarn Y2 are selected as FDY spinning structure or DTY spinning structure of filament nylon, and the elastic yarn Y3 is a composite elastic yarn structure.

[0013] As a further improvement, the elastic yarn Y3 adopts a full-weave structure, and is woven using a warp plain weave structure, a warp satin weave structure, a double warp weave structure, or a weft-inserted structure.

[0014] As a further improvement, the knitting density of the fabric body is between 30 and 60 per centimeter.

[0015] As a further improvement, the weight of the fabric body is 150-190 g / m². 2 .

[0016] Compared with the prior art, the present invention has the following beneficial technical effects:

[0017] Through a combination of specific warp-knitting and warp-flat structures, the bottom elastic yarn Y3, through mechanical constraint, causes the micropores in the surface layer to converge, forming sub-millimeter gaps. This adjustable micropore structure achieves a balance between breathability and UV transmittance. This structural design effectively resolves the contradiction between breathability and UV protection in traditional sunscreen materials. By adjusting the micropore structure ratio, it can meet the UV protection needs of different application scenarios, achieving excellent sun protection while maintaining good breathability. Furthermore, its three-dimensional structure between the top and bottom layers increases airflow, enhancing the fabric's cooling effect and keeping the wearer comfortable in high-temperature environments, combining breathability, sun protection, and a lightweight, cooling feel.

[0024] Example 1

[0025] like Figure 1-3 As shown, a breathable, sun-protective, lightweight, and cool-feeling knitted warp-knitted fabric includes a warp-knitted fabric body. The fabric body comprises non-elastic yarns Y1, Y2, and elastic yarn Y3. The non-elastic yarns Y1 and Y2 are woven to form the surface layer of the fabric body, while the elastic yarn Y3 is woven to form the bottom layer. The non-elastic yarn Y1 forms at least one warp-knitted chain structure region A1 and one warp-flat structure region B1 in the warp direction of the fabric body. The non-elastic yarn Y2 forms at least one warp-flat structure region B2 in the warp direction. The warp-knitted chain structure region A1 forms a structure with micropores on the fabric body. The elastic yarn Y3 connects to the warp-knitted chain structure region A1 to form a mechanical constraint, causing the micropores to converge and form gaps. These gaps are sub-millimeter level. Sub-millimeter level is typically between 0.1 mm and 0.001 mm; in this embodiment, 0.1 mm or 0.05 mm can be selected.

[0026] The warp-linked chain structure area refers to a longitudinal weaving pattern where yarns continuously form loops. This can be achieved using open or closed chain weaving techniques. This structure forms vertically arranged loop columns on the fabric surface, creating stable microporous channels. The warp-plain structure area refers to a weaving pattern where yarns alternately form loops between adjacent warp rows. This can be achieved using single-combed warp-plain or modified warp-plain weave structures. This structure forms a laterally extended loop structure. The elastic yarn-connected chain structure area refers to the placement of elastic material at the sinker arc position of the chain loops. For example, using a weft insertion method to embed elastic yarn into the loop structure formed by non-elastic yarns, utilizing the recoil force of the elastic material to change the loop spacing.

[0027] Specifically, the non-elastic yarn Y1 forms a longitudinally stable porous matrix through a braided structure, while the warp-flat structure provides lateral stretchability. When the elastic yarn Y3 is stretched by an external force, the loop spacing in the braided structure area increases, forming micropores; after the external force disappears, the elastic yarn retracts, causing the edges of the micropores to converge, forming oriented breathable gaps. This structural design allows the fabric to maintain the dense surface required for sun protection when static, and during dynamic wear, pore expansion is triggered by body movement, achieving adaptive adjustment of breathability, i.e., the micropore ratio is adjustable.

[0028] Compared to existing technologies, which rely on fiber modification or coating treatments for sun protection fabrics, this solution achieves functional integration through innovative weaving structures. Chemical auxiliaries in traditional blended fabrics are easily washed away and become ineffective, while this solution utilizes the pores created by its physical structure to maintain a long-lasting balance between sun protection and breathability. This solution achieves its function through a single-layer warp-knitted structure, reducing the weight burden from layered materials and contributing to a lighter, thinner profile. Excellent breathability also enhances the cooling sensation.

[0029] While ensuring sun protection performance, the fabric significantly improves breathability. It automatically adjusts the opening and closing of pores during limb movement, achieving a synergistic effect of static sun protection and dynamic breathability. The combination of elastic and non-elastic yarns in the weaving process gives the fabric both structural stability and shape adaptability, overcoming the shortcomings of traditional sun protection fabrics that are heavy and stuffy, resulting in a lightweight and functional fabric with a continuous cooling sensation.

