Description
Technical field
The present invention relates to manufacture method and the square carpet of square carpet (tilecarpet).
Background technology
All the time, be everlasting office building, commercial facility, mansion etc. ground on lay square carpet.
Square carpet is formed as the rectangular shape (square etc. of such as 500mm × 500mm) specified usually.
The square carpet of aforementioned rectangular is laid on the ground by making to be close between the edge of the square carpet adjoined.
As the paving mode of this square carpet, there will be a known the mode of laying multiple square carpet with the form that the tufting direction of the pile yarns (pileyarn) of adjacent square carpet is perpendicular, mode etc. that the form paralleled with the tufting direction of the pile yarns of adjacent square carpet lays multiple square carpet.Below, front a kind of paving mode is called " checkering (quarterturn) mode ", rear a kind of paving mode is called " full slice system (monolithic) mode ".
Aforementioned checkering mode owing to being lay square carpet with the form that the tufting direction of adjacent square carpet is perpendicular, therefore, for the people seeing ground entirety, can the FINAL APPEARANCE of provider's grid pattern.
Aforementioned full slice system mode, owing to being be that unidirectional form lays square carpet with the tufting direction of adjacent square carpet, therefore, for the people seeing ground entirety, can provide the FINAL APPEARANCE as same blanket en bloc.
But, when laying existing square carpet on the ground according to aforementioned full slice system mode, when looking around ground entirety, there is the easy noticeable problem of a part in multiple square carpet.
If a part of square carpet is noticeable, then beholder easily recognizes it and is made up of multiple square carpet.Therefore, be difficult to beholder be provided as the feature of full slice system mode as the FINAL APPEARANCE having laid a monoblock carpet.
As the noticeable reason of situation next part square carpet in this full slice system mode, think there is following reason.
Specifically, square carpet manufactures via following operation usually: multiplely knit the doubling of after stain dyed yarn by different for dyeability, is interweaved or twists thus prepare the preparatory process of multiple pile yarns; Many are comprised the tufting operation of tufting on the aforementioned multiple pile yarns knitting after stain dyed yarn are arranged in Rack strip base fabric according to required pattern; With the dyeing process of respectively knitting poststaining dyeing yarn of dyestuff by these each pile yarns; Base fabric after dyeing carries out backing (backing) operation of substrate processing with resins such as PVC; By implement substrate processing base fabric be cut into regulation shape, obtain square carpet cut operation.Usually, aforementioned base fabric uses the base fabric of length of side several times that width is square carpet (such as 4 times etc.), makes it possible to cut out polylith square carpet in its width direction.And, form aforementioned pile yarns by the multiple after stain dyed yarn of knitting different by dyeability, the square carpet of variegated tune can be obtained.
Below, sometimes the structure comprising the pile yarns knitting after stain dyed yarn there is is to be called " grey cloth " tufting on base fabric obtained in aforementioned tufting operation.
As the decoration method in aforementioned dyeing process, general use winch dyeing method (winchdyeing) or continuous dyeing method.
Winch dyeing method is the representative method of batch (-type) colouring method, it is that the strip grey cloth of Rack is cut into specific length, the grey cloth of this specific length is formed ring-type, while make the grey cloth of this ring-type flood in the staining bath filling dyestuff, rotate, while will the method for poststaining dyeing yarn be knitted.It should be noted that, because winch dyeing method is that limit makes grey cloth in the method for staining bath inner suspension Edge Coloring, be therefore not suitable for the dyeing that bath raio (bathratio) is little.
Continuous dyeing method be limit by the strip grey cloth of Rack to longitudinal downstream continus convergence, while dye-coating will be knitted the method for poststaining dyeing yarn on pile yarns, by this dyestuff.Continuous dyeing method, owing to carrying out whole dyeing process serially, is therefore called " continuous dyeing ".The equipment implementing continuous dyeing method be generally by independently carrying out that dyestuff provides, steaming process, washing, liquid provide, a succession of connection of specific mechanical of drying etc., this equipment can carry out the initial period of dyeing process consistently to final stage, is therefore suitable for a large amount of grey cloth that dyes.
