Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warp knitted fabric whose surface is subjected to a raising treatment, and to a method for producing such a warp knitted fabric.
The present invention relates to a technique that can be applied to improve the quality.

[0002]

2. Description of the Related Art In order to facilitate understanding, a Russell lace place will be described as an example. The warp knitted lace fabric is formed by forming wales made of chain stitches with warp yarns and appropriately inserting weft yarns and patterned yarns between these wales (these yarns are referred to as insertion yarns). The lace fabric is highly evaluated when it has a volume in the thickness direction of the knitted fabric. From this point of view, river races are rated higher than Russell races. In the Russell lace, when the knitted fabric is viewed along the course, the inserted yarn is held down at each wale position by the warp yarns forming each wale,
Since it is difficult for unevenness to appear on the surface of the knitted fabric, it is difficult to obtain a thickness feeling. For this reason, in some cases, it has been attempted to provide a Russell machine with a drop plate so that part of the pattern yarn is removed from the chain stitch and floated on the surface.

[0003]

On the other hand, in the case of a knitted fabric, the surface of the knitted fabric may be raised, but this treatment is usually carried out by raising the entire surface at once. Complete. For example, in the case where the Russell lace fabric is subjected to a raising treatment, conventionally, only a uniform raising state is obtained over the entire surface, and there is room for improvement in the resulting unevenness of the knitted fabric. An object of the present invention is to obtain a method for obtaining a selected warp knitted fabric (for example, Russell lace fabric) in the sense of unevenness of the surface which is relatively highly evaluated.

[0004]

[Means for Solving the Problems] To achieve this object, a warp knitted fabric according to the present invention is knitted and formed, and then the surface of the obtained warp knitted fabric is raised, and the surface is raised. The characteristic means of the method for producing a warp knitted fabric for producing a knitted fabric is, as described in claim 1, for inserting warp knitting by inserting an insertion yarn, on the surface of a core yarn made of insoluble fiber. A knitted fabric including a first part having a partially soluble yarn wound with a soluble fiber as the insertion yarn and a second part having a non-soluble fiber as the insertion yarn to obtain a knitted fabric. Standing step, a raised treatment step of applying a raising treatment to the surface of the knitted fabric obtained in the knitting step, and a knitted fabric after the raised treatment obtained in the raised treatment step,
The step is to perform a dissolving and removing step of dissolving and removing the soluble fiber. In this method, the knitting process, the raising process, and the dissolving and removing process are sequentially executed. In this raising process, raising is performed on a required portion, which is an area including at least the first portion and the second portion, or the entire surface thereof. In this treatment step, when comparing the napped state of the first part and the second part, the soluble fiber is mainly napped in the first part and the non-dissolved part is in the second part. The surface of the natural fibers is raised. Therefore, when the dissolving and removing step is performed after such a raising process, the first part is not raised at all, or even if the raising process is performed, the degree of the raising process is not sufficient. The low core thread is exposed. On the other hand, in the second part, the thread that has been completely raised is exposed. Therefore, the degree of raising (raising amount) of the first portion is consequently weaker than that of the second portion.
As a result, it is possible to obtain a knitted fabric having on the surface thereof different portions in the degree of raising. This state is
The knitted fabric is given a feeling of unevenness.

