Description

Technical Field

[0001] The invention belongs to the technical field of textile fabrics, and in particular relates to a quick-drying antibacterial colored cellulose fabric and a preparation method thereof. Background Art

[0002] Cellulose fabrics are widely used in T-shirts, vests, trousers, and skirts. Pure cotton apparel is particularly popular in the fashion market and has become a must-have for all seasons. In the sweltering summer heat, people increasingly demand higher levels of moisture absorption, breathability, and antibacterial properties in clothing. Cotton fibers, due to their high hygroscopicity, absorb large amounts of sweat, causing the fabric to become wet and heavy. This slows down moisture conduction and release, affecting the microclimate between the skin and the garment, as well as heat and moisture exchange between the garment and the outside world. Furthermore, they take a long time to dry, making them uncomfortable to wear. Furthermore, these fabrics can also harbor the disadvantage of bacterial growth and odor generation.

[0003] People's requirements for fabrics are no longer limited to breathability and moisture absorption. Multifunctional textiles with cooling, quick-drying, antibacterial, and self-cleaning properties are becoming more and more popular. Fabrics and clothing with quick-drying and antibacterial functions are in great demand in the summer, and the development of fabrics with quick-drying and antibacterial properties has become a hot topic in the industry. Existing quick-drying fabric technology mainly adds jade powder to polyester or nylon yarn or weaves mesh structure fabrics. Such fabrics can only achieve instant heat conduction. After absorbing moisture, such fabrics easily adhere to the skin surface, resulting in a poor wearing experience. Cellulose fabrics are hydrophobically finished to reduce the hygroscopicity of the fibers. The finishing method is generally to combine post-finishing auxiliaries with fabrics. Such fabrics have poor wash resistance and stability, and reduce the comfort of the fabric, resulting in a poor wearing experience. In addition, the existing technology also uses different weaving methods to produce heat-conducting and perspiration-wicking clothing fabrics to achieve different effects. Since such fabrics need to be woven into different organizational structures, the production process is complicated and the cost is high, and the stability of the weaving structure is not good.

[0004] To address the bacterial growth caused by perspiration, antimicrobial properties have been imparted to textiles. Currently, antimicrobial fabrics are typically manufactured by grafting or coating functional additives onto fabric fibers through chemical crosslinking or impregnation. Commonly used antimicrobial agents include organic compounds (such as quaternary ammonium compounds, triclosan, and polyhexamethylene biguanide), synthetic or natural polymers (such as polypyridine, chitosan, and antimicrobial peptides), and metal-based materials (such as copper, silver, and zinc, as well as their oxides and salts). If textiles could retain their color while also possessing multifunctionality, their applications would be broadened, significantly increasing their added value.

[0005] At present, cellulose fiber has the characteristics of excellent moisture absorption and air permeability, and its application scope is gradually expanding, but its use in the development of quick-drying and antibacterial colored cellulose fabrics has not been reported. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a quick-drying and antibacterial colored cellulose fabric and its preparation method, so as to solve the discomfort caused by sweat remaining on the body surface due to increased body temperature during wearing of cellulose fiber fabric. By rearranging the cellulose fiber molecules, a colored cellulose fabric with strong hydrophobicity is formed, which increases the diffusion rate of liquid and heat transfer, maintains the balance of human body temperature, and improves the wearing experience; and it is of great significance to solve the problem of bacterial damage to the human body.

[0007] The invention provides a quick-drying antibacterial colored cellulose fabric, which is obtained by interweaving and blending an inner layer fabric and an outer layer fabric; the inner layer fabric is obtained by blending hydrophobic antibacterial colored fibers and phase-change viscose fibers; and the outer layer fabric is obtained by blending hydrophobic antibacterial colored fibers and dyed cellulose fibers.

[0008] Preferably, the mass fraction of the hydrophobic and antibacterial colored fibers in the inner layer fabric is 85%-95%; the mass fraction of the phase change viscose fibers is 5%-15%.

[0009] Preferably, the mass fraction of the hydrophobic and antibacterial colored fibers in the outer fabric is 70%-80%; the mass fraction of the dyed cellulose fibers is 20%-30%.

[0010] Preferably, the hydrophobic antibacterial colored fiber is obtained by complexing copper ions with cellulose fiber A.

[0011] Preferably, the phase change viscose fiber is a phase change viscose fiber containing menthol.

