Description

Technical Field

[0001] This invention belongs to the field of protective clothing, specifically relating to a breathable and warm protective clothing. Background Technology

[0002] Breathable protective suits are a type of skin protection equipment used by both military and civilian sectors that allows air and moisture to pass through while preventing harm from toxic gases, bacteria, and radioactive dust. They can be used in conjunction with other protective gear to provide full-body protection against chemical agents. However, existing breathable protective suits suffer from poor windproofing and warmth retention when operating in cold regions. This is because their poor breathability prevents the evaporation of sweat vapor produced by the body. To address this issue, this invention proposes a protective suit that improves breathability through material selection and incorporates an added insulating layer in its structural design, resulting in a suit with excellent toxic agent protection, good breathability, and windproof and warmth retention. Summary of the Invention

[0003] The purpose of this invention is to provide a protective suit to solve the technical problem that existing protective suits have poor breathability and the sweat vapor produced by the human body cannot evaporate, resulting in poor windproof and warmth retention.

[0004] To achieve the above objectives, the present invention provides a protective clothing material, comprising an outer layer and an inner layer; the outer layer is a functional layer for providing flame retardant, water-repellent, oil-repellent, and breathable functions; the inner layer is a protective layer for providing both protective and breathable functions. Optionally, the outer layer is a fabric that has been treated with flame retardancy, water repellency and oil repellency, and has high breathability through optimized weaving parameters; the middle layer includes a protective layer made of carbon fiber material.

[0005] Optionally, the intermediate layer further includes a skeleton layer for supporting the protective layer, the skeleton layer being flame-retardant treated cotton fabric.

[0006] In another aspect, the present invention provides a protective suit, which includes a one-piece protective hood and a main body of the protective suit.

[0007] Optionally, the protective suit may also include a detachable thermal liner, which is made of double-sided fleece material.

[0008] Optionally, the protective hood is equipped with elastic tightening elements at the face opening and neck area to ensure a tight fit with the gas mask and the human body.

[0009] Optionally, the main body of the protective suit is equipped with a waist adjustment structure, a double-layer closed front, and adjustable cuffs and trouser legs.

[0010] Optionally, the thermal liner includes an upper garment and trousers, which are connected to the inside of the protective suit body via hook and loop fasteners; the cuffs, leg openings, and waist of the upper garment and trousers are provided with elastic tightening structures.

[0011] Optionally, the garment is equipped with an anti-slip cuff structure and a smooth zipper closure structure.

[0012] Optionally, the protective clothing has an air permeability of not less than 100 mm / s and a protection time against toxic agents of not less than 24 hours.

[0013] The protective suit provided by this invention has the following outermost layers: The outermost layer is a functional layer made of fabric specially treated for flame retardancy, water repellency, and oil repellency. Optimized weaving parameters ensure extremely high breathability, effectively blocking external liquid threats while allowing sweat vapor generated by the body to escape smoothly. The middle layer is the protective layer, with its core protective layer being a lightweight, highly absorbent carbon fiber material. This protective layer, while maintaining excellent breathability, can efficiently absorb and block chemical agents, bacteria, and radioactive dust. Simultaneously, a skeleton layer composed of flame-retardant cotton fabric provides support and protection for the protective layer, enhancing durability and comfort. The innermost layer is a thermal layer made of double-sided fleece material with good moisture-wicking and quick-drying properties. It can quickly absorb and dry sweat from the skin's surface, preventing a damp and cold feeling caused by sweat accumulation, and effectively locking in body heat inside the garment, creating a warm microclimate.

[0014] Based on this, the one-piece protective hood provided by this invention ensures a tight fit between the protective suit and the human skin through elastic tightening components at the face and neck, effectively reducing gaps for the intrusion of toxic agents. Simultaneously, this invention provides a fully detachable thermal liner, which is conveniently connected to the inside of the protective suit via Velcro, achieving "multi-purpose" functionality: in cold environments, the thermal liner provides effective insulation; in warmer seasons, removing the thermal liner transforms it into a regular protective suit with excellent breathability, meeting the needs of cross-regional, all-season combat or operational needs.

