The method comprises the following steps: after aramid fiber, hydrophobic conductive fiber and polyethylene composite fiber are compounded, the yarn is prepared into roving through opening, carding and two-step drawing; and then the roving is prepared into yarn through a ring spinning frame; and the yarn is transferred into a hot blast furnace and kept at 140-150 DEG C for 2-3 min to obtain the wear-resistant conductive yarn.

Description

Technical Field

[0001] This invention belongs to the field of conductive yarn technology, and specifically relates to a method for preparing abrasion-resistant conductive yarn. Background Technology

[0002] Conductive gloves are a type of safety equipment primarily used to prevent static electricity from harming the human body; hence, they are also called antistatic gloves. Conductive gloves possess excellent elasticity and antistatic properties, not only isolating products from damage caused by static electricity generated by the human body but also preventing harm to the user. Therefore, antistatic gloves are widely used in the electronics industry, semiconductor industry, cleanrooms, hospitals, and other fields. Furthermore, touchscreen gloves are also a type of conductive glove, enabling touchscreen functionality. Like antistatic gloves, both are woven from conductive yarns. Conductive yarns are functional fibers with conductive properties, produced by blending, interlacing, twisting, and networking conductive fibers with conventional textile fibers. Currently, the most popular conductive yarns are silver-plated conductive yarn and carbon nanotube conductive yarn.

[0003] Because the properties of single yarns made of different materials are different, different tensions need to be set when twisting composite yarns. If the required tensions are not properly controlled, bubbling and looping will occur on the finished composite yarn, resulting in yarn breakage and a decrease in the wear resistance of the final product. Summary of the Invention

[0004] The purpose of this invention is to provide a method for preparing abrasion-resistant conductive yarn, thereby solving the problem of poor abrasion resistance in existing conductive yarns.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A method for preparing abrasion-resistant conductive yarn includes the following steps:

[0007] Step 1: Vacuum dry the perfluoroethylene propylene copolymer and carbon nanotubes at 110±5℃, then transfer them to a mixer and add silane coupling agent KH560. Mix at 250-260℃ for 20-30 min, then transfer them to a twin-screw extruder equipped with a spinneret and spin them at 275℃. Stretch the extruded fibers 250% at 40-50℃ and a speed of 60 mm / min, then heat set to a fixed length at 180±5℃ for 8-10 min to obtain hydrophobic conductive fibers.

[0008] Furthermore, the ratio of perfluoroethylene propylene copolymer, carbon nanotubes and silane coupling agent KH560 is 9g:0.8-1g:0.04-0.05g.

[0009] Step 2: Vacuum dry high-density polyethylene and wear-resistant conductive particles at 110±5℃, then transfer them to a mixer and mix them at 125-130℃ for 20-30 minutes. Transfer them to a twin-screw extruder equipped with a spinneret and spin them at 230℃. Stretch the extruded fibers by 300% at 40-50℃ and a speed of 60mm / min. Heat set to a fixed length at 135±5℃ for 4-6 minutes to obtain polyethylene composite fibers.

[0010] Furthermore, the ratio of high-density polyethylene to wear-resistant conductive particles is 18g:1g.

[0011] Step 3: Mix aramid fiber, hydrophobic conductive fiber and polyethylene composite fiber in a mass ratio of 4-6g: 5-7g: 6-10g, then open and comb the fibers to make the different fibers have the same direction. Then, prepare roving by drawing the roving in two steps, and then prepare fine yarn by ring spinning machine.

[0012] Furthermore, the two-step drawing process includes first-stage drawing and second-stage drawing. The first-stage drawing has a draft ratio of 2.5-2.8 times in the front zone and 1.6-1.8 times in the back zone. The second-stage drawing has a draft ratio of 4.5-5 times in the front zone and 1.05-1.1 times in the back zone.

[0013] Step 4: Transfer the fine yarn to a hot air furnace and keep it at 140-150℃ for 2-3 minutes to obtain wear-resistant conductive yarn.

[0014] Furthermore, the wear-resistant conductive particles are prepared through the following steps:

[0015] Step 1: Add nano-sized graphene, micron-sized silicon carbide, deionized water, and dispersant to a mixing tank and stir at 500-1000 r / min for 20-40 min. Then transfer the mixture to a ball mill jar, add stabilizer and binder, and ball mill at 300-500 r / min for 3-4 h. Filter the mixture to obtain a slurry with a solid content of 65-70%. Spray-dry the slurry using a centrifugal spray dryer to obtain graphene-coated silicon carbide particles with a particle size of 50±10 μm.

