Description

Technical Field

[0001] This invention relates to the field of knitted fabrics, and more specifically, to a collagen-infused, antibacterial, deodorizing, and comfortable knitted fabric. Background Technology

[0002] Traditional knitted fabrics are prone to bacterial growth and odor during daily wear, affecting the wearer's comfort. Although there are some antibacterial and deodorizing fabrics on the market, their effects are not long-lasting and often use chemical methods, which may have negative effects on the skin and the environment. Furthermore, some fabrics are prone to problems such as poor moisture absorption, poor breathability, and poor comfort during long-term wear, failing to meet consumer needs.

[0003] Therefore, developing a fabric that is both environmentally friendly and has antibacterial and deodorizing functions has become a pressing problem for the industry.

[0004] In view of this, the present invention is hereby proposed. Summary of the Invention

[0005] The purpose of this invention is to propose a collagen-based antibacterial, deodorizing, and comfortable knitted fabric to address the shortcomings of existing antibacterial and deodorizing fabrics, which have limited effectiveness and often employ chemical methods that may have negative impacts on the skin and environment. Furthermore, some fabrics are prone to problems such as poor moisture absorption, poor breathability, and poor comfort during long-term wear.

[0006] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0007] A collagen-modified, antibacterial, deodorizing, and comfortable knitted fabric, comprising a first yarn and a second yarn, wherein the first yarn is a blend of collagen-modified viscose fiber and modal fiber, and the second yarn is spandex.

[0008] Furthermore, the weight percentage of the first yarn is 94-96%, and the weight percentage of the second yarn is 4-6%.

[0009] Furthermore, in the first yarn, the blending mass ratio of collagen-modified viscose fiber and modal fiber is: 10-50% collagen-modified viscose fiber and 50-90% modal fiber.

[0010] Furthermore, in the collagen-modified viscose fiber, the weight percentage of collagen is 10-45%.

[0011] Furthermore, the thickness of the first yarn is 30~50S, and the thickness of the second yarn is 20~40D.

[0012] Furthermore, the first yarn has a yarn length of 14~29cm / 50 stitches, and the second yarn has a yarn length of 4.4~9.2cm / 50 stitches.

[0013] Furthermore, the first yarn has a yarn length of 25~29cm / 50 stitches, and the second yarn has a yarn length of 7.8~9.2cm / 50 stitches.

[0014] Furthermore, the knitted fabric has a double-sided structure, comprising a skin-contact layer and a surface layer. The skin-contact layer has a plurality of first protrusions spaced apart, and the surface layer has a plurality of second protrusions spaced apart.

[0015] Furthermore, the knitted fabric's weave pattern is an eight-way cycle, and the weave pattern is as follows:

[0016] The first and second routes consist of knit stitches forming a circle, knit stitches forming a circle, and purl stitches forming a circle.

[0017] The third, fourth, seventh, and eighth rows are formed by purl stitches forming circles, purl stitches forming circles, and knit stitches forming circles.

[0018] The fifth and sixth rows consist of knitting in a circle, knitting in a cluster, and knitting in a circle;

[0019] Each path contains a first yarn and a second yarn.

[0020] Furthermore, the knitted fabric has a knitting structure with two needle tracks on the upper needle plate and one needle track on the lower needle cylinder.

[0021] Compared with existing technologies, the collagen-based antibacterial, deodorizing, and comfortable knitted fabric of the present invention has the following beneficial effects:

[0022] 1) The present invention describes a collagen-modified antibacterial and deodorizing knitted fabric. Collagen-modified viscose fiber gives the fabric antibacterial and deodorizing functions. The antibacterial and deodorizing functions originate from the collagen-modified viscose fiber itself. After being introduced into the fabric, the antibacterial and deodorizing effect is more lasting.

[0023] 2) The collagen-modified antibacterial, deodorizing, and comfortable knitted fabric of the present invention uses collagen as the main component of human skin. Collagen-modified viscose fiber gives the fabric excellent skin-friendliness and biocompatibility, and can also improve skin affinity and comfort during daily wear without having a negative impact on the skin and the environment.