[0015] The beneficial effect of this invention is that it solves the contradiction between windproof and warmth retention and breathability and moisture wicking in traditional protective clothing in cold environments. While ensuring at least 24 hours of durable protective performance, it achieves a high breathability of at least 100mm / s, providing users with all-weather, all-area, safe and comfortable full-body protection.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the various embodiments of the present invention will be described in detail below with reference to the accompanying drawings. However, those skilled in the art will understand that many technical details have been presented in the various embodiments of the present invention to enable the reader to better understand the present invention. However, the technical solutions claimed in the present invention can be implemented even without these technical details and various changes and modifications based on the following embodiments.

[0021] One embodiment of the present invention provides a protective clothing material, including an outer layer and an inner layer; the outer layer is a functional layer for providing flame retardant, water-repellent, oil-repellent and breathable functions; the inner layer is a protective layer for providing protective and breathable functions.

[0022] In one specific embodiment, the outer layer is a fabric that has been treated with flame retardancy, water repellency and oil repellency and has high breathability through optimized weaving parameters; the middle layer includes a protective layer made of carbon fiber material.

[0023] In one specific embodiment, the intermediate layer includes a protective layer made of carbon fiber material and a skeleton layer for supporting the protective layer, the skeleton layer being flame-retardant treated cotton fabric.

[0024] Another aspect of the present invention provides a protective suit, see reference. Figure 1 , Figure 2 It includes a one-piece protective hood 4 and a gas suit body 5, as well as a detachable and connectable thermal inner liner.

[0025] This invention resolves the contradiction between windproof warmth and breathability / moisture wicking in traditional protective suits in cold environments. While ensuring at least 24 hours of continuous protection against toxic substances, it achieves a high breathability of at least 100mm / s, providing users with all-weather, all-terrain, safe, and comfortable full-body protection. Specifically, the outer layer of the protective suit uses highly flame-retardant acrylonitrile cellulose fabric as the base material, and undergoes a systematic oil- and water-repellent treatment, giving the outer layer excellent flame-retardant properties, high tensile strength and tear strength, as well as reliable waterproof and oil-proof capabilities. Simultaneously, during the fabric weaving process, the microstructure of the fabric is optimized by precisely adjusting the warp and weft yarn count ratio, significantly improving the material's breathability and laying a solid foundation for the overall wearing comfort of the protective suit. The middle layer of the protective suit adopts a composite structure, consisting of a protective layer and a support layer. The protective layer is made of polyacrylonitrile carbon fiber material, giving the protective suit the characteristics of being lightweight, breathable, and providing excellent protection. The support layer material is flame-retardant treated cotton fabric, which provides physical support and protection for the brittle carbon fiber protective layer, enhancing the material's durability; on the other hand, the natural comfort of cotton fabric further enhances the wearing experience of the protective suit. The inner layer of the protective suit is made of double-sided fleece. Tests show that its warmth retention per unit weight is twice that of merino wool and four times that of cotton. Furthermore, double-sided fleece has excellent moisture management capabilities, quickly absorbing and drying moisture emitted by the body, effectively preventing the cold feeling caused by sweat buildup. This provides warmth while improving the comfort of the protective suit.

[0026] In one specific embodiment, the protective hood has elastic fastening elements at the facial openings and neck area for a tight fit with the gas mask and the human body.

[0027] Specifically, in this embodiment, the protective hood 4 of the gas suit adopts a three-piece design, which better conforms to the shape of the human head. Elastic tightening elements are provided at the edges of the facial openings and the neck area of ​​the protective hood 4. When the worker wears the gas suit and a gas mask, the elastic tightening elements at the facial openings of the protective hood 4 generate a uniform radial contraction force, tightly wrapping and fitting the protruding parts of the gas mask, such as the lens, communicator, and filter canister connector, ensuring a tight fit between the face of the protective hood 4 and the gas mask. Simultaneously, the elastic tightening elements around the neck adaptively contract, gently and firmly conforming to the contours of the user's neck. This synergistic effect not only effectively blocks the path that toxic gases, bacteria, and radioactive dust may enter through the gaps in the head and neck, ensuring the overall airtightness and reliability of the protective system, but also avoids the pressure caused by excessive reliance on rigid tightening. While ensuring safety, it significantly improves the comfort and flexibility of wearing the gas suit for extended periods.

