Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a knitted lace with a patterned pattern having raised portions.
[0002]
[Prior art]
The knitted lace is formed by warp yarns, has a wale extending in the first direction, and a plurality of wales arranged in a direction orthogonal to the first direction are connected by weft yarns to knit the knitted fabric. The knitted fabric has predetermined through holes by warps and wefts. By selecting the position where the weft is knitted into the wale, the shape and arrangement of the through holes are adjusted, and a lace pattern is formed on the knitted fabric. The knitted fabric is formed with a dense pattern portion into which the pattern yarn is knitted and a sparse base portion into which the pattern yarn is not knitted. It is formed. Such a patterned knitted lace is widely used, for example, for women's underwear.
[0003]
When the base part with a loose knitted fabric is used in a place where the garment directly touches the skin, there is a problem that the touch and sweat absorption are poor. For this reason, in the conventional technology, a net-like bonding material knitted with cotton yarn, etc., which is excellent in touch and sweat absorption, is separately bonded to the part of the knitted lace that directly touches the skin to improve the touch and sweat absorption. ing. However, the use of the bonding material causes a problem that the manufacturing process becomes complicated and the manufacturing cost increases, and the bonding material can be seen through the through holes, so that the aesthetic appearance of the pattern is impaired.
[0004]
In order to solve such a problem, other conventional knitted laces that improve the touch without using a bonding material are well known.2These are sectional views showing a conventional knitted lace 70. The knitted lace 70 includes a floating yarn 73 having a protruding portion 53a that partially protrudes in one thickness direction. The floating yarn 73 is subjected to raising treatment after knitting of the knitted fabric, whereby fuzz 53b is formed in the protruding portion 53a. With the fuzz 53b, the knitted lace 70 is configured to obtain a raised state, to improve the touch, and to obtain sweat absorption.
[0005]
FIG.3These are sectional drawings which show simplified the raising apparatus 60 for performing the raising process of the knitted lace 70. FIG. The raising device 60 includes a plurality of raising rollers 62, a rotating drum 63, a supply roller 61, and a discharge roller 64. The rotating drum 63 rotatably supports a plurality of raised rollers 62 arranged at equal intervals in the circumferential direction. The supply roller 61 supplies the knitted fabric 51 toward the rotary drum 63, and the discharge roller 64 discharges the knitted fabric 51 discharged from the rotary drum 63 from the rotary drum 63 toward the next process. Each raised roller 62 is wound with a cloth, emery paper, or the like on the outer periphery of the roller for forming fluff on the knitted fabric 51.
[0006]
The knitted fabric 51 is conveyed by the supply roller 61 along the outer peripheral surface of the rotary drum 63. In the knitted fabric 51 conveyed to the position facing the outer peripheral surface of the rotating drum 63, the protruding portion 53 a of the floating yarn 73 contacts the raised roller 62. The raising roller 62 partially cuts the fibers of the protruding portion 53a to form the fluff 53b in the protruding portion 53a. After the fluff 53b is formed on the protruding portion 53a, the knitted fabric 51 is discharged from the rotary drum 63 by the discharge roller 64. By performing this operation, a wing 53b is formed on one side 52 in the thickness direction, and the knitted lace 70 is in a raised state. The floating yarn 73 for forming the fluff 53b is selected to have a thickness that prevents the yarn itself from being cut during the raising process. Such a knitted lace 70 and a manufacturing method thereof are disclosed in Japanese Patent No. 2357783.
[0007]
FIG.4These are knitting | organization organization charts which show the conventional knitting lace 70. FIG. In the knitted lace 70, the knitted fabric 51 is knitted by the warp 71, the weft 72, and the floating yarn 73. The knitted fabric 51 has a chain stitch structure, and a plurality of wales 74 are formed by the warp 71. Each of the wales 74 extends in the first direction A, which is the direction in which the wales 74 extend, and is arranged in a second direction B orthogonal to the first direction A.
[0008]
The floating yarn 73 has a knitted portion 73a that is knitted into the loop-shaped portion of the wale 74 and a free portion 73b that is released without being knitted into the loop-shaped portion. In the floating yarn 73, when the knitted portions 73a arranged in the first direction A come close to each other, the free portion 73b protrudes in one thickness direction of the knitted lace, and each free portion 73b comes close to the first direction A, It is densely arranged in one direction A.
[0009]
The free portion 73 b becomes a protruding portion 53 a that protrudes convexly toward the one side 52 in the thickness direction of the knitted lace 70. By raising the protruding portion 53a by the raising device 60 described above, the knitted lace 70 obtains a raised state.
[0010]
Further, when a pattern is formed on the knitted lace 70, the pattern yarn is knitted into the wale 74 and the pattern portion is not knitted into the wale 74 and is transparent. And a sparse base portion having a hole and a small area of yarn per unit area. The pattern portion and the base portion are combined to form a knitted fabric 51 with a pattern pattern.
[0011]
[Problems to be solved by the invention]
FIG.2And FIG.4In the conventional knitted lace 70 shown in FIG. 2, the floating yarns 73 are partially curved and close to the first direction A and are densely arranged in the first direction A. The floating yarn 73 has a thickness that prevents the yarn itself from being cut during the raising process, and a thicker yarn is selected as compared with other yarns. When the floating yarn 73 is knitted into the wale 74, the knitted fabric 51 has a large volume of yarn per first direction A.
[0012]
The pattern portion having a clear contrast is formed in the ground portion and the pattern portion as the density difference of the yarn is larger, that is, as the difference in the area of the yarn per unit area is larger. However, when the floating yarn 73 is knitted in order to improve the touch, the yarn area per unit area is increased in the base portion by knitting the floating yarn 73, and the yarn with the handle portion becomes larger. The density difference is reduced.
[0013]
Therefore, the knitted lace 70 has a problem that the density difference of the yarn between the base part and the pattern part becomes small, the contrast of the pattern does not become clear, and a clear pattern cannot be formed. Further, in order to form the fluff 53b, it is necessary to increase the protruding amount of the protruding portion 53a protruding to the one side 52 in the thickness direction, the protruding portion 53a having a large protruding amount closes the through hole, and the knitted fabric 51 is desired. There is a risk that it will not be formed into a lace pattern.
[0014]
Further, in the raising process, the floating yarn 73 is pulled to divide or cut the fiber to form the fluff 53b, and the warp yarn 71 and the weft yarn 72 other than the floating yarn 73 may be scratched or cut. As a result, the warp yarn 71 and the weft yarn 72 may be broken, and the knitted fabric 51 may fray and the quality of the knitted lace 70 may deteriorate. In this way, when the floating yarn 73 is knitted to form the fluff 53b, there is a problem that the possibility that the knitted fabric 51 is frayed increases. Moreover, the fiber isolate | separated from the knitted fabric by brushing may fly.
