Description

Technical Field

[0001] The present application relates to the field of textile fabrics, and more specifically, to a home textile fabric with an imitation embroidery three-dimensional pattern and a preparation method thereof. Background Art

[0002] Jacquard fabric refers to the process of weaving by changing the density, tightness and pattern sequence of the fabric yarn to make the yarn in certain parts rise or fall, thus forming raised patterns, patterns or words on the fabric. Jacquard fabric has the characteristics of clear texture, strong three-dimensional sense, rich colors and soft touch, and is widely used in clothing, curtains, home accessories and other fields.

[0003] In the preparation process of jacquard fabric, it is generally necessary to set the pattern on the grey cloth, which can generally be divided into mechanical jacquard, electronic jacquard and embossed weaving. Mechanical jacquard can weave three-dimensional patterns on grey cloth, but mechanical jacquard is difficult to operate for the design of some complex patterns. Electronic jacquard is a process of jacquard weaving by controlling the jacquard machine through a computer. Although it has greatly improved the production efficiency and precision compared with mechanical jacquard, the mechanical structure is more complex, the operation is difficult and the maintenance cost is high. Embossed weaving refers to molding the flower-shaped pattern on the surface of the fabric, and then coating, printing and other treatments to achieve the flower-shaped effect. However, it is not easy to weave three-dimensional patterns by embossed weaving, which affects the appearance of the finished textile products.

[0004] Therefore, developing a home textile fabric with imitation embroidery three-dimensional pattern that is beautiful and easy to process has become an urgent need in the industry. Summary of the invention

[0005] In order to obtain an embroidery-like three-dimensional pattern home textile fabric that is beautiful and easy to process, the present application provides an embroidery-like three-dimensional pattern home textile fabric and a preparation method thereof.

[0006] In the first aspect, the present application provides an imitation embroidery three-dimensional pattern home textile fabric, adopting the following technical solution: an imitation embroidery three-dimensional pattern home textile fabric, composed of a base fabric and a three-dimensional pattern layer, the three-dimensional pattern layer is made by bonding a three-dimensional pattern adhesive to the surface of the base fabric through screen printing; the three-dimensional pattern adhesive contains the following raw materials in parts by weight: 75-85 parts of thermoplastic polymer, 10-20 parts of thickener, 2-8 parts of pigment, and 120-180 parts of solvent.

[0007] By adopting the above technical scheme, the three-dimensional pattern adhesive is applied to the surface of the base fabric by screen printing, and the three-dimensional pattern adhesive forms a three-dimensional pattern layer on the surface of the base fabric. During the screen printing process, a specific mold is selected for printing according to the desired pattern, so that the finished three-dimensional fabric does not need to be embroidered and woven, and the effect of a three-dimensional textile fabric can be formed, so that the finished product has the advantages of being beautiful and convenient in process.

[0008] Preferably, the base fabric is woven from any one of cotton fiber, silk fiber, and cotton and linen fiber.

[0009] By adopting the above technical scheme, fabrics made of cotton fiber, silk fiber, and cotton and linen fiber have good moisture absorption and air permeability. By utilizing their pore structure and porosity, they are convenient for absorbing and bonding three-dimensional pattern adhesives, so that the three-dimensional pattern layer is more stably attached to the surface of the base fabric, approaching the three-dimensional effect formed by three-dimensional embroidery, so that the finished imitation embroidery three-dimensional home textile fabric has the advantages of both beautiful appearance and convenient process.

[0010] Preferably, the thermoplastic polymer is one or more of PET, nylon 6, and nylon 66.

[0011] By adopting the above technical scheme, the thermoplastic polymer can dissolve and flow after being mixed with the corresponding solvent, which makes it easy to print the three-dimensional pattern adhesive onto the surface of the base fabric during the screen printing process. Combined with the good flexibility and friction resistance of the thermoplastic polymer, the three-dimensional pattern layer is not easily damaged during multiple washing and friction of the finished fabric, and it is not easy for the three-dimensional pattern layer to separate from the surface of the base fabric, thereby ensuring the adhesion stability, water washing resistance and friction resistance of the three-dimensional pattern layer on the surface of the base fabric.

[0012] Preferably, the thickener is an ethyl cellulose solution with a concentration of 1-2%.

[0013] By adopting the above technical scheme, ethyl cellulose has a good miscibility effect in chloroform, a solvent of PET and nylon 6, and can improve the viscosity of the three-dimensional pattern adhesive, thereby ensuring that the three-dimensional pattern adhesive can stably adhere to the surface of the base fabric during the screen printing process; and ethyl cellulose has good water resistance, which can further improve the water washing resistance of the three-dimensional pattern layer, so that after the finished fabric is washed many times, the three-dimensional pattern layer is still adhered to the surface, and the three-dimensional pattern is not easily destroyed and lost due to washing and friction, and it is not easy for the three-dimensional pattern layer to peel off the surface of the base fabric.