[0024] 3) The collagen antibacterial and deodorizing comfortable knitted fabric of the present invention does not require the use of antibacterial and deodorizing additives, thus reducing environmental pollution and lowering production costs.

[0025] 4) The collagen antibacterial, deodorizing, and comfortable knitted fabric of the present invention has multiple first protrusion structures spaced apart in the skin-contact layer. These first protrusion structures directly contact the skin, forming tiny support points, reducing the full-area contact between the fabric and the skin, thereby improving the breathability of the fabric and its ability to absorb and wick away moisture. The protrusion structures form tiny air channels between the protrusion structures and the skin, which not only reduces stuffiness and facilitates air circulation and rapid moisture removal, keeping the skin dry, but also reduces stickiness. With a large area of ​​the skin suspended, sweat does not easily stick to the clothes, improving comfort during exercise or in hot environments.

[0026] 5) The collagen-modified antibacterial, deodorizing, and comfortable knitted fabric of this invention comprises collagen-modified viscose fiber, modal fiber, and spandex. The first yarn is a blend of collagen-modified viscose fiber and modal fiber, which imparts excellent moisture absorption and comfort to the fabric. The second yarn, spandex, provides the fabric with good elasticity and stretch. The first and second yarns are interconnected with the knitting pattern, jointly improving the fabric's moisture absorption, breathability, and comfort. Attached Figure Description

Furthermore, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated.

[0032] In the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0034] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] Existing technologies offer antibacterial and deodorizing fabrics, but their effects are not long-lasting and often involve chemical methods, which may have negative impacts on the skin and the environment. Furthermore, some fabrics are prone to problems such as poor moisture absorption and poor comfort during long-term wear.

[0036] To address the aforementioned technical issues, the applicant proposes a collagen-modified, antibacterial, deodorizing, and comfortable knitted fabric. The knitted fabric comprises a first yarn and a second yarn. The first yarn is a blend of collagen-modified viscose fiber and modal fiber, and the second yarn is spandex.

[0037] The collagen-infused antibacterial, deodorizing, and comfortable knitted fabric of this invention has the following advantages:

[0038] 1. Using collagen-modified viscose fiber, the fabric is given antibacterial and deodorizing functions, and the antibacterial and deodorizing effect is long-lasting.

[0039] Second, collagen is the main component of human skin. Collagen-modified viscose fiber gives the fabric excellent skin-friendliness and biocompatibility, and will not have a negative impact on the skin and the environment.

[0040] Third, no antibacterial and deodorizing additives are needed, which reduces environmental pollution and lowers production costs.

[0041] Fourth, Modal fiber offers a superior soft touch, silky luster, and excellent moisture-wicking ability, solving the problems of poor moisture absorption and comfort associated with traditional synthetic fiber fabrics. At the same time, Modal fiber improves the durability of the fabric.

[0042] 5. Spandex gives the fabric good elasticity and stretch.

[0043] Specifically, the weight percentage of the first yarn is 94-96%, and the weight percentage of the second yarn is 4-6%.

[0044] It achieved this ingeniously:

[0045] 1. Maximize functionality: Ensure that the advantages of collagen-modified viscose fiber and modal fiber are fully realized.

[0046] 2. Optimized elasticity: Provides just the right amount of elastic support from the spandex, avoiding the drawbacks of excessive elasticity.

[0047] 3. Production feasibility: It ensures the smoothness and stability of the entire process from spinning and weaving to dyeing and finishing.

[0048] 4. Cost rationalization: A balance was found between high-end features and controllable costs.

[0049] Specifically, in the first yarn, the blending mass ratio of collagen-modified viscose fiber and modal fiber is: 10-50% collagen-modified viscose fiber and 50-90% modal fiber.

