Description

Multiplex electric implanted article

Technical field

The present invention relates to a kind of multiplex electric implanted article that pile has been carried out multiple flocking.

Background technology

At present, sit every field such as face, carpet, upholstery material at chair and all use electric implanted article.Use more making by the following method, that is: the base cloth that comprises textile and knit goods or comprise resin sheet and the base material of synthetic resin on apply binder resin, the pile that will comprise fibers such as the nylon fiber that cuts into certain-length and staple fibre again carries out electric flocking.Pile layer is the electric implanted article (to call a heavy implanted article in the following text) of one deck.

In addition, as special electric implanted article, the present known double implanted article that has.For example in real public clear 43-24540 communique, record the electric implanted article of following deerskin style, promptly, 2 kinds are had than after the comprehensive flocking of the pile of long fiber length, further apply binder resin on its surface, the pile flocking of the fibre length that will extremely lack then, thus it has uneven convex-concave surface.

On the other hand, seeking to have higher intention in recent years, and having both the electric implanted article of feeling of high class.For example, wish to obtain the implanted article of feeling of high class, in the pile surface of having carried out comprehensive flocking, the pile of the fibre length by will having same degree repeats flocking, give the heavy implanted article of one unexistent high soft property, and then, give its intention by top layer flocking is become the decorative pattern shape.

Yet, the present double implanted article of fibers such as employed nylon fiber that is used for electric flocking of pile and staple fibre, because the linearity of the pile after the flocking and not good with the up rightness of base material, so have the inadequate problem of the flatness of flocked surface.Also has in the decorative pattern flocking problem in addition by the distinctiveness difference of the formed decorative pattern of flocking (below, claim flocking).The implanted article of the outward appearance grade that can satisfy aspect feeling of high class does not also have so far.

In addition, in the decorative pattern flocking,,, therefore, has the inadequate problem of durability of decorative pattern so that pile collapses and causes decorative pattern to become in long-term the use is not distinct because outside stress focuses on the pile of decorative pattern end easily.In addition, present double implanted article has than a heavy implanted article problem that pile elasticity weakens, damages soft property takes place easily under the situation that is used for flocking face length time load loads such as chair seat face.

PTT fiber that is used for electric flocking purposes and the cloth and silk that has used this fiber are disclosed in the WO99/32695 communique., because this cloth and silk just carries out a heavily flocking with the PTT fiber, so intention and soft property are insufficient sometimes.

Therefore, studying minimizing pile elasticity and weakening, and soft property is good, has the electric implanted article of soft feel again.

Summary of the invention

The objective of the invention is to, a kind of multiplex electric implanted article that pile has been carried out multiple flocking is provided, and its outward appearance grade is good, particularly will top layer flocking becomes the decorative pattern implanted article of decorative pattern shape, the distinctiveness of its flocking, durability and soft property are good, have soft hand feeling.

The inventor has carried out research repeatedly for solving above-mentioned problem, and it found that the fibrous material that is used for the pile portion of multiplex electric implanted article by specific, can realize this purpose, thereby has finished the present invention.

That is, the present invention is as follows:

1. a multiplex electric implanted article has wherein carried out multiple flocking with pile, it is characterized in that, at least a portion of this pile comprises polypropylene terephthalate's fiber.

2. as above-mentioned 1 described multiplex electric implanted article, it is characterized in that flocking comprises polypropylene terephthalate's fiber to the pile of the lower floor except that top layer.

3. as above-mentioned 1 described multiplex electric implanted article, it is characterized in that flocking comprises polypropylene terephthalate's fiber to the pile on top layer.

4. as above-mentioned 3 described multiplex electric implanted articles, it is characterized in that the flocking on top layer is the decorative pattern shape by flocking.

5. as above-mentioned 3 or 4 described multiplex electric implanted articles, it is characterized in that the distillation transfer printing has been carried out on top layer.

Below, describe the present invention in detail.

