BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lace knitted fabric, which is represented by Raschel knitting, provided with a plurality of wales formed of loop-shaped warps, and more specifically, stretchability is imparted in the longitudinal direction of the wales. Regarding lace knitting.

[0002]

2. Description of the Related Art Conventionally, a lace knitted fabric is a lace knitted fabric formed by knitting yarns, and by utilizing the fact that it has some elasticity, the wale of a part or all of the knitted fabric of the lace is used. In another, there is a lace knitted fabric in which a stretchable yarn having elasticity such as a rubber yarn is knitted to give elasticity and stretchability in the longitudinal direction over the entire length. An example of a Raschel knitting machine, which is a kind of lace knitting machine for knitting such a lace knit, is shown in FIG. The Raschel knitting machine 20 includes a knitting portion 24 for knitting the lace knitted fabric, a roll 25 for winding the knitted fabric 10 knitted by the knitting portion 24, a warp yarn 2 and a weft yarn 5 in the knitting portion 24.
Ground beam 2 for supplying ground yarns 11 made of
1 and an elastic yarn beam 22 for supplying the elastic yarn 4 to the knitting portion 24 for knitting into the warp yarn 2 and the ground yarn 11 for forming the pattern of the knitted fabric 10 for knitting The knitting portion 24 is composed of a handle beam 23 for supplying the handle yarn 6a. In the knitting section 24, a plurality of reeds having guides for guiding the ground yarn 11, the elastic yarns 4, the pattern yarns 6a, etc., a large number of knitting needles for chain-knitting the warp yarns 2, and a large number of the knitting needles are vertically arranged. A needle hook or the like for leading is provided (not shown), and the knitted portion 24 forms the lace knitted fabric 10 and is wound around the winding roll 25. A single course 7 is formed by one reciprocating operation of the knitting needle up and down to form the loop 3 of the wale 1, but detailed description thereof will be omitted. FIG. 5 shows an example of the lace knitted fabric 10 wound around the winding roll 25. Each warp yarn 2 of the ground yarn 11 is chain-knitted by one operation of the plurality of knitting needles to form a plurality of wales 1. Between the needle loop portion 3a and the sinker loop portion 3b of the loop 3, a weft yarn is formed. 5 is inserted to connect the wales 1 to form a ground portion 12. In the knitted ground portion 12 of the base yarns 11, through holes 14 having different shapes are formed depending on the course pitch into which the weft yarns 5 are inserted. The elastic yarn 4 is conventionally the needle loop portion 3a.
Between the sinker loop portion 3b and the weft yarn 5, one yarn is inserted along each of the wales 1 and knitted. A necessary tension is applied to each yarn 11 to be knitted. However, the elastic yarn 4 is knitted in a stretched state with a large degree of elongation, and the elastic stretchability of the elastic yarn 4 is utilized to make the lace knit 10 substantially uniform over the entire length. Stretchability is given. Furthermore, a handle thread 6 is provided between the needle loop portion 3a, the weft thread 5 and the elastic yarn 4, and the sinker loop portion 3b.
The insertion thread 6 such as a is inserted and knitted, and the pattern thread 6
A handle portion 13 having a handle formed by a is formed. The ground yarn 11 and the insertion yarn 6 are knitted together with the stretchable yarn 4 in the stretched state of the stretchable yarn 4, and the course in the machine (that is, the state in which the lace is knitted in the lace knitting machine) The width (the length of the loop formed by knitting one course) is constant, and the product (the lace knitted fabric removed from the lace knitting machine) has a long length of the wale 1 due to the elastic restoring force of the elastic yarn 4. It is in a state of being restored and contracted in the direction, and can be extended substantially uniformly up to the length at the time of knitting.

[0003]

In the conventional lace knitted fabric, the elastic yarn 4 is knitted in the wale 1 in the stretched state on the machine (that is, the state in which the lace knitted fabric is knitted on the lace knitting machine). Although the elastic contraction of the elastic yarn 4 due to elastic recovery is imparted in the longitudinal direction, this elastic contraction is uniform over the entire length.
Therefore, it is not possible to use a continuous elastic lace knitted fabric to serve to tighten only a local part such as a girdle, and it is possible to sew the lace knitted fabric only to the necessary part, which is aesthetically pleasing. There was a problem that it was not excellent. Therefore, an object of the present invention is to solve the above-mentioned problems, to sew a continuous lace knitted fabric and to decorate it, and at the same time, to impart a restoring shrinkage property only to a required local part, and only a main part is required. The purpose is to provide a lace knit that can be stretched, restored, and tightened at key points.

