Description

Technical Field

[0001] The invention relates to the technical field of fabrics, and in particular to a polyester fabric with antibacterial and moisture-absorbing functions and a production process thereof. Background Art

[0002] With the rapid improvement of living standards, people's demand for fabrics has gradually diversified. Polyester fabric is a synthetic fiber fabric, mainly composed of polyester fiber. Usually, in order to meet the needs of different products, it is often blended with other fibers. Polyester fiber is also called polyester fiber. The composition is polyethylene terephthalate. Fabrics made of polyester fiber have wear resistance and good elasticity, are not easy to deform, not easy to wrinkle, can maintain a good appearance, have good heat resistance, are not easy to fade, and are not easily damaged by bleaching agents, etc. However, fabrics made of polyester fiber also have shortcomings, such as poor moisture absorption. In the hot summer environment, human skin sweat cannot be absorbed in time. and diffusion, resulting in sweat retention on the skin surface causing stuffiness and discomfort. In severe cases, it may even cause skin problems, leading to eczema or prickly heat. Polyester fabrics with poor hygroscopicity will produce static electricity in a dry environment, causing the polyester fabric to absorb dust and hair, affecting the hygiene of the fabric. Polyester fabrics with poor hygroscopicity usually have poor warmth retention because the sweat on the skin surface cannot evaporate in time and takes away the heat. In addition, polyester fabrics have poor antibacterial properties. Due to poor hygroscopicity, sweat is retained on the fabric surface, creating a humid growth environment for bacteria and other microorganisms. Therefore, the shortcomings of polyester fabrics limit their application, and the modification of polyester fabrics is worthy of study.

[0003] The patent with publication number CN110606944B discloses a mildew-proof polyester with high washing resistance and a preparation method thereof. The mildew-proof polyester uses terephthalic acid and ethylene glycol as starting materials. After the esterification reaction of terephthalic acid and ethylene glycol is completed, a modifier is added to participate in the polymerization reaction to obtain a modified mildew-proof polyester. Organic silicon and quaternary ammonium salt are introduced in a chemically bonded manner. The N positive ions in the quaternary ammonium salt are combined on the fiber surface in the form of chemical bonds, thereby attracting negatively charged fungi and bacteria to restrain the activity of the bacteria and enter through the bacterial cell membrane. In its cells, it destroys the metabolism of enzymes in bacteria and causes cell death, thereby achieving the effect of sterilization or inhibiting bacterial growth. It is combined in the form of chemical bonds and is not easy to fall off. It has strong wash resistance and can maintain the antibacterial and mildew-proof properties of polyester fabrics for a long time. However, this patent does not take into account the poor hygroscopicity of polyester fabrics, which will cause discomfort, promote the breeding and reproduction of bacteria, and limit the application of polyester fabrics. Therefore, the present invention provides a polyester fabric with antibacterial and hygroscopic functionality, which has excellent hygroscopicity and antibacterial properties, broadens the application range of polyester fabrics, and improves the wearing experience. Summary of the invention

[0004] To solve the problems mentioned in the background art, the object of the present invention is to provide a polyester fabric with antibacterial and moisture-absorbing functions and its production process.

[0005] The object of the present invention can be achieved by the following technical solutions:

[0006] A production process of a polyester fabric with antibacterial and moisture-absorbing functions, comprising the following steps:

[0007] The first step: Prepare modified composite polyester fibers and functional fibers respectively;

[0008] The second step: Place 75-85 parts by weight of modified composite polyester fibers and 30-40 parts of functional fibers in a spinning machine to spin into yarns, and then place the two spun yarns in a weaving machine to weave to obtain a grey cloth;

[0009] The third step: Place the grey cloth in an overflow machine for desizing and scouring, set the temperature at 90-105 °C, and the treatment time at 50-80 min to obtain the treated grey cloth;

[0010] The fourth step: Immerse the treated grey cloth in clear water and then roll it, dry it at a temperature of 70-85 °C for 5-15 min, and bake it at a temperature of 100-120 °C for 3-6 min to obtain a fabric layer;

[0011] The fifth step: Immerse the fabric layer in an amino silicone softener at room temperature and roll it, and obtain the polyester fabric after drying and cooling.

