Abstract
The invention relates to a composite hot air non-woven fabric manufacturing technology. The composite hot air non-woven fabric manufacturing technology comprises the following steps that (1) plastic particles are melted, and then a mesh long fiber layer is manufactured through air flow drafting spinning; (2) a short fiber layer is manufactured through short fibers; (3) the long fiber layer in the step (1) and the short fiber layer in the step (2) are overlapped, and hot air setting is conducted. Compared with the prior art, the fluffy feature of existing hot air non-woven fabric is taken into consideration in the composite hot air non-woven fabric manufacturing technology, the problems that short fibers of short fiber hot air non-woven fabric erect up and discomfort of the skin is caused are solved, and good comfort is achieved.
Description
[technical field]
The present invention relates to hot-wind nonwoven cloth technical field, relate in particular to a kind of compound hot-wind nonwoven cloth preparation technology.
[background technology]
Hot-wind nonwoven cloth is under the jurisdiction of the one in hot blast adhesion (hot rolling, hot blast) nonwoven fabric, and hot blast nonwoven is after fiber is carded to, and utilizes the hot blast on drying plant to penetrate fibre web, makes it to be heated and is able to the nonwoven fabric of bonding generation.Hot-wind nonwoven cloth has softness and higher fluffy sense, obtains applying more and more widely in hygienic material fields such as baby diaper, sanltary towel and adult-incontinences.Traditional hot-wind nonwoven cloth technique is sampling two-component staple fiber, by following technique:
Fiber opening-> combing-> hot-air oven sizing-> reels and cuts
Prior art as shown in Figure 1, because raw material is staple fibre, after hot air shaping, has fiber to erect, and when the short fiber layers erecting 1 in these west and end user's skin contact, can insert capillary of skin, causes discomfort.
Therefore, be necessary to provide a kind of compound hot-wind nonwoven cloth preparation technology to solve the problems referred to above.
[summary of the invention]
Main purpose of the present invention is to provide one can solve existing hot-wind nonwoven cloth staple fibre and erects problem, takes into account again the compound hot-wind nonwoven cloth preparation technology of the fluffy sense of hot-wind nonwoven cloth uniqueness simultaneously.
The present invention is achieved through the following technical solutions above-mentioned purpose: a kind of compound hot-wind nonwoven cloth preparation technology, it comprises the following steps:
Step 1, will be after plastic pellet melting by the webbed long fiber layer of air drawing spinning system;
Step 2, staple fibre is made to short fiber layers;
Step 3, the short fiber layers in the long fiber layer in step 1 and step 2 is superposeed and carries out hot blast setting.
Compared with prior art, the compound hot-wind nonwoven cloth preparation technology's of the present invention beneficial effect is: the compound hot-wind nonwoven cloth preparation technology of the present invention has taken into account the fluffy sense of existing hot-wind nonwoven cloth, and solved staple fibre hot-wind nonwoven cloth staple fibre and erect, cause the problem of ultimate consumer's skin discomfort.

[detailed description of the invention]
Shown in Fig. 3, a kind of compound hot-wind nonwoven cloth preparation technology of the present invention, a kind of compound hot-wind nonwoven cloth preparation technology, is characterized in that, comprises the following steps:
Step 1, will be after plastic pellet melting by the webbed long fiber layer 2 of air drawing spinning system;
Step 2, staple fibre is made to short fiber layers 1;
Step 3, the long fiber layer in step 12 and the short fiber layers 1 in step 2 are superposeed and carry out heat.
Wherein, step 1 comprises carries out carrying out melt extruded by twin-screw using one or both plastic pellets in PP, PET and PE as raw material, the plastic pellet raw material squeezing out is imitated to silk, then aspirate into net by the drawing-off of air-flow high speed and air-negative-pressure, form long fiber layer 2.
Wherein, step 2 comprises carries out shredding processing by staple fibre, then passes through carding, forms short fiber layers 1, and described staple fibre is two components, and it comprises any two kinds in PP, PET and PE.
Shown in Fig. 2, a kind of compound hot-wind nonwoven cloth, comprise short fiber layers 1 and the long fiber layer 2 of upper and lower superimposion, short fiber layers 1 and the superimposion moulding Shang Xia 2 of long fiber layer, when use, long fiber layer and skin contact, because long fiber layer is the wire side that continuously uninterrupted long fiber is made, so without the sensation of any discomfort, there is good comfortableness, the grammes per square metre scope 7-24 gram that long fibre net is every square metre when contact skin; Number of plies 1-2 layer; The grammes per square metre scope 7-40 gram that web of staple fibers is every square metre; Number of plies 1-2 layer.The advantage of this product comprises that long fiber superficial layer can avoid chafe, has kept fluffy structure, has good comfortableness and wire side brute force, and can better realize the colored type effect of 3 D stereo.Uninterrupted long filament becomes net more to have superiority than existing hot-wind nonwoven cloth on cost, has reduced total production cost of hot-wind nonwoven cloth.
Shown in Fig. 4, a kind of equipment of manufacturing compound hot-wind nonwoven cloth, comprise transport 4, the long fiber that the top of described transport 4 is provided with for long fiber being made to netted long fiber layer successively along throughput direction becomes screen component, becomes screen component and hot blast setting baking oven 30 for staple fibre being made to the staple fibre of short fiber layers.Described long fiber becomes screen component to comprise the melt extruded device 10 connecting successively from top to bottom, imitative silk device 11, drafting system 12 and suction web forming device 13, described staple fibre becomes screen component to comprise the fibre-opening unit having 20 and the carding device 21 that connect successively from top to bottom, plastic pellet pushes by melt extruded device 10, then imitate silk by imitative silk device 11, carrying out the drawing-off of air-flow high speed by drafting system 12, aspirating into net by suction web forming device 13 by air-negative-pressure, form long fiber layer 2, simultaneously, existing staple fibre carries out shredding by fibre-opening unit having 20, then carry out carding by carding device 21, form short fiber layers 1, transport 4 is transported to the short fiber layers preparing 1 and the long fiber layer 2 previously preparing the porch of hot blast setting baking oven 30, and short fiber layers 1 is stacked in to long fiber layer top, send into subsequently hot blast setting baking oven 30 and carry out hot blast setting.
Above-described is only some embodiments of the present invention.For the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, these all belong to protection scope of the present invention.
