Description

Technical Field

[0001] The invention relates to the technical field of curtain fabrics, and in particular to a high-quality oversized transparent roller blind fabric and a preparation method thereof. Background Art

[0002] In the field of architecture and home decoration, roller blind fabrics are widely used in curtains, sunshades and other products. With the diversification of modern architectural design and the improvement of people's requirements for the quality of living environment, the demand for large-sized windows and translucent roller blinds is increasing. Especially in commercial spaces, high-end residences, offices and other environments, the requirements for curtains are no longer limited to basic functions such as sunshade and light blocking, but pay more attention to their aesthetics, light transmittance and durability.

[0003] However, existing dyed large-size light-transmitting curtain fabrics face a number of technical challenges during the production process, mainly including:

[0004] 1. Fabric surface network pattern problem: This problem affects the appearance quality and uniformity of the fabric.

[0005] 2. Point splitting problem: During the fabric processing, especially in the pre-processing stage of fabric refining, point splitting often occurs, affecting the overall quality of the fabric.

[0006] 3. Wrinkle problem during dyeing process: During the dyeing process, the fabric is prone to wrinkles, affecting the aesthetics of the final product.

[0007] 4. Crack print problem: This is another common quality problem that seriously affects the appearance and durability of the fabric.

[0008] The existence of these problems seriously affects the quality and performance of large-sized transparent curtain fabrics, making it difficult to find products that truly meet high-end needs on the market. Therefore, developing a method for preparing large-sized transparent roller blind fabrics with zero appearance defects that can effectively solve these problems has become a technical problem that needs to be solved urgently in the industry.

[0009] At present, there is no perfect solution on the market to overcome these technical obstacles at the same time. Therefore, developing a new technical solution to solve the problems of fabric surface network pattern, spot splitting, wrinkle and crack marks during dyeing process is of great significance and value for improving the quality and performance of large-size light-transmitting curtain fabrics. Summary of the invention

[0010] In view of the technical problems existing in the above-mentioned prior art, the purpose of the present invention is to propose a high-quality oversized transparent roller blind fabric and a preparation method thereof, which uses selected high-strength 600D polyester composite yarn as raw material, combined with advanced weaving technology and sophisticated process design, to ensure that the fabric has significantly improved light transmittance, stability and aesthetics. In addition, through specific heat treatment and dyeing processes, the defects of the fabric in the production process are successfully eliminated, ensuring that the final product meets the highest industry standards, thereby meeting the needs of the high-end market.

[0011] The technical solution adopted by the present invention to solve its technical problem is:

[0012] A method for manufacturing high-quality oversized transparent roller blind fabric, characterized in that the method comprises the following steps:

[0013] S1. Yarn selection:

[0014] The warp yarn is 600D polyester composite yarn, which is composed of two polyester low-elastic network yarns with S twist and Z twist respectively, and the single yarn density is 300D;

[0015] The weft yarn is a single 600D micro-mesh low-elastic network yarn;

[0016] S2. Weaving of grey cloth:

[0017] The warp yarn and weft yarn selected in step S1 are used, and the fabric structure is 1 / 1 plain weave, and the grey fabric of the transparent roller blind fabric is woven on a wide-width loom, and the light transmittance of the transparent roller blind is accurately controlled by designing the density of the warp and weft yarns and the thickness of the warp and weft yarns, so as to meet the requirements of different places for transparent effects;

[0018] S3, Pre-setting processing:

[0019] The grey cloth is pre-shaped by using a hot air stenter setting machine, so that the grey cloth is evenly dried and the residual internal stress in the weaving process is also dissipated accordingly, so that the grey cloth can achieve a certain dimensional stability, ensuring that the grey cloth shrinks evenly during the next stage of high-temperature and high-pressure overflow cylinder dyeing to avoid cylinder wrinkles and cracks on the cloth surface; wherein, the temperature of the hot air stenter setting machine during the pre-shaped treatment is set to 160°C, the speed is 50M / min, and zero overfeed;

[0020] S4, cloth refining treatment:

[0021] The grey cloth is smelted by using a high-temperature and high-pressure overflow smelting machine, a specific smelting auxiliary formula and process parameters, so that the network points of the warp and weft yarns can be effectively untied to maintain a fluffy and full state, which can ensure uniform coloring during the dyeing process and avoid the occurrence of quality problems such as color spots, cracks, and dirt during the dyeing process;

[0022] The cloth refining auxiliary agent is prepared by mixing 12 to 15 parts of liquid alkali, 8 to 10 parts of hydrogen peroxide, 3 to 5 parts of oil remover, and 3 to 5 parts of anti-wrinkle agent in the bath.

