Description

Technical Field

[0001] This invention relates to the field of fabric processing technology, and in particular to a processing technology for a warm and windproof fabric. Background Technology

[0002] As people's living standards continue to improve, their demands for daily necessities are also increasing, with clothing being one of the most common necessities. The most basic function of clothing is to protect the body; it prevents external harm and maintains body temperature. In the cold winter, wearing thick down jackets and sweaters effectively protects the body from the cold.

[0003] As people's quality of life improves, they also have higher and higher requirements for the functionality of clothing fabrics. Most warm and windproof fabrics, while meeting basic living needs, no longer have other functions, thus limiting their multifunctionality and failing to meet people's multifunctional needs for clothing. Summary of the Invention

[0004] This invention discloses a processing technology for a warm and windproof fabric, aiming to solve the technical problem that the multifunctionality of ordinary fabrics is limited and cannot meet people's multifunctional needs for clothing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A processing technology for a warm and windproof fabric includes the following specific steps:

[0007] S1: Coating Immersion: Immerse the surface fabric in waterproof coating and then dry the surface.

[0008] S2: Filling: Guiding the outer and inner layers of fabric and filling them with down using a filling device.

[0009] S3: Integrated sewing: After the outer layer, inner layer and down filling layer are integrated and guided by the down filling equipment, the three are sewn together in an interlaced manner by the sewing equipment;

[0010] S4: Static electricity removal: Using equipment to remove static electricity attached to the fabric;

[0011] S5: Packaging and storage;

[0012] The down filling device in S2 includes a down filling mechanism and a smoothing mechanism. The down filling mechanism includes a first roller conveyor group and a second roller conveyor group. The inner layer and the outer layer are simultaneously sandwiched between the first roller conveyor group and the second roller conveyor group. An electrostatic plate is provided in the middle of the first roller conveyor group. A support frame is fixedly connected to the top of the electrostatic plate, and the bottom of the electrostatic plate is attached to the surface of the inner layer. A down filling groove is provided in the middle of the second roller conveyor group, and a base frame is connected to the bottom of the second roller conveyor group and the down filling groove. An antistatic plate is fixedly connected to the inner wall of the bottom of the down filling groove, and openings are provided through the inner walls on opposite sides of the down filling groove. The outer layer passes through the two openings and is attached to the surface of the antistatic plate. First vents are provided through the inner walls on the other two sides of the down filling groove, and the first vents are higher than the opening positions. The two first vents are respectively tightly connected to a blower channel and a suction channel.

[0013] By incorporating a down filling mechanism, the inner layer becomes statically charged under the action of an electrostatic plate and an antistatic plate, while the surface layer is destatically removed. Thus, during the process of introducing down into the down filling trough through the air duct, the down can be evenly adsorbed onto the inner wall of the inner layer. Under the action of residual static electricity, the down is stably adhered to the inner layer. Guided and clamped by the roller conveyor group, the inner layer and the surface layer are stacked together, completing the down filling process. This structure can ensure the uniformity of down filling while further ensuring the balance of down filling amount within a single down filling unit. It also avoids down flying away and causing waste during the stacking process due to residual static electricity.

[0014] In a preferred embodiment, the outer layer of the warm and windproof fabric is covered with a waterproof coating, and the inner and outer layers are filled with down filling layers. Multiple horizontal and vertical sewing lines are staggered on both the inner and outer layers, and the horizontal and vertical sewing lines are divided into multiple consistent filling units.

[0015] Similar to existing fabrics, this windproof fabric, consisting of an inner layer, an outer layer, and a down filling layer, achieves its windproof and waterproof effects by applying a waterproof coating to the outer layer. It provides warmth by filling the inner and outer layers with down. However, unlike existing fabrics, both the outer and inner layers are woven from long-staple cotton. Long-staple cotton, with its superior thermal expansion and contraction properties, is typically used as a filling material, exhibiting varying degrees of compactness depending on temperature for enhanced warmth. However, its warmth retention is not as good as down filling. Therefore, the outer and inner layers, woven from long-staple cotton, simultaneously possess thermal expansion and contraction properties. Multiple filling units can adjust the volume of the inner and outer layers within a single filling unit according to temperature changes during thermal expansion and contraction, thus providing different levels of warmth and making the fabric more functionally versatile.

