Description

Technical Field

[0001] This invention relates to the field of wig netting technology, and more specifically, to a breathable and reinforced non-adhesive lace netting cap and its preparation method. Background Technology

[0002] Lace mesh caps are a core accessory used to secure wigs and fit the scalp when wearing wigs. As the consumption scenarios for wigs have expanded from performance needs to daily beauty and grooming, the market has placed higher demands on the stability, breathability, and wearing comfort of mesh caps.

[0003] Currently, the mainstream lace mesh caps on the market are mainly divided into two categories: one is ordinary single-layer lace mesh caps, which use a single lace fabric throughout. To ensure support, high-density nylon lace is usually selected. However, these types of mesh caps have poor breathability, and the scalp is prone to sweating and feeling stuffy when worn. Especially in summer or when worn for a long time, they can cause problems such as scalp itching and odor. If low-density lace is used to improve breathability, the fabric has insufficient tensile strength, and the stress areas such as the forehead edge and behind the ears are prone to loosening and deformation, with a service life of only 1 to 2 months.

[0004] Secondly, lace mesh caps with local reinforcement usually use glue to attach double layers of lace for reinforcement. However, long-term contact of glue with the scalp can easily cause allergies, and as the time of use increases, the glue will age and peel off, causing the double layers of lace to slide apart and the reinforcement effect to fail. At the same time, after the glue hardens, it will cause the local lace to harden, causing friction with the scalp when worn, resulting in local redness and discomfort.

[0005] In addition, the reinforcement and ventilation areas of existing mesh caps are mostly straight and rigidly spliced ​​together, with obvious differences in thickness at the splice. When wearing them, the protruding seams will repeatedly rub against the scalp, causing a stinging sensation. Furthermore, the edges of the reinforcement area lack elastic treatment, resulting in poor head circumference fit. People with larger heads will find them too tight, while those with smaller heads will find them prone to shifting and falling off.

[0006] While some improved breathable wig caps attempt to enhance breathability by using perforated fabrics, they lack zoned design to address scalp sweat distribution, only featuring small ventilation holes in specific areas. This results in limited heat dissipation and fails to address the stuffiness issue in key sweat-prone areas such as the forehead and crown. Furthermore, excessive perforation can lead to insufficient overall support, making them unsuitable for heavier wig styles. Therefore, this paper proposes a breathable and reinforced non-adhesive lace wig cap and its manufacturing method. Summary of the Invention

[0007] The purpose of this invention is to address the problems raised in the existing background technology. To achieve the above-mentioned objective, this invention provides the following technical solution: a breathable and reinforced non-adhesive lace mesh cap, comprising a cap body, wherein the cap body is divided into a reinforcement area and a breathable area according to functional partitions: the reinforcement area is located at the forehead edge, the connection point behind the ears, and the top stress concentration area of ​​the cap body, and adopts a double-layer reinforced lace structure; The breathable area is located on the upper middle part of the forehead and the top of the head, corresponding to the scalp where sweating is likely to occur, and is made of hollowed-out breathable lace; the reinforced area and the breathable area are connected by a gradient splicing, and the splicing surface width is 8mm to 12mm.

[0012] As a preferred technical solution of the present invention, the double-layer lace edge of the reinforced area is treated with elastic lace strip; the width of the elastic lace strip is 0.7mm to 0.9mm, the spandex content is 18% to 22%, and the tensile resilience is ≥95%.

[0013] A method for preparing a breathable and reinforced adhesive-free lace mesh cap includes the following steps: S1: Fabric selection and cutting: Select high-tenacity nylon lace with a breaking strength ≥32N / mm as the fabric for the reinforcement area, and select low-density nylon lace with a hollow rate of 38%~42% as the fabric for the breathable area; cut the double-layer lace pieces for the reinforcement area and the lace pieces for the breathable area according to the target head circumference size, and pre-lock the edges with an overlock machine at a density of 3 stitches / cm~4 stitches / cm; S2: Reinforcement Area Shaping Treatment: Align and lay the two layers of reinforcement lace pieces flat, and use a hot-melt shaping device to form hot-melt shaping points with a diameter of 0.9mm to 1.1mm between the two layers of lace, with a spacing of 9mm to 11mm between the shaping points; place the bonded double-layer reinforcement lace pieces in a custom metal mold, and hot-press and shape them for 16s to 19s under the conditions of temperature 125℃ to 135℃ and pressure 0.35MPa to 0.45MPa. S3: Patchwork and stitching: Align the reinforced lace pieces with the breathable lace pieces along the gradient patchwork surface after shaping, and use 60S / 3 polyester core-spun thread to perform flat stitching with a stitch spacing of 1.8mm to 2.2mm, with the stitches hidden in the gaps of the lace texture; use elastic lace strips with a spandex content of 18% to 22% to perform edge binding and stitching along the edge of the reinforced area with a density of 4 stitches / cm to 5 stitches / cm; S4: Overall post-processing: Place the assembled net cap body in a steam fumigation device and fumigate at a temperature of 96℃~99℃ for 6min~7min to eliminate sewing tension; use a soft brush to remove surface dust, check for defects such as lace fraying and loose stitches, and finally obtain the finished net cap.

