Embodiment 1

[0017] The graft flame-retardant modification method of embodiment 1 woolen fabric comprises the following steps:

[0018] S1: Preparation of emulsified flame retardant finishing liquid. Add allyl phosphate and emulsifier to deionized water, stir on high-speed emulsifier at a speed of 10000r / min for 5 minutes, add initiator and stir evenly to prepare emulsified flame retardant finishing liquid ;

[0019] S2: Immerse the woolen fabric in the emulsified finishing solution at a bath ratio of 1:40, adjust the pH value of the reaction system to 2.5 with an acidic component, close the reaction system, heat to 100°C, keep it warm for 60 minutes, and then take out the woolen fabric. Washing in warm water at least twice, then washing in cold water, and finally drying to obtain the grafted flame-retardant modified wool fabric.

[0020] The initiator is potassium persulfate. The addition amount of the initiator in the finishing solution is 1% owf, and the addition amount of allyl phosp...

Embodiment 2

[0024] The difference between embodiment 2 and embodiment 1 is:

[0025] S1: Stir on the high-speed emulsifier at a speed of 15000r / min for 5min;

[0026] S2: Immerse the wool fabric in the emulsified finishing solution at a bath ratio of 1:30, adjust the pH value of the reaction system to 4 with an acidic component, close the reaction system, heat it to 85°C, and keep it warm for 120 minutes.

[0027] The initiator is dibenzoyl peroxide. The addition amount of the initiator in the finishing solution is 1.8% owf, and the addition amount of allyl phosphate is 50% owf.

[0028] The emulsifier is selected from fatty alcohol polyoxyethylene ethers whose number of added ethylene oxide is 7. Allyl phosphate is diethyl allyl phosphate.

[0029] The acidic component is citric acid.

Embodiment 3

[0031] The difference between embodiment 3 and embodiment 2 is that

[0032] S1: Stir on the high-speed emulsifier at a speed of 13000r / min for 5min;

[0033] S2: Immerse the wool fabric in the emulsified finishing solution at a bath ratio of 1:35, adjust the pH value of the reaction system to 3.4 with an acidic component, close the reaction system, heat to 93°C, and keep warm for 90 minutes.

[0034] The initiator is potassium permanganate. The addition amount of initiator in the finishing solution is 1.4% owf, and the addition amount of allyl phosphate is 65% owf.

[0035] The emulsifier is fatty alcohol polyoxyethylene ether phosphate. Allyl phosphate is diethyl allyl phosphate.

[0036] The acidic component is 2,3-dihydroxysuccinic acid.

Abstract

The invention discloses a wool fabric grafting fire-retardant modification method. The wool fabric grafting fire-retardant modification method comprises the three steps of sodium alginate oxidation, fabric finishing with oxidized sodium alginate, and ion exchange treatment. The wool fabric grafting fire-retardant modification method takes polyaldehyde sodium alginate as a finishing agent for forming films on the surface of fiber, the sodium alginate covering the surface of the fiber can isolate air and heat to promote char-forming and heat-absorbed water vaporization and further reduce thermaldecomposition temperature; the oxidized sodium alginate can be decomposed prior to alpaca wool when heated so as to absorb heat and meanwhile reduce the surface temperature of the fabric to further achieving fire-retardant effects.

Description

technical field [0001] The invention relates to the technical field of wool reinforcement, in particular to a method for grafting and flame-retardant modification of wool fabrics. Background technique [0002] The flame retardant finishing of wool in the prior art is divided into three types: non-permanent, semi-permanent and permanent according to the duration of the flame retardant effect. Non-permanent flame-retardant finishing is not resistant to water washing. For example, wool can be temporarily flame-retardant after being impregnated and dried in solutions such as orthophosphoric acid, metaphosphoric acid, sulfuric acid, sulfamic acid, and boric acid. It will fail after washing; semi-permanent flame-retardant finishing can withstand five times Left and right washing, or resistant to multiple washings under certain conditions, permanent flame-retardant finishing can withstand more washing times, semi-permanent and permanent flame-retardant finishing in the prior art su...