Multiplex electric implanted article of the present invention is the electric implanted article that pile has been carried out multiple flocking.In the present invention, multiple flocking is meant resin bed and the pile that carried out electric flocking on resin bed made one deck, this layer is accumulated as multiple more than two layers again.For example, so-called double implanted article is meant, is carrying out on the resin bed on the base material on the pile surface of electric flocking, the application of resin layer again, pile is carried out electric flocking in the above then, overlapping again resin bed and pile is triple implanted articles on double implanted article.

Need to prove that so-called orlop is meant the layer that joins with substrate layer, top layer is meant the layer (offside of base material) as the surface of multiple implanted article.

Each pile layer of multiple flocking can be the comprehensive flocking of pile being carried out flocking that covers whole surface roughly the samely, perhaps also can be the decorative pattern flocking that the pile flocking is become the decorative pattern shape.Each pile layer that is multiple flocking can be flocking comprehensively completely, perhaps can be decorative pattern flocking completely, perhaps also can be to mix in each pile layer to have comprehensive flocking and decorative pattern flocking.

For example, by carry out the decorative pattern flocking in the flocking comprehensively stackedly, can make and have the high soft property and the implanted article of intention concurrently.In addition, carry out the decorative pattern flocking, also can make implanted article with higher intention by stacked again in the decorative pattern flocking.Need to prove that so-called in the present invention decorative pattern flocking is meant does not carry out comprehensive flocking with pile but with flocking part and the partially mixed state of non-flocking.

Multiplex electric implanted article of the present invention, form pile layer carrying out at least a portion of pile of flocking must be polypropylene terephthalate's fiber.In each pile layer, the ratio of polypropylene terephthalate's fiber, preferred more than 30% in quality %, more preferably more than 50%, further preferred more than 70%, most preferably more than 80%.The ratio of polypropylene terephthalate's fiber just can fully reach purpose of the present invention if in above-mentioned scope.

In addition, in the whole pile that forms implanted article, the ratio of polypropylene terephthalate's fiber, preferred more than 10% in quality %, more preferably more than 20%, further preferred more than 30%, most preferably more than 40%.

Polypropylene terephthalate's fiber can only be used for undermost pile layer, also can only be used for intermediate layer or top layer, perhaps can be used for orlop and intermediate layer, intermediate layer and top layer.In the pile of whole layer, most preferably use polypropylene terephthalate's fiber.

In the present invention, as the fiber beyond polypropylene terephthalate's fiber, can use desirable various fibers in the scope of not damaging purpose of the present invention, for example the fiber of the gloss difference of pet fiber, cationic dye capable of dyeing pet fiber, polybutylene terephthalate (PBT) fiber, nylon 6 fiber, nylon 66 fiber, polyethylene fibre and these fibers (light, semimat, full-dull etc. are arranged) and section fiber, spun-dyed fibre, ingrain fiber etc.

In multiple implanted article, the flocking grade of undermost pile has bigger influence to the grade of whole implanted article.When the undermost pile of multiple implanted article of the present invention uses polypropylene terephthalate's fiber because the linearity of pile and with the up rightness height of base material, so undermost flocked surface has very good flatness.Consequently, the flatness on the surface of stacked in the above pile layer of carrying out flocking also increases, thereby obtains the good multiple implanted article that has feeling of high class of outward appearance grade.

Because pile uses polypropylene terephthalate's fiber, thereby make the linearity of pile and reason such as the following deduction that uprises with the up rightness of base fabric.

In multiple implanted article, the surface applied binder resin in undermost pile layer carries out electric flocking with pile once more at this resin bed.The more common water emulsion resin of use of binder resin that is used for electric flocking.When using fibers such as nylon fiber and staple fibre as undermost pile, because these fiber water imbibition height, pile expands so fiber absorbs the moisture of the binder resin inside that is coated on the surface, and pile deforms.Its result since originally take place on one's body at bonding resin layer concavo-convex, so also variation of the flatness on the surface of multiple implanted article.

In addition, though do not have bonded residue pile after removing flocking, particularly need to remove fully after undermost pile is carried out flocking, be not adhered to the residue pile on the resin bed.As the method for removing, generally be to crumple the high machine of effect to wash by brush, as liquid-flow dyeing machine, but at this moment be out of shape, so the flatness on pile layer surface reduces owing to pile is subjected to external force.

