Jacquard fabric and processing technology thereof

Abstract

The present application relates to the technical field of textile fabrics, and in particular to a jacquard fabric and its processing technology. The processing technology of a jacquard fabric includes: padding → drying → hot calendering → baking. In the padding step, the jacquard fabric is immersed in an impregnation liquid.

The formed film layer has good high-temperature resistance, allowing the jacquard fabric to be hot-calendered at a higher temperature, increasing the orientation of the fibers and the brightness of the film layer, thereby improving the brightness of the jacquard fabric and its water-washing resistance.

Description

Technical Field

[0001] The present application relates to the technical field of textile fabrics, and in particular to a jacquard fabric and a processing technology thereof. Background Art

[0002] Jacquard fabrics are divided into single-color jacquard and multi-color jacquard fabrics. Multi-color jacquard fabrics have good decorative effects, with distinct patterns and strong three-dimensional convexity. However, they are not very comfortable to the human touch. In order to improve the tactile comfort of jacquard fabrics, plant fibers are often used to prepare jacquard fabrics.

[0003] Plant fiber yarns are prone to lint and wrinkles, resulting in poor gloss and decorative effects for the resulting jacquard fabrics. Currently, jacquard fabrics made from plant fibers are often calendered to enhance their gloss. However, the gloss and washability of calendered jacquard fabrics are unsatisfactory, with the gloss essentially disappearing after washing. Summary of the Invention

[0004] In order to overcome the problem of unsatisfactory brightness and washability of jacquard fabrics after calendering, the present application provides a jacquard fabric and a processing technology thereof.

[0005] In a first aspect, the present application provides a processing technology for jacquard fabrics, which adopts the following technical solutions:

[0006] Padding → drying → hot calendering → baking;

[0007] In the padding step, the jacquard fabric is placed in the impregnation liquid and immersed;

[0008] The impregnation liquid comprises, by weight, 8-10 parts of a brightening and smoothing agent, 2-4 parts of a softening agent, 15-25 parts of an organosilicon-modified aqueous polyurethane solution, 3-6 parts of glycerin, and 100-120 parts of water;

[0009] The temperature of the hot calendering is 180-200°C.

[0010] By adopting the above technical solution, the jacquard fabric is treated with an impregnation liquid, which forms a film layer on the jacquard fabric. During the film-forming process, the silicone-modified waterborne polyurethane reacts with the active groups on the jacquard fabric, reducing the number of active groups on the jacquard fabric surface and enhancing the smoothness of the jacquard fabric. Furthermore, the waterborne polyurethane in the film layer forms a network structure, preventing the loss of the brightening and smoothing agent, softening agent, and glycerin in the impregnation liquid during washing, thereby enhancing the brightness of the jacquard fabric after washing.

[0011] Silicone-modified waterborne polyurethane improves the high-temperature resistance of the waterborne polyurethane and the sticking phenomenon of the film formed by the waterborne polyurethane at higher hot calendering temperatures, so that the jacquard fabric can be hot calendered at higher temperatures, thereby increasing the orientation of the fibers and the brightness of the polyurethane film.

[0012] Glycerol is impregnated into the fiber. On the one hand, it increases the adhesion of the fluff on the fiber after the calendering process, so that the fluff is tightly pressed on the fiber. On the other hand, glycerol protects the jacquard fabric from damage at higher hot calendering temperatures, thereby enhancing the brightness of the jacquard fabric.

[0013] Preferably, the rolling rate of the impregnation is 70-80%.

[0014] By adopting the above technical solution, the rolling rate is controlled, and the impregnation liquid on the jacquard fabric is controlled, so that the impregnation liquid effectively forms a film on the jacquard fabric, and the effect of hot calendering on improving brightness is better.

