Description

Technical Field

[0001] This invention relates to the field of protective clothing technology, specifically to a highly breathable, antibacterial, lightweight protective suit and protective clothing material. Background Technology

[0002] The main body of existing medical protective clothing is mostly made of a single layer of ordinary non-woven fabric or chemical fiber non-woven fabric. This type of protective clothing does not have water absorption or sweat absorption properties, and has poor breathability and moisture permeability, making it easy for bacteria and viruses to invade. Since medical personnel may be exposed to toxic and harmful gases, aerosols, harmful blood or body fluids, as well as some harmful or infectious viruses and microorganisms, existing medical protective clothing cannot meet the needs of medical personnel. Prolonged use of such protective clothing will not only increase the risk of bacterial infection for medical personnel, but also increase the probability of heatstroke for medical personnel working in high-temperature environments due to the poor breathability of the protective clothing.

[0031] Figure 2 This is a schematic diagram of the structure of the present invention.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example:

[0035] like Figure 1-2 As shown, this embodiment of the invention provides a highly breathable, antibacterial, lightweight protective suit and protective suit material, including an upper protective suit 1, a lower protective suit 3, and a head protective suit 4. The upper protective suit 1, lower protective suit 3, and head protective suit 4 are all integrally formed. A zipper 2 is provided in the middle of the front side of the upper protective suit 1. Protective gloves 5 are provided at the bottom of the sleeves on both sides of the upper protective suit 1. Wrist elastic bands 11 are provided on the outer periphery between the upper protective suit 1 and the protective gloves 5. Ankle elastic bands 12 are provided on the outer periphery of the bottom of the trouser legs on both sides of the lower protective suit 3. By providing wrist elastic bands 11 and ankle elastic bands 12 respectively, the wrists and ankles of the protective suit can fit the wearer's skin, making it more convenient and efficient for the wearer to move when wearing this protective suit.

[0036] The upper protective suit 2, lower protective suit 3 and head protective suit are all made of the same material and are composed of a breathable layer 6, a fireproof layer 7, an activated carbon adsorption layer 8, an antibacterial layer 9 and a dehumidifying layer 10.

[0037] By modifying the materials used in the manufacture of traditional protective suits, a new material is employed. This new material combines a breathable layer (6) to enhance breathability, a fire-resistant layer (7) to prevent the spread of fire, an activated carbon adsorption layer (8) to preliminarily adsorb toxic and harmful gases, an antibacterial layer (9) to prevent bacterial growth, and a desiccant layer (10) with extremely high water absorption capacity. This significantly improves not only the breathability and antibacterial properties of the protective suit but also its desiccant and fire-resistant properties, thereby greatly enhancing the comfort and safety of wearing the protective suit.

[0038] Combination Figure 2 To illustrate, the breathable layer 6 is bonded to the fireproof layer 7, the activated carbon adsorption layer 8 is bonded to the fireproof layer 7, the other side of the activated carbon adsorption layer 8 is bonded to the antibacterial layer 9, and the antibacterial layer 9 is bonded to the dehumidification layer 10.

[0039] Breathable layer 6 is woven from polyester fibers, with a warp density of 50-60 threads / cm. 2 The latitude is 60-65 threads / cm 2 This weaving method makes the fabric stronger.

[0040] This weaving method increases the gaps in the outermost layer of fabric of the protective suit, thereby improving its breathability.

[0041] The preparation of fireproof layer 7 includes the following steps:

[0042] Step 1: Weave the pre-treated yarn to make primary fabric;

[0043] Step 2: Soak the primary fabric in a 3% ammonium polyphosphate solution for 2-3 hours;

[0044] Step 3: After taking the fabric out, let it air dry for 5-6 hours. Then, apply a layer of polyurethane foam adhesive with a thickness of 0.2-0.5mm to both sides of the fabric.

[0045] Ammonium polyphosphate is a high-performance non-halogenated flame retardant. Soaking primary fabrics in ammonium polyphosphate solution can improve the fire resistance of the fabric. Polyurethane foam, also known as polyurethane resin, is an excellent waterproof and heat-insulating material. Applying this material to the soaked fabric can further improve the fire resistance of protective clothing.

[0046] The activated carbon adsorption layer 8 is specifically an activated carbon filter cotton, and the preparation of the activated carbon filter cotton includes the following steps:

[0047] Step 1: Select polyurethane foam and lay a layer of activated carbon particles with a diameter of 0.5-0.8mm inside it;

[0048] Step 2: Apply a protective film to the surface of the polyurethane foam to prevent the internal activated carbon particles from falling off.

[0049] The activated carbon particles inside the activated carbon filter cotton are sealed by a protective film. These activated carbon particles can adsorb toxic and harmful gases that pass through the protective clothing, thus preventing harm to the health of the user.

[0050] The preparation of antibacterial layer 9 includes the following steps:

[0051] Step 1: Immerse the base fabric made of polyurethane fibers in the antibacterial solution for 2-3 hours;

[0052] Step 2: After soaking, take the fabric out and dry it to set its shape;

[0053] Step 3: Spray the dried fabric surface with an antibacterial liquid made of isopropanol, cresol and phthalimide in a ratio of 1:2:1, and let it air dry for 3 hours to obtain the antibacterial layer 9.

[0054] Immersing the base fabric made of polyurethane fiber in an antibacterial solution gives the antibacterial layer 9 its initial antibacterial ability. Isopropanol, cresol, and phthalimide are all chemically synthesized antibacterial agents. Mixing them in a fixed ratio can significantly enhance the antibacterial ability of the mixture. Spraying the mixture onto the surface of the antibacterial layer 9 further enhances its antibacterial ability. This can block most medical personnel from being exposed to toxic and harmful gases, sols, harmful blood or body fluids, as well as some harmful or infectious viruses and microorganisms, thus improving the protective performance of the protective clothing.

[0055] The preparation of the dehumidification layer 10 includes the following steps:

[0056] Step 1: Prepare a 15% calcium chloride solution and soak the polyester fabric in the calcium chloride solution for 1-2 hours;

[0057] Step 2: Place the soaked fabric inside a drying oven and dry at 100℃ for 3-4 hours to allow the fabric to mix with the calcium chloride solution.

[0058] Calcium chloride is a colorless cubic crystal, white or grayish-white, available in granular, honeycomb-like, spherical, irregular granular, and powder forms. It is slightly toxic, odorless, and has a slightly bitter taste. It possesses extremely strong hygroscopic properties. A solution prepared with calcium chloride is applied to the interior of the dehumidifying layer 10 fabric. After drying, most of the moisture in the solution is removed, leaving the calcium chloride powder inside the dehumidifying layer. Utilizing the strong hygroscopic properties of calcium chloride, it absorbs sweat produced by the body inside the protective suit, maintaining a dry environment inside the suit at all times and greatly improving the comfort of the protective clothing.

[0059] The prepared dehumidification layer 10, antibacterial layer 9, activated carbon adsorption layer 8, fireproof layer 7 and breathable layer 6 are laid from bottom to top and bonded together with water-based composite adhesive.

[0060] Although this protective suit uses a multi-layer adhesive structure, the weaving method used for the breathable layer in the fabric fabrication takes into account breathability. Therefore, the present invention lays the dehumidifying layer 10, antibacterial layer 9, activated carbon adsorption layer 8, fireproof layer 7 and breathable layer 6 in sequence from bottom to top, but the breathability will not be affected.

[0061] Multiple layers of fabric are combined into one material, which is used to make protective clothing.

[0062] In the preparation of antibacterial layer 9, when drying the fabric in step two, the drying temperature is 120-150℃ and the drying time is 5-6 hours.

[0063] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