And, when undermost pile surface applies binder resin, use the method for scraper coating machine, roll coater, roll screen coating machine etc. generally speaking.But the power when at this moment being subjected to application of resin owing to pile layer is out of shape, so the flatness on pile layer surface reduces.

Nylon fiber, staple fibre, pet fiber, since restorative poor to the moment of distortion, so when undermost pile used these fibers, the flatness on pile layer surface reduced.Carry out flocking in the above, the flatness on consequently multiple implanted article surface is variation also.

Relative therewith, when undermost pile uses polypropylene terephthalate's fiber,, do not expand so do not absorb the moisture of binder resin inside because the water imbibition of polypropylene terephthalate's fiber is very little.And, because restorative also good to the moment of distortion, thus the linearity of pile and with the high state of the up rightness of base fabric under, can carry out the flocking on upper strata, thereby the flatness on multiple implanted article surface is also very good.

In addition, multiple implanted article is compared with a heavy implanted article generally speaking, has high soft property, and is opposite, when being used for the situation of flocking face length time load such as chair seat face load, have that the elasticity that pile takes place easily than a heavy implanted article weakens, the impaired problem of soft property.Particularly at undermost pile the phenomenon that this elasticity weakens taking place easily, yet when undermost pile uses polypropylene terephthalate's fiber, just is difficult to that elasticity takes place and weakens phenomenon.And soft durability significantly improves, so preferred.

Secondly, when polypropylene terephthalate's fiber being used for the pile on top layer,, particularly become under the situation of decorative pattern shape, become extremely distinct decorative pattern implanted article, and can keep its distinctiveness for a long time in flocking except that sense of touch becomes very the softness.

For flocking seems distinct, the uniformity of pile length, the linearity of pile and considerable influence is arranged with the up rightness of base fabric.The decorative pattern flocking is by becoming the decorative pattern shape to obtain the flocking of pile electricity on the bonding resin layer of coating, but the pile that has carried out flocking in the end of decorative pattern, just collapses because of very little external force easily or tilts.

When nylon fiber was used for the decorative pattern flocking, the moisture that absorbs binder resin inside owing to pile expanded, and made the pile distortion, pile particularly takes place easily in the end of decorative pattern collapse or tilt.So,, and become the feint implanted article of decorative pattern because the boundary line of decorative pattern flocking part and non-flocking part is fuzzy.

In addition, when pet fiber is used for the decorative pattern flocking, because almost the pile that does not take place because of moisture expands, so the distortion of pile when being not easy to occur in flocking, collapse or tilt.Yet, when on chair seat face etc., using, concentrate on the decorative pattern end easily and carried out on the pile of flocking, so when long-time the use, begin distortion, collapse or tilt from the pile of decorative pattern end owing to act on the external force of pile.Because pet fiber is restorative poor to the pile distortion, the distinctiveness of decorative pattern just slowly loses.

Relative therewith, because the water imbibition of polypropylene terephthalate's fiber is very little, so not because of the moisture that absorbs binder resin inside expands, thereby obtain extremely distinct decorative pattern implanted article.In addition because restorative also good for distortion, so even also be not easy to take place in the end of decorative pattern pile distortion, collapse or tilt, can keep the distinctiveness of decorative pattern for a long time.

In the present invention, so-called polypropylene terephthalate's fiber, be meant with the propylene glycol ester terephthalate unit to be the polyester fiber of main repetitive, the propylene glycol ester terephthalate unit is about 50 moles more than the %, preferred 70 moles more than the %, more preferably 80 moles more than the %, most preferably 90 moles more than the %.Therefore, comprise as the ternary other sour composition and/or the total amount of pure composition about 50 moles below the %, preferred 30 moles below the %, more preferably 20 moles below the %, PTTs in the following scope of 10 moles of % most preferably.

Preferred 0.7～1.5 (dl/g) of the intrinsic viscosity of PTT, more preferably 0.8～1.3 (dl/g).Intrinsic viscosity is high more, can obtain the restorative fiber with excellent more to distortion.