[0015]
Accordingly, an object of the present invention is to provide a knitted lace with a patterned pattern which is comfortable to touch and has a clear patterned pattern, without using a floating yarn for forming raised hair.
[0016]
[Means for Solving the Problems]
In the present invention, a plurality of wales in which a plurality of loop-shaped portions are connected in parallel are formed by warp yarns, and wales adjacent to each other in a second direction orthogonal to the first direction in which the wale extends are mutually connected by warp yarns or weft yarns. It is a knitted lace with a patterned pattern,
A base portion including a sparse portion in which insertion yarns are knitted into a plurality of loop-shaped portions adjacent to each other in a first direction of a predetermined wale;
The insertion yarn is knitted into a plurality of loop-shaped portions adjacent in the first direction of the predetermined wale, and includes a dense portion in which the pattern yarn is knitted into the loop-shaped portion adjacent to the second direction of the predetermined wale. Having a handle,
The base portion is a first base portion in which insertion yarns are knitted into a plurality of loop-shaped portions adjacent to each other in a first direction of a predetermined wale;
A second base portion in which stretchable yarns are knitted into a plurality of loop-shaped portions adjacent to each other in a first direction of a predetermined wale;
As for the said pattern part, while inserting yarn is knitted into the several loop-shaped part adjacent to the 1st direction of a predetermined wale, the patterned thread is knitted into the several loop-shaped part adjacent to the 2nd direction of a predetermined wale. The first pattern part,
A second handle portion in which stretch yarns are knitted into a plurality of loop-shaped portions adjacent to each other in a first direction of the predetermined wale and a pattern yarn is knitted into a loop-shaped portion adjacent to the second direction of the predetermined wale; Including
The insertion yarn includes a stretchable core yarn and a covering yarn wound around the core yarn, and this insertion yarn is in a natural state so as to be partially exposed facing one side in the thickness direction of the knitted lace. And is knitted into a loop part of a given wale,
Stretch yarn has a different elasticity from the insertion yarn and is stretched from the natural state and knitted into a loop portion of a predetermined wale.It is.
[0017]
According to the present invention, having a dense pattern portion and a sparse base portion, and combining the pattern portion and the base portion, the knitted fabric can be contrasted by the density difference of the yarn, A knitted lace can be formed. Further, when the insertion yarn is knitted in an extended state during knitting, the core yarn shrinks after knitting, and the covering yarn is separated from the core yarn and wound in a loose state with respect to the core yarn.
[0018]
Since the insertion yarn faces the one side in the thickness direction of the knitting lace and is partially exposed, the loose portion of the covering yarn in the portion where the insertion yarn is exposed protrudes to one side in the thickness direction of the knitting lace. This loose part becomes fuzz which protrudes to the one side in the thickness direction so as to be deformable, in other words, an annular raising, and the knitted lace can obtain a raised state. Thereby, the touch when touching the knitted lace can be improved. Further, since the insertion yarn is also knitted in the base portion, the raised portion can be formed also in the base portion, and the touch can be improved satisfactorily on the entire surface on one side in the thickness direction of the knitted lace.
[0019]
Further, since the insertion yarn contracts with respect to the first direction, it does not bend to one side in the thickness direction of the knitted lace unlike the floating yarn of the prior art and does not become dense in the first direction. As a result, even if the insertion yarn is knitted in the base portion, the area of the yarn per unit area of the base portion can be reduced. Therefore, it is possible to increase the density difference between the yarns of the pattern part and the base part, to clarify the contrast of the pattern, and to form a clear pattern.
[0020]
Therefore, it is possible to have a well-defined and clear pattern without providing floating yarns for forming raised hair.
Further, according to the present invention, the second base portion and the second handle portion are knitted with stretch yarns having different stretch amounts with respect to the insertion yarn. The amount of expansion / contraction of the insertion yarn is limited by the covering yarn, whereas the expansion / contraction yarn has a wide range of expansion amount in which the expansion / contraction yarn can be knitted, and the expansion / contraction amount can be easily changed. Thus, by changing the stretch amount of the stretchable yarn knitted into the knitted lace, it is possible to easily form the knitted lace having different stretchability regardless of the stretch of the insertion yarn.
[0021]
In the present invention, the stretchable yarn is stretched by a stretch amount larger than the stretch amount of the insertion yarn that is stretched and knitted from a natural state, and is knitted into a loop portion of a predetermined wale.
[0022]
According to the present invention, stretchable yarns are knitted in the second base portion and the second handle portion. The stretchable yarn is knitted by being stretched with an extension amount larger than the extension amount of the insertion yarn being stretched and knitted.
[0023]
In the natural state, the tension is released on the yarn. The extension amount is, for example, the length of the yarn portion that is extended by extending the yarn portion per unit length in the natural state of the yarn.
[0024]
The insertion yarn and the stretchable yarn knitted in the stretched state shrink after the knitting, and the knitted lace shrinks by the insert yarn and further shrinks by the stretchable yarn.
[0025]
Specifically, each loop-shaped part in which stretchable yarns are knitted are close to each other in the first direction, and the wale shrinks in the first direction. Moreover, since each wale is mutually connected to the wales adjacent in the second direction, the other wales adjacent to the second direction of the wales to be shrunk also shrink in the first direction. As the wale shrinks in this manner, the knitted lace contracts.
[0026]
When the insertion yarn is knitted into the wale that is shrunk by the stretch yarn, the insertion yarn further shrinks than the insertion yarn itself shrinks in the first direction after knitting. As a result, the core yarn constituting the insertion yarn further shrinks, and the interval between the coated yarn and the core yarn is increased.
[0027]
As a result, the protruding amount of the covering yarn protruding toward the one side in the thickness direction of the knitted lace increases, and the length of the fluff protruding toward the one side in the thickness direction of the knitted lace, and therefore the length of the ring raising is increased. As a result, the knitted lace can obtain a larger raised state, and the touch when the knitted lace is touched can be further improved. In addition, by knitting stretch yarns, a stretch knitted lace can be realized more reliably and a fit can be obtained.
[0028]
Even if the extension limit of the covering yarn is small and the tension when the insertion yarn is knitted in the stretched state cannot be increased, the stretch yarn different from the insertion yarn is knitted in the large stretched state, The insertion yarn can be sufficiently contracted after knitting, a gap between the covering yarn and the core yarn can be provided larger, and a sufficient ring raising can be obtained.
[0029]
Further, the invention is characterized in that the coated yarn has a hygroscopic property.
According to the present invention, the knitted lace can form fluff having hygroscopicity on one side in the thickness direction, and can obtain hygroscopicity on one side portion in the thickness direction of the knitted lace. For example, by providing one side in the thickness direction of the knitted lace in a portion that contacts the skin, sweat can be absorbed to prevent stuffiness.
