Description

Technical Field

[0001] This invention relates to the field of textile technology, specifically to a silk-smooth antibacterial and deodorizing yarn, spinning process, and fabric. Background Technology

[0002] As people's demands for quality of life increase, their requirements for textiles are also rising. Functionality is a significant trend in textile development, with antibacterial and deodorizing properties becoming a core research and development direction in the textile industry due to their direct connection to human health and user experience. As a crucial barrier between the human body and the environment, fabrics are prone to bacterial growth under suitable temperature and humidity conditions during daily use. This not only produces odors affecting the wearing experience but may also cause skin irritation. Therefore, the demand for yarn products with stable antibacterial and deodorizing properties is increasingly urgent.

[0003] Currently, the main way to achieve antibacterial and deodorizing functions in yarn is to add antibacterial and deodorizing agents during the spinning process. Developing an antibacterial and deodorizing agent that can achieve long-lasting antibacterial properties and has excellent deodorizing effects is very important to ensure the antibacterial and deodorizing effects of yarn. Summary of the Invention

[0004] This invention proposes a silk-soft antibacterial and deodorizing yarn, spinning process, and fabric, which solves the problem of insufficient antibacterial durability of yarn in related technologies, while maintaining excellent deodorizing effect.

[0005] The technical solution of the present invention is as follows: This invention proposes a spinning process for silky soft antibacterial and deodorizing yarn, comprising the following steps: S1. Preparation of antibacterial and deodorizing cotton web: The combed cotton web is subjected to antibacterial and deodorizing treatment to obtain antibacterial and deodorizing combed cotton web; S2. Cleaning: The antibacterial and deodorizing combed cotton web is sequentially subjected to cotton grabbing, cotton mixing, opening, impurity removal and roll forming to produce an antibacterial and deodorizing cotton roll; S3. Carding: The antibacterial and deodorizing cotton roll is carded and impurities are removed to make antibacterial and deodorizing cotton strips; S4. Drawing: The antibacterial and deodorizing cotton sliver is combined with the combed cotton sliver that has not been treated with antibacterial and deodorizing treatment and then drawn to obtain a primary mixed cotton sliver. The primary mixed cotton sliver is then drawn twice more to obtain a finished sliver. S5. Spinning: The sliver is drawn, falsely twisted, twisted and wound to obtain a silky, antibacterial and deodorizing yarn. The antibacterial and deodorizing finishing agent used in the antibacterial and deodorizing treatment comprises the following components in parts by weight: 11-17 parts antibacterial and deodorizing agent, 2-4 parts thickener, 0.6-1.2 parts antistatic agent, and 80-100 parts water; The antibacterial and deodorizing agent comprises 3-5 parts of alumina-supported titanium dioxide and 8-12 parts of natural additives.

[0006] As a further technical solution, the method for preparing the combed cotton web includes the following steps: Cotton is processed through processes such as cotton grabbing, blending, opening, impurity removal, lap forming, combing, impurity removal, sliver forming, pre-combining, sliver lap forming and combing to obtain a combed cotton web.

[0007] As a further technical solution, the method for preparing the untreated combed cotton sliver includes the following steps: Cotton is processed through grabbing, blending, opening, impurity removal, lapping, combing, impurity removal, sliver forming, pre-combining, sliver lapping and combing to obtain combed cotton slivers that have not undergone antibacterial and deodorizing treatment.

[0008] As a further technical solution, the mass ratio of the antibacterial and deodorizing tampons to the untreated combed tampons is 1:9 to 3:7.

[0009] As a further technical solution, the method for preparing the alumina-supported titanium dioxide includes the following steps: S1. Add tetrabutyl titanate to anhydrous ethanol and stir to form solution I; add anhydrous ethanol to nitric acid, then add water and stir to form solution II; add solution II dropwise to solution I and stir to obtain titanium dioxide sol. S2. Immerse the alumina in the titanium dioxide sol, remove excess sol, dry, and calcine to obtain alumina-supported titanium dioxide.

[0010] As a further technical solution, the alumina is α-alumina and γ-alumina in a mass ratio of 0.4:2.8~3.5.

