Description

Technical Field

[0001] This invention relates to a mask base fabric with antibacterial and deodorizing functions and its preparation method, belonging to the field of nonwoven fabrics. Background Technology

[0002] Sheet masks are fast-moving consumer goods in the beauty market, occupying a significant share of the mask market. Currently, the carrier of sheet masks is mainly non-woven material mask base fabric, primarily spunlace non-woven material, using mainly natural cellulose fibers and regenerated cellulose fibers as raw materials. Many functional ingredients in mask essences have chemically irritating odors that can cause discomfort to some users, thus often requiring the addition of fragrances to mask them. However, the addition of fragrances increases the burden on the skin. Ordinary mask base fabrics cannot directly eliminate the irritating odors of the functional ingredients in the essence. Therefore, this invention proposes a mask base fabric with antibacterial and deodorizing functions. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a mask base fabric with antibacterial and deodorizing functions and its preparation method.

[0004] This invention is implemented as follows:

[0005] The present invention first provides a mask base fabric with antibacterial and deodorizing functions, which is prepared by mixing thermoplastic polyester elastomer (TPEE), lyocell fiber (Tel) and caprolactone fiber.

[0006] Furthermore, the TPEE fiber has a fineness of 2.62 dtex, the Tel fiber has a fineness of 0.9-1.33 dtex, and each fiber has a length of 38 mm, including Kaplon fiber.

[0007] The Lyocell fiber used in this invention is extracted from wood pulp and has the characteristics of good moisture absorption, antibacterial properties, and environmental friendliness. This invention uses Lyocell fiber with a density of 0.9-1.33 dtex, which has a fine fiber fineness and helps to improve the feel of the product.

[0008] The copper ion fiber used in this invention has a moisture regain rate similar to cotton, exhibiting good moisture absorption and breathability, and possessing strong and long-lasting antibacterial, deodorizing, and self-cleaning functions. Copper-containing antibacterial fiber is a functional fiber with effects such as blocking disease transmission, eliminating odors, and repairing skin, making it a new type of safe antibacterial textile. Other copper ion fiber fabrics generally require an addition of 40-50% or more to achieve antibacterial and deodorizing effects. However, adding only 5% to the copper ion fiber in the copper ion fiber fabric provides highly effective antibacterial and deodorizing effects. Because the proportion of copper ion fiber used is small, it does not affect processing performance, therefore the fiber fineness is not limited.

[0009] Furthermore, the mass ratio of each fiber is as follows: TPEE 35-45%, Tel 35-45%, and Kapron fiber 10-30%, with the total percentage being 100%.

[0010] The present invention also provides a method for preparing the mask base fabric, including weighing raw materials → mixing and loosening → carding into a web (cross-laying web) → hydroentanglement reinforcement → drying → winding and cutting.

[0011] Specifically, the steps include the following:

[0012] (1) Fiber blending: Thermoplastic polyester elastomer (TPEE), Lyocell fiber (Tel), and Kaplon fiber are blended to obtain the base fabric;

[0013] (2) Opening: The base fabric is opened;

[0014] (3) Combing: Combing the loosened base fabric;

[0015] (4) Web formation: The combed base fabric is laid in a cross-laying method;

[0016] (5) Hydroentangling reinforcement;

[0017] (6) Drying;

[0018] (7) Finished product: Cut the dried base fabric and roll it up to obtain the mask base fabric.

[0019] This invention has the following advantages: It uses TPEE polyester fiber, which has strong water absorption, high strength, good tensile elongation and softness, low initial modulus, low rigidity, and is easy to bend. The caprolactone fiber used contains copper ions, which can effectively and persistently provide antibacterial, deodorizing, and self-cleaning properties. The mask base fabric of this invention can remove the odor of many functional ingredients in the mask essence and can also effectively eliminate various bacteria and fungi generated on the human face during the mask production process.
