[0046] The present invention is described in detail below in conjunction with the accompanying drawings and embodiments.

[0047] Embodiment 1

[0048] like Figure 1 As shown, this embodiment discloses a method for preparing a composite silk polyester fabric, wherein the processed composite silk polyester fabric includes a silk layer 1 and a polyester layer 2, and the silk layer 1 and the polyester layer 2 are compounded by an adhesive layer, wherein the adhesive layer consists of a first adhesive layer 31, a second adhesive layer 32 and a partition layer 33 located between the first adhesive layer 31 and the second adhesive layer 32.

[0049] The production steps of composite silk polyester fabric are as follows:

[0050] S1. Raw material preparation: prepare silk fabric and polyester fabric as raw materials, and then pretreat the silk fabric and polyester fabric.

[0051] Among them, the pretreatment steps of silk fabric are as follows:

[0052] A1. Cleaning: Clean the silk fabric to remove stains and impurities on the surface of the silk fabric;

[0053] A2. Softening treatment: Add softener to water to obtain an aqueous solution, then soak the cleaned silk fabric in the aqueous solution, and after soaking for a set time, perform centrifugal drying treatment;

[0054] A3. Drying: Drying the treated silk fabric to obtain a silk layer 1.

[0055] The pretreatment steps for polyester fabrics are as follows:

[0056] B1. Cleaning: Clean the polyester fabric and remove stains and impurities on the surface of the silk fabric;

[0057] B2. Drying: Drying the cleaned polyester fabric to obtain the polyester layer 2.

[0058] By pretreating the silk fabric and the polyester fabric, the quality and cleanliness of the fabric can be guaranteed, thereby improving the quality of the silk fabric and the polyester fabric after coating the adhesive and hot pressing.

[0059] During the pretreatment of silk fabrics, when the silk fabrics are soaked in softener, ultrasonic equipment can be used to perform ultrasonic treatment on the silk fabrics, thereby enhancing the penetration and effect of the softener on the fabrics.

[0060] In order to make the silk fabric more fluffy after processing, the silk fabric can be placed in an airflow softening finishing machine for expansion treatment before drying to further improve the softness and feel of the fabric.

[0061] S2. Preparation of adhesive: prepare a foaming agent and an adhesive, mix the foaming agent and the adhesive to obtain a mixture, and prepare inorganic salt particles.

[0062] The foaming agent is mixed in the adhesive. During the hot pressing process, the foaming agent will decompose and produce gas when heated. These gases form bubbles in the mixture. When the mixture is coated on the fabric and hot pressed, the bubbles are fixed to form tiny gaps. These gaps can serve as channels for gas circulation, reducing the direct blockage of the fabric pores by the adhesive, and effectively improving the air permeability of the two layers of fabric after hot pressing.

[0063] S3, fabric compounding: the mixture in S2 and the silk fabric and polyester fabric in S1 are placed on a hot pressing compounding device to prepare the silk layer and the polyester layer; then the hot pressing compounding device is started, a layer of the mixture is firstly coated on the upper surface of the silk layer to form a first adhesive layer 31, and then inorganic salt particles are sprayed on the upper surface of the mixture to form a separation layer 33, and finally a layer of the mixture is coated on the surface of the inorganic salt particles to form a second adhesive layer to obtain a complete adhesive layer; finally, the polyester layer is bonded to the silk layer through the adhesive layer by the hot pressing compounding device to obtain a composite silk polyester fabric.

[0064] During the production process, a layer of a mixture of an adhesive and a foaming agent is first applied on the upper surface of the silk fabric, and then a layer of inorganic salt particles is evenly sprayed on the surface of the first mixture, and then the mixture is applied again, so that the inorganic salt particles are wrapped between the two layers of the mixture. After the second adhesive coating is completed, during the fabric conveying process, the scraper 21 will scratch a conical air groove 34 on the adhesive layer, so that during the hot pressing process of the fabric, the inorganic salt particles will not melt or deform significantly, but will maintain their granular state, providing a certain structural support for the adhesive layer; and it also plays a role in separating the adhesive to prevent the adhesive from continuously and densely clogging the pores of the fabric, allowing the gaps between the particles to allow gas to flow. Compared with the existing production steps of directly compounding two layers of fabric through a layer of adhesive, the process steps of the present application can further improve the air permeability of the fabric; and the setting of the air groove 34 can ensure that during the hot pressing process, a certain gap can be formed between the adhesive layer and the side of the polyester cloth that is bonded to ensure the air permeability effect.