[0012] Preferably, the dyed cellulose fibers are obtained from cellulose fibers B by dyeing.

[0013] Preferably, the cellulose fiber A and the cellulose fiber B are selected from at least one of cotton fiber, modal fiber and viscose fiber.

[0014] Preferably, the mass fraction of the inner layer fabric in the fabric is 40%-50%.

[0015] The present invention also provides a method for preparing a quick-drying antibacterial colored cellulose fabric, comprising the following steps:

[0016] (1) pretreating cellulose fiber A;

[0017] (2) The pretreated cellulose fiber A was immersed in tetrahydroxy copper ([Cu(OH)4] 2- ) solution to obtain a hydrophobic antibacterial colored fiber;

[0018] (3) dyeing the cellulose fiber B;

[0019] (4) The hydrophobic antibacterial colored fiber and phase change viscose fiber are blended as the inner layer fabric, and the dyed cellulose fiber B and the hydrophobic antibacterial colored fiber are woven as the outer layer fabric. The inner layer fabric and the outer layer fabric are interwoven and blended to obtain a quick-drying antibacterial colored cellulose fabric.

[0020] Preferably, the pretreatment in step (1) is specifically as follows: cellulose fiber A is immersed in a sodium carbonate solution; wherein the concentration of the sodium carbonate solution is 0.5-1 g / L, the bath ratio is 1:40-60, the immersion time is 5-20 min, and the temperature is 80-100°C.

[0021] Preferably, the preparation method of the tetrahydroxycopper solution in step (2) is: dissolving sodium hydroxide in distilled water at the temperature of an ice water bath to obtain a sodium hydroxide solution; and then adding a copper sulfate solution to the sodium hydroxide solution to obtain a tetrahydroxycopper solution.

[0022] Preferably, the concentration of the tetrahydroxycopper solution is 0.015 mol / L-0.025 mol / L.

[0023] Preferably, the concentration of the sodium hydroxide solution is 20-30 wt%.

[0024] Preferably, the bath ratio of the cellulose fiber A in the step (2) to the tetrahydroxycopper solution is 1:100.

[0025] Preferably, the hydrophobic antibacterial colored fibers in step (2) are washed and dried before subsequent blending.

[0026] Preferably, the drying times are 2-3 times, the interval time is 4-6 hours, the drying time is 10-30 minutes, and the temperature is 30-40°C.

[0027] The principles of the present invention are as follows:

[0028] In the prior art, hydrophobic modification of cellulose fibers is often performed using hydrophobic additives to modify the fibers, causing hydrophobic groups to attach to the fiber surface to achieve a hydrophobic effect, which in turn damages the fiber's moisture absorption and conductivity and skin-friendliness. Moreover, current colored cellulose fabrics are often woven from dyed yarns and natural yarns or made from yarns dyed with dyes of different colors, and do not have certain functionality.

[0029] The present invention provides a method different from dyeing with dyes, which can make cellulose fibers have different colors and reduce the dyeing process. The present invention uses the color characteristics and antibacterial functionality of copper ions themselves to give cellulose fiber fabrics quick-drying, antibacterial and anti-ultraviolet functions, breaking the limitations of cellulose fibers that have poor moisture absorption and quick-drying properties and are prone to bacteria in humid environments. The preparation of hydrophobic antibacterial colored fibers is to first use sodium hydroxide solution to open the crystalline area of ​​the fiber, and then complex it with copper ions to give the yarn function and color. The principle is to use sodium hydroxide solution to break the cellulose hydrogen bond network, embed copper ions into the gaps between cellulose crystals, and coordinate with the exposed oxygen-containing polar functional groups (such as hydroxyl groups) on the cellulose chain, so that more copper ions are adsorbed in the fiber to produce color. The advantage of this dyeing method is that the processing conditions are mild and the fiber is treated under immersion conditions, so the fiber's moisture conductivity can be retained. In addition, the fiber produced by this dyeing method also has excellent antibacterial properties because the fiber contains a large amount of copper ions. By designing the fabric's structure and utilizing its hydrophobicity, the diffusion rate of liquid can be accelerated, the drying rate can be increased, and the fabric can have good quick-drying properties.

