Description

Technical Field

[0001] This utility model relates to the field of textile technology, specifically to a windproof and light rainproof clothing fabric and sweatshirts and sweatpants containing the same. Background Technology

[0002] Currently, hoodies and sweatpants are the most widely worn clothing items for autumn and winter, as well as for sportswear and casual wear. Generally, hoodies and sweatpants are made from knitted fabrics to reflect their relaxed and casual style. However, knitted materials are made of interlocking loops, resulting in a relatively loose structure that is prone to holes, making them difficult to be windproof or waterproof. Therefore, traditional hoodies and sweatpants are not windproof and have poor warmth retention. In winter, they are typically worn as a mid-layer, trapping still air under outer clothing, thus providing excellent warmth. In windy and rainy outdoor environments, woven materials, with their tightly interwoven warp and weft yarns, are less prone to large holes. Outerwear such as windbreakers made from this type of fabric can be used as an outer layer to protect against wind and rain.

[0003] Waterproof clothing typically utilizes water-repellent treated fabrics or incorporates a waterproof layer to achieve its rain-repellent effect; examples include waterproof jackets. Water repellency refers to the deposition of hydrophobic compounds on the fiber surface, creating pores that allow air and moisture to pass through. This typically results in water droplets forming on the fabric surface (similar to the surface of a lotus leaf). It's not strictly waterproof, but rather reduces water absorption by the fabric, allowing water to be "repelled" from the surface. The water-repellent treatment lowers the surface tension of the fabric, causing water droplets to form a larger contact angle, resulting in a rolling effect rather than spreading out and soaking. However, whether the clothing gets wet depends on the amount of rain and the duration of exposure; water repellency is not true complete waterproofing.

[0004] Waterproof and breathable clothing fabrics generally refer to fabrics with a rubber backing, which can be either coated or laminated. The vast majority of waterproof clothing fabrics use laminated (film) materials, but there are also various treatments such as encapsulated fibers, tightly woven fabrics, and silicone treatments. This laminate is usually located in the inner layer of the clothing fabric, commonly referred to as the "waterproof membrane." The waterproof membrane is a composite clothing fabric created by bonding a thin film to other clothing fabric materials using an adhesive process. The clothing fabric itself is not waterproof. Therefore, when people wear waterproof clothing and get wet, water will seep into the garment, but the inner layer remains dry. This is because the waterproof membrane in the middle of the composite clothing fabric plays a role. However, clothing fabrics using this type of "waterproof membrane" are often suitable for woven hard-shell garments worn as outermost clothing. This limits the scope of application of this waterproof treatment; that is, it is not suitable for sportswear and casual clothing such as sweatshirts worn as innerwear.

[0005] As a result, while existing windbreakers offer satisfactory waterproof and windproof performance, their design is limited and they are generally only suitable as outerwear, resulting in clear limitations in usage scenarios. On the other hand, while hoodies, which are typically worn as innerwear, offer more diverse styles, their waterproof and windproof performance does not meet the warmth and protection needs of consumers in autumn and winter, thus restricting their usage scenarios and reducing consumer demand and desire to purchase them.

[0006] In summary, there is a functional need in the prior art to provide a way to improve the waterproof and windproof properties of knitted fabrics used in hoodies, thereby expanding the use cases of casual clothing that includes such knitted fabrics. This would allow consumers to use windproof and light rainproof hoodies as outerwear even in cold weather, making clothing combinations more personalized. Utility Model Content

[0007] Therefore, the purpose of this utility model is to provide a windproof and light rainproof fabric for sweatshirt knitwear and sweatshirts and sweatpants containing the same. This fabric maintains the required softness, fluffiness, and structured yet naturally draping properties of a sweatshirt knitwear fabric. The resulting sweatshirts or sweatpants are windproof and light rainproof, offering better warmth and protection for autumn and winter. They are adaptable to more life scenarios, allowing sweatshirts to be worn not just as innerwear, but also for both indoor and outdoor environments. This provides young people with a more convenient, casual, fashionable, and functional way to dress.

[0008] To address the technical problems existing in the prior art and realize the function of windproof and rainproof sweatshirts and sweatpants, this utility model provides a three-layer bonded knitted garment fabric with windproof and light rainproof functions. The three-layer bonded knitted garment fabric has good windproof and water-repellent functions, meeting the functional requirements of windproof and light rainproof sweatshirts and sweatpants.

[0009] To achieve the above-mentioned technical effects, the present invention adopts the following technical solution:

[0010] The purpose of this utility model is to provide a garment fabric, comprising a surface layer, a film layer, and a bottom layer, wherein the surface layer is the outermost knitted fabric and the bottom layer is the innermost knitted fabric, and the film layer extends between the surface layer and the bottom layer. The key feature is that either the surface layer or the bottom layer of the knitted fabric is treated with a water-repellent finishing process, so that the garment fabric has an air permeability of 0.10 mm / s according to GB / T 5453-1997 standard, and an air permeability of 0.31 mm / s after 5 washes; and a moisture permeability of 6600 g / (m³) according to GB / T 1207.2-2009 standard. 2 •24h); The water resistance rating tested according to GB / T4745-2012 standard is 3-4.

