Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of T-shirt fabric, in particular to a durable waterproof and breathable T-shirt fabric and a production method thereof. BACKGROUND

[0002] T-shirt fabric is a typical representative of the combination of textile technology and wearing demand. Its development process from basic natural fibers to today's rich and colorful functional blends is behind a series of evolution of textile technology. The development of modern T-shirt fabric has gone from pursuing basic comfort to different functional segmentation, and is rapidly evolving towards green environmental protection and intelligent integration. T-shirt fabric is almost knitted structure, the most common is weft-knitted fabric, which has good fabric elasticity, softness and comfort; warp-knitted fabric has also rapidly developed in this field in recent years, which has stable structure, long-lasting wear resistance, and especially with the development of functional yarns, it can provide different functional requirements to make the garment have better wearing experience.

[0003] Nowadays, chemical fiber waterproof fabric has wide popularity in the market, which is used for outdoor sports, commuting and fashion clothing, and gradually expands in the field of T-shirt fabric. The existing processing methods of chemical fiber waterproof fabric mainly include three types: laminating film, coating and adding waterproof additives. Among them, the chemical fiber elastic fabric generally uses the processing method of adding waterproof additives, which will not affect the elasticity and breathability; the working principle of adding waterproof additives is to apply a layer of low surface energy waterproof agent (usually fluorocarbon) on the surface of the fiber, so that the water contact angle is increased, the effect of water bead rolling is formed, and the surface of the fabric is prevented from being wetted by water. However, the waterproof performance of the fabric with this type of waterproof additive will gradually fail with the increase of washing and wear times.

[0004] Some fabrics are woven with waterproof yarns, which can increase the washing resistance by adding waterproof agents during spinning, but will increase the difficulty of fabric dyeing, and problems such as color mottle and color spots are easy to occur during dyeing. SUMMARY

[0005] The present application aims to provide a durable waterproof and breathable T-shirt fabric and a production method thereof, which can solve at least one of the above problems.

[0006] According to one aspect of the present application, a durable waterproof and breathable T-shirt fabric is provided, which comprises a fabric body formed by 40 / 34F matte high-elasticity polyamide 66 waterproof yarn and 30D spandex, and the fabric body is knitted by three guide bars. The guide bar number GB1 and GB2 are both made of 40 / 34F matte high-elasticity polyamide 66 waterproof yarn, and the guide bar number GB3 is made of 30D spandex. The guide bar number GB1 adopts a 1-by-1 empty form, and the guide bar numbers GB1 and GB2 both adopt warp plain stitches.

[0007] In some embodiments, the fabric body has the following organizational structure: GB1: 1-0 / 1-2 / 2-3 / 2-1 / / , adopting 1 through 1 through; GB2: 1-0 / 1-2 / / , full penetration; GB3: 1-2 / 1-0 / / , full penetration.

[0008] According to another aspect of the present invention, a method for producing a durable waterproof and breathable T-shirt fabric is provided, comprising the following steps: S1. Select a 130-inch three-comb 32-needle Karl Mayer HKS 3-1 warp knitting machine; S2. The fabric body is woven in the selected warp knitting machine using the corresponding yarn and according to the structure to obtain the fabric body. S3. The fabric body obtained by the above weaving is subjected to dyeing and finishing processes. The dyeing and finishing process is as follows: washing - pre-setting - dyeing - post-setting.

[0009] In some embodiments, the pre-setting temperature in step S3 is 190~195℃, the machine speed is 18~20 m / min, and the fabric body's unrolled specifications are a width of 174cm and a weight of 150g / m². 2 .

[0010] In some embodiments, the staining temperature in step S3 is 105°C.

[0011] In some embodiments, the post-setting temperature in step S3 is 155~160℃, the machine speed is 30 m / min, and the fabric body's specifications after finishing are a width of 165cm and a weight of 160g / m². 2 .

[0012] The beneficial effects of this invention are: 1. During the weaving process, GB1 adopts a warp satin structure with one thread and one hole. After weaving in this way, the tension is different due to the density of the extension threads, and the density of adjacent loops in the same horizontal row changes. The denser position can increase the fabric's UV resistance and provide good sun protection. The sparser position forms a microporous structure, which allows air to circulate and can also quickly expel body moisture, thereby enhancing the fabric's breathability. At the same time, this alternation of density can create a twill jacquard effect on the surface of the fabric. 2. In the fabric itself, 40 / 34F matte high-elastic nylon 66 waterproof yarn is used in both GB1 and GB2 to achieve a waterproof effect. At the same time, it prevents the fabric from clogging the ventilation micropores after it gets wet, so that the fabric has excellent and long-lasting breathability. 3. The 40 / 34F matte high-elastic nylon 66 waterproof yarn in the fabric body obtained by the production method of the present invention adopts a corresponding weaving method with short extension lines, which makes the fabric have excellent anti-snagging and anti-pilling effects. Moreover, this structure is stable, with small deformation after stretching, and its waterproof function will not be weakened after stretching. At the same time, the use of relatively fine spandex makes the fabric less elastic, with good stability, and gives the fabric good drape. 4. When the fabric body obtained by this production method is dyed at a temperature of 105℃, the diffusion rate of the dye can be increased, making the dye molecules move faster and migrate more easily from high concentration areas to low concentration areas. This corrects the unevenness of the initial dyeing of the fabric, achieves uniform dyeing, and improves the effect of color variation. Attached Figure Description

[0013] Figure 1 This is a schematic diagram of the structure of a durable, waterproof, and breathable T-shirt fabric. Detailed Implementation

[0014] The present invention will now be described in further detail with reference to the accompanying drawings.