[0030] The quick-drying antibacterial colored cellulose fabric of the present invention has an antibacterial rate of more than 90% against Escherichia coli and an antibacterial rate of more than 85% against Staphylococcus aureus. The antibacterial performance test method refers to GB / T20944.3-2008 "Evaluation of Antibacterial Properties of Textiles Part 3: Oscillation Method"; the soaking time of the quick-drying antibacterial colored cellulose fabric is 6.1-20.0s, the water absorption rate is 30-80.0% / s, the maximum soaking radius is 12.1-22mm, and the liquid water diffusion rate is 3.1-4.0mm / s. The test methods for the soaking time, water absorption rate, maximum soaking radius, and liquid water diffusion rate all refer to GB / T 21655.2-2019 "Evaluation of Moisture Absorption and Quick-drying Properties of Textiles Part 2: Dynamic Moisture Transfer Method"; the anti-ultraviolet UPF of the quick-drying antibacterial colored cellulose fabric is greater than 50, UVA is less than 5%, and UVB is less than 5%. The antibacterial performance test method refers to GB / T 18830-2009 “Evaluation of UV Protection Performance of Textiles”.

[0031] Beneficial effects

[0032] (1) The quick-drying and antibacterial colored cellulose fabric prepared by the present invention has 100% cellulose fiber component fabric, which keeps the fiber skin-friendly and breathable, and has excellent moisture absorption and quick-drying, antibacterial and anti-ultraviolet effects, and alleviates the stuffiness caused by the high hygroscopicity of cellulose fiber. The hydrophobic antibacterial colored fiber contained in the fabric improves the liquid transfer rate and increases the liquid evaporation rate, which can effectively improve the quick-drying performance, antibacterial and anti-ultraviolet effects of the fabric; the entire production process of the present invention reduces the post-finishing process flow, and the finished fabric exhibits good wash resistance, and has good application prospects.

[0033] (2) The copper ions of the hydrophobic antibacterial colored fiber prepared by the present invention are rarely reduced during the preparation process. The yarn is treated under alkaline conditions to quickly complex the copper ions. The modified yarn has a certain color, which reduces the dyeing process of the fabric. Due to the presence of copper ions, the yarn has good antibacterial properties, high bonding fastness, and good washability.

[0034] (3) The copper ions in the present invention are both antimicrobial modifiers and complex reaction solvents. Sodium hydroxide is used to destroy the cellulose chains, break the cellulose hydrogen bond network, embed the copper ions into the gaps between the cellulose crystals, and coordinate with the cellulose to impart antimicrobial properties. The hydrophobic modification and in-situ antimicrobial modification are completed in only one step, shortening the process time.

[0035] (4) The phase change viscose fiber in the present invention can automatically adjust the microclimate between the skin and clothing, increase the evaporation rate of liquid, and the fabric has good quick-drying performance. DETAILED DESCRIPTION

[0036] Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiments are only used to illustrate the present invention and are not used in limiting the scope of the present invention.In addition, should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall equally within the scope limited by the appended claims of the application.

[0037] Example 1

[0038] (1) Preparation of raw materials:

[0039] The preparation steps of the hydrophobic antibacterial colored fiber are as follows:

[0040] (a) Pretreatment: The cotton fibers were immersed in a 1 g / L sodium carbonate solution for 10 min, with a bath ratio of 1:50 and a temperature of 90°C, and then washed with water and dried.

[0041] (b) using a tetrahydroxy copper solution to modify cotton fibers, the specific process is as follows:

[0042] Sodium hydroxide is dissolved in distilled water in an ice water bath to obtain a sodium hydroxide solution with a concentration of 20wt%; copper sulfate solution is then slowly added to the sodium hydroxide solution to obtain a tetrahydroxycopper solution; the cotton fiber is immersed in a tetrahydroxycopper solution with a temperature of 25°C and a concentration of 0.025mol / L according to a bath ratio of 1:100 for 12 hours, and then washed and dried (drying times are 3 times) with an interval of 4 hours, a drying time of 15 minutes, and a temperature of 30°C to obtain a hydrophobic and antibacterial colored fiber, whose soap fastness (the soap fastness test method refers to GB / T3921-2008 "Textiles - Tests for Color Fastness - Color Fastness to Washing", the same below) is grade 3-4.

