Description

Technical Field

[0001] The present invention belongs to the technical field of composite fabric processing, and particularly relates to an antibacterial, odor-removing and non-ironing treatment method for shirts. Background Art

[0002] A composite fabric is a new type of material formed by bonding and laminating one or more layers of textile materials, non-woven materials and other functional materials. A non-ironing finishing agent is a liquid finishing agent coated on the fabric, which can change the surface properties of the fabric, making it less or free from ironing, etc. Adding some nanomaterials during the clothing manufacturing process, such as: nano silver powder, nano zinc oxide powder, nano copper oxide powder, nano titanium dioxide powder, etc., can achieve additional functions such as antibacterial, bactericidal, mildew-proof, deodorant, odor-removing, self-cleaning of the product.

[0003] At present, shirts are prone to breed bacteria after being worn for a long time, resulting in bad odors (such as body odor, axillary osmidrosis), etc. After being worn and then washed, the shirts will be stored. After being stored for a long time, the shirts are prone to breed bacteria, resulting in peculiar smells, etc. In special occasions such as hospitals, the shirts worn by doctors need to have functions such as antibacterial and odor-removing to better protect themselves and patients.

[0004] Therefore, how to process shirts so that they can achieve non-ironing, antibacterial and odor-removing functions, and improve the practicality, comfort and aesthetics of shirts is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Invention

[0005] The purpose of the present invention is to provide an antibacterial, odor-removing and non-ironing treatment method for shirts.

[0006] In order to achieve the above purpose, the technical solution of the present invention is as follows:

[0007] An antibacterial, odor-removing and non-ironing treatment method for shirts, comprising the following steps carried out in sequence:

[0008] 1) Prepare polyester fiber: The polyester fiber is prepared by first heating and melting and then extruding;

[0009] Then, at the extrusion outlet of the polyester fiber, a gas material mixture of nano antibacterial powder and compressed nitrogen is sprayed onto the outer surface of the molten polyester fiber. The nano antibacterial particles are driven by the compressed nitrogen into the outer surface of the molten polyester fiber so that a part of the volume of the nano antibacterial particles is buried in the molten polyester fiber. The polyester fiber is air-cooled by the compressed nitrogen and then solidified. After spraying and air-cooling simultaneously, the nano antibacterial particles are buried on the outer surface of the solidified polyester fiber;

[0010] 2) Blend the polyester fiber obtained in step 1) with cotton fiber to obtain a blended yarn;

[0011] Then, the blended yarn is woven to obtain a fabric;

[0012] Then, the fabric is made into a shirt;

[0013] 3) Dip coating: The shirt is immersed in a non-iron finishing agent containing nano-antibacterial powder for dip coating, so that the nano-antibacterial particles are adhesively fixed on the polyester fibers and cotton fibers in the shirt through the dip-coated non-iron finishing agent;

[0014] 4) First pre-drying: The dip-coated shirt is heated and pre-dried once;

[0015] 5) Spraying: A non-iron finishing agent containing nano-antibacterial powder is atomized and sprayed evenly on the outer and inner surfaces of the shirt, so that the nano-antibacterial particles are adhesively fixed on the polyester fibers and cotton fibers in the shirt through the sprayed non-iron finishing agent;

[0016] 6) Second pre-drying: The sprayed shirt is heated and pre-dried a second time;

[0017] 7) Pressing: Each part of the second pre-dried shirt is pressed;

[0018] 8) Baking: The pressed shirt is subjected to a baking treatment;

[0019] 9) Freezing: The baked shirt is transferred to a freezer for freezing treatment;

[0020] 10) Washing with water and then drying, and after completion, an antibacterial and odor-removing non-iron shirt is obtained.

[0021] Preferably, the nano-antibacterial powder includes at least one of nano-silver powder, nano-zinc oxide powder, nano-copper oxide powder, and nano-titanium dioxide powder.

[0022] Preferably, in step 1), the addition amount of the nano-antibacterial powder is: after cooling and solidifying, it is controlled to weigh 0.02 kg - 0.15 kg of nano-antibacterial powder per 1 kg increase in the weight of polyester fiber.

[0023] Preferably, the mass of the polyester fiber: the mass of the cotton fiber = (5 - 20):(80 - 95).

[0024] Preferably, the content of the nano-antibacterial powder in the non-iron finishing agent is 30 - 70 g / L, and the particle size of the nano-antibacterial powder is 10 nm - 300 nm.

[0025] The present application has achieved the following beneficial technical effects:

[0026] In this application, the no-iron treatment of ready-to-wear shirts is achieved by successively dip-coating with a no-iron finishing agent, pre-drying once, spraying the no-iron finishing agent, pre-drying twice, pressing, baking, freezing, washing, and drying, which improves the practicality, comfort, and aesthetics of the shirts.