[0014] Preferably, the pigment is composed of a washable and sun-resistant environmentally friendly pigment, an antibacterial agent and a flame retardant in a mass ratio of 1:0.05-0.1:0.1-0.2.

[0015] By adopting the above technical scheme, the addition of washable, sun-resistant and environmentally friendly pigments can further improve the washability of the three-dimensional pattern adhesive, ensure the adhesion strength of the three-dimensional pattern on the fabric surface, and utilize the antibacterial effect of the antibacterial agent and the flame retardant effect of the flame retardant to improve the antibacterial and flame retardancy of the finished fabric.

[0016] In a second aspect, the present application provides a method for preparing a home textile fabric with an imitation embroidery three-dimensional pattern, using the following technical solution: A method for preparing a home textile fabric with an imitation embroidery three-dimensional pattern comprises the following steps: S1, the fiber is spun into cloth to obtain grey cloth; then pre-treated to obtain base fabric; S2, mixing and stirring the thermoplastic polymer, thickener, pigment and solvent to obtain a three-dimensional pattern adhesive; S3. Printing the three-dimensional pattern adhesive onto the surface of the base fabric by screen printing, and then subjecting the three-dimensional pattern adhesive to heat treatment, cooling, and post-treatment to form a three-dimensional pattern layer to obtain a finished product.

[0017] By adopting the above technical scheme, after the cotton fiber is used to prepare the basic fabric, the three-dimensional pattern adhesive is bonded to the surface, and then the solvent in the three-dimensional pattern adhesive is removed through heat treatment and post-treatment, so that the three-dimensional pattern layer is stably attached to the surface of the basic fabric to obtain a three-dimensional home textile fabric.

[0018] Preferably, the pretreatment comprises the following steps: After cleaning, drying and leveling, high acyl gellan gum solution is evenly sprayed on the surface of the grey cloth where the pattern needs to be printed, and the high acyl gellan gum solution is 80-120 mL per square meter of spraying area on the grey cloth surface; then hydroxyapatite ultra-long nanowires are evenly added, and the addition amount of hydroxyapatite ultra-long nanowires per square meter of spraying area on the grey cloth surface is 30-120 g; finally, tributyl citrate and ethyl cellulose composite liquid is evenly sprayed, and the tributyl citrate and ethyl cellulose composite liquid is 80-120 mL per square meter of spraying area on the grey cloth surface, and finally dried.

[0019] Preferably, the tributyl citrate and ethyl cellulose composite liquid is prepared from tributyl citrate, ethyl cellulose, chloroform and ethanol in a mass ratio of 1-3:1-3:44-48:50.

[0020] By adopting the above technical scheme, the surface of the base fabric contains pores and hydrophilic groups, which are convenient for attracting and connecting with the hydroxyl groups in the high acyl gellan gum solution. Then, the viscosity of the high acyl gellan gum solution is utilized to bond the ultra-long hydroxyapatite nanowires to the surface of the high acyl gellan gum solution. The flexibility of the ultra-long hydroxyapatite nanowires is combined with the flexibility of the high acyl gellan gum to make the base fabric have better flexibility. During the twisting and wringing process, the three-dimensional pattern layer is not easily deformed, thereby ensuring that the three-dimensional pattern layer is not easily peeled off from the surface of the base fabric, and improving the friction resistance and water washing resistance of the three-dimensional pattern home textile fabric.

[0021] High acyl gellan gum, hydroxyapatite nanowires, tributyl citrate and ethyl cellulose are coordinated, and the carboxyl groups on the surface of tributyl citrate are attracted and connected to the hydroxyl groups in the high acyl gellan gum and the hydroxyl groups on the surface of the hydroxyapatite nanowires, so that the tributyl citrate hydrophobic agent faces outward, and the viscosity of the ethyl cellulose solution is combined to facilitate the blocking of the tributyl citrate on the surface of the base fabric; the solvent in the three-dimensional pattern adhesive can dissolve the ethyl cellulose, exposing the ester group of the tributyl citrate to contact with the thermoplastic polymer, achieving a connection effect, improving the bonding stability between the base fabric and the three-dimensional pattern adhesive, and combining with the plasticizing effect of tributyl citrate to further improve the friction resistance and water washing resistance of the finished fabric. Even after repeated water washing, the three-dimensional pattern layer on the surface is not easy to separate from the surface of the base fabric, thereby ensuring the water washing fastness of the three-dimensional pattern layer on the fabric.

