Problems solved by technology

Although the ultrasonic wave has instantaneous cavitation and strengthens the penetration of the finishing agent on the fiber surface, the finishing agent can only be physically adsorbed on the fiber surface through various van der Waals forces, hydrogen bonds and other non-chemical bonds. Under the action of organic solvents, it is easily absorbed. Dissolution, and the production equipment is complex and the production cost is high
In addition, the non-woven fabric does not have flame retardancy, so it is not suitable for high temperature applications

preparation example Construction

[0027] A preparation process of antistatic flame retardant nonwoven fabric, the nonwoven fabric is PP nonwoven fabric, made of the following raw materials in parts by weight: 80-100 parts of polypropylene, 12-15 parts of maleic anhydride grafted polypropylene, 6-9 parts of reinforcing filler, 1-1.2 parts of flame retardant;

[0028] Reinforcing fillers are prepared by the following methods:

[0029] (1) Dissolving graphene oxide in an airtight container with xylene solution for 24 hours, and drying in an electric thermostat oven at 75°C to obtain pretreated graphene oxide;

[0030] (2) Dissolving dodecyl phosphate in 75% ethanol aqueous solution by volume fraction is prepared as a 10% modified solution by mass fraction;

[0031] (3) Add the pretreated graphene oxide to the modified solution according to the solid-to-liquid ratio of 1g: 20mL, first ultrasonic at room temperature for 10-12min, then raise the temperature to 60°C and stir for 180-200min, filter and dry to obtain ...

Abstract

The present invention discloses a preparation technology of an anti-static and flame-retardant non-woven fabric. The preparation technology comprises the following steps of 1, performing vacuum dryingon raw materials at 80 DEG C overnight, and putting the raw materials into a mixer for mixing; 2, putting a mixed material into a melt-blowing spinning machine for spinning the mixed material into apolypropylene non-woven fabric; and 3, preparing 1,4-butylene glycol, benzophenone and absolute ethanol into a solution, soaking the non-woven fabric in the solution, performing ultraviolet lamp irradiation, and performing cleaning. The non-woven fabric takes PP resin as a non-woven fabric base material, and by adding a reinforcing filler into the base material, the mechanical performance and theantistatic performance of the non-woven fabric are enhanced; by adding a flame retardant into the base material, a synthesized flame retardant not only has good compatibility with a PP base, but alsocan enable the non-woven fabric to achieve the excellent flame-retardant effect; and the reinforcing filler and the flame retardant are directly blended with the PP resin, are different from finishingof finishing liquid, difficultly fall and lose effect, and have durable antistatic performance and flame retardant performance.

Description

technical field [0001] The invention belongs to the field of functional fabrics, and in particular relates to a preparation process of an antistatic and flame retardant nonwoven fabric. Background technique [0002] Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then undergoes hydroentanglement, needle punching, or hot rolling reinforcement, and finally finishes finishing Formed non-woven fabric. A new type of fiber product with soft, breathable and planar structure, which has the advantages of not generating lint, strong, durable, silky soft, and has a cotton feeling. Ordinary non-woven fabrics do not have antistatic function. The surface resistance of the fiber is too large and the friction voltage is high. It is easy to generate static electricity during use, not only easy to absorb dust, but also not suitable for use in the processing of electronic products tha...
