The method of the invention has the advantages of simple process, less equipment investment, low production cost and easily realized industrialization.
Description
Technical field
The present invention relates to a kind of method for modifying flame of acrylic fibers yarn, belong to chemical fibre manufacturing technology field.
Background technology
The acrylic fibers yarn is that the yarn raw material is used in weaving, and it has characteristics such as good warmth retention property, dyeability and simulate wool property.But the acrylic fibers yarn also has a lot of shortcomings, and is poor like hygroscopicity, be prone to produce static, very easily burning etc., and is prone to emit toxic gas in the burning and is detrimental to health and causes secondary environmental pollution.For improving the fire resistance of acrylic fibers yarn, various countries have created many flame resistant methods, as processing Vinyon N with using with the dichloroethylene copolymerization, with fire retardant and the polyacrylonitrile blended flame-retardant acrylic fibres of processing such as phosphorus system, chlorine system, nitrogen systems, with thermal oxide system fire resistance fibre etc.
Summary of the invention
The purpose of this invention is to provide that a kind of technology is simple, cost of investment is low, have the method for modifying flame of the acrylic fibers yarn of anti-flaming function.Its technology contents is:
A kind of method for modifying flame of acrylic fibers yarn; It is characterized in that: at first the acrylic fibers yarn is joined and react the acrylic fibers yarn of processing copper ions in the copper ions aqueous solution; Copper ions acrylic fibers yarn joined in the mixed solution that hydrazine hydrate and reaction promoter form soaked 3～30 minutes; Perhaps moisture content is extracted or dried into to the acrylic fibers yarn is not less than 50% together with mixed solution with the acrylic fibers yarn then; Put in the HTHP decatize typing pot under 100～200 ℃ of temperature conditions dry blowing or decatize 30～300 minutes, and processed fire-retardant acrylic fibers yarn.
The method for modifying flame of described acrylic fibers yarn, the copper ions aqueous solution is formulated by copper sulphate or stannous chloride and water, and copper sulphate or stannous chloride mass percent concentration are less than 3%.
The method for modifying flame of described acrylic fibers yarn; The reaction condition of the acrylic fibers yarn and the copper ions aqueous solution is: the bath raio 1: 10～15 of the acrylic fibers yarn and the copper ions aqueous solution; 10～100 ℃ of temperature; Reacted 1～30 minute, and took out then and clean, promptly obtain copper ions acrylic fibers yarn through extracting or dry or drying.
The method for modifying flame of described acrylic fibers yarn, reaction promoter are meant one or more the combination in any in NaOH or potassium hydroxide and surfactant, scouring agent, levelling agent, bleeding agent, retarding agents, the emulsifying agent.
The method for modifying flame of described acrylic fibers yarn, the atmosphere in the HTHP decatize typing pot can be an air, also can be nitrogen, also can the air emptying in the pot be become the steam atmosphere with overheated or saturated vapor.
The method for modifying flame of described acrylic fibers yarn; The mass percent concentration of hydrazine hydrate is 3%～30% in the mixed solution; The mass percent concentration of NaOH or potassium hydroxide and other reaction promoter is all less than 3%, the bath raio of copper ions acrylic fibers yarn and mixed solution 1: 6～15.
The present invention compared with prior art has following advantage:
1, the reaction in the mixed solution of hydrazine hydrate and reaction promoter composition of acrylic fibers yarn just can obtain flame retardant effect.
2, production technology is simple, and equipment investment is few, and production cost is low, easy realization of industrialization.Only need a HTHP decatize typing pot and seldom process matched therewith and equipment, just can be processed into the acrylic fibers yarn flame-retardant acrylic fibre yarn of anti-flaming function.