As the preferred characteristics of polypropylene terephthalate's fiber, intensity is 2～5cN/dtex, more preferably 2.5～4.5cN/dtex, 3～4.5cN/dtex most preferably.Percentage elongation is 30～60%, more preferably 35～55%, most preferably 40～55%.Spring rate is following, more preferably 10～30cN/dtex, most preferably 12～28cN/dtex, preferred especially 15～25cN/dtex of 30cN/dtex.The elastic restoration ratio in 10% when elongation is more than 70%, more preferably 80 above %, 90 above %, preferred more than 95% especially most preferably.

PTT is in the presence of catalyst, under appropriate reaction conditions, make terephthalic acid (TPA) or its functional derivatives and propane diols or its functional derivatives in conjunction with and synthetic.In this building-up process, also can add the 3rd composition of one or two or more kinds and become copolyester, in addition, also can be with PETG, polyester beyond the PTTs such as polybutylene terephthalate (PBT), nylon mixes the (containing ratio of the PTT during mixing with PTT, preferred more than 50% in quality %), or by composite spinning (core shift core-sheath-type, parallel type etc.), become manifesting property of the latent crimp polyester fiber that at least one composition is made of PTT.

As the 3rd composition that adds, aliphatic dicarboxylic acid (oxalic acid is for example arranged, adipic acid etc.), alicyclic dicarboxylic acid's (cyclohexane dicarboxylic acid etc.), aromatic dicarboxylic acid (M-phthalic acid, sodiosulfoisophthalic acid etc.), aliphatic alcohol (ethylene glycol, 1, the 2-propane diols, 1, the 4-butanediol, butanediol etc.), alicyclic alcohol (cyclohexanedimethanol etc.), contain aromatic aliphatic alcohol (1,4-two (beta-hydroxy ethyoxyl) benzene etc.), PTMEG (polyethylene glycol, polypropylene glycol etc.), aliphatic hydroxyl carboxylic acid (ω-hydroxycaproic acid etc.), aromatic hydroxy-carboxylic (P-hydroxybenzoic acid etc.) etc.In addition, having compound (benzoic acid etc. or glycerine etc.) that ester more than one or 3 forms property functional group also can use in condensate is actually the scope of wire.

And, also can contain antioxidant, fire retardant, anti-live agent, pigment, fluorescent whitening agent, infrared absorbent, defoamers etc. such as antiseize pastes such as crystallization nucleating agents such as ultra-violet absorbers such as stabilizing agents such as delustering agent, phosphoric acid, hydroxyl benzophenone derivant, talcum, aerosil, hindered phenol derivative such as titanium dioxide.

The polypropylene terephthalate's fiber that uses among the present invention can obtain with the following method.

Obtain long fibre by the following method: soon intrinsic viscosity is polypropylene terephthalate's polymer melt spinning of 0.4～1.9, preferred 0.7～1.2, after coiling speed about dividing with 1500m/ obtained undrawn yarn, method that stretches with about 2～3.5 times coiling speed or the method for directly prolonging (spin-drawing method), the coiling speed of directly carrying out spinning-stretching process were the high speed spinning method (method is batched in rotation) etc. more than 5000m/ divides again.The partially oriented undrawn yarn that perhaps also can use the coiling speed of dividing with above, the preferred 2500～4000m/ of 2000m/ branch to take out and obtain, at this moment, the multiplying power stretching following with the nature stretching ratio obtains long fibre.

The long fibre that obtains can be made continuously bundle and be formed tow, or also the long fibre that once coils into bag can be separated once more easypro, make bundle with reeling frame etc.In addition, also the undrawn yarn of melt spinning can be made bundle, form the tow after-drawing.

Fiber form can be a fiber uniform in the longitudinal direction and that have certain thickness, its section can be: polygonal type, Multiblade, hollow types or unsetting such as circle, triangle, L shaped, T shape, Y shape, W shape, octofoil, flat (flatness is about 1.3～4, and W shape, I shape, dartlike weapon shape, waveform, sugarcoated haws shape, camber, cuboid etc. are arranged), dog bone shape.

