shrinkage filament yarns in a pattern. How to make a patterned pile knit fabric.
2, the scope of claims
3. Detailed Description of the Invention The present invention is a yarn in which filament yarns
having different submersion shrinkage rates are simultaneously subjected to fluid entanglement
processing and entangled with each other, and entangled portions and non-entangled portions
are intermittently formed in the length direction. The present invention relates to a method for
producing a patterned pile fabric in which a contact pattern is formed on a hairy fabric using a
strip as a pile of a pile fabric. 0 Conventionally, a filament yarn using a pile yarn as opposed to a
base yarn It is known that tricot 7 lenti piles having a length 1.5 to 3 times more woven, or
sinker piles having a round knitting, etc. are known. It is also known to use a mechanical
patterning mechanism to show patterns by long and short piles. However, these methods do not
cause any problems in the case of pile fabrics using spun yarn, but in the case of filament yarn
use, if the pile length is uneven or the pile is too long # 1 There is a drawback that it can not
produce good-quality products because it causes fluffing during snowing and squeezing,
catching, and entanglement during dyeing. In addition, with a mechanical patterning machine,
the patterned part is a short pile with a short pile, and the other part is a two-tiered pile knitting
in which the pattern is expressed by a long pile, or A sinker pile knitting machine with a card has
been proposed. However, these methods not only require labor, but in the case of a filament yarn

knit fabric, a focused portion, an opened portion, or uneven pile length 9 wear There is a
drawback that the high quality product can not be obtained by causing snagging 1 fluff inside,
scratching EndPage: 1 during dyeing processing, catching, entanglement and the like. Reminder
and feel to eliminate the above-mentioned drawbacks with filament yarn use. In order to improve
the appearance, it is known to use a bulky yarn such as a temporary Karoye yarn, or a mixed
yarn having a difference in yarn length, an interlacing yarn, etc. However, a pattern is common to
knitting machines having a pattern. The boundaries between parts and other parts do not appear
clearly. At the same time, using a dedicated pattern knitting machine has the disadvantage of
being expensive. The present invention solves the defects such as the snagging of the filament
yarn using / e-il knitted fabric, and produces a high quality patterned pile fabric by a simple
operation by using the filament yarn to produce a snag <<< The purpose is to provide According
to the invention of this application, a high shrinkage filament yarn and a low shrinkage filament
yarn which are different from each other and have different submersion shrinkage rates by 10 or
more are fluidly entangled with each other from K, and the entanglement portion and the nonentanglement portion are not Production of a patterned pile fabric characterized by using a yarn
formed intermittently with a entangled portion as a pile yarn to knit a circular knit fabric and
then heat treating the low shrinkage filament yarn in a pattern. It is a method.
As a high shrinkage filament in this invention. Multifilament yarns of thermoplastic synthetic
fibers such as polyamides, polyesters and polyacrylonitriles are preferable, and multifilament
yarns of regenerated cellulose fibers are preferable as the low shrinkage fibers. The length of the
non-entangled portion of the pile yarn is preferably in the range of 15 to 60 °, and if the length
of the non-entangled portion is 15 or less, the height of the pile is not equal to that of the long
and short two layers. In addition, if the length of the non-entangled portion exceeds 60%,
filament breakage, thread breakage, etc. occur during knitting, which is undesirable in 0 fluid
injection processing, the multifilament thread length with a small heat shrinkage rate is the heat
shrinkage rate Feed and merge both yarns with an overfeed equal to or less than 10- to the
length of the large thermoplastic synthetic fiber filament yarn, and jet the high-speed fluid flow
from the combined yarn vertically from the t1 direction, Without turning. By providing a single
fiber or single fiber group interlacing while keeping the fiber in a flat state, as shown in FIG. 1,
the non-interlacing part t1 and the interlacing part t2 can be formed intermittently. . Before heat
treatment, this yarn is in the form of a converged system as a whole, and there is almost no
torque. In this case, when one of the supply yarns is subjected to a vertical fluid flow
intermittently using a filament yarn processed from a larger temporary yarn, the entangled
portion may be cut even if the overfeed rate is 10% or less. And the entangled pitch of the nonentangled portion t1 becomes 14− or less on average. Temporarily, the processed yarn
constitutes the periphery of the yarn bundle, that is, the sheath portion, and the non-crimped
filament yarn constitutes the central portion, which makes it easy to generate torque. For this
reason, in the present invention, the yarn to be entangled is a non-knitted non-barbed filament
yarn for both yarns. FIG. 2 shows a stitch configuration diagram in which the intertwined yarn of

the present invention is applied to a pile yarn of a sinker pile knit with a texture. In the figure,
thermoplastic synthetic fiber filament yarn 2 having a large diving shrinkage rate and a filament
yarn having a diving shrinkage rate smaller than that by 10 or more, for example, cellulose
regenerated fiber filament yarn 1 has a texture in the silk fabric. Not only in the needle loop of
the other provisionally machined yarn 5 that constitutes the yarn but also in the sinker loop.