[0027] In this application, in the current prior art, nano-titanium dioxide powder is added to the finishing agent to make an antibacterial and mildew-proof finishing agent, and then the antibacterial and mildew-proof finishing agent is sprayed on the shirt to achieve the effects of antibacterial, bactericidal, mildew-proof, deodorizing, removing peculiar smells, and self-cleaning of the shirt. However, since the main component of the antibacterial and mildew-proof finishing agent is usually resin, which is an artificially synthesized organic liquid, while the cotton fiber in the cotton shirt is a natural fiber, the resin in the finishing agent and the cotton fiber are two materials with quite different properties. Naturally, there is an interfacial effect between the two. As a result, although the nano-titanium dioxide powder is bonded and fixed on the cotton fiber by the resin in the finishing agent, due to the above-mentioned interfacial effect, the adhesion force is small, and the titanium dioxide powder is easy to fall off and powder, and the more powder falls off over time, resulting in the easy failure of functions such as antibacterial and deodorizing.

[0028] Therefore, in this application, first, through blending, polyester fiber, an artificially synthesized organic substance, is added to the cotton fiber, and then a no-iron finishing agent containing nano-antibacterial powder is dip-coated and sprayed on the shirt. Here, the no-iron finishing agent has the function of an adhesive, and the nano-antibacterial particles in the no-iron finishing agent will be bonded and fixed on the cotton fiber in the shirt through the no-iron finishing agent, and will also be bonded and fixed on the polyester fiber in the shirt.

[0029] Since polyester fiber is essentially resin, and the main component in the no-iron finishing agent is also resin, and since both are resins and belong to the same category of substances, there is no interfacial effect between the polyester fiber and the no-iron finishing agent. Furthermore, the connection force and connection strength between the polyester fiber and the no-iron finishing agent are greater, making the nano-antibacterial particles more firmly bonded and fixed on the polyester fiber by the no-iron finishing agent, making the connection force and connection strength between the nano-antibacterial particles and the polyester fiber greater, and the nano-antibacterial particles on the polyester fiber are less likely to fall off and powder.

[0030] Furthermore, due to the greater connection force and connection strength between the polyester fiber and the non-iron finishing agent, the polyester fiber can serve as the strong center and foundation among the four components: polyester fiber, cotton fiber, non-iron finishing agent, and nano-antibacterial particles. The polyester fiber as the center can directly or indirectly drag and pull other cotton fibers, non-iron finishing agents, and nano-antibacterial particles. The polyester fiber as the center can enhance the bonding strength and overall integrity of the entire system composed of the four components: polyester fiber, cotton fiber, non-iron finishing agent, and nano-antibacterial particles. As a result, the nano-antibacterial particles are more firmly bonded and fixed on the polyester fiber by the non-iron finishing agent and are also more firmly bonded and fixed on the cotton fiber. The nano-antibacterial particles on the polyester fiber and the cotton fiber are less likely to fall off and shed powder.

[0031] In summary, the blended polyester fiber enables the functions such as antibacterial and odor removal of the shirt to be maintained for a longer time as the usage time extends, and it is less likely to experience powder shedding and function failure.

[0032] Second, a large number of nano-antibacterial particles are spray-embedded on the outer surface of the polyester fiber. Since the polyester fiber is in a high-temperature molten state and has not started to cool and solidify at this time, a part of the volume of the nano-antibacterial particles is injected, buried, and embedded in the molten polyester fiber under high pressure and high speed. After the polyester fiber cools and solidifies, the nano-antibacterial particles are firmly fixed in the polyester fiber and then firmly fixed in the shirt. Here, the embedding force and embedding strength between the nano-antibacterial particles and the polyester fiber are much greater than the adhesive force and adhesive strength between the nano-antibacterial particles and the polyester fiber in the above-mentioned dip coating and spraying. Embedding is definitely more secure than adhesion. Therefore, the nano-antibacterial particles embedded here are more firmly fixed in the polyester fiber than the nano-antibacterial particles in the above-mentioned dip coating and spraying, and are less likely to fall off and shed powder. Just like manufacturing a reinforced concrete structure, steel bars are pre-embedded in wet cement concrete first. After the cement concrete solidifies and hardens, the concrete and the steel bars are connected together to form an integral structure such as a reinforced concrete wall or a reinforced concrete column. The pre-embedded connection is very firm and difficult to separate.

[0033] Furthermore, the remaining volume of the nano-antibacterial particles is exposed to the external atmospheric environment. This part of the volume exposed to the external atmospheric environment can directly contact bacteria, viruses, molds, odors, and other odors. It is a direct contact rather than the traditional indirect contact through other things. The direct contact enables the nano-antibacterial particles and their chemical reaction products to carry out sterilization, virus killing, odor removal, etc. more efficiently.

[0034] In summary, spraying and embedding a large number of nano-antibacterial particles on the outer surface of the polyester fiber improves the embedding strength and firmness, makes it less likely to fall off and shed powder, and improves the antibacterial and odor removal ability and efficiency of the shirt, as well as the practicality, comfort, and aesthetics of the shirt.