[0016] The operating parameters of the centrifugal spray dryer are: centrifugal speed 230-240Hz, feed rate 10-12rpm, inlet air temperature 200±0.5℃, and outlet air temperature 120±0.5℃.

[0017] Furthermore, the ratio of nanoscale graphene, micron-scale silicon carbide, deionized water, dispersant, stabilizer and binder is 5g:15g:40-60mL:0.08g:0.1g:1.2-1.6g.

[0018] Furthermore, the dispersant is either tetramethylammonium hydroxide or hexadecyltrimethylammonium bromide.

[0019] Furthermore, the stabilizer is one or a mixture of two of n-heptanol and n-octanol in any ratio.

[0020] Furthermore, the adhesive is polyvinyl alcohol.

[0021] Step 2: Graphene-coated silicon carbide particles are loaded into a crucible and then transferred to a tube furnace at 100°C. Under nitrogen protection, the temperature is increased to 500°C at a rate of 5°C / min and held for 60-80 minutes. After natural cooling and degreasing, the material is discharged to obtain wear-resistant conductive particles.

[0022] The beneficial effects of this invention are:

[0023] This invention relates to a wear-resistant conductive yarn made by twisting aramid fibers, hydrophobic conductive fibers, and polyethylene composite fibers. The aramid fibers possess softness, heat resistance, and good mechanical properties. The hydrophobic conductive fibers are based on perfluoroethylene-propylene copolymer, which has good wear resistance, chemical resistance, and thermal stability, and is also hydrophobic, resulting in fibers with good water resistance. Carbon nanotubes help increase conductivity. Wear-resistant conductive particles are added to the polyethylene composite fibers. Under the temperature control of a hot air furnace, the polyethylene composite fibers melt, increasing their adhesion to other fibers. The contact between the wear-resistant conductive particles and the hydrophobic conductive fibers further enhances the conductivity of the wear-resistant conductive yarn.

[0024] A slurry was prepared using nanoscale graphene and micron-sized silicon carbide. Nanoscale graphene possesses excellent electrical conductivity, while micron-sized silicon carbide is a semiconductor material with corrosion resistance and wear resistance. A dispersant helps to evenly disperse both particles, while a stabilizer stabilizes the slurry and prevents particle deposition. A binder helps the nanoscale graphene adhere to the surface of the micron-sized silicon carbide. The faster the centrifugal spray dryer's rotation speed, the smaller the spray-dried particle size. Centrifugal spray drying facilitates control of the particle size of the graphene-coated silicon carbide particles. After degreasing to remove the binder, wear-resistant conductive particles are obtained. These particles help improve the wear resistance of wear-resistant conductive yarns. Micron-sized silicon carbide is a non-polar material; the polar wear-resistant conductive particles coated with nanoscale graphene have better compatibility and a tighter bond with polar high-density polyethylene, further enhancing its abrasion resistance.

[0057] Performance tests were conducted on Examples 4-6 and Comparative Examples 1-4. A precision resistance tester was used to measure the resistance of different conductive yarns at 1m lengths. Each group was repeated 5 times, and the average value R0 was taken. Then, 5 conductive yarns of 1m length from each group were placed in a mesh bag and washed in a washing machine for 2 hours. The average resistance R1 was measured again, and the resistance change rate after washing was calculated as ((average resistance before washing R0 - average resistance after washing R1) / average resistance before washing R0 × 100%) to evaluate its wash fastness. The breaking strength of different conductive yarns was tested according to GB / T 3916-2013 using a YG021 HL chemical fiber filament tensile testing machine. The clamping length of the conductive yarn sample was 250mm, and the clamping speed was 250mm / min. According to ASTM D... 3108-2001 tested the coefficient of friction of different conductive yarns. The test angle was 180°, the test speed was 100 mm / min, and the test time was 15 s. Each group was repeated three times, and the average value was taken. Five 1.5 m long conductive yarns were used in each group, with 25 cm left at each end for clamping. The yarns were fixed on the abrasion tester, and a 5 g weight was set. A 1 m section between the clamping parts was rubbed 20 times. After rubbing, the resistance R2 of the 1 m section of different conductive yarns was measured again, and the rate of change of abrasion fastness was calculated as ((average resistance before friction R0 - average resistance after friction R2) / average resistance before friction R0 × 100%). The results are shown in Table 1.
