Background technology
The inside skin material of automobile is mainly by plastic sheet, textile fabric and bondedfibre fabric manufacturing.Plastic sheet has excellent mouldability, but lacks sense of touch.In addition, textile fabric has magnificent outward appearance and owing to the excellent mouldability of low modulus, but textile fabric is expensive because they since little thickness must use by lamination PU foam on its back side.In order to address these problems, bondedfibre fabric has been developed and has been used for the internal material of automobile.
Bondedfibre fabric is a fibrid, they are prepared as follows: pass through carding method, replace using graticule such as cloth, sprawl the fiber of regular thickness and length thin and widely, fiber in several layers of lamination subsequently, and by physical bond, for example acupuncture or water tangle, or for example apply by chemical method, with the layer combination of described lamination.Therefore, bondedfibre fabric is widely used for by the automotive interior material of mould with the regular shape molding, has good productivity ratio with low-cost because they are compared with textile fabric, and has excellent percentage elongation in all directions.This kind bondedfibre fabric that is used for the automotive interior material is usually by needle point method or the manufacturing of water entanglement method.In addition, bondedfibre fabric current at described bondedfibre fabric the surface or the back side on coated with adhesive use after functional to give, or the printshop needs pattern or color so that the use outward appearance variation after on the surface of described bondedfibre fabric.
Yet bondedfibre fabric is compared sense of touch with textile fabric good, but outward appearance is relatively poor.Contrast, if modulus so that mouldability deterioration are then improved significantly to improve its outward appearance in the surface of processing bondedfibre fabric.Therefore, bondedfibre fabric needing to be not suitable for the automotive interior material of various outward appearances and excellent mouldability.In addition, along with the actuating speed of automobile becomes more and more faster owing to the improvement of automobile engine, the sound absorbing capabilities that must improve internal material is to be provided at comfortable driving environment during the scorch, if sound absorbing capabilities is lowered but bondedfibre fabric has smooth surface as most of inner skin materiaies.
Simultaneously, proposed on textile fabric, to form various method of patterning, but it only can reach (referring to Korean patent registration No. 10-0771071) by the etching method that uses laser-induced thermal etching equipment by lithographic method.Yet, use alkaline solution, for example the wet etch method of NaOH is simple, quick and is easy to control processing.In addition, employed equipment and chemicals be at a low price and it can be used for extensive work helpfully.Therefore, still need to obtain the method that various outward appearances are used wet etch method simultaneously in this area.
Summary of the invention
In order to satisfy this kind needs, the present inventor carries out preprocess method by being independent of etching process ground, for example apply or the printing bondedfibre fabric, forming various outward appearances, and made have various outward appearances, the automotive interior skin material of good ABRASION RESISTANCE and good mouldability.In addition, after this kind preprocess method, the alkali etching on bondedfibre fabric has improved the sound absorbing capabilities of automotive interior material significantly subsequently.
The present invention will solve foregoing problems, and the method for making the bondedfibre fabric be used for the automotive interior material is provided, for example coating or printing process are carried out together with carry out various preprocess methods on nonwoven surface by carry out the alkali etching method with regular shape for they.Thereby the present invention can provide the bondedfibre fabric with improved ABRASION RESISTANCE and outward appearance and improved mouldability and sound absorbing capabilities.
In order to achieve the above object, the invention provides the method for following manufacturing bondedfibre fabric:, on the surface of described bondedfibre fabric, carry out the alkali etching method then and carry out by the surface or the back side of printing bondedfibre fabric.
According to described method, preferably before described printing process, apply the surface or the back side of described bondedfibre fabric.
According to described method, more preferably after printing process, painting method or their combination, repeatedly carry out the alkali etching of bondedfibre fabric.
According to described method, preferred bondedfibre fabric comprises more than 2 and more than 5 fibrages.
According to described method, carry out painting method by using binding agent, described binding agent comprises and is selected from least a in acrylic acid series, styrene, polyvinyl chloride, polyvinyl alcohol, polyester, ethylene-vinyl chloride, ethane-acetic acid ethyenyl ester and the polyurethane.
According to described method, preferably carry out the alkali etching method more than 50% to being less than 90% for the surface area of bondedfibre fabric.
According to described method, preferably be selected from any of NaOH, KOH, RbOH and CsOH by use, more preferably, carry out the alkali etching method by using NaOH.
According to described method, the fibrage of preferred bondedfibre fabric comprises the polyester of 50-100wt%.
In addition, the invention provides the bondedfibre fabric that is used for the automotive interior material by described method manufacturing.
To at length set forth the present invention below.
The present invention relates to be used for the manufacture method of the bondedfibre fabric of automotive interior material, it is characterized in that on the surface of described bondedfibre fabric, carrying out the alkali etching method by required pattern, so that the color of described bondedfibre fabric through etching and processing itself can manifest and print the surface or the back side of described bondedfibre fabric before engraving method.