[0015] Preferably, the preparation process of the organosilicon-modified aqueous polyurethane solution is as follows:

[0016] Preparation of a polyurethane prepolymer: 100-120 parts by mass of polyethylene glycol, 80-90 parts by mass of hydroxyl-terminated polydimethylsiloxane, and 2-4 parts by mass of glycerol are mixed to form a mixed solution, the mixed solution is heated to 70-90° C., 100-110 parts by mass of diphenylmethane diisocyanate is added under nitrogen protection and stirring at 300-500 rpm, and the mixture is reacted for 0.6-1.2 hours to prepare a polyurethane prepolymer;

[0017] Salt formation and emulsification: add 4-6 parts by mass of dimethylolpropionic acid to the polyurethane prepolymer, and react for 2.5 hours under stirring at 1000 r / min; then reduce the temperature to 40°C, add 8-12 parts by mass of acetone, then add 3-5 parts by mass of triethylamine, react for 1 hour, reduce the temperature, add 1200 parts by mass of water, and emulsify under stirring at 1000-1500 r / min; then add 1-3 parts by mass of ethylenediamine for chain extension, increase the temperature to 70-90°C, and react for 0.5-1 hour under stirring at 500 r / min to prepare a silicone-modified waterborne polyurethane solution.

[0018] By adopting the above technical solution, silicone is introduced into the soft segment of waterborne polyurethane, thereby improving the high temperature resistance of the film layer formed by the waterborne polyurethane.

[0019] Preferably, the impregnation solution further comprises 0.3-0.6 parts by mass of polyvinyl alcohol.

[0020] By adopting the above technical solution, the adhesion performance of water-based polyurethane on jacquard fabric is improved, and the effect of the fluff on the fiber being pressed tightly on the fiber after the calendering process is further improved.

[0021] Preferably, the impregnation solution further comprises 1-2 parts by mass of aqueous nano-montmorillonite.

[0022] By adopting the above technical solution, on the one hand, water-based nano-montmorillonite is added to the impregnation liquid, and the adsorption of the water-based nano-montmorillonite reduces the loss of brightening and smoothing agents, softeners and glycerin in the film layer formed by the impregnation liquid during the washing process, thereby enhancing the brightness of the jacquard fabric after washing; on the other hand, the water-based nano-montmorillonite further enhances the heat resistance of the film layer formed by the silicone-modified water-based polyurethane.

[0023] Preferably, the impregnation liquid further comprises 0.3-1 parts by mass of an acrylic leveling agent.

[0024] By adopting the above technical solution, the acrylic leveling agent is used in combination with the water-based nano-montmorillonite to increase the leveling performance of the film formed by the impregnation liquid, and improve the problems of poor leveling performance and uneven film layer that may occur when adding water-based nano-montmorillonite.

[0025] Preferably, the acrylic leveling agent is polyacrylate leveling agent BYK 358N or polyacrylate BYK-361N.

[0026] By adopting the above technical solution, the preferred acrylic leveling agent can further enhance the brightness of the jacquard fabric and its water-resistant performance.

[0027] Preferably, the impregnation liquid further comprises 0.3-0.5 parts by mass of an organosilicon-based leveling agent.

[0028] By adopting the above technical solution, the smoothness and high temperature resistance of the film layer formed by the impregnation liquid are further improved, thereby improving the brightness of the jacquard fabric.

[0029] Preferably, the organosilicon-based leveling agent is one of BYK-320 leveling agent, BYK-306 leveling agent, and leveling agent LAG-6017.

[0030] By adopting the above technical solution, the smoothness and anti-adhesion properties of the film layer formed by the impregnating liquid are further improved, thereby improving the brightness of the jacquard fabric.

[0031] In the second aspect, a jacquard fabric is prepared using the jacquard fabric processing technology described in this application;

[0032] The textile fiber of the jacquard fabric is one of cotton fiber, flax fiber, ramie fiber, jute fiber, kapok fiber, coconut fiber and bamboo fiber.

