Embodiment 1

[0040] The fabric (wherein the degree of acetalization of vinylon is 10%) made of 85% by weight of cotton fiber and 15% by weight of modified vinylon, enters the padding machine after low-temperature cleaning and dyeing, in 220g / l concentration of tetramethylol Add 2g / l penetrating agent JFC and 20g / l softener XL-300 in aqueous solution of phosphorous chloride, and carry out two-dipping and two-rolling processing, so that the flame-retardant working solution can penetrate into the amorphous area of ​​the fiber and tetramethylol chloride Phosphorus reacts chemically with the hydroxyl group of the modified vinylon, and maintains a liquid carrying amount of 90% by weight; dries at a temperature of 80°C to a moisture content of 18% by weight, and then proceeds under the condition of an ammonia gas flow rate of 750 liters / minute Ammonia fumigation at 90°C for 10 minutes, then enter the oxidation solution tank of 27% hydrogen peroxide 3g / l and sodium hydroxide 3g / l for oxidation reac...

Embodiment 2

[0042] The fabric made of 80% by weight of long-staple cotton fiber and 20% by weight of high-strength vinylon (vinylon acetalization degree is 60%), after low-temperature cleaning and dyeing, enters the padder, and the tetrahydroxyl at 260g / l concentration Add 2g / l penetrating agent JFC and 10g / l softener XL-300 in the aqueous solution of methylphosphorous chloride, and carry out two dipping and two rolling processes, so that the flame retardant working fluid can penetrate into the amorphous area of ​​the fiber and tetrahydroxymethyl chloride Phosphorus chemically reacts with the hydroxyl group of high-strength vinylon, and maintains the liquid volume within 90% by weight; dries to a moisture content of 18% by weight at a temperature of 85°C, and then under the condition that the flow rate of ammonia gas is 650 liters / minute Ammonia fumigation at 90°C for 12 minutes, then into an oxidation solution tank of 27% hydrogen peroxide 15g / l and sodium hydroxide 18g / l for oxidation re...

Embodiment 3

[0044] The fabric (wherein the vinylon acetalization degree is 62%) made of 82% by weight of cotton fiber and 18% by weight of ordinary vinylon blended, enters the padding machine after low-temperature cleaning and dyeing, in the tetramethylol of 200g / l concentration Add 2.2g / l penetrating agent JFC and 12g / l softener XL-300 to the phosphorus sulfate aqueous solution, and carry out two-dipping and two-rolling processing, so that the flame-retardant working fluid can penetrate into the amorphous area of ​​the fiber and tetrakishydroxymethyl phosphorus chloride Chemically react with the hydroxyl group of ordinary vinylon, and keep the amount of liquid in the range of 85% by weight; dry at a temperature of 88°C to a moisture content of 16% by weight, and then carry out under the condition of an ammonia gas flow rate of 600 liters / minute Ammonia fumigation at 90°C for 12 minutes, then enter the oxidation solution tank of 27% hydrogen peroxide 12g / l and sodium hydroxide 10g / l for ox...

Abstract

The invention relates to flame-retardant and anti-bacterial fabric for bed sheets and quilt covers in hotels and a preparation method of the fame-retardant and anti-bacterial fabric. The method comprises the following steps: a) providing and blending cotton fibers and unmodified or modified vinylon to obtain fabric; b) preparing an aqueous solution of a tetrakis(hydroxymethyl)phosphonium compound;c) soaking the fabric obtained in the step a) in the aqueous solution of the tetrakis(hydroxymethyl)phosphonium compound to obtain soaked fabric; d) drying the soaked fabric obtained in the step c) to obtain dried fabric; e) fumigating the dried fabric obtained in the step d) with ammonia to obtain ammonia fumigated fabric; f) oxidizing the ammonia fumigated fabric obtained in the step e), wherein in an ammonia fumigating process of the step e), applying insufficient amount of ammonia gas relative to the tetrakis(hydroxymethyl)phosphonium compound applied in the step c) to enable part of thetetrakis(hydroxymethyl)phosphonium compound in the fabric not to react with ammonia gas.

Description

technical field [0001] The invention relates to a flame-retardant and antibacterial hotel bed sheet and quilt cover fabric and a preparation method thereof. Background technique [0002] Polyvinyl alcohol (PVA) has a wide range of raw material resources and can be produced from natural gas, calcium carbide, petroleum and other resources. PVA fiber is produced by wet spinning method, the technical requirements for processing equipment are relatively low, and the processing cost is relatively low. In the conventional vinylon preparation method, the PVA fiber is acetalized through the reaction of formaldehyde and two adjacent hydroxyl groups, and the hydroxyl content in the fiber is reduced after a large number of hydroxyl groups are blocked, so that the vinylon (also known as vinylon) produced after acetalization Vinylon) fiber can withstand high temperature and wet conditions in dyeing and finishing processing, and its products have the advantages of high strength, good wear...