Furthermore, after the warp knitted fabric according to the present invention for achieving the above object is knitted and formed, the surface of the obtained warp knitted fabric is raised to produce a warp knitted fabric whose surface is raised. A characteristic means of the method for producing a warp knitted fabric is, as described in claim 2, a soluble material layer formed on a surface of a core yarn made of insoluble fiber when inserting a warp knitting by inserting an insertion yarn. A knitting step of performing warp knitting to obtain a knitted fabric, comprising a first part having a partially soluble yarn as the insertion yarn and a second part having an insoluble fiber as the insertion yarn, A raising treatment step of subjecting the surface of the knitted fabric obtained in the knitting step to a raising treatment, and a dissolving removal for dissolving and removing the soluble fiber with respect to the knitted fabric after the raising treatment obtained in the raising treatment step. Execute the process. Even in this method, the knitting process, the raising process, and the dissolving and removing process are sequentially performed. In this raising process, the necessary portion including at least the first portion and the second portion or the entire surface thereof is raised. In this processing step,
Comparing the raised states of the first and second parts, the soluble material layer was mainly raised in the first part, and the surface of the insoluble fiber was raised in the second part. It becomes a state.
Therefore, when the dissolving and removing step is performed after such a raising process, the first part is not raised at all, or even if the raising process is performed, the degree of the raising process is not sufficient. The low core thread is exposed. On the other hand, in the second part, the thread that has been completely raised is exposed. Therefore, the degree of raising (raising amount) of the first part is
It becomes weaker than that of the department. As a result, it is possible to obtain a knitted fabric having on the surface thereof different portions in the degree of raising. This state gives the knitted fabric a feeling of unevenness in appearance.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. As described above, the present application includes a step of performing warp knitting and a step of subjecting the knitted fabric obtained by this operation to a raising process when manufacturing a lace fabric. The form of the final product will be described. In this embodiment, a case of using a Russell knitting machine will be described as an example. FIG. 1 is a structural diagram of a lace fabric having a ground structure excluding the pattern yarn, FIG. 2 shows a positional relationship of the wales 7 after knitting, and FIG. 3 has the ground structure shown in FIG. An organization chart of a lace fabric in which the pattern thread 5 is knitted in this ground organization is shown (however, in this figure, the wales 7 are shown by a chain line). As shown in FIG. 3, the lace fabric 1 of the present application is a pattern portion composed of a ground structure 4 formed by knitting a warp 2 and a weft 3, and a pattern yarn 5 knitted on the front side of the ground structure 4. It is composed of 6.
Further, as a macro, the pattern shown in FIG. 4 is obtained.

The details will be described below. First, as shown in FIG. 1, the ground structure part 4 forms a wale 7 by knitting a series of warp yarns (nylon yarn, which is an example of a chemical fiber yarn) 2 into a chain stitch, and at the same time, adjoining wales 7
The loops 8 are connected by wefts (also a nylon thread which is an example of a chemical fiber thread) 3 as appropriate to form a through hole 9 having a predetermined shape. Therefore, due to the insertion form of the handle yarn 5 and the through hole 9 formed between the wale 7 and the weft yarn 3, the lace material 1 exhibits a good lace pattern. Then, the handle portion 6 is formed in a manner to be woven into the ground structure 4. The state of the knitting structure of the pattern yarn 5 is shown in FIG. However, in the knitting work, these knitting works proceed at the same time. Here, the handle portion 6 is formed by knitting the handle yarn 5 so as to form a handle pattern, and the yarn 5 appears on the front side of the knitting lace 1 and, according to a predetermined design, for example, as shown in FIG. A pattern is formed on the surface of the knitted lace.

The outline of the race ground 1 is as described above.
The texture of the lace fabric 1 corresponds to the raising operation on the surface side after the knitting work, and therefore has a unique texture (net texture).
Has been adopted. FIG. 1 is an organization chart in a knitted state of a lace fabric 1, and FIG. 2 shows an arrangement state of weft yarns 3 and wales 7 after knitting. In FIG. 2, the broken line is the position of the wale 7 shown in the organization chart (the same applies to the relationship between FIGS. 6 and 7 and the relationship between FIGS. 8 and 9 shown below). Ground organization 4
The knitting structure of No. 1 will be described. In the lace fabric 1 of the present application, between the pair of wales 70 and 71 continuously arranged in the weft direction of the lace fabric 1 from the lower side (left side in FIG. 1) in the weft direction. The first weft yarn 30 to be knitted and the second weft yarn (right side in FIG. 1) 31 to be knitted from the good side.
Is provided with a weft-overlapped crossover portion 10 knitted over a common loop 80 existing in a pair of wales 70, 71 to be targeted. Then, these weft overlapping crossover portions 10 are, in the warp direction of the knitting lace (the vertical direction in FIG. 1 and the wale forming direction), the latitudinal direction upper side (left side in FIG. 1) with respect to the specific wale 70. And the lower side (right side in FIG. 1) are alternately arranged.
In the weft overlapping portion 10, the weft yarn 3 is double knitted so that the interval between the pair of wales 70 and 71 in which the weft yarn 3 is woven is narrowed, and as shown in FIG. It will move to an intermediate position between them. Therefore, in the weft portion other than the weft overlapping crossover portion 10,
The weft portion that extends between the wales 70 and 71 that are continuous in the weft direction is formed as an obliquely arranged weft portion 33 that is tilted from the warp direction and the weft direction, and this portion 33 eliminates the problem that has conventionally occurred during raising. can do.

