Abstract
The invention relates to a method and equipment for manufacturing one-step pore-formed hot air nonwoven cloth. The method comprises the following steps: opening, carding, bonding carded fibers together through thermal forming to form nonwoven cloth with a fiber web structure, at the same time, punching the hot air nonwoven cloth, and finally slitting. The equipment for realizing the method comprises an opener, a carding machine, an oven and a slitting machine, wherein a conveyor belt in the oven is a card clothing conveyor belt. The nonwoven cloth, manufactured by the method, has the advantages of softness, comfort, uniform hole size, and stable hole shape, the hole keeps the original shape after the one-step pore-formed hot air nonwoven cloth is torn, and meanwhile, the technological process is simplified and the production efficiency is improved.
Description
Technical field
The present invention relates to the manufacture method of perforated non-woven fabric and perforated non-woven fabric, be specifically related to manufacture method and the equipment thereof of disposal pore-forming hot-wind nonwoven cloth.
Background technology
At present, the surface material of using for the disposable absorbent article such as sanitary napkin, paper diaper, for improving the performances such as its liquid permeability, water conservancy diversion, makes liquid can import rapidly the inside of amenities, conventionally can on surface layer, punch.
A kind of method of making perforated non-woven fabric is: allow adhesion-molded fibre web by one group of intermeshing porcupine roller, by pin, fiber is squeezed out, thereby on fibre web, form the shape hole consistent with the root of pin, and by heating, fibre web has been carried out to regelate moulding.The defect of this method is that, after regelate finishes, the hole meeting dilatation having squeezed, causes hole shape size inhomogeneous.
In addition, the method of the making perforated non-woven fabric also having is: after making nonwoven fabric, punch again, when punching, be generally to carry out with hot acupuncture at normal temperatures, non-woven fabrics fiber will hot melt at acupuncture position like this, cooled pore area has hard melting-clinkering edge, this hole, owing to having formed many hard and sharp keen edges, makes jagged sense in nonwoven fabric sense of touch, has reduced the comfort level of dress.If punched under uniform temperature control in order to reduce burr sense, so just need to increase a set of baking oven equipment, cause production cost to increase.
Or, after making nonwoven fabric, punch with normal temperature acupuncture at normal temperatures, squeeze and portal by acting in nonwoven fabric space of mechanical force, similar with the first method of introducing, the pore volume of extruding so easily recovers, and causes hole size inequality.
Squeeze the manufacture method of fiber pore-forming by porcupine roller, all have following shortcoming: after the product of formation tears, the hole of being beaten is yielding, fall into oblivion even gradually hole, revert to plane, and pore size is inhomogeneous, production efficiency is low.
Summary of the invention
The defect existing for overcoming said method and equipment, technical problem to be solved by this invention is, a kind of manufacture method of disposal pore-forming hot-wind nonwoven cloth is provided, make the hole size that distributes on nonwoven fabric evenly, not yielding, punching place is without harsh feeling, and production efficiency improved.
Corresponding therewith, another technical problem that will solve of the present invention is, provide can make the hole size that distributes on nonwoven fabric evenly, not yielding, without harsh feeling, and the high process equipment of production efficiency.
With regard to the manufacture method of disposal pore-forming hot-wind nonwoven cloth, the technical scheme that the present invention deals with problems comprises the steps:
(a) fiber is carried out to shredding;
(b) fiber after shredding is carried out to combing;
(c) nonwoven fabric of making is cut into required size;
Described step (b) afterwards, step (c) also comprises before fiber good combing is bonded together and is formed the nonwoven fabric of fibre net structure by thermoforming, and on hot-wind nonwoven cloth, punch simultaneously, when making nonwoven fabric, make hole, whole punching hot-wind nonwoven cloth is that one-shot forming generates.
Technique scheme, in punching process, makes fiber fit in punch device by hot-blast pressure.
In technique scheme, described in be thermoformed into hot rolling or heat bonding.
With regard to the manufacturing equipment of disposal pore-forming hot-wind nonwoven cloth, the manufacturing equipment of technical solution problem of the present invention comprises opener, carding machine, baking oven, cutting machine, wherein, the conveyer belt in described baking oven is card clothing formula conveyer belt, has perforating needle in the outer surface stationary distribution of conveyer belt.
In technique scheme, described perforating needle can be designed to different shapes as required, is preferably cone; The gap of arranging of perforating needle can be designed according to pitch of holes, and the diameter of perforating needle is according to required aperture design.
While manufacture on production line, first fiber is carried out on opener to shredding, then on carding machine, carry out combing, after combing is complete, material is sent into the card clothing formula conveyer belt in baking oven, in baking oven, carry out thermoforming, in thermoforming process, by hot-blast pressure, fiber is fitted on card clothing formula conveyer belt, perforating needle sees through fibroreticulate gap and passes, and then makes fiber disc around the root of pin, along with hot-air penetrates fibre web, transfer heat to fiber, make its melting and produce bonding.And be coiled in fiber around perforating needle root in bonding, form the identical hole of root external diameter of aperture and perforating needle.Finally, fiber is cut after fixed network sizing.
Remarkable result of the present invention is:
1. the hole forming by above-mentioned processing method, pore size is even, and pass is stable, tear rear pass and maintain the original state, and the nonwoven fabric of making (comprising peripheral region, hole) is soft comfortable, without harsh feeling.
2. the process of said method production punching hot-wind nonwoven cloth is one-shot forming, makes hole when making nonwoven fabric, need not, using punching as an independent processing step, simplify technological process, has improved production efficiency.
Accompanying drawing explanation
Be described further below in conjunction with drawings and Examples.
Fig. 1 is process chart of the present invention.
Fig. 2 is the card clothing formula conveyer belt structure schematic diagram in baking oven of the present invention.
Wherein, 1-baking oven, 2-card clothing formula conveyer belt, 3-perforating needle, 4-fiber, the 5-hot-wind nonwoven cloth that punches.
The specific embodiment
Fig. 1 shows the process of manufacturing disposal pore-forming hot-wind nonwoven cloth, comprises the steps:
First, fiber is carried out to shredding;
Then, the fiber after shredding is carried out to combing;
Afterwards, fiber 4 good combing is bonded together and is formed the nonwoven fabric of fibre net structure by thermoforming, and on hot-wind nonwoven cloth, punch, make hole when making nonwoven fabric, whole punching hot-wind nonwoven cloth 5 is one-shot forming generation simultaneously;
Finally, the nonwoven fabric of making is cut into required size.