[0004]

[Means for Solving the Problems]

[Feature Means] The feature means of the present invention for the above purpose is
In a single operation cycle of the lace knitting machine, a plurality of warp yarns are chain-knitted to form a course in which a plurality of loops are arranged side by side, the courses are continuously formed in the longitudinal direction, and a plurality of wales are knitted at the same time. Stretching yarns are knitted into at least a part of each of the wales, and a plurality of types of the course groups to be continuously knitted are formed, and knitting is performed with different degrees of extension for stretching the stretchable yarns in each of the plurality of types of course groups. (Corresponding to claim 1). [Effects of Characteristic Means] Therefore, according to the above-described characteristic configuration, the elastic yarn is stretched on the machine (that is, the state in which the lace knitting is knitted on the lace knitting machine) (that is, the elastic yarn is stretched from other yarns By knitting (giving a large degree of stretch), when the stretchable yarn is greatly stretched, the stretchable yarn shows a large elastic restoring force. Therefore, the wale in which the stretchable yarn is woven has an elastic restoration of the stretched stretchable yarn. A large restoring shrinkage force is applied by the force, and this restoring shrinkage force becomes small when the degree of extension is small. Therefore, knitting a lace knitted fabric having different restoring shrinkage forces when stretched in the longitudinal direction by the longitudinal portion. You can As a result, for example,
As for elastic lace knitting that can be sewn on the girdle also as decoration, it can be used without replenishment while exhibiting different tightening force at different parts, and a lace knit that can be used for girdle with excellent appearance It will be possible to provide. [Additional Means 1 and Actions and Effects] In addition, while forming two kinds of course groups knitted in the characteristic means, in one of the formed first course groups, the elastic yarn is elongated, or without elongation, The other of the formed second
In the course group, the elastic yarn may be stretched and knitted with a greater degree of elongation than the first course group (corresponding to claim 2), and in this way, the elastic yarn is extended. As a result, a restoring shrinkage force is applied to the wale, so that restoring shrinkage is imparted or not imparted in the first course group, and is greater in the second course group than in the first course group. It is possible to knit a lace knitted fabric to which restoration shrinkage is imparted, and it is possible to knit a lace knitted fabric suitable for a purpose of giving a tightening force only to a main part. As a result, for example, it becomes possible to provide a lace knitted fabric that can be given a desired decoration while applying a tightening force only to a necessary portion of the girdle. [Additional Means 2 and Effects] On the lace knitting machine, the course width in the second course group, which constitutes the additional means 1, is knitted larger than the course width in the first course group. (Corresponding to claim 3) It is better to do so. In this way, the knitted lace knitted fabric has the above-mentioned course width (that is, the course interval on the machine, that is, the race winding drum of the race knitting machine). It can be extended up to the winding amount), and the different degree of expansion and contraction between the first course group and the second course group (that is, from the state in which the lace knit is left to be pulled in the longitudinal direction). It is possible to add the degree of change in the length of the lace knitted fabric) to the lace knitted fabric. Therefore, since the restoring contraction force is applied by the elastic restoring force of the elastic yarn, the restoring contraction force is determined by the extent to which the elastic yarn is stretched, and when the elastic member is stretched beyond the limit of the elasticity of the small course width portion. As a result, only the portion of the large course width is further stretched, so that the stretched lace knitted fabric exhibits a large restoring shrinkage property in the portion of the large course width, and partially exhibits different restoring shrinkage properties. When used for decoration such as underwear, it does not have openings for parts that you want to give elasticity (for example, the chest part of the neckline of the underwear or the side parts of the waist), so use fasteners or hooks. It is suitable for knitting a lace knitted fabric suitable for use in lace decoration without stopping.
As a result, for example, it becomes possible to knit a lace knitted fabric that is capable of adjusting the tightening force while applying a desired decoration while applying the tightening force only to necessary parts of underwear such as a girdle or clothing. When the lace knitted fabric knitted by the present means is applied to a garment that is sewn using a lace knitted fabric at the waist portion, a portion having a large stretchability of the lace knitted fabric is arranged on the side part, or By arranging and sewing a large stretchable part of the lace knit on the back, it is possible to make clothes that can be easily put on and taken off without providing side openings or back openings, and it is possible to improve the appearance of the clothes as well. . [Additional Means 3 and Actions] Then, the first course group and the second course group, which compose the additional means 1 or 2, are knitted alternately (corresponding to claim 4). Even better, this makes it possible to alternately arrange portions having different restoring shrinkage properties in the lace knitted fabric. As a result, for example, when used for a girdle, by arranging parts having different restoring and contracting properties according to the size, while applying a tightening force only to a necessary part, a desired decoration is applied and at the same time. It becomes possible to knit a lace knitted fabric with adjustable tightening force. [Additional Means 4 and Operational Effects] Furthermore, elastic yarns may be woven into all of the plurality of wales described in the characteristic means or the additional means 1 to 3 (corresponding to claim 5). Even better, by doing so, it is possible to knit the lace knitted fabric having the above-described stretchability that is different partially or partially depending on the entire width of the lace knitted fabric. As a result, for example, when it is used for a girdle, it is possible to knit a lace knitted fabric that also serves as a decoration so that a sufficient tightening force can be applied only to a necessary portion by knitting an elastic yarn having a large elastic restoring force.