[0011] In this invention, when titanium dioxide is loaded onto alumina, the alumina used is α-alumina and γ-alumina in a mass ratio of 0.4:2.8~3.5, which further improves the antibacterial durability of the yarn.

[0012] As a further technical solution, in solution I, the mass ratio of tetrabutyl titanate to anhydrous ethanol is 1:1.5~2.5.

[0013] As a further technical solution, the stirring speed is 400~600 rpm and the stirring time is 8~12 min.

[0014] As a further technical solution, the volume concentration of the nitric acid is 64%~68%.

[0015] As a further technical solution, in solution II, the mass ratio of nitric acid, anhydrous ethanol and water is 1:5:3~4.

[0016] As a further technical solution, the dripping rate is 2~3 drops / s.

[0017] As a further technical solution, the mass ratio of alumina to tetrabutyl titanate is 1:4~5.

[0018] As a further technical solution, the immersion time is 3-5 hours.

[0019] As a further technical solution, the drying temperature is 25~35℃ and the time is 2~3h.

[0020] As a further technical solution, the calcination temperature is 105~125℃ and the time is 55~75min.

[0021] As a further technical solution, the calcination atmosphere is air.

[0022] As a further technical solution, the natural additives include one or more of neem oil, lavender oil, and tea polyphenols.

[0023] As a further technical solution, when the natural adjuvant is neem oil, lavender oil and tea polyphenols, the mass ratio of neem oil, lavender oil and tea polyphenols is 0.1:0.4:1.8~2.4.

[0024] The antibacterial and deodorizing finishing agent for the silk-spun antibacterial and deodorizing yarn of this invention incorporates neem oil, lavender oil, and tea polyphenols as natural auxiliaries. While maintaining antibacterial durability, it can significantly improve the deodorizing properties of the antibacterial and deodorizing yarn, enabling the yarn to achieve a rapid deodorizing effect.

[0025] As a further technical solution, the thickener includes carboxymethyl cellulose.

[0026] As a further technical solution, the antistatic agent includes octadecyltrimethylammonium chloride.

[0027] A silk-spun antibacterial and deodorizing yarn is made by the spinning process of the aforementioned silk-spun antibacterial and deodorizing yarn.

[0028] A fabric made from the aforementioned silky antibacterial and deodorizing yarn.

[0029] The working principle and beneficial effects of this invention are as follows: In this invention, the addition of alumina-loaded titanium dioxide to the antibacterial and deodorizing finishing agent significantly improves the antibacterial durability of the yarn. The antibacterial and deodorizing finishing agent also contains natural auxiliaries: neem oil through chemical reaction and physical adsorption, lavender oil through odor masking and inhibition of microorganisms, and tea polyphenols through chemical reaction and inhibition of microbial growth. These three synergistically enhance the yarn's deodorizing effect. This invention first prepares the combed cotton web and then performs antibacterial and deodorizing treatment, avoiding the common industry problem of excessive neps and fiber breakage caused by directly treating the fibers initially, which leads to damage to the modified fibers during subsequent vigorous carding and combing processes. This facilitates the subsequent spinning of high-quality yarn. Titanium dioxide achieves its antibacterial effect through photocatalysis, and alumina acts as a carrier to fix titanium dioxide onto the alumina, optimizing the antibacterial longevity and activity of titanium dioxide and significantly improving the yarn's antibacterial durability.

[0030] The silky antibacterial and deodorizing yarn prepared in this invention is an innovative pure cotton yarn with high softness and low fuzz, precisely meeting the consumption trend of healthy and comfortable textiles. It has the advantages of soft and smooth feel, low fuzz, high strength and toughness, and large fiber microspace. It is suitable for the needs of infant, children's clothing, homewear and high-end bedding scenarios. It adopts Siro compact spinning and innovative false twist spinning technology, which applies twist while stretching, and ensures that the yarn strength is not reduced while reducing the twist by 15%, optimizing the balance between fuzz and strength, and combining a soft and smooth cotton feel with durability.