[0011] Compared with existing technologies, this utility model has at least the following beneficial effects: This utility model provides a three-layer bonded knitted garment fabric with windproof and light rainproof functions, exhibiting excellent windproof performance and water-repellent properties. Therefore, by adopting the technology of this utility model, consumers can be provided with a sweatshirt or sweatpants that are windproof and light rainproof, offering protection against cold winds and light rain, better warmth retention, and adaptability to more scenarios, breaking through the limitations of previous sweatshirts and sweatpants in adapting to a wider range of wearing occasions.

[0012] As a preferred aspect of this invention, either the outer layer or the inner layer can be knitted using a warp knitting plain weave or a weft knitting plain weave, wherein the needle density of the outer layer and the inner layer is not less than 40 needles / inch.

[0029] The present invention will be further described in detail below with reference to specific embodiments. The embodiments given are only for illustrating the present invention and are not intended to limit the scope of the present invention.

[0030] For consistency and convenience, directional adjectives may be used throughout this detailed description corresponding to the illustrated embodiments. Those skilled in the art will recognize that terms such as “above,” “below,” “upward,” “downward,” “top,” and “bottom” may be used descriptively with respect to the drawings without implying a limitation on the scope of the invention as defined by the claims. The term “horizontal” refers to a plane extending in both the longitudinal and transverse directions and perpendicular to the vertical direction.

[0031] refer to Figure 1 This diagram illustrates the structure of a clothing fabric with windproof, light rainproof, and heat-generating functions according to the present invention. The clothing fabric includes: a surface layer 101, a film layer 102, and a bottom layer 103. The surface layer is the outermost layer, the bottom layer is the innermost layer, and the film layer extends between the surface layer and the bottom layer. The surface layer and the bottom layer are lamb's wool knitted clothing fabrics, and the film layer is a TPU / PU film.

[0032] The top or bottom layer is made of warp knitting (needle density ≥ 40 stitches / inch) or weft knitting (needle density ≥ 40 stitches / inch), such as Figure 2 and Figure 3 As shown, the knitted garment fabric of the surface layer 101 is treated with a water-repellent finish before being bonded to the membrane layer 102. Currently, knitted plain weave garment fabrics are relatively easy to achieve a water-repellent effect when considering different weaving methods for garment fabrics.

[0033] Waterproofing agents for fabrics are classified into fluorinated and non-fluorinated types. Fluorinated waterproofing agents are fabric waterproofing agents containing fluorinated compounds, mainly divided into C4, C6, and C8 waterproofing agents. C8 waterproofing agents have been gradually phased out of the market due to environmental concerns, while the more commonly used C6 and C4 waterproofing agents have lower bioaccumulation and toxicity compared to C8 waterproofing agents.

[0034] Fluorine-free waterproofing agents, which are completely free of fluorocarbon resins, do not possess oil-repellent properties. However, they are not prone to deposition in biological bodies, are easily degraded, and are harmless to the human body. They come in various types and have excellent application value in the single-waterproofing finishing of garment fabrics. Fluorine-free waterproofing agents are environmentally friendly, high-performance textile auxiliaries. Their main characteristics are that they do not contain APEO (alkylphenol polyoxyethylene ether), PFOA (perfluorooctanoic acid), or PFOS (perfluorooctane sulfonic acid), making them harmless to the environment and human health. They possess excellent water-repellent and anti-siphon properties. Compared with existing fluorinated waterproofing agents, most fluorine-free waterproofing agents have a certain price advantage. They can be used for single-waterproofing finishing of garment fabrics, or as synergists / fillers in combination with fluorocarbon waterproofing agents to enhance the water and oil repellency of garment fabrics.

[0035] The water-repellent auxiliaries used in the surface layer garment fabric include fluorine-free water-repellent auxiliaries and C4 and C6 water-repellent auxiliaries. Preferably, the fluorine-free water-repellent auxiliaries used are commercially available from DuPont, USA, under the trade name DuPont Zelan R3, and the C4 and C6 water-repellent auxiliaries used are FCB028 type C6 water-repellent.

[0036] The waterproof layer sandwiched between the top and bottom layers is a membrane layer, composed of TPU or PU film. TPU film possesses high abrasion resistance, tear resistance, low-temperature resistance, and flexibility, while also exhibiting good elasticity and transparency. PU film offers good softness, elasticity, and transparency, but its abrasion resistance and tear resistance are inferior to TPU film. TPU film is widely used in clothing, footwear, packaging, and sporting goods, and can be used to make waterproof and breathable clothing, insoles, backpacks, etc. PU film is primarily used in the production of artificial leather, printing, and coatings, and can also be used to make waterproof materials, flooring, furniture, etc. Therefore, choosing TPU or PU material as the intermediate membrane layer can effectively improve the waterproof performance of clothing fabrics.

