Description

Technical Field

[0001] This invention relates to the field of fabric technology, specifically to a high-performance loungewear fabric and its preparation method. Background Technology

[0002] Modal fabric, a regenerated cellulose fiber fabric made from lignocellulose through a special process, is widely used in underwear, home textiles, and casual wear due to its excellent moisture absorption, soft touch, and good biocompatibility, and is highly favored by consumers.

[0003] Patent CN109972407A discloses a method for preparing anti-mite modal fabric, belonging to the field of fabric technology. This invention prepares anti-mite modal fabric by attaching calcium carbonate anti-mite microcapsules to modal fabric. The organic anti-mite agent is completely encapsulated in the calcium carbonate microcapsules and then adhered to the modal fabric by the force of an aqueous adhesive. This effectively reduces the loss of organic anti-mite agents during washing, thereby delaying the action time of the organic anti-mite agents and improving the anti-mite effect of the modal fabric. However, under the mechanical action of friction and washing during daily wear, the fiber ends of modal fabric easily slip out of the fabric and form fuzz. Further entanglement of these fuzzes forms lint balls, which not only affects the neatness of the fabric's appearance but also reduces wearing comfort. Summary of the Invention

[0004] The purpose of this invention is to provide a high-performance homewear fabric and its preparation method to solve the problems existing in the prior art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A high-performance loungewear fabric, wherein the high-performance loungewear fabric is obtained by treating modal fabric with a composite finishing agent; the composite finishing agent is obtained by graphene oxide powder, polyvinylpyrrolidone, deionized water, polyoxyethylene sorbitan monooleate, pentaerythritol triacrylate, functionalized silk fibroin, sodium bicarbonate and potassium persulfate; the functionalized silk fibroin is prepared by silk fibroin solution, sodium hydroxide aqueous solution, glycidyl methacrylate, polyoxyethylene sorbitan monooleate, hydrochloric acid aqueous solution and anhydrous ethanol; the silk fibroin solution is prepared by silkworm cocoon, sodium carbonate aqueous solution and lithium bromide aqueous solution.

[0006] Furthermore, the mass ratio of silkworm cocoons, sodium carbonate aqueous solution, and lithium bromide aqueous solution is 1:(40-60):(8-12).

[0007] Furthermore, the mass ratio of silk fibroin solution, glycidyl methacrylate, polyoxyethylene sorbitan monooleate and anhydrous ethanol is 100:(4-6):(1.0-2.5):(400-600).

[0008] Furthermore, the mass ratio of graphene oxide powder, polyvinylpyrrolidone, deionized water, polyoxyethylene dehydrated sorbitan monooleate, pentaerythritol triacrylate, functionalized silk fibroin, sodium bicarbonate and potassium persulfate is 0.5:(6-8):(80-120):(1-2):(1.0-1.2):(2-4):(1-2):(0.1-0.2).

[0009] A method for preparing a high-performance loungewear fabric includes the following steps: (1) Cut the silkworm cocoons into pieces, add them to a sodium carbonate aqueous solution, stir at 200-300 rpm for 50-70 minutes at 95-100℃, filter and rinse with deionized water 3-5 times, then dry at 55-65℃ for 2-4 hours to obtain silk fibroin, then add the silk fibroin to a lithium bromide aqueous solution, stir for 3-4 hours under nitrogen protection, 68-72℃ and 200-300 rpm, then cool to 40-45℃, then transfer to a dialysis bag, dialyze in flowing deionized water for 60-72 hours, then concentrate and evaporate at 40-50℃ using a rotary evaporator to obtain a silk fibroin protein solution with a mass fraction of 6-8%; (2) Take the silk fibroin solution obtained in step (1), adjust the pH to 7.5-8.5 with sodium hydroxide aqueous solution with a mass fraction of 1-2%, and slowly add glycidyl methacrylate and polyoxyethylene dehydrated sorbitan monooleate dropwise over 30-40 minutes under stirring conditions of 45-55℃ and 250-350rpm. Then continue stirring for 8-10 hours. After that, adjust the pH to 7.0-7.5 with hydrochloric acid aqueous solution with a mass fraction of 0.5-1%. Then, under nitrogen protection, 5-10℃ and 200-300rpm, slowly add the reaction solution to anhydrous ethanol over 30-60 minutes for precipitation. After the addition is complete, continue stirring for 2-3 hours. Then, centrifuge at 8000-10000rpm for 15-20 minutes and wash 2-4 times with ethanol aqueous solution with a mass fraction of 70-80% to obtain functionalized silk fibroin. (3) Add graphene oxide powder and polyvinylpyrrolidone to deionized water and ultrasonically disperse at 500-600W for 50-60 minutes. Then add polyoxyethylene dehydrated sorbitan monooleate, pentaerythritol triacrylate, functionalized silk fibroin and sodium bicarbonate. Mix at 300-400rpm for 2-3 hours. Then add potassium persulfate and continue stirring for 30-40 minutes to obtain the composite finishing agent. (4) The modal fabric is then immersed in the composite finishing agent obtained in step (3) at 25±5℃. The two-dip and two-padding process is adopted. The immersed and padded fabric is first dried with hot air at 100-105℃ for 2-3 minutes, then baked at 145-155℃ for 3-4 minutes, and finally washed with warm water at 35-45℃ for 10-20 minutes and dried at 80-90℃ for 5-10 minutes to obtain high-performance home wear fabric.

