Embodiment 1

[0040] Immerse the polyester fabric in 30% acrylic acid solution, then pass the fabric through squeeze rollers, and put the fabric with 50% liquid into the irradiation room protected by nitrogen gas. After four times of padding and irradiation, the irradiation dose reaches 100KGY, after irradiation, washed with water, the grafting rate of acrylic acid is 50%. The grafted fabric is padded in a solution of 40% NMDPPA and 6-hydroxymethyl tripolyphosphate (the weight ratio of the two monomers is 2:1), and the amount of liquid is 70%, and it is dried at 105 degrees. 5 minutes, bake at 180 degrees for 10 minutes, soap and wash. The limiting oxygen index of the obtained fabric is 28, and the burning does not drip, and the fabric is charred.

Embodiment 2

[0042] Immerse the polyester fabric in 50% acrylic acid solution, then pass the fabric through squeeze rollers, put the fabric with 50% liquid into the irradiation room protected by nitrogen, and pass through padding and irradiation twice to make the irradiation dose reach 100KGY, after irradiation, washed with water, the grafting rate of acrylic acid is 50%. The grafted fabric was padded in a solution of 40% NMDPPA and 6-hydroxymethyl tripolyphosphoric acid (the weight of the two monomers was 2: 1) with a concentration of 70%, and dried at 105°C for 5 Minutes, bake at 180 degrees for 10 minutes, soap and wash. The limiting oxygen index of the obtained fabric is 28, and the burning does not drip, and the fabric is charred.

Embodiment 3

[0044] Immerse the polyester fabric in 50% acrylic acid solution, then pass the fabric through squeeze rollers, put the fabric with 60% liquid into the irradiation room protected by nitrogen, and pass through 2 times of padding and irradiation to make the irradiation dose reach 120KGY, after irradiation, washed with water, the grafting rate of acrylic acid is 60%. The fabric after grafting is padding in the solution that concentration is 40% NMDPPA and 4 methylol glycoluril (the weight of two kinds of monomers is 4: 1), and the liquid amount is 70%, 105 ℃ dry 5 minutes, 180 Bake for 10 minutes, soap and wash. The limiting oxygen index of the obtained fabric is 28, and the burning does not drip, and the fabric is charred.

Abstract

The invention provides a preparation method of flame retarding and anti-droplet fiber or textile, and the flame retarding and anti-droplet fiber or textile prepared by utilizing the preparation method. In the preparation method of the invention, fiber or textile is padded and grafted with a monomer solution, and subsequently grafted by electron radiation; then, the fiber or the textile is padded with a cross linker solution and treated with baking so as to cause a fibre-forming polymer to form three-dimensional net type structure. Both of the monomer solution and the cross linker solution can contain flame-retarding elements, and at least one of the two contains the flame-retarding elements so as to lead the synthetic fibers or textiles to realize the dual effects of droplet resistance and flame-retarding. The method of the invention is characterized by strong adaptability to processed objects and good flame-retarding and anti-droplet performance, and the industrialization of the method of the invention is easy to be fulfilled.

Description

technical field [0001] Generally speaking, the present invention relates to synthetic fibers and fabrics thereof, more specifically, the present invention relates to a method for preparing fibers or fabrics with flame-retardant and anti-dripping properties and the flame-retardant and anti-dripping fibers or fabrics prepared according to the method . Background technique [0002] Due to the low limiting oxygen index of synthetic fibers, it is easy to burn, so the fires caused by the flammability of synthetic fibers have caused serious threats to the safety of people's lives and property every year. The flame retardant research of synthetic fibers has long been a global concern. Adding flame retardants to synthetic fibers to make them flame retardant is an effective way to solve the problem of synthetic fibers being flammable. Since the 1970s, a lot of work has been done on the research and development of flame-retardant synthetic fibers at home and abroad, and many of them ...