[0017] Compared with existing technologies, the beneficial effects of this invention are as follows: This breathable and reinforced glue-free lace mesh cap completely solves the pain point of the conflict between breathability and stability in traditional products through functional zone design. The reinforced zone uses double-layer fabric with heat-fused shaping points to achieve strong support. It is not easy to loosen or shift even after repeated removal and pulling, and the stress is evenly distributed over a larger area, greatly reducing the risk of fabric breakage. It is suitable for high-frequency usage scenarios such as long-term wear and frequent wig replacement. The highly perforated fabric in the breathable zone precisely covers the core sweating areas such as the forehead and top of the head, allowing hot and humid air to be quickly expelled and simultaneously introducing cool air from the outside to form a circulation, fundamentally alleviating the problem of scalp stuffiness and sweat accumulation during summer or long-term wear.

[0018] This invention utilizes a glue-free hot-melt setting process to replace traditional adhesive bonding, completely avoiding irritating residues and delamination issues, making it suitable for long-term safe wear by people with sensitive scalps. The seam area employs a gradient, seamless process, eliminating the raised friction points of traditional mesh caps. The elastic edging flexibly adapts to different head circumferences, ensuring a comfortable fit without constricting the scalp or shifting. Reinforced edging effectively prevents lace snagging and unraveling, significantly extending the product's lifespan. Suitable for diverse scenarios such as daily commutes, outdoor activities, and high-temperature environments, it provides stable support for the wig while creating a cool and comfortable wearing experience for the scalp.

[0022] Example 1: A breathable and reinforced non-adhesive lace mesh cap, including a mesh cap body 1, which is divided into a reinforcement area 101 and a breathable area 102 according to functional partitions. The reinforcement area is set at the forehead edge, the connection behind the ears and the top stress concentration area of ​​the mesh cap body, and adopts a double-layer reinforced lace structure. The breathable area is located on the upper middle part of the forehead and the top of the head, where the scalp is prone to sweating, and is made of hollowed-out breathable lace; the reinforced area and the breathable area are connected by a gradient splicing, with the splicing surface width being 8mm to 12mm.

[0023] Double-layer reinforced lace is composed of two layers of high-tenacity nylon lace with the same texture, which are aligned and stacked, and the two layers of lace are locally bonded together by heat-melting shaping points. The diameter of the hot-melt setting point is 0.9mm to 1.1mm, the center-to-center distance between adjacent hot-melt setting points is 9mm to 11mm, the distribution density of the hot-melt setting points is 8 to 10 per cm², and the area of ​​the two layers of lace bonded together accounts for 15% to 20% of the total area of ​​the reinforced area.

[0024] The tensile strength of high-tenacity nylon lace is ≥32N / mm, and the warp and weft density is 28 threads / cm to 32 threads / cm.

[0025] The openwork breathable lace is made of low-density nylon lace, with a diamond-shaped openwork array pattern. The diagonal length of the openwork holes is 2.5mm to 3.5mm, and the openwork rate is 38% to 42%. The warp and weft density of the low-density nylon lace is 16 threads / cm to 20 threads / cm.

[0026] The reinforced area and the breathable area are joined by a flat stitch, with polyester core-spun thread, thread number 60S / 3, and stitch length of 1.8mm to 2.2mm. The stitch is completely hidden in the gaps of the lace texture, and the surface thickness difference at the joint is ≤0.2mm.

[0027] The double-layered lace edge of the reinforced area is edged with elastic lace strips; the width of the elastic lace strips is 0.7mm to 0.9mm, the spandex content is 18% to 22%, and the tensile resilience is ≥95%.

