Description

Technical Field

[0001] The invention relates to the technical field of antistatic clothing fabric preparation, in particular to an antistatic clothing environmentally friendly fabric and a preparation method thereof. Background Art

[0002] Anti-static clothing is a special kind of work clothing, which is mainly used to prevent the generation and accumulation of static electricity. In some environments that are sensitive to static electricity, such as electronic manufacturing, biotechnology, precision instruments, etc., the generation of static electricity may cause damage to products, or even cause fires or explosions. Anti-static clothing can effectively release the static electricity generated by the human body to the ground through its special material and design, thus avoiding the harm of static electricity.

[0003] Anti-static clothing is usually made of special anti-static clean fabrics, in which conductive fibers are woven. As shown in an anti-static fabric and protective clothing with prior art publication number CN114055901A, the conductive fibers can quickly leak and disperse the generated static electricity to prevent local accumulation of static electricity. The working principle of anti-static clothing is to utilize the corona discharge and leakage discharge mechanism of conductive fibers to neutralize part of the ions generated by the friction of the operator with the charge of the work clothes fabric, and the other part of the ions are neutralized with the earth or the environment, thereby eliminating static electricity.

[0004] Since the conductive fiber itself has poor tensile strength, the conductive fiber in the antistatic fabric prepared by the above method is prone to breakage and derailment during daily wear and washing, which will affect the antistatic property of the fabric. In view of this problem, the prior art publication number CN113561587A proposes a method of twisting conductive metal fibers with polyester fibers in the form of short fibers into yarns for weaving antistatic fabrics. However, after friction, the fibers at the places with smaller twists are prone to loosening and protruding, and then form fluff and pilling, which affects the texture of the fabric. Summary of the invention

[0005] In view of the deficiencies in the prior art, the present invention provides an environmentally friendly antistatic clothing fabric and a preparation method thereof. The nano-copper particles mixed inside the antistatic composite fiber are used to prevent static electricity. At the same time, the antistatic composite fiber is a filament, and the prepared fabric is not easy to pilling, so as to ensure the quality of the fabric, and can effectively solve the problems in the background technology.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: an anti-static clothing environmentally friendly fabric, which is made of anti-static composite fiber and breathable fiber as raw materials and woven by a textile machine using twill;

[0007] The raw materials used in the antistatic composite fiber include, by weight percentage: 82%-90% of polyethylene terephthalate slices, 8%-14% of nano copper particles, 1%-2% of a catalyst, and 1%-2% of a stabilizer.

[0008] Preferably, the breathable fiber is spandex fiber.

[0009] Preferably, the catalyst used is antimony trioxide;

[0010] The stabilizer is selected from one of trimethyl phosphate, triphenyl phosphate and triphenyl phosphite.

[0011] The present invention also provides a method for preparing the above-mentioned antistatic clothing environmentally friendly fabric, comprising the following steps:

[0012] Step 1: Prepare the ingredients

[0013] S1. Preparation of nano copper particles: adding anhydrous copper chloride to a solvent containing a reducing agent, a dispersant and an antioxidant, heating to 100-200° C. while stirring, reacting for 30 to 200 minutes, cooling, washing, centrifuging and drying to obtain nano copper particles;

[0014] S2. Raw materials are prepared by weight: polyethylene terephthalate slices, nano copper particles, catalysts and stabilizers;

[0015] S3, placing polyethylene terephthalate slices and nano copper particles in a stirring tank, adding a catalyst and a stabilizer, and uniformly mixing the polyethylene terephthalate slices and the nano copper particles under high temperature and high pressure, while the mixture of the polyethylene terephthalate slices and the nano copper particles undergoes a polymerization reaction to form long-chain polyester molecules, thereby obtaining a polyester melt;

[0016] S4, the polymerized polyester melt is spun through a spinning machine, and the spinning machine extrude the polyester melt through tiny holes on a spinneret to form filaments;

[0017] S5, sending the filaments into a stretching device for stretching and shaping to form long and thin filaments;

[0018] S6, using a reel to wind up the filaments, keeping the filaments neat and tight during winding, to obtain an antistatic composite fiber;

[0019] Step 2: setting the fabric weaving form to twill weave on a textile machine, setting the warp to anti-static composite fiber and the weft to breathable fiber, and then obtaining the anti-static clothing environmentally friendly fabric after weaving, finishing, shaping and drying.

[0020] Preferably, in step S1, the concentration of anhydrous cupric chloride is 0.05-10 mol / L, the concentration of the dispersant is 10-80 g / L, the molar ratio of the reducing agent to anhydrous cupric chloride is 0.5:1-4:1, and the molar ratio of the antioxidant to anhydrous cupric chloride is 0.1:1-2:1.

[0021] Preferably, in step S1, the dispersant is selected from one of polyvinyl pyrrolidone, octadecylamine, and triethanolamine;

[0022] The reducing agent is selected from one of sodium phosphite, ascorbic acid and sodium borohydride;

[0023] The solvent is selected from one of diethylene glycol, ammonium hydroxide and ethylene glycol;

[0024] The antioxidant is selected from isopropyl alcohol or stearyl mercaptan.

[0025] Preferably, the polyethylene terephthalate slices used in step S2 are dried, mainly to remove moisture in the polyethylene terephthalate slices to prevent it from affecting the subsequent polymerization reaction.

[0026] Preferably, the stretching speed of the stretching device in step S5 is 600-1200 m / min, and the rotation speed of the reel in step S6 is 700-1000 r / min.

[0027] Compared with the prior art, the present invention provides an antistatic clothing environmentally friendly fabric and a preparation method thereof, which has the following beneficial effects:

[0028] 1. The present invention uniformly mixes polyethylene terephthalate slices with nano copper particles to make an engineering polyester melt, so that the antistatic composite fiber obtained by a spinning machine not only has the advantage of long length, so that the prepared fabric is not easy to pilling, but also can prevent static electricity by utilizing the nano copper particles mixed inside the antistatic composite fiber. At the same time, the antistatic composite fiber is also woven in a twill weave manner for the fabric. The surface of the fabric made of the twill weave is flat, which can avoid the pilling of the fabric to the greatest extent possible, thereby ensuring the quality of the fabric.

[0029] 2. By weaving spandex fiber with good elasticity and air permeability as the weft together with the antistatic composite fiber, the prepared fabric not only has the traditional antistatic performance, but also improves the elasticity and air permeability of the fabric, further improving the comfort of people when wearing it.