[0030] Example 2

[0031] refer to Figure 1-3As shown, a breathable, sun-protective, lightweight, and cooling knitted warp-knitted fabric includes a warp-knitted fabric body. The fabric body comprises non-elastic yarns Y1, Y2, and elastic yarn Y3. The non-elastic yarns Y1 and Y2 are woven to form the surface layer of the fabric body, while the elastic yarn Y3 is woven to form the bottom layer. The non-elastic yarn Y1 forms at least one warp-knitted chain structure region A1 and one warp-flat structure region B1 in the warp direction of the fabric body. The non-elastic yarn Y2 forms at least one warp-flat structure region B2 and at least one warp-knitted chain structure region A2 in the warp direction. The warp-knitted chain structure regions A1 and A2 form a microporous structure on the fabric body. The elastic yarn Y3 connects with the warp-knitted chain structure region A1, creating a mechanical constraint that causes the micropores to converge and form gaps. The surface layer forms a three-dimensional structure, enhancing the fabric's cooling effect and keeping the wearer comfortable in high-temperature environments.

[0032] The total area Sa of the warp braided structure region A1 and the warp braided structure region A2, together with the warp braided structure region A1, the warp braided structure region A2, the warp flat structure region B1, and the warp braided structure region B2, are all related to the warp braided structure region A1, the warp braided structure region A2, the warp flat structure region B1, and the warp braided structure region B2.

[0033] The Sa / S ratio controls the distribution relationship between the braided chain structure and the warp flat structure. By limiting the coverage of the braided chain structure in the overall structure, the micropore distribution density and fabric support performance are balanced.

[0034] Specifically, the warp-knitted structure regions A1 and A2 are arranged alternately along the warp direction to form a discretely distributed group of micropores, while the warp-flat structure regions B1 and B2 serve as connecting and supporting areas, filling the spaces between the knitted structures. When the Sa / S ratio is limited to within 3 / 17, the number of micropores in the knitted structure is controlled to ensure breathability while preventing the fabric structure from becoming loose. The continuous loops of the flat structure maintain the fabric's resistance to deformation. Within this limited area ratio, both the basic support performance of the fabric and lightweight and breathable properties are ensured.

[0035] Through the above technical solution, this application achieves an optimized match between the coverage density of sun protection fibers and the number of breathable channels. The discrete distribution pattern of the braided structure effectively blocks the direct path of ultraviolet rays, while the continuous coil network of the warp-flat structure provides a stable supporting substrate for the sun protection functional layer.

[0036] Example 3

[0037] refer to Figure 1-3As shown, the number of coils M1 in the warp chain stitch structure area A1, the number of coils N1 in the warp plain stitch structure area B1, 0 < M1 / N1 ≤ 1; the number of coils M2 in the warp chain stitch structure area A2, the number of coils N2 in the warp plain stitch structure area B2, 0 < M2 / N2 ≤ 1; the ratio relationship between the number of coils N1 in the warp plain stitch structure area B1 and the number of coils N2 in the warp plain stitch area B2: 0 < N1 / N2 ≤ 1.

[0038] Among them, the number of coils M1 refers to the number of longitudinal continuous coils formed in the warp chain stitch structure area A1 per unit area, which can be specifically realized by adjusting the number of comb bar lateral displacements or the warp feeding amount. This value is directly related to the density of the microporous structure. The number of coils N1 refers to the number of horizontally extended coils formed in the warp plain stitch structure area B1 per unit area, providing the lateral extensibility and structural stability of the fabric. The ratio of M1 / N1 controls the coil distribution ratio between the chain stitch structure and the warp plain stitch structure, so as to achieve a dynamic balance between the air permeability of the microporous area and the support of the warp plain stitch area.

[0039] Specifically, when the ratio of the number of coils M1 in the warp chain stitch structure area A1 to the number of coils N1 in the warp plain stitch structure area B1 is controlled within the range of 0 to 1, the coil density in the warp plain stitch structure area B1 is always not lower than that in the chain stitch structure area A1. This enables the micropores formed by the chain stitch structure to remain open, and at the same time, the warp plain stitch structure area B1 provides sufficient lateral traction force through higher density coils to prevent the elastic yarn Y3 from overcontracting and causing the micropores to close. For example, during the knitting process, the comb bar lateral displacement mode can be changed so that after every three longitudinal rows are knitted in the warp chain stitch structure area A1, a knitting unit of the warp plain stitch structure area B1 is inserted.

