Description

Technical Field

[0001] This invention relates to the field of microfiber cleaning cloth technology, specifically to a microfiber dust removal cleaning cloth with electrostatic adsorption function and its preparation method. Background Technology

[0002] As people's demands for a cleaner living environment increase, the need for dust removal and cleaning tools is growing. Traditional cleaning cloths mostly rely on physical friction or moisture adsorption to remove dust, but their effectiveness in adsorbing fine impurities such as dust and hair is limited. Microfibers, due to their small fiber size and large specific surface area, have good cleaning potential, but their electrostatic adsorption capacity is limited, making it difficult to retain fine dust for a long time.

[0003] A search revealed a cleaning wipe made from microfiber nonwoven fabric scraps and its preparation method, with publication number CN109532164B. This invention has a soft feel, good wiping performance, strong tear resistance, and can be used multiple times. At the same time, it reduces the waste of raw materials in the microfiber nonwoven fabric production process and lowers the production cost of enterprises.

[0004] This invention uses scrap materials to prepare wiping cloths. The shape and size of the wiping cloths are not easy to control, and the coating effect is easily inconsistent due to the different cloth pieces during mass production. This results in some wiping cloths having poor actual cleaning ability. At the same time, some electrostatic cleaning cloths on the market use post-treatment coating to impart electrostatic properties, but there are problems such as easy coating peeling, poor washability, and hardening of the hand feel. Summary of the Invention

[0007] Microfiber substrate, electrostatic reinforcing agent coating, and electrostatic adsorption polarization layer.

[0008] Optionally, the method for preparing the microfiber dust removal cleaning cloth with electrostatic adsorption function includes:

[0010] S2. Immerse the microfiber substrate in a treatment solution containing an electrostatic reinforcing agent and oscillate at a constant temperature of 60°C for 30 minutes.

[0011] S3. After removal, the surface of the microfiber substrate is formed by hot air shaping to form an electrostatic reinforcing agent coating. Then, surface polarization treatment is performed to obtain an electrostatic adsorption polarization layer on the polarized surface, thus obtaining a microfiber dust removal and cleaning cloth with a long-lasting electrostatic adsorption function.

[0012] Optionally, the conductive polymer masterbatch in S1 is a fluorine-containing silicon electret masterbatch.

[0013] Optionally, the fineness of the single filament of the ultrafine fiber substrate in S1 is 0.8-1.2 dtex.

[0015] Optionally, the hot air setting temperature in S3 is 120-140℃ and the time is 10-15min, which is lower than the melting temperature of the quaternary ammonium salt surfactant and polyelectrolyte complex.

[0016] Optionally, the surface polarization treatment in S3 adopts a corona discharge method with a voltage of 8-12kV and a treatment time of 5-10s.

[0017] Optionally, the cleaning cloth is suitable for cleaning micro-dust on surfaces such as home furnishings, vehicles, and electronic device screens, and the cleaning cloth can be washed and reused in water below the boiling point.

[0025] Please see Figure 1 The present invention provides a technical solution: a microfiber dust removal and cleaning cloth with electrostatic adsorption function, comprising: microfiber substrate 1, electrostatic enhancer coating 2 and electrostatic adsorption polarization layer 3.

[0026] The preparation method of this microfiber dust removal cleaning cloth with electrostatic adsorption function is as follows:

[0027] S1. Polyester, nylon and fluorine-silicon electret masterbatch are mixed at a mass ratio of 70:25:5 and ultrafine fiber substrate 1 with a single filament fineness of 0.8-1.2 dtex is prepared by melt spinning equipment. The melt spinning process parameters are: spinning temperature 250-270℃, winding speed 2000-2500m / min, and spinneret orifice number 48-72.

[0028] S2. Immerse the microfiber substrate 1 in a treatment solution containing an electrostatic enhancing agent and oscillate at 60°C for 30 minutes. The electrostatic enhancing treatment solution comprises: 3-5 wt% dodecyltrimethylammonium chloride, 1-2 wt% sodium polyacrylate, and the remainder deionized water. Adjust the pH of the treatment solution to 7.5-8.5.

[0029] S3. Take out the treated microfiber substrate 1 and place it in a 130℃ hot air setting machine for 12 minutes to stabilize the fiber morphology and initially fix the electrostatic reinforcing agent coating 2. Then, perform surface polarization treatment and 10kV corona discharge polarization treatment for 8 seconds to form a persistent electrostatic field on the fiber surface, thus obtaining a microfiber dust removal and cleaning cloth with electrostatic adsorption function. The distance between the corona treatment electrodes is 5-8mm, and the relative humidity of the treatment environment is controlled at 40-60%.

[0030] In summary, this microfiber dust removal cleaning cloth with electrostatic adsorption function is made by blending polyester, nylon, and fluorine-silicon electret masterbatch to form a microfiber substrate 1, giving the fibers the ability to store basic charges. It is then impregnated with a quaternary ammonium salt-polyelectrolyte composite solution to construct an electrostatic reinforcing agent coating 2 on the fiber surface. Finally, charges are injected and captured on the fiber surface through corona polarization to form an electrostatic adsorption polarization layer 3. The cleaning cloth utilizes the microfiber structure to increase the specific surface area and contact opportunities with dust particles, and relies on the surface electrostatic field to adsorb dissimilarly charged or neutral microparticles, achieving efficient dust removal. This cloth is washable and reusable, has a high electrostatic performance retention rate, and is suitable for cleaning in various scenarios such as homes, vehicles, and electronic screens. The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