[0016] In a preferred embodiment, the smoothing mechanism includes a smoothing conveyor belt that is attached to the inner and outer layers. One side of the smoothing conveyor belt is connected to a ventilation groove via a connecting frame. A second ventilation port is provided through the top and bottom of the ventilation groove. Ventilation pipes are tightly connected to the inner walls of the opposing sides of the ventilation groove, and the two ventilation pipes are respectively connected to a ventilation system. A condenser plate is fixedly connected to the middle of the inner wall of the ventilation groove, and air-breaking plates are fixedly connected to both ends of the condenser plate.

[0017] By incorporating a smoothing mechanism, air is introduced into the air duct through vents on both sides during the inner and outer layer conveying process. Upon contact with the condenser plate, cold air is generated and acts on the inner and outer layers respectively, allowing the fabric to be filled with down in a cooler, contracted state. This facilitates control of the amount of down filling during the contracted state. The smoothing conveyor belt also ensures smoothness during the filling and fabric stacking process by smoothing the fabric to opposite sides.

[0018] As can be seen from the above, the processing technology of a warm and windproof fabric includes the following specific steps: S1: Coating soaking: The surface fabric is soaked in a waterproof coating and then dried; S2: Filling: The surface and inner fabrics are guided and filled with down through a filling device; S3: Integration and sewing: After the surface, inner, and filling layers are integrated and guided by the filling device, they are sewn together using a sewing device; S4: Static removal: Static electricity on the fabric is removed using equipment; S5: Packaging and storage; The filling device in S2 includes a filling mechanism and a smoothing mechanism, and the filling mechanism includes a first roller conveyor group and a second roller conveyor group, with the inner and surface layers held together simultaneously. Between the first and second roller conveyor groups, an electrostatic plate is disposed in the middle of the first roller conveyor group; a support frame is fixedly connected to the top of the electrostatic plate, and the bottom of the electrostatic plate is attached to the surface of the inner layer. A down filling groove is disposed in the middle of the second roller conveyor group, and a base frame is connected to the bottom of both the second roller conveyor group and the down filling groove; an antistatic plate is fixedly connected to the inner wall of the bottom of the down filling groove, and openings are provided through the opposite inner walls of the down filling groove, with the surface layer passing through the two openings and attached to the surface of the antistatic plate; first vents are provided through the inner walls of the other two sides of the down filling groove, and the first vents are higher than the opening positions, with the two first vents respectively tightly connected to a blower channel and a suction channel. The warm and windproof fabric and its processing technology provided by the present invention have the technical effect of ensuring the uniformity of down filling in a single down filling unit, and also avoiding waste of down during the stacking process due to residual static electricity.

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] The processing technology for a warm and windproof fabric disclosed in this invention is mainly applied to fabric processing scenarios.

[0028] Reference Figure 6 A processing technology for a warm and windproof fabric includes the following specific steps:

[0029] S1: Coating Immersion: Immerse the fabric of surface layer 5 in waterproof coating 6 and dry surface layer 5;

[0030] S2: Filling: Guiding the fabric of the outer layer 5 and the inner layer 1, and filling the fabric between the outer layer 5 and the inner layer 1 using a filling device:

[0031] S3: Integrated sewing: After the outer layer 5, inner layer 1 and down filling layer 4 are integrated and guided by the down filling equipment, the three are sewn together in an interlaced manner by the sewing equipment;

[0032] S4: Static electricity removal: Using equipment to remove static electricity attached to the fabric;

[0033] S5: Packaging and storage.

[0034] Reference Figure 2 and Figure 3 In a preferred embodiment, the down filling device in S2 includes a down filling mechanism 7 and a smoothing mechanism 8. The down filling mechanism 7 includes a first roller conveyor group 703 and a second roller conveyor group 706. The inner layer 1 and the outer layer 5 are simultaneously sandwiched between the first roller conveyor group 703 and the second roller conveyor group 706. An electrostatic plate 702 is provided in the middle of the first roller conveyor group 703.