[0022] Preferably, the heat treatment temperature is 140-155° C., and the heat treatment time is 3-10 min.

[0023] By adopting the above technical scheme, the temperature and time of the heat treatment are limited to ensure that the solvent can be removed during the heat treatment process, so that the three-dimensional pattern adhesive can stably adhere to the surface of the base fabric, and promote the cross-linking and curing of the thermoplastic elastomer, thereby improving the stability of the three-dimensional pattern layer on the surface of the base fabric. Even after multiple washings and frictions, the three-dimensional pattern adhesive layer on the surface of the base fabric is not easily peeled off.

[0024] Preferably, the specific steps of the post-treatment are as follows: washing with water for 2-3 times, and then heating and drying for 10-20 minutes.

[0025] By adopting the above technical solution, water washing and drying treatment can further ensure the removal of solvents and improve the cleanliness and comfort of the fabric.

[0026] In summary, this application has the following beneficial effects: 1. The three-dimensional pattern adhesive is applied to the surface of the base fabric by screen printing. The three-dimensional pattern adhesive forms a three-dimensional pattern layer on the surface of the base fabric. During the screen printing process, a specific mold is selected for printing according to the desired pattern, so that the finished three-dimensional fabric does not need to be embroidered and woven, and the effect of a three-dimensional textile fabric can be formed, so that the finished product has the advantages of being beautiful and convenient in process.

[0027] 2. Thermoplastic polymers dissolve and flow under the action of solvents, ensuring the printing effect of the three-dimensional pattern adhesive during the screen printing process. Combined with the thickening effect of the thickener, the three-dimensional pattern adhesive is ensured to be relatively stably bonded to the surface of the base fabric after printing, thereby ensuring that the three-dimensional pattern layer is stably attached to the surface of the base fabric, achieving the effect of the base fabric surface stably loading the three-dimensional pattern layer, approaching the stability of three-dimensional embroidery, but compared with three-dimensional embroidery, it saves manpower and time, and the finished product has the advantage of convenient process.

[0028] 3. Cotton fiber, silk fiber, cotton and linen fiber have poor compatibility with thermoplastic polymers. Directly applying three-dimensional pattern adhesive on the surface of the base fabric can easily affect the adhesion effect of the three-dimensional pattern layer on the surface of the base fabric. High acyl gellan gum solution and hydroxyapatite nanowires are used as the connection basis, combined with the plasticizing connection effect of tributyl citrate in the composite solution of tributyl citrate and ethyl cellulose, and the bonding effect of ethyl cellulose, to improve the bonding effect between the base fabric and the three-dimensional pattern adhesive, ensure the flexibility and friction resistance of the fabric, and make the fabric have good water washing resistance, so that the three-dimensional pattern layer is not easy to separate from the base fabric after the fabric is washed many times.

[0029] 4. Thermoplastic polymers, high acyl gellan gum, ultra-long hydroxyapatite nanowires, and tributyl citrate cooperate with each other, utilizing the good flexibility of thermoplasticity, the good flexibility of high acyl gellan gum, the good flexibility of ultra-long hydroxyapatite nanowires, and the plasticizing effect of tributyl citrate on thermoplastic polymers to improve the flexibility of the finished three-dimensional patterned home textile fabrics, so that the fabrics can be bent and folded, and the three-dimensional pattern layer can be restored after bending, folding, or twisting and wringing, so that after the finished fabrics are washed many times, the three-dimensional pattern layer on the surface of the base fabric is still stable in shape, and the three-dimensional pattern layer is not prone to cracking and blistering.

[0039] Embodiment 4: This embodiment differs from Embodiment 1 in that: No high acyl gellan gum solution and hydroxyapatite ultralong nanowires were added to S1.

[0040] Embodiment 5: This embodiment differs from Embodiment 1 in that: In S1, the hydroxyapatite ultralong nanowires were replaced by silica whiskers of equal mass, and the average length of the silica whiskers was 40 μm.

[0041] Embodiment 6: This embodiment differs from Embodiment 1 in that: No tributyl citrate and ethyl cellulose composite solution was added to S1.

[0042] Embodiment 7: This embodiment differs from Embodiment 1 in that: Tributyl citrate was not added to the tributyl citrate and ethyl cellulose composite solution of S1.

[0043] Performance testing 1. Aesthetics test The methods of Examples 1-3 were respectively used to prepare three-dimensional patterned home textile fabrics, and the aesthetics of the three-dimensional pattern layer on the surface was scored, with 10 points for beautiful and three-dimensional → 1 point for poor three-dimensionality and low aesthetics.

