Description

Technical Field

[0001] This application relates to the field of composite nylon knitted fabrics, and more specifically, to a high-elastic double-sided knitted fabric and its preparation process. Background Technology

[0002] With the global popularity of yoga, it is gaining increasing popularity as a form of exercise that promotes physical and mental health and improves quality of life. During yoga practice, the body generates a significant amount of heat and sweat, thus placing increasingly stringent demands on clothing fabrics. In particular, the moisture-wicking and breathable properties of the fabric directly affect the practitioner's comfort and performance.

[0003] In yoga practice, practitioners need to perform a series of complex and varied postures, which often involve significant stretching and twisting, placing high demands on the elasticity and freedom of movement of clothing fabrics. More importantly, continuous exercise raises body temperature, opens skin pores, and causes profuse sweating. If the fabric lacks moisture absorption and breathability, sweat will remain on the skin's surface, affecting not only the practitioner's comfort but also potentially causing skin problems and even compromising the safety and effectiveness of the exercise.

[0004] Therefore, there is an urgent need in the market for a more moisture-wicking and breathable fabric. Summary of the Invention

[0005] To enhance the moisture absorption and breathability of the fabric and make it softer and more comfortable, this application provides a high-elastic double-sided knitted fabric and its preparation process.

[0006] In a first aspect, this application provides a process for preparing a high-elasticity double-sided knitted fabric, which adopts the following technical solution: A process for preparing a high-elasticity double-sided knitted fabric includes the following steps: Step 1: Degrease the grease fabric; the grease fabric is woven from nylon 66 and spandex using a double-sided high-speed weft knitting circular knitting machine; Step 2: Dye the degreased fabric to obtain dyed fabric; Step 3: Dry the dyed fabric and impregnate it with the finishing solution to obtain the impregnated fabric; wherein, the finishing solution includes 5-10 g / L polydimethylsiloxane, 5-10 g / L amino silicone oil, 1-5 g / L nonionic surfactant, 5-15 g / L polyurethane emulsion, 5-15 g / L plant extract, and water, wherein the plant extract is prepared from at least peppermint, aloe vera, and seaweed, and the mass ratio of peppermint, aloe vera, and seaweed is (0.3-0.7):(0.8-1.2):(0.8-1.2); Step 4: Dry the impregnated fabric, stretch and set it to obtain a high-elastic double-sided knitted fabric.

[0007] The fabric provided in this application uses nylon 66 fiber as the base material, combined with spandex, and is woven using a double-sided weft knitting circular knitting machine. After dyeing and finishing processes, the finished fabric is obtained. It is used in yoga wear and other apparel fabrics. This fabric features moisture absorption and breathability, medium-strength four-way stretch, fluffy and soft texture, skin-friendly comfort, a soft and bare feel, and 360-degree free stretch, meeting the modern consumer's pursuit of a healthy lifestyle and superior wearing experience.

[0008] By employing the above-mentioned technical solution, the plant extract, prepared from peppermint, aloe vera, and seaweed, rapidly penetrates into the fibers of the dyed fabric and adheres firmly. The hydrophilic components in aloe vera and seaweed significantly enhance the fabric's hydrophilicity, making it easier to absorb and retain moisture. Simultaneously, these components form a smooth, moisture-absorbing film on the fabric surface, reducing moisture accumulation and evaporation resistance. The active ingredients in the plant extract can also adhere to the fabric surface through chemical reactions or physical adsorption, forming a thin hydrophilic film. This film increases the contact area between the fabric and water molecules, improving the fabric's moisture absorption.

[0009] Furthermore, the polysaccharides and saponins in the special plant extracts can penetrate into the interfiber spaces of the fabric, improving the way the fibers bond and creating more microchannels between them. These channels facilitate the rapid transfer and evaporation of moisture, thereby improving the fabric's breathability and quick-drying properties.

[0010] The menthol and other components in plant extracts can give fabrics a cooling sensation. Although this does not directly enhance moisture absorption and breathability, the cooling sensation may help reduce the stuffiness when wearing the fabric, indirectly improving wearing comfort and enhancing the overall user experience.

[0011] Through synergistic effects, plant extracts can significantly improve the moisture absorption, breathability, and wearing comfort of fabrics. This improvement is not only reflected in physical properties—the cooling and moisturizing effects can reduce the stuffiness of wearing them in summer—but also enhances the user's sensory experience.

