Embodiment 1

[0016] Embodiment 1 A kind of preparation method of polyester flame-retardant non-woven fabric, comprises the following steps:

[0017] a. Preparation of impregnation solution: take 40-50 parts of flame retardant, 40-50 parts of ethyl acetate, and 10 parts of penetrant;

[0018] b. Impregnation: Immerse the polyester non-woven fabric in the impregnation solution, add a certain proportion of acetic acid, and control the pH of the system to 6~8;

[0019] c. Pretreatment: after dipping, squeeze by pressing rollers, and then dry at infrared temperature of 100~120℃ for 0.5~1 h;

[0020] d. Drying: After pretreatment, dry in an oven at 180-210°C for 0.5-2 hours;

[0021] e. Winding: After drying, the product polyester flame-retardant non-woven fabric is obtained by winding.

[0022] The flame retardant is one or more of triphosphate, FRC-1, decabromodiphenyl ether and hexabromocyclododecane.

[0023] The penetrating agent is one of JFC, JFC-1, JFC-2 and JFC-E.

Embodiment 2

[0024] Embodiment 2 A kind of preparation method of polyester flame-retardant non-woven fabric, comprises the following steps:

[0025] a. Preparation of impregnation solution: take 40 parts of flame retardant, 50 parts of ethyl acetate, and 10 parts of penetrant;

[0026] b. Impregnation: Immerse the polyester non-woven fabric in the impregnation solution, add a certain proportion of acetic acid, and control the pH of the system to 7;

[0027] c. Pretreatment: after dipping, squeeze by pressing rollers, and then dry at 120°C for 1 h in the infrared;

[0028] d. Drying: After pretreatment, dry in an oven at 210°C for 2 hours;

[0029] e. Winding: After drying, the product polyester flame-retardant non-woven fabric is obtained by winding.

[0030] The flame retardant is one or more of triphosphate, FRC-1, decabromodiphenyl ether and hexabromocyclododecane.

[0031] The penetrating agent is one of JFC, JFC-1, JFC-2 and JFC-E.

Embodiment 3

[0032] Embodiment 3 A kind of preparation method of polyester flame-retardant non-woven fabric, comprises the following steps:

[0033] a. Preparation of impregnation solution: take 45 parts of flame retardant, 45 parts of ethyl acetate, and 10 parts of penetrant;

[0034] b. Impregnation: Immerse the polyester non-woven fabric in the impregnation solution, add a certain proportion of acetic acid, and control the pH of the system to 6

[0035] c. Pretreatment: After dipping, squeeze by pressing rollers, and dry at 100°C for 1 h in the infrared;

[0036] d. Drying: After pretreatment, dry in an oven at 210°C for 1.5 h;

[0037] e. Winding: After drying, the product polyester flame-retardant non-woven fabric is obtained by winding.

[0038] The flame retardant is one or more of triphosphate, FRC-1, decabromodiphenyl ether and hexabromocyclododecane.

[0039] The penetrating agent is one of JFC, JFC-1, JFC-2 and JFC-E.

Abstract

The invention relates to a preparation method of a polyester flame-retardant non-woven fabric, and belongs to the technical field of textiles. A self-produced polyester filament non-woven fabric is used as a raw material; after unwinding and cleaning treatment, the polyester filament non-woven fabric enters a liquid storage tank containing a liquid flame retardant for dipping, is discharged and extruded by a pressing roller, is subjected to far-infrared preheating treatment, and then is dried by a drying oven and wound, and the polyester flame-retardant non-woven fabric is obtained. The methodhas the advantages that by adding a certain amount of penetrant, the flame-retardant effect is uniform; by adjusting the proportion of the flame retardant in the fabric surface, the problem of damp and greasiness of the fabric surface is solved; by controlling the pH of the system, the flame-retardant effect of the flame retardant is improved.

Description

technical field [0001] The invention relates to a preparation method of a polyester flame-retardant nonwoven fabric, which belongs to the technical field of textiles. Background technique [0002] As the most widely used polyester fiber, polyester has many excellent properties. The synthetic polyester non-woven fabric has a wide range of uses, such as industrial non-woven fabrics for dams and dams, filter cloths for chemical products, automotive air filter materials, and workshop air purification filter materials. [0003] In the prior art, there are few processes for obtaining flame-retardant non-woven fabrics by impregnation. [0004] How to make polyester non-woven fabrics have a better flame-retardant effect has become an urgent problem in the field of textile technology. Contents of the invention [0005] The purpose of the present invention is to overcome the above disadvantages and provide a preparation method of polyester flame-retardant non-woven fabric. [000...