[0030]
In the present invention, the thickness of the insertion thread is 0.5 times or more the thickness of the warp thread, and
It is characterized by being 25 times or less.
[0031]
According to the present invention, when the thickness of the insertion yarn exceeds 25 times the thickness of the warp yarn, the area of the yarn per unit area of the base portion becomes large, and the yarn of the base portion and the pattern portion becomes large. The density difference is reduced and the pattern cannot be clarified. Further, when the thickness of the insertion yarn is less than 0.5 times the thickness of the warp, the ratio of the stretch yarn exposed to one side in the thickness direction of the knitted lace is reduced in the base portion, and the touch of the knitted lace is reduced. I can't do it well.
[0032]
Therefore, when the thickness of the insertion yarn is 0.5 times or more and 25 times or less of the thickness of the warp, the touch can be improved and the pattern can be made clear.
[0033]
In the present invention, a plurality of wales in which a plurality of loop-shaped portions are connected to each other by warp are formed substantially in parallel, and the wales adjacent to each other in the second direction orthogonal to the first direction in which the wale extends are mutually connected by the warp or the weft. A method of manufacturing a knitted lace with a patterned pattern to be connected,
An insertion yarn including a stretchable core yarn and a covering yarn wound around the core yarn is knitted into a loop-like portion in an extended state, and the insertion yarn is partially exposed facing one side in the thickness direction of the knitted lace.As well as
Stretch a stretchable yarn having elasticity from a natural state and stretch it into a loop-shaped portion by stretching it with a stretch amount larger than the stretch amount of the insertion yarn.This is a method for producing a patterned knitted lace.
[0034]
According to the present invention, the insertion yarn is knitted in the stretched state during knitting, so that the core yarn shrinks after knitting and the coated yarn is wound in a loose state on the core yarn. Since the insertion yarn faces one side in the thickness direction of the knitting lace and is partially exposed, the loose part of the covering yarn becomes a fluff that protrudes to one side in the thickness direction of the knitting lace so that the knitting lace has a raised state. Can be obtained.
[0035]
Therefore, the raised state can be formed in the knitted lace without separately raising after the knitting, and the number of steps in the production of the knitted lace can be reduced. Further, the knitted lace can be formed without fraying the knitted fabric caused by the raising process. In addition, since the napping process is not performed, the fine fibers scattered by the napping process can be eliminated.
[0037]
According to the present invention, the stretchable yarn is stretched with a stretch amount larger than the stretch amount of the insertion yarn, and is knitted into a plurality of loop-shaped portions. As a result, the insertion yarn and the stretchable yarn shrink after knitting, and the knitted lace shrinks due to the shrinkage force of the insertion yarn and further shrinks due to the stretchable yarn.
[0038]
Since the stretch yarn shrinks more than the insertion yarn, the wale in which the stretch yarn is knitted shrinks compared to the case in which only the insertion yarn is knitted. Since each wale is connected to each other in the second direction, when one wale shrinks, the wale adjacent to the wale in the second direction also shrinks.
[0039]
When the insertion yarn is knitted into the wale that is shrunk by the stretch yarn, the insertion yarn further shrinks than the insertion yarn itself shrinks in the first direction after knitting. As a result, the coated yarn is further separated from the core yarn and wound around the core yarn in a more loose state.
[0040]
Thereby, the protruding amount of the covering yarn protruding toward one side in the thickness direction of the knitted lace is increased, and the ring raising can be increased. By increasing the ring raising, the touch when touching the knitted lace can be further improved. Further, the stretchability of the knitted lace can be more reliably realized by knitting the stretchable yarn.
[0041]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a knitting organization chart showing an enlarged part of a knitted lace 1 according to an embodiment of the present invention. The knitted lace 1 includes a warp yarn 2, a weft yarn 3, an insertion yarn 4, an expansion / contraction yarn 5, and a pattern yarn 10, and a knitted fabric is knitted. The knitted lace 1 may be knitted with a floating yarn (not shown) for forming a floating pattern on the front side.
[0042]
The warp yarn 2 is chain stitched, that is, chain-knitted to form loop-shaped portions 6a and 6b. The loop portions 6a and 6b are connected to form the wale 7. A plurality of wales 7 extend in the first direction C, which is the lace knitting direction, and are formed side by side in the second direction W, which is a direction orthogonal to the lace knitting direction.
[0043]
More specifically, the knitted lace 1 is knitted by the warp 2 including the first loop-shaped portion 6a and the second loop-shaped portion 6b. The first loop-shaped portions 6a and the second loop-shaped portions 6b are alternately arranged and formed in a plurality of stages in the first direction C. As shown in FIG. 1, the second loop-shaped portion 6b1 is inserted into the first loop-shaped portion 6a0 of the first-stage front stage C1 from one side to the other side, and extends to the first-stage rear stage C2 to form the second loop-shaped section 6b1. The first loop portion 6a1 of the same stage as the portion 6b1 is inserted from the other side to the one side and extends to the first direction rear stage C2, and the first loop portion 6a2 of the second direction C2 of the second loop part 6b1 in the first direction rear stage C2. It continues to. The first loop-shaped portions 6a and the second loop-shaped portions 6b are alternately connected to form a wale 7 that is continuous in the first direction C. In this way, the wale 7 knitted by the warp 2 has a chain stitch structure.
[0044]
The fineness of the warp 2 is, for example, a multifilament having a denier of 50 denier or less, particularly 40 denier or less. When the warp 2 is thick, a good lace pattern cannot be formed, and it is preferable that the warp 2 is thin in order to form a lace pattern. Therefore, the fineness of the warp 2 is as thin as possible with a thickness that the warp 2 does not cut when used as a knitted lace product. Further, it can be realized by various fibers such as nylon, rayon, polyester and polypropylene.
[0045]
The wefts 3 are knitted by connecting the wales 7 arranged in the second direction W and inserting the second loop-shaped portions 6b of the two wales 7 adjacent in the second direction W, respectively. Actually, the weft 3 has a laterally swinging portion 3a extending from one wale to the other wale, and a knitted portion 3b inserted through the second loop-shaped portion 6b. A braided portion 3b is connected to both ends of the laterally swinging portion 3a, and two wales 7 arranged in the second direction W are connected by the weft yarn 3.
[0046]
In a space surrounded by the two laterally swinging portions 3a arranged in the first direction C and the wale 7 aligned in the second direction to which the laterally swinging portions 3a are connected, a thread is not disposed and the transparent portion that is inserted in the thickness direction of the knitted fabric is inserted. A hole 8 is provided. The shape of the through hole 8 is adjusted by selectively arranging the laterally swinging portion 3 b on the loop-like portion of the wale 7. As a result, the knitted lace 1 can form a lace pattern represented by the shape of the through holes 8.