Since the single fibers or single fibers of the entangled portion are mutually entangled, pile
stitches are formed in a connected state. The ground yarn is optimally a textured yarn, and a
yarn having a residual shrinkage ratio as large as possible is preferable. さらに。
It is desirable that the denier ratio to pile yarns be as close as possible. If heat treatment is
carried out appropriately after such intermingled yarn formation. As shown in FIG. 2 to FIG. 3,
each yarn shrinks and the whole stitch becomes smaller, but in the pile stitch consisting of
entangled yarn at 45 F, the high shrinkage component shrinks remarkably and the high
shrinkage filament yarn The difference in contraction between 2 and the low shrinkage filament
yarn 1 dusts the pile formation state in which both are clearly divided into two layers in one
stitch. This is a configuration that can not be formed at all by other mixed yarns or synthetic
yarns. EndPage: 2 FIG. 4 is a cross-sectional view of the silk fabric of FIG. 3 as viewed from
above. It can be seen that, as the water shrinkage rate of the thermoplastic synthetic fiber
filament yarn 2 is larger, the difference in yarn length with the low shrinkage filament yarn 1
becomes remarkable. Furthermore, the intertwined yarn of the present invention has an average
length of 15 or more non-entangled portions, and has a pile length of 1.0 to 55 m or a pile tricot
knitted fabric or trichocto raised in a normal sinker pile fabric. Even in consideration of runners
150 to 340'M <ack, which is the knitting length of the knitted fabric, the non-entangled portion
is held over several times or several times the pile length. In the ninth aspect, single BI yarn
feeding of multifilament yarn, or knitting yarn feeding can be carried out by the same technique
without any change with uniform yarn feeding, but rather the intertwined yarn of the present
invention is more stable It can be woven in a state of stretching. Moreover, the pile napping
effect in the knitted fabric does not change at all. In particular, the intertwined yarn of the
present invention comprises a thermoplastic synthetic fiber multifilament yarn having high
shrinkage. Since the contraction of the whole intertwined yarn has a shot with the heat treatment
but the difference of the yarn length of 1 m each component has a gap of 20% or more, the
thermoplastic synthetic fiber multifilament yarn 2 never comes to the surface of the pile fabric I
will not show my face. Since the surface is covered with only one regenerated R # IIL
multifilament yarn 1, the same knitted fabric appearance as in the case of single knitting is
exhibited. By this, for example, when the yarn length difference is about 35 t and 1irt L, and the
pile sinker height 2.7 of the sinker pile knitting machine is attached and knitted, and heat
treatment is performed, the pile high consisting of entangled yarns I'i, one of the thermoplastic
synthetic fiber martefilamen) J can obtain a short pile of about 1.9 m, at a height of about 5 mm
due to some shrinkage of the regenerated horizontal fine multifilament yarn . Furthermore, if it is
an intertwined yarn having a combination of yarn length differences exceeding 6 ohms, the
18-04-2019

height of the short pile is about 1.5 極 め て, a very low pile length and p, manufactured by a
dedicated two-step pile knitting machine You can get a pile fabric that is almost the same.
FIG. 5 shows a stitch configuration diagram in a state of being subjected to a hot water removal
treatment applied to a satin tricot structure, and the intertwined yarn constituting the front yarn
can be seen in the shincal pile fabric of FIG. The thermoplastic synthetic fiber multifilament yarn
2 and the cellulose yarn regenerated fiber multifilament yarn 1 appear as a difference in yarn
length, just like the above phenomenon. Although the Cellulosian regenerated fiber filament yarn
1 is drawn to be slack in four times, the two components of the interlacing yarn are merely
drawn to avoid overlapping in terms of expression in the fluctuating width, and the concept is
What is shown for the best understanding is the vertical cross-sectional view of FIG. In the same
figure, it can be seen that 1 and 2 of the entangled yarn acid have a significant difference in pile
height. Thus, for example, when an intertwined yarn having a yarn length difference of more
than 40 inches is used as a front yarn of a two-sheet twill satin-tricot structure, a range of 24 to
28 gauge and 50 to 80 courses of knitting At / 2.541 yn. The ground yarn is 40 to 75 denier of
ordinary polyamide or polyester filament yarn and has a contraction rate of 6 to 7 in seawater,
and the pile height of regenerated multifilament yarn of pile tricot fabric after hot water
treatment is about 2 to 3 m On the other hand, that of one thermoplastic synthetic fiber
multifilament yarn has shrunk to a length of almost 6 wales, and there is only a slight pile
simplicity, and if the brushing is further advanced, the pile is brushed and the length is about 2
■ You get raised hair. Furthermore, when the swing width of the front was expanded to 5 to 8
hands by using 3 sheets of OSA 2. It was possible to obtain a large napping with a length of 8 to
10 as long as the n + cut length of the P + raw fiber multifilament yarn. Thermoplastic synthetic
fiber multifilament yarns for imparting the potential product shrinkage and yarn length
difference possessed by the entangled yarn of the present invention are all compositions such as
polyamides, polyesters and polyacrylonitriles. As long as the number of filaments is six or more.