[0012] Furthermore, the active ingredients in plant extracts, such as polysaccharides in aloe vera, polysaccharides and proteins in seaweed, and certain alcohols or esters in peppermint, can be adsorbed onto the surface of fabric fibers. These components can reduce the surface tension of the fibers, making it easier for them to expand their surface and stretch their length, thus making the fabric fluffy, full, and soft to the touch. Some components in plant extracts can also form a lubricating layer between fibers, reducing the coefficient of friction between fibers, making it easier for fibers to slide and stretch within the fabric, further enhancing softness. The moisturizing factors contained in aloe vera, seaweed, and other similar ingredients can also penetrate into the fibers, maintaining fiber moisture, enhancing fiber toughness, and helping the fibers better recover their original shape after being subjected to external forces, thereby improving elasticity.

[0013] Preferably, the finishing solution comprises 8 g / L polydimethylsiloxane, 5 g / L amino silicone oil, 3 g / L nonionic surfactant, 10 g / L polyurethane emulsion, 12 g / L plant extract, and water.

[0014] By adopting the above technical solution, the dosage and combination of each raw material in the finishing solution can be further limited. This not only fully leverages the synergistic effect between plant extracts and dyed fabrics, but also allows other raw materials to play a more significant role, thereby enhancing the treatment effect on the fabric.

[0015] Preferably, the method for preparing the plant extract includes the following steps: Step a: Mix peppermint, aloe vera, and seaweed in a preparation mass ratio of (0.3-0.7):(0.8-1.2):(0.8-1.2), and soak in water for 4-6 hours to obtain a plant mixture; Step b: Ultrasonically disperse the plant mixture at 55-65℃ and 500-600W for 20-30 minutes to obtain the plant treatment. Step c: Solid-liquid separation of the plant treatment material, the liquid part being the plant extract.

[0016] By adopting the above technical solution, the preparation of plant extracts is further limited to ultrasonic conditions of 55-65℃ and 500-600W, which allows more effective active substances from peppermint, aloe vera, and seaweed to be extracted and to more fully treat the fabric.

[0017] Preferably, the peppermint, aloe vera, and seaweed are mixed in a preparation mass ratio of 0.5:1:1.

[0018] Preferably, the nonionic surfactant includes at least one or a mixture of secondary alcohol polyoxyethylene ether, sodium stearate, Tween, and fatty alcohol polyoxyethylene ether.

[0019] Preferably, the nonionic surfactant is secondary alcohol polyoxyethylene ether or Tween, and the amount of secondary alcohol polyoxyethylene ether or Tween is (0.8-1.2):(0.8-1.2).

[0020] By adopting the above technical solution, the dosage ratio of secondary alcohol polyoxyethylene ether and Tween is further limited. Their synergistic effect reduces the individual usage while achieving the same finishing effect, thereby lowering costs and reducing environmental impact. The emulsifying ability of secondary alcohol polyoxyethylene ether combined with the dispersing properties of Tween creates more stable and finer emulsion droplets, thus improving emulsification efficiency. The strong penetrating power of secondary alcohol polyoxyethylene ether helps surfactants such as Tween penetrate deeper into the fabric fibers, allowing the finishing agent to function more effectively.

[0021] Secondly, this application provides a high-elasticity double-sided knitted fabric.

[0022] Preferably, the nylon 66 is 40D / 51F DTY and the spandex is 40D.

[0023] Preferably, the fabric comprises 75-85% nylon 66 and 15-25% spandex by weight percentage.

[0024] By adopting the above technical solution, this application uses unique high-performance ultra-fine denier nylon 66 40D / 51F DTY fiber as the base material, combined with 40D spandex. The nylon 66 DTY yarn employs a unique polymerization process, endowing it with excellent tensile strength, as well as superior elasticity and resilience. Through a special false-twist technique, the multi-strand 51F yarn is densely spun and dotted, greatly enhancing the yarn's bulkiness and abrasion resistance. The nylon 66 yarn exhibits a soft touch and moderate luster similar to natural fibers. When interwoven with 40D spandex, it gives the fabric exceptional fatigue resistance, unique stability, and durability.

[0025] Relying on precise yarn blending and weaving techniques, as well as unique finishing processes, this fabric achieves a seamless fit, giving it the dryness, breathability, and skin-friendliness of natural cotton fibers, while also providing a bouncy, full, and fleshy tactile experience, like a second skin.

