Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of three-proof and easy-to-clean windbreaker fabrics, specifically to a three-proof and easy-to-clean windbreaker fabric that can be washed and dried. Background Technology
[0002] Existing traditional three-proof fabrics mostly use fluorinated finishing agents (such as PFAS derivatives) to coat or pad the fabric, providing excellent initial three-proof performance (waterproof, oilproof, and stainproof). However, after repeated washing, the molecular chains of the finishing agents break or fall off from the fiber surface, leading to performance degradation (performance decreases by more than 50% after 5-10 washes). Restoring performance requires high-temperature ironing (≥150℃) or drying, which is energy-intensive and damages the fabric's shape. Current technology cannot achieve rapid, low-loss, and long-lasting performance self-repair after washing without external high-energy input.
[0003] Moreover, while existing windbreaker fabrics using double-sided high-density materials offer strong wind protection, they also tend to be stuffy and hot. Summary of the Invention
[0004] In order to overcome the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a windbreaker fabric that is easy to clean, three-proof, and stain-resistant after washing and drying.
[0005] The purpose of this utility model is achieved through the following technical solution: a three-proof and easy-to-clean windbreaker fabric that can be washed and dried, comprising a high-density woven structure layer and a microchannel mesh layer that are sequentially bonded from the outside to the inside, wherein the fabric is impregnated to form a self-healing three-proof and easy-to-clean layer that is attached to the high-density woven structure layer and the microchannel mesh layer, and the microchannel mesh layer has honeycomb-shaped microchannels evenly distributed thereon.
[0006] Preferably, the high-density woven structural layer is 100D polyester filament plain weave fabric or 70D nylon taslan.
[0007] Preferably, the porosity of the high-density woven structure layer is 8-12%.
[0008] Preferably, the microchannel mesh layer is a 50D cotton / polyester staple fiber blended honeycomb fabric or a 30D nylon mesh fabric.
[0009] Preferably, the diameter of the honeycomb microchannels in the microchannel network layer is 20-80 μm, and the specific surface area is 6-7.5 m² / g.
[0010] Preferably, the self-healing, three-proof, and easy-to-clean agent for the three-proof layer is a drying-responsive three-proof agent, and the dynamic contact angle change rate of the drying-responsive three-proof agent is >50%.
[0011] Preferably, the drying-responsive three-proof additive is Rudolf C6 fluorocarbon modified polyurethane RUCO 1146.
[0012] The beneficial effects of this utility model are as follows: The three-proof and easy-to-clean windbreaker fabric of this utility model adopts a high-density woven structure layer and a microchannel mesh layer that are sequentially bonded from the outside to the inside. The fabric is impregnated to form a self-healing three-proof and easy-to-clean layer attached to the high-density woven structure layer and the microchannel mesh layer. The microchannel mesh layer has honeycomb-shaped microchannels evenly distributed. This windbreaker fabric has durable three-proof (waterproof, oil-proof, and stain-proof) and easy-to-clean properties, and is especially suitable for outdoor clothing, workwear, and everyday outerwear. Its innovation lies in the "gradient microchannel fabric structure" design, which combines the self-healing three-proof and easy-to-clean layer with the high-density woven structure layer and the microchannel mesh layer. The synergistic effect allows the fabric to automatically restore its three-proof and easy-to-clean properties after washing and air drying, without the need for additional ironing or tumble drying, making it more energy-efficient and convenient. In addition, the microchannel mesh layer has honeycomb-shaped microchannels evenly distributed, which helps maintain the breathability of the microchannel mesh layer. Compared with traditional double-sided high-density fabrics, this solution uses a double-sided heterogeneous fabric design that combines a high-density woven structure layer and a microchannel mesh layer, which helps to improve the stuffiness of the close-fitting side while maintaining the windproof effect of the outer surface. Attached Figure Description
[0013] Figure 1 This is an exploded structural diagram of the present invention; The attached diagram is labeled as follows: 1. High-density woven structure layer; 2. Microchannel mesh layer; 3. Honeycomb microchannels. Detailed Implementation
[0014] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.
[0015] like Figure 1 As shown, a three-proof and easy-to-clean windbreaker fabric that can be washed and dried includes a high-density woven structure layer 1 and a microchannel mesh layer 2 bonded together from the outside to the inside. The fabric is impregnated to form a self-healing three-proof and easy-to-clean layer attached to the high-density woven structure layer 1 and the microchannel mesh layer 2. The microchannel mesh layer 2 has honeycomb-shaped microchannels 3 evenly distributed.