[0028] In one specific embodiment, reference is made to... Figure 1 The main body of the protective suit 5 is equipped with a waist adjustment structure, a double-layer closed front, and adjustable cuffs and trouser legs.

[0029] Specifically, in this embodiment, the main body 5 of the protective suit adopts a relatively loose fit to ensure that workers can move freely in different seasons and under different clothing conditions. Meanwhile, the shoulder and neck areas follow ergonomic design to ensure smooth movement and a feeling of freedom of movement. A built-in elastic adjustment device is designed at the waist, allowing workers to quickly adjust the waist tightness by pulling the elastic cord. This ensures the protective suit fits different body types snugly, effectively preventing protective failure or movement difficulties due to excessive looseness at the waist, and also preventing pressure caused by excessive tightness. The front of the suit uses a double-layer closure system combining zippers and Velcro: the zipper provides initial closure and quick donning / undressing, while the Velcro covering the zipper provides secondary positioning and sealing. This design not only enhances the overall airtightness of the front area but also significantly improves the reliability of the protective suit in harsh environments. Both the cuffs and trouser legs feature a double-layered composite structure: the inner layer is an elastic band that gently conforms to the wrists and ankles, forming a basic seal to prevent harmful substances from entering; the outer layer is an adjustable flared design with Velcro fasteners, allowing workers to tighten or loosen the cuffs as needed.

[0030] In one specific embodiment, reference is made to... Figure 2 The thermal inner lining includes an upper garment 7 and trousers 8, which are connected to the inside of the main body 5 of the protective suit via Velcro. The cuffs, trouser legs and waist of the upper garment 7 and trousers 8 are equipped with elastic tightening structures.

[0031] In one specific embodiment, the jacket 7 is provided with an anti-slip cuff structure and a smooth zipper opening and closing structure.

[0032] Specifically, in this embodiment, the thermal inner jacket 7 uses a smooth zipper for front opening and closing, ensuring convenient and efficient donning and doffing. Its cuffs and waist both employ an elasticated structure, closely conforming to the curves of the wrists and waist, avoiding bulkiness and ensuring freedom of movement while effectively preventing the intrusion of external cold air and the loss of internal heat, achieving good localized windproof and warming effects. To further enhance stability during movement, anti-slip ropes are specially designed at the cuffs, allowing workers to secure the rope loops to their thumbs, effectively preventing the sleeves from riding up during large movements such as arm extension and raising, maintaining continuous coverage of the warm area. Furthermore, the jacket has pre-installed hook and loop fasteners on both sides of the zipper, which can be securely connected to corresponding positions on the inside of the main body 5 of the protective suit, ensuring that the thermal inner jacket does not shift inside the garment. This allows workers to easily remove and install the thermal inner jacket according to temperature changes to adapt to different working environments. The trousers 8 with the thermal inner liner also feature an elasticated waistband and cuffs, ensuring a snug fit, preventing drafts, and allowing for freedom of movement. A Velcro strap at the cuffs of the trousers 8 connects to the inside of the cuffs of the main body of the protective suit 5. This design further enhances the overall integrity and stability of the thermal inner liner, effectively preventing the trousers 8 from accidentally riding up during various activities and ensuring continuous leg protection and warmth.

[0033] In one specific embodiment, the air permeability of the protective suit is not less than 100 mm / s, and the protection time against toxic agents is not less than 24 hours.

[0034] The protective suit provided by this invention achieves a balance of protection, breathability, and warmth through a three-layer composite structure: an outer layer made of flame-retardant, water-repellent, and oil-repellent breathable fabric; a middle layer of carbon fiber protective material; and an inner layer of moisture-wicking, quick-drying, and warm insulation. Combined with the elastic sealing design of the one-piece protective hood, it ensures a tight fit to the body and gas mask. Furthermore, the modular design of the removable warm inner liner allows the same protective suit to adapt to different seasons and regions. While ensuring at least 24 hours of continuous protective performance, it achieves a high breathability of at least 100mm / s, effectively resolving the contradiction between windproof warmth and breathability in cold environments found in traditional protective suits, providing users with all-weather, all-terrain safe and comfortable protection.
