Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a moisture-proof knitted fabric. Background Technology

[0002] With the improvement of people's living standards and the increasing demand for functional clothing, the need for knitted fabrics with moisture-wicking properties is becoming more and more urgent in many fields such as outdoor sports, sports leisure, and daily wear.

[0003] Traditional knitted fabrics often fall short in meeting the requirements for moisture-wicking functionality. Some ordinary fabrics, due to their simple structural design and improper yarn selection, cannot effectively block the penetration of external moisture. When exposed to water or when the body sweats, they easily become soaked, causing discomfort to the wearer and affecting the warmth and aesthetics of the garment. In the field of high-performance fabrics, although some moisture-wicking products exist, they often suffer from poor comfort. Some waterproof and breathable fabrics achieve their function through multi-layer composite structures. While they have a certain effect in terms of waterproofing, the large number of layers makes the fabric heavy overall, affecting the softness and flexibility of the garment, and failing to meet people's needs for comfort and moisture-wicking performance.

[0004] Therefore, providing a solution that can effectively achieve moisture-proof functionality has significant market value. Utility Model Content

[0030] Example 1

[0031] This embodiment provides a moisture-proof knitted fabric, characterized in that the fabric body includes: a moisture-proof layer 1, a water-repellent layer 2 connected to the bottom of the moisture-proof layer 1, and a moisture-absorbing layer 3 connected to the top of the moisture-proof layer 1.

[0032] The moisture-proof knitted fabric is woven on a double-sided circular knitting machine; the moisture-proof layer 1 is formed from top to bottom by a two-needle upper needle plate and a four-needle lower needle cylinder knitted in a six-way cycle: wherein,

[0033] The first row consists of: upper needle plate circular tissue, upper needle plate floating thread tissue, lower syringe circular tissue, lower syringe floating thread tissue, lower syringe circular tissue, and lower syringe floating thread tissue.

[0034] The second row consists of: upper needle plate floating thread tissue, upper needle plate tucking tissue, lower syringe loop tissue, lower syringe floating thread tissue, lower syringe floating thread tissue, and lower syringe loop tissue.

[0035] The third row consists of: upper needle plate floating thread tissue, upper needle plate circular tissue, lower syringe floating thread tissue, lower syringe floating thread tissue, lower syringe circular tissue, and lower syringe floating thread tissue.

[0036] The fourth row consists of: upper needle plate circular tissue, upper needle plate floating thread tissue, lower syringe floating thread tissue, lower syringe circular tissue, lower syringe floating thread tissue, and lower syringe circular tissue.

[0037] The fifth row consists of: upper needle plate floating thread tissue, upper needle plate tucking tissue, lower syringe loop tissue, lower syringe loop tissue, lower syringe floating thread tissue, and lower syringe floating thread tissue.

[0038] The sixth row consists of: upper needle plate circular tissue, upper needle plate floating thread tissue, lower syringe circular tissue, lower syringe floating thread tissue, lower syringe circular tissue, and lower syringe floating thread tissue.

[0039] The anti-permeability layer 1 is woven from anti-permeability polyester yarn;

[0040] The moisture-absorbing layer 3 has a ring-shaped structure, and the water-repellent layer 2 has a clustered structure.

[0041] The moisture-absorbing layer 3 is made of a blend of 50D / 36F cationic polyester, hydrophilic modified polyester yarn, and cotton yarn. The cationic polyester gives the fabric special dyeing properties, and its overall performance is improved when blended with hydrophilic modified polyester yarn and cotton yarn. Cotton yarn has natural hydrophilicity and good moisture absorption capacity, which can quickly absorb sweat from the surface of human skin, providing the initial moisture absorption power for the fabric. The hydrophilic modified polyester yarn, while maintaining the excellent properties of polyester fibers, further enhances the overall hydrophilicity, enabling the fabric to absorb and diffuse moisture more efficiently, accelerate the transfer of sweat from the skin surface to the external environment, effectively improve the comfort of wearing, and avoid the stuffiness and discomfort caused by sweat accumulation.

[0042] The second yarn used in the water-repellent layer 2 is a blend of water-repellent polyester yarn and nylon.

[0043] In this process, the waterproof layer 1 uses cotton yarn as a connecting yarn to link the water-repellent layer 2 and the moisture-absorbing layer 3 to form the waterproof knitted fabric.

[0044] Example 2

[0045] A method for preparing a moisture-wicking knitted fabric includes the following steps:

[0046] Step 1: Blend the 50D / 36F cationic polyester, the hydrophilic modified polyester yarn, and the cotton yarn to obtain the first yarn; blend the water-repellent polyester yarn with nylon to obtain the second yarn.

[0047] Step 2: Feed the impermeable polyester yarn, the first yarn, and the second yarn into a double-sided circular knitting machine to knit the impermeable knitted fabric.

[0048] Step 3: The moisture-proof knitted fabric is then subjected to a washing process, a pre-molding and shaping process, and a polyester dyeing process to obtain the final product.

[0049] The temperature of the preform shaping machine in the preform shaping process is 160℃, and the speed is 20m / min.

[0050] The polyester dyeing process includes the following steps:

[0051] Step S1: Inject soft water into the dyeing machine, add 1 g / L of glacial acetic acid, and then add a suitable disperse dye. Increase the temperature to 130°C at a rate of 1.2°C per minute. This heating rate allows the dye to be more evenly adsorbed onto the polyester fibers, reducing the risk of uneven coloring. Hold at 130°C for 45 minutes to ensure full dye penetration. Then, decrease the temperature to 80°C at a rate of 1.2°C per minute, add 1.5 g / L of caustic soda and 3 g / L of sodium hydrosulfite, and maintain for 25 minutes to promote dye fixation and even dyeing. Finally, decrease the temperature to 55°C at a rate of 1.2°C per minute, cut samples for color matching, confirm color accuracy, drain the water, and perform two washes to thoroughly remove excess dye and residual auxiliaries.

[0052] Step S2: Refill the dyeing machine with soft water, add 1.5g / L of reducing cleaning agent, 3g / L of soda ash, and 3g / L of sodium hydrosulfite. Heat to 80℃ at a rate of 1.2℃ per minute and hold for 25 minutes to effectively remove residual impurities and unfixed dyes from the dyeing process, improving color fastness. Then cool to 55℃, cut samples for color matching. After confirming the color is correct, drain the water and wash twice more to ensure the fabric is clean.

[0053] Step S3: Refill the dyeing machine with soft water. First, add 1.0g / L of dyeing acid to adjust the pH value of the dye bath. Then, add 2.5g / L of moisture-wicking finishing agent to enhance the fabric's moisture absorption and breathability, and 0.8g / L of oligomer dispersant to prevent oligomer deposition on the fabric. Increase the temperature to 80℃ at a rate of 1.2℃ per minute and hold for 35 minutes to allow the finishing agent to fully act on the fabric fibers. Then, cool to 55℃, cut and match the colors, drain the water accurately, and wash twice. Remove the fabric from the dyeing vat. At this point, the fabric not only has a bright and uniform color but also excellent moisture absorption, wicking, and breathability.

[0054] The three-layer structure design of this utility model, namely the waterproof layer, the water-repellent layer, and the moisture-absorbing layer, works together to form a highly efficient waterproof system. The water-repellent layer uses a second yarn made of water-repellent polyester yarn and nylon blended in a tucked weave, which further enhances the overall water-repellent ability of the fabric. The waterproof knitted fabric of this utility model has significant advantages in terms of waterproof performance, moisture-absorbing and breathable performance, and color appearance performance, and has broad market value.

[0055] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