[0043] The dyeing process of the outer layer of dyed cotton fibers is gradient temperature dyeing, the dyeing rate is 70%, and the soaping fastness is 3-4 grade. Specifically, first, the cotton fibers are added to the dyeing solution at a temperature of 40°C, then the temperature is raised to 85°C at a rate of 1°C / min and kept for 60 min; the dyeing solution is obtained by adding reactive brilliant red K-2G, JFC and sodium sulfate (sodium sulfate) to water, the mass fraction of reactive brilliant red K-2G in the dyeing solution is 2% owf, the concentration of sodium sulfate is 40 g / L, the concentration of soda ash is 20 g / L, and the concentration of JFC is 0.2 g / L; the bath ratio of cotton fibers to dyeing solution is 1:40.

[0044] (2) Selecting hydrophobic antibacterial colored fiber / phase change viscose fiber (90:10) blend as the inner layer fabric, and hydrophobic antibacterial colored fiber and dyed cotton fiber blended with modal (70:15:15) as the outer layer fabric, the inner and outer layers are blended at a ratio of 1:1 to prepare a quick-drying antibacterial colored cellulose fabric with a grammage of 175 g / m 2 .

[0045] The prepared quick-drying antibacterial colored cellulose fabric has an antibacterial rate of 95% against E. coli and 90% against S. aureus, and after 100 washes, the antibacterial rate against E. coli is 85% and the antibacterial rate against S. aureus is 80%; the wetting time of the quick-drying antibacterial colored cellulose fabric is 10 s, the water absorption rate is 70% / s, the maximum wetting radius is 15 mm, and the liquid water diffusion speed is 3.2 mm / s; the quick-drying antibacterial colored cellulose fabric has an ultraviolet resistance UPF of 70, a UVA of 2.8%, and a UVB of 3%, and the fabric has a relatively soft and elastic hand feeling.

[0046] Comparative Example 1

[0047] The preparation method is basically the same as that of Example 1, except that the copper sulfate solution is replaced by a cotton fiber soaking solution.

[0048] The prepared colored cellulose fabric has no antibacterial properties against E. coli and S. aureus; the wetting time of the colored cellulose fabric is 1 s, the water absorption rate is 200% / s, the maximum wetting radius is 8 mm, and the liquid water diffusion speed is 1.5 mm / s; the quick-drying antibacterial colored cellulose fabric has an ultraviolet resistance UPF of 25, a UVA of 6%, and a UVB of 7.3%, and the fabric has a relatively soft and elastic hand feeling.

[0049] Compared with Example 1, the wetting time, water absorption rate, maximum wetting radius and antibacterial performance of the fabric of Comparative Example 1 are worse than those of Example 1. This is because the hydrophobicity and antibacterial properties of Comparative Example 1 are attributed to the presence of copper ions, and the adsorption amount of copper ions is mainly determined by the concentration of sodium hydroxide. Therefore, the yarn of Comparative Example 1 that has not been treated with sodium hydroxide has zero adsorption of copper ions, which makes the copper ion content in the fabric zero, and therefore the antibacterial performance is poor.

[0050] Comparative Example 2

[0051] The preparation method is basically the same as that in Example 1, except that the cotton fiber is immersed in a sodium hydroxide solution instead of a tetrahydroxycopper solution, that is, the cotton fiber is immersed in a 20wt% sodium hydroxide solution at a bath ratio of 1:100 for 12 hours, washed with water, and dried three times with an interval of 4 hours, a drying time of 15 minutes, and a temperature of 30°C to obtain a colored fiber.

[0052] The prepared quick-drying and antibacterial colored cellulose fabric has no antibacterial performance against Escherichia coli and Staphylococcus aureus; the quick-drying and antibacterial colored cellulose fabric has a wetting time of 1s, a water absorption rate of 200% / s, a maximum wetting radius of 10mm, and a liquid water diffusion rate of 2mm / s; the quick-drying and antibacterial colored cellulose fabric has an anti-ultraviolet UPF of 25, a UVA of 6.2%, and a UVB of 7%, and the fabric feels relatively soft and elastic.

[0053] Compared to Example 1, the fabric of Comparative Example 2 exhibited poorer wetting time, water absorption rate, maximum wetting radius, and antibacterial properties than those of Example 1. This is because the hydrophobicity and antibacterial properties of Comparative Example 2 are attributed to the presence of copper ions, and the amount of copper ion adsorption is primarily determined by the copper ion concentration. When the copper ion concentration is zero, there are no copper ions on the yarn, resulting in poor antibacterial properties of the yarn of Comparative Example 2 treated with sodium hydroxide.
