Description
Technical field
The present invention relates to fill up material and manufacturing approach thereof, particularly pad material of light weight and sound absorption properties and excellent in heat insulating performance etc.
Background technology
In order to realize this pad material; Various trials have been carried out; For example in patent documentation 1; Inorfil, crimpiness inorfil or the anti-flammability organic fiber and the low melting point organic fiber that disclose high-fire resistance carry out mixed cotton equably, and the vehicle that this cotton shape material obtains through heat treatment is used the pad material.
Patent documentation 1: TOHKEMY 2008-291393
Summary of the invention
Yet the sound absorption properties of existing pad material and thermal insulation are all not talkative enough abundant.At this, the objective of the invention is to address the above problem, and light weight is provided and has the excellent sound absorption properties and the pad material and the manufacturing approach thereof of thermal insulation.
To achieve these goals; Pad material of the present invention (mat material) is characterised in that; Mixture by inorfil and core sheath composite fibre constitutes flat substrates, and the melt temperature of the thermoplastic resin of the periphery sheath portion of said core sheath composite fibre is lower than the melt temperature of the thermoplastic resin of central core, and; On the surface at least of flat substrates, the periphery sheath portion that inorfil is melted is fixed.
As above-mentioned inorfil, for example can use glass fibre, preferably using its external diameter is the ramuscule glass fibre of 3 μ m～9 μ m, about 5 μ m most preferably.When using the ramuscule glass fibre, the radical of fiber increases and becomes cellular, and sound absorption properties is improved.
As above-mentioned core sheath composite fibre, the composite fibre and the periphery sheath portion that can use periphery sheath portion, central core to be PETG are polyacrylic composite fibre etc. as the PETG central core.The rugosity of composite fibre is preferably in the scope of 1 dtex～4 dtexs, about 2 dtexs most preferably.
For the mixed proportion of inorfil and core sheath composite fibre, integral body is made as 100% and by percentage to the quality, be preferably set to 20～80 (%): 80～20 (%) most preferably are set at 50 (%): 50 (%).
The manufacturing approach of above-mentioned pad material of the present invention comprises following operation: inorfil is mixed with core sheath composite fibre, and the melt temperature of the thermoplastic resin of the periphery sheath portion of above-mentioned core sheath composite fibre is lower than the melt temperature of the thermoplastic resin of central core; Then blended fiber is dropped into make-up machine and form sheet; The blended fiber of sheet is formed nonwoven fabric sheet through needing machine; Then with nonwoven fabric sheet heating so that the fusion of above-mentioned periphery sheath portion, thereby the pad material of the fixing structure of the above-mentioned periphery sheath portion that obtains that above-mentioned inorfil is melted.
The pad material of said structure is owing to the existence of inorfil improves anti-flammability, and specific heat diminishes simultaneously, and heat insulating ability, thermal insulation also improve.And, particularly through use ramuscule core sheath composite fibre, and inorfil that proportion is different and core sheath composite fibre mixed cotton, can easily convert acoustic energy into heat energy, the result brings into play the good sound absorption performance.If use the fritting fiber type as core sheath composite fibre, then become porous matter shape owing to fibre diameter is inhomogeneous, also can improve sound absorption properties thus.
As stated, according to the present invention, can obtain light weight and have the excellent sound absorption properties and the pad material of thermal insulation.

1A, 1B: make-up machine, 2: glass fibre (inorfil), 3:PET fiber (core sheath composite fibre), 5: needing machine, 6: nonwoven fabric sheet, 7: heating furnace, 8: warm-up mill, 9: chill roll, 10: the pad material.
The specific embodiment
Pad material manufacturing process has been shown among Fig. 1, Fig. 2.Fig. 1 is the operation of preparation nonwoven fabric sheet; Wherein possess 2 air-flows (air-lay) formula make- up machine 1A, 1B, glass fibre (GF) 2 and PETG (PET) core sheath composite fibre (below be called the PET fiber) 3 mass ratioes with 50 (%): 50 (%) are dropped among each make-up machine 1A, the 1B.Be transferred (shown in the arrow following Fig. 1) from the GF2 of hopper 11 inputs and the blended fiber of PET fiber 3 through the 1st conveyer belt 12 in each make-up machine 1A, the 1B, and send in the main body jar 14 with even, the consistent state of width by the 2nd conveyer belt 13 of hypomere.In main body jar 14, be stacked as sheet and carry at the 3rd conveyer belt 15 upper quilt layers by the blended fiber of dividing comb and blowing away.Then, overlapping sheet blended fiber of discharging on the sheet blended fiber of carrying by conveyer belt 41,42 from make-up machine 1A being discharged from from make-up machine 1B, and send into the needing machine 5 of hypomere.With the sheet blended fiber overlapping be two-layer, be because can slow down the local uneven of weight per unit area like this.Tegillum is stacked as two-layer sheet blended fiber and makes to be interweaved between the fiber through needing machine 5 and form nonwoven fabric sheet 6, coils into the cylinder shape then.In addition, can use the cassette make-up machine as make-up machine.
As shown in Figure 2, nonwoven fabric sheet becomes the pad material through heating process.That is, in Fig. 2, nonwoven fabric sheet 6 is drawn out by the cylinder state and the heating furnace 7 through possessing far-infrared heater 71.This through in the process by above-mentioned heater 71 heating, the periphery sheath portion of the PET fiber in the nonwoven fabric sheet 6 is melted, and has formed the pad material of the fixing structure of periphery sheath portion that GF is melted.Make the pad material that comes out from heating furnace 7 pass through warm-up mill 8, thereby suppress its surperficial fine hair, simultaneously the whole thickness of adjustment.Then, adjust final thickness, make pad material 10 coolings of fusion simultaneously, then coil into the cylinder shape through the chill roll 9 of terminal section.
In Fig. 3, represent sound absorption qualities by the pad material of the present invention of above-mentioned operation manufacturing with line x.The weight per unit area of pad material of the present invention is 400g/m
2As shown in Figure 3, (weight per unit area is 477g/m more with the high sound absorption properties materials that adopted in the past
2) (weight per unit area is 415g/m for (line y) or polyester mat
2) (line z) compares, though light weight, in the frequency band of 500Hz～6300Hz, the sound absorption qualities that performance is excellent.
In addition, as shown in Figure 4 for heat-proof quality, pad material of the present invention (line x) and equal weight per unit area (400g/m
2) above-mentioned heat insulation and acoustic absorption pad (line y) compare, specific heat is little in 20 ℃～120 ℃ temperature range, the heat-proof quality that performance is excellent.In addition, the mensuration of specific heat is carried out through DSC (differential scanning calorimetry (DSC)) method of using Perkin Elmer corporate system DSC-7 type.