[Characteristic Configuration] In the characteristic configuration of the present invention for the above purpose, a plurality of wales formed in the longitudinal direction of chain-knitted warps are provided, and a plurality of loops of the plurality of warps are arranged side by side. In a lace knitted fabric in which courses are continuously formed in the longitudinal direction, knitting a stretchable yarn into at least a part of each of the plurality of wales, and knitting a plurality of types of the course groups continuously formed in the longitudinal direction. The plurality of types of course groups have different restoration contractility due to elastic restoration of the woven elastic yarn when stretched in the longitudinal direction (corresponding to claim 6). [Operation and Effect] Therefore, according to the above-mentioned characteristic configuration, each of a plurality of types of course groups continuously formed in the longitudinal direction is made to have different restoring shrinkability provided when the woven elastic yarn is extended in the longitudinal direction. Therefore, the wale in which the elastic yarn is knitted is provided with the different restoring shrinkage depending on each course group, and due to the difference in the restoring shrinkage, the knitted lace has different restoring shrinkage depending on the longitudinal portion. When used for decoration such as underwear, this does not require opening in the part where elasticity is to be given (for example, the chest part of the neckline of the underwear, the side part of the waist, etc.), and therefore without the need for hooking. A lace knitted fabric suitable for use in lace decoration. As a result, for example, even if you want to exert different tightening force in different parts, such as a lace decoration that can be sewn on the girdle also as a decoration, it can be used without adding a lace knit,
It becomes possible to provide a girdle with an excellent appearance. In addition, when applying the lace knit of this characteristic configuration to the garment that is sewn using the lace knit on the waist part, dispose a part of the lace knit having a large stretchability on the side part or the back part. By arranging and sewing a portion of the lace knitted fabric having a large elasticity, it is possible to make the garment easy to put on and take off without providing the side opening or the back opening, and it is also possible to improve the appearance of the garment. [Additional Configuration 1 and Operation and Effect] It is sufficient that all the plurality of wales in the characteristic configuration are knitted with the elastic yarn (corresponding to claim 7), and thus, the entire width of the lace knitted fabric can be obtained. Restoration shrinkability different from each other as described above is imparted to the entire area. As a result, for example, when it is used for a girdle, if a stretchable yarn having a large elastic restoring force is knitted, a sufficient tightening force can be applied only to a necessary portion, and at the same time, it can also serve as decoration. [Additional Configuration 2 and Operation and Effect] Further, two kinds of the course groups continuously formed in the vertical direction according to the characteristic configuration are formed, and one of the formed first course groups and the other second course group are formed. It is all right if knitting and knitting are alternately repeated, or the additional constitution 1 is added thereto (corresponding to claim 8), and in this way, the lace knitted fabric has different restoring shrinkability. The parts are arranged alternately. As a result, for example, when it is used for a girdle, if the lace knitted fabric is provided with parts having different restoring contraction forces according to its use and size, a desired decoration can be obtained while applying a tightening force only to necessary parts. At the same time, the tightening force can be distributed as desired, which is aesthetically pleasing and
It is possible to provide a girdle that can effectively tighten the body. Further, when used for underwear or the like made of tricot having elasticity as a whole, it becomes possible to provide underwear having an excellent aesthetic appearance without using collar opening, zipper fastening at the side, or hook fastening. [Additional Configuration 3 and Operation and Effect] In the first course group according to the additional configuration 2, the second course is provided without imparting the restoring shrinkability by the woven elastic yarn.
In the course group, so as to give the above-mentioned restoration contractility,
It is even better if the elastic yarn is knitted into the wale (corresponding to claim 9). In this way, the first course group does not have the restoring shrinkage property, and the second course group does the restoring step. The lace knitted fabric has shrinkability and is partially restored and shrinkable, which is suitable for application of stretchability or tightening force only to a main part. In particular, if the elastic restoring force of the stretchable yarn to be knitted is changed in the width direction of the lace knit, the lace knitted fabric will be curved at the stretchable portion. As a result, for example, when it is used for a girdle, it is possible to apply a desired decoration while applying a tightening force only to its necessary portion, and for underwear or the like that does not have much elasticity as a whole. When using it, do not distribute the fabric to the part that uses the collar opening, side hooks, etc., but instead of this part fabric, place a stretchable part of this lace knit, and you will have an excellent underwear Will be able to provide.