The surface that described engraving method is used for making fiber is by the regular pattern fusion, so that unique three-dimensional appearance can manifest.Because make of shape and the degree of depth fusion of the surface of fiber with overbased materials, so engraving method is suitable for and approaches textile fabric and compare the bondedfibre fabric with thick fiber layer by rule.In addition, because textile fabric is woven with graticule, thus during engraving method, cut warp or parallel, and therefore, reduce the intensity of textile fabric significantly.Yet because twine bondedfibre fabrics with many fibre bundles, even its any part is because method is compromised, TENSILE STRENGTH and abrasion resistance be deterioration seriously not.Therefore, engraving method is the method that is fit to of making bondedfibre fabric.
The present invention uses basic matterial to be used for engraving method and forms three-D pattern with the shape and the degree of depth by rule on the surface of bondedfibre fabric, so that on the surface of bondedfibre fabric, form three-dimensional structure, compare sound absorbing capabilities with the bondedfibre fabric of same weight thus and improved significantly.In addition, the melt surface that makes bondedfibre fabric by the shape and the degree of depth of rule to be reducing the high tensile elongation and the modulus of bondedfibre fabric significantly, thereby improves the mouldability of bondedfibre fabric.
Yet, if only carry out engraving method, because the regular pattern that forms by the melt surface that makes fiber shows the color identical with bondedfibre fabric, so be difficult to obtain different shape.Therefore,, before engraving method, obtain various outward appearances, and obtain bigger diversity by the painting method that before printing process, adds by carrying out printing process in order to address this problem.In addition, when adding coat or printed layers, improved abrasion resistance and DIMENSIONAL STABILITY, and along with surface area increases, sound absorbing capabilities is improved by this kind preprocess method.Fig. 6 shows the example that obtains by the combination of carrying out various preprocess methods.
The present invention forms the fibrolaminar bondedfibre fabric with at least two different colours, so that these different colours can appear on the corresponding fibrage by mode in succession, thereby obtains the bondedfibre fabric that is used for internal material with various patterns and color.
Bondedfibre fabric is a fibrid, it is not by graticule such as cloth weaving, be prepared as follows but change into: sprawl the fiber of regular thickness and length by carding method thin and widely, subsequently by net width of cloth make-up machine by required weight and width lamination fiber in succession in several layers.Therefore, obtain the fibrage that has different colours more than five, so cause excessive cost of investment and therefore it is infeasible economically because must install more than five carding machines and net width of cloth make-up machine.Therefore, preferred described fibrage is more than two layers and be less than five layers.
Printing or painting method can carry out as preprocess method before engraving method.Can on the surface of bondedfibre fabric or the back side, print or painting method, carry out separately or with its combination.Printing process is meant the surface with required pattern or color printing bondedfibre fabric.Can carry out printing process by changeing screen method, plansifter method or hectograph method.In addition, if also carried out painting method before printing process, then compare with only carrying out printing process, the shades of colour of the color by allowing to be different from bondedfibre fabric itself manifests and can obtain more diverse outward appearance.
Favourable effect is as follows:
The present invention print at short notice with painting method at least twice on the surface of bondedfibre fabric, forming various patterns by low cost, thereby give 3-D effect and improve design performance.Because this kind preprocess method, the present invention improves ABRASION RESISTANCE, obtains various outward appearances, improves tensile elongation by engraving method, and improves mouldability significantly by reducing modulus.Therefore, the invention solves conventional coating of the prior art or printing process by forming the problem that various outward appearances reduce mouldability.In addition, the present invention improves the surface area of bondedfibre fabric to improve sound absorbing capabilities significantly by engraving method.In other words, obtain these various outward appearances by printing or painting method, and reach physical property by engraving method, for example improvement of sound absorbing capabilities and mouldability.Therefore, the present invention can be provided for the recent bondedfibre fabric of the needed various functions of automotive interior skin material that is of having of automotive interior material.

Utilize exemplary embodiment to describe the present invention in detail below, but described embodiment is illustrative purely, should not be construed as limiting the invention scope.
The bondedfibre fabric that is used for internal material according to the present invention for example prints or painting method and engraving method manufacturing by preprocess method.
The specific embodiment
Embodiment 1: painting method
The method that chemistry of the present invention applies (or adhesive coated) is shown among Fig. 9.
Coating equipment comprises a pair of roller, and can apply one or two surface of bondedfibre fabric by at least one coating equipment.If bondedfibre fabric passes through between this pair of rollers of rotating in opposite direction based on central shaft, then binding agent is added on the surface that a roller and bondedfibre fabric be adjacent to each other, with this surface of the adhesive coated bondedfibre fabric of applying.Can be used as binding agent from ACRYSOL 890, Acrylic Emulsion DK-6800 DK Chem or the EW-100S SKI PETRESIN that DKC obtains.