Aforementioned continuous dyeing method due to can continuously dyed gray knit after stain dyed yarn, therefore, the short time can manufacture square carpet.That is, continuous dyeing method has excellent productivity ratio.
But aforementioned continuous dyeing method is difficult to the concentration of the dyestuff of grey cloth width to be adjusted to evenly.Therefore, when being cut by the grey cloth after dyeing and obtain polylith square carpet, the pile yarns of each square carpet that the width of grey cloth cuts out produce aberration, easily so-called " stain " occur.
Like this, the polylith square carpet cut out from the grey cloth that stain occurs has delicate difference each other on dyeability, and therefore, when being laid by full slice system mode, a part of square carpet is easily noticeable.
Patent Document 1 discloses following method for making: manufacture the different multiple curl yarn (curlyarn) of dyeability in advance, therefrom select any two kinds of curl yarns, combine and carry out interleaving treatment or twist thread processing thus obtaining many two color yarns, therefrom select any 2 two color yarns, by these 2 two color yarns with adjacent form tufting on base fabric, then, the carpet of how variegated tune is manufactured by dyeing process.
Describe in patent document 1, according to described method for making, tone complexity can be obtained, there is contrast and there is the carpet of the how variegated tune of feeling of high class.
But, in patent document 1, for when looking around polylith square carpet entirety when laying polylith square carpet in full slice system mode, the noticeable problem of a part of square carpet and solution thereof, completely open or enlightenment.

Preferably, respectively to knit the region of each pile yarns of form tufting of the weight ratio equalization of after stain dyed yarn throughout whole base fabric.
Herein, in table 2, illustrate that the 1st shown in the above-mentioned table 1 of use is to the 7th yarn, made respectively to knit the various arrangements examples that after stain dyed yarn arranges with the form of equalization.The weight of respectively knitting after stain dyed yarn is 1 weight portion.
It should be noted that, except the arrangement example shown in this table 2, can certainly arrange respectively knitting after stain dyed yarn with the form of equalization.
［ table 2 ］
In table 2, respectively, A represents the 1st yarn of table 1, and B represents the 2nd yarn of table 1, and C represents the 3rd yarn of table 1, and D represents the 4th yarn of table 1, and E represents the 5th yarn of table 1, and F represents the 6th yarn of table 1, and G represents the 7th yarn of table 1.
In table 2, such as, routine AA is arranged ... represent tufting have the repeat region of multiple 1st yarn, the repetitive in this region to be A and this repetitive A space direction is repeated multiple.
Similarly, routine BCBC is arranged ... represent that alternately tufting has the repeat region of the 2nd yarn and the 3rd yarn, the repetitive in this region be BC and this repetitive BC space direction is repeated multiple.
Similarly, routine DAEADAEA is arranged ... represent that tufting has the repeat region of the 4th yarn, the 1st yarn, the 5th yarn and the 1st yarn in order, the repetitive in this region be DAEA and this repetitive DAEA space direction is repeated multiple.
Repetitive in the present invention refers to that repeat region refers to the region that this repetitive repeats by the unit of the pile yarns tufting of optional 1 or more than 2.
By by each pile yarns tufting on base fabric, base fabric forms the repeat region be selected from by 1 in the repeat region that these repetitives are formed or more than 2.
The configuration of aforementioned various repeat region is not particularly limited, can suitably designs.
In the present invention, preferably, every block square carpet arranges luminance difference in the multiple region repeat region more than required all independently, and these repeat regions are configured adjacently.When laying this square carpet in full slice system mode, the seam of adjacent square carpet is not easily noticeable.
Especially, preferred square carpet is, arranges luminance difference in the multiple region repeat region more than required independently, becomes large mode configure aforementioned each region with the luminance difference between 2 adjacent repeat regions.This square carpet not only can recognize the luminance difference in repeat region, and can recognize the luminance difference between adjacent repeat region, and therefore, when laying by full slice system mode, the seam of adjacent square carpet is not easily noticeable.