Embodiments of the present invention will be described below with reference to the drawings. One embodiment of the characteristic structure to which the characteristic means of the present invention is applied will be described below. FIG. 1 shows the knitting section 24 of the Raschel knitting machine shown in FIG.
The portion of the on-board race 10a wound on the roll 25 is schematically shown, and the warp yarn 2 and the insertion yarn 6 are omitted. Although the drawing of the Raschel knitting machine used in the present invention is omitted, it has the same configuration as that of FIG. 4, and the stretchable yarn 4 between the stretchable yarn beam 22 and the knitting portion 24 passes through tension adjusting means (not shown). It is characterized in that it is being sent to the knitting section 24. The lace knitted fabric 10 has a general structure as shown in FIG. Regarding the ground portion 12, the handle portion 13 and the through hole 14 of the lace knitted fabric 10, as in the case of the conventional lace fabric,
Loops 3 formed by warp yarns 2 constituting a large number of wales 1
The weft yarn 5 is inserted between the needle loop portion 3a and the sinker loop portion 3b, and the wale 1 is connected to form a gland portion 12. These warp yarn 2 and weft yarn 4
The knitted ground portion 12 of the through hole 1 having a different shape depending on the change of the course pitch or the like into which the weft thread 5 is inserted.
4 are formed. Furthermore, the needle loop portion 3
a and the elastic yarn 4 and the sinker loop portion 3b, the weft yarn 5 and the insertion yarn 6 such as a handle yarn 6a are inserted and knitted, and a handle portion in which a handle is formed by the handle yarn 6a 13 is formed. Elastic yarn 4 made of rubber yarn
Is knitted by inserting it along the wale 1 between the needle loop portion 3a and the sinker loop portion 3b, the weft yarn 5, the insertion yarn 6 and the like. That is, while the other yarns have the same degree of elongation while being knitted by changing the winding speed of the roll 25 by the longitudinal portion of the lace knitted fabric 10, the rubber yarn 4 has a greater degree of elongation than the other yarns. The warp yarn 2, the weft yarn 5 and the handle yarn 6a are knitted in the stretched state, and the warp yarn 2, the weft yarn 5 and the handle yarn 6a are knitted together with the rubber yarn 4 in the stretched state. The lace knit 10 is used to give elasticity. That is, when a tensile force is applied to the lace knitted fabric 10 in the longitudinal direction, the rubber yarns 4 are stretched, and as a result, the elastic restoring force of the rubber yarns 4 is exerted on each wale 1, so that the lace knitted fabric 10 is At the same time as it expands, it will exert a restoring contraction force. The rubber thread 4
Is composed of a first rubber thread 4a and a second rubber thread 4b. The first rubber thread 4a is the needle loop portion 3 of the loop 3, respectively.
a and the sinker loop portion 3b are all inserted and knitted, and the second rubber thread 4b is partially inserted between the needle loop portion 3a and the sinker loop portion 3b of the loop 3 respectively. It is woven. Therefore, in the loop 3, the first and second rubber threads 4a and 4b are both inserted along the same direction, the one is crossed and the first rubber thread 4a only. Some have been inserted. Therefore, when heat is applied in the finishing stage of the race, the first and second rubber threads 4a, 4a, 4b are inserted in the loop 3 where both the first and second rubber threads 4a, 4b are inserted. 4b are partially fused to each other, and the position of the wale 1 in the gland portion 12 is restricted in the longitudinal direction. As a result, both the rubber threads 4a and 4b will not fall into the race even when cut at the longitudinal end of the race. Further, as described above, some of the loops 3 have only the first rubber thread 4a inserted therein. Therefore, at least in these loops, the insertion thread is inserted with a margin in the loops described above. Therefore, it is possible to give the lace sufficient elasticity.