[0040] For example, by making the ratio of M2 / N2 between 0 and 1, the balance between the micropore density and the support strength can be adjusted. When M2 / N2 is close to 1, the proportion of the chain stitch structure area increases, the micropores are more widely distributed, and the air permeability is improved; when M2 / N2 approaches 0, the proportion of the warp plain stitch structure area increases, and the lateral stability is enhanced. The elastic yarn Y3 is connected to the warp chain stitch structure area A2, so that the micropores gather to form gaps under the elastic action, and at the same time, it prevents the fabric from becoming loose due to excessive stretching.

[0041] N1 is the total number of coils of B1 and N2 is the total number of coils of B2. When the ratio of N^1 / N^2 is set to 0.5, due to the longitudinal knitting characteristics of the warp knitted coils, the yarn gaps at the connection of A1 in B1 are more evenly distributed, and at the same time, the dense structures of B1 and B2 support the micropores to remain in a gathered state.

[0042] Compared to existing technologies, current sun-protective fabrics mostly employ uniformly distributed plain or satin weave structures without controlling the ratio of loop counts in the braided and plain warp structures, resulting in a difficulty in balancing breathability and structural strength. This solution, by limiting the M1 / N1 ratio, allows the fabric to maintain its microporous breathability while the high-density loops in the plain warp structure effectively disperse external forces, preventing fabric deformation caused by the shrinkage of elastic yarns.

[0043] This application, while ensuring the effective formation of the microporous structure, enables the warp-flat structure region to exert a lateral restraint effect on the elastic yarn, preventing the micropores from failing to close due to repeated stretching during wear, while maintaining the overall dimensional stability of the fabric. This proportional control allows the warp-knitted fabric to achieve breathability and sun protection through the chain knitting structure, while maintaining the necessary mechanical properties through the warp-flat structure.

[0044] This application achieves a balance between sun protection and breathability by utilizing the inherent differences in the yarn's weaving structure without adding additional coatings or auxiliaries. The lower loop density of the warp-knitted structure region A1 creates more micropores to enhance airflow, while the higher density structure of the warp-knitted structure region A2 maintains the closure of the micropores through the tension of the elastic yarn, preventing ultraviolet rays from penetrating.

[0045] Furthermore, the non-elastic yarn Y1 and non-elastic yarn Y2 are selected as FDY or DTY spinning structures of filament nylon, and the elastic yarn Y3 is a composite elastic yarn structure. The elastic yarn Y3 adopts a full-weave structure: warp plain weave, warp satin weave, double warp weave, or weft-inserted weave.

[0046] The knitting density of the fabric body is between 30 and 60 per centimeter.

[0047] Knitting density refers to the number of loops formed by yarn per unit length. It can be achieved by adjusting the warp feed rate or needle pitch of the warp knitting machine. This parameter directly affects the porosity and tightness of the fabric. A density range of 30-60 per centimeter can balance breathability and structural stability. High-density areas can reduce ultraviolet penetration, while low-density areas create breathable channels.

[0048] Specifically, in warp knitting, by controlling the arrangement density of the guide needles and the warp feed speed, the yarn forms a knitting structure of 30 to 60 loops per centimeter in the warp direction. When the knitting density is within this range, the interlacing area of ​​the inelastic and elastic yarns can form a uniformly distributed microporous structure, while ensuring the bonding strength between the warp chain structure and the warp flat structure. For example, when using a double-needle bed warp knitting machine, the elastic yarn can be gathered into micropores while maintaining the overall extensibility of the fabric by adjusting the warp feed speed and warp tension.

[0049] Compared to existing technologies, current sun-protective fabrics often employ high-density weaving to enhance UV blocking efficiency, such as a dense structure with over 60 loops per centimeter, resulting in significantly reduced breathability. This solution, however, limits the upper and lower limits of knitting density, preventing excessive compression of the micropores formed in the warp-knitted areas, thus maintaining sun protection performance while ensuring efficient airflow.

[0050] Through the above technical solution, this application can simultaneously achieve sun protection and breathability in high-temperature summer environments, avoiding the stuffiness caused by excessive density, while preventing the structural looseness caused by excessively low density, so that the fabric can balance protection and wearing comfort during outdoor activities.

[0051] The fabric itself has a weight of 150-190 g / m². 2 To ensure thinness and lightness.

[0052] When the weight is below 150g / m2, the sun protection performance may be insufficient due to excessive yarn gaps; while when it is above 190g / m2, the breathability may be affected by excessive yarn density. This range was selected to meet the sun protection requirements while maintaining air circulation through the micropores of the warp-knitted structure, thus balancing sun protection and cooling functions.
