Description

Technical Field

[0001] The present invention relates to the technical field of fibers, and particularly to a method for manufacturing a regenerated cotton-like three-proof fiber and a shoe upper. Background Art

[0002] Compared with cotton fabrics, polyester fabrics have poor moisture absorption, moisture retention, and air permeability. They are easy to stick to the body when worn, causing a stuffy feeling. At the same time, they are prone to generating static electricity and attracting dust, affecting beauty and comfort. Cotton fibers, on the other hand, have poor wear resistance and poor stain resistance. Both have drawbacks and cannot meet user needs.

[0003] To solve this problem, the present invention is thus produced. Summary of the Invention

[0004] Therefore, in view of the above problems, the present invention provides a method for manufacturing a regenerated cotton-like three-proof fiber and a shoe upper, which has the properties of softness, moisture absorption, waterproofness, stain resistance, and wear resistance.

[0005] To solve the above technical problems, the solution adopted by the present invention is as follows: A method for manufacturing a regenerated cotton-like three-proof fiber includes the following steps: Step 1: Perform a fluffing process on the PET material to make the material have the soft properties of cotton fibers; Step 2: Put the treated PET material into a machine for spinning to obtain cotton-like polyester fiber yarn; Step 3: Perform a degreasing process on the surface of the cotton-like polyester fiber yarn; Step 4: Perform a waterproof process on the degreased cotton-like polyester fiber yarn to make the fiber have a waterproof effect; Step 5: Dehydrate the cotton-like polyester fiber yarn, then dry it in an oven at 110°C for 3 hours, and cool and solidify it; Step 6: Wind the cotton-like polyester fiber yarn onto a bobbin to complete the encapsulation.

[0006] Further improvement: It further includes a fiber dyeing process, which is located between Step 3 and Step 4 for dyeing the cotton-like polyester fiber yarn.

[0007] Further improvement: The fluffing process is as follows: Chemical foaming is used, and a foaming agent is added to the PET to make it foam and fluff.

[0008] Further improvement: The degreasing process is as follows: A polyurethane coating or a silane coupling agent is sprayed or impregnated to form a protective film to prevent the migration of grease inside the cotton-proof fiber yarn.

[0009] Further improvement: The waterproof process is as follows: The cotton-like polyester fiber yarn is impregnated in liquid wax to form a waterproof film layer on its surface.

[0010] A further improvement is that it also includes a two-for-one twisting process, which is located between step two and step three and is used to enhance the strength of the cotton-like polyester fiber line.

[0011] A further improvement is that the PET material is polyester material.

[0012] A shoe upper is made of regenerated cotton-like three-proof fiber, and the regenerated cotton-like three-proof fiber is made by the above-mentioned method for making regenerated cotton-like three-proof fiber.

[0013] By adopting the above technical solution, the beneficial effects of the present invention are: 1. Before spinning, the PET material is fluffed, which makes the cotton-like polyester fiber thread more comfortable than polyester. The fabric woven from this cotton-like polyester fiber thread is not only soft and breathable, but also has good moisture absorption. And after being fluffy, it is warm. At the same time, the nature of PET material makes it not easy to deform and does not run, which is conducive to long-term use by users.

[0014] 2. Then, through degreasing, the oiliness on the fiber surface can be removed, so that it will be more comfortable when in contact with the skin and will not feel greasy.

[0015] 3. Fluorine-free waterproof treatment makes the fiber surface waterproof, so that the fabric can be better worn on wet and rainy days and is not easily wetted.

[0016] 4. The anti-fiber is made of PET material, which makes it have the properties of polyester. It is not only wear-resistant but also stain-resistant. At the same time, it has good toughness and is not easy to break, which is conducive to users wearing it for a long time. It is also washable and can dry faster. DETAILED DESCRIPTION

[0017] The present invention will now be further described with reference to specific embodiments.

[0018] The embodiment of the present invention discloses: a method for making a regenerated cotton-like three-proof fiber, comprising the steps of: performing a fluffing process on a polyester material, chemically foaming the polyester material, adding a foaming agent to the polyester material to make it foamed and fluffy, so that the material has the softness of cotton fiber; Step 2: putting the treated polyester material into a machine for spinning to obtain cotton-like polyester fiber yarn; Step 3: Degreasing the surface of the imitation cotton polyester fiber line can be done by spraying or dipping a layer of fluorine-free polyurethane coating or silane coupling agent to form a protective film to prevent the migration of grease inside the anti-cotton fiber line; Step 4: Immerse the degreased cotton-like polyester fiber yarn in liquid wax for waterproof treatment, so that a waterproof film layer covers its surface, endowing the fiber with waterproof effect. Step 5: Dehydrate the cotton-like polyester fiber yarn, then dry it in an oven at 110 °C for 3 hours, and cool and solidify it. Step 6: Wind the cotton-like polyester fiber yarn onto a bobbin to complete the encapsulation.

[0019] In order to obtain cotton-like polyester fiber yarn in more colors and thus meet the needs of different users, a fiber dyeing process is also included. The fiber dyeing process is located between Step 3 and Step 4 and is used to dye the cotton-like polyester fiber yarn. After the cotton-like polyester fiber yarn is degreased, it can be dyed to match the needs of different customers, and then waterproof treatment is carried out.

[0020] In order to improve the strength of the cotton-proof fiber, a doubling and twisting process is also included. The doubling and twisting process is located between Step 2 and Step 3 and is used to enhance the strength of the cotton-like polyester fiber yarn.

[0021] Among them, before the cotton-like polyester fiber yarn is drawn, the PET material is fluffed, which makes the drawn cotton-like polyester fiber yarn have softer properties, better breathability and better hygroscopicity compared with polyester. At the same time, through degreasing, the oiliness on the fiber surface can be removed, so that it is more comfortable to contact with the skin and does not feel greasy. At the same time, after waterproof treatment, the fiber surface has a waterproof function, so that the fabric can be worn better in humid days and rainy days and is not easily wetted. And the cotton-proof fiber is made of PET material, endowing it with the properties of polyester, not only wear-resistant but also stain-resistant. At the same time, it also has good toughness and is not easy to break, which is beneficial for users to wear for a long time. In terms of washing, it is also wash-resistant and can dry more quickly. It realizes that the fiber can be soft, breathable, hygroscopic, and has three-proof functions of waterproof, anti-fouling and anti-wear.

[0022] A shoe upper is woven from the regenerated cotton-like three-proof fiber produced in the above steps.