[0028] A method for preparing a breathable and reinforced non-adhesive lace mesh cap includes the following steps: S1: Fabric selection and cutting: Select high-toughness nylon lace with a breaking strength ≥32N / mm as the fabric for the reinforcement area, and select low-density nylon lace with a hollowness rate of 38%~42% as the fabric for the breathable area; cut the double-layer lace pieces for the reinforcement area and the lace pieces for the breathable area according to the target head circumference size, and pre-lock the edges of the cut edges with an overlock machine at a density of 3 stitches / cm~4 stitches / cm; S2: Reinforcement Area Shaping Treatment: Align and lay the two layers of reinforcement lace pieces flat, and use a hot-melt shaping device to form hot-melt shaping points with a diameter of 0.9mm to 1.1mm between the two layers of lace, with a spacing of 9mm to 11mm between the shaping points; place the bonded double-layer reinforcement lace pieces in a custom metal mold, and hot-press and shape them for 16s to 19s under the conditions of temperature 125℃ to 135℃ and pressure 0.35MPa to 0.45MPa. S3: Patchwork and stitching: Align the reinforced lace pieces with the breathable lace pieces along the gradient patchwork surface after shaping, and use 60S / 3 polyester core-spun thread to perform flat stitching with a stitch spacing of 1.8mm to 2.2mm, with the stitches hidden in the gaps of the lace texture; use elastic lace strips with a spandex content of 18% to 22% to perform edge binding and stitching along the edge of the reinforced area with a density of 4 stitches / cm to 5 stitches / cm; S4: Overall post-processing: Place the assembled net cap body in a steam fumigation device and fumigate at a temperature of 96℃~99℃ for 6min~7min to eliminate sewing tension; use a soft brush to remove surface dust, check for defects such as lace fraying and loose stitches, and finally obtain the finished net cap.

[0029] In step S2, the surface roughness Ra of the customized metal mold is ≤0.8μm, and the surface tolerance for conforming to the human head shape is ≤0.5mm.

[0030] In step S4, after steam fumigation, the main body of the net cap is placed on the head mold and allowed to cool naturally for 10 to 15 minutes. The tolerance between the head mold size and the target head circumference is ≤0.3mm.

[0031] In step S1, the cutting allowance of the lace piece in the reinforcement area is 2mm to 3mm, which is used to compensate for the shrinkage during the hot pressing and shaping process.

[0032] The working principle of this breathable and reinforced adhesive-free lace mesh cap is based on the zonal stress characteristics and sweat distribution patterns of the human head. A functional zoning design achieves a balanced wearing performance: the forehead edge, the area behind the ears, and the top of the head are the main stress points when wearing a wig, and are prone to tensile tension during daily removal and head movements. The reinforcement area uses a double-layer high-toughness nylon lace structure, utilizing the high tensile strength of nylon fibers (≥32N / mm) and a warp and weft density of 28-32 threads / cm to distribute external forces across the double-layer fabric, preventing localized breakage and deformation due to concentrated stress. Simultaneously, heat-sealing points covering 15%-20% of the area fix the relative positions of the double-layer lace through localized adhesion, preventing shifting and slippage, further enhancing overall tensile strength, and ensuring the cap's shape remains stable and does not loosen or deform during long-term wear.

[0033] The upper-middle forehead and top of the head are areas prone to sweating. The breathable areas are made of low-density nylon lace with a perforation rate of 38% to 42%, and the diamond-shaped perforation array expands the air circulation channels. When the scalp sweats and dissipates heat, the hot and humid air can be quickly expelled through the perforations, while fresh air from the outside flows in, forming a microcirculation. This reduces the humidity and temperature between the scalp and the cap, reduces stuffiness, and improves wearing comfort.

[0034] The heat-sealing points are evenly distributed between the double layers of lace at a density of 8 to 10 points per cm², with each point having a diameter of 0.9 mm to 1.1 mm. When the reinforced area is subjected to tensile force, the points can transfer the local tension to both layers of lace, preventing the single layer from deforming independently. Simultaneously, the adhesive strength of the points can resist the peeling force between the two layers, maintaining the structural integrity. Combined with the 0.9 mm to 1.1 mm spacing between the points, this ensures both reinforcement and preserves the original flexibility of the lace fabric, preventing localized hardening and irritation to the scalp.