[0023] The process parameters in the cloth smelting treatment are set as follows: the heating and cooling curve is: heating to 120°C at 1°C / min, keeping warm for 20 minutes, then cooling to 80°C at 1.2°C / min, the main pump speed is 1200-1250r / min, and the cycle seconds are controlled within 120s;

[0024] S5. Dyeing treatment:

[0025] The grey cloth is dyed by a high temperature and high pressure overflow dyeing machine to obtain colored cloth;

[0026] The nozzle size of the dyeing machine is 100mm, and the nozzle gap is 3 to 4 turns to ensure a certain water flow rate, so that the rope-shaped grey fabric changes shape when passing through the nozzle, and wrinkles are not easy to occur;

[0027] During the dyeing process, the temperature rise curve is increased to 130°C at 1°C / min, and the temperature is kept at this temperature for 30 minutes. The speed of the main pump of the dyeing equipment is set to 1200-1250r / min to ensure that the circulation seconds of the grey cloth in the dyeing tank are controlled within 100s-120s, reduce the accumulation time of the grey cloth, and avoid wrinkles during the dyeing process. At the same time, the running speed of the grey cloth and the force between the grey cloth and the dye solution are effectively controlled to avoid problems such as the grey cloth being torn.

[0028] S6. Re-determination processing:

[0029] A hot air stentering machine is used to stenter and set the colored cloth so that the cloth surface meets the set specification requirements after setting;

[0030] Among them, the setting temperature of the hot air stenter setting machine is 190°C, the speed is 40M / min, and the cold air frequency is 55-60HZ; the speed cannot be too fast during the re-setting process, otherwise it will affect the shrinkage and dimensional stability of the colored cloth, thereby affecting the flatness and appearance style of the finished coated product.

[0031] S7, double-sided scraping treatment:

[0032] The colored fabric after the fixation treatment is scraped, pre-baked, baked and cooled on the front and back sides of the fabric using a scraping device, so that a uniform and transparent film structure is formed at the interweaving of the warp and weft yarns of the fabric, thereby obtaining a transparent roller blind fabric;

[0033] The scraping slurry used in the double-sided scraping treatment is prepared by mixing and stirring 10 to 15 parts of polyurethane emulsion, 30 to 35 parts of acrylic emulsion, 8 to 10 parts of thickener, 5 to 10 parts of environmentally friendly cross-linking agent and 200 to 250 parts of deionized water by weight.

[0034] Through double-sided sizing treatment, a uniform and transparent membrane structure can be formed at the interweaving of the warp and weft yarns of the fabric, which can effectively filter out a part of the stronger sunlight by absorption or reflection. At the same time, the membrane structure also plays a very important role in the structural stability and stiffness of the fabric.

[0035] A high-quality oversized transparent roller blind fabric, characterized in that it is made by adopting the above-mentioned manufacturing method.

[0036] The beneficial effects of the present invention are:

[0037] 1. Significant improvement in appearance quality: Through the precise selection and design of the twist direction, thickness and density of the warp and weft yarns, the network pattern problem on the surface of the fabric is successfully eliminated, the uniformity and aesthetics of the fabric are improved, and the appearance requirements of the roller blind fabrics in the high-end market are ensured.

[0038] 2. Stable light transmittance and uniformity: The use of 600D polyester composite yarn combined with advanced weaving technology makes the fabric have excellent light transmittance, while maintaining the stability and dimensional accuracy of the fabric to meet the light transmittance requirements of different places.

[0039] 3. Complete elimination of process defects: Through specially set cloth refining auxiliary agent formula and dyeing process, common quality problems such as point splitting, wrinkle printing, crack printing in the production process are effectively solved to ensure the surface flatness and consistency of the product.

[0040] 4. Multiple functionality of membrane structure: A transparent membrane structure is formed at the interweaving of the yarns through a double-sided scraping process, which can not only filter and reflect part of the strong light, meeting the requirements of being transparent but not porous and airtight, but also the membrane structure enhances the stability and stiffness of the fabric, extending the service life of the fabric.

[0041] Overall, this technical solution provides a roller blind fabric with high light transmittance, no appearance defects, and excellent performance in strong light environments, which is suitable for high-end commercial and residential environments. BRIEF DESCRIPTION OF THE DRAWINGS

[0104] Technical effect demonstration

[0105] Solution to the network pattern problem: Through the precise design of the twist direction and thickness of the warp and weft yarns, this solution effectively avoids the network pattern problem common in the weaving process of existing large-size roller blind fabrics. Experimental data shows that compared with fabrics without special design, the network pattern defects of fabrics using this technology are reduced by 85%, and the surface uniformity and smoothness of the fabric are significantly improved.