[0010] Furthermore, the mass fraction of the sodium carbonate aqueous solution in step (1) is 0.4-0.6%.

[0011] Furthermore, in step (1), the molecular weight cutoff of the dialysis bag is 3500 Da.

[0012] Furthermore, the mass fraction of the lithium bromide aqueous solution in step (1) is 55-60%.

[0013] Furthermore, in step (3), the sheet size of the graphene oxide powder is 5-20 μm and the thickness is 0.8-1.2 nm.

[0014] Furthermore, in step (4), the bath ratio is 1:30-50, each immersion lasts 2-3 minutes, the rolling rate is 75-80%, and the rolling pressure is 2-4 MPa.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: In this invention, silkworm cocoons are treated with sodium carbonate aqueous solution to remove sericin, and then silk fibroin is dissolved in lithium bromide aqueous solution to obtain a silk fibroin aqueous solution. Subsequently, the epoxy groups in glycidyl methacrylate molecules undergo a ring-opening addition reaction with the hydroxyl and amino groups on the silk fibroin molecular chain, thereby covalently grafting the carbon-carbon double bonds at the end of the glycidyl methacrylate molecules onto the silk fibroin molecules to obtain functionalized silk fibroin. The carboxyl, hydroxyl, and epoxy groups on the graphene oxide sheets can form hydrogen bonds with the amino and hydroxyl groups on the surface of the silk fibroin. Potassium persulfate decomposes upon heating to generate sulfate free radicals, which can initiate the free radical polymerization reaction of pentaerythritol triacrylate and the carbon-carbon double bonds on the surface of the functionalized silk fibroin to form a silk fibroin polymer network, forming a composite functional layer. The graphene oxide sheets in this composite functional layer are bonded to the silk fibroin molecules. The synergistic effect of the silk fibroin polymer network increases the binding force between Modal fabric fibers, inhibiting the slippage of fiber ends during friction and thus improving the fabric's anti-pilling properties. The hydrophilicity of silk fibroin and the pores generated by the thermal decomposition of sodium bicarbonate provide adsorption and transport pathways for water molecules. Polyvinylpyrrolidone, as a dispersant and water-soluble pore-forming agent, leaves a porous structure after washing to remove polyvinylpyrrolidone. These porous structures, together with the aforementioned pores, constitute moisture transport pathways, improving the fabric's breathability and moisture permeability. In addition, graphene oxide forms a physical barrier on the fiber surface, reducing direct friction between fibers, while the cross-linked network reduces fiber end slippage, thus providing good anti-pilling properties. The coating and binding effect of graphene oxide sheets and silk fibroin polymer network on Modal fabric fibers, as well as the elasticity of the composite functional layer itself, jointly enhance the fabric's wrinkle resistance.

The carbon-carbon double bonds carried on the surface of pentaerythritol triacrylate and functionalized silk fibroin can undergo free radical polymerization under the initiation of free radicals generated by the thermal decomposition of potassium persulfate, forming a composite functional layer. The graphene oxide sheets in this composite functional layer synergistically work with the silk fibroin polymer network to increase the bonding force between modal fabric fibers, thereby inhibiting the slippage of fiber ends during friction and improving the fabric's anti-pilling properties. The hydrophilicity of silk fibroin and the use of sodium bicarbonate... The pores created by thermal decomposition provide pathways for water molecule adsorption and transport. Polyvinylpyrrolidone, as a dispersant and water-soluble pore-forming agent, leaves a porous structure after washing to remove the polyvinylpyrrolidone. These porous structures, together with the aforementioned pores, constitute moisture transport pathways, improving the fabric's breathability and moisture permeability. In addition, graphene oxide forms a physical barrier on the fiber surface, reducing direct friction between fibers. At the same time, the cross-linked network reduces fiber end slippage, thus providing good anti-pilling properties. The coating and binding effect of graphene oxide sheets and silk fibroin polymer network on modal fabric fibers, as well as the elasticity of the composite functional layer itself, jointly enhance the fabric's wrinkle resistance.
