Problems solved by technology

[0003] However, anti-fouling is particularly important when working under the sea or diving for a long time. Microorganisms and bacteria in seawater can affect the diving suit, ranging from affecting the service life of the diving suit to breaking the diving suit during diving. , causing harm to divers; therefore, the present invention researches and prepares a long-acting antifouling fabric suitable for preparing diving suits, with better tear resistance and long service life.

Embodiment 1

[0031](1) The preparation method of carboxymethyl-cyclodextrin is: mix cyclodextrin, sodium hydroxide and deionized water in a mass ratio of 4.2:3.5:18, stir until dissolved, and add chlorine with 1.8 times the mass of cyclodextrin. Sodium acetate was stirred at 30 rpm for 3 hours, cooled to room temperature, adjusted to pH 4.8 with hydrochloric acid, and precipitated by adding methanol with 5 times the mass of cyclodextrin, filtered after precipitation, and dried in a vacuum drying oven at 80 °C Constant weight to obtain carboxymethyl-cyclodextrin;

[0032] (2) Disperse carboxymethyl-cyclodextrin in deionized water with 8 times the mass of carboxymethyl-cyclodextrin, and dropwise add 0.1 mass of carboxymethyl-cyclodextrin at a rate of 3 ml / min at 10 rpm times the mass fraction of 3-5% sodium hydroxide solution, continue to stir and dropwise add 0.45 times the mass of carboxymethyl-cyclodextrin with a mass fraction of 10% p-toluenesulfonyl chloride at a rate of 3-5ml / min. The...

Embodiment 2

[0038] (1) The preparation method of carboxymethyl-cyclodextrin is: mix cyclodextrin, sodium hydroxide and deionized water in a mass ratio of 4.4:3.5:19, stir until dissolved, and add chlorine with 1.9 times the mass of cyclodextrin. Sodium acetate was stirred and reacted at 40 rpm for 4 h, cooled to room temperature, adjusted to pH 4.9 with hydrochloric acid, and precipitated by adding methanol with 6 times the mass of cyclodextrin, filtered after precipitation, and dried in a vacuum drying oven at 85 °C Constant weight to obtain carboxymethyl-cyclodextrin;

[0039] (2) Disperse carboxymethyl-cyclodextrin in deionized water with 9 times the mass of carboxymethyl-cyclodextrin, and at 15 rpm, dropwise add 0.13 carboxymethyl-cyclodextrin mass at a rate of 4 ml / min times the sodium hydroxide solution with a mass fraction of 4%, continue to stir and dropwise add 0.48 times the mass of carboxymethyl-cyclodextrin with a mass fraction of 15% of the acetonitrile solution of p-toluenes...

Embodiment 3

[0045] (1) The preparation method of carboxymethyl-cyclodextrin is as follows: mix cyclodextrin, sodium hydroxide and deionized water in a mass ratio of 4.5:3.6:20, stir until dissolved, and add chlorine with twice the mass of cyclodextrin. Sodium acetate was stirred at 50 rpm for 5 h, cooled to room temperature, adjusted to pH 5 with hydrochloric acid, and precipitated by adding methanol with 8 times the mass of cyclodextrin, filtered after precipitation, and dried in a 90°C vacuum drying oven until Constant weight to prepare carboxymethyl-cyclodextrin

[0046] (2) Disperse carboxymethyl-cyclodextrin in deionized water with 10 times the mass of carboxymethyl-cyclodextrin, and dropwise add carboxymethyl-cyclodextrin at a rate of 5 ml / min at 10-20 rpm 0.15 times the mass of sodium hydroxide solution with a mass fraction of 5%, continue to stir and dropwise add 0.5 times the mass of carboxymethyl-cyclodextrin with a mass fraction of 20% acetonitrile solution of p-toluenesulfonyl...

Abstract

The invention discloses a long-acting anti-fouling fabric and a preparation method thereof, and relates to the technical field of fabrics. The long-acting anti-fouling fabric prepared by the invention sequentially comprises the Lycra cloth, the foamed rubber and the anti-fouling film from inside to outside; the anti-fouling film is prepared by reacting hyperbranched polyglycidyl ether with modified cyclodextrin; the modified cyclodextrin is prepared by grafting a hydroxylamine polymer to sulfydryl-carboxymethyl-cyclodextrin, so that the stability is enhanced, a large number of hydroxyl groups are introduced, the hydrophilicity is enhanced, the fabric has stain resistance, the density of a stain-resistant film is also enhanced, and the tear resistance of the fabric is further enhanced; the foaming rubber is prepared by blending chloroprene rubber, polyurethane rubber and fluoropolyether nitrile, vulcanizing and foaming; after the polyurethane rubber is added and blended, the vulcanization speed is increased, the tear resistance of the foaming rubber is improved, the Lycra cloth, the foaming rubber and the anti-fouling film are tightly connected, the peel strength of the fabric is enhanced, and the service life of the fabric is prolonged.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a long-acting antifouling fabric and a preparation method thereof. Background technique [0002] The original intention of diving is to go below the surface of the water with or without professional tools for operations such as underwater surveys, salvage, repairs and underwater engineering. Post diving has gradually developed into a leisure sport with the main content of underwater activities, so as to achieve the purpose of physical exercise and leisure and entertainment, which is widely loved by the public. Diving clothing is a must for diving, it can be used to prevent the rapid loss of body temperature during diving, resulting in hypothermia, and also to protect the diver from reefs or harmful animals and plants. [0003] However, when working or diving underwater for a long time, anti-fouling is particularly important. Microorganisms and bacteria in seawater can affect the...
