Description
Technical field
The invention belongs to the non-woven industry of nonwoven, be specifically related to a kind of composite multi-functional needling material and manufacturing approach thereof.
Background technology
The development of environment-friendly materials now more and more receives the generally attention of countries in the world with application.After the seventies in 20th century, generally pay attention to the production and the application of environment-friendly materials both at home and abroad, make every effort to reduce significantly the consumption of the energy, thereby reduce environmental pollution and greenhouse effects.The Chinese environmental protection material industry is through nearly 20 years high speed development; Many products grow out of nothing; To variation, quality has formed ceramic fibre, glass wool, heat-insulating calcium silicate product etc. and is main kind from low to high from single; Improving constantly of Along with people's health environment-friendly theory, also increasingly high to the requirement of novel environment friendly material.But the most environment-friendly materials on the market are function singleness not only, but also may give people's the healthy hidden danger of bringing.For example be applied to the centrifugally glass-wool, asbestos friction material of household electrical appliance etc., inevitably can in heating process, produce carcinogen because of containing adhesive, the harm people's is healthy.
Summary of the invention
For solving the problems of the technologies described above, especially to being applied to the insulation material of household electrical appliance, the present invention provides the composite multi-functional novel environment friendly needling material and the manufacturing approach thereof of a kind of heat resistanceheat resistant radiation, nontoxic, high temperature resistant, damping, sound absorption, noise reduction.
Technical scheme of the present invention is: a kind of needling material, thickness is 3.0cm～3.5cm, is mainly processed through needling process by following raw materials by weight percent: the short yarn cutting 90%～95% of ultra-fine fibre glass, the short yarn cutting 5%～10% of high glass fiber.
Above-mentioned ultra-fine fibre glass and high glass fiber are alkali-free does not have the wax pattern glass fibre.
The short yarn cutting length of above-mentioned ultra-fine fibre glass is 51mm～81mm, and single fiber diameter is 3.5 μ m～5 μ m.
The short yarn cutting length of above-mentioned high glass fiber is 51mm～81mm, and single fiber diameter is 8 μ m～10 μ m.
A kind of manufacturing approach of needling material may further comprise the steps:
One, raw material is selected for use:
(1) the short yarn cutting of ultra-fine fibre glass;
(2) the short yarn cutting of high glass fiber;
Two, shredding: the raw material of step 1 being selected for use through opener carries out shredding, makes it reach fluffy state;
Three, mix: will pass through the raw material after the step 2 shredding, and press column weight amount percentage: the short yarn cutting 90%～95% of ultra-fine fibre glass, the short yarn cutting 5%～10% of high glass fiber fully mixes;
Four, combing: the blended fiber of step 3 gained is sent into carding machine be carded to fibre web, carding machine adopts single cylinder, two pass husband, two mixed and disorderly type;
Five, lapping: use the lapping machine that the fibre web of step 4 gained is carried out lapping, fibre web is overlapped to form fibrage repeatedly;
Six, clamping pressurization: use niproll that the fibrage of step 5 gained is pressurizeed; Reduce fibrolaminar thickness, add a niproll specially, do pressurization for the first time in lapping machine and feeding machine junction; Further, feed cotton uniformly for the feeding function and carry out assurance in advance the less thick of web;
Seven, feeding: use the feeding machine evenly to feed the fibrage of step 6 gained in the needing machine; The feeding machine is sent into web in the needing machine by two clamping skin curtains uniformly; The outlet of clamping skin curtain adjusts at any time spacing according to the thickness of web; Web is evenly got into reduce the broken needle rate, reduce the discounting of product on the other hand;
Eight, acupuncture: the fibrage of step 7 gained is processed needle fabric through needing machine.
The short yarn cutting length of ultra-fine fibre glass in the above-mentioned steps one is 51mm～81mm, and single fiber diameter is 3.5 μ m～5 μ m; The short yarn cutting length of high glass fiber is 51mm～81mm, and single fiber diameter is 8 μ m～10 μ m; Said ultra-fine fibre glass and high glass fiber are alkali-free does not have the wax pattern glass fibre.
The parameter of opener is in the above-mentioned steps two: the opening roller diameter is 450mm, and rotating speed is 600rpm; Main motor current is 7.5kw.
The parameter of carding machine is in the above-mentioned steps four: the cylinder rotating speed is 310rpm～350rpm.Two pass husband rotating speed is 19rpm～21rpm, and two mixed and disorderly rotating speeds are 19rpm～21rpm, and the card clothing model is cylinder 3510x2110.
The lapping machine that uses in the above-mentioned steps five is crossings on different level lapping machine, and the fibre web of step 4 gained is carried out the crossings on different level lapping, and lapping machine wallboard height is 1.86m～2.0m.The height of its wallboard of lapping machine that the present invention uses is than the high about 50cm of common lapping machine; The needling material more general because of needling material thickness of the present invention is thick, is 3cm～35cm, so the thickness of web will reach 30 multilayers; And being thickness by web, the height of lapping machine wallboard determines; So lapping machine wallboard must reach certain height, just can make web be unlikely to twine on the reciprocal dolly, could spread out qualified product.
The traverse of needing machine described in the above-mentioned steps eight is 70mm.The traverse of needing machine through improving the traverse of needing machine, guarantees that needling material reaches its thickness than the high about 20mm of general acupuncture machine.
Beneficial effect of the present invention: 1, function is complete: radioresistance, high temperature resistant, corrosion-resistant, electric insulation, damping, sound absorption, noise reduction etc.2, non-toxic and safe: needling material provided by the invention is not have the acupuncture of wax pattern glass fibre by alkali-free to form, and does not contain any binding agent, safety non-toxic.3, superior performance:, make the present invention have to be superior to the characteristic of other heat preserving and insulating materials because of excellent specific properties such as heat-resisting, anti-Zhang Du that ultra-fine fibre glass itself had, obdurability, fire-resistant, corrosion-resistant, electric insulation, flexibilities; Because of constituting countless thin holes in the fibrofelt, be omnidirectional three-dimensional micropore structure, fibrous inner structure is zigzag path, and pore diameter is little, and porosity is high, can reach 70～80%, makes its sound absorption qualities superior especially.4, of many uses: as, can be widely used in a plurality of fields because of it has the full advantage of function.As, its radioresistance, characteristic high temperature resistant, safety non-toxic can make it to be applied to household electrical appliance such as micro-wave oven, baking box; Its heat insulation sound absorbent performance can make it to be applied to building field; It is high temperature resistant, decay resistance can make it to be applied to heat supply pipeline, underground piping etc.; The protection that it is high temperature resistant, anti-Zhang Du, obdurability, characteristic such as fire-resistant, corrosion-resistant can make it to be applied to automobile ceiling, bonnet is heat insulation; Its superior sound absorption qualities can make it to be applied to muffler etc.; Its distinctive flexibility is convenient to cut out, cut, and can be widely used in human being's production, and each related application field of living reaches energy-saving and cost-reducing purpose.