[0047]
For example, the weft 3 is inserted into the four second loop-shaped portions 6b of one wale 7 and is alternately knitted, extends in the first direction C, and swings to the adjacent wale 7 adjacent to the second direction W. Then, the four second loop-shaped portions 6b of the adjacent wale 7 are inserted and alternately knitted to extend in the first direction C. Is inserted and knitted. A plurality of the wefts 3 extending in this way are knitted for each wale 7, whereby each wale 7 is connected. For example, the weft 3 passes through the second loop-shaped portion 6b from the side where the first loop-shaped portion 6a and the second loop-shaped portion at the same stage in the first direction are continuous toward the rear stage C2 in the first direction.
[0048]
The fineness of the weft 3 is as thin as possible with the thickness that the warp 2 does not cut, like the warp 2. For example, it can be realized by various fibers such as nylon, rayon, polyester, and polypropylene. For example, for the weft 3, a multifilament of 50 denier or less, particularly 40 denier or less is used.
[0049]
The patterned yarn 10 is a yarn for forming a patterned pattern on the knitted fabric. The handle yarn 10 is knitted by being inserted through a predetermined second loop-shaped portion 6b of the two wales 7 arranged in the second direction W. The handle yarn 10 extends in a substantially S shape and returns a plurality of diffractions. Specifically, the handle yarn 10 includes an extended portion 10a extending in the second direction W, and a folded portion 10b that extends in a substantially U shape at both ends and extends to the extended portion 10a, and the extended portion 10a and the folded portion 10b. Extend alternately. The folded portion 10b passes through the two second loop-shaped portions 6b adjacent to each other in the first direction C.
[0050]
The patterned yarn 10 is knitted into a loop-shaped portion corresponding to a predetermined portion for providing a patterned pattern. In the handle portion in which the handle yarn 10 is knitted, the through-hole 8 is reduced by the knitting of the handle yarn 10, and the yarn is formed densely. Moreover, the area | region where the pattern yarn 10 is not knitted has the large through-hole 8, and becomes a sparse base part of a thread | yarn. Therefore, when the pattern yarn 10 is partially knitted on the wale 7, a sparse region and a dense region are formed on the knitted fabric. The pattern shown is formed. The fineness of the handle yarn 10 is selected to be, for example, 30 denier or more and 1200 denier or less.
[0051]
The pattern yarn 10 is, for example, from the portion where the first loop-shaped portion 6a and the second loop-shaped portion 6b of the first-direction front-stage C1 are connected to the first loop-shaped portion 6a as it goes to the first-direction rear-stage C2. The second loop portion 6b that is the same step in the first direction is inserted through the first loop portion 6a. There may be a plurality of handle yarns 10.
[0052]
The insertion thread 4 includes a core thread 11 having elasticity and a covering thread 12 wound around the core thread 11. The insertion yarn 4 is knitted into the wale 7 in a stretched state during knitting and contracts after knitting. The insertion yarn 4 is knitted by alternately passing through the second loop portions 6 b of the wale 7 and extends in the first direction C. Thus, by inserting the insertion yarn 4 into the wale 7, the knitted fabric can be contracted in the first direction C after knitting, and the knitted fabric can be stretched in the first direction C. For example, as the insertion thread 4 moves toward the second stage C2 in the first direction, the first loop-shaped part 6a1 and the part 6c1 where the second loop-shaped part 6b0 of the first-direction front stage C1 continues to the first loop-shaped part 6a1 The second loop portion 6b1 that is the same step in the first direction is inserted into the first loop portion 6a1. For example, the insertion yarn 4 is knitted side by side on the wale 7 aligned in the second direction W.
[0053]
The insertion yarn 4 is formed with a portion exposed to one side in the thickness direction of the knitted lace 1 after knitting. One side in the thickness direction of the knitted lace 1 is, for example, the back side of the knitted lace 1, that is, the side in contact with the skin. Further, the coated yarn 12 preferably has a hygroscopic property. As a result, the knitted lace 1 has sweat absorbency when used in underwear, and can prevent stuffiness. Moreover, since the insertion thread | yarn 4 is formed along the wale 7, it does not block the through-hole 8, and does not impair the aesthetic appearance of the lace pattern formed by the through-hole 8.
[0054]
The core yarn 11 of the insertion yarn 4 is made of, for example, polyurethane elastic yarn, so-called spandex, and the covering yarn 12 is made of, for example, a spun yarn or a covering yarn which is a filament yarn, and is a natural fiber such as cotton and silk. Alternatively, chemical fibers such as nylon and polyester may be used. Moreover, the super extra fine fiber called a microfiber may be sufficient.
[0055]
The core yarn 11 used for the insertion yarn 4 can be expanded four times from the natural state, for example, and the insertion yarn 4 has a length that is 1.5 times or more and 3.5 times or less the length in the natural state. It is stretched and knitted into the wale 7.
[0056]
The stretchable yarn 5 is a stretchable yarn, for example, a polyurethane elastic yarn, so-called spandex is used. The stretchable yarn 5 is knitted in a stretched state during knitting and contracts after knitting. The stretchable yarn 5 extends in the first direction C by alternately passing through the second loop portions 6b of the wale 7. As described above, the stretch yarn 5 is knitted into the wale 7, so that the knitted fabric can shrink in the first direction C after knitting, and the knitted fabric can be further stretched in the first direction C.
[0057]
For example, as the elastic yarn 5 heads toward the rear stage C2 in the first direction, the first loop part starts from the part where the first loop part and the second loop part of the front stage C1 in the first direction continue to the first loop part. The second loop-shaped part having the same step in the first direction is inserted into the shaped part. That is, the stretchable thread 5 passes through the second loop-shaped portion in the same direction as the insertion thread 4. The stretchable thread 5 is inserted through the second loop portion in the opposite direction to the weft 3.
[0058]
The stretchable yarn 5 can be stretched, for example, 6 times from the natural state, and is stretched to a length of 1.5 times or more and 5 times or less of the length in the natural state and is knitted into the wale 7. The fineness of the stretchable yarn 5 is selected to be 70 denier or more and 280 denier or less in the natural state.
[0059]
Further, the stretchable yarn 5 is stretched by a stretch amount larger than the stretch amount of the insertion yarn 4 that is stretched and knitted from the natural state, and is knitted into the loop-shaped portion. The natural state is a state in which the tension is released from the yarn. The extension amount is, for example, the length of the yarn portion that is extended by extending the yarn portion per unit length in the natural state of the yarn. That is, the knitted stretch yarn 5 is knitted so that the stretch rate at which the knitted stretch yarn 5 shrinks is larger than the stretch rate at which the insertion yarn 4 shrinks after knitting. The insertion thread 4 is further contracted by the stretchable thread 5 from the state where the insertion thread 4 is contracted by the tension applied during knitting.