The thickness of the polypropylene terephthalate's fibre single thread that uses in the pile is as long as suitably set according to the pile layer of product purpose, multiplex electric implanted article.For example chair is sat face, chair cover, vehicle seat etc., and its flocked surface is 0.2dtex～30dtex, preferably 0.5dtex～20dtex, more preferably 1dtex～10dtex on the top layer of the product that directly contacts with human skin.In addition, on the top layer of the orlop of multiplex electric implanted article and intermediate layer or carpet and slipmat etc. be 0.5dtex～100dtex, preferred 5dtex～80dtex, more preferably 10dtex～60dtex, 20dtex～40dtex most preferably.

For obtaining electric implanted article, use is cut into the formed pile of random length with the above-mentioned tow of hundreds thousand of～millions of dtex, the bundle of drawn yarn.The cut-out machine that is used to cut off can be any of chopper mode (so-called lipper), rotating knife mode (peeler) etc.And, when cutting off, also can adopt to add the wet of water and cut.

The colorize method of pile is unqualified, the method that can adopt that raw material is painted, bundle dyeing, tow dyeing, package dyeing etc. is dyeed before electric flocking; With give the method etc. of color and decorative pattern arbitrarily by after flocking, implementing dyeing, stamp (containing transfer printing) etc.When raw material is painted, by the selected general good pigment of fastness, can the good pile of manufacturing property.When silk or pile dyeing, select the good disperse dyes of fastness to use,, more preferably dye in 100～130 ℃ the dyeing temperature scope at preferred 90～135 ℃.

In addition, the colorize method of pile also can be used the distillation transfer printing.Utilize the distillation transfer printing as can be known, with xeothermic, can obtain having the calico of fine and smooth pattern at short notice.The electric flocked fiber goods that use polyamide-based fiber, carried out the distillation transfer printing because the distinctiveness of the degree of depth of color and pattern is poor, can not be brought into play the pleochromatic problem that is rich in design feature so have.

Yet, when the cloth that comprises polypropylene terephthalate's fiber is distilled transfer printing, can obtain having the calico of distinct pattern.And for example the present invention, the linearity of pile and with the high multiplex electric implanted article of the up rightness of base fabric in, can obtain the better electric flocked fiber goods of the degree of depth of the distinctiveness and the color of pattern.

As the condition of distillation transfer printing, utilize the identical condition of distillation transfer printing with present PETG fibrid.In addition, the distillation transfer printing is carried out under reduced pressure atmosphere than more reaching purpose of the present invention well under the normal pressure, and is therefore preferred.

The distillation transfer printing can also can be the mode of batch processing for continous way.For example, as disperse dyes, preferred azo class, anthraquinone class, nitrodiphenylamine class etc.Pressure during dyeing (vacuum) is generally 266～4000Pa; Temperature is generally 150～220 ℃, preferred 150～200 ℃; Time is generally 10～120 seconds, as long as suitably selected according to the method for making of cloth such as Density.In distillation during transfer printing, preferably multiple implanted article is carried out heat setting in advance and deposit, so that thermal contraction does not take place in it, the deviation of the decorative pattern that do not occur printing and dyeing.As heat-setting condition, the transfer printing condition (temperature and time) of can considering to distil is suitably selected.

In order to improve the intention of multiple implanted article, also can by mixing, make the color of mixing with carried out the pile of dyeing with different colors with any amount, arbitrary proportion.Or use by pet fiber and cationic dye capable of dyeing pet fiber are merged, carry out poststaining, can obtain utilizing heterochromatic effect with the dyeability difference of polypropylene terephthalate's fiber.In addition, by changing the length of pile, can obtain having the design effect of striped cloth style.

And then, also can make multiple implanted article with anti-charging property by using conducting fibre to carry out flocking in the lump.

In the present invention, good for the separation property that makes pile, ascending to heaven property, the fiber that is used for electric flocking is preferably implemented electrodeposition process.As the employed medicine of electrodeposition process, as long as following medicine suitably is used, i.e. organosilicons such as surfactants such as inorganic salts such as sodium chloride, potassium chloride, barium chloride, magnesium chloride, ammonium chloride, sodium sulphate, magnesium sulfate, ammonium sulfate, sodium metasilicate, potassium silicate, sodium carbonate, sodium sulphate, anion active agent, tween, amphoteric surfactant, Ludox.

