Description
Technical field
The present invention relates to the technical fields of nonwoven production technological improvement, are bonded in particular to a kind of high-pressure hot wind
The preparation method of non-woven fabrics.
Background technology
Non-woven fabrics is thermally bonded, and can usually be passed through by hot blast adhesion and hot calendering bonding book kind mode, hot rolling mode
The graining roll of heating easily makes fiber net surface quick-binding online, and production line is short, but since fiber net surface is by roll crown
Extruding, obtained non-woven fabrics bulkiness is poor；And hot blast adhesion, it is penetrated using hot wind, has the characteristics that bulk softness, to increase
Add Liquid Penetrant and comfortable feel, often road also needs to carry out punching processing after non-woven fabrics, and production procedure is longer, and process is multiple
Miscellaneous, time cost is relatively high.
It can be seen that two kinds of heat bonding means of hot wind and hot rolling, respectively there is its advantage and disadvantage.How a kind of new technical side is developed
Two kinds of technologies of the higher hot rolling of production efficiency and the preferable hot wind of bulk performance are combined, can promote hygienic use well by case
Product material high-quality and high-efficiency develops.
Invention content
In conjunction with the advantages of the two kinds of heat bondings of hot wind and hot rolling, the present invention provides a kind of preparation of high-pressure hot wind bonding non-woven fabrics
Method, to realize above-mentioned purpose.
Institute's technical solution that uses of the invention for：
Shredding is carried out using low melting point two-component staple fiber, fiber net surface is combed into through carding machine, passes through high-pressure hot wind roller
It is thermally bonded into hot-wind nonwoven cloth.
Preferably, the low melting point two-component staple fiber is core-sheath composite structure, can be with one heart or eccentric；Sheath component
Fusing point is more than 100 DEG C and less than 160 DEG C, and sandwich layer congruent melting point is more than cortex fusing point, and the two differs 20 DEG C or more, sheath component
It is preferred that polyethylene (PE), the preferred polypropylene of sandwich layer ingredient (PP) or polyethylene terephthalate (PET), middle short fiber
Length is 20-60mm, preferably 38mm, 45mm and 51mm.
Preferably, the high-pressure hot wind roller is made of a pair of of surface the metallic roll of ridge design, inside one of roller
For high-pressure hot air, another roller is negative-pressure ward, has hole correspondence between two rollers, to realize penetrating for hot-air.
Preferably, the hole between the ridge design and roller of the high-pressure hot wind roller, different designs combination, can be with shape
At the various pattern structures of non-woven fabrics.
The present invention uses high-pressure hot wind roller, and non-woven fabrics is penetrated the non-woven fabrics for bonding, obtaining using high-pressure hot air
Have many advantages, such as perforated non-woven fabric, has that equipment is simple, technological process is simple.

Specific implementation mode
With reference to embodiment, the present invention is further described.Following embodiments are illustrative, are not restrictive,
Protection scope of the present invention cannot be limited with following embodiments.
As shown in Figure 1, the present invention institute process scheme that uses for：Shredding is carried out using low melting point two-component staple fiber,
It is combed into fiber net surface through carding machine, hot-wind nonwoven cloth is thermally bonded by high-pressure hot wind roller.
Preferential, low melting point two-component staple fiber structure fiber cross section signal as shown in Figure 2 and Figure 3, bi-component
Staple fiber is core-sheath composite structure, can be with one heart or eccentric；The fusing point of sheath component be more than 100 DEG C and be less than 160 DEG C, sandwich layer at
Fusing point is divided to be more than cortex fusing point, the two differs 20 DEG C or more.The preferred polyethylene of sheath component (PE), sandwich layer ingredient preferably poly- third
Alkene (PP) or polyethylene terephthalate (PET).The length of its middle short fiber is 20~60mm, preferably 38mm, 45mm
And 51mm.
Preferably, the high-pressure hot wind roller, as shown in figure 4, be made of the metallic roll of ridge design a pair of of surface, wherein
It is high-pressure hot air inside one roller, another roller is negative-pressure ward, has hole correspondence between two rollers, to realize hot-air
It penetrates.
Preferably, the hole between the ridge design and roller of the high-pressure hot wind roller, different designs combination, can be with shape
At the various pattern structures of non-woven fabrics.