[0015] Reference Figure 1 A durable waterproof and breathable T-shirt fabric includes a fabric body woven from 40 / 34F matte high-elastic nylon 66 waterproof yarn and 30D spandex. The fabric body is woven with three combs. Combs GB1 and GB2 are both made of 40 / 34F matte high-elastic nylon 66 waterproof yarn, and comb GB3 is made of 30D spandex. Comb GB1 is woven with a 1-through-1-open pattern. Combs GB1 and GB2 are both woven with a warp plain weave.

[0016] The fabric's structure is as follows: GB1: 1-0 / 1-2 / 2-3 / 2-1 / / , adopting 1 through 1 through; GB2: 1-0 / 1-2 / / , full penetration; GB3: 1-2 / 1-0 / / , full penetration.

[0017] The fabric itself uses appropriate yarns and a specific weave structure, which creates many tiny ventilation holes during the weaving process. These micropores allow air to circulate and quickly expel moisture generated by the body. At the same time, it works in conjunction with 40 / 34F matte high-elastic nylon 66 waterproof yarn to prevent the fabric from clogging the ventilation micropores when wet, thus maintaining the fabric's long-lasting waterproof and breathable effect and ensuring an excellent wearing experience.

[0018] When weaving the fabric itself, GB1 uses a 1-through-1-open weave with a warp satin structure. In this way, the density of the extension lines in the same horizontal row varies, which means that the stress is different due to the density of the extension lines. The density of adjacent loops in the same horizontal row changes. The denser position can increase the fabric's UV resistance, while the sparser position forms a microporous structure, which enhances the fabric's breathability. At the same time, this alternation of density creates a twill jacquard effect on the surface.

[0019] The 40 / 34F matte high-elastic nylon 66 waterproof yarn, after weaving, has a short extension line, giving the fabric excellent anti-snagging and anti-pilling properties. Its stable structure results in minimal deformation after stretching, and its waterproof function does not diminish even after elongation. Simultaneously, the use of 30D spandex, a relatively finer type, minimizes the elasticity of the woven fabric, ensuring good stability and excellent drape.

[0020] A method for producing a durable waterproof and breathable T-shirt fabric includes the following steps: S1. Select a 130-inch three-comb 32-needle Karl Mayer HKS 3-1 warp knitting machine; S2. The fabric body is woven in the selected warp knitting machine using the corresponding yarn and according to the structure to obtain the fabric body. S3. The fabric body obtained by the above weaving is subjected to dyeing and finishing processes. The dyeing and finishing process is as follows: washing - pre-setting - dyeing - post-setting.

[0021] In step S3, the initial shaping is performed in a shaping machine. The shaping temperature is 190~195℃, which can be 190℃, 192℃, or 195℃. The machine speed is 18~20 meters / minute, which can be 18 meters / minute, 19 meters / minute, or 20 meters / minute. After the initial shaping, the fabric body's specifications are a width of 174cm and a weight of 150g / m². 2 .

[0022] In step S3, the dyeing temperature is 105℃, which is higher than the traditional dyeing temperature. This temperature can ensure the stability of the fabric and increase the diffusion rate of the dye, making the dye molecules move faster and migrate more easily from high concentration areas to low concentration areas. This corrects the unevenness of the initial dyeing of the fabric, achieves uniform dyeing, and improves the color spots and blemishes that may occur due to waterproof yarn.

[0023] In step S3, post-setting is performed in a setting machine at a temperature of 155~160℃, which can be 155℃, 158℃, or 160℃. The machine speed is 30 meters per minute, and the fabric's dimensions upon exiting the machine are a width of 165cm and a weight of 160g / m². 2 .

[0024] In actual production, no waterproofing agents are added during the post-dyeing setting process to avoid affecting the waterproof effect of the fabric.

[0025] The production method of the durable waterproof and breathable T-shirt fabric of this invention produces a fabric body that is finished after post-setting and processing. The fabric is then tested, and the results are as follows: Snag test according to GB / T11047—2008: warp grade 4, weft grade 3-4; Pilling test according to GB / T 4802.1 E: warp grade 4-5, weft grade 4-5; Passes UV 50+ test (GB / T18830-2009); Water repellency test GB / T 4745-2012: grade 4; Water repellency after 30 washes: grade 4; Breathability (mm / s) GB / T 5453-1997: 420; The fabric body is subjected to the ASTMD 4964 10LBF tensile test method, and the test results are as follows: Elongation % Recovery % Modulus 20 % Modulus 40 % Modulus 60 % Warp 70% 96% 0.63 lbf 1.96 lbf 5.2 lbf Fill 124% 94% 0.2 lbf 0.7 lbf 1.4 lbf The test data in the table above shows that the fabric has moderate warp and weft stretch and good recovery rate, making it suitable for T-shirt fabrics and comfortable to wear.

[0026] In summary, the fabric obtained by this invention has excellent waterproof and breathable properties, and the breathability is long-lasting. The fabric has low elasticity, good stability, and achieves uniform dyeing.

[0027] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the inventive concept of the present invention, and these all fall within the protection scope of the present invention.