[0065] S4, cooling and shaping: cooling and shaping the composite fabrics in S3; when the composite fabrics are being transported, the adhesive can be quickly solidified by natural cooling or by adding a fan on one side for air cooling, thereby ensuring rapid bonding between the two layers of fabrics.

[0066] S5, winding and finishing: the fabric after cooling and setting is wound up. During this process, there is a winding roller 91 at the end of the hot pressing laminating machine, and the winding roller 91 can wind up and finish the cooled fabric.

[0067] Embodiment 2

[0068] like Figure 2-3 As shown, in order to realize the production steps of Example 1, this embodiment provides a production equipment for composite silk polyester fabrics, which is a hot pressing composite equipment, including a frame 4 with a conveying mechanism 5 and a control module, and the frame 4 is provided with an unwinding mechanism 6 connected to the control module, a first coating mechanism 10, a spraying mechanism 7, a second coating mechanism 11, a hot pressing composite mechanism 8, and a winding mechanism 9 in sequence along the conveying direction of the conveying mechanism 5.

[0069] like Figure 3 As shown, the conveying mechanism 5 is a plurality of conveying rollers and a traction roller group arranged on the feeding channel of the frame 4. The traction roller group is driven by a motor. The traction roller group includes a first traction roller group 51 for traction of silk fabrics and a second traction roller group 52 for conveying polyester fabrics. The first traction roller group 51 and the second traction roller group 52 are both arranged before the hot pressing composite mechanism 8, and after the hot pressing composite traction mechanism, a third traction roller group 53 for traction of composite silk polyester fabrics is also arranged. The third traction roller group 53 conveys the composited fabrics to the winding mechanism 9, so that the winding mechanism 9 winds and arranges the fabrics.

[0070] The unwinding mechanism 6 is two unwinding rollers 61 rotatably arranged on the frame 4. The unwinding rollers 61 passively rotate during the movement of the fabric, thereby realizing the release of the fabric.

[0071] like Figure 4-6 As shown, the spraying mechanism 7 located between the first coating mechanism 10 and the second coating mechanism 11 includes a material box 71 arranged on the frame 4, and the material box 71 is provided with a discharge port and a nozzle 72. The nozzle 72 is connected to the material box 71 through a suction pipe 73. The nozzle 72 is also connected to an air pipe 74, and the air pipe 74 is vertically arranged to the suction pipe 73 and one end of the air pipe 74 is connected to an air intake pump 75. The air intake pump 75 can blow air into the nozzle 72 through the air pipe 74, and then discharge it from the nozzle 72. When the airflow passes through the suction pipe 73, it will generate suction on the material in the material box 71, so that the inorganic salt particles in the material box 71 are sucked into the nozzle 72 and then sprayed by the nozzle 72 to the adhesive surface on the upper surface of the silk fabric, so as to realize the spraying of the adhesive surface.

[0072] like Figure 6 As shown, in order to allow the inorganic salt particles to be smoothly discharged by the straw 73, the straw 73 can adopt a U-shaped structure, and the inorganic salt particles will accumulate at the bending part of the U, so that the particles can be sprayed out more easily.

[0073] like Figure 3 As shown, the hot pressing composite mechanism 8 is a prior art, which is two heating rollers 81 rotatably connected to the frame 4 and rotating towards each other. The heating rollers 81 are provided with heating components, which can heat the heating rollers 81; and when the silk fabric and the polyester fabric pass through the two heating rollers 81, they will be heated and close to each other, thereby realizing the mutual composite between the silk fabric and the polyester fabric.

