Description

Technical Field

[0001] This invention relates to the field of daily necessities technology, and more specifically, to a high-comfort pillowcase blended fabric. Background Technology

[0002] As living standards improve, people's demands for sleep quality are increasing. Pillowcases, as bedding items that come into direct contact with the skin, have become a key focus for consumers in terms of comfort, breathability, and support. Traditional pillowcase fabrics often use a single material or simple blends, resulting in insufficient breathability, stuffiness, and poor support. Furthermore, the performance of existing pillowcase fabrics in terms of moisture absorption and wicking, antibacterial properties, and odor control needs improvement.

[0003] While some functional pillowcase fabrics exist on the market, most focus on a single property, such as cooling or moisture absorption, lacking optimized designs that consider all aspects of performance. For example, patent application publication number CN208081437U discloses a cooling pillowcase, but its breathability and support are insufficient, failing to meet the comfort requirements for prolonged use. Therefore, there is an urgent need to develop a pillowcase blend fabric that combines high breathability, moisture permeability, cooling sensation, and support. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiments of the present invention provide a high-comfort pillowcase blended fabric. The technical problem to be solved by the present invention is: how to provide a pillowcase blended fabric that combines high breathability, moisture permeability, coolness and support to meet consumers' needs for sleep comfort.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-comfort pillowcase blended fabric, comprising a soft, comfortable, and cool outer fabric layer, a supportive and elastic intermediate spacer layer, and an odor-absorbing inner fabric layer. The outer and inner fabric layers are connected by the intermediate spacer layer, and the outer, intermediate, and inner fabric layers together form a three-dimensional spacer fabric with a multi-layered structure. The thickness of the three-dimensional spacer fabric is set to 1.5-5mm. The three-dimensional spacer fabric has a special three-dimensional porous structure, which is conducive to air flow and heat dissipation. At the same time, its excellent compressibility and resilience are conducive to releasing head pressure and improving durability.

[0006] In a preferred embodiment, the outer fabric layer is made of fiber I, which has excellent moisture absorption and a cooling sensation. The fiber I is composed of one or more blended fibers selected from natural fibers, modal fibers, lyocell fibers, viscose fibers, acrylic fibers, modified polyester fibers, silky cotton fibers, and eucalyptus fibers.

[0007] In a preferred embodiment, the intermediate spacer layer is made of fiber II, which has excellent moisture absorption, moisture wicking and soft support. The fiber II is composed of one or more blended fibers selected from polyurethane fiber, polyester fiber, cotton fiber, bamboo fiber, nylon fiber, merino wool fiber, modal fiber and lyocell fiber.

[0008] In a preferred embodiment, the inner fabric layer is made of fiber III, which can effectively absorb odors. The fiber III is composed of one or more blended fibers selected from wool fiber, bamboo fiber, kapok fiber, activated carbon fiber, seaweed fiber, silver ion fiber, copper ion fiber and polyester fiber.

[0009] In a preferred embodiment, the following production process steps are included:

[0010] S1. Fabric Preparation: Select a multi-layered fabric consisting of an outer layer, a middle interlayer, and an inner layer, woven on an 18-28 gauge circular knitting machine using a weft knitting process. The weight is 300-380 g / m². 2 ;

[0011] S2. Pre-forming: Pre-forming treatment is carried out at a temperature of 180℃-190℃, with the machine speed controlled at 40m / min and overfeeding by 55%.

[0012] S3, singeing: The fabric surface is treated with a single-sided singeing process;

[0013] S4. Refining: Refining is carried out using a mixed solution containing refining agent, H2O2, penetrant and oxygen bath protectant;

[0014] S5. Polishing treatment: Use biological polishing enzymes to treat the fabric at 40℃-50℃ for 30-60 minutes to remove surface fuzz and improve the smoothness of the fabric surface.

[0015] S6. Dyeing: First, use cationic dyes to dye the wool component at 97℃ for 60 minutes, and then use reactive dyes to dye the cotton component at 50℃ for 60 minutes. No color fixing treatment is required after dyeing.