[0050] A high proportion of modal provides exceptional softness, luster, wet strength, and moisture-wicking ability, making the fabric durable and comfortable; balancing the properties of each fiber ensures that the final fabric has good elasticity, comfort, antibacterial and deodorizing effects.

[0051] Collagen-modified viscose fiber, also known as collagen-regenerated cellulose fiber, will not be elaborated here as the preparation method and specific steps are existing technologies.

[0052] Specifically, unlike existing technologies, in the collagen-modified viscose fiber, collagen accounts for 10-45% by weight.

[0053] Collagen accounts for 10-45% of the weight, ensuring that the fabric has excellent antibacterial, deodorizing, and skin-friendly moisturizing functions without reducing the fabric strength.

[0054] The collagen-modified viscose fiber is obtained by adding a collagen solution to the viscose spinning solution and spinning it. The amount of collagen solution added accounts for 10% to 45% of the mass of the viscose spinning solution.

[0055] If the amount of collagen solution added is less than 10% of the mass of the viscose spinning solution, the effective antibacterial and deodorizing properties of the collagen-modified viscose fiber cannot be guaranteed. If the amount of collagen solution added is greater than 45% of the mass of the viscose spinning solution, the strength of the collagen-modified viscose fiber will decrease significantly.

[0056] Specifically, the thickness of the first yarn is 30~50S, and the thickness of the second yarn is 20~40D.

[0057] Specifically, the first yarn has a length of 14~29cm / 50 stitches, and the second yarn has a length of 4.4~9.2cm / 50 stitches.

[0058] Furthermore, the first yarn has a yarn length of 25~29cm / 50 stitches, and the second yarn has a yarn length of 7.8~9.2cm / 50 stitches.

[0059] Specifically, the knitted fabric has a double-sided structure, comprising a skin-contact layer and a surface layer. The skin-contact layer has a plurality of first protrusions spaced apart, and the surface layer has a plurality of second protrusions spaced apart.

[0060] These first raised structures come into direct contact with the skin, forming tiny support points and reducing the amount of fabric adhering to the skin. The raised structures create tiny air channels between the fabric and the skin, which not only reduces stuffiness and promotes air circulation and rapid moisture removal, keeping the skin dry, but also reduces stickiness. With a large area of ​​skin suspended, sweat is less likely to stick to clothing, improving comfort during exercise or in hot environments. These second raised structures also enhance the fabric's aesthetics.

[0061] Specifically, such as Figure 3 As shown, a bamboo-like structure is formed on the first protruding structure.

[0062] This design has the following advantages:

[0063] I. Significantly Enhanced Moisture-Ward and Quick-Drying Performance: The alternating segments of the bamboo structure create micro-gradient grooves on the raised surface. These irregular textures more effectively capture sweat from the skin's surface and rapidly diffuse liquid sweat laterally to the larger surface area of ​​the raised area through capillary action, thereby accelerating moisture evaporation. Compared to smooth raised areas, the bamboo-textured raised areas have a significantly increased surface area, providing more sites for moisture evaporation and doubling the fabric's moisture-wicking and quick-drying performance.

[0064] II. Ultimate Contact Comfort and "Anti-Stickiness": The bamboo-like structure transforms the contact between the raised tops and the skin from a "small plane" to "discontinuous dots or short lines," further reducing the physical contact area. This is especially important when the skin sweats, greatly preventing wet fabric from completely sticking to the skin and maintaining a refreshing, "almost-away" feel. Compared to perfectly regular raised sections, the irregular bamboo texture better mimics the texture of natural fabrics or skin itself, resulting in a richer, softer feel, reducing the "stiffness" of synthetic fabrics, and enhancing the psychological experience of skin-friendliness.

[0065] III. Exceptional Visual and Tactile Aesthetic Value: The slub structure imparts a natural, irregular three-dimensional texture and soft sheen to the fabric. This elevates the functional fabric beyond a monotonous appearance, giving it the feel and style of high-end ready-to-wear or casual wear. This permanent texture, achieved through complex weaving rather than simple printing, reflects the high level of technological sophistication in textile craftsmanship, significantly enhancing the product's market differentiation and perceived value.