The above is the characteristic of the ground texture, and when the lace ground 1 is formed from only the ground texture 4, it is preferable to adopt the above-described texture over the entire surface of the lace ground in the case of surface raising. , When the handle 6 is provided on the lace surface side,
The ground structure 4 on the back side of the handle 6 is sufficient as a normal structure. Therefore, in the structure having the handle portion 6 shown in FIG. 3, on the back surface of the portion where the handle yarns 5 are densely arranged, a single weft yarn 3 is usually woven between the loops 8. The above-mentioned ground portion structure is adopted in the portion formed as the transition portion 34 and in which the handle thread 5 is hardly disposed.

The above is the configuration of the race ground 1. The manufacturing process of such a race ground 1 will be described in advance. Race place 1
In the production of, the warp yarn 2, the weft yarn 3, and the handle yarn 5 are knitted in accordance with the above-mentioned structure constitution. Therefore, as described above, according to the knitting operation, the weft overlapping portion 10
In the warp direction of the knitting race 1, the specific wales 70 are alternately formed on the upper side and the lower side in the weft direction, and the wales 70 and 71 on both sides are moved to the central portion in this portion. Therefore, in the weft yarn portions other than the weft yarn overlapping crossover portion, the weft yarn portions extending between the wales continuous in the weft direction are inclined with respect to the warp direction and the weft direction (for example, about 30 to 60 degrees in the case shown in FIG. 1). It is formed as the weft portion 33. After performing the above operation, raising is performed, and a raising machine (not shown) that performs such raising treatment is used for the raising of the race fabric 1 to be raised.
The cloth cloth roller, the emery roller (not shown), etc., which are rotationally operated, are arranged side by side at the portion where the is arranged, and the surface side of the lace can be treated. Here, in this raising operation, raising treatment is performed by a roller (not shown) that rotates along the forming direction of the wales 7 that form the base tissue 4. In the present application, since the weft thread 3 is arranged in an oblique direction, it is possible to avoid buffering the thread 3 with the needles, protrusions (not shown), etc. provided for raising the rollers (not shown), It is possible to satisfactorily raise the hair without causing eye strain or yarn breakage.

The above description is of the structure of the lace fabric 1 having a ground structure (net) which is preferable when raising the hair and the procedure of the knitting operation thereof. The characteristic structure of the present application will be described below. As explained earlier, FIG.
Each chain stitch is omitted in the drawing by a one-dot chain line, and the pattern thread 5 is appropriately arranged on this ground structure. In this drawing, the first part 50 referred to in the present application is shown in the upper left part of the drawing.
(In a predetermined weak raised state), a second portion 55 (in a stronger raised state than the first portion) in the present application is formed in the lower right portion. Further, FIG. 4 is a macroscopic view of the race ground 1, and for the purpose of illustration, the first portion 50 and the second portion 55 described above are arbitrarily arranged on the surface of the race ground 1. There is. The basic structure of the race ground 1 targeted by the embodiment is as described above, and a method for obtaining the race ground 1 having such a structure will be described below with respect to a typical manufacturing method. [First Embodiment: Example of Using Covered Yarn] When the lace fabric 1 is obtained by this method, as shown in FIGS. 3 and 5, when the lace fabric 1 which is a warp knit fabric is knitted, the insertion yarn is inserted. When the warp knitting is performed by inserting (typically the pattern yarn 5), the partially soluble yarn (typically the covered yarn) in which the soluble fiber 52 is wound around the surface of the core yarn 51 made of the insoluble fiber. 54)
First, a knitting step is carried out in which the first part 50 having the insert yarn as the insertion yarn and the second part 55 having only the bare yarn 56 which is the insoluble fiber as the insertion yarn are provided and warp knitting is performed to obtain a knitted fabric. Here, the covered yarn 54 is a yarn formed by winding another yarn 52 around the core yarn 51 as shown in FIG. 5A, and the yarn 52 wound around the outer peripheral portion is soluble (for example, Water-soluble vinylon), and its core yarn 51 is non-soluble (for example, nylon filament yarn). Therefore, this yarn 54 can be dissolved and removed by dissolving the soluble fiber 52 wound around the outer periphery by treating it with water after knitting. In the present application, such solubility is not limited to the case where the solubility is obtained in water, and a fiber that is soluble in alkali, acid or the like may be wound around the outer circumference. That is, in addition to water-soluble vinylon, acetate or the like can be used depending on the selection of the solvent. Solubility in the present application
The distinction of non-solubility is a definition for the solvent used at the time of dissolution removal treatment, and those that dissolve in the solvent used in this step are called solubility and those that do not dissolve are called non-solubility. Further, as shown in FIG. 3, for the first portion 50 located at the upper left, knitting is performed using the above-described covered yarn 54 as a pattern yarn, and for the second portion 55 located at the lower right, Knitting is performed by using the bare yarn 56 such as a normal nylon thread or cotton thread as a pattern thread. When the pattern yarns 5 do not form a specific handle portion 6 (the lower left portion of FIG. 3 for the covered yarn 54, the upper right portion of FIG. 3 for the bare yarn 56), these yarns 54, Knitting is performed so that 56 is arranged in the direction from the end portion of the handle 6 along the knitted fabric along the wales 7 where the yarns 54, 56 exist. In this way, after knitting, the predetermined regions forming the first portion 50 and the second portion 55 according to the present application can be separately formed according to the design of the pattern.