[0016] S7. Finishing: Set the shape at 110-130℃, add hydrophilic softener and acid to adjust the pH;

[0017] S8. Dry fabric: After dyeing, it undergoes dehydration and opening treatment;

[0018] S9. Setting: Final setting is carried out at a temperature of 110℃-130℃, with the setting speed controlled at 30m / min, overfeeding controlled at 50-60%, 3-5% hydrophilic softener added and pH adjusted to 5.5-6.5;

[0019] S10. Check the fabric: Conduct quality inspection on the finished fabric.

[0020] In a preferred embodiment, the fabric in step S1 consists of the following:

[0021] Outer fabric layer: Made of a blend of lyocell and cotton fibers, the synergistic effect of the two materials achieves a comfortable cooling sensation. The circular cross-section and smooth surface of Tencel fibers significantly reduce the coefficient of friction with the skin (about 30% lower than cotton), enabling rapid heat conduction. At the same time, the natural hydrophilicity of cotton fibers supplements the moisture absorption function, forming a composite cooling mechanism of "rapid heat conduction + efficient moisture absorption".

[0022] Intermediate spacer layer: A cross-linked polyester mesh of a certain thickness is used as the main structure to effectively disperse vertical pressure through fiber deformation; at the same time, high-elastic spandex yarn is embedded in the weaving system to provide rapid rebound recovery when external force is removed; this composite design of "rigid skeleton (polyester) + elastic drive (spandex)" not only ensures the uniformity of pressure buffering, but also maintains the long-term shape stability of the structure, thereby achieving dynamic support;

[0023] Inner fabric layer: made of blended yarn of wool and polyester, with wool accounting for 6%-23%.

[0024] In a preferred embodiment, the amount of refining agent used in step S4 is 1-3 g / L, the amount of H2O2 used is 3-5 g / L, and the treatment time is 30-45 minutes.

[0025] In a preferred embodiment, the amount of biopolishing enzyme used in the polishing process of step S5 is 1-3% owf, and the bath ratio is 1:10-1:15.

[0026] In a preferred embodiment, during the dyeing process of step S6, glacial acetic acid is added to adjust the pH to 4-5 when dyeing with cationic dyes; sodium sulfate and soda ash are added as dyeing accelerators when dyeing with reactive dyes.

[0027] The technical effects and advantages of this invention are as follows:

[0028] The fabric of this invention utilizes a multi-layered structure design to create a three-dimensional porous structure, promoting airflow and heat dissipation, and possessing excellent moisture permeability and breathability, ensuring comfort and hygiene during use. The outer layer of the fabric in contact with the skin uses cooling fibers, while the middle interlayer achieves dynamic support and long-term shape stability through a composite design of a rigid skeleton and elastic drive, significantly improving user comfort. The moisture permeability and breathability design of the pillowcase further enhances the user experience, avoiding stuffiness and discomfort. Combined with the synergistic effect of specific fiber materials, it achieves a comprehensive improvement in breathability, moisture permeability, cooling sensation, and support.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] This invention provides, for example Figure 1-5 The pillowcase blended fabric shown comprises a soft, comfortable, and cooling outer fabric layer, a supportive and elastic intermediate spacer layer, and an odor-absorbing inner fabric layer. The outer and inner fabric layers are connected by the intermediate spacer layer, and together they form a three-dimensional spacer fabric with a multi-layered structure. The thickness of the three-dimensional spacer fabric is set at 1.5-5mm. This three-dimensional spacer fabric has a special three-dimensional porous structure that facilitates airflow and heat dissipation. Its excellent compressibility and resilience help release head pressure and improve durability. The manufacturing process includes the following steps:

[0037] S1. Fabric Preparation: Select a multi-layered fabric consisting of an outer layer, a middle interlayer, and an inner layer, woven on an 18-28 gauge weft-knitted circular knitting machine using a weft knitting process. Figure 1-2 It is woven using a weft knitting process involving floating threads, pre-forming loops, forming loops, and tucking loops, with a weight of 300-380 g / m2.