FIG. 1 schematically shows the on-board race 10a between the knitting section 24 and the roll 25. The rubber thread 4 does not show the weaving method and the number of threads, and the ground thread 11 Only the warp yarns 2 are shown, and the lace knitted fabric 10 is provided with a rigid zone R (that is, a region having almost no stretchability) constituted by the first course group 8 which is not imparted with the restoration shrinkage property and the restoration knitting property. A stretch zone S (that is, a region having large stretchability) configured by the second course group 9 is continuously and repeatedly arranged. The weft yarn 5, the insert yarn 6 and the like (not shown) are knitted at the same course pitch in both the rigid zone R and the stretch zone S. The course width 15b in the stretch zone S is equal to the course width 15 in the rigid zone R.
It is larger than a, and the restoring shrinkage allowance of the rubber thread 4 is large. By changing the course width 15 in this manner, the restoring shrinkability in the length direction of the lace knit 10 is changed. Furthermore, the rigid zone R
In the above, the rubber thread 4 is given the same degree of elongation as the degree of elongation of the other yarns such as the ground thread 11, but in the stretch zone S, the degree of elongation is changed as the course width 15 changes. It is changed, and a large degree of elongation is given to the rubber thread 4. With this structure, the lace knitted fabric 10
In the product state, the loop 3 has the course width 15
Therefore, in the rigid zone R, the rubber thread 4 stretches the lace fabric in the stretched state (the course width 1
5a), but in the stretch zone S, the course width can be extended up to about 15b, so that the lace knitted fabric is partially stretchable. In addition, as shown in FIG.
If both rubber threads 4a and 4b are woven so as to cross each other at the insertion position into the wale 1, it becomes difficult for the both rubber threads 4a and 4b to move relative to the loop 3 as described above. It is possible to prevent movement between R and the stretch zone S,
S can be reliably formed. In FIG. 1, the weft thread 5,
Illustration of the insertion thread 6 and the like is omitted, and the number of courses of the second course group 9 is smaller than the actual number.

FIG. 4 shows a method of knitting the above-mentioned lace knitted fabric.
The detailed explanation will be given with reference to FIG.
However, the rubber yarn 4 is fed from the elastic yarn beam 22 to the knitting portion 24 via the tension adjusting means (not shown). Although the specific configuration of the tension adjusting means is omitted, the elastic yarn beam 22
To the knitting portion 24, the path length of the rubber thread 4 can be changed. That is, since the extension degree is applied to the rubber thread 4 by the difference between the feeding speed of the rubber thread 4 from the elastic yarn beam 22 and the winding speed of the drum 25 that winds the lace knitted fabric 10, Course width 1
Since 5 is determined by the winding amount of the drum 25 for one course, the elastic yarn beam 22 is controlled in association with the feeding speed from the drum 25. If the length of the route to the knitting section 24 is constant, the rubber thread 4 is moved during the transition from the rigid zone R to the stretch zone S and during the transition from the stretch zone S to the rigid zone R. Since there is a large delay in the change in the elongation to be added to, the tension adjusting means is used in order to reduce this delay. This tension adjustment is performed by changing the path length from the elastic yarn beam 22 to the knitting portion 24. This is, for example, by providing a plurality of guides, forming a path of the rubber thread 4 in a path passing through each guide, and by relatively moving these guides,
The path length of the rubber thread 4 passing through these guides can be changed. That is, at the time of transition from the rigid zone R to the stretch zone S, the path length is lengthened until a desired extension force is reached, and at the time of transition from the stretch zone S to the rigid zone R. , The path length is restored. For example, the change of the path length is performed in about 3 seconds (for example, during formation of about 10 courses). By doing so, it is possible to obtain a lace knitted fabric whose stretchability is continuously changed within a very narrow width. FIG. 3 is a diagram illustrating elasticity of the lace knitted fabric 10 knitted in this way.
It was shown to. In the figure, (a) shows the outer shape of the product, that is, the lace knitted fabric 10 in a state of being naturally left, and (b) shows the outer shape of the lace knitted fabric 10 pulled in the longitudinal direction. In addition, the external shape is shown in a simplified manner to make it easier to understand the change in shape, and the pattern on the lace is not shown.
In the state of (a), there is no pattern difference between the rigid zone R and the stretch zone S, and in the state of (b), the rigid zone R hardly changes, whereas the stretch zone S does not change. While extending in the pulling direction, the pattern also extends in the longitudinal direction.