Specifically, when laying square carpet, seam is noticeable is because the part of this seam creates a little luminance difference.As mentioned above, in 1 piece of square carpet, owing to existing compared with the luminance difference (there is in any one repeat region required above luminance difference) under small field of view with compared with the luminance difference (there is between 2 adjacent arbitrarily repeat regions required above luminance difference) under Large visual angle, thus when looking around the ground entirety of laying square carpet in full slice system mode, the luminance difference of seam is submerged in their luminance difference, as a result, seam is not easily noticeable.
Luminance difference in aforementioned repeat region is preferably more than 2.0, is more preferably more than 3.0.Luminance difference lower than 2.0 time, the luminance difference in repeat region becomes not easily noticeable.Luminance difference in repeat region is larger, and luminance difference is more obvious, but time too obviously, be also not preferred sometimes in design, therefore, the luminance difference in aforementioned repeat region is preferably less than 6.0.
In addition, as long as every block square carpet arranges the repeat region that at least one has the luminance difference of aforementioned range.But, when the repeat region of the luminance difference too much with aforementioned range is set, sometimes the luminance difference between being difficult to adjacent repeat region is set in aftermentioned scope, therefore, every block square carpet preferably arranges 2 ~ 8 independently, more preferably arranges the repeat region that 3 ~ 5 have the luminance difference of aforementioned range independently.
In repeat region, as long as there is the combination of the large pile yarns of at least 1 group luminance difference.
On the other hand, the luminance difference between aforementioned 2 adjacent repeat regions is preferably more than 2.0, is more preferably more than 3.0.Luminance difference lower than 2.0 time, the luminance difference between repeat region becomes not easily noticeable.Luminance difference between adjacent repeat region is larger, and luminance difference is more obvious, but time too obviously, be also not preferred sometimes in design, therefore, the luminance difference between aforementioned adjacent repeat region is preferably less than 6.0.
In addition, as long as the luminance difference place between the adjacent repeat region of every block square carpet with aforementioned range arranges at least 1 place.But, have between adjacent repeat region the luminance difference place of aforementioned range too much time, make seam be not easy noticeable decreased effectiveness, therefore, the luminance difference place between the adjacent repeat region of every block square carpet with aforementioned range is preferably 2 place ~ 8 places, is more preferably 3 place ~ 5 places.
Luminance difference in aforementioned repeat region can be measured by colorimeter according to JISZ8722.Specifically, with reference to the determination step of following embodiment.
Luminance difference between aforementioned adjacent repeat region can be obtained by the luminance difference in 2 adjacent repeat regions being subtracted each other.

Specifically, by not having the random alignment of specific rule by the 2nd yarn, the 3rd yarn and the 4th yarn tufting thus obtaining grey cloth.A part for this random alignment is expressed as: BCBBDCBCBDBCDDBCCBDDBCBCBDBCBDBCBDDBBDCBBDCBCDBCBCBDCBCD DCBCDDBDBBCDBB ... (B:C:D(mass ratio)=3:2:2).Wherein, aforementioned B represents the 2nd yarn, and C represents the 3rd yarn, and D represents the 4th yarn.
Afterwards, similarly to Example 1, by this piece dyeing finishing, back sheet is formed, thus the square carpet of comparison example.
［ evaluation ］
20 pieces are selected arbitrarily separately, respectively their matte of visualization in the square carpet obtained from embodiment 1 and 2 and comparative example.Its result, in embodiment 1 and 2, the matte of all square carpets does not all see stain, but in a comparative example, the matte of square carpet has seen stain.
But, use routine to knit after stain dyed yarn and replace light color to knit in the square carpet of embodiment 2 of after stain dyed yarn, pattern becomes slightly not distinct, and luminance difference is slightly weak compared with embodiment 1.
20 pieces of square carpets of embodiment 1,2 and comparative example are at random laid on the ground each via full slice system mode.
Find, in embodiment 1 and 2, in one piece of square carpet, to there is the position that luminance difference is large when looking around ground entirety, therefore, the luminance difference of seam portion is relatively inconspicuous, does not also have a part of square carpet noticeable, outward appearance as a whole as same monoblock carpet such.On the other hand, in a comparative example, easily can discover the seam portion between square carpet side by side, a part of square carpet is noticeable.