[0060]
For example, the stretchable yarn 5 is knitted with a length that is 1.2 times or more and 3 times or less than the length of the insertion yarn 4 knitted in the stretched state. Specifically, the insertion yarn 4 is supplied by 300 mm and the stretchable yarn 5 is supplied by 200 mm per rack where the knitting machine rotates 480 times. Further, for example, 350 mm of the insertion thread 4 and 190 mm of the stretchable thread 5 are supplied per rack.
[0061]
The knitted lace 1 has a pattern portion in which the pattern yarn 10 is knitted and a base portion in which the pattern yarn 10 is not knitted. The ground portion includes a first ground portion in which the insertion yarn 4 is knitted into a plurality of loop-shaped portions adjacent to the first direction C of the predetermined wale 7, and a plurality of adjacent portions in the first direction C of the predetermined wale 7. A second base portion in which the stretchable yarn 5 is knitted in the loop-shaped portion.
[0062]
The handle portion is knitted into the plurality of loop-shaped portions adjacent to the first direction C of the predetermined wale 7 and the plurality of loop-shaped portions adjacent to the second direction W of the predetermined wale 7. The stretch yarn 5 is knitted into the first pattern portion in which the handle yarn 10 is knitted and a plurality of loop-shaped portions adjacent to the first direction C of the predetermined wale 7, and the second direction W of the predetermined wale 7 And a second handle portion in which the handle yarn 10 is knitted in a loop-like portion adjacent to the handle portion.
[0063]
The predetermined wale serving as the base portion and the pattern portion is selectively determined depending on the pattern formed on the knitted lace, and is selectively determined according to the stretchability and the touch necessary for the knitted lace.
[0064]
For example, the insertion yarn 4 and the stretchable yarn 5 are alternately and repeatedly arranged in the second direction W and extend in the first direction C. The insertion thread 4 and the stretchable thread 5 are knitted through all the second loop-shaped parts constituting the wale 7. Moreover, the loop-shaped part into which the pattern yarn 10 is knitted is determined by the pattern to be formed.
[0065]
FIG. 2 is a view showing an enlarged photograph of the insertion thread 4, and FIG. 3 is a perspective view schematically showing the insertion thread 4 in an enlarged manner. 2 (1) and FIG. 3 (1) show the insertion thread 4 in the natural state, and FIGS. 2 (2) and 3 (2) show the insertion thread 4 when stretched. The insertion thread 4 includes a core thread 11 having elasticity and a covering thread 12 that winds the outer periphery of the core thread 11 in a coil shape. The covering yarn 12 is preferably thinner than the core yarn 11 and less stretchable than the core yarn 11.
[0066]
As shown in FIG. 3 (1), the covering yarn 12 is wound in a natural state at a position away from the outer peripheral surface of the core yarn 11 in the radial direction, and the core yarn 11 and the covering yarn 12 have a radius of the core yarn 11. It is provided with a gap H in the direction. Further, the covering yarn 12 is provided such that portions adjacent to each other in the axial direction of the insertion yarn 11 are provided with a gap L in the axial direction. In the natural state, the insertion yarn 4 is configured such that the core yarn 11 is wound in a state where the covering yarn 12 is loosened, and the core yarn 11 can be deformed in the radial direction and the axial direction. The natural state is a state in which the yarn is not tensioned and is not in a stretched or contracted state.
[0067]
The covering yarn 12 is less likely to expand and contract than the core yarn 11. Therefore, as the insertion thread 4 is stretched, the core thread 11 is stretched and the peripheral diameter of the covering thread 12 around which the core thread 11 is wound is reduced. As shown in FIG. 3B, the insertion yarn 12 extends to the elastic limit of the covering yarn 12 after the covering yarn 12 comes into contact with the core yarn 11 and then the covering yarn 12 is stretched.
[0068]
FIG. 4 is an enlarged perspective view schematically showing the insertion yarn 4 knitted in the loop-shaped portion, and FIG. 4 (1) shows a state in which the stretchable yarn 5 is not knitted in the loop-shaped portion. The insertion thread 4 is shown, and FIG. 4 (2) shows the insertion thread 4 in a state where the stretchable thread 5 is knitted in the loop-shaped portion.
[0069]
As shown in FIG. 4 (1), when the stretchable yarn 5 is not knitted, the insertion yarn 4 shrinks after knitting, and the insertion yarn 4 shrinks compared to the stretched state shown in FIG. 3 (2). At this time, the core yarn 11 is contracted, the covering yarn 12 is separated from the core yarn 11, and an interval H is generated between the outer peripheral surface of the core yarn 11 and the covering yarn 12. Thus, the covering yarn 12 is provided so as to be deformable in the radial direction and the axial direction of the core yarn 11, and the covering yarn 12 constitutes a so-called annular raising.
[0070]
The insertion thread 4 is knitted and locked in the loop-shaped part of the wale 7. The inserted thread 4 is prevented from recovering to a natural state by the locked portion. Further, when the stretchability of the covering yarn 12 is low, the insertion yarn 4 cannot be knitted in a high stretched state, and may not shrink sufficiently after knitting. Therefore, the insertion yarn 4 does not completely return to the natural state shown in FIG. 3 (1), and the core yarn 11 is in a state of being tensioned with a smaller tension than that during knitting.
[0071]
As shown in FIG. 4 (2), the stretchable yarn 5 is stretched by a stretch amount larger than the stretch amount of the insertion yarn 4 that is stretched and knitted from the natural state, and is knitted into the loop-shaped portion of the predetermined wale 7. As a result, the stretchable thread 5 contracts in the first direction C rather than the insertion thread 4. As a result, the knitted lace 1 contracts more than when only the insertion yarn 4 is knitted.
[0072]
Compared to the case where only the insertion thread 4 is knitted, the loop-shaped part of the wale 7 is further brought closer by the stretchable thread 5, and the insertion thread 5 locked to the loop-shaped part is further contracted. As a result, the insertion yarn 4 contracts more than when only the insertion yarn 5 is knitted. Therefore, the core yarn 11 further shrinks, the covering yarn 12 is further separated from the core yarn 11, and the interval H between the outer peripheral surface of the core yarn 11 and the covering yarn 12 is increased. As a result, the deformable portion of the coated yarn 12 becomes larger, and the ring raising becomes larger.
[0073]
FIG. 5 is a cross-sectional view showing the knitted lace cut along the line V-V in FIG. The insertion yarn 4 is knitted into the wale 7 in an extended state, and is formed in a state where the covering yarn 12 is loosened with respect to the core yarn 11 after knitting. Since the insertion yarn 4 is exposed in one thickness direction F of the knitted lace 1, the loosely coated yarn 12 is separated from the core yarn 11 and protrudes in one thickness direction F of the knitted lace 1. As a result, the coated yarn 12 becomes a plurality of deformable thin fibers protruding in the thickness direction F, that is, fluff.
