Description

Technical Field

[0001] The invention relates to the technical field of fabrics, and in particular to a method for preparing an anti-pilling and wear-resistant double-layer laminated fabric. Background Art

[0002] Traditional fabrics are usually made of natural fibers such as cotton, linen, and silk. Natural fibers usually have the advantages of being hygroscopic, breathable, and harmless to the body, but they are prone to wrinkling, deformation, and wear. Artificial fibers are chemical fibers made from polymers through chemical treatment and mechanical processing. Artificial fibers have more functionality and higher wear resistance, but they are not as skin-friendly and environmentally friendly as traditional natural fibers.

[0003] On this basis, the advantages of the two major types of fibers are combined to prepare a double-sided laminated fabric. Due to the excellent physical and chemical properties of graphene oxide, it has great development value in the field of fabrics. However, due to its lamellar structure, graphene oxide is very easy to agglomerate, so larger particle size particles will appear when preparing fibers. The large graphene oxide particles in the fibers will form stress concentration points, which are easy to break when stretched, reducing the product quality. How to support the layered structure of graphene oxide while taking into account the wear-resistant and anti-pilling effects is the research direction of the present invention. At the same time, minimizing the treatment of the inner layer of natural fibers by chemicals and preventing the residual chemical factors on the fabric from bringing certain negative effects are also the focus of the present invention. In view of the above problems, the present invention provides a method for preparing an anti-pilling and wear-resistant double-layer laminated fabric to solve the current problem. Summary of the invention

[0004] The purpose of the present invention is to provide a method for preparing an anti-pilling and wear-resistant double-layer laminated fabric to solve the problems existing in the prior art.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an anti-pilling and wear-resistant double-layer laminated fabric, wherein the double-layer laminated fabric has a graphene oxide fiber fabric as an outer layer and a pure cotton fiber fabric as an inner layer;

[0006] The anti-pilling and wear-resistant double-layer laminated fabric is prepared by the following method:

[0007] (1) Weigh 3-5 parts of graphene oxide and add them to 50 parts of ethylene glycol, stir them magnetically at 200-600 r / min for 10-30 min at 25° C., ultrasonicate them at 3000 Hz for 30-60 min, then add 0.5-1.5 parts of sodium dodecylbenzene sulfonate, 0.3-1.5 parts of ferric chloride pentahydrate and 1.5-7.5 parts of sodium oxalate, continue to stir until a uniform suspension is formed, then continue to add 0.6-1 parts of tannic acid, continue to stir for 12-24 h, wash the collected precipitate with ethanol and deionized water alternately 3 times after centrifugation, add deionized water and ultrasonicate them at 3000 Hz for 30-60 min to obtain a composite solution;

[0008] (2) The composite solution and KCl-methanol solution are used as the inner layer solution and the receiving solution; the inner layer diameter of the coaxial needle is 500 μm, the thickness is 200 μm, and the outer layer diameter is 1000 μm; the inner layer of the coaxial needle is connected to the injection pump, and the outer layer is connected to the barometer; the injection pump is turned on, and the outer layer solution is injected into the receiving solution to obtain fibers, which are naturally dried at 25° C. for 24 hours to obtain graphene oxide fibers, which are then twisted and woven to obtain a 200 g / m 2 Outer fabric;

[0009] (3) The cotton fibers are subjected to a humidity conditioning treatment at 30° C. and 90% humidity for 24 hours, and then the wet cotton fibers are subjected to a plasma treatment at a power of 1.0-4.0 kW for 15-45 seconds, and then dried at 25° C. for 6 hours. A quaternary ammonium salt surfactant aqueous solution with a concentration of 2 wt% is used as a finishing liquid for immersion and rolling. The finished cotton fibers are subjected to a microwave treatment at a power of 200-600 W for 1-3 minutes, and then twisted and woven to obtain a 300 g / m 2 The inner layer fabric is connected with the outer layer by adhesive to form a double-layer laminated fabric.

[0010] Furthermore, the centrifugation condition in step (1) is 5000 r / min for 30-60 min.

[0011] Furthermore, in step (1), the volume ratio of the precipitate to the deionized water is 1:20.

[0012] Furthermore, the mass concentration of the KCl-methanol solution in step (2) is 3 mol / L.

[0013] Furthermore, in step (2), the flow rate of the inner layer solution is controlled to be 0.6 mL / min.

[0014] Furthermore, in step (2), the flow rate of the outer layer solution is controlled to be 0.1 mL / s by a barometer.

[0015] Furthermore, in step (2), the diameter of the graphene oxide fiber is 500-700 μm.

[0016] Furthermore, in step (3), the quaternary ammonium salt surfactant is N-dimethyl-N-12-alkylaminopropyltrimethoxysilane.

[0017] Furthermore, in step (3), the one-immersion-one-rolling method is to immerse at room temperature for 1 hour, drain and then spin dry until the rolling rate is 50%.

[0018] Furthermore, the adhesive in step (3) is epoxy AB glue.

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] The present invention uses graphene oxide fiber as an outer layer and pure cotton fiber as an inner layer to form a double-layer laminated fabric to achieve the effects of antibacterial, moisture absorption, wear resistance and anti-pilling.

[0021] Firstly, the outer layer is woven with graphene oxide fibers; as the outer layer of the fabric, the main goal is to resist pilling and wear resistance; after the graphene oxide is compounded with the magnetic ferroferric oxide nano-microspheres, tannic acid is added as a modifier, and the large number of phenolic hydroxyl groups at the end of the tannic acid provide binding sites for the graphene oxide and the ferroferric oxide microspheres. The three are complexed and agglomerated, not only coated on the layered structure of the graphene oxide, but also interspersed in the middle of the layered structure, playing a supporting role while making the iron oxide microspheres firmly bonded to the surface of the graphene oxide fibers to form protrusions, thereby achieving the purpose of wear resistance, and the protruding structure also increases a certain friction resistance, and works synergistically with the magnetic effect of iron oxide, so that the fabric can only pill under a larger friction force, thereby achieving a high-efficiency anti-pilling effect.

[0022] Secondly, the inner layer is woven with pure cotton fibers; as the inner layer of the fabric, considering the contact with the human skin surface, the fiber layer is mainly skin-friendly, moisture-absorbing and antibacterial, so soft and skin-friendly pure cotton fibers are used as the main raw materials, firstly through plasma treatment, the energy size is controlled to bombard the surface of the pure cotton fibers with ion beams to form depressions but without destroying the fiber structure; then the inner layer of pure cotton fibers are treated with quaternary ammonium salt surfactants, and the quaternary ammonium salts as cations are electrostatically bonded to the negatively charged cotton fibers in the depressions and are not easy to fall off; finally, microwave treatment is used, and polar molecules such as water and cellulose in the cotton fibers strongly absorb microwaves, generating a large amount of heat, causing some hydrogen bonds and molecular main chains to break, and generating pressure to cause cracks in the cotton fibers, which open channels for the absorption of water molecules inside the fibers, and the broken hydrogen bonds can produce more hydrophilic groups to improve the moisture absorption effect, while the quaternary ammonium salts are not affected and are still grafted on the fiber surface to play an antibacterial effect.
