Description

Technical Field

[0001] The present invention relates to the technical field of knitting fabric production, and specifically to a production process of a health-care scented knitting fabric. Background Art

[0002] Traditional scented textiles mostly adopt spraying processes, where the fragrance is prone to volatilization and not wash-resistant (less than 5 times); the health-care effect is single and mostly relies on single materials such as antibacterial bamboo fibers, lacking composite function design; the addition of functional auxiliaries, especially in spraying processes, affects the air permeability and softness of the fabric; it is difficult to present both long-lasting health-care functions and slow-release fragrance integrally.

[0003] Meanwhile, for traditional scented fabrics, sachets are buried in the middle of the composite fabric layer or microcapsules are used to encapsulate essence, without solving how to load health-care components. Adding natural fibers with health-care effects through blended spinning results in a 20%-30% decrease in fiber strength. The multi-layer composite scented fabric is relatively thick and has a narrow range of use.

[0004] Based on this, the present invention provides a production process of a health-care scented knitting fabric to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a production process of a health-care scented knitting fabric, thereby solving the problems raised in the background art.

[0006] To achieve the above purpose, the present invention provides the following technical solutions:

[0007] The present invention provides a production process of a health-care scented knitting fabric, including the following steps:

[0008] S1. Prepare porous microcapsules;

[0009] S2. Pretreat the base fabric layer;

[0010] S3. Conduct the first shaping and enhance antibacterial properties;

[0011] S4. Penetrate and mix adhesive chemicals;

[0012] S5. Conduct scented layer impregnation and secondary shaping;

[0013] S6. Cure the microcapsules through low-temperature airtight curing;

[0014] S7. Implement the silicone - mugwort powder dotting process;

[0015] S8. Conduct pH value regulation and post-treatment;

[0016] S9. Cure the finished product at 40°C for 30 minutes, and conduct air permeability testing, antibacterial rate detection, and fragrance persistence verification.

[0017] Preferably, the implementation steps of step S1 are as follows: Porous microcapsules are synthesized by the sol-gel method, rose essential oil and nano-silver ion antibacterial agent are respectively loaded into the microcapsules, the curing time is 2 hours, and through the slow-release structure of the microcapsules, the persistence of the fragrance and antibacterial components is prolonged, avoiding rapid volatilization caused by direct exposure.

[0018] Preferably, the implementation steps of step S2 are as follows: Select cotton fiber or polyester fiber base cloth. After fixing the color in the high-temperature dyeing stage, add the nano-silver ion antibacterial agent loaded in the microcapsules to the dyeing vat, and treat it at a high temperature of 110°C for 180 seconds to preliminarily fix the antibacterial agent on the fiber surface and improve the long-term antibacterial performance of the base cloth layer.

[0019] Preferably, the implementation steps of step S3 are as follows: Immerse the base cloth in the treatment liquid containing nano-silver microcapsule additives for 20 seconds, with a liquor ratio of 75-80%, and then enter the stenter. The cotton fiber base cloth is treated at 130°C for 120 seconds, and the polyester fiber base cloth is treated at 110°C for 120 seconds, and left to stand at room temperature for 24 hours. Through secondary high-temperature setting, the distribution stability of the antibacterial agent is strengthened, and at the same time, the air permeability of the fabric is ensured not to be damaged.

[0020] Preferably, the implementation steps of step S4 are as follows: After the binder mainly composed of polyacrylate is melted at high temperature and quickly cooled to 45°C, it is stirred at a low speed for 2 minutes with the rose essential oil solution loaded in the microcapsules in a closed container to form a uniform mixture, ensuring that the binder is fully combined with the aromatherapy microcapsules and providing a stable carrier for the subsequent impregnation process.

[0021] Preferably, the implementation steps of step S5 are as follows: Immerse the base cloth in the mixture of aromatherapy microcapsules and penetrating binder for 30 seconds, with a liquor ratio of 75-80%, and then treat it in a stenter at 110°C for 90 seconds. Through impregnation and high-temperature setting, the fragrance microcapsules are evenly embedded in the fiber pores to achieve the fragrance slow-release function.

[0022] Preferably, the implementation steps of step S6 are as follows: Place the aromatherapy microcapsule mixture in a low-temperature closed container, slowly heat it up to 45°C in 30 minutes, and maintain a constant temperature for 10 minutes. Adopt staged temperature control to avoid microcapsule rupture and improve the loading efficiency.

[0023] Preferably, the implementation steps of step S7 are as follows: Mix 0.5-1% wormwood powder with a particle size <100 microns with 2-4% silica gel, and use a dispensing device to dispense it on the surface of the base cloth in small micro-patterns, and cure it at 25°C for 40 seconds to form a dispensing layer with a massage function, while releasing the health-care components of wormwood, and the wash resistance > 100 times.

[0024] Preferably, the implementation steps of step S8 are as follows: Add nano-silver microcapsule auxiliaries with a pH value of 6.8 - 7 to the impregnation treatment solution, soak the base fabric for 10 minutes, optimize the pH value to enhance the activity of nano-silver ions and improve the antibacterial efficiency.

[0025] The present invention also provides a health-care scented knitted fabric, which includes ordinary fibers, porous microcapsules loaded with rose essential oil, microcapsules loaded with nano-silver ions, natural plant extract wormwood powder, and silicone mixed wormwood powder dotting. The ordinary fiber is one of cotton fiber and polyester fiber.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows: Through the porous microcapsule loading technology, staged temperature control and dynamic pH regulation, combined with the silicone dotting process design, the production process of the health-care scented knitted fabric achieves the core advantages of long-term slow-release fragrance, high-efficiency antibacterial, optimized air permeability and compound health-care functions. At the same time, it takes into account process stability and multi-scenario applicability, solves the problem that traditional fabrics cannot load health-care ingredients when adding them, and adding natural fibers with health-care effects through blended spinning results in a 20% - 30% decrease in fiber strength. At the same time, the fragrance is more lasting and the fabric is lighter and thinner. Specific embodiments