[0012] Further, the preparation method of the modified composite polyester fibers comprises the following steps:

[0013] Step A: Add polyester fibers to an acetone solution, soak for 16-18 h, then wash and dry them with deionized water, and put the dried polyester fibers into a plasma generator for treatment to obtain treated polyester fibers;

[0014] Step B: Add the treated polyester fibers to dimethyl sulfoxide, stir and mix evenly, add a halogen isocyanate modifier and catalyst A, raise the temperature to 60-75 °C, stir and react for 3-5 h, then filter, wash, and dry to obtain modified polyester fibers;

[0015] Step C: Add the modified polyester fibers and bacterial cellulose to N,N-dimethylformamide, mix evenly, add triethylamine, raise the temperature to 65-75 °C, react for 2-5 h, then separate the product, wash, and dry to obtain modified composite polyester fibers.

[0016] By adopting the above technical solution, after the polyester fiber is treated by a plasma generator, the oxygen-containing functional group hydroxyl on the surface increases, and the treated polyester fiber is obtained. Under the action of catalyst A, the hydroxyl group on the surface of the treated polyester fiber reacts with the isocyanate in the structure of the halogen isocyanate modifier, and a halogen substituent is introduced on the surface of the treated polyester fiber to obtain a modified polyester fiber. The halogen substituent on the surface of the modified polyester fiber can undergo a substitution reaction with the hydroxyl group in bacterial cellulose under the action of triethylamine to obtain a modified composite polyester fiber.

[0017] Further, in step A, the treatment by the plasma generator is to first evacuate and then introduce oxygen for treatment for 60 - 80 s, adjust the pressure to 45 - 55 Pa, and the power to 35 - 45 W.

[0018] Further, in step B, the halogen isocyanate modifier is any one of chloroethyl isocyanate, 4-chlorophenyl isocyanate or 3-chloropropyl isocyanate.

[0019] Further, in step B, the catalyst A is dibutyltin dilaurate or stannous octoate.

[0020] Further, the preparation method of the functional fiber includes the following steps:

[0021] Step T1: Add bamboo fiber into a potassium hydroxide solution, stir evenly, then raise the temperature to 40 - 45 °C, oscillate for 1 - 2 h under the condition of 100 - 200 r / min, wash, filter by suction, and dry to obtain pretreated bamboo fiber;

[0022] Step T2: Disperse the pretreated bamboo fiber in a toluene solution to form a uniform suspension, add a diglycidyl ether modifier and catalyst B, mix evenly, then raise the temperature to 60 - 70 °C, stir for 3 - 5 h, filter, wash, and dry to obtain modified bamboo fiber;

[0023] Step T3: Disperse the modified bamboo fiber in N,N-dimethylformamide to form a uniform suspension, add 2-mercaptopyridine-N-oxide and tetrabutylammonium fluoride, mix evenly, then raise the temperature to 40 - 50 °C, react for 4 - 6 h, filter by suction, wash, and dry to obtain the functional fiber.

[0024] By adopting the above technical solution, after treatment with the potassium hydroxide solution, more hydroxyl groups on the surface of bamboo fibers can be exposed, and the pores increase, obtaining pretreated bamboo fibers. The hydroxyl groups contained on the surface of the pretreated bamboo fibers can react with the epoxy groups in the structure of the diglycidyl ether modifier under the action of catalyst B, thereby introducing epoxy groups into the bamboo fibers to obtain modified bamboo fibers. Under the action of tetrabutylammonium fluoride, the epoxy groups on the surface of the modified bamboo fibers can react with the mercapto groups in the structure of 2-mercaptopyridine-N-oxide to obtain functional fibers.

[0025] Further, in step T1, the mass fraction of the potassium hydroxide solution is 10 - 15%.

[0026] Further, in step T2, the diglycidyl ether modifier is any one of ethylene glycol diglycidyl ether, neopentyl glycol diglycidyl ether, or 1,4-butanediol diglycidyl ether.

[0027] Further, in step T2, the catalyst B is boron trifluoride diethyl etherate.

[0028] A polyester fabric with antibacterial and moisture-absorbing functions is prepared by adopting the above production process.

[0029] The beneficial effects of the present invention:

[0030] (1) The modified composite polyester fiber prepared by the present invention combines polyester fiber with bacterial cellulose organically. Bacterial cellulose has high strength and high elastic modulus. On the one hand, it can improve the mechanical properties of the fabric, avoid damage caused by the decrease in strength during long-term use of the fabric, reduce the service durability of the fabric, and effectively improve the durability of the fabric; on the other hand, the porous network structure of bacterial cellulose can provide more adsorption sites for water molecules, enhance the moisture absorption performance of the fabric, contribute to the sweating and breathability of the fabric. In addition, bacterial cellulose has good skin compatibility, can improve the wearing comfort and skin-friendliness, and thus improve the market competitiveness of the polyester fabric.

