Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a method for producing pom-pom fabric and the pom-pom fabric itself. Background Technology

[0002] With advancements in technology and increasing consumer demand for personalization, the fabric market is placing higher demands on the comfort, softness, durability, and aesthetic design of textiles. In traditional fabric production, appropriate yarns and processes are typically selected based on different functional requirements. However, while meeting these basic functions, it is often difficult to simultaneously achieve optimal softness, comfort, and aesthetic appeal. This issue is particularly prominent in the production of high-end apparel, home textiles, and certain specialty fabrics.

[0003] Currently, most fabric production technologies on the market focus on fiber strength and durability, but they often have limitations in terms of softness, drape, and the diversity of fabric design. Although some technologies improve the softness and feel of fabrics through different yarn combinations, weave structures, and sizing processes, these solutions still cannot find an ideal balance between softness and design. Furthermore, traditional weaving techniques are mainly suitable for simple structures, making it difficult to create fabrics with unique styles and good three-dimensionality. The appearance of the fabrics often appears monotonous, lacking uniqueness and personalization, and failing to meet consumers' demands for diverse and high-quality fabrics.

[0004] While existing sizing techniques have made attempts to improve softness and hand feel, relying solely on a single sizing method or yarn treatment often fails to achieve the desired balance between enhanced comfort and improved fabric strength and durability. Furthermore, conventional finishing processes primarily focus on cleaning and improving fabric durability, offering limited effectiveness in enhancing tactile smoothness and visual richness. Limited means of enhancing fabric design result in bland and uninspiring designs that fail to attract and guide consumers, thus diminishing the overall experience. Clearly, current technology has not adequately addressed the challenge of simultaneously improving fabric softness, comfort, and visual uniqueness, particularly in the high-end and personalized market, where this demand remains unmet. Therefore, finding innovative combinations of yarn, sizing, weaving, and finishing processes to meet increasingly diverse consumer needs has become a pressing technical challenge for the textile industry.

[0005] Currently, although various pom-pom fabrics and their manufacturing methods exist in the existing technology, careful analysis reveals that they generally suffer from one or more of the following limitations: First, most methods focus on napping or brushing in the finishing stage to create a velvety feel. The resulting velvety surface is uniform but lacks a three-dimensional and regular pattern effect, and the feel and appearance are highly homogenized. Second, some methods that use weaving to form pom-poms often employ uniform and high-level sizing treatment on all warp yarns or resin hardening treatment on the yarns forming the pom-poms to ensure smooth weaving and pom-pom fixation. This results in a stiff and itchy feel to the pom-poms, sacrificing the most important aspect of the fabric: comfort. Third, although some patents mention multiple yarn combinations, they do not perform differentiated pretreatment based on their fundamental characteristics. Their weaving devices are also unable to handle the tension and shrinkage mismatch caused by yarns with different properties, resulting in low production efficiency and numerous fabric defects.

[0006] Therefore, existing technologies do not provide a comprehensive solution that can simultaneously achieve "regular three-dimensional pom-pom appearance", "soft and fluffy pom-pom itself", and "high-efficiency and high-quality weaving of the entire fabric". Summary of the Invention

[0007] To address the technical challenge of balancing softness and style in pom-pom fabrics, this invention provides a method for producing pom-pom fabrics and the fabric itself. Through a combination of processes including "differentiated pretreatment, multi-axis collaborative weaving, precise pattern cutting, and flexible finishing," the inherent technological contradiction between the three-dimensional shape of pom-poms and their soft touch is effectively resolved. The resulting fabric not only possesses a soft feel but also exhibits unique stylistic characteristics.

[0008] The technical solution of this invention is as follows: In a first aspect, the present invention provides a method for producing pom-pom fabric, comprising the following steps: S1. The warp yarns are made of three types of yarn: M40s, CD32s / 2 and R22s / 3. M40s yarn is treated with normal sizing, CD32s / 2 yarn is treated with pre-wet low sizing, and R22s / 3 yarn is treated with no sizing and water rinsing. M40s yarn has many interlacing points in the fabric structure and requires good abrasion resistance, so conventional sizing processes and routes are used. Meanwhile, this invention addresses the issue of CD32s / 2 yarn having many interlacing points in the fabric structure diagram and relatively small warp shrinkage. In addition, the parallel arrangement of double yarns further reduces the weaving shrinkage rate. Therefore, a pre-wetting low sizing process route is adopted to achieve weaveability requirements with minimal sizing film coverage, leaving maximum room for subsequent hand feel. Furthermore, this invention also addresses the issue of R22s / 3 yarn having fewer interlacing points in the fabric structure and good abrasion resistance of the ply yarn itself. It also considers the three-dimensionality and fullness of the pom-poms in subsequent processing. In particular, in order to ultimately give the pom-poms a natural soft and fluffy touch, rather than a hand feel hardened by sizing, an unsizing and water-washing process is adopted. This treatment method breaks through the traditional technical requirement that warp yarns must be sized.