After the above steps, a raising process for raising the surface of the knitted fabric obtained in the knitting process is performed. The raising process here is in accordance with a conventional technique, and for example, the entire surface of the knitted fabric shown in FIG. 4 is uniformly raised to a predetermined extent (amount). At this time, if the degree (amount) of raised hair is set so that only the soluble fibers 52 on the outer peripheral side of the covered yarn 54 are raised, the covered yarn 54 will be covered with the dissolved and removed treatment. The area provided with the yarn 54 is an area where hair raising is hardly performed. On the other hand, the area where the bare yarn 56 made of the insoluble fiber is used is brought into a considerably raised state by applying the raising treatment, so that the portion is subjected to a predetermined raising treatment. Differently from the above, if the degree (amount) of nap raising is set to such a degree that even the surfaces of the soluble fiber 52 and the core yarn 51 on the outer peripheral side of the covered yarn 54 are napped, dissolution and removal will be described later. When the treatment is performed, the portion provided with the covered yarn 54 has a weaker degree of raising the hair than the other portion. On the other hand, the area where the bare yarn 56 made of the insoluble fiber is used is brought into a considerably raised state by applying the raising treatment. Therefore, the portion where the predetermined raising treatment is stronger than the above-mentioned weak raising portion is performed. Can be formed. By the way, after passing through the raising process as described above, the soluble fiber 52 is dissolved and removed from the raised fabric obtained in the raising process (for example,
If water-soluble vinylon or the like is used, it is washed with water). By doing so, as shown in FIGS. 3 and 4, the first portion 50, which is not or is not napped, and the nap that is stronger than the first portion 50 (amount) is raised. The two parts 55 can be obtained on the same race ground 1.

[Second Embodiment: Example of Using Covered Yarn] In this example, instead of using the covered yarn 54 described above, the covered yarn 5 having a soluble material layer 57 on its surface is used.
Use 8. Except for this point, the first embodiment described above is followed. When the lace fabric 1 is obtained by this method, when the lace fabric 1 which is the warp knitted fabric is knitted, the insertion yarn (typically, the pattern yarn 5) is inserted to perform the warp knitting, and the warp knitted fabric is made of insoluble fiber. A partially soluble yarn having a soluble material layer 57 on the surface of the core yarn 51 (typically, a coated yarn 58 coated with a soluble resin as shown in FIG. 5B) is used as an insertion yarn. A knitting step is first performed in which a part 50 and a second part 55 having a bare yarn 56 of only insoluble fiber as an insertion yarn are provided and warp knitting is performed to obtain a knitted fabric. Here, the covering yarn 58 is
As shown in FIG. 5B, it is a yarn in which the core yarn 51 is coated with a soluble material, and the outer peripheral portion is a coating layer 57 (for example, a water-soluble vinylon layer) of the soluble material. Thread 51
Is insoluble (for example, nylon filament yarn). Therefore, the yarn 58 is treated with water after knitting, so that the soluble material layer 5 formed on the outer periphery is treated.
7 can be dissolved and removed. Such solubility is
In the present application, the present invention is not limited to the case where the solubility is obtained in water, and a fiber which is soluble in an alkali, an acid or the like may be wound around the outer circumference. Also in this case, according to FIG. 3, the first portion 50 located at the upper left is knitted using the above-described covering yarn 58 as a handle yarn, and the second portion 55 located at the lower right is provided. The knitting is performed by using the bayard yarn 56 such as a normal nylon thread or cotton thread as a pattern thread. The respective handle yarns 5 are located at a portion where the specific handle portion 6 is not formed (the lower left portion of FIG. 3 in the case of the covering yarn 58 and the upper right portion of FIG. 3 in the case of the bare yarn 56). 56
The knitting is performed so that the yarns 58 and 56 are arranged in the direction from the end portion of the handle along the existing wales 7 through the knitted fabric. By doing this, similarly to the first embodiment described above, after knitting, the predetermined regions forming the first portion 50 and the second portion 55 according to the present application are respectively formed according to the pattern design. be able to.

