Description

Technical Field

[0001] The present invention relates to the technical field of polyester fabrics, and particularly to a production process of antistatic polyester fabrics. Background Art

[0002] With the continuous progress of modern textile technology, people's requirements for the functionality of textiles are also increasing day by day. Especially in the fields of electronics, medical care, protective clothing, etc., the demand for polyester fabrics with antistatic properties has increased significantly. Traditional polyester fabrics are prone to static electricity accumulation, which not only affects the wearing comfort but may also cause interference or damage to equipment. Therefore, it is particularly important to develop antistatic polyester fabrics.

[0003] In the prior art, the preparation of antistatic polyester fabrics is mainly achieved through two methods: one is through surface treatment technology, that is, coating or padding antistatic agents on the surface of polyester fabrics; the other is through blending modification technology, blending antistatic agents with polyester fibers to granulate and make antistatic fiber masterbatches, and then spinning them into fabrics.

[0004] Although the surface treatment technology is easy to operate, the adhesion firmness of the antistatic agent on the fabric surface is relatively low, and it is easy to fall off during washing or friction, resulting in poor durability of the antistatic performance. The blending modification technology can evenly disperse the antistatic agent in the polyester fiber matrix to form a firm bond, thereby improving the durability of the antistatic performance.

[0005] However, there are still some problems in the existing blending modification technology for preparing antistatic polyester fabrics. For example, the compatibility between the antistatic agent and polyester fibers is poor, and it is easy to agglomerate or precipitate during the spinning process, affecting the quality and performance of the fabric. In addition, the addition amount of the antistatic agent also needs to be strictly controlled, and too much or too little will affect the antistatic effect and physical properties of the fabric. Based on this, the present invention provides a production process of antistatic polyester fabrics. Summary of the Invention

[0006] The purpose of the present invention is to provide a production process of antistatic polyester fabrics, which improves the compatibility between the antistatic agent and polyester fibers and enhances the antistatic performance of polyester fabrics.

[0007] The present invention provides a production process of antistatic polyester fabrics, and the steps include: mixing nylon chips, an antistatic agent, plant fibers, and an antistatic auxiliary agent, extruding them into strips by a melt extruder, and cutting them into granular form to obtain antistatic fiber masterbatches; feeding the antistatic fiber masterbatches into a melt spinning machine for melt spinning, drawing and setting, and cooling and solidifying to obtain antistatic fibers, and then blending and weaving the antistatic fibers and cotton fibers to obtain the antistatic polyester fabric, and the weight of the fabric is 160 - 180 g / m 2 .

[0008] Further, the melting temperature in the melt extruder is 180 - 200 °C, and the rotational speed is 140 - 160 rpm.

[0009] Further, the weight ratio of the nylon chips, antistatic agent, plant fiber, and antistatic auxiliary is (70 - 80) : (6 - 8) : (14 - 16) : (2 - 3).

[0010] Further, the antistatic agent is a graphene / zinc oxide composite material with an average particle size of 40 - 100 nm.

[0011] Further, the preparation method of the graphene / zinc oxide composite material includes: grinding and mixing zinc acetate, reduced graphene oxide, and coupling agent for 40 - 60 min, then adding citric acid and continuing to grind and mix for 40 - 60 min, then heating at a rate of 10 °C / min, calcining at 420 - 460 °C for 60 - 80 min under a nitrogen atmosphere, and grinding after natural cooling to room temperature to obtain.

[0012] Further, the weight ratio of the zinc acetate, reduced graphene oxide, coupling agent, and citric acid is (1 - 2) : (4 - 5) : (0.06 - 0.1) : (1 - 2).

[0013] Further, the antistatic auxiliary is Tween - 80.

[0014] Further, the plant fiber includes wormwood fiber and mint fiber with a weight ratio of 1:2.