[0035] The reinforced and breathable areas feature a gradient stitching design with a width of 8mm to 12mm, rather than a rigid straight stitching. This transition area allows for a gradual change in fabric density, reducing localized stress concentration caused by sudden changes in force and preventing the risk of tearing at the seams. Simultaneously, the concealed flat seam process ensures a thickness difference of ≤0.2mm at the seams, guaranteeing a smooth surface and eliminating any raised friction during wear, thus enhancing comfort and fit.

[0036] The reinforced area is edged with elastic lace strips containing 18%–22% spandex. These elastic lace strips have a ≥95% tensile resilience, allowing them to adapt to different head circumferences, conforming to the head's curves and preventing the net from being too tight and compressing the scalp, or too loose and shifting. The edge binding also protects the lace edges, preventing lace fibers from unraveling and enhancing the net's durability.

[0037] Abandoning traditional glue bonding methods, this product utilizes heat-melt setting to achieve partial adhesion of the double-layer lace. Heat-melt setting involves the nylon fabric itself melting and solidifying upon heating, eliminating the need for external adhesives and preventing delamination caused by adhesive aging and failure. It also reduces contact with irritating substances on the scalp, enhancing safety. The reinforced area after heat-pressing is then steam-fumigated and cooled using a head mold to relieve stress, resulting in a stable setting that is resistant to deformation over long-term use.

[0038] The working process of the breathable and reinforced non-adhesive lace mesh cap: Step 1: Fitting Stage: When wearing the cap, the reinforced area should be aligned with the edge of the forehead, behind the ears, and the pressure points on the top of the head. The elastic lace strips (18%–22% spandex content) at the edge of the reinforced area will first contact the scalp, relying on their own elasticity to conform to the curve of the head shape, automatically adapting to different head sizes, quickly achieving initial positioning, and preventing the cap from slipping or shifting.

[0039] Once the wig is fully in place, the double-layered high-tenacity nylon lace (tensile strength ≥32N / mm) in the reinforced area absorbs the pulling force generated by the movement of the wig and head. The double-layered structure distributes the tension over a larger area of ​​the fabric, and with the fixation of the heat-fused shaping points, the stress is evenly distributed throughout the reinforced area, preventing localized tightness or breakage of the lace due to stress concentration. This also ensures the wig fits snugly against the scalp without any noticeable gaps.

[0040] Step Two, Daily Use Stage: When putting on and taking off the wig daily, and when moving the head, the reinforced area uses double-layer fabric and heat-fused shaping points to resist external forces. When subjected to tensile force, the high warp and weft density of the double-layer lace (28 threads / cm to 32 threads / cm) restricts fabric deformation and prevents the mesh cap from being stretched loose. The hot-melt setting points have a diameter of 0.9mm to 1.1mm and a spacing of 9mm to 11mm, which can lock the relative position of the two layers of lace, prevent the two layers of lace from slipping or misaligning, and ensure the long-term stability of the shape of the net cap. After 1000 simulated wearing and tensile tests, the deformation of the reinforced area is ≤3% of the initial length, and the tensile deformation rate is ≥95%.

[0041] When the scalp sweats, the diamond-shaped openwork lace in the breathable area comes into play: The humid and hot air generated by the scalp is quickly dissipated to the outside through the lace mesh with a 38% to 42% openness ratio; Low-temperature air from outside flows into the gap between the scalp and the mesh cap through the perforations, creating a micro-circulation of air, reducing local temperature and humidity, decreasing sweat buildup, keeping the scalp dry, and avoiding a stuffy and sticky feeling.

[0042] Step 3, Dynamic Adaptation Stage: When the head makes large movements (such as looking down or turning the head), the elastic lace strips at the edges of the reinforced area adapt to the changes in head shape and stretch accordingly. The stretching rebound rate is ≥95%, and the head immediately returns to its initial state after the movement ends. It always fits the scalp and will not curl or shift due to pulling. The gradient transition design at the splicing reduces sudden changes in stress between areas and prevents the spliced ​​fabric from being torn.

[0043] Because the seams are hidden in the gaps of the lace texture, the thickness difference at the seams is ≤0.2mm. When the scalp comes into contact with the mesh cap during wear, there are no obvious raised friction points on the surface. The smoothness of the double-layer reinforced lace and the hollowed-out breathable lace fabric, combined with the flat structure after shaping, avoids discomfort such as itching and friction pain when wearing, and is suitable for long-term wear.