[0037] The top layer 101, membrane layer 102, and bottom layer 103 are sequentially bonded together with hot melt adhesive layers, ensuring a stable connection between the structural layers. Simultaneously, the hot melt adhesive layers are applied using a dot-lay method, minimizing the impact on the breathability of the garment fabric and ensuring good breathability. Through this composite fabric structure, the top layer 101 provides a certain degree of protection for the intermediate waterproof membrane layer 102.

[0038] After water-repellent treatment of cotton knitted garment fabrics and fleece composite garment fabrics, the bonding process parameters usually need to be adjusted when bonding the surface layer and the TPU film layer.

[0039] Waterproofing treatment will have the following impacts on the performance parameters of the bonding process.

[0040] 1. Adhesion strength: Water-repellent treatment may reduce the surface energy of the garment fabric, affecting the adhesion to the TPU film, resulting in a decrease in adhesion strength and making the composite garment fabric prone to delamination during use.

[0041] 2. Water resistance: Although the water-repellent treatment gives the surface a certain water-repellent effect, if the bonding area is not properly treated, water may enter from the edges or weak points, affecting the overall water resistance. In particular, when bonding at high temperatures, the water-repellent coating may be partially damaged, reducing the water resistance performance.

[0042] 3. Breathability: Water-repellent treatment and the TPU film itself can affect breathability. If the bonding process parameters are not appropriate, such as excessive pressure or high temperature, the pores of the clothing fabric may be further reduced or blocked, resulting in poor breathability.

[0043] Therefore, the following adjustments should be made to the wet process parameters during actual operation:

[0044] 1. Temperature: Appropriately increase the bonding temperature, generally 5-10℃ higher than the conventional bonding temperature, and control it between 140℃-160℃, so that the TPU film can better integrate with the water-repellent treated clothing fabric and improve the bonding effect. However, it should not be too high, otherwise it will damage the clothing fabric or cause the water-repellent coating to fail.

[0045] 2. Pressure: The pressure needs to be appropriately reduced by about 10% - 20%, and controlled between 0.25-0.4MPa to prevent the surface structure of the water-repellent clothing fabric from being damaged by excessive compression, while avoiding excessive pressure that could cause excessive deformation of the TPU film and affect its performance.

[0046] 3. Time: By reducing the speed of the laminating machine, the lamination time can be appropriately extended by about 10% to 30%, controlled at 15-20 meters per minute, allowing the TPU film and the clothing fabric more time for intermolecular interaction, thereby improving the bonding strength.

[0047] As a preferred technical solution of this utility model, in order to ensure better water repellency at the needle holes during the manufacturing process of the sweatshirt and sweatpants, adhesive strips are used inside the garment to seal the seams and joints of different pieces to ensure that water does not seep into the skin.

[0048] Compared with the prior art, the present invention has at least the following beneficial effects:

[0049] 1. This utility model provides a sweatshirt or sweatpants with windproof and light rainproof functions, which can resist cold wind and light rain, has better warmth retention, and can be adapted to more occasions, breaking through the limitations of previous sweatshirts and sweatpants to adapt to more wearing scenarios.

[0050] 2. This utility model provides a three-layer bonded knitted garment fabric with windproof and light rainproof functions, which has excellent windproof performance and water-repellent function.

[0051] This invention also conducts windproof and water-repellent tests on the clothing fabric with windproof and light rainproof functions made according to this invention to verify its windproof and water-repellent effects.

[0052] First, the windproof performance of the garment fabric was tested. The windproof performance of garment fabric is related to its air permeability. Air permeability refers to the ability of air to pass through a fabric, expressed as the rate at which airflow passes vertically through the sample under specified test area, pressure drop, and time conditions. The technical requirements for the windproof performance of the tested garment fabric are shown in Table 1.

[0053] Table 1

[0054]

[0055] The air permeability of the windproof and light rainproof clothing fabric described in this utility model was tested according to the method of GB / T5453-1997. In this test, products of the same style and color from the same order were considered as a batch, and one sample (2.0m × width) was randomly selected from each batch for testing. When sampling, care should be taken to ensure that the sample is representative as much as possible.

[0056] The results of the air permeability test are shown in Table 2.