[0066] IV. Enhanced aerodynamic effect: The irregular bamboo-like structure on the protrusions can generate micro-disturbances in the micro-air layer near the skin, which may help to more efficiently remove water vapor and heat evaporated from the skin surface, further enhancing the breathability and heat dissipation effect.

[0067] Specifically, the knitted fabric has a pattern that repeats in eight rows, and the knitting pattern is as follows:

[0068] The first and second routes consist of knit stitches forming a circle, knit stitches forming a circle, and purl stitches forming a circle.

[0069] The third, fourth, seventh, and eighth rows are formed by purl stitches forming circles, purl stitches forming circles, and knit stitches forming circles.

[0070] The fifth and sixth rows consist of knitting in a circle, knitting in a cluster, and knitting in a circle;

[0071] Each path contains a first yarn and a second yarn.

[0072] Collagen-modified viscose fiber, modal fiber and spandex interact with each other, the first yarn, the second yarn and the weaving pattern are related to each other, so that the skin-contact layer has multiple first protrusion structures distributed at intervals, which together improve the fabric’s moisture absorption, breathability and comfort.

[0073] Specifically, the knitted fabric has a three-needle knitting structure.

[0074] More specifically, the knitted fabric has a knitting structure with two needle tracks on the upper needle plate and one needle track on the lower needle cylinder.

[0075] The preparation process of the knitted fabric includes the following steps:

[0076] S1. Yarn preparation;

[0077] S2, Greige fabric weaving;

[0078] S3. Dyeing of greige fabric;

[0079] S4. Fabric finishing.

[0080] It is important to note that during the manufacturing process of knitted fabrics, contact with strong acids, strong alkalis, and biological enzymes should be avoided to prevent affecting the activity of collagen.

[0081] Specifically, in step S3, the dyeing of the greige fabric includes the following steps:

[0082] S31, Pre-processing;

[0083] S32, staining.

[0084] Specifically, in step S31, the pretreatment includes rinsing the fabric with clean water, adding vitamin C during the rinsing process to provide antioxidant protection for collagen, which is beneficial for subsequent high-temperature setting.

[0085] Specifically, in step S32, low-temperature active staining is performed at 80°C to ensure that the lipid-soluble active substances are not damaged.

[0086] Specifically, in step S4, the fabric finishing process includes the following steps:

[0087] S41, softening treatment;

[0088] S42, Drying;

[0089] S43, Sterilization by a sterilization machine.

[0090] Specifically, in step S41, the softening treatment uses a hydrophilic softener, and the amount of hydrophilic softener used is reduced by 30-50% compared to the amount used for the same weight of pure cotton.

[0091] Specifically, in step S41, it is not recommended to use silicone oil-based softeners for softening. If softening is required, it is recommended to use hydrophilic softeners, and the amount used should be reduced by about 30%-50% compared to the amount used for the same weight of pure cotton, depending on the blended material and proportion.

[0092] Specifically, in step S42, a rotary drum dryer is used. During the drying process, the air volume can be increased to accelerate the evaporation of moisture. In principle, the lower the temperature and the shorter the time, the better. Dry drying is better than wet drying.

[0093] This is because collagen is resistant to dry heat but susceptible to humid heat. Steam drying should be avoided, and moisture should be removed as much as possible before drying. Rotary drying is recommended.

[0094] Specifically, in step S43, the setting temperature of the setting machine is 165~185℃.

[0095] When washing knitted fabrics, users should use neutral detergents (laundry detergent) as much as possible, shorten the soaking time, and hand wash at low temperatures to prolong the collagen degradation period, because collagen is relatively resistant to dry heat but susceptible to humid heat.

[0096] The manufacturing processes of knitted fabrics are interconnected, working together to ensure that knitted fabrics possess antibacterial and deodorizing properties while also being soft, comfortable, durable, and long-lasting.
