Description
Technical field
The present invention relates to a kind of retardant cotton, especially a kind of fire retardant cotton nonwoven fabrics.The present invention also provides the manufacture method of this fire retardant cotton nonwoven fabrics.
Background technology
The fire that the fibre burning causes has become one of great disaster of modern society, the result that the death by accident that is caused by fire is investigated shows, the fire that is caused by upholstery and textiles holds pride of place, discover that simultaneously the pernicious gas that discharges during flammable textile combustion substantially exceeds the anti-flammability textiles to the extent of injury of human body.Adopt fire resistance fibre and goods thereof with the substantive requirements of form of law and mandatory provisions in succession both at home and abroad at present, as explicitly calling in " fire service law " passed through recently at public places such as theater employing fire-retardant product, the mandatory employing fire-retardant product of decorative textile product that Ministry of Communications's requirement is used on railway and passenger vehicle, national security production general bureau and Safety of Coal Mine Production Surveillance Authority begin mandatory requirement downhole operations personnel and wear flame retardant textiles.Therefore, for preventing fire, produce fire resistance fibre and more and more be subject to people's attention.
Fire resistance fibre of the prior art generally has several classes, and wherein a class is a natural fabric, and natural fabric can only rely on post-processing approach to reach fire-retardant requirement, and also having a class is synthetic fiber, and it can make fire resistance fibre by add ways such as fire retardant in spinning solution.It is specialty fibers that one class is arranged again, for example carbon fiber etc.
The weak point of existing fire resistance fibre mainly is, flame retardant effect is bad, and the product fusing point is low, easily catches fire, and part is poisonous, and range of application is narrow, cost height, the very big cost expense of civilian military existence.Have, existing fire resistance fibre should not be made clothes because fusing point is not high again.In specialty fibers; Glass fibre can only be used as the flame retardant rubber coated base fabric, and carbon fiber and tower teflon price are too high.Therefore, the exploitation present situation of fire resistance fibre also is difficult to reach instructions for use.
Just realized at present the fire-retardant polyester fibre that industrialization is produced, its application is wider, though such flame-retardant textile can stop spreading of flame effectively, but, the phenomenon of fusion drippage at high temperature takes place in easily, and the fusion dropping makes the people scald easily, even the combustible material of the low ignition point that ignites, cause more conflagration, the user of service is caused potential injury.These defectives make its application be subjected to certain restriction, particularly use at aspects such as clothes to be not suitable for.Therefore development of new fire resistance fibre and textiles make it not only have the fire resistance while but also prevent that fusion from having become a urgent subject.
Summary of the invention
The objective of the invention is to improve the deficiencies in the prior art, a kind of nonwoven retardant cotton with flame-retardant and anti-dripping performance is provided.
Another object of the present invention is to provide the manufacture method of above-mentioned nonwoven retardant cotton.
The object of the present invention is achieved like this:
Fire retardant cotton nonwoven fabrics provided by the invention comprises that peace spins fire resistance fibre (Anti-fcell) and wash/polyester/polyester composite hot-melt short fiber, and wherein, pacifying the percentage by weight that spins fire resistance fibre is 70%～90%, and all the other are for washing/polyester/polyester composite hot-melt short fiber; Above-mentioned two kinds of fiber composite and/or IPN are combined into nonwoven fabric.
The preparation method of fire retardant cotton nonwoven fabrics provided by the invention is:
A. peace is spun fire resistance fibre (Anti-fcell) and washed/two kinds of raw materials of polyester/polyester composite hot-melt short fiber mixed according to the rules;
B. mixed raw material is carried out shredding by opener;
C. the mixture after the shredding is carried out the fiber combing;
D. carry out lapping with the fiber after the combing;
E. the lapping fiber is carried out processing and forming, make nonwoven fabric with a thickness;
F. the nonwoven fabric of making is cut edge, be rolled into and be finished product.
In the E step, the method for described processing and forming can be:
A. needle point method:
By end curtain is that convoying curtain is sent constantly into the fibre web of lapping in the needing machine, carries out acupuncture for the fiber of lapping, fiber is intertwined under the effect of pricker and form the nonwoven fabric of a thickness, then, again by scalding the moulding of roller hot pressure.
In acupuncture course, when fibre web feeding acupuncture, when many pieces of thorns are needled into fibre web, thorn hook on the pricker will drive the fiber of fibre web surface and subsurface, by the in-plane of fibre web movement in vertical direction to fibre web, make fiber produce displacement up and down, and the fiber that produces displacement up and down just produces certain extruding to fibre web, make in the fibre web fiber draw close and be compressed.After pricker reaches certain degree of depth, the pricker bottom out, because thorn hook cause forward, the fiber that produces displacement breaks away from the thorn hook and stays in the fibre web with plumbness almost, hammered into fibre web just as many fibre bundles " pin ", thereby the compression that fibre web is produced can not recover, if on every square centimeter fibre web through tens of or up to a hundred time repeated localised puncture, just a considerable amount of fibre bundles have been thrust fibre web, frictional force in the fibre web between fiber and the fiber strengthens, fibre web intensity raises, increase in density, and fibre web has formed has certain brute force, density, the needle punched non-woven fabrics of performances such as elasticity.
Acupuncture is divided into facing down into the following acupuncture of pin and go into two kinds of the last acupunctures of pin from bottom to top from fibre web.Needle point method provided by the invention successively descends acupuncture and two acupuncture courses of last acupuncture for fibre web, like this, and can be so that the nonwoven fabric intensity of making, density and flexible combination property be superior.
In order to make acupuncture course carry out smoothly, before normal acupuncture, carry out a pre-needling process earlier, promptly the bestock of pre-pricking machine is less, and pin is bigger deeply, and its main purpose is that the fibre web that cohesive force is little between high loft and fibre web is carried out acupuncture.
The acupuncture of using this form is to have higher and bulking intensity because of the fibre web of sending into needing machine through the lapping machine, just produces certain brute force by the cohesive force between fiber and the fiber, but powerful very poor, needs sting in advance through pre-pricking machine earlier.
After the pre-needling, carry out main acupuncture, main acupuncture can be: by following needing machine fibre web is descended acupuncture earlier, then, acupuncture on fibre web being carried out by main needing machine.
Adopt this elder generation pre-, the needle-punching method of the main thorn in back can make the nonwoven fabric cloth cover more even, smooth, and is powerful, density is bigger, thereby makes fire retardant nonwoven fabric obtain better flame retardant effect.
The degree of depth of acupuncture can not surpass the fibre web thickness of lapping, otherwise fibre fluff can appear in two surfaces of nonwoven fabric, makes the cloth cover out-of-flatness, even the phenomenon of broken needle can occur.The degree of depth of acupuncture can not be too shallow, otherwise pricker can not penetrate web layer, thereby cause the brute force of nonwoven fabric to descend, even the phenomenon of nonwoven fabric layering occurs; Needle-punching method provided by the invention, the degree of depth of its pre-needling is suitable with regard to thickness with the shop of fibre web, dark (depth of needling) 7～10mm of pre-needling eedle, dark (depth of needling) 5～7mm of following acupuncture eedle, dark (depth of needling) 3～4mm of main acupuncture eedle.But the degree of depth sum of the degree of depth of following acupuncture and last acupuncture greater than the shop of fibre web with regard to thickness.Like this, the degree of depth of acupuncture all less than the thickness of fibre web, the problem that fibre fluff appears in nonwoven surface can not occur up and down, but makes fibre web the problem of layering, superior performances such as brute force not occur.
