Description

Technical Field

[0001] The invention belongs to the technical field of fabric finishing, and in particular relates to a velvet-proof fabric finishing glue and a preparation method and application thereof. Background Art

[0002] Fabric post-treatment refers to a series of processing steps after the fabric or fabric is produced to improve its appearance, feel, performance or give it special functions. Common fabric post-treatment methods include dyeing and printing, waterproof treatment, anti-fouling treatment, flame retardant treatment, raising treatment, anti-static treatment, etc. For certain types of fabrics, such as down jackets and wool products, anti-down treatment is also very necessary.

[0003] Conventional anti-down treatments include calendering and coating. The specific process of calendering is that the fabric passes through one or more pairs of rollers at a fast speed under a certain pressure, using high temperature and / or high pressure to make the fiber surface smooth, and can make the fibers on the surface of the fabric more compact and reduce gaps, thereby preventing the down from leaking out. Calendering has the following disadvantages:

[0004] (1) High temperature calendering may cause the fiber surface to melt or deform, especially for some temperature-sensitive synthetic fibers, which will lead to a decrease in fiber strength and affect the durability of the fabric.

[0005] (2) After calendering, the fabric will become stiffer and lose its original softness and elasticity.

[0006] (3) Even after calendering, the anti-down effect is difficult to reach less than 10 strands. Some fine down may still penetrate the fabric, and it is impossible to completely prevent the down from leaking out. Especially after long-term use or washing, the anti-down effect may be further weakened.

[0007] (4) High temperature treatment may cause dye sublimation or color fading, affecting the color quality of the fabric.

[0008] The specific process of coating treatment is to apply one or more layers of anti-down glue (usually chemical materials such as polyurethane and acrylic acid) on one or both sides of the fabric. These coatings can form a continuous film layer on the surface of the fabric, effectively closing the gaps between the fibers and preventing the down from escaping from the fabric. Or use a pre-prepared film and directly bond it to the fabric. Coating treatment has the following disadvantages:

[0009] (1) The film layer formed by the coating or film will hinder air circulation, reducing the breathability of the fabric, and you may feel stuffy and uncomfortable when wearing it.

[0010] (2) Coating or filming will increase the weight of the fabric, making the finished garment appear bulky and reducing the light feeling.

[0011] (3) Coated fabrics usually become stiffer and lose their original softness and natural drape.

[0012] (4) After repeated washing or long-term use, the coating may crack, peel off, etc., resulting in a decrease in the anti-velvet effect.

[0013] Therefore, there is an urgent need for a multifunctional process in which a fabric can still remain soft, down-proof, windproof, breathable, etc. after being subjected to down-proof finishing. Summary of the invention

[0014] The purpose of the present invention is to provide a finishing glue for anti-down fabrics and its preparation method and application, so as to solve the problem that the anti-down effect is poor in the process of finishing the fabrics with anti-down by calendering and coating, and the air permeability and softness of the fabrics themselves will be affected. The present invention uses an oily polyurethane glue solution and water to form an incompatible oil-in-water suspension, and after micro-concave high-precision coating, rolling is performed to increase the glue filling of the fabric fiber gaps, and then a microporous membrane is formed in the fabric fiber gaps during the drying process. This filling formation makes the fabric have the advantages of soft hand feel, high air permeability, and high anti-down.

[0015] In order to achieve the above object, the present invention provides the following technical solutions:

[0016] The first aspect of the present invention provides a finishing glue for anti-velvet fabrics, the finishing glue comprising an oily polyurethane glue solution and water, wherein the oily polyurethane glue solution comprises, by weight, 1 to 5 parts of oily polyurethane particles, 0.005 to 0.2 parts of a low-temperature cross-linking agent, 0.005 to 0.2 parts of a first organic solvent and 1 to 5 parts of a second organic solvent, the boiling point of the first organic solvent being higher than that of water, and the boiling point of the second organic solvent being lower than that of water.

[0017] Preferably, the mass ratio of the oily polyurethane adhesive solution to water is (0.5-1.5):(0.5-1.5).

[0018] Preferably, the first organic solvent is N,N-dimethylformamide.

[0019] The N,N-dimethylformamide (DMF) used in the present invention is an organic solvent compatible with oil and water, and is a high boiling point solvent. The present invention utilizes a small amount of the solvent to promote the fusion of amphoteric liquids to form a stable suspended liquid in the initial stage of oil-water mixing, and can form micro-nano water liquid particles inside the liquid. After the second organic solvent is completely evaporated, the overall glue has formed a complete micro-nano sponge-type water droplet structure, and at the same time has a certain property of not being completely solidified, which is conducive to the discharge of water vapor during subsequent temperature rise to form a transparent micro-nano pore structure membrane, and has a high anti-velvet and high breathability effect.

[0020] Preferably, the second organic solvent is one or more of benzene, ethylene dichloride, and butanone.

[0021] The second organic solvent in the present invention has a boiling point lower than 100 degrees Celsius and is an oily organic solvent. Its function is to completely evaporate the second organic solvent before water boils, so that the oily polyurethane is initially solidified to obtain a microporous structure.