[0016] This windbreaker fabric boasts durable three-proof (waterproof, oil-proof, and stain-resistant) properties and easy stain removal, making it particularly suitable for outdoor clothing, workwear, and everyday outerwear. Its innovation lies in its "gradient microchannel fabric structure" design, which combines a self-healing, three-proof, and easy-to-clean layer with a high-density woven structure layer 1 and a microchannel mesh layer 2. This synergistic effect allows the fabric to automatically regain its three-proof and easy-to-clean properties after washing simply by air drying, eliminating the need for ironing or tumble drying, thus saving energy and offering greater convenience. Furthermore, the microchannel mesh layer 2 features evenly distributed honeycomb microchannels 3, which helps maintain its breathability. Compared to traditional double-sided high-density fabrics, this design, with its double-sided heterogeneous fabric combining a high-density woven structure layer 1 and a microchannel mesh layer 2, helps mitigate the stuffiness of the inner surface while maintaining windproof performance on the outer layer.
[0017] Furthermore, the high-density woven structural layer 1 is a 100D polyester filament plain weave fabric or a 70D nylon taslon fabric. In this embodiment, the high-density woven structural layer 1 is a 100D polyester filament plain weave fabric. In another embodiment, the high-density woven structural layer 1 is a 70D nylon taslon fabric.
[0018] Furthermore, the high-density woven structure layer 1 has a porosity of 8-12%. On one hand, it maintains the windproof effect of the fabric surface; on the other hand, due to the migration of the three-proof and easy-to-clean agents in the self-healing three-proof and easy-to-clean layer during the fabric impregnation process, after pre-drying at 110℃ for 2 minutes and setting at 160℃ for 1 minute, the agents are cross-linked and fixed onto the fabric fibers. The high-density woven structure layer 1 with a porosity of 8-12% helps to lock in the three-proof and easy-to-clean agent molecules, preventing excessive loss during washing. After 30 standard washes (AATCC 61-2A standard), the three-proof performance and easy-to-clean performance retain ≥80%. In this embodiment, the porosity of the high-density woven structure layer 1 is 8%. In another embodiment, the porosity of the high-density woven structure layer 1 is 12%.
[0019] Furthermore, the microchannel mesh layer 2 is a 50D cotton / polyester staple fiber blended honeycomb fabric or a 30D nylon mesh fabric. In this embodiment, the microchannel mesh layer 2 is a 50D cotton / polyester staple fiber blended honeycomb fabric. In another embodiment, the microchannel mesh layer 2 is a 30D nylon mesh fabric.
[0020] Furthermore, the honeycomb microchannels 3 of the microchannel mesh layer 2 have a diameter of 20-80 μm and a specific surface area of 6-7.5 m² / g. The honeycomb microchannels 3 accelerate the directional evaporation of moisture through capillary effect, speeding up fabric drying. After washing, the fabric can be restored to its three-proof and easy-to-clean properties simply by air drying (room temperature, ≤8 hours). In this embodiment, the diameter of the honeycomb microchannels 3 of the microchannel mesh layer 2 is between 20-50 μm, and the specific surface area is 6.2 m² / g. In another embodiment, the diameter of the honeycomb microchannels 3 of the microchannel mesh layer 2 is between 30-80 μm, and the specific surface area is 7.5 m² / g.
[0021] Furthermore, the self-healing, three-proof, and easy-to-clean agent for the three-proof layer is a drying-responsive three-proof additive. The dynamic contact angle change rate of the drying-responsive three-proof additive is >50%, and the contact angle is tested according to GB / T 30693. Specifically, in the wet state (contact angle <90°): the hydrophilic end of the drying-responsive three-proof additive is exposed, which facilitates the release of contaminating substances during washing; in the dry state (contact angle >130°): the hydrophobic chain of the drying-responsive three-proof additive spontaneously flips and recombines to form a dense protective layer.
[0022] Furthermore, in this embodiment, the drying-responsive three-proof additive is Rudolf C6 fluorocarbon modified polyurethane RUCO 1146, which has a wet contact angle of 78°, a dry contact angle of 143°, and a dynamic contact angle change rate of 83%, meeting the performance requirements of drying-responsive three-proof additives and ensuring that molecular self-repair is triggered during the drying process. This is existing technology and is only used as an application here.
[0023] This embodiment utilizes the dynamic coupling of physical structure (honeycomb microchannels 3) and chemical response (dynamic contact angle change of the drying-responsive three-proof additive). During the washing stage of the windbreaker fabric, water penetrates into the honeycomb microchannels 3, while the hydrophilic end of the drying-responsive three-proof additive is exposed, assisting in the dissolution and release of contaminated substances. During the drying stage of the windbreaker fabric, the honeycomb microchannels 3 generate capillary force to accelerate water evaporation (rate ≥0.38 g / (m²)). 2 The contact angle of the three-proof additive, triggered by moisture evaporation and drying response, undergoes a sudden change, causing the hydrophobic chain to reverse in an oriented manner and self-recover into a continuous molecular film, forming a dense protective layer to achieve the effect of three-proof and easy stain removal; after drying at room temperature for 6 hours, the water / oil repellency recovery rate is ≥80% (after 30 washes); the stain residue rate is reduced to 4% (peanut oil, ISO 15797).
[0024] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this utility model are within the protection scope of this utility model.