After the above steps, as in the previous example,
A raising process is performed to apply a raising process to the surface of the knitted fabric obtained in the knitting process. The raising process here is in accordance with the conventional technique, and for example, the entire surface of the knitted fabric is uniformly raised by a predetermined amount (amount). At this time, if the degree (amount) of nap raising is such that only the soluble material layer 57 on the outer peripheral side of the covering yarn 58 is raised.
When the dissolving and removing treatment described later is performed, the covering yarn 58
The part provided with is a part where hair raising is hardly performed. On the other hand, the area where the bare yarn 56 made of the insoluble fiber is used is brought into a considerably raised state by applying the raising treatment, so that the portion is subjected to a predetermined raising treatment.
Differently from the above, the degree (amount) of nap is determined by the covering yarn 58.
The outer peripheral side of the soluble material layer 57 and the core yarn 51.
When the surface is also raised to the extent that it is raised, the portion provided with the covering yarn 58 is a portion where the degree of raising is weaker than that of another portion when the dissolving and removing treatment described later is performed. On the other hand, the part using the bare yarn 54 made of insoluble fiber is in a considerably raised state by performing the raising process. Therefore, the part subjected to the predetermined raising process which is stronger than the above-mentioned part where the raising degree is weak is applied to the part. Can be formed. Now,
After passing through the raising process as described above, the soluble material layer 57 is dissolved and removed from the raised fabric obtained in the raising process (for example, when a water-soluble vinylon or the like is used). Performs a washing process). By doing so, the first part 50 that has not been napped or has a weak degree and the second part 55 that has a higher degree (amount) of nap raising than the first part are placed in the same race place. Obtainable.

[Third Embodiment: Example of Using Covered Yarn] In contrast to the first and second embodiments described above, which involve dissolution and removal treatment, this embodiment Then, as the thread used as the insertion thread (mainly the handle thread 5),
It is characterized by having different twists depending on the part to be used. Therefore, in this embodiment, it is not necessary to perform the dissolving and removing process described so far. That is, in this embodiment, after the lace fabric 1 is knitted and formed, the surface of the obtained warp knitted fabric is napped to produce a warp knitted fabric whose surface is napped. Thread 5
A first part 50 in which the first twisted yarn 61, which has been twisted to a predetermined degree, is used as the inserted yarn when the warp knitting is performed by inserting
A second twisted yarn 62 that is weaker in twist than the first twisted yarn 61.
And a second portion 55 which is an insertion yarn, warp knitting is performed to obtain a knitted fabric (knitting step). To explain using FIG. 3 described above, for the first portion 50 located at the upper left, a relatively strong twist of a predetermined degree (for example, 1000 t / inc.
The first twisted yarn 61 subjected to h) is knitted as the pattern yarn 5 and weaker than the first twisted yarn 61 with respect to the second portion 55 located at the lower right (for example, a relatively weak twist amount is 600).
(t / inch) Knitting is performed using the second twisted yarn 62 as the pattern yarn 5. Each pattern yarn 5 is located at a position where the specific pattern portion 6 is not formed (lower left portion of FIG. 2 in the case of the first twisted yarn 61, upper right portion of FIG. 2 in the case of the second twisted yarn 62). Thread 6
Knitting is performed so that the yarns 1 and 62 are arranged in the direction from the end portion of the handle 6 along the knitted fabric along the wales 7 where the yarn exists.