At this moment, the surface of the bondedfibre fabric of two rollers of contact can identical (front surface coatings), or can difference (back side coating).In addition, front surface applies and the back side applies if carry out simultaneously, and then the duplex surface coating is possible.That is, can followingly carry out duplex surface and apply: carry out the back side by a pair of roller and apply, the dry back side through applying is carried out front surface by another pair of rollers to the bondedfibre fabric of drying and is applied, and dry once more bondedfibre fabric.In other words, carry out so that the back side applies so that bondedfibre fabric by first roller, the apparent surface on the surface adjacent with first roller is by second roller, and introduces binding agent between described second roller and the surface adjacent with bondedfibre fabric.Foam adhesive is 50-500g/l, and coated weight is 5-50gsm, and the scale distance between two rollers of coating equipment is 0T-5T.
Embodiment 2: printing process
Use the printing process of changeing screen method to use the printing element (Figure 10) of its transfer sieve contact deflector roll.Along with commentaries on classics sieve roller (a) and deflector roll (b in Figure 10) between the passing through in Figure 10 of bondedfibre fabric in the first color printing unit, extruded by pushing rod (d among Figure 10) by being installed in the color binding agent (e among Figure 10) that changes binding agent supply (c among Figure 10) emptying in the sieve roller, make its part discharge, on nonwoven surface, form pattern thus from the outer surface that changes sieve.Because the extruding rod is arranged in the magnetic field range of magnet (electromagnet) (f among Figure 10), thus the outside of sieving changeed by the excellent color binding agent of extruding to this by precalculated position discharging scheduled volume, thus allow printing.At this moment, can control the resolution ratio of printed article pattern by the magnetic field intensity of regulating magnet to 3-8kgf.If the magnetic field intensity height of magnet, then pattern is dark and clearly, and if its magnetic field intensity low, then pattern is fuzzy printing.
Also printing element (the second color printing unit) with described printing element same type is installed in this side, and if bondedfibre fabric by the first color printing unit and then move to the second color printing unit, then form additional pattern.Thereby, obtain different outward appearances via at least twice in succession processing, and mix and bondedfibre fabric is adopted the required color printing by binding agent and quantity are counted the dyestuff of 1-10wt% and inorganic pigment with respect to the gross weight of binding agent.For described dyestuff, use Foron Black RD-3G 300 (can obtain) or Foron Dark Blue RD-2RE 300 (can obtain) from the Clariant of Switzerland from the Clariant of Switzerland, and for described inorganic pigment, use RYUDYE-W BLACK RS CONE, RYUDYE-W NAVYBLUE FFTR, RYUDYE-W RED FFGR, RYUDYE-W YELLOW FF3R or RYUDYE-WBROWN FFR (by DIC, Japan makes).
Deflector roll is by soft material, and for example rubber or silicon form, so that reduces the thickness deviation of bondedfibre fabric, prints the surface of bondedfibre fabric whereby by the thickness of rule.In addition, wherein printing mesh screen is the long-pending about 40-90% of nonwoven surface by the escape of the open consequently binding agent of regular pattern with the open zone that is printed.
The dyestuff that will be fine powder form by dispersant is dispersed in the water with the preparation disperse dyes by colloidal state basically, and this dyestuff is dissolved in the fiber for the treatment of to dye on fiber.
As above-mentioned, via at least twice in succession printing process, bondedfibre fabric is printed different pattern and color according to the mixing ratio of dyestuff and pigment, obtain various outward appearances thus.
Embodiment 3: alkali etching method
On the surface of the bondedfibre fabric that forms by the 100wt% polyester, carry out the alkali etching method.By on the surface of fiber, adding overbased materials NaOH so that fiber carries out the alkali etching method by the shape and the degree of depth fusion of rule.After surface, the puddle of printing solutions and bondedfibre fabric is separated with basic matterial printing bondedfibre fabric.
Measure the mouldability and the sound absorbing capabilities of the bondedfibre fabric of as above making that is used for internal material.Embodiment 4: the contrast of mouldability
In order to confirm of the influence of alkali etching method, compare before engraving method and modulus afterwards to the mouldability of bondedfibre fabric.
Table 1
In the table 1, term " 25% modulus " is an important physical properties of estimating mouldability in the above, and it is to instigate the bondedfibre fabric of predetermined length to extend 25% desired power.Therefore, this value is low more, and mouldability is good more.Shown in top table 1, the modulus of bondedfibre fabric is markedly inferior to before the engraving method after engraving method.Specifically, longitudinal modulus reduces by 30% before than engraving method.
Embodiment 5: the contrast of sound absorbing capabilities
In order to verify the influence of engraving method, before engraving method and afterwards relatively for the sound absorbing capabilities of each frequency bandwidth to the sound absorbing capabilities of bondedfibre fabric.It is excellent that the sound absorbing capabilities of the bondedfibre fabric of etching and processing is compared in all frequency bandwidths with engraving method before, and special confirmation, and sound absorbing capabilities is improved (Figure 11) significantly in greater than the frequency bandwidth of 1000Hz.
