Description

Technical Field

[0001] This invention relates to the field of textile fabric technology, specifically to an antistatic and antibacterial plush fabric and its preparation method. Background Technology

[0002] Traditional bedding, such as four-piece sets, is generally made of pure cotton fabric, which has advantages such as good warmth retention, softness, comfort, moisture absorption, and breathability. However, in cold winters, using pure cotton fabric requires the user to consume some of their own body heat to warm it up, which can lead to a cold experience. The development of plush fabrics has effectively solved this problem, offering softness, comfort, and good warmth retention, providing instant warmth against the skin. However, most current plush fabrics are made of 100% polyester (i.e., polyester fiber). Polyester fabric is prone to static electricity, especially in dry winters. Furthermore, polyester fabric has poor moisture absorption; if the user sweats, the sweat cannot escape from the body and surrounding environment, severely affecting comfort. In a humid and warm environment, bacteria can easily grow and multiply rapidly, posing potential health risks. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art by providing an antistatic and antibacterial plush fabric and its preparation method. The plush fabric prepared by this method is warm, soft and comfortable against the skin. After post-treatment, the plush fabric has good antibacterial properties, high antistatic ability and moisture absorption and breathability. While keeping warm, it can effectively prevent the growth of bacteria that may harm human health. It can be used to make winter bedding, pajamas and other intimate items, which are healthy and comfortable.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A method for preparing an antistatic and antibacterial plush fabric, characterized by comprising the following steps:

[0006] Step 1: Dissolve polyurethane biguanide powder and polythiophene powder separately in deionized water to obtain saturated aqueous solutions of polyurethane biguanide and polythiophene.

[0007] A saturated aqueous solution of polyurethane biguanide and a saturated aqueous solution of polythiophene were mixed to obtain a mixed aqueous solution with a pH of 6.0-8.0.

[0008] Water is removed from the mixed aqueous solution by vacuum evaporation to obtain a dry antistatic antibacterial agent;

[0009] Step 2: Melt-mix silane coupling agent KH560, polyvinyl alcohol, polyethylene terephthalate particles and antistatic antibacterial agent obtained in Step 1, and spin them to obtain antistatic antibacterial fiber.

[0010] Step 3: Spin the antistatic and antibacterial fibers into antistatic and antibacterial yarn;

[0011] Step 4: Spin the antistatic and antibacterial yarn into an antistatic and antibacterial fabric base.

[0012] Step 5: Perform surface napping treatment on the antistatic and antibacterial fabric greige to obtain antistatic and antibacterial plush fabric.

[0013] Preferably, the polythiophene molecule contains sulfonic acid groups;

[0014] The sulfonic acid group is selected from either polystyrene sulfonic acid or polyethylene sulfonic acid.

[0015] The preparation method of polythiophene refers to patent CN1239576C (polythiophene), and the molecular formula of the obtained polythiophene is (C... 24 H 32 O5S2)n, n=5-100.

[0016] Preferably, in step two, the silane coupling agent KH560, polyvinyl alcohol, polyethylene terephthalate particles and the antistatic antibacterial agent obtained in step one are first melt-mixed, extruded, cooled and granulated to obtain antistatic antibacterial resin particles; then the antistatic antibacterial resin particles are melted and spun to obtain antistatic antibacterial fibers.

[0017] Preferably, the saturated aqueous solution of polyaminopropyl biguanide and the saturated aqueous solution of polythiophene are prepared at 25°C.

[0018] Preferably, the reduced pressure evaporation is carried out at a temperature of 55-75°C and an absolute pressure of 5-100 kPa.

[0019] Preferably, the mass ratio of the antistatic antibacterial agent, polyvinyl alcohol, silane coupling agent KH560, and polyethylene terephthalate particles is 1-10:5-50:1-10:100-300.

[0020] Preferably, the polyvinyl alcohol comprises polyvinyl alcohol 1788.

[0021] Preferably, the antistatic and antibacterial fiber is a short fiber obtained by cutting a filament bundle spun through melt mixing and spinning process;

[0022] The length of the short fibers is 4-6mm.

[0023] Antistatic and antibacterial plush fabrics were prepared using the methods described above.

[0024] A method for preparing antistatic and antibacterial resin particles includes the following steps:

[0025] Step 1: Dissolve polyurethane biguanide powder and polythiophene powder separately in deionized water to obtain saturated aqueous solutions of polyurethane biguanide and polythiophene.

[0026] A saturated aqueous solution of polyurethane biguanide and a saturated aqueous solution of polythiophene were mixed to obtain a mixed aqueous solution with a pH of 6.0-8.0.

[0027] Water was removed from the mixed aqueous solution by vacuum evaporation to obtain an antistatic and antibacterial agent;

[0028] Step 2: Melt-mix, extrude, cool, and pelletize the silane coupling agent KH560, polyvinyl alcohol, polyethylene terephthalate granules, and the antistatic and antibacterial agent obtained in Step 1 to obtain antistatic and antibacterial resin granules.

[0029] The beneficial effects of this invention are as follows:

[0030] The fabric of this invention is made from polyethylene terephthalate (PET) as the main raw material, with the addition of silane coupling agent KH560, polyvinyl alcohol (PVA), and antistatic and antibacterial agents to produce antistatic and antibacterial fibers. It exhibits good wrinkle resistance and shape retention, durability, and excellent antistatic and antibacterial effects. The antistatic and antibacterial agent overcomes the problem of static electricity generation in polyester fibers and imparts antibacterial capabilities, preventing static electricity during use and ensuring good antibacterial properties, making it safe and comfortable even when worn close to the skin. The introduction of PVA improves the poor hydrophilicity of pure polyester fibers, effectively enhancing the fabric's absorbency and breathability, improving user comfort while preventing bacteria from creating a suitable environment for survival and reproduction. The addition of silane coupling agent KH560 improves the compatibility between PET and PVA, enhancing the stability of the fiber material's performance.

[0031] The antistatic and antibacterial agent of this invention is prepared from a water-soluble conductive polymer, polythiophene, and a water-soluble organic antibacterial agent, polyaminopropyl biguanide. The polythiophene molecule contains sulfonic acid groups, which makes the polythiophene water-soluble and acidic, and its aqueous solution is acidic. The aqueous solution of polyaminopropyl biguanide is alkaline. The aqueous solutions of the two polymers are subjected to an acid-base neutralization reaction until the reaction system is neutral or close to neutral, and a stable sulfonate guanidine salt compound is obtained. When it is melt-mixed with polyethylene terephthalate, polyvinyl alcohol, etc., the high-temperature melting will not destroy the molecular structure. Under the action of silane coupling agent KH560, it can achieve good dispersion and compatibility with polyethylene terephthalate and polyvinyl alcohol, thereby improving the uniformity and stability of the antistatic and antibacterial effect of the fiber.

[0032] The sulfonic acid groups in the polythiophene molecular chain have a strong wetting and dispersing effect, which can improve the hydrophilicity of the fiber and further improve the absorbency and breathability of the fabric; in addition, the long alkyl chain in the molecule has good flexibility, which can improve the softness of pure polyester fiber, and the resulting fabric is soft and skin-friendly.