[0074]
As the insertion yarn 4 is knitted into the knitted lace 1 in this way, the coated yarn 12 becomes fluffed in the thickness direction F, and the knitted lace 1 is formed with a so-called annular raised, and a raised state can be obtained.
[0075]
As described above, according to the knitted lace 1 of the embodiment of the present invention, the raised state is formed on the one side in the thickness direction by the insertion yarn 4 without using the floating yarn for forming the raised like the conventional technique. Can be obtained. When the knitted lace 1 is touched from one side in the thickness direction, it can be improved by touching the fuzz and deforming the fuzz. FIG. 6 is a view showing an enlarged photograph of one surface of the knitted lace 1, FIG. 6 (1) shows a handle portion, and FIG. 6 (2) shows a base portion. The insertion yarn 4 is provided in one wales and is knitted into both the base portion and the handle portion. Therefore, the area of the yarn per unit area is small, the raised portion can be formed even in the base portion where the touch will be lowered, and the touch can be improved satisfactorily over the entire one side in the thickness direction of the knitted lace 1. .
[0076]
Further, since the insertion yarn 4 is contracted with respect to the first direction C, the insertion yarn 4 is not greatly bent to one side in the thickness direction of the knitted lace 1 and does not become dense in the first direction C. As a result, even when the insertion yarn 4 is knitted into the base portion for forming the pattern, the area of the yarn per unit area of the base portion can be reduced. Therefore, even if the insertion thread 4 is knitted into both the handle portion and the base portion, the through hole in the base portion is formed in a sufficient size without being blocked. That is, without sacrificing the sense of sheer of the base part, it is possible to increase the density difference of the yarn between the pattern part and the base part, to clarify the contrast of the pattern, and to form a clear pattern it can. Further, since the deformation of the covering yarn 12 is regulated by the core yarn 11, even if the covering yarn 12 is deformed, the shape of the through hole can be maintained without largely changing, and a desired lace pattern can be maintained. it can.
[0077]
Moreover, when the covering yarn 12 has a hygroscopic property, it is possible to form a raised nap having a hygroscopic property, and the knitted lace 1 can improve the hygroscopic property in addition to the touch in one thickness direction. As a result, when the knitted lace 1 is provided as an undergarment, it is possible to absorb sweat and prevent the skin and the knitted lace from becoming steamed.
[0078]
Further, the fineness of the insertion yarn 4 including the covering yarn 12 and the core yarn 11 is selected to be 140 denier or more and 560 denier or less. The fineness of the coated yarn 12 is selected to be 30 denier or more and 300 denier or less. By setting the fineness of the covering yarn 12 within the above-described range, it is possible to form a fluff having a good touch.
[0079]
Further, the thickness of the insertion yarn 4 is set to be 0.5 times or more and 25 times or less of the thickness of the warp yarn 2. When the thickness of the insertion yarn 4 exceeds 25 times the thickness of the warp yarn 2, the area of the yarn per unit area of the base portion increases, and the density difference between the base portion and the handle portion decreases. The pattern cannot be clarified. When the thickness of the insertion yarn 4 is less than 1 times the thickness of the warp yarn 2, the ratio of the insertion yarn 4 exposed to one side in the thickness direction of the knitting lace 1 is reduced in the base portion. I can't feel it well. Therefore, when the thickness of the insertion yarn 4 is not less than 1 and not more than 25 times the thickness of the warp yarn 2, the touch can be improved and the pattern can be made clear.
[0080]
Furthermore, the stretchability of the knitted lace 1 can be improved by knitting the insertion yarn 4 into the wale 7. As a result, a product using the knitted lace 1 can freely expand and contract with respect to the unevenness, has elasticity, and can obtain a fit, and can prevent the knitted lace 1 from being bent.
[0081]
Furthermore, when the stretchable yarn 5 is knitted in a state in which the amount of expansion and contraction is larger than that of the insertion yarn 4, the elasticity is greater than when only the insertion yarn 4 is knitted. As a result, a better fit can be obtained, and bending of the knitted lace 1 can be more reliably prevented.
[0082]
Further, the amount of expansion / contraction of the insertion yarn 4 is limited by the covering yarn 12, whereas the expansion / contraction yarn 5 has a wide range of expansion amount in which the expansion / contraction yarn 5 can be knitted, and the expansion amount can be easily changed. It is possible to easily form the knitted lace 1 having different stretchability.
[0083]
In addition, the elastic yarn 5 is knitted in the loop-shaped portion arranged in the second direction W with respect to the plurality of loop-shaped portions into which the insertion yarn 4 is knitted, and the insertion yarn 4 and the elastic yarn 5 are alternately arranged in the second direction. Therefore, the insertion thread 4 can be reliably shrunk by the stretchable thread 5, and the ring raising of the insertion thread 4 can be enlarged.
[0084]
Further, the insertion yarn 4 is knitted by alternately passing through the second loop portions 6b. As a result, there are more places where the insertion thread 4 is locked as compared with the case where the insertion thread 4 is partially knitted through the second loop-shaped portion 6b with a gap, so that the insertion thread 4 is displaced or falls off due to external force. Is prevented. Even if the insertion thread 4 is broken, the insertion thread 4 with one end cut can be locked with a short length.
[0085]
FIG. 7 is a cross-sectional view showing a knitted lace manufacturing apparatus 30 that manufactures the knitted lace 1 of the present embodiment. The knitted lace manufacturing apparatus 30 includes a knitting unit 31 and a winding unit 32. The warp yarn 2, the weft yarn 3, the insertion yarn 4, the stretch yarn 5, the handle yarn 10 and the floating yarn 17 are supplied to the knitting portion 31, and the knitting race 1 is knitted by the knitting portion 31. The knitted lace 1 is wound up by the winding unit 32. The knitted lace manufacturing apparatus 30 also includes two stands 33a and 33b and four beams 34a, so that the yarns 2, 3, 4, 5, 10, and 17 are supplied to a plurality of reeds arranged in the knitting unit 31. 34b, 34c, 34d are arranged. The knitting lace manufacturing apparatus 30 includes a floating yarn stand 33a on which a floating yarn bobbin 35 is hung, and a patterned yarn stand 33b on which a patterned yarn bobbin 36 is hung. Supply the thread.
[0086]
The knitted lace manufacturing apparatus 30 has a warp beam 34a and a weft beam 34b around which the warp yarn 2 and the weft yarn 3 are wound, adjusts the tension of the yarn, and supplies the yarn to each kite. Further, the knitting lace manufacturing apparatus 30 is provided with an insertion yarn beam 34c and an expansion yarn beam 34d for knitting the insertion yarn 4 and the expansion yarn 5 having stretchability, and further provided with a feed roller and an automatic control device. Apply appropriate tension and feed the yarn. In this way, each bobbin and each beam supplies each yarn to each ridge of the knitting unit 31.