[0038] The fabric is composed of the following:

[0039] Outer fabric layer: Made of a blend of lyocell and cotton fibers, the synergistic effect of the two materials achieves a comfortable cooling sensation. The circular cross-section and smooth surface of Tencel fibers significantly reduce the coefficient of friction with the skin (about 30% lower than cotton), enabling rapid heat conduction. At the same time, the natural hydrophilicity of cotton fibers supplements the moisture absorption function, forming a composite cooling mechanism of "rapid heat conduction + efficient moisture absorption".

[0040] Intermediate spacer layer: A cross-linked polyester mesh of a certain thickness is used as the main structure to effectively disperse vertical pressure through fiber deformation; at the same time, high-elastic spandex yarn is embedded in the weaving system to provide rapid rebound recovery when external force is removed; this composite design of "rigid skeleton (polyester) + elastic drive (spandex)" not only ensures the uniformity of pressure buffering, but also maintains the long-term shape stability of the structure, thereby achieving dynamic support;

[0041] Inner fabric layer: made of blended yarn of wool and polyester, with wool accounting for 6%-23%;

[0042] Specifically, such as Figure 3-4 The wiring structure is used to prepare the fabric by weaving the corresponding fibers to obtain the corresponding blended fabric.

[0043] S2, Pre-setting: Pre-setting process is carried out at 180℃-190℃, with machine speed controlled at 40m / min and overfeed by 55% to ensure fabric dimensional stability.

[0044] S3, singeing: The fabric surface is treated with a single-sided singeing process;

[0045] S4. Refining: Use a refining agent (dosage 1-3g / L) and H2O. 2( Dosage is 3-5g / L ) The mixture of penetrant and oxygen bath protectant is refined for 30-45 minutes.

[0046] S5. Polishing treatment: Use 1-3% owf of biological polishing enzyme to treat at 40℃-50℃ for 30-60 minutes to remove surface fuzz, reduce fuzz friction on the skin, and improve the smoothness of the fabric surface. The solution to fiber bath ratio is 1:10-1:15.

[0047] S6. Dyeing: First, cationic dyes are added with glacial acetic acid to adjust the pH to 4-5, and the wool component is dyed at 97℃ for 60 minutes. Then, reactive dyes are added with sodium sulfate and soda ash as dyeing accelerators and the cotton component is dyed at 50℃ for 60 minutes. No color fixing treatment is required after dyeing. The dyeing compatibility problem between wool and cotton is solved by the step-by-step dyeing steps of cationic and reactive dyes (because wool is not alkali-resistant while cotton requires alkaline conditions).

[0048] S7. Finishing: Set the shape at 110-130℃, add hydrophilic softener and acid to adjust the pH;

[0049] S8. Dry fabric: After dyeing, it undergoes dehydration and opening treatment;

[0050] S9. Setting: Final setting is carried out at a temperature of 110℃-130℃, with the setting speed controlled at 30m / min, overfeeding controlled at 50-60%, 3-5% hydrophilic softener added and pH adjusted to 5.5-6.5;

[0051] S10. Check the fabric: Conduct quality inspection on the finished fabric.

The components of fiber I are one or more blended fibers selected from natural fibers, modal fibers, lyocell fibers, viscose fibers, acrylic fibers, modified polyester fibers, silky cotton fibers, and eucalyptus fibers.

[0053] The intermediate spacer layer is made of fiber II, which has excellent moisture absorption, moisture wicking and soft support. The fiber II component is composed of one or more blended fibers selected from polyurethane fiber, polyester fiber, cotton fiber, bamboo fiber, nylon fiber, merino wool fiber, modal fiber and lyocell fiber.