Then, after the above steps, a raising treatment step of applying a raising treatment to the surface of the knitted fabric obtained in the knitting step is executed. The raising process here is in accordance with the conventional technique, and for example, the entire surface of the knitted fabric is uniformly raised by a predetermined amount (amount). At this time, the degree (amount) of brushing
If the first twisted yarn 61 is set so that it is hardly raised, the portion provided with the first twisted yarn 61 is a portion where almost no raising is performed. On the other hand, the portion where the second twisted yarn 62 is used is a portion that has been subjected to a predetermined raising treatment, because a considerable raising state is obtained by performing the raising treatment.
Differently from the above, the degree (amount) of raising is determined by the first twisted yarn 6
With respect to 1, if the outer circumference is raised,
The portion provided with the first twisted yarn 61 has a degree of raised hair weaker than other portions. On the other hand, since the portion using the second twisted yarn 62 is brought into a considerably raised state by performing the raising treatment, it is possible to form a portion subjected to a predetermined raising treatment which is stronger than the above-mentioned weak raising portion. it can. As described above, the first portion 50 that has not been napped or is weak, and the degree (amount) of nap raised from the first portion 50.
The strong second part 55 can be obtained on the same race ground.

[Other Embodiment] 1. In the embodiment shown in FIG. 1 and FIG. 2, the case where the weft overlapping crossover portion is formed between three continuous loops on one side between the pair of wales is shown, but this number can be any number of 2 or more. You can choose to. In the example shown in FIGS. 6 and 7, this is formed between two continuous loops on one side. 2. Further, in the example shown in FIGS. 1 and 6, the weft overlapping crossover portions are formed with the same length between the pair of wales (between four courses) on the left and right respectively, but different lengths are provided as shown in FIGS. You may form in. However, it is necessary that the entire fabric has symmetry in consideration of the skew of the knitting. 3. Further, as shown in FIG. 3, in relation to the portion to be fluffed, the normal single weft yarn extends between the wales in the portion of the ground tissue that is less in contact with the raising cloth roller or the emery roller. It goes without saying that it can be arranged as a unit. 4. In the above embodiment, the knitting lace having the pattern yarn 5 on the surface side has been mainly described, but this may be a lace ground having only the ground structure. That is, in this case, the weft plays a role as an insertion yarn, and as the insertion yarn, those having different melting characteristics may be used. In addition, a stretchable lace fabric with knitted rubber threads (spantex) along the wale formation direction, and also with a pile yarn knitted on the back side of the lace fabric along the wale formation direction. The present application can be applied to ones. When it has stretchability, it is possible to widen the width of the product, and when the front side is raised by the method of the present application and the pile yarn made of cotton fiber or the like is arranged on the back side, it is soft to the touch and further to the fabric. It is possible to provide a knitted lace that is very soft. Furthermore, in the case of raising the pile yarn on the back side, it is possible to obtain a double-sided raised product in a lace fabric, which has been considered to be impossible to produce at all without causing problems such as eye slippage and yarn breakage. 5. The type of race place is not limited to the Russell race, but may be a river race, for example. 6. As the brushing means, as described above, a clothing cloth roller, or a Franz Muller brushing machine equipped with an emery roller,
Alternatively, it is general to use a beaver emery raising machine equipped with an emery roller, but in the case of the present application, since the weft yarn of the lace fabric is obliquely arranged, the degree of buffering with this yarn is low, and any raising A machine can be used to raise the hair satisfactorily. 7. Further, in the above-mentioned embodiment, the nylon thread which is the chemical fiber thread is adopted as the warp thread and the weft thread, but instead of this, polyester thread, silk thread, cotton thread or the like may be adopted. Further, as the thread that easily naps, spun thread of natural fiber or chemical fiber, multifilament thread, and high multi thread having more filaments than this multifilament thread can be used. On the other hand, in the above-described embodiment, the raising of the entire knitted fabric is shown. However, in the present application, if the first part and the second part are raised under the same condition, the object of the present application can be achieved. it can. In addition, the degree of raising can be adjusted by adjusting the amount of the soluble fiber or the layer thickness of the soluble material layer.
Both the first part and the second part are made of yarns coated with soluble fibers or provided with a soluble material layer, and the coating amount, layer thickness, etc. are changed between the two parts, and the first and second parts are used. You may change the raised state with.