[0033] By adopting the above technical solution, the textile fibers of the jacquard fabric are made of plant fibers such as cotton, flax, ramie, jute, and kapok, which improves the tactile comfort of the jacquard fabric. At the same time, the active groups on the plant fibers can enhance the adhesion of the film layer formed by water-based polyurethane on the jacquard fabric, thereby improving the brightness of the jacquard fabric and its washability.

[0034] In summary, this application has the following beneficial effects:

[0035] 1. The processing technology of the jacquard fabric in the present application includes: padding → drying → hot calendering → baking; in the padding step, the jacquard fabric is treated with an impregnation liquid, and the silicone-modified water-based polyurethane in the impregnation liquid forms a film layer on the jacquard fabric, which enhances the flatness of the jacquard fabric and reduces the loss of brightening smoothing agent, softener and glycerin during washing. The formed film layer has good high-temperature resistance, so that the jacquard fabric can be hot-calendered at a higher temperature, thereby increasing the orientation of the fibers and the brightness of the formed film layer, thereby improving the brightness of the jacquard fabric and the water-washing resistance of the brightness.

[0036] 2. This application uses a combination of silicone-modified water-based polyurethane, water-based nano-montmorillonite and a silicone-based leveling agent to improve the high-temperature resistance of the film layer formed by the impregnation liquid; glycerin protects the jacquard fabric from damage at higher hot calendering temperatures; glycerin, silicone-modified water-based polyurethane and a silicone-based leveling agent are used in combination to further improve the brightness of the jacquard fabric and its water-washing resistance.

[0037] 3. This application uses water-based nano-montmorillonite and acrylic leveling agent in combination to further improve the brightness and washability of jacquard fabrics. DETAILED DESCRIPTION

[0063] Example

[0064] Example 1, a processing technology for jacquard fabric, adopts the following preparation process:

[0065] Padding → drying → hot calendering → baking;

[0066] Padding step: The jacquard fabric prepared from cotton fiber (specifications: 21s*21s / 52*58) was passed through an immersion tank (the length of the immersion tank was 3 meters) at a speed of 3 m / min, and the temperature of the immersion tank was maintained at 65°C, so that the jacquard fabric fully absorbed the impregnation liquid (prepared in Preparation Example 5) in the immersion tank. After the jacquard fabric emerged from the immersion tank, it was squeezed at room temperature and a pressure of 4 MPa. Then, a second dipping step was performed: the jacquard fabric was passed through an immersion tank (the length of the immersion tank was 3 meters) at a speed of 3 m / min, and the temperature of the immersion tank was maintained at 65°C, so that the jacquard fabric fully absorbed the impregnation liquid (prepared in Preparation Example 5) in the immersion tank. After the jacquard fabric emerged from the immersion tank, it was squeezed at a pressure of 4 MPa, and the squeeze rate was controlled at 70%.

[0067] Drying, hot calendering and baking steps: After the jacquard fabric is dried at a temperature of 100°C for 5 minutes, it enters the calender at a travel speed of 30m / min for calendering (the calender temperature is 180°C and the pressure is 7MPa). Finally, the fabric is placed at a temperature of 160°C and baked for 2 minutes to prepare a jacquard fabric with high brightness.

[0068] Example 2, a processing technology for a jacquard fabric, differs from Example 1 in that the jacquard fabric (specifications: 21s*21s / 52*58) is prepared using bamboo fiber; the impregnation liquid uses the impregnation liquid of Preparation Example 6; the calender temperature is 190°C; and the rolling rate is controlled at 75%.

[0069] Example 3, a processing technology for a jacquard fabric, differs from Example 1 in that the jacquard fabric (specification: 21s*21s / 52*58) is prepared using ramie fiber; the impregnation liquid uses the impregnation liquid of Preparation Example 7; the calender temperature is 200°C; and the rolling rate is controlled at 80%.

[0070] Examples 4-11 are a process for processing jacquard fabrics. The difference from Example 1 is that the impregnation liquids used are the impregnation liquids of Preparation Examples 8-15 in sequence.