[0035] Reference Figure 3 In a preferred embodiment, a support frame 701 is fixedly connected to the top of the electrostatic plate 702, and the bottom of the electrostatic plate 702 is attached to the surface of the inner layer 1. A down filling groove 708 is provided in the middle of the second roller conveyor group 706, and the bottom of the second roller conveyor group 706 and the down filling groove 708 are connected to a base frame 710.

[0036] Reference Figure 3 In a preferred embodiment, an antistatic plate 709 is fixedly connected to the bottom inner wall of the down filling groove 708, and through openings 707 are provided on the opposite inner walls of the down filling groove 708. The surface layer 5 passes through the two through openings 707 and is attached to the surface of the antistatic plate 709.

[0037] Reference Figure 3In a preferred embodiment, the inner walls on both sides of the down filling groove 708 are provided with first vents 705, and the first vents 705 are higher than the opening 707. The two first vents 705 are respectively tightly connected to the blower channel 704 and the suction channel 711. In the down filling mechanism 7, the surface layer 5 and the inner layer 1 are guided by the first roller conveyor group 703 and the second roller conveyor group 706. When passing through the down filling groove 708, under the action of the electrostatic plate 702 and the antistatic plate 709, the inner layer 1 becomes statically charged, and the surface layer 5 is destatically removed. Thus, the down filling mechanism 7 guides the surface layer 5 and the inner layer 1 through the blower channel 704 and the suction channel 711, respectively. Down is introduced into the down filling trough 708 through the air duct 704. During the process of the down being drawn in by the suction duct 711, the down is evenly adsorbed onto the inner wall of the inner layer 1 by the electrostatic adsorption of the inner layer 1. Under the action of residual static electricity, the down is stably adhered to the inner layer 1. Guided and clamped by the roller conveyor group, the inner layer 1 is stacked with the outer layer 5 to complete the down filling. Under this structure, while ensuring the uniformity of down filling, the balance of down filling amount in a single down filling unit can be further ensured. Under the action of residual static electricity, down flying during the stacking process is also avoided, which causes waste.

[0038] Reference Figure 1 In a preferred embodiment, the outer layer 5 of the warm and windproof fabric is covered with a waterproof coating 6, and the inner layer 1 and the outer layer 5 are filled with down filling layers 4. Multiple horizontal and vertical sewing lines 2 and 3 are interlaced on the inner layer 1 and the outer layer 5, and the horizontal and vertical sewing lines 2 and 3 divide the fabric into multiple consistent filling units. Similar to existing fabrics, this windproof fabric achieves windproof and waterproof effects by covering the outer layer 5 with a waterproof coating 6, and achieves warmth by filling the inner layer 1 and the outer layer 5 with down. However, unlike existing fabrics, both the outer layer 5 and the inner layer 1 are woven from long-staple cotton. Long-staple cotton has excellent thermal expansion and contraction properties and is generally used as filling material. It exhibits different levels of compactness depending on the temperature, achieving a better warmth effect. However, the warmth retention effect of long-staple cotton is not as good as that of down filling. The fleece filling, combined with the outer layer 5 and inner layer 1 woven from long-staple cotton, allows for both thermal expansion and contraction. Since the waterproof coating 6 also exhibits thermal expansion and contraction properties, it does not affect the deformation of the outer layer 5. Multiple filling units, reinforced by transverse and longitudinal sewing lines 2 and 3, maintain an unchanged filling framework during thermal expansion and contraction. The volume of the inner layer 1 and outer layer 5 within each individual filling unit can be adjusted according to temperature changes. Thus, in warm weather, the fleece volume can be increased to reduce the fleece ratio, making it more breathable and suitable for warmer temperatures, preventing overheating. In cold weather, the fleece volume can be reduced to increase the fleece ratio, providing greater warmth. This allows for different levels of insulation based on temperature changes, making the fabric more functionally versatile.

[0039] Reference Figure 4 and Figure 5In a preferred embodiment, the smoothing mechanism 8 includes a smoothing conveyor belt 802, which is attached to the inner layer 1 and the outer layer 5. One side of the smoothing conveyor belt 802 is connected to a ventilation groove 804 via a connecting frame 801, and a second ventilation port 806 is provided through the top and bottom of the ventilation groove 804.