[0009] S2. The three types of yarns processed in step S1 are wound onto three independent warp beams and woven together with the weft yarns to form a fabric with floating threads.

[0010] This invention achieves independent control and coordinated weaving of three yarns with distinct properties through a three-beam weaving device. This allows the weaving process to create diverse structural patterns in the fabric, improving not only its aesthetics but also its comfort and uniqueness. Through this process, the fabric not only possesses strong plasticity but also exhibits rich visual effects.

[0011] This invention employs a multi-layered interlacing structure and various yarn combinations to enhance the fabric's uniqueness and comfort. In this structure, the yarn interlacing method is precisely arranged according to the fabric's functional and aesthetic requirements. Each layer of the fabric has a different weaving method, and the desired physical performance requirements are achieved by precisely controlling the density of the warp and weft yarns and the arrangement of interlacing points. Simultaneously, this invention utilizes a triaxial weaving process, which employs three axes simultaneously, each axis responsible for a different yarn combination. Through the alternating movement of the three axes, multi-dimensional weaving in the longitudinal, transverse, and three-dimensional directions is achieved. This axis-separated design is key to achieving differentiated sizing effects. Furthermore, the triaxial weaving process creates a unique pom-pom pattern effect within the fabric while ensuring overall softness and breathability.

[0012] S3. The floating threads are cut through the flower cutting process, and then the fabric undergoes desizing, scouring, washing and softening processes to obtain the pom-pom fabric.

[0013] This invention utilizes a cutting process, employing R22s / 3 yarn with a fixed float length to create a unique pom-pom pattern. This effect is achieved through the aforementioned unsizing treatment, ensuring the pom-pom fibers are not bound by sizing, resulting in a naturally fluffy texture after cutting, while maintaining the overall softness and breathability of the fabric. A washing process effectively removes surface fuzz from the fibers, making the pom-pom structure clearer and fuller. Furthermore, a softening finishing process significantly improves the fabric's hand feel, giving it excellent smoothness and fluffiness, while also enhancing its antistatic and abrasion resistance, thus improving overall wearing comfort. After softening and washing, a regular, soft pom-pom effect forms on the fabric surface, making it visually and tactilely softer and more comfortable, greatly improving the overall quality of the fabric.

[0014] Furthermore, in step S1, the unsizing and water-washing process of the R22s / 3 yarn is as follows: the yarn is passed through a hot water bath at a temperature of 85-95℃, fully immersed by the immersion roller, and then pressed and dehydrated by a first pressure roller with a pressure set to 1.5KN and a second pressure roller with a pressure set to 3.0KN in sequence, and finally dried.

[0015] Furthermore, in step S1, the pre-wetting and low sizing process of the CD32s / 2 yarn is as follows: the yarn is first pre-wetted in a hot water bath at 85-95℃, and after pressing, its moisture regain is controlled at about 60%. Then, it is pre-dried to reduce the moisture regain to below 17%, and then it enters the sizing bath for sizing. Finally, the sizing rate is controlled within the range of 5.5%-6%.

[0016] Furthermore, in the pre-wetting low sizing process of the CD32s / 2 yarn, in order to compensate for the moisture brought in by the yarn, the solid content of the sizing solution is 9% and the viscosity is 7″.

[0017] Furthermore, in step S1, the conventional sizing process for the M40s single yarn is as follows: a mixed sizing agent of starch and polyvinyl alcohol (PVA) is used, the viscosity of the sizing agent is controlled at 6-10 seconds, and the sizing rate is controlled at 9%-10%.

[0018] Furthermore, in step S2, the three types of warp yarns treated with different sizing processes are wound onto three independent warp beams. The first beam uses M40s yarn, the second beam uses CD32s / 2 yarn, and the third beam uses R22s / 3 yarn to ensure the visual richness and tactile comfort of the fabric.

[0019] Furthermore, in step S2, during the reed threading process of weaving, according to the fabric structure design, CD32s / 2 yarn is threaded into the 5th, 6th, 7th and 8th reed teeth, R22s / 3 yarn (using large-eye heddle yarn) is threaded into the 3rd and 4th reed teeth, and M40s yarn is threaded into the 1st and 2nd reed teeth.