[0026] The synergistic effect of specially selected spandex and nylon 66 gives the fabric excellent four-way stretch properties, effectively matching the dynamic needs of the human body.

[0027] In summary, this application has the following beneficial effects: 1. Exceptional Bare Skin Feel: Utilizing precise yarn blending and weaving techniques, along with unique finishing processes, it achieves a seamless, close-fitting wearing experience, feeling like a second skin. The fabric is moisture-wicking and breathable, with medium-strength four-way stretch, fluffy and soft, skin-friendly and comfortable, offering a soft, bare-skin feel and 360-degree free stretch, satisfying modern consumers' pursuit of a healthy lifestyle and superior wearing experience.

[0028] 2. All-around elasticity: The synergistic effect of specially selected spandex and nylon 66 gives the fabric excellent four-way stretch properties, effectively matching the dynamic needs of the human body.

[0029] 3. Ecological compatibility: We advocate green production strategies throughout the entire process to reduce chemical consumption and promote the sustainable development of the textile industry.

[0030] 4. Significant moisture absorption and breathability: Special plant extracts significantly enhance the fabric's moisture absorption, breathability, and wearing comfort. This improvement is not only reflected in physical properties—the cooling and moisturizing effects reduce the stuffiness of summer wear—but also improve the user's sensory experience.

The finishing solution is obtained by mixing the various raw materials until they are homogeneous.

[0098] Performance testing 1. Air permeability: The air permeability of the high-elastic double-sided knitted fabrics of Examples 1-7 and Comparative Examples 1-5 was tested according to GB / T5453-1997 "Determination of air permeability of textile fabrics". The airflow rate passing vertically through a given area of ​​the sample within a certain time was measured and the results were recorded in Table 1.

[0099] 2. Moisture absorption: The moisture absorption properties of the high-elastic double-sided knitted fabrics of Examples 1-7 and Comparative Examples 1-5 were tested according to the national standard GB / T21655.1-2008 "Evaluation of moisture absorption and quick-drying properties - Part 1: Single combination test method". The water absorption rate is recorded in Table 1.

[0100] 3. Hand Feel Evaluation: Ten experienced craftsmen were selected to evaluate the hand feel of the high-elastic double-sided knitted fabrics from Examples 1-7 and Comparative Examples 1-5. The hand feel evaluation mainly focused on softness, elasticity, and coolness. A score of 0-10 was used as the standard, with a score of 6 or higher considered acceptable for softness and elasticity. The closer to 10, the softer and more elastic the fabric; the closer to 0, the stiffer and less elastic the fabric.

[0101] The softness / elasticity score was calculated as the average score of 10 experienced craftsmen and recorded in Table 1.

[0102] Table 1 According to the comparison of test data in Table 1, the high-elastic double-knitted fabrics of Examples 1-7 are significantly better than those of Comparative Example 5 in terms of breathability, moisture absorption, softness, and elasticity. The data shows that whether or not the finishing solution used for the fabric contains plant extracts makes a significant difference in the treatment effect; plant extracts can indeed effectively enhance breathability and moisture absorption, and make the fabric feel softer and more elastic.

[0103] Comparative Examples 1-3, based on Example 1, disrupted the specific combination of peppermint, aloe vera, and seaweed in the plant extracts; Comparative Example 4, based on Example 1, disrupted the specific dosage ratio of peppermint, aloe vera, and seaweed in the plant extracts. According to the test data in Table 1, the fabric of Example 1 has better breathability, higher water absorption, and a better hand feel than Comparative Examples 1-4. This indicates that after disrupting the specific combination of peppermint, aloe vera, and seaweed, Comparative Examples 1-4 could not fully utilize the special synergistic effect between the three, resulting in a significant decrease in the fabric's moisture absorption and breathability, hand feel, and other aspects, thus failing to perform its intended function. Therefore, it is necessary to strictly limit the types and dosage ratios of plant extracts.

[0104] Examples 4-5 are based on Example 1, with the temperature in step b changed; Examples 6-7 are based on Example 1, with the ultrasonic power in step b changed. According to the test data in Table 1, the performance of the high-elastic double-knitted fabric in Examples 4-7 decreased in various aspects. In other words, if the parameters for extracting mint, aloe vera, and seaweed in step b can be further limited, more effective active substances can be extracted, resulting in a better treatment effect on the fabric.

[0105] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