[0087]
Further, the knitted lace 1 formed by the knitting unit 31 is wound up by a winding unit 32 formed below the knitting unit 31. At this time, by knitting the insertion yarn 4 described above, it is possible to form the knitted lace 1 in which a raised state is formed on one side in the thickness direction without newly providing a raising device.
[0088]
FIG. 8 is an enlarged side view showing the knitting portion 31. The knitting portion 31 includes a plurality of ridges, and includes elastic ridges 41 and 42, a handle yarn fold 43, a floating yarn fold 48, a jacquard dropper bar 44, and ground rods 45 and 46. The warp yarn 2 is threaded through the ground rods 45 and 46, the weft yarn 3 is threaded through the jacquard dropper bar 44, and the insertion yarn 4 and the stretchable yarn 5 are threaded through the elastic rods 41 and 42, respectively. Further, the handle yarn 10 is passed through the handle yarn cage 43 and the float yarn 17 is passed through the float yarn cage 48. Each scissors are arranged in a radial pattern toward the position where the needle (needle) captures the yarn, from the front side to the rear side of the needle, in other words, from the upstream side to the downstream side in the direction in which the needle captures each yarn. The elastic yarn 41 for the insertion yarn, the elastic yarn 42 for the elastic yarn 5, the handle yarn rod 43, the jacquard dropper bar 44, the ground yarns 45 and 46, and the floating yarn yarn 48 are arranged in this order.
[0089]
In synchronism with the up-and-down movement of the needle, each heel performs overlap wrapping (knitting formation movement) that moves in front of the needle, that is, the hook portion forming side, and under wrapping (insertion movement) that moves behind the needle. In addition to these lapping motions, a so-called swing (oscillation motion) is made in which the needles move in a direction perpendicular to the direction in which a plurality of needles are arranged, that is, the needle rows, and the guides attached to the scissors pass between the needle rows. Thus, each yarn is given a yarn introduction action to an accurate stitch forming position. Further, the floating yarn 17 supplied to the needle from the floating yarn collar 48 can be shifted to a position where the stitch is not formed by the fall plate 47, whereby a floating pattern can be formed on the knitted fabric.
[0090]
The knitting portion 31 includes a needle bar 38 (hereinafter abbreviated as a needle) having a needle 39, a stitch comb bar 35, a trick plate 36, and a tongue 37. After each yarn guided from each heel to the needle is knitted as a knitted fabric by the operation of each heel and needle, the knitted fabric formed by the knitting assisting action of the stitch comb passes through the trick plate 36 and smoothly It is wound up.
[0091]
Since the insertion thread elastic rod 41 is disposed in front of the needle traveling direction forward (left side in FIG. 8) behind the knitting machine, the insertion thread 4 can be knitted on one side in the thickness direction of the knitting lace. Thus, the insertion yarn 4 can be partially exposed to one side in the thickness direction of the knitted lace 1. When the insertion yarn 4 is exposed, the coated yarn 12 forms a fluff protruding on one side in the thickness direction, and a raised state can be obtained.
[0092]
In addition, since the floating yarn collar 48 is arranged on the front side of the knitting machine (right side in FIG. 8) and behind the needle traveling direction, the floating yarn 17 can be knitted on the other side in the thickness direction of the knitting lace. Accordingly, a floating pattern can be formed by the floating yarn 17 on the other side in the thickness direction of the knitted lace.
[0093]
Accordingly, by setting one side in the thickness direction of the knitted lace 1 to the back side and the other side in the thickness direction to the front side, a raised state is obtained by the insertion yarn 4 on the back side of the knitted lace 1 and the yarn is floated on the front side of the knitted lace 1. The floating pattern can be formed by 17. For example, when used for underwear or the like, a brushed state can be obtained on the back side touching the skin, and a well-defined and clear pattern can be obtained. Further, the floating thread 17 can form a floating pattern on the front side, that is, a three-dimensional pattern protruding in the thickness direction.
[0094]
FIG. 9 is a cross-sectional view showing a chain stitch knitting cycle, and the knitting work of the loop 40 of the warp 2 proceeds in the order from FIG. 9 (1) to FIG. 9 (5). In the needle 39 for knitting each yarn, a hook portion 39a for hooking each yarn is formed at the distal end portion, and a needle stem 39b is formed on the proximal end portion side. Further, the tongue 37 is formed so as to close the opening formed in the needle 39 by the hook portion 39a. The needle 39 and the tongue 37 can be moved up and down toward each heel.
[0095]
In the chain stitch knitting cycle, first, as shown in FIG. 9 (1), the loop 40 of the warp 2 is locked by the hook portion 39 a of the needle 39, and the opening of the hook portion 39 a of the needle 39 is blocked by the tongue 37. Next, as shown in FIG. 9 (2), the needle 39 rises toward the ground 45, and the loop 40 of the warp 2 comes out of the hook portion 39a and moves to the needle stem 39b. Further, the ground 45 moves (under wraps) behind the needle 39 to the stitch formation position.
[0096]
Next, as shown in FIG. 9 (3), the ground 45 moves toward the front of the needle 39 (back swing) and moves in front of the needle 39 so as to be hooked on the hook portion 39 a of the needle 39 (overlap). To do.
[0097]
Next, as shown in FIG. 9 (4), the ground 45 moves so as to wind the needle 39 (front swing), and the loop 49 of the new warp 2 is locked to the hook portion 39a. Also, the tongue 37 rises toward the hook portion 39a and closes the opening of the hook portion 39a. At this time, the needle 39 is formed with an old loop 40 formed on the needle stem 39b and a new loop 49 to which the hook portion 39a is locked.
[0098]
Next, as shown in FIG. 9 (5), when the needle 39 and the tongue 37 are simultaneously lowered, the old loop 49 is moved toward the trick plate 36, and the new loop 40 is locked by the hook portion 39a of the needle 39. Then, the operation of FIG. 9 (1) is performed again. By repeating such a cycle, a chain stitch is formed. At this time, the knitted fabric can be knitted by knitting other yarns simultaneously.
[0099]
The needle 39 is a second loop-shaped portion 6b, and the floating yarn 17, the handle yarn 3, the stretch yarn 5, and the insertion yarn 4 are locked in this order, so that the insertion yarn 4 is knitted and inserted closer to one side in the thickness direction. A portion where the yarn 4 is exposed facing one side in the thickness direction can be formed. Further, the floating yarn 17 can be knitted on the other side in the thickness direction to form a floating pattern.