[0044] IV. Durability Maintenance Stage: The glue-free adhesive structure achieved through heat-melt setting avoids the aging and delamination problems of traditional adhesive bonding. In daily use, the heat-melt setting points maintain stable adhesion strength, and the double-layer lace is not prone to delamination; the elastic lace strips at the edges of the reinforced area maintain the tightness of the binding through elastic tension, preventing the lace fibers from unraveling; the stress of the mesh cap structure, after steam setting and head mold cooling, is eliminated, and even with long-term storage or repeated wear, it is not prone to deformation or hardening, extending the product's lifespan.

[0045] Example 2: In this example, the breathable and reinforced glue-free lace mesh cap is adapted to a standard head circumference of 58cm. The specific configuration is as follows: Functional zoning: The reinforced area covers the edge of the forehead, the back of the ears on both sides, and the stress point on the top of the head, with a total area of ​​approximately 220cm²; the breathable area is located in the upper middle part of the forehead and the top of the head, with an area of ​​approximately 350cm². The two are connected by a 10mm wide gradient splicing strip.

[0046] Fabric selection: The reinforced area uses high-tenacity nylon lace with a breaking strength of 34N / mm and a warp and weft density of 30 threads / cm, with a total thickness of about 0.5mm after double-layer stacking; the breathable area uses low-density nylon lace with a hollow rate of 40% and a warp and weft density of 18 threads / cm, with a diagonal length of 3mm for the hollow diamond holes.

[0047] Hot-melt shaping design: The diameter of the hot-melt shaping point between the two layers of reinforcing lace is 1mm, the center spacing is 10mm, the distribution density is 9 points / cm², and the bonding area accounts for 18% of the total area of ​​the reinforcing area.

[0048] Details of the stitching: 60S / 3 polyester core-spun thread is used for flat stitching with a stitch spacing of 2mm, and the thickness difference at the stitching point is 0.15mm; the edge of the reinforced area is decorated with a 0.8mm wide elastic lace strip with a spandex content of 20%.

[0049] Manufacturing process: Fabric cutting: Cut the double-layer lace piece for the reinforcement area and the lace piece for the breathable area according to the 58cm head circumference size, leaving a 2.5mm cutting allowance, and pre-lock the edges with a density of 3.5 stitches / cm.

[0050] Reinforcement area shaping: Two layers of reinforcing lace are aligned and laid flat. After the shaping points are bonded by hot melting equipment, they are placed in a custom head shape mold with a surface roughness Ra of 0.6μm. They are then hot-pressed and shaped for 17.5s at 130℃ and 0.4MPa pressure. After shaping, the reserved allowance is cut off.

[0051] Patchwork stitching: The reinforced area and the breathable area are stitched flush along the gradient patchwork surface, and the stitches are completely hidden within the lace texture; the elastic lace strip is bound along the edge of the reinforced area with a density of 4.5 stitches / cm.

[0052] Post-processing: The net cap is placed in 98℃ steam for 6.5 minutes, then fitted with a head mold with a tolerance of 0.25mm and allowed to cool naturally for 12 minutes. Surface dust is removed and quality inspection is performed to obtain the finished net cap.

[0053] Implementation results: The mesh cap can withstand 80N of tension without loosening or deforming. The air circulation rate in the breathable area is 42% higher than that of ordinary mesh caps. The splicing area is smooth to the touch without any protrusions. The elastic edging can accommodate head circumferences of 55cm to 60cm. No loosening or damage has occurred after 3 months of daily wear. It is suitable for long-term wear of wigs and the needs of high-temperature summer scenarios.

8. The method for preparing a breathable and reinforced non-adhesive lace mesh cap according to claim 7, characterized in that, In step S2, the surface roughness Ra of the customized metal mold is ≤0.8μm, and the surface tolerance for conforming to the human head shape is ≤0.5mm.

9. The method for preparing a breathable and reinforced non-adhesive lace mesh cap according to claim 7, characterized in that, In step S4, after steam fumigation, the main body of the net cap is placed on the head mold and allowed to cool naturally for 10 to 15 minutes. The tolerance between the head mold size and the target head circumference is ≤0.3mm.

10. The method for preparing a breathable and reinforced non-adhesive lace mesh cap according to claim 7, characterized in that, In step S1, the cutting allowance of the lace piece in the reinforcement area is 2mm to 3mm, which is used to compensate for the shrinkage during the hot pressing and shaping process.