[0071] Comparative Example

[0072] Comparative Example 1 is a processing technology for a jacquard fabric, which differs from Example 11 in that no silicone-modified aqueous polyurethane solution is used in the impregnation liquid.

[0073] Comparative Example 2 is a processing technology for jacquard fabrics. The difference from Example 11 is that hydroxyl-terminated polydimethylsiloxane is not used in the raw materials for preparing the silicone-modified aqueous polyurethane solution; and glycerin is not used in the impregnation solution.

[0074] Comparative Example 3 is a processing technology for a jacquard fabric, which differs from Example 11 in that no silicone-modified aqueous polyurethane solution is used; and the temperature of the hot calendering is 170°C.

[0075] Comparative Example 4 is a processing technology for a jacquard fabric, which differs from Example 11 in that the silicone-modified aqueous polyurethane solution and glycerin are not used; and the hot calendering temperature is 210°C.

[0076] Performance testing

[0077] Test 1: Brightness

[0078] The brightness of the samples was tested using a WG68 brightness meter according to the national standard FZT01097-2006 "Test method for fabric gloss" on the jacquard fabric before washing and after 10 standard washes.

[0079] Test 2: Strong:

[0080] In accordance with GB / T 3923.1-2013 "Tensile properties of textile fabrics - Part 1: Determination of breaking strength and elongation at break (Strip method)".

[0081] Test samples: The jacquard fabrics prepared in Examples 1-9 were test samples; the jacquard fabrics prepared in Comparative Examples 1-4 were comparative samples; and a cotton jacquard fabric (specifications: 21s*21s / 52*58) that had not been processed by the jacquard fabric processing technology of the present application was used as a control sample.

[0082] Test results: The test results of brightness and strength of the jacquard fabrics prepared in Examples 1-11, Comparative Examples 1-4 and the control sample are shown in Table 3.

[0083] Table 3 Test results of brightness and strength of jacquard fabrics prepared in Examples 1-11, Comparative Examples 1-4 and control samples

[0084]

[0085] Combining Examples 1-11 and Comparative Examples 1-4 and Table 3, it can be seen that

[0086] The brightness and strength of the jacquard fabrics prepared in Examples 1-11 are better than those of the jacquard fabrics prepared in Comparative Examples 1-4, indicating that the combination of silicone-modified aqueous polyurethane solution, glycerin, brightening and smoothing agent, softener, polyvinyl alcohol, aqueous nano-montmorillonite, acrylic leveling agent and silicone leveling agent improves the brightness, washability and strength of the jacquard fabric.

[0087] The reason is that the film layer formed by the silicone-modified water-based polyurethane in the impregnating liquid on the jacquard fabric improves the flatness of the jacquard fabric and reduces the loss of brightening and smoothing agents and softeners during washing; it improves the high-temperature resistance of the film layer formed by the impregnating liquid, increases the orientation of the fiber after hot calendering and the adhesion of the fluff on the fiber to the fiber, and improves the density of the yarn of the jacquard fabric, thereby improving the brightness, washability and strength of the prepared jacquard fabric.

[0088] The jacquard fabric prepared in comparative document 3 has poor brightness and strength, which may be because silicone-modified water-based polyurethane solution is not used, and the brightening and smoothing agent and softener are lost more during the washing process, and the flatness of the jacquard fabric is reduced; the hot calendering temperature of 170°C is low, and the fiber orientation is insufficient, which makes the brightness, water washing resistance and strength of the prepared jacquard fabric reduced.

[0089] The brightness and strength of the jacquard fabric prepared in comparative document 4 are poor, which may be because the brightening and smoothing agent and softener are lost more during the washing process and the flatness of the jacquard fabric is reduced; without the use of glycerin, the fibers of the jacquard fabric are easily damaged at the hot calendering temperature of 210°C, resulting in a decrease in the brightness, washability and strength of the prepared jacquard fabric.