[0074] The winding mechanism 9 is a winding roller 91 which is rotatably arranged on the frame 4 and connected to a motor at one end. There is a certain distance between the winding roller 91 and the hot pressing composite mechanism 8, which can allow the composited fabric to be naturally cooled. In order to speed up the cooling speed, the staff can add a fan on the moving path of the fabric to achieve cooling.

[0075] like Figure 5 As shown, the first coating mechanism 10 and the second coating mechanism 11 for coating the adhesive layer on the upper surface of the silk fabric both include a material box 13 arranged on the frame 4 and having a heating component, the material box 13 is provided with a feed port 14 and a discharge port 15, the discharge port 15 is connected to a material guide pipe 16, the material guide pipe 16 is connected to a glue coating head 17; the glue coating head 17 includes a material extrusion box 18 connected to the material guide pipe 16, the material extrusion box 18 is provided with a glue outlet on the side opposite to the fabric, and a guide pipe 19 is provided at the glue outlet.

[0076] The material box 13 is provided with two glue coating heads 17 connected to the bottom through two discharge ports 15 and two material guide pipes 16. The two glue coating heads 17 are respectively located on both sides of the spraying mechanism 7. When the equipment is working, the staff can first add the mixture of the foaming agent and the adhesive into the material box 13, and a heating component is provided in the material box 13. The heating component can be an electric heating wire that can heat the mixture in the material box 13 to make it in a fluid gel state. The gel-like mixture will enter the glue coating head 17 along the material guide pipe 16, and then flow along the glue coating head 17 to the upper surface of the silk fabric to achieve gluing.

[0077] The guide tube 19 is inclined toward the movement direction of the silk fabric, and a scraper plate 20 is formed on the outer wall of one side of the guide tube 19 extending downward toward the silk fabric. The inclined guide tube 19 can guide the adhesive, facilitating the adhesive to flow evenly onto the silk fabric, and the scraper plate 20 can smooth and evenly spread the adhesive coated on the upper surface of the silk fabric to prevent the adhesive from being too thick and affecting the air permeability of the fabric.

[0078] like Figure 7 As shown, the second coating mechanism 11 is provided with a plurality of guide tubes 19, which are spaced apart in a straight line along the width direction of the silk fabric. The spaced apart guide tubes 19 can form spaced apart adhesive layers on the surface of the inorganic salt particles. The spaced apart adhesive layers can form gaps between the first adhesive layers, thereby ensuring that during the hot pressing composite process, the colloidal adhesive layer will not completely cover the surface of the inorganic salt particles and block the pores on the surface of the fabric.

[0079] A scraper 21 is protruding from the lower end of the scraper plate 20 of the second coating mechanism 11. When the scraper 21 passes through the adhesive layer, an air groove 34 structure is formed on the surface of the adhesive layer. The structure of the air groove 34 can form a gap between the adhesive layer and the polyester fabric during hot pressing and compounding, thereby further improving the air permeability. The cross-section of the scraper 21 is a trapezoidal structure that is small at the top and large at the bottom.

[0080] like Figure 8As shown, a pair of squeezing rollers 181 located on both sides of the glue outlet are rotatably arranged in the extrusion box 18, and the pair of squeezing rollers 181 rotate in opposite directions through gear meshing, and a plurality of squeezing sheets 182 are extended outward from the circumference of the squeezing rollers 181; a motor is also included which is arranged on the extrusion box 18 and connected to the end of one squeezing roller 181; when the gel-like mixture flows from the material box 13 into the extrusion box 18, the squeezing roller 181 will rotate under the drive of the motor and drive another squeezing roller to rotate in opposite directions through the gear, and the squeezing roller 181 will drive the squeezing sheet 182 to drive the mixture toward the glue outlet, thereby realizing the discharge of the mixture, and when the equipment stops, the pair of squeezing rollers 181 stop rotating, and the gel-like mixture will stop discharging due to the loss of squeezing force.

[0081] The motor, air intake pump 75, heating assembly and other structures involved in the above structure are all electrically connected to the control module and controlled by the control module of the equipment.

[0082] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