[0031] (2) The functional fibers prepared by the present invention use bamboo fibers as the matrix. On the one hand, bamboo fibers have a large number of pore structures and good hygroscopicity. During the preparation process, hydrophilic hydroxyl groups are generated, enhancing the hygroscopicity and skin-friendly property. They can cooperate with the modified composite polyester fibers to improve the hygroscopicity of the polyester fabric. At the same time, bamboo fibers have good strength and toughness, which play a positive role in the mechanical properties of the fabric. On the other hand, 2-mercaptopyridine-N-oxide is a safe, efficient antibacterial substance with a broad-spectrum antibacterial effect. By introducing 2-mercaptopyridine-N-oxide into bamboo fibers through chemical bonding, this firmly bonded method can ensure that the fabric still has excellent antibacterial properties after being washed multiple times during use, avoiding the shedding or precipitation of antibacterial substances during the washing process, resulting in a reduction in antibacterial performance, the erosion of the fabric by bacteria and other microorganisms, the generation of unpleasant odors due to bacterial growth on the fabric, an increase in cleaning difficulty, and a shortening of the service life of the fabric.

[0032] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following will briefly introduce the drawings required for the description of the embodiments. Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings.

[0034] Figure 1 It is the infrared spectrum diagram of the modified composite polyester fiber prepared by the present invention. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, rather than all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present invention.

[0036] The preparation methods of the modified composite polyester fibers and functional fibers in the following examples and comparative examples are as follows:

[0037] I. Preparation of Modified Composite Polyester Fibers

[0038] Step A: Add 3.2 g of polyester fibers to an acetone solution. After soaking for 16 h, wash and dry them with deionized water. Then put the dried polyester fibers into a plasma generator, evacuate first and then introduce oxygen for treatment for 80 s, adjust the pressure to 50 Pa, and the power to 45 W to obtain treated polyester fibers;

[0039] Step B: Add 3 g of treated polyester fibers into dimethyl sulfoxide. After stirring and mixing evenly, add 2 g of 3-chloropropyl isocyanate and 0.2 g of dibutyltin dilaurate. Raise the temperature to 65 °C and stir and react for 4 h. Then filter, wash, and dry to obtain modified polyester fibers.

[0040] Step C: Add 3 g of modified polyester fibers and 2.5 g of bacterial cellulose into N,N-dimethylformamide. After mixing evenly, add 1 g of triethylamine. Raise the temperature to 70 °C and react for 3 h. Then separate the product, wash, and dry to obtain modified composite polyester fibers.

[0041] Perform infrared testing on the modified composite polyester fibers. As Figure 1 shown, through analysis, an absorption peak of N-H appears at 3312 cm -1 ; an absorption peak of ester group C=O appears at 1734 cm -1 ; an absorption peak of C=O in carbamate appears at 1708 cm -1 ; an absorption peak of C-N appears at 1540 cm -1 ; an absorption peak of C-O-C appears at 1080 cm -1 ; and an absorption peak of glycosidic bond appears at 902 cm -1 .

[0042] II. Preparation of functional fibers

[0043] Step T1: Add 3.5 g of bamboo fibers into a potassium hydroxide solution with a mass fraction of 10%. After stirring evenly, raise the temperature to 45 °C and oscillate at 150 r / min for 1 h. Then wash, filter by suction, and dry to obtain pretreated bamboo fibers.

[0044] Step T2: Disperse 3.3 g of pretreated bamboo fibers in toluene solution to form a uniform suspension. Add 2 g of neopentyl glycol diglycidyl ether and 0.3 g of boron trifluoride diethyl etherate. After mixing evenly, raise the temperature to 65 °C and stir for 4 h. Then filter, wash, and dry to obtain modified bamboo fibers.

[0045] Step T3: Disperse 3 g of modified bamboo fibers in N,N-dimethylformamide to form a uniform suspension. Add 1.8 g of 2-mercaptopyridine-N-oxide and 0.2 g of tetrabutylammonium fluoride. After mixing evenly, raise the temperature to 45 °C and react for 5 h. Then filter by suction, wash, and dry to obtain functional fibers.

[0046] Weigh 0.5 g of bamboo fiber and 0.5 g of functional fiber, and use a Perkin-Elmer 2400 elemental analyzer to analyze their organic element content. From the test results, it can be seen that there is no sulfur element and nitrogen element in the bamboo fiber, while the sulfur element percentage content in the functional fiber is 8.21%, and the nitrogen element percentage content is 3.45%. It can be reasonably speculated that the bamboo fiber reacts with 2-mercaptopyridine-N-oxide, thereby providing sulfur element and nitrogen element.
