Abstract

The invention relates to a preparation method of the easy dyeing flame-retardant non-woven fabric and belongs to the technical field of a building decoration material. Raw materials such as flame-retardant fibers are first processed through scraping, then scraps and the dye are mixed and stirred and then heated, through combination of the scraps, the dye and the raw materials are made to be more evenly mixed, products have good average performance, the products are evenly dyed and are not easy to fade, fire resistance is greatly improved, after extrusion and sizing of the products under the high temperature, the longitudinal and transverse tensile strength of the non-woven fabric is enhanced, and the non-woven fabric can be widely used in fire-fighting clothing, fire-fighting products, wall coverings and various veneer materials.

Example Embodiment

[0020] The present invention will be further explained below:
[0021] A processing technology of flame-retardant non-woven fabric is characterized in that it comprises the following steps:
[0022] (1) Put the flame-retardant fiber and polyester into the shredder for shredding;
[0023] (2) Put the dye in step 1 above;
[0024] (3) Heating is carried out, the heating temperature is 270℃;
[0025] (4) Mix and stir the raw materials and dyes of step 3 above;
[0026] (5) Heat the stirred mixture in step 4 and perform hot pressing;
[0027] (6) U-shaped PTC electric heater is used for drying treatment;
[0028] (7) Curling treatment;
[0029] (8) Sanding treatment;
[0030] (9) Cut and pack.
[0031] The average particle size of the scraps in step (1) is 5 mm.
[0032] In step (2), the dye is a mixture of Congo red and methyl blue.
[0033] The heat-pressing treatment temperature in step (5) is 250°C.
[0034] The temperature of the drying treatment in step (6) is 60° C., and the drying rate is 1.5 m/min.
[0035] The invention provides a method for preparing easy-dying flame-retardant non-woven fabrics. The raw materials such as flame-retardant fibers are first processed into scraps, and then the scraps and dyes are mixed and stirred for heating. This combination of scraps makes The dye and raw materials are mixed more evenly, the product performance is good, the product is evenly dyed and it is not easy to fade, the flame resistance performance has been greatly improved, the product has been subjected to high temperature shaping and extrusion to enhance the longitudinal and longitudinal tensile strength of the non-woven fabric. Widely used in fire-fighting clothing, fire-fighting supplies, wall coverings and various veneer materials