As the polyamide system, for example, poly (.epsilon.-caproamide) or polyhexamethylene
adipamide which is obtained by copolymerization of various amide forming compounds is used.
In addition to this, hexamethylenediammonium phthalate is copolymerized and fc is also used as
EndPage: 3. The polyester type is, for example, one obtained by using terephthalic acid as a main
dibasic acid, and using glycol as ethylene glycol or cyclohexane dimetatool as a main glycol, or
using ethylene oxybenzoate as various glycols. It may be copolymerized with an ester-forming
compound.
In addition to this, a copolymer of isophthalic acid or methoxypolyethylene glycol as a third
component is also used. ここで。 The addition amount of the third component is 2-0 to Fk, and if
it is 5 moles, a high shrinkage yarn having a water shrinkage ratio of 20- or more can be
obtained. On the other hand, as cellulose-based regenerated fibers, those spun from the viscose
method or the copper ammonia method are used. These can control the boiling-water shrinkage

rate depending on not only the stock solution but also the production conditions, and are as low
as about 3- and as high as about 7-8-. In one or more of the above descriptions, the yarn length
difference after diving shrinkage is, for example, the sample length of the interlacing yarn, about
25 aar (with a load of 0.1 f per denier), and 2 to 2 from both ends of the sample. After marking
each 51, separate the two yarns carefully and for each yarn bundle measure the length between
the aforementioned parts under a load of 0.1 f per denier. Is calculated five times, and the
average value is taken. In addition, the average of the non-parent interlacing pinch is the average
length of the portion indicated by the length tl in FIG. 1, and a pin is pierced with a thread under
a load of 1 f / d. Add another 2f load to the pin. The distance that the pin can move along the
yarn axis is measured at five points per tangled yarn, and this is performed ten times to take an
average. As a pile contact means. When regenerated fibers are used for low-shrink yarns, only
the regenerated fiber filament yarn is chemically dissolved and carbonized, and the other
thermoplastic synthetic fiber filament yarn is damaged or embrittled, etc. It is necessary to apply
drug treatment without any influence. Here, chemicals used for chemical treatment include
sulfuric acid, hydrochloric acid, aluminum chloride, magnesium chloride, and aluminum sulfate /
minirum, which are wet as carbonization methods. There is a dry method, the latter case is
relatively easy 0 In this case, the application of chemical treatment to the pile fabric. After
knitting, it is desirable to go through relaxation scouring, and heat treatment and carbonization
need to be separate steps to avoid that the effect is halved if fibers with large thermal contraction
are treated in the carbonization step. Furthermore, when used in combination with shearing, in
particular incorporating it in the pre-shearing step improves the patterning effect. As a further
point to be noted, after chemical treatment, the carbonized debris is washed away with sufficient
water and then left in the fiber Perform alkaline soaping to neutralize the acid. As alkali, it is
common to use soda ash which does not relatively affect the coloration.
After being completely post-treated as such, it is supplied to the dyeing process. Example
filament I: polyamide 70D-36F having a boiling water shrinkage of 30%. Filament ■: boiling
water shrinkage & 4-viscose rayon yarn (75D-54F). この1. Both filament yarns of I [were
supplied and merged so that the latter had a long yarn length of 5 憾, and intermittent
confounding was performed under an air pressure of 1.2 to (gauge pressure). The intermittent
entangled yarn is used as a front yarn with a 24 gage, tricot knitting machine (Karlmayer 'JJ:
KE5) and a satin tricore with a narrow width by using the obtained intermittent entangled yarn
as a front yarn and a runner 304 Qll /. 1. Runner 156c'5 / R, to middle yarn and back yarn,
polyamide 70D-36F with seawater shrinkage of 6%. After knitting under the conditions of 19
knitting courses 50 / z 54ctm and dyeing processing of polyamide and rayon with different
shades of light and shade (step dyeing), the long product in which rayon fibers are in contact
with the pattern is good coloration of rayon. In addition to the color development of the
polyamide, EndPage: 4 properties were added, and a light and dark difference was mixed and
mixed to obtain a product having an irregular effect and having a different color pattern.
