Abstract
The invention provides a wool fabric flame retardation finishing method, which comprises the following steps: A)pre-treating fabric, performing ultrasonic treatment for 30-60 minutes with frequency of 30-40 KHz; B)pre-emulsifying on a monomer: emulsifying a vinylphosphonic acid monomer by an emulsifier to form an emulsion, adjusting pH value of 3-4; C)performing a grafting reaction: heating a rolling groove filled with the monomer emulsion to the temperature of 80-90 DEG C, continuously heating to the temperature of 90-100 DEG C and reacting for 1-2 hours; D)washing; and E)drying. According to the wool fabric through the flame retardation finishing, the limited oxygen index after washing for 30 times is still at more than 27%, the wool fabric enables self-extinguishing while meeting fire, and has good perdurable flame resistance performance; the ultrasonic treatment is used for pretreatment, and is in favor of subsequent chemical grafting; simultaneously, the wool fabric through ultrasonic treatment has good shrinkproof performance and fluffy degree.
Description
Technical field
The present invention relates to a kind of method for sorting of fabric, especially relate to a kind of flame-retardant finishing method of wool fabric.
Background technology
Wool is one of most important raw material in textile industry, because it is soft, quality is strong, good elasticity and warmth retention property, gloss are naturally soft, building, take, family is spun etc., and aspect application is very extensive.Wool fibre mainly consists of keratin, and carbon containing 48～50%, nitrogen 15%～16%, sulphur 3%～4%, hydrogen 6%～7%, when regain is 15%(relative humidity 60%).Because have high nitrogen content, the flame resistant performance of wool fibre own is better, and its ignition temperature is about 570～600 ℃, and limited oxygen index (LOI) is about 25%, if but in reality, have higher fire-retardant requirement, also need it further to carry out flame treatment.
The flame-proof treatment of early stage wool is to adopt borax. BAS infusion process, and product is mainly used in aircraft decorating cloth, and this method flame retardant effect is good, but washability is poor.After the sixties, adopt Tetrakis hydroxymethyl phosphonium chloride (THPC) and derivative thereof, sulfamate to process wool, can obtain good anti-flammability and washability.After this develop into again and utilize the fluoro complex of titanium, zirconium, carboxylic acid complex compound to process wool, this method can obtain permanent fire retardant level, so application is more extensive.In order to meet requirements at the higher level, develop again the high temperature resistant fabric of wool and other fiber blend of resistance to combustion.Adopt blending technology can effectively improve the fire resistance of wool, but because its complex process, equipment requirement are high, and blend fibre is expensive, and this technology is restricted to a certain extent.
Summary of the invention
The flame-retardant finishing method that the object of this invention is to provide a kind of wool fabric.
The present invention will solve is that the finishing effect that exists in existing flame-retardant finishing method is not ideal enough, operation is numerous and diverse and the defect such as finishing agent is big for environment pollution.
Technical scheme of the present invention is: a kind of flame-retardant finishing method of wool fabric, and described method at least comprises the steps: the preliminary treatment of a. fabric: wool fabric is cleaned and is placed in warm water, and the ultrasonic wave that is 30～40KHz by frequency is processed 30～60 minutes; B. monomer pre-emulsification: vinyl phosphate monomer is placed in to groove, adds the emulsifying agent that accounts for monomer mass 6～8%, form emulsion after high-speed stirred, regulating PH is 3～4; C. graft reaction: the groove that monomer emulsions is housed is warming up to 80～90 ℃, adds initator and after pretreated wool fabric, continue to be warming up to 90～100 ℃ of reactions 1～2 hour; The consumption of described initator is 0.5～2.0% owf, and bath raio is 1:10～30; D. washing: alternately wash three times with hot water and cold water; E. dry: the wool fabric after washing is dried 3～5 minutes at 70～80 ℃; Wool fabric after drying is baked to 1～3 minute at 120～140 ℃.
Described vinyl phosphate monomer is wherein a kind of in methylacryoyloxyethyl diethyl phosphate DEMEP, acrylyl oxy-ethyl diethyl phosphate DEAEP, acryloyl-oxy methyl diethyl phosphate DEAMP or acryloyl-oxy methyl dimethoxy base phosphate DMAMP.
The Compositional type emulsifying agent that described emulsifying agent adopts nonionic emulsifier polyoxyethylene ether sorbitan monooleate Tween 80 and sorbitan monooleate Span 80 to form, described Tween 80 is 1:1 with the mass ratio of Span 80.
Described initator is wherein a kind of in potassium peroxydisulfate, potassium permanganate or dibenzoyl peroxide BPO.
The beneficial effect that the present invention produces is: compared with prior art, flame-retardant finishing method provided by the invention, by chemical graft process, vinyl phosphate is monomer-grafted to wool fibre, make wool fabric there is good flame retardant effect; Wash after 30 times, its limited oxygen index of the wool fabric after flame-proof treatment, still more than 27%, is met fire and still can certainly be put out, and has good durable flame-proof performance; Wool fabric to be arranged is processed with ultrasonic wave in advance, can make wool fibre expanded, the scale layer of wool surface is opened, thereby be more conducive to the carrying out of subsequent chemistry grafting; Meanwhile, the wool fabric after ultrasonic wave is processed also can have good shrinkproof performance and bulking intensity.
The specific embodiment
Below in conjunction with embodiment, the invention will be further described.
A flame-retardant finishing method for wool fabric, described method at least comprises the steps: the preliminary treatment of a. fabric: wool fabric is cleaned and is placed in warm water, and the ultrasonic wave that is 30～40KHz by frequency is processed 30 minutes; B. monomer pre-emulsification: monomer methylacryoyloxyethyl diethyl phosphate DEMEP is placed in to groove, add the emulsifying agent that accounts for monomer mass 6%, described emulsifying agent adopts the compound nonionic emulsifier that the mass ratio of Tween 80 and Span 80 is 1:1, after high-speed stirred, form emulsion, regulating PH is 3.5; C. graft reaction: the groove that monomer emulsions is housed is warming up to 85 ℃, adds the initator dibenzoyl peroxide BPO of 0.5～2.0% owf and after pretreated wool fabric, continue to be warming up to 95 ℃ of reactions 2 hours, bath raio is 1:30; D. washing: alternately wash three times with hot water and cold water; E. dry: the wool fabric after washing is dried 3 minutes at 80 ℃; Wool fabric after drying is baked to 2 minutes at 130 ℃.
Wool fabric to be arranged is processed with ultrasonic wave in advance, can make wool fibre expanded, the scale layer of wool surface is opened, thereby be more conducive to the carrying out of subsequent chemistry grafting.Meanwhile, the wool fabric after ultrasonic wave is processed also can have good shrinkproof performance and bulking intensity.By chemical graft process, vinyl phosphate monomer is connected on wool fibre, makes wool fabric there is good flame retardant effect; Wash after 30 times, its limited oxygen index of the wool fabric after flame-proof treatment, still more than 27%, is met fire and still can certainly be put out, and fire resistance is good, and has durable flame-proof performance.