[0044] 2. Friction resistance test The methods of Examples 1-7 were respectively used to prepare three-dimensional patterned home textile fabrics, and the finished fabrics were scrubbed and rubbed. After scrubbing and rubbing for 240 hours, the three-dimensional pattern layer on the surface of the three-dimensional patterned home textile fabric was observed to see whether there were cracks, peeling, and blistering problems. The total area of ​​cracks, peeling, and blistering per unit area was recorded. The larger the total area, the worse the friction resistance.

[0045] 3. Washability test The methods of Examples 1-7 were respectively used to prepare three-dimensional patterned home textile fabrics. The fabrics were washed in a washing machine for 45 minutes each time and washed 30 times. The bonding strength of the three-dimensional pattern layer on the surface of the base fabric was observed, and the area per unit area where the three-dimensional pattern layer was separated from the base fabric was recorded. The larger the separation area, the worse the wash resistance.

[0046] 4. Flexibility test The methods of Examples 1-7 were respectively used to prepare three-dimensional patterned home textile fabrics. After the fabrics were moistened, they were twisted 360 degrees, allowed to stand for 30 seconds, and then flattened and dried; after wetting again, they were twisted 360 degrees, allowed to stand for 30 seconds, and then flattened and dried; the operation was repeated 30 times, and the bubble area generated by the three-dimensional pattern layer per unit area and the area where the three-dimensional pattern layer was separated from the surface of the base fabric were recorded, and the total area was calculated. The larger the total area, the worse the flexibility.

[0047] Table 1 Performance Test Table (“ / ” in the following table means that the corresponding embodiment or comparative example did not test the item, so there is no data) From Examples 1-3 and Table 1, it can be seen that the fabric prepared in the present application has good aesthetics, and the cracks, peeling and blistering areas after friction are small, indicating good friction resistance. After washing, the area of ​​the three-dimensional pattern layer separated from the base fabric is small, indicating good water resistance. After repeated twisting, the area of ​​the three-dimensional pattern layer separated from the base fabric is small, indicating good flexibility. During repeated rubbing, friction, water soaking and wringing, the three-dimensional pattern layer on the surface of the three-dimensional pattern home textile fabric still has good bonding stability on the surface of the base fabric.

[0048] It can be seen from Example 1 and Examples 4-7 and Table 1 that no high acyl gellan gum solution and hydroxyapatite ultra-long nanowires are added to S1 of Example 4. Compared with Example 1, the friction resistance of the fabric prepared in Example 4 is worse than that in Example 1, the water resistance is worse than that in Example 1, and the flexibility is worse than that in Example 1; this indicates that high acyl gellan gum and hydroxyapatite ultra-long nanowires have good wear resistance, which can improve the wear resistance of the fabric, and both have good flexibility, which can improve the flexibility of the fabric; at the same time, the water resistance effect can be enhanced.

[0049] In S1 of Example 5, the hydroxyapatite ultra-long nanowires are replaced with silica whiskers of equal mass, and the average length of the silica whiskers is 40 μm. Compared with Example 1, the fabric prepared in Example 5 has worse friction resistance, water resistance, and flexibility than Example 1, which indicates that the short silica whisker filaments have poor toughness, while the hydroxyapatite ultra-long nanowires have good toughness, which can improve the flexibility of the finished fabric, promote stable bonding between the base fabric and the three-dimensional pattern layer, and improve the friction resistance and water resistance of the fabric.

[0050] No tributyl citrate and ethyl cellulose composite liquid is added to S1 of Example 6. Compared with Example 1, the fabric prepared in Example 6 has worse friction resistance, water resistance and flexibility than Example 1. This indicates that tributyl citrate and ethyl cellulose can cooperate to plasticize and cross-link the base fabric and the three-dimensional pattern adhesive, thereby improving the flexibility and bonding stability of the fabric, making the fabric wear-resistant and water-washing-resistant, and making it less likely for the three-dimensional pattern layer to separate from the surface of the base fabric.

[0051] No tributyl citrate was added to the tributyl citrate and ethyl cellulose composite liquid of S1 in Example 7. Compared with Example 1, the fabric prepared in Example 7 had worse friction resistance, water resistance and flexibility than Example 1. This indicates that the addition of tributyl citrate can improve the bonding effect between the three-dimensional pattern layer and the base fabric, improve the friction resistance, and improve the flexibility of the finished fabric due to the better plasticizing effect of tributyl citrate. The hydrophilic group of tributyl citrate faces the base fabric layer, while the hydrophobic agent faces outward, thereby improving the water resistance of the finished fabric.

[0052] 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 modifications to the present embodiment without any creative contribution as needed. However, as long as it is within the scope of the claims of the present application, it shall be protected by the patent law.
