Problems solved by technology

[0003] As the most commonly used synthetic fabric in daily life, polyester has good physical properties and anti-corrosion properties, but due to the large number of covalent bonds between its molecules, it is easy to generate and accumulate charges, and its hydrophobicity is large, and the charges dissipate Difficult, it is inevitable to generate static electricity. Polyester is made of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation reactions. The obtained fiber-forming polymer does not contain flame-retardant components in its structure, so polyester does not have flame-retardant properties
[0004] The existing preparation method of antistatic and flame retardant nonwoven fabric is generally to produce non-functional nonwoven fabric first, and then add the nonwoven fabric to the finishing solution with flame retardant and antistatic agent for impregnation. In this way, non-woven fabrics with flame retardant and antistatic properties are obtained. However, although this external flame retardant and antistatic agent are suitable for a variety of polymers, their effectiveness is only temporary. It is easy to lose by friction with other things

Abstract

The invention discloses a preparation method of an antistatic flame-retardant non-woven fabric for textiles. Polyethylene glycol terephthalate particles and an antistatic flame retardant are taken asraw materials for melting extrusion and enter a spinning assembly through a metering pump, then thin flow is extruded from a spinning nozzle, drafting and cooling are carried out to form fibers, the fibers form a net through a net forming device, the net forming fibers are conveyed to a hot rolling mill for hot rolling to form the antistatic flame-retardant non-woven fabric. A mode of melting theantistatic flame-retardant non-woven fabric and the polyethylene glycol terephthalate particles replaces an existing impregnating method, the prepared antistatic flame-retardant non-woven fabric has good flame-retardant and antistatic properties, can continuously maintain the antistatic and flame-retardant properties and has stronger washability, and the service life of the antistatic flame-retardant non-woven fabric is prolonged.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabrics, and in particular relates to a preparation method of an antistatic flame-retardant non-woven fabric for textile use. Background technique [0002] According to the composition of non-woven fabrics, there are polyester, polypropylene, nylon, spandex, acrylic, etc.; different components will have completely different styles of non-woven fabrics. [0003] As the most commonly used synthetic fabric in daily life, polyester has good physical properties and anti-corrosion properties, but due to the existence of a large number of covalent bonds between its molecules, it is easy to generate and accumulate charges, and its hydrophobicity is large and the charge escapes. Difficult, unavoidable to generate static electricity, polyester is made of purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensa...