[0020] Furthermore, in step S3, the washing process employs enzyme washing, with the following conditions: using 1.0%-3.0% cellulase by weight of the fabric, in a water bath at pH 4.5-5.5 and a temperature of 50-55℃, at a liquor ratio of 1:10-15 for 45-60 minutes. This invention utilizes a specialized enzyme washing process, using cellulase to gently treat the fabric surface, effectively removing fuzz from the fiber surface and making the pom-pom structure clearer and fuller. This treatment also fully relaxes and softens the fibers, further enhancing the fabric's softness, while giving the pom-poms a more three-dimensional shape. Furthermore, controlling the temperature at 50-55℃ effectively avoids damage to the fabric fibers caused by excessive heat; the 45-60 minute treatment time ensures the uniformity of the pom-pom effect without causing fiber breakage.

[0021] Furthermore, in step S3, the softening finishing process involves treating the fabric with a hydrophilic softener working solution at a concentration of 30-60 g / L using a two-dip, two-paddle method, controlling the paddle ratio at 65%, followed by drying at 100°C. Treatment with a hydrophilic softener can form a micron-level soft protective layer on the fiber surface.

[0022] Secondly, the present invention also provides a pom-pom fabric, wherein the fabric surface has regularly distributed three-dimensional pom-poms, has a soft and fluffy feel, a warp breaking strength ≥420N, a weft breaking strength ≥380N, abrasion resistance ≥15000 cycles, a pilling grade of 4-5, a pom-pom shedding rate ≤3.5%, a dimensional change rate ≤±2.5%, and a softness ≤3.5cm.

[0023] The beneficial effects of this invention are as follows: This invention proposes a full-chain solution of "differentiated pretreatment - multi-axis collaborative weaving - precise pattern cutting - flexible finishing". By using three types of yarns, M40s, CD32s / 2 and R22s / 3, as warp yarns and implementing three differentiated sizing treatments, namely conventional sizing, pre-wet low sizing and no sizing and water washing, the softness and strength of the yarns can be precisely controlled. This differentiated sizing strategy is a special solution designed for the different roles and contributions of each yarn in the fabric, rather than a conventional choice.

[0024] Furthermore, through the transformation of triaxial technology, the weaving process breaks through traditional limitations, achieving complex and special structural patterns, greatly enriching the visual effects and plasticity of the fabric. Subsequently, a shearing process is used to cut the floats to a fixed length, enhancing the surface smoothness and shape control. Since the R22s / 3 yarn has not undergone sizing and hardening, the resulting pom-poms have inherent softness. After washing and softening treatment, a regular and soft pom-pom effect is finally formed.

[0025] Compared with existing technologies, this invention effectively solves the contradiction between softness and style effect in the traditional fabric production process. In particular, it breaks through the technical bottleneck of the difficulty in coordinating high wear-resistant weaving requirements with an extremely soft hand feel, and fixed three-dimensional pom-pom structure with fluffy pom-pom touch in a single fabric system. The fabric produced in this way not only has a soft touch, but also presents unique style characteristics. It is suitable for high-end clothing, home textiles and various special-purpose fields, and has broad application prospects and market value. Attached Figure Description

Obviously, for those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0028] Figure 2 This is a schematic diagram of the structure of the three axes in Embodiment 1 of the present invention.

[0029] Figure 3 This is a rendering of the finished fabric product according to Embodiment 1 of the present invention. Detailed Implementation

[0030] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0031] Example 1 (1) Raw material preparation: The warp yarn is selected from Modal fiber M40s single yarn + carded 32s / 2 double yarn + viscose (or viscose) 22s / 3 triple yarn, and the weft yarn is selected from Modal fiber M40s single yarn. The fabric width is 65 inches and the warp and weft density is 74×58 inches.

[0032] (2) Warping: R22s / 3 yarn warp beams can wind 221 yarns, requiring 1 beam; CD32s / 2 yarn warp beams can wind 771 yarns, requiring 1 beam; M40s yarn warp beams require a total of 3840 yarns. Each warp beam can wind 768 yarns, requiring a total of five warp beams. The warping speed is set to 650m / min.

[0033] (3) Sizing: For M40s yarn, the normal sizing process and route are adopted, and the "high speed, high pressure, low sizing" process route is adopted. In order to ensure the uniform arrangement of yarn, a higher wet tension control approach is adopted. Microwave starch: 62.5kg, high performance starch: 15kg, sizing volume: 0.8m³, solid content: 8.7g / 100ml, viscosity: 6-7 seconds, sizing temperature controlled at 90℃ and above, and the sizing rate is expected to be 9%-9.5%.