[0055] Example 1

[0056] A high-comfort pillowcase blended fabric, the pillowcase is made of seven-layer interlayer fabric, and the edges of the pillowcase have zippers or buttons for easy removal and washing. Specific technology is as follows:

[0057] It includes an outer fabric layer, an intermediate spacer layer, and an inner fabric layer;

[0058] The outer fabric layer is made of a 70% silk modal / 30% cotton blend yarn with a yarn count of 50S. It is a moisture-wicking fiber with good skin-friendliness and softness.

[0059] The middle interlayer fabric is made of low-elastic polyester filament fibers (30D / 75D) and spandex fibers (30D). Relying on the capillary channels formed by the yarn arrangement and interlayer structure, it promotes the diffusion and transfer of sweat, thereby improving the pillowcase's sweat-wicking and quick-drying performance. The low-elastic polyester fibers have excellent support, further enhancing the pillowcase's structural stability and comfort. The spandex fibers (30D) in the middle interlayer are set in an interlaced connection manner, giving the pillowcase excellent elastic adjustment function and applicability.

[0060] The inner fabric layer is made of a blend of wool and polyester yarn (40S). The wool fibers contain acidic groups and amino groups, which can provide abundant adsorption sites to effectively absorb volatile components, thereby achieving a natural anti-odor function. In addition, the wool fibers can release the adsorbed odors during washing to ensure the hygiene and long-lasting freshness of the pillowcase.

[0061] The Shichimeiji pillowcase uses a weft knitting process to achieve a tight bond of multiple materials, with a weight of 363g / m². 2 Specifically, such as Figure 5 The outer layer, serving as the main yarn 1 (outer and inner fabric layers), is woven with wool / cotton blended yarn using interlaced floats, forming a honeycomb microporous structure on the surface. The elastic layer, serving as the filler yarn 2, uses spandex as the filler yarn and is woven into the composite fabric. The connecting yarn 4 is set as two polyester yarns interlaced to provide a certain degree of support. The binding yarn 3 is formed by binding the connecting polyester yarn to the spandex. The filler yarn 2, binding yarn 3, and connecting yarn 4 together form an intermediate spacer layer for connecting the outer and inner fabric layers.

[0062] Implementation Case 2

[0063] A high-comfort pillowcase blended fabric, the pillowcase is made of five-layer interlayer fabric, and the edges of the pillowcase have zippers or buttons for easy removal and washing. Specific technology is as follows:

[0065] The middle interlayer is made of polyester fiber (30D / 75D), which is a moisture-wicking fiber that can effectively improve the pillowcase's sweat-wicking performance; the low-elastic polyester fiber has excellent support and elasticity adjustment function, further enhancing the pillowcase's structural stability and comfort.

[0066] The inner fabric layer is made of a blend of wool and polyester fibers (40S). The wool contains acidic groups and amino groups, which can provide abundant adsorption sites and effectively absorb volatile components, thereby achieving a natural anti-odor function. In addition, the wool fibers can release the adsorbed odors during washing, ensuring the hygiene and long-lasting freshness of the pillowcase.

[0067] The Gomeiji pillowcase achieves a tight bond of multiple materials through processes such as hot pressing, adhesive bonding, ultrasonic bonding, or weft knitting, with an overall weight of 300g / m². 2 .

[0072] The middle interlayer uses low-elastic polyester filament fibers (30D / 75D) and spandex fibers (30D). The capillary channels formed by the yarn arrangement and interlayer structure promote the diffusion and transfer of sweat, thereby improving the pillowcase's wicking and quick-drying performance. The low-elastic polyester fibers, acting as connecting yarns, provide excellent support and elasticity adjustment, further enhancing the pillowcase's structural stability and comfort. The spandex fibers (30D) in the middle interlayer, used as filler yarns and interlaced, give the pillowcase excellent elasticity adjustment and a springy feel, further improving its comfort.

[0073] The inner fabric layer is made of a blend of wool and polyester yarn (40S). The wool fibers contain acidic groups and amino groups, which can provide abundant adsorption sites and effectively absorb volatile components, thereby achieving a natural anti-odor function. The wool fibers can release the adsorbed odors during washing to ensure the hygiene and long-lasting freshness of the pillowcase.