[0100]
As described above, the insertion yarn 4 is knitted into the wale 7 in an extended state, and in the order in which the needle 39 engages the yarn with the second loop-shaped portion 6b, the order of capturing the insertion yarn 4 is the last or close to the last. By making the order, a portion where the insertion yarn 4 is exposed from one side in the thickness direction of the knitted lace can be formed, and fluff protruding from one side in the thickness direction of the knitted lace can be formed. Therefore, the raised state can be formed in the knitted lace without performing the raising process after knitting, and the number of steps in manufacturing the knitted lace can be reduced. Moreover, since the raising process like the said prior art is not performed, the fraying of the knitting lace which arises by a raising process can be eliminated, and a knitting lace can be formed. Moreover, the scattering of the fine fiber which arises by a raising process can be eliminated.
[0103]
FIG.0FIG. 1 is a structure diagram schematically showing the structure of warp yarn 2 and insertion yarn 4;0(1) shows the structure of the warp 2 and FIG.0(2) shows the structure of the insertion thread 4. FIG.0As shown in (1), for example, the ground 45 performs the following operations. The knitting operation is performed, and the course proceeds to the first to eighth courses arranged in order in the first direction.
[0104]
In the first course C1, the back swing is performed through the first inter-needle L1 and the front swing is performed by overlapping the second inter-needle L2. Next, in the second course C2, underlap is performed at the third inter-needle L3, backswing is performed through the third inter-needle L3, and overlap is performed and a front swing is performed through the second inter-needle L2. In the third course, the L2 overswing between the second needles is overlapped, and the front swings through the third L3 between the needles by overlapping. In the fourth course C4, the third inter-needle L3 back swing is performed, and the front swing is performed by passing through the second inter-needle L2. In the fifth course C4, an operation similar to that of the third course C3 is performed, and in the sixth course C6, an operation similar to that of the fourth course C4 is performed.
[0105]
In the seventh course C7, the L2 overswing between the second needles is overlapped, and the front swing is performed by passing through the third L3 between the needles. In the eighth course C8, underlap is performed to the second inter-needle L2, backswing is performed at the second inter-needle L2, and overlap is performed and the front swing is performed through the first inter-needle L1. Next, the same operation as the first course C1 is repeated. As described above, the ground yarn 45 repeats the operations performed in the first to eighth courses, whereby the warp 2 is formed with a plurality of loops and a horizontal swing portion that moves in the second direction W. .
[0106]
FIG.0As shown in (2), the elastic rod 41 for insertion thread performs a back swing and a front swing at the second course L2 in the first course C1. Next, in the second course C2, underlap is performed up to the first needle interval L1, and a back swing and a front swing are performed in the first needle interval L1. In the third course C3, underlap is performed in the second inter-needle L2, and the back swing and the front swing are performed in the second inter-needle L2. Next, in the fourth course C4, the operation of the second course C2 is performed. Thus, the operations performed in the first to second courses are repeated, and the insertion yarn 4 is knitted into the loop formed in the warp 2 by being performed simultaneously with the knitting of the warp 2 described above. Furthermore, the handle yarn 10 and the floating yarn 17 are knitted into the loop of the warp yarn 2.
[0114]
FIG.1These are the knitting | organization organization chart which shows a part of the knitted lace 110 of further another embodiment of this invention. The knitted lace 110 is different from the knitted lace 1 shown in FIG. 1 in the knitting of the insertion yarn 4 and the stretchable yarn 5, and the insert yarn 4 and the stretchable yarn 5 are knitted into all the wales 7. About this other structure, it is the same as that of the knitted lace 1 shown in FIG. 1, About the same structure, description is abbreviate | omitted and the same code | symbol is attached | subjected.
[0115]
In the knitted lace 110, both the insertion yarn 4 and the stretch yarn 5 are knitted into one wale 7. The insertion thread 4 and the stretchable thread 5 are knitted in all the loop-shaped portions of each wale 7. As the insertion yarn 4 heads toward the rear stage C2 in the first direction, the second loop-shaped portion starts from the portion where the first loop-shaped portion and the second loop-shaped portion in the same stage in the first direction with respect to the first loop-shaped portion are connected. Is inserted through the second loop-shaped portion in the same stage in the second direction.
[0116]
For example, as the elastic yarn 5 heads toward the rear stage C2 in the first direction, the first loop-like part is formed from a part where the first loop-like part and the second loop-like part 6 in the first-direction first stage are continuous with the first loop-like part. The first direction same-stage C1 second loop-shaped part is inserted into the part.
[0117]
That is, the stretchable yarn 5 is knitted into the second loop-shaped portion from the opposite side with respect to the insertion yarn 4 inserted through the same second loop-shaped portion. The knitted lace 110 can obtain the same effect as the knitted lace 1 shown in FIG.
[0118]
The above description is merely an example of the present embodiment, and the configuration may be changed within the scope of the invention. For example, the coated yarn 12 can form brushed hair having moisture absorption on the surface of the knitted lace that contacts the skin by using a yarn having moisture absorption such as cotton yarn. Alternatively, microfibers that are ultrafine fibers may be used. Moreover, you may change the twist condition of such a covering yarn. Further, the knitted lace structure shown in the embodiment is merely an example, and the manner of hanging each thread and the tension balance may be changed. Furthermore, the knitted lace of the present invention may be manufactured by an apparatus different from the knitted lace manufacturing apparatus 30 shown in FIG.
[0119]
【The invention's effect】
According to this invention of Claim 1, a fluff can be formed in the thickness direction one side of a knitted lace, and the touch can be improved. Moreover, since the amount of yarn per first direction of the insertion yarn forming the fluff does not increase, the density difference of the yarn between the base portion and the handle portion can be clarified, and the pattern pattern can be clearly expressed.
[0120]
MaBookAccording to the invention, the protruding amount of fluff formed on one side in the thickness direction of the knitted lace can be increased. This can further improve the touch. Further, the stretchability in the first direction of the knitted lace can be more reliably provided.Furthermore, by changing the extension amount of the stretchable yarn knitted into the knitted lace, a knitted lace having different stretchability can be easily formed regardless of the extension of the insertion yarn.
[0121]
Further, according to the third aspect of the present invention, it is possible to improve the touch and to impart moisture absorption to the fluff.
[0122]
According to the fourth aspect of the present invention, the thickness of the insertion yarn is determined to be not less than 0.5 times and not more than 25 times the thickness of the warp, so that the knitted lace has a good texture and a clear pattern. Can be formed satisfactorily.
[0123]
Further, according to the present invention, it is possible to produce a knitted lace with raised hairs without the need for raising treatment, so the number of steps can be reduced and the production cost can be reduced. Further, since the raised hair can be formed only by knitting the insertion yarn into the wale, it is not necessary to remodel the manufacturing apparatus significantly, and the knitted lace can be manufactured using the conventional knitting lace manufacturing apparatus. Further, since the raising treatment is not performed, it is possible to prevent the caught fibers from scattering.
[0124]
MaBookAccording to the invention, the protruding amount of fluff formed on one side in the thickness direction of the knitted lace can be increased. This can further improve the touch. Further, the stretchability in the first direction of the knitted lace can be more reliably provided.
