Examples
Embodiment 1
[0033] Mix 100g of polyester resin with 1g of sodium iodide, then add 2g of hydroxyethyl cellulose and 12g of 2,6-bis(4-aminophenoxy)benzonitrile, mix, then add 14g of silicon dioxide, 4g of fluorinated Ytterbium, mixed uniformly to obtain a polyester composition; then the polyester composition is added to a screw extruder to prepare polyester particles; then the polyester particles are prepared into polyester fibers by melt blown spinning; then the polyester Put the fiber into the finishing agent aqueous solution and soak for 60 seconds; then treat it at 140°C for 70 seconds to obtain water-treated fiber; then weave at a weaving speed of 3m / min to obtain water-treated sponge material; it is a rectangular parallelepiped structure with a thickness of 7mm. The density is 480 g / l.
[0034] The molecular weight of the polyester resin is 25,000-40,000; the finishing agent is composed of 13g of isooctyl acrylate, 10g of acrylamide, and 1.8g of benzoyl peroxide.
Embodiment 2
[0036] Mix 100g polyester resin with 1.2g sodium iodide, then add 2.6g hydroxyethyl cellulose and 15g 2,6-bis(4-aminophenoxy)benzonitrile, mix, then add 18g silicon dioxide, 7g Ytterbium fluoride, mixed uniformly to obtain a polyester composition; then the polyester composition was added into a screw extruder to prepare polyester particles; the polyester particles were prepared into polyester fibers by melt blown spinning; and then Put the polyester fiber into the finishing agent aqueous solution and soak for 60 seconds; then treat it at 140°C for 70 seconds to obtain water-treated fibers; then weave at a weaving speed of 3m / min to obtain water-treated sponge materials; it is a rectangular parallelepiped structure with a thickness of 7 mm with a density of 480 g / l.
[0037] The molecular weight of the polyester resin is 25,000-40,000; the finishing agent is composed of 13g of isooctyl acrylate, 10g of acrylamide, and 1.8g of benzoyl peroxide.
Embodiment 3
[0039] Mix 100g of polyester resin with 1g of sodium iodide, then add 2g of hydroxyethyl cellulose and 12g of 2,6-bis(4-aminophenoxy)benzonitrile, mix, then add 14g of silicon dioxide, 4g of fluorinated Ytterbium, mixed uniformly to obtain a polyester composition; then the polyester composition is added to a screw extruder to prepare polyester particles; then the polyester particles are prepared into polyester fibers by melt blown spinning; then the polyester Put the fiber into the finishing agent aqueous solution and soak for 60 seconds; then treat it at 140°C for 70 seconds to obtain water-treated fiber; then weave at a weaving speed of 3m / min to obtain water-treated sponge material; it is a rectangular parallelepiped structure with a thickness of 7mm. The density is 480 g / l.
[0040] The molecular weight of the polyester resin is 25,000-40,000; the finishing agent is composed of 16g of isooctyl acrylate, 10g of acrylamide, and 3.2g of benzoyl peroxide.