Be used for pile is adhered to binder resin on the base material, can suitably select according to the purposes of multiple implanted article, for example can from following material, select arbitrarily: polyvinyl acetate, synthetic rubber latex, natural rubber latex, acrylic acid ester emulsion, polyurethane resin, mylar, vinyl chloride etc.In addition, also these mixed with resin can be used.The coating amount of binder resin according to concentration, the viscosity of binder resin, applies in that multiple implanted article is satisfied in the scope of necessary performance.For example at 150～500g/m ²Scope in, can select coating amount arbitrarily, preferred 200～400g/m ²

Binder resin has no particular limits the coating method of base material, as long as adopt the method for scraper coating machine, roll coater, roll screen coating machine etc.When carrying out the decorative pattern flocking, use the roll screen coating machine, binder resin can be applied as desirable decorative pattern shape, carry out electric flocking.

The base material of using as flocking has no particular limits, and can use cloth such as nonwoven, fabric, braid, or resin film, synthetic resin, metal etc.Raw material also have no particular limits, and can use cloth such as polyester fiber, polyamide-based fiber, polypropylene fibre, cellulose fibre, acrylic fiber as cloth.When being used for blanket such as carpet, because the dimensionally stable of base fabric, so also can paste the glass fibre woven scrim.And, also foaming raw material (vinyl chloride etc.) can be filmed or are pressed into glued board.In addition, for the convenience of the construction of carpet, also can make ceramic tile carpet by the certain size cutting.

The length of pile can and use the thickness of pile to select random length according to product purpose.Preferred 0.2～20mm, more preferably 1～15mm, preferred especially 1～10mm, 1～5mm most preferably.

The density of flocking, the preferred 50～1000g/m of each layer pile layer ², more preferably 60～600g/m ², preferred especially 80～300g/m ²As the not enough 50g/m of flocking density ²The time, sometimes as the desired property deficiency attractive in appearance and soft of multiplex electric implanted article.In addition, surpass 1000g/m when density ²The time, feel is hardened, or pile links and the contact pole plate when flocking, so-called electric spark takes place sometimes make electric flocking difficulty.

In the electricity flocking processing, make to produce high-tension static electric field between electrode of opposite, dispose the base material that is coated with binder resin, make the pile that has carried out electrodeposition process charged, make pile fly to base material and carry out flocking from the opposite side electrode an electrode side.

The method that pile is flown has method (pile being flown from bottom to top and the method for flocking) that (a) downward method (pile being flown from the top down and the method for flocking), (b) make progress etc., adopts downward method more, but is not limited to these methods.

Electrode gap changes according to the length of pile.The length of pile reduces electrode gap in short-term; When pile length is long, increase electrode gap.For example, when pile length is 0.5mm, more than the preferred 50mm of electrode gap; When pile length is 3mm, more than the preferred 200mm of electrode gap.If electrode gap is enough big with respect to the length of pile, it is big that the flying distance of pile just becomes, and can be anchored on the darker position of bonding resin layer, and institute is so that the bonding strength raising of pile.Be applied to the voltage on the electrode,, set arbitrarily in the scope about 10～100KV according to electrode gap, pile length, flocking density, electrodeposition process condition etc.In addition, base material is moved up and down, so that pile is anchored on the bonding resin layer more firmly.

After the flocking, fully bonding in order to make pile, carry out binder resin drying, be used to carry out the heat treatment of cross-linking reaction.Heat treatment temperature is so long as carry out just passable in the temperature and time of the kind of kind that is fit to binder resin and crosslinking agent.After the heat treatment, do not have bonding remaining pile, preferably use air-breathing, brush or overflow dyeing machine etc. to wash processing for removing.

Multiplex electric implanted article of the present invention can be made by the number of times that above-mentioned electric flocking operation is carried out defined repeatedly.Particularly in the flocking in orlop and intermediate layer, the bonding strength in order not make when bonding in the above reduces, and preferably remaining pile is thoroughly removed.