[0034] For CD32s / 2 yarn, a pre-wetting low-sizing process is adopted. In the workshop sizing process, a axially oriented sizing pan is used as the water tank, with the water temperature controlled at approximately 90℃. The yarn must pass through immersion rollers, ensuring the sizing pump in the water tank can circulate normally. The first pressure in the water tank is set to 1.5KN, and the second pressure is set to 3.0KN. The moisture regain upon exiting the water tank is controlled at approximately 60%. After exiting the first sizing tank, the yarn passes through a set of cylinders, with the cylinder temperature controlled at 100℃. The moisture regain of the yarn after leaving the cylinders should be controlled below 17%. Then, the yarn enters the second sizing tank. Due to the higher moisture regain, more moisture is carried into the second sizing tank. The sizing solution is easily diluted, and its viscosity (or viscosity) decreases. Therefore, the solid content of the sizing solution during yarn preparation is 9% compared to the sizing solution of similar varieties, which is 2 percentage points higher than the standard process. The viscosity is 7″, which is 30% higher than the standard process of 5.4″. Due to the change in the yarn guide route, guide rollers are added to introduce the yarn into the sizing pot. The pressure setting is the same as normal. In terms of tension settings in each zone, due to the increase in the length of the wet zone, in order to avoid excessive tension, which would cause increased elongation and high yarn elongation reduction rate, the tension in each zone needs to be controlled to be smaller. The waxing roller is adjusted from the original 0.5 rpm to 1.0 rpm.

[0035] For R22s / 3 yarn, a non-sizing and water-cooling process is not used. First, prepare the sizing in the workshop, using a shaft-side sizing pan as the water tank, with the water temperature controlled at approximately 90℃. The yarn needs to pass through immersion rollers, ensuring the pump in the water tank can circulate normally; the first pressure in the water tank is set to 1.5KN, and the second pressure is set to 3.0KN. When exiting the water tank, the moisture regain should be strictly controlled at around 60%.

[0036] Regarding equipment, the warp beams are calibrated, and the brake bands and cylinders are maintained to ensure uniform unwinding tension. The cylinder chain is tightened to prevent improper tension and slippage, resulting in smoother operation of the sizing machine.

[0037] Based on the properties of the sizing agents, the fabric requirements are to maximize strength while minimizing fuzz and preventing unclear opening. Utilizing the advantages of both phosphate starch and potato starch, a mixture of the two sizing agents is used. The mixture consists of 50 kg of phosphate starch, 25 kg of potato starch, and 12.5 kg of acrylate, with a sizing volume of 0.8 m³ and a solid content of 8.4 g / 100 ml. The expected sizing rate is 9%–10%.

[0038] (3) Threading the reed: The reed number and length are 59×2385, the reed width is 68.14", the number of selvage yarns is 36×2, the number of heddle frames is 8×1, the selvage weave is 1 / 1, and the yarn is arranged according to the different structures in the weave diagram when threading the reed. CD32s / 2 yarn is threaded in the 5th, 6th, 7th and 8th warps, R22s / 3 yarn is threaded in the 3rd and 4th warps, and M40s yarn is threaded in the 1st and 2nd warps.

[0039] (4) Weaving: Weaving adopts a three-axis weaving process route. The first axis uses M40s yarn, the second axis uses CD32s / 2 yarn, and the third axis uses R22s / 3 yarn.

[0040] Regarding the adjustment of weaving equipment: Adjust the warp position lines appropriately to increase fabric stability and reduce weft insertion force. The back beam position is No. 4-2, the pedal type is a multi-arm pedal, the warp stop position is adjusted according to the back beam, the fabric width on the machine is 65", the shedding time is 290°, the machine speed is above 600 rpm, and the weft density is set to 59 yarns / inch.

[0041] (5) Cutting: Cut the R22s / 3 yarn to a fixed float length to create a pom-pom pattern effect.

[0042] (6) Desizing: Since the M40s and CD32s / 2 yarns have been sized, the greige fabric needs to be desized first. Use 8g / L desizing softener RBE and 4g / L strong refining agent CP-6L, at a temperature of 60-65℃, for 40-60 minutes to fully remove the sizing agent and provide a uniform penetration base for subsequent processing.

[0043] (7) Scouring: After desizing, the fabric enters the scouring process to remove waxes, pectin and other co-existing substances from the fibers. 20 g / L soda ash, 8 g / L sodium silicate, 3 g / L chelating stabilizer MEX-C and 40 g / L hydrogen peroxide are used to treat the fibers at 100°C for 60-90 minutes to fully purify them.