[0022] More preferably, the second organic solvent is butanone.

[0023] The prepared post-finishing glue of the present invention is water droplets formed by the oily glue (oily polyurethane glue solution) and water under the conditions of high-speed stirring and ultrasonic homogenization, which form nano-scale liquid water clusters in the post-finishing glue, are evenly coated on the surface of the fabric and go through a drying process. The solvents butanone and water in the oily glue have different volatilization points. First, butanone volatilizes to form a glue film for preliminary solidification, and then the nano-scale liquid water clusters are evenly distributed in the solidified glue film. After solidification, nano bubbles in the glue film are heated up again and volatilized to form a micro-nano porous film. The micro-nano porous film fills the gap structure inside the fabric fiber, thereby achieving a good anti-down and breathable effect.

[0024] The second aspect of the present invention provides a method for preparing a velvet-proof fabric finishing glue, comprising the following steps:

[0025] (1) adding a second organic solvent to the oily polyurethane particles under stirring and ultrasound to completely dissolve the oily polyurethane particles, and then adding a low-temperature crosslinking agent and the first organic solvent and continuously stirring to obtain an oily polyurethane glue solution;

[0026] (2) The oily polyurethane glue solution and water are mixed according to a mass ratio to obtain a mixture, and then the mixture is emulsified into a uniform suspension under stirring and ultrasonic conditions, namely, the finishing glue.

[0027] Preferably, in step (1), the stirring speed is 0 to 1500 r / min, the ultrasonic frequency is 15 to 60 kHz, the ultrasonic power is 500 to 3000 W, and the stirring and ultrasonic time is 1 to 24 h.

[0028] More preferably, in step (1), the stirring speed is 500 r / min, the ultrasonic frequency is 20 kHz, the ultrasonic power is 1500 W, and the stirring and ultrasonic time is 8 h.

[0029] Preferably, in step (2), the stirring speed is 0 to 1500 r / min, the ultrasonic frequency is 15 to 60 kHz, the ultrasonic power is 500 to 3000 W, and the stirring and ultrasonic time is 1 to 24 h.

[0030] More preferably, in step (2), the stirring speed is 800 r / min, the ultrasonic frequency is 40 kHz, the ultrasonic power is 2000 W, and the stirring and ultrasonic time is 6 h.

[0031] A third aspect of the present invention provides an application of a post-finishing glue for a down-proof fabric, and an application of the post-finishing glue in a down-proof treatment of the fabric.

[0032] Preferably, the specific process of carrying out the anti-down treatment on the fabric is:

[0033] The finishing glue is coated and rolled into the gaps on the surface of the fabric by a compound machine with rolling and drying functions; the compound machine includes an anilox roller, and the mesh cells on the anilox roller for applying glue are in the shape of a quadrangular pyramid or a hexagonal pyramid.

[0034] The present invention forms a uniform glue coating on one side of the fabric by a high-precision concave glue coating method, and forms a process of pressing and drying the fiber gaps inside the fabric by roller pressing and drying. The pressure makes the finishing glue fill the gaps in the fabric fibers. At the same time, under the action of the drying temperature, the finishing glue filled in the fabric is solidified in the gaps in the fabric fibers. This process of filling, pressing and drying is a new glue drying method. This method not only ensures the amount of glue concentrated in the gaps in the fabric fibers, but also ensures the bonding strength between the filled glue and the fibers, and finally achieves ultra-thin and efficient anti-down performance, windproof performance and good air permeability.

[0035] Preferably, the mesh density of the anilox roller surface is 60-100 meshes; the coating amount of the post-finishing glue is 5-20 g / m 2 The temperature of the compound machine is 155-165°C, the pressure is 0.05-0.1MPa, and the speed is 30-50m / min.

[0036] More preferably, the present invention uses a high-precision anilox roller to apply glue, and the amount of glue applied is accurately calculated and controlled by the amount of liquid carried by the anilox grooves on the anilox roller, wherein the coating amount of the 100-120 mesh anilox roller is 5-8 g / m 2 , the coating amount of 90-100 mesh anilox roller is 8-10g / m 2 , the coating amount of 70-80 mesh anilox roller is 12-15g / m 2 , the coating amount of 50-60 mesh anilox roller is 18-20g / m 2 .

[0037] Compared with the prior art, the advantages and beneficial effects of the present invention are:

[0038] 1. The present invention forms an incompatible water-in-oil suspension by means of oily glue (oily polyurethane glue solution) and water, which is rolled after micro-concave high-precision coating, and forms a microporous membrane during the drying process. This structure can effectively fill the gaps between fabric fibers, thereby significantly improving the anti-down effect. Compared with traditional calendering or coating treatment, this method can provide better anti-down performance without sacrificing the original properties of the fabric.

[0039] 2. The formation of the micro-nano porous film of the present invention not only enhances the anti-down effect, but also ensures the air permeability and softness of the fabric. This is because the microporous structure allows air circulation, and does not completely close the surface of the fabric like a traditional coating, while avoiding the problem of hardening of the feel caused by hardening of the coating.

