Description
[technical field]
The present invention relates to a kind of preparation method of flame-retardant and anti-dripping functional fibre, belong to textile yarn technical field.
[background technology]
Flourish along with the polymeric materials such as plastics, rubber, synthetic fiber and goods thereof, instead of rapidly the materials such as traditional steel, metal, cement, timber and linen-cotton, be widely used in each department of the national economy such as industrial or agricultural and military affairs, closely bound up with people's daily life.But these polymer great majority are inflammable, combustible materials, when burning, HRR is large, and calorific value is high, flame propagation speed, not easily extinguishes, and sometimes also produces dense and toxic gas, works the mischief to environment, jeopardizes the life security of people.Therefore the anti-flammability how improving polymer has become a urgent problem, and to carry out flame treatment to polymer be reduce one of important measures of fire.More external developed countries have just worked out the laws and rules about use flame retardant products one after another in the eighties of last century sixties, and various countries formulate strict implementation criteria in succession to fire-retardant product.Along with the continuous improvement of people's lives and environmental condition, people are more and more higher to flame retardant textiles performance requirement, should drop into the exploitation that strength and fund strengthen fire resistance fibre.A few days ago, Chinese University of Science and Technology SKLFS scientific research personnel, studies successful Novel clean, high efficiency flame retardant material with molecular design method, and this technological achievement has been put into national development for hi-tech industry plan.Flame-retardant polymer modified clay nano composite material " leafing nano composite material " and " embedding nano composite material " method, reasonably polymer and inorganic matter are combined, utilize new flame-retarded technology to be prepared, effectively can overcome the deficiency of existing fire proofing.
The blended union of flame-retardant textile and function and serviceization are becoming a kind of new development trend, and present countries in the world have difunctional and multi-functional flame-retardant textile by the blended union exploitation of fire resistance fibre.Current most fire resistance fibre or fabric only have anti-flaming function, can not meet the particular/special requirement of some department, as flame-retardant water-repellent, fire-retardantly refuse oil, flame-retardant and anti-static, and development flame-retardant multifunctional product is imperative.As adopted various ways to combine in production method, waterproof, oil-repellent finiss are carried out to flame-retardant fibre fabric; Fire resistance fibre yarn and conductive fiber is adopted to interweave to produce anlistatig fire resistance fibre; Fire resistance fibre and high-performance fiber is utilized to carry out blended union production high-temperature resistant fabric; Adopt the fiber blend such as fire resistance fibre and cotton viscose glue to improve final products comfortableness and to reduce costs.
Existing tens kinds of fire resistance fibre on present domestic and international market, the fire resistance fibre mainly flame-resistant terylene of tradition processing, flame-retardant acrylic fibre, Flame Vinylon.Along with the progress of science and technology, various countries are the multiple fire resistance fibre of Development and Production recently, as Fanglun 1313, polyamide one imide fiber, polyimides 2080 fiber, heterocycle polymer polybenzimidazole fiber (PIM2080), phenolic fibre.The flame retardant effect of these special type flame retardant fibers is all relatively good, has very large purposes in industry and special dimension.Preparation technology's complex procedures on the one hand of existing fire resistance fibre, requires harsher, higher to the requirement of technical staff in preparation process on the other hand, is difficult to universal.
[summary of the invention]
The object of the invention is to: for defect and the deficiency of prior art, provide a kind of preparation method of flame-retardant and anti-dripping functional fibre, this kind of preparation method is simple to operation, through fire resistance fibre prepared by this kind of method, regain is less than 2%, has intensity high, good springiness, the plurality of advantages such as dimensionally stable, its pole oxygen index (OI) can reach 28%-34.6% simultaneously, and fabric is passing through washing, flatiron, after wearing and tearing, fire resistance can not change, and has permanent fire retardant.
For achieving the above object, the technical solution used in the present invention is:
The preparation method of a kind of flame-retardant and anti-dripping functional fibre of the present invention, comprises the following steps:
Step one, prepare flame-retardant acrylic fibre fiber, select collection phosphorus and nitrogen, the BACN that phosphorus sulphur nitrogen is integrated, is applied in polyacrylonitrile by copolymerization or blended mode, thus spinning flame-retardant acrylic fibre;
Step 2, enter griping cotton machine, from the bale of cotton, capture raw cotton feed to front machinery;
Step 3, enter cotton blender machine, the raw cotton of various heterogeneity is mixed evenly, simultaneously can tentatively shredding removal of impurities;
Step 4, enter opener, the raw cotton pressed is loosened into less cotton block or flock, in order to mixing, the carrying out smoothly of removal of impurities effect;
Step 5, enter hopper, according to the weight of regulation, sheet cotton evenly, is stably fed carding machine by lapper;
Step 6, enter carding machine, the chemical fibre sent here is rolled up the chemical fiber layer supplied by automatic flower feeding machine and carry out shredding and divide comb removal of impurities;
Step 7, by pre-drawing machine, make fiber pre-drawing, by drawing-off and and the synergy of closing, fortifying fibre mixed effect;
Step 8, enter Speed frames, twist slivering by the product after drawing-off by Speed frames, coarse sand adopts and spaces greatly, and the technological principle of heavily pressurizeing, can effectively reduce resultant yarn details like this, Spinning Evenness is necessarily improved;
Step 9, enter fine spining machine, become yarn by the drawing-off of fine spining machine product, adopt larger back zone roller gauge, less nip gauge and less back zone drafting multiple, choose twist factor on the low side;
Step 10, by after drawing-off yarn import automatic winder, on bobbin winder check filter yarn, suitable Yarn tension to be selected during this operation, improve yarn quality;
Step 11, enter two-for-one twister, evenly twisted by two-for-one twister.
In the present invention: described step one flame-retardant acrylic fibre fiber substitutes short route blowing room machinery group by using opener and automatic feeding machine in shredding operation, suitably reduce cylinder speed simultaneously, and strengthen spacing between cotton roller, what wherein the rotating speed of carding step cylinder licker-in speed and licker-in will be suitable is low, mixing in doubling step reasonable disposition draft process.