[0090] The brightness and strength of the jacquard fabrics prepared in Examples 1-3 are better than those of the jacquard fabric prepared in Example 4. This may be because polyvinyl alcohol and aqueous nano-montmorillonite are used in combination in Examples 1-3. Polyvinyl alcohol increases the amount of impregnation liquid attached to the jacquard fabric fibers, the stability and dispersibility of nano-montmorillonite, and the density of the yarns of the jacquard fabric, thereby improving the strength of the jacquard fabric; the nano-montmorillonite has an adsorption effect on the brightening and smoothing agent and the softening agent, reducing the migration of the brightening and smoothing agent and the softening agent during the washing process. The combination of polyvinyl alcohol and nano-montmorillonite improves the brightness, washability, and strength of the prepared jacquard fabric.

[0091] The brightness and strength of the jacquard fabrics prepared in Examples 1-3 are better than those of the jacquard fabric prepared in Example 5. This may be because the polyvinyl alcohol and acrylic leveling agent are used in combination in Examples 1-3, which makes the impregnation liquid have better dispersibility and fluidity, improves the uniformity of the film layer prepared by the impregnation liquid and its adhesion to the jacquard fabric, and thus improves the brightness, water washability and strength of the prepared jacquard fabric.

[0092] The brightness and strength of the jacquard fabrics prepared in Examples 1-3 are better than those prepared in Example 6. This may be because in Examples 1-3, water-based nano-montmorillonite and acrylic leveling agent are used in combination. The water-based nano-montmorillonite improves the high-temperature resistance of the film layer formed by the impregnation liquid and the water-washing resistance of the brightening and smoothing agent and softener in the film layer. In addition, the acrylic leveling agent has good wrapping properties for the water-based nano-montmorillonite, making the formed film layer smoother after hot calendering, thereby improving the brightness and water-washing resistance of the prepared jacquard fabric.

[0093] The water-based nano-montmorillonite improves the high-temperature resistance of the film layer formed by the impregnation solution, and is combined with the high temperature of hot calendering and the protection of glycerol on the fiber to improve the orientation of the fibers of the jacquard fabric, thereby improving the strength of the prepared jacquard fabric.

[0094] The brightness and strength of the jacquard fabrics prepared in Examples 1-3 are better than those prepared in Example 7. This may be because 600-mesh ordinary montmorillonite is used in Example 7. The ordinary montmorillonite has a large particle size and poor dispersibility, which reduces the flatness of the film layer formed by the impregnation liquid after hot calendering. The impregnation liquid has insufficient reinforcement performance on the fibers of the jacquard fabric, thereby reducing the brightness, washability and strength of the prepared jacquard fabric.

[0095] The brightness and strength of the jacquard fabrics prepared in Examples 1-3 are better than those prepared in Examples 8-9. This may be because the combination of the silicone leveling agent and the acrylic leveling agent in Examples 1-3 improves the smoothness of the film layer formed by the impregnating liquid, and the silicone leveling agent improves the high temperature resistance of the film layer, allowing the film layer to be hot-calendered at a higher temperature, thereby improving the orientation of the fibers; the acrylic leveling agent improves the density of the film layer, thereby improving the brightness, washability, and strength of the prepared jacquard fabric.

[0096] The brightness and strength of the jacquard fabrics prepared in Examples 1-3 are better than those of the jacquard fabric prepared in Example 10. This may be because in Example 10, the hydroxyl-terminated dimethyl silicone oil in the silicone-modified waterborne polyurethane solution of Preparation Example 4 was added after the isocyanate and diol reacted for a period of time. The silicone in the synthesized waterborne polyurethane was relatively concentrated, and the modification effect on the soft segment of the waterborne polyurethane was poor, resulting in poor high-temperature resistance of the silicone-modified waterborne polyurethane. The film layer prepared by the impregnation solution may stick to the roller, and the smoothness of the film layer is reduced, which in turn reduces the brightness of the prepared jacquard fabric.

[0097] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but as long as they are within the scope of the claims of the present application, they are protected by the patent law.