[0040] 3. The present invention uses a high-precision anilox roller to apply glue, and can accurately calculate and control the amount of glue applied (5-20 g / m 2 ), which ensures consistent quality every time you process, reduces material waste and improves production efficiency.

[0041] 4. The present invention adopts the process of filling, pressing and drying at the same time, so that the post-finishing glue can be better filled into the gaps of the fabric fibers, and solidified under the action of the drying temperature, thereby enhancing the bonding force between the glue and the fibers. This not only improves the durability of the anti-down effect, but also improves the overall durability of the fabric.

[0042] 5. The present invention selects N,N-dimethylformamide (DMF) as the first organic solvent, which has a higher boiling point than water. N,N-dimethylformamide is an organic solvent compatible with oil and water, and is a high boiling point solvent; the present invention uses a small amount of the solvent to promote the fusion of the amphoteric liquid to form a stable suspended liquid in the early stage of oil-water mixing, and can form micro-nano water liquid particles inside the liquid. After the second solvent evaporates, the overall glue has formed a complete micro-nano sponge-type water droplet structure, and at the same time, there is a certain incompletely solidified property, which is conducive to the discharge of water vapor during subsequent temperature rise, and then forms a transparent micro-nano pore structure membrane, which has a high anti-velvet and high breathability effect. At the same time, DMF can also evaporate at the end of the drying process, reducing the harm to the environment and operators.

[0043] 6. The present invention achieves ultra-thin and efficient anti-down and windproof performance through micro-concave high-precision coating technology and the process of filling, pressing and drying at the same time. This method not only innovates the traditional coating method, but also provides a new solution for the industry, which helps to promote technological progress in the textile industry.

[0076] Application Example 1

[0077] The post-finishing glue prepared in Example 1 is applied to the fabric post-finishing process to obtain a down-proof fabric, and the specific process is as follows:

[0078] The coating surface of the fabric was rolled by the rolling and drying mechanism of the composite machine to achieve the filling of the finishing glue prepared in Example 1 into the gaps between the fabric fibers and to perform rapid drying. Specifically, a 110-mesh anilox roller was used on the composite machine to evenly coat the prepared finishing glue on the coating surface of the fabric. The fabric was 305t 30d polyester pongee, and the glue application amount (i.e., coating amount) was 6g / m 2 The temperature of the laminating machine is 155℃, the speed is 40m / min, and the air-pressure roller is used to roll and dry the surface of the glue-coated fabric. The pressure is 0.1 MPa, and the coated rubber surface is rolled and dried. The surface of the mirror roller in contact with the glue-coated surface is treated with Teflon to prevent it from sticking to the glue. The bottom roller uses a high-temperature resistant silicone roller.

[0079] Application Example 2

[0080] The post-finishing glue prepared in Example 2 is applied to the fabric post-finishing process to obtain a down-proof fabric, and the specific process is as follows:

[0081] The coating surface of the fabric was rolled by the rolling and drying mechanism of the composite machine to achieve the filling of the finishing glue prepared in Example 2 into the gaps between the fabric fibers and rapid drying. Specifically, a 90-mesh anilox roller was used on the composite machine to evenly coat the prepared finishing glue on the coating surface of the fabric. The fabric was 305t 30d polyester pongee, and the glue application amount (i.e., coating amount) was 10g / m 2 The temperature of the laminating machine is 160℃, the speed is 35m / min, and the air pressure roller is used to roll and dry the surface of the glue-coated fabric. The pressure is 0.8 MPa, and the coated glue surface is rolled and dried. The surface of the mirror roller in contact with the glue-coated surface is treated with Teflon to prevent it from sticking to the glue. The bottom roller uses a high-temperature resistant silicone roller.

[0082] Application Example 3

[0083] The post-finishing glue prepared in Example 1 is applied to the fabric post-finishing process to obtain a down-proof fabric, and the specific process is as follows:

[0084] The coating surface of the fabric was rolled by the rolling and drying mechanism of the composite machine to fill the gaps between the fabric fibers with the finishing glue prepared in Example 1 and to dry it quickly. Specifically, a 70-mesh anilox roller was used on the composite machine to evenly coat the prepared finishing glue on the coating surface of the fabric.

[0086] from Figure 6-7 It can be seen that the pore size of the microporous membrane is in the micro-nano pore size, which is much smaller than the thinnest diameter of down, and can play a good breathable and down-proof effect.

[0087] from Figure 8-Figure 9 It can be seen that the present invention fills the internal voids of fabric fibers with micro-nanoporous membranes. Due to the small amount of glue applied, the uncoated surface of the fabric has high down proofing and breathability without any glue penetration pollution, and still maintains the original texture and style of the fabric.

[0088] The performance testing process is as follows:

[0089] The air permeability test was carried out in accordance with GB / T5453-1997 “Determination of air permeability of textile fabrics”, and the anti-down performance test was carried out in accordance with GB / T12705.1-2009 “Test method for anti-down property of textile fabrics Part 1: Friction method”.

[0090] Wash 50 times according to the washing regulations in 10.1.2 of GB / T 20944.3-2008, dry it, and then perform the above air permeability and down proofing tests again. The test results are shown in Table 1.