[0044] (8) Enzyme Washing: The scouring and boiling fabric is treated with enzyme washing. Cellulase is used for treatment, with an enzyme dosage of 1.0-2.0% (owf), pH value controlled at 4.5-5.5, temperature at 50-55℃, treatment time at 45-60 minutes, and a liquor ratio of 1:10-15. By precisely controlling the enzyme washing process parameters, the yarn tails left on the fabric surface are fully expanded and fluffed up, while avoiding damage to the main body of the fabric. This process not only further softens the fibers, but is also a key step in fully displaying and solidifying the three-dimensional shape of the pom-poms.

[0045] (9) Softening Finishing: The washed fabric undergoes a final softening treatment to achieve an extremely soft touch. The treated fabric is immersed in the hydrophilic softener SYNICO-6811, with the solution concentration controlled between 30-60 g / L; the fabric is then subjected to a two-dip, two-ply treatment, with the ply rate controlled at 65%; after the plying is completed, it is dried at 100°C. By using a softener for finishing, a durable hydrophilic soft film is formed on the fiber surface, greatly improving the fabric's skin-friendly feel and comfort, while keeping the fluffy balls in a fluffy state.

[0046] Comparative Example 1 All process parameters for raw material preparation, warping, reed threading, weaving, desizing, scouring, enzyme washing, and softening finishing in Comparative Example 1 are completely consistent with those in Example 1. The only difference is that the three yarns did not use differentiated treatment processes. M40s yarn, CD32s / 2 yarn, and R22s / 3 yarn were all treated using the conventional sizing process for M40s yarn in Example 1.

[0047] Comparative Example 2 Comparative Example 2: The pom-pom fabric is a typical commercially available product, manufactured in Shaoxing, with specifications of 75D*75D 150cm and 75g / ㎡.

[0048] Performance testing: Test 1: The warp and weft breaking strengths of the pom-pom fabrics of Example 1 and Comparative Examples 1-2 of the present invention were tested in accordance with GB / T 3923.1-2013. Test 2: The abrasion resistance of the pom-pom fabrics of Example 1 and Comparative Examples 1-2 of the present invention was tested according to GB / T 21196.2-2022; Test 3: The pilling grade of the pom-pom fabrics of Example 1 and Comparative Examples 1-2 of the present invention was tested according to GB / T 4802.1-2021; Test 4: The pom-pom shedding rate of the pom-pom fabrics of Example 1 and Comparative Examples 1-2 of the present invention was tested according to GB / T 4802.2-2015; Test 5: The dimensional change rate of the pom-pom fabrics of Example 1 and Comparative Examples 1-2 of the present invention was tested according to GB / T 8628-2013; Test 6: The softness of the pom-pom fabrics of Example 1 and Comparative Examples 1-2 of the present invention was tested in accordance with GB / T 18318.1-2022.

[0049] The specific test items and performance test results are shown in Table 1: Table 1. Comprehensive performance test data of pom-pom fabrics in Example 1 and Comparative Examples 1-2 of the present invention

[0050] As can be seen from the data analysis in Table 1, Embodiment 1 of the present invention is significantly superior to Comparative Example 1 and Comparative Example 2 in many key performance indicators.

[0051] In terms of physical and mechanical properties, the warp and weft breaking strengths of Example 1 were higher than those of the comparative sample, indicating that the overall strength of the fabric was not reduced due to the formation of the pom-pom structure even with the introduction of unsized warp yarns. This demonstrates that differentiated sizing treatment can maintain the fabric's mechanical properties while ensuring weaving stability. Example 1 also exhibited higher levels of abrasion resistance and pilling resistance, indicating a stable pom-pom structure and good fiber bonding.

[0052] Regarding appearance retention, the pom-pom shedding rate of Example 1 was significantly lower than that of Comparative Examples 1 and 2, indicating that through the synergistic effect of non-sizing and water treatment combined with trimming, washing, and softening finishing, the pom-poms not only possess good three-dimensional morphology but also exhibit high structural stability. Furthermore, Example 1 showed a smaller dimensional change rate, indicating better dimensional stability during post-finishing and use.

[0053] In terms of comfort performance, the softness test value of Example 1 is significantly better than that of the comparative example, further verifying that the unsized pom-pom yarn can naturally fluff up and unfold after being cut, thereby effectively improving the overall soft touch of the fabric.

[0054] In summary, the differentiated sizing and finishing processes used in this invention achieve synergistic effects in multiple performance aspects, resulting in a significant improvement in the overall performance of the prepared pom-pom fabric.

[0055] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, the present invention is not limited thereto. Various equivalent modifications or substitutions can be made to the embodiments of the present invention by those skilled in the art without departing from the spirit and essence of the invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be covered within the protection scope of the present invention.
