Abstract
The invention discloses a manufacturing method of a non-woven needle-punched jacquard pad. The manufacturing method comprises following steps of opening a net, mixing, laying the net, needling, secondary needling, rolling, raising and needling the texture. The manufacturing method of the non-woven needle-punched jacquard pad has following beneficial effects: forming processes such as two-sided needling and secondary needling are utilized so that a fiber net is wound densely more; the needle-punched jacquard pad is not easily deformed and has high strength; the roller forming step is taken on a roller press and a water-spraying humidifying process goes on prior to rolling depression so that the fiber net is more easily deformed; a Jacquard technique is controlled at the same time; and the manufactured non-woven needle-punched jacquard pad is high in deformation resistance and better in flatness.
Description
Technical field
The invention belongs to field of fabric producing technology, particularly relate to a kind of preparation method of nonwoven needled jacquard pad.
Background technology
Non-woven material is made up of orientation or random fiber, is environment-friendly materials of new generation, has protection against the tide, ventilative, pliable and tough, light weight, not combustion-supporting, easy decomposition, nontoxic nonirritant, rich color, the feature such as to use again cheap, capable of circulation.As adopted polypropylene granules to be raw material more, batch continuous one-step produce through high-temperature fusion, spray silk, lapping, hot pressing.Non-woven material has ventilative, air-breathing, non-directional, light weight and the easy advantage such as decomposition, is thus all widely used in health care, clothes, industry and the field such as agriculture.
The kind of non-woven material is more, and performance differs, the difference of its raw material and preparation method, determines performance and the purposes of non-woven material.CN101324012A discloses a kind of manufacture method of bast fiber nonwoven fabric, shredding that it comprises the steps: (1) mixes: by flax fibre shredding once, viscose fibre and other fiber openings twice or repeatedly, by above-mentioned flax fibre, viscose fibre and other fibers mixture after shredding; (2) above-mentioned blended fiber is processed into net; (3) acupuncture is shaping: the fiber web obtained in step (2) is carried out acupuncture by needing machine; (4) hot-roll forming: the above-mentioned fiber web obtained after acupuncture is delivered to roll extrusion on roll squeezer, carries out hot-roll forming.This manufacture method is simple, and this manufacture method limits its shredding number of times for the shredding of flax fibre in addition, thus avoids because shredding causes flax fibre to rupture often, and then ensure that the length of fiber, is convenient to the manufacture of nonwoven fabric; Carry out twice or repeatedly shredding other fibers except flax fibre, ensure that the abundant shredding of these fibers, be convenient to the manufacture of nonwoven fabric equally, the cost of prepared nonwoven fabric is higher simultaneously, and prepared nonwoven fabric intensity is difficult to ensure, quality is unstable.CN102691172A discloses a kind of Chinese fiber crops needle fabric and preparation method thereof.The method comprises the steps: china-hemp fibers to mix with at least one in long-staple cotton fiber and viscose, then feeds cotton, combing, lapping, drawing-off and acupuncture namely obtain described Chinese fiber crops needle fabric through thick shredding, smart shredding, air pressure successively.The Chinese provided by the invention fiber crops needle fabric be quantitatively 150 ~ 300g/m
2; Can be used as the aspects such as heat-insulation warm keeping material, air filtration, needle punched carpet, automotive trim, Application Areas is comparatively wide, but due to raw material employing china-hemp fibers and long-staple cotton fiber, cost is higher.CN103614861A discloses a kind of polyester filament needle-punched geotextiles production method, the technological process of the method be polyester slice enter after drum dried efficient from vented screw extruder through metre filter, enter spinning machine again and spray melt filament by measuring pump from spinnerets, again by lateral blowing cooling forming, tubular type air drawing, the lapping of oscillating-chip yarn swaying machine, fibre web is layered in woven cloth, woven cloth is synchronously unreeled by the unreeling machine before lapper, woven cloth and net enter pre-needling machine acupuncture pre-setting again, the sizing of reinforcing again of main needing machine 1, the reparation sizing of main needing machine 2, cloth is held again through holding cloth tensioner, finally by trimming rolling.The method makes high strength polyester filament yarn geotextiles, and the high and low elongation of intensity of product, is applied in engineering, longer service life, but preparation method's more complicated.
Summary of the invention
The object of the invention is the shortcoming for existing in prior art, providing that a kind of intensity is high, not yielding, flatness good and the preparation method of the nonwoven fabric of environmental protection.The solution of the present invention, a kind of preparation method of nonwoven needled jacquard pad, comprises the following steps:
(1) carry out shredding by polyester fiber and polypropylene fibre input opener, the fibrous raw material of shredding is sent in mixed cotton and mixes;
(2) mixed fibrous raw material is sent into carding machine to carry out being carded to fiber web, the net spee that goes out of carding machine is 2.5-3.0m/min;
(3) fiber web is flowed to lapping machine, laying becomes the multi-layered web of 16-24 layer;
(4) multi-layered web is delivered to needing machine, carry out acupuncture, comprise front acupuncture and reverse side acupuncture;
(5) the above-mentioned fiber web obtained after acupuncture is delivered to roll forming on roll squeezer;
(6) fiber web napping step (5) obtained, needled jacquard, namely obtain nonwoven needled jacquard pad.
Preferably, in described nonwoven needled jacquard pad, the weight ratio of polyester fiber and polypropylene fibre is 2-5:1; And the color of polyester fiber and polypropylene fibre at least comprises two kinds.
Preferably, the fusing point of described polyester fiber is 250-255 DEG C, and the fusing point of polypropylene fibre is 165-170 DEG C.
Preferably, in described step (4), the degree of depth of needing machine is 11-15mm, and speed is 3.5-4.0m/min, and needling density is 400-450 thorn/cm
2.
Preferably, in described step (4), fiber web is after front acupuncture and reverse side acupuncture, then carries out secondary acupuncture, and secondary acupuncture comprises front acupuncture and reaction acupuncture, and depth of needling is 9-10mm, and speed is 3.0-3.5m/min, and needling density is 180-220 thorn/cm
2.
Preferably, before fiber web delivers to roll squeezer in described step (5), first carry out water spray and add wet process, play the effect of cooling on the one hand, on the other hand, due to soaking of water, fiber web is more easily shaped, not yielding.
Preferably, the jacquard weave degree of depth of the needled jacquard in described step (6) is 3-6mm, and needling density is 260-340 thorn/cm
2, speed is 1.2-1.7m/min.Speed in jacquard weave process is extremely important, and jacquard weave process medium velocity is too fast, easily causes the fracture of fiber, affects intensity and the elongation at break of needled jacquard pad, and jacquard speed is too slow, and elaborate pattern is neat not, affects attractive in appearance.
Preferably, the roller temperature of described roller machine is for being 160-200 DEG C.
Preferably, the surface density of described nonwoven needled jacquard pad is 200-350g/m
2.
The invention has the beneficial effects as follows: nonwoven needled jacquard pad of the present invention adopts the fiber of polyester fiber and polypropylene fibre two kinds of different melting points; Become net process to mixed fiber, and use positive and negative acupuncture and secondary acupuncture forming processes, the winding of fiber web more crypto set, needled jacquard pad is not yielding, improves the intensity of needled jacquard pad; Take roll forming step on roll squeezer, before roll extrusion, carry out water spray adds wet process simultaneously, and fiber web is more easily shaped, and also controls jacquard process, and prepared nonwoven needled jacquard pad resistance to deformation is strong, and intensity is high, and flatness is good.