[0015] Further, the preparation method of the plant fiber includes: impregnating the plant fiber raw material, wormwood leaves or mint leaves, in a sodium hydroxide solution with a temperature of 50 - 60 °C and a mass fraction of 18 - 20% for 1 - 2 hours; taking out and rinsing with clear water until neutral, then impregnating in a hydrochloric acid solution with a mass fraction of 18 - 20% for 1 - 2 hours; taking out and rinsing with clear water until neutral, drying, and pulverizing through an 80 - mesh sieve to obtain.

[0016] Further, the weight ratio of the antistatic fiber and cotton fiber is (4 - 5) : (1 - 2).

[0017] The beneficial effects of the present invention are as follows: In the present invention, a graphene / zinc oxide composite material is selected as the antistatic agent, and this material has excellent electrical conductivity and chemical stability. The addition of graphene can significantly improve the electrical conductivity of the material, while zinc oxide can enhance the stability and dispersibility of the material. The uniform distribution of the graphene / zinc oxide composite material in the polyester fiber forms a conductive path, so that when the polyester fabric is affected by static electricity, the static charges can quickly be released into the air through the conductive path, thus avoiding static charge accumulation.

[0018] Among them, graphene is a two-dimensional carbon material, and its unique electronic structure endows it with extremely high electron mobility, making graphene an excellent conductive material. In the graphene / zinc oxide composite material, graphene serves as the core of the conductive network and can rapidly conduct static charges. Zinc oxide is a stable inorganic compound with good weather resistance and chemical stability. In the composite material, zinc oxide not only enhances the stability of the overall material but also serves as a carrier for graphene, helping graphene to be evenly dispersed in polyester fibers.

[0019] When the graphene / zinc oxide composite material is evenly introduced into polyester fibers, graphene nanosheets form a conductive network inside and between the fibers. These networks consist of countless tiny conductive channels that are interconnected and run through the entire fabric.

[0020] When the polyester fabric is subjected to static electricity, the static charges will rapidly spread in these conductive channels. Due to the high conductivity of graphene, the static charges can quickly transfer from one area of the fabric to another and are ultimately released into the air. This rapid charge transfer effectively prevents the accumulation of static charges on the fabric, thereby improving the antistatic performance of the fabric.

[0021] In this invention, Tween-80 is also used as a surfactant, which has good wetting and dispersing properties. Its addition can further improve the dispersibility of the antistatic agent in polyester fibers and enhance the compatibility between the antistatic agent and polyester fibers.

[0022] The addition of wormwood fibers and mint fibers in this invention not only increases the comfort and breathability of the fabric but also further enhances the antistatic performance of the fabric through their natural hygroscopicity and conductivity. These plant fibers form additional conductive channels in the fabric, helping to quickly release static charges.

[0023] Although the conductivity of wormwood fibers and mint fibers themselves may not be high, they have certain hygroscopicity and ion exchange capabilities. This means that they can help conduct static charges to a certain extent, thereby enhancing the conductivity of the entire fabric. When wormwood fibers and mint fibers are mixed with polyester fibers, they can form tiny conductive channels between the fibers. These channels can be interconnected with the conductive paths formed by the antistatic agent, thus forming a more perfect conductive network. This helps to dissipate static charges more quickly and improve the antistatic performance of the fabric.

[0024] In addition, the addition of plant fibers can further improve the compatibility between the antistatic agent and polyester fibers, and also further ensure the uniform dispersion of the graphene / zinc oxide composite material. Among them, wormwood fibers and mint fibers usually have good hydrophilicity, which means they can more easily absorb and retain moisture. When these plant fibers are mixed with polyester fibers, they can form a tiny wet layer at the fiber interface, which helps to improve the interfacial compatibility between the antistatic agent and polyester fibers. In addition, wormwood fibers and mint fibers contain polar groups such as hydroxyl groups and carboxyl groups, and these polar groups can interact with the polar parts in the antistatic agent, thereby enhancing the binding force between the antistatic agent and polyester fibers.