[0040] Reference Figure 4 and Figure 5 In a preferred embodiment, ventilation pipes 803 are tightly connected to the inner walls of the ventilation groove 804 on both sides, and the two ventilation pipes 803 are respectively connected to a ventilation system. A condenser plate 807 is fixedly connected to the middle of the inner wall of the ventilation groove 804, and air-breaking plates 805 are fixedly connected to both ends of the condenser plate 807. In the smoothing mechanism 8, during the conveying of the inner layer 1 and the outer layer 5, air is vented into the ventilation groove 804 by the ventilation pipes 803 on both sides. Under the action of the air-breaking plates 805, the air is broken and exhaust is discharged from the two second ventilation ports 806 at the upper and lower ends. When the air contacts the condenser plate 807, cold air is formed and acts on the inner layer 1 and the outer layer 5 respectively, so that the fabric is filled in a colder shrinkage state, which makes it easier to control the amount of filling in the shrinkage state. After shrinkage by cold air, the smoothing conveyor belt 802 smooths the fabric to both sides, which can effectively avoid wrinkling of the fabric during the guidance process after shrinkage and ensure the smoothness of filling and fabric stacking.

[0041] Working principle: Similar to existing fabrics, this windproof fabric achieves windproof and waterproof effects by covering the outer layer 5 with a waterproof coating 6, and achieves warmth by filling the inner layer 1 and the outer layer 5 with down. The difference is that both the outer layer 5 and the inner layer 1 are woven from long-staple cotton. Long-staple cotton has excellent thermal expansion and contraction properties and is generally used as filling, exhibiting different levels of compactness depending on the temperature to achieve a better warmth effect. However, the warmth retention of long-staple cotton is not as good as down filling. Therefore, the outer layer 5 and the inner layer 1, woven from long-staple cotton, both possess thermal expansion and contraction properties. Since the waterproof coating 6 also has thermal expansion and contraction properties, it does not affect the deformation of the outer layer 5. The multiple filling units, reinforced by sewing thread 2 and longitudinal sewing thread 3, can change the volume of the inner layer 1 and outer layer 5 within a single filling unit according to temperature changes, while maintaining the filling frame unchanged during thermal expansion and contraction. Thus, in warm weather, the filling volume is increased to reduce the filling ratio, making it more breathable and suitable for warmer temperatures, preventing overheating. In cold weather, the filling volume is reduced to increase the filling ratio, making it warmer. This provides different warmth effects according to temperature changes, making the fabric more functionally versatile. Simultaneously, in the filling mechanism 7, the first roller conveyor group 703 and the second roller conveyor group 706 feed the outer layer 5 and inner layer 1... As the down is guided through the filling trough 708, the inner layer 1 becomes statically charged under the action of the electrostatic plate 702 and the antistatic plate 709, while the surface layer 5 is destaticated. Thus, as down is introduced into the filling trough 708 through the blowing channel 704 and drawn in through the suction channel 711, the down is evenly adsorbed onto the inner wall of the inner layer 1 by the electrostatic adsorption of the inner layer 1. Under the influence of residual static electricity, the down is stably adhered to the inner layer 1. Guided and clamped by the roller conveyor group, the inner layer 1 and the surface layer 5 are overlapped, completing the filling process. This structure ensures both uniform filling and balanced filling volume within a single filling unit, while also mitigating the effects of residual static electricity. To avoid waste caused by down flying during the stacking process, in addition, in the smoothing mechanism 8, during the conveying of the inner layer 1 and the outer layer 5, air is introduced into the air groove 804 through the air pipes 803 on both sides. Under the action of the air breaker 805, the air is broken and exhausted from the two second air ports 806 at the upper and lower ends. When it comes into contact with the condenser plate 807, cold air is formed and acts on the inner layer 1 and the outer layer 5 respectively, so that the fabric is filled with down in a contracted state at a relatively cold temperature. This makes it easier to control the amount of down filling in the contracted state. After the cold air contraction, the smoothing conveyor belt 802 smooths the fabric to both sides, which can effectively avoid the fabric from wrinkling during the guidance process after contraction, and ensure the smoothness of the down filling and fabric stacking process.