[0057] Table 2

[0058]

[0059] The test results show that the clothing fabric with windproof and light rainproof functions described in this invention has extremely low breathability, thus exhibiting strong windproof performance. In retesting after multiple washes, the breathability of the fabric slightly increased, indicating a slight decrease in windproof performance. However, the breathability values ​​after washing show that the fabric still fully meets the windproof requirements for garments made from it. In summary, sweatshirts or sweatpants made from the aforementioned clothing fabric have strong windproof performance. Even after multiple washes, sweatshirts or sweatpants made from the clothing fabric described in this invention still maintain strong windproof performance and can still meet the user's windproof needs.

[0060] Secondly, the water-repellent properties of the clothing fabric with windproof and light rainproof functions according to this utility model were tested. The water-repellent properties of the clothing fabric are related to its water repellency rating. The water repellency rating of the clothing fabric is the degree to which the fabric surface resists being wetted by water. The requirements for the water-repellent rating of clothing fabrics with water-repellent functions are shown in Table 3.

[0061] Table 3

[0062]

[0063] The water repellency grade of the fabric for clothing with the functions of wind prevention and light rain prevention described in this utility model shall be implemented in accordance with the provisions of GB / T4745-2012. In this test, the same product composition produced from the same raw materials and with the same production process is taken as an inspection batch. Three samples are randomly selected from each batch for inspection. According to the product design requirements, only the parts of the product with this function are evaluated. If all the tested samples meet the requirements, the batch of products is judged to be qualified. If one sample (or more) does not meet the requirements, double sampling is carried out for re-inspection of the unqualified items, and the judgment is made according to the re-inspection results.

[0064] Testing equipment and materials: Spraying device, consisting of a funnel with a diameter of (150±5)mm vertically clamped and a metal nozzle. The funnel and the nozzle are connected by a rubber hose with a 10mm diameter. The distance from the top of the funnel to the bottom of the nozzle is (195±10)mm; Metal nozzle, the metal nozzle has a convex circular surface, and 19 holes with a diameter of (0.86±0.05)mm are evenly distributed on the surface. After (250±2)mL of water is injected into the funnel, its continuous spraying time should be between 25s and 30s; Specimen holder, which consists of two mutually fitting nylon rings or metal rings. The outer diameter of the inner ring is (155±5)mm, and the inner diameter of the outer ring is (155±5)mm. The specimen can be firmly clamped; The test water is distilled water or deionized water, and the temperature is (20±2)℃.

[0065] During the test, the holder is placed on a fixed base at an angle of 45° to the horizontal, and the center of the specimen is located (150±2)mm below the center of the nozzle surface.

[0066] When testing the water repellency performance of the fabric for clothing, the specimen is installed on the annular holder, keeping the holder at an angle of 45° to the horizontal, and the center position of the specimen is at a certain distance below the nozzle; A certain amount of distilled water or deionized water is sprayed on the specimen. After spraying, the water repellency grade of the fabric is determined by comparing the appearance of the specimen with the description and pictures of the water contact phenomenon.

[0067] Specifically, the test steps are as follows:

[0068] After the specimen is conditioned, it is clamped with the holder and placed on the support. During the test, the front side of the specimen faces up, and the warp or length direction of the fabric is parallel to the water flow direction;

[0069] Pour 200mL of test water quickly and smoothly into the funnel;

[0070] After the spraying stops, immediately remove the clamp holding the sample, so that the fabric is almost horizontal with the right side facing down. Then tap the clamp once against a solid hard object, rotate the clamp horizontally 180° and tap the clamp once again.

[0071] After the tapping is completed, the degree of wetting of the sample front side on the holder is immediately rated according to the description of water contamination in Table 4.

[0072] Repeat the above steps to measure the remaining sample.

[0073] Table 4

[0074]

[0075] The test results of the water-repellent properties of the clothing fabric with windproof and light rainproof functions according to this utility model are shown in Table 5.

[0076] Table 5

[0077]

[0078] The test results show that the clothing fabric with windproof and light rainproof functions described in this invention has high water-repellent performance. Its water-repellent performance remains largely unchanged before washing and after five washes, consistently at level 3-4, which meets the light rain and water-repellent effect described in this invention. Furthermore, the moisture permeability of the clothing fabric with windproof and light rainproof functions described in this invention is 6.60 × 10⁻⁶ before washing. 3 g / (m 2 (∙24h), after 5 washes, the moisture permeability of the garment fabric is 2 to 3 times that of the garment fabric before washing. In general, sweatshirts or sweatpants made from the above-mentioned garment fabric have strong water-repellent and moisture-permeable properties. After multiple washes, the water-repellent properties of sweatshirts or sweatpants made from the garment fabric of this invention remain unchanged, while their moisture permeability is enhanced. This allows the wearer to experience a comfortable wearing experience while remaining water-repellent, as the high moisture permeability allows sweat to be conducted to the outside in the form of water vapor through the fabric. As a preferred technical solution of this invention, the moisture permeability of the membrane layer in the garment fabric, namely the TPU membrane layer or the PU membrane layer, is not less than 3000g / (m²). 2 •24h).