[0106] Solution to the point split problem: During the smelting process, the specially designed auxiliary formula completely unravels the network points of the warp and weft yarns, avoiding the point split phenomenon. Comparative experiments show that the point splitting rate of fabrics without this smelting treatment is 30%, while the point splitting rate of fabrics after this treatment is reduced to less than 3%.

[0107] Elimination of wrinkle and crack marks: Through optimized dyeing process and reset process, especially controlling nozzle size, heating curve and cycle time during dyeing process, wrinkle and crack marks are effectively eliminated. Experimental comparison shows that the wrinkle defect rate of fabrics without optimized dyeing process is as high as 25%, while the fabrics treated by this solution are basically free of wrinkles and crack marks, and quality problems are reduced by more than 90%.

[0108] The improvement of the membrane structure: The uniform transparent membrane structure formed after double-sided slurry treatment not only enhances the aesthetics of the fabric, but also significantly improves the light transmittance and stiffness of the fabric. Experimental tests show that the light transmittance of the fabric treated with the membrane structure is increased by 12% under strong light, and the strength and durability of the fabric are also significantly improved, and its service life is extended by 20%.

The experimental data further verifies the significant advantages of this solution in improving fabric quality and performance.

[0111] Technical effect comparison experiment:

[0112] In order to verify the effect of the solution of the present invention in solving the problems of network pattern, spot splitting, wrinkle print and crack print, the following comparative experiments were carried out:

[0113] Four groups of fabrics were selected: Examples 1-3 were fabrics prepared using the above-mentioned solution of the present invention, and the control group was fabrics prepared using a conventional process.

[0114] The comparative experiment includes the following indicators:

[0115] Network pattern: Observe the surface of the fabric through a microscope and record whether there is a network pattern on the fabric.

[0116] Split: The occurrence of warp and weft splitting of fabrics is assessed by visual inspection and tensile testing.

[0117] Wrinkles and cracks: Observe the surface of the fabric under a high-power microscope to see if there are wrinkles and cracks.

[0118] Light transmittance: Use a light transmittance meter to test the light transmittance of the fabric under a standard light source.

[0119] Durability: Evaluate the tensile strength and abrasion resistance of fabrics through tensile testing.

[0120] Experimental data table

[0121]

[0122] Experimental conclusion:

[0123] (1) Significant effect in solving the problem of network texture: Experimental data show that the network texture defect rate of the experimental group is 0%, while that of the control group is as high as 85%. This result shows that the invention completely eliminates the appearance of network texture by rationally designing the twist direction and thickness of the warp and weft yarns, making the surface of the fabric more uniform and smooth.

[0124] (2) The problem of point splitting is significantly reduced: the highest point splitting rate in the experimental group is only 3%, which is much lower than 30% in the control group. This proves that the smelting process (including special auxiliary agent formula and process parameters) in the present invention can effectively untie the network points of the yarn and avoid the point splitting problem.

[0125] (3) Elimination of wrinkle and crack marks: The experimental results show that the wrinkle and crack defect rates of the experimental group are both 0%, while the wrinkle and crack defect rates of the control group are 25% and 20%, respectively. This shows that the present invention effectively avoids common surface defects in the dyeing process by optimizing the dyeing and setting process, especially controlling the dyeing temperature and cycle time.

[0126] (4) Significant improvement in light transmittance: The light transmittance of the experimental group was 72%, significantly better than 60% of the control group. This shows that the present invention improves the structure of the fabric through double-sided slurry treatment and enhances light transmittance, making it more effective in different environments.

[0127] (5) The durability of the fabric is significantly improved: the minimum tensile strength of the experimental group is 1200N / 5cm, and the abrasion resistance is 50,000 times, which is significantly improved compared with the control group (950N / 5cm tensile strength and 40,000 times abrasion resistance). At the same time, the service life of the experimental group is expected to reach 10 years, while the service life of the control group is 8 years, which further verifies the advantages of the present invention in fabric performance and service life.

[0128] Conclusion: Through comparative experiments, it can be concluded that the preparation method provided by the present invention can significantly improve the appearance quality and performance of the transparent roller blind fabric, especially showing great technical advantages in solving defects such as network patterns, point splitting, wrinkle prints and crack prints. At the same time, the light transmittance, tensile strength and durability of the present invention are significantly improved, proving that it has a wide range of application prospects in the roller blind fabric industry.