Next, another embodiment of the present invention will be described. <1> In the above-described embodiment, two elastic yarns 4 are knitted in the same wale, but the number of elastic yarns is arbitrary and may be one or three. It may be more than. <2> In the above-described embodiment, the elastic yarn is shown as partially crossed at the weaving position into the wale, but this is a preferred embodiment and it is not crossed at all insertion positions. Alternatively, it may be woven without being crossed. Further, one elastic yarn is inserted into each loop, and the other elastic yarn is intermittently inserted into the loop, but both of them may be inserted into all the loops. Both may be inserted into the loop intermittently. <3> In the above-mentioned embodiment, the elastic yarn is shown as being inserted in all wales, but it may not be inserted in a part of the wales. It may be inserted in the wale. Further, both elastic yarns to be inserted have the same elastic restoring force,
Elastic yarns having different elastic restoring forces may be inserted into each wale. If the restoring shrinkage force applied to each wale by the elastic restoring force of the stretchable yarn is inclined in the width direction of the lace knitted fabric, a laced knitted fabric having a curved shape in the stretch zone can be obtained. <4> In the above-described embodiment, the lace knitted fabric having the two parts formed of the stretch zone 15b made of the second course group 9 and the rigid zone 15a made of the first course group 8 is shown. Even when two types of regions are provided, the first course group 8 may be imparted with a restoring shrinkage property to form another stretch zone, and a lace knitted fabric composed of two regions having different restoring shrinkage properties, Also,
The area may be divided into three or more areas to form a lace knitted fabric in which different areas have different restoring shrinkage properties. <5> In the above-described embodiment, the course width on the machine is made different between the stretch zone 15b and the rigid zone 15a, but this is a preferred embodiment, The course width does not have to change. Further, instead of the rigid zone 15a, a stretch zone having a smaller restoring shrinkage than the stretch zone 15b may be formed. <6> In the above-described embodiment, an example in which the stretch zones 15b and the rigid zones 15a are alternately and continuously arranged to form a lace knitted fabric has been described. Rigid zone 15a
And the stretch zone 15b may be formed, and further, three or more regions having different restoring and contracting properties may be formed. By doing this, it is possible to knit different lace knitted fabrics, for example, a rigid lace that hardly imparts restoration shrinkage and a stretch lace that imparts restoration shrinkage, in a single knitting preparation work. It is possible to improve efficiency. This means that in the same way, it is possible to knit two or more types of lace knitted fabrics with different elasticity in a single preparatory work, providing an effective production method in the case of a large variety of small lot production. It means that it is possible to do. In other words, when knitting lace knitted fabrics of the same material but different elasticity, the lot size is too small to be knitted using the entire width of the lace knitting machine, and the winding length of one roll is shortened. Even in the case where it is necessary, it is possible to continuously knit other lots by the knitting method of the present invention, and if necessary, just replace the pattern plate to perform thread insertion work into the guide, which is troublesome. It can be omitted and contributes to the efficiency of production. It should be noted that when such plural kinds of lace knitted fabrics are continuously knitted, the tension adjusting mechanism exemplified in the above-mentioned embodiment does not necessarily have to be used.

[0010]

As described above, according to the present invention,
It is possible to sew a continuous lace knitting and decorate it, and at the same time give elasticity only to the required local parts, extend only the essential parts to restore it, and tighten the important parts as needed. We can now offer lace knitting.
