Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for treating an edge portion on the knitting start side when obtaining a cylindrical stockinette fabric using a horizontal stockinette knitting machine.

In the case of a horizontal stockinette knitting machine with a sinker, it is possible to knit a cylindrical fabric with an open end at any time, but in the case of a horizontal stockinette knitting machine without a sinker, it is possible to knit a cylindrical fabric with an open end. It is not possible for people of Japanese descent to suddenly create a tubular knitted fabric.

This invention provides a stockinette knitting machine that does not have a sinker, but has a cylindrical stockinette fabric with an open knitting start side, and the edge of the knitted fabric on the knitting start side is treated to prevent it from unraveling. The purpose of this paper is to provide a method by which a knitted fabric can be knitted in a tubular shape using arbitrary knitting yarn a using a horizontal stockinette knitting machine. Alternatively, an arbitrary circular course is knitted with water-soluble vinylon yarn c, and the stitches of several circular courses following this course are knitted with a small amount of heat-adhesive yarn A and a small amount of heat that is stretchable at room temperature. A yarn in which a shrinkable yarn B is mixed with a yarn C other than the above, which is twisted so that the yarn B is covered with the yarn C and further covered with the yarn A. A certain darning yarn b is used, this darning yarn b is knitted in a stretched state, and the subsequent round course is bag-knitted with the arbitrary knitting yarn a to obtain a bag-knitted fabric whose tip is once closed. After that, the stitches knitted with the water-soluble vinylon yarn c are dissolved in water to open the tips of the bag knitted fabric, and the stitches knitted with the overdarning yarn b are coated with the thermoadhesive yarn. By applying heat in a range where the heat-shrinkable yarn B melts while the string A melts, the heat-shrinkable yarn B shrinks the overdarning yarn b, thereby shrinking the stitches in the area. , partially adhering the overdarning yarn b forming the stitches with the melted thermofusible yarn A, so that the stitches on the knitting start side of the knitted fabric made of the knitting yarn a do not unravel; A method for treating a knitting start side edge of a cylindrical stockinette knitted fabric, characterized by:

An example is a knitted glove as shown in FIG. 10,
That is, the present invention will be described in detail by taking as an example a glove having finger stalls whose tips are open so that each finger can be exposed from the tips of the finger stalls 1, 2, 3, 4, and 5. Such a knitted glove 10 is made by knitting a little finger bag, a ring finger bag, a middle finger bag, and a third finger bag using a known knitting machine.
When knitting the index finger pouch 4 and toga finger pouch 5 from the tip side of each finger pouch, each finger pouch 1 to 5 is knitted short, and each finger pouch 1 to 5 is knitted according to the method of the present invention. When processed, the mouth edges 1a, 2a, 3a, 4 of each short cylindrical finger pouch 1 to 5 are formed.
It is possible to easily obtain a glove as shown in FIG. 1 in which a and 5a are treated so that they do not unravel from the knitting start side.

In addition, in the figure, 6 is a four-piece body knitted following four finger bags 1 to 4, 7 is a five-piece body knitted following four finger bags 6 and toga finger bags 5, and 8 is a wrist portion. That is, in the method of the present invention, each of the finger bags 1 to 5 of the stockinette glove 10 is knitted into a bag shape with the tips of the finger bags closed by a known stockinette glove knitting machine as described above. Finger bags 1 to 5 are knitted as follows.

One embodiment will be explained by taking the little finger pouch 1 as an example. As shown in FIG. After knitting with vinylon yarn c, several circular courses 121 following the course 11
, 122, etc. are replaced with water-soluble vinylon yarn c, and knitted as follows using darning yarn b having the following configuration.

That is, a small amount of heat-adhesive yarn A, a small amount of heat-shrinkable yarn B that is stretchable at room temperature, and a large amount of yarn C other than the above.
In the natural state at room temperature, the yarn C covers the yarn B in a large meandering state, as shown in FIG. The yarns A are twisted together in a lightly purled state. Overlock yarn b is used and knitted in a stretched state as shown in FIG. In addition, as an example of a heat-shrinkable yarn suitable for constituting such a darning yarn b, for example, heat-shrinkable yarn "Mobilon Core Double Yarn" (trade name) manufactured by Nisshinbo Co., Ltd. may be mentioned. As an example of the heat-adhesive yarn, for example, the heat-adhesive fiber "Toray Elter Yarn" (trade name) manufactured by Toray Industries, Inc. can be mentioned, and both of the above-mentioned yarns are used as the yarn A-B. In this case, "Mobilon Core Double Yarn" will not melt even when heated to 130'C, but it will shrink sufficiently, and "Toray Ergoo Yarn" will melt even at 130'C and have sufficient thermal adhesive properties. able to demonstrate.

Examples of yarns C other than those mentioned above include acrylic yarns, cotton yarns, cotton yarns, uri-nylon yarns, etc. However, yarns A and B are more expensive than yarns C. Therefore, in this embodiment, in order to achieve the intended purpose at the lowest possible cost, the ratio of each yarn (A:B:C) in the overdarning yarn b is as follows:
The weight ratio was approximately (1:1:8). The darning yarn b shown in FIG. 3 is made by spinning the yarns B and C in the above ratio in the S direction by approximately 1.5 mm in the first step. P soil yarn is twisted, and in the second step, it and yarn A having the above ratio are twisted in the Z direction by about 1 CrI'. P
．． I. Darning yarn b, which is made by twisting yarns and is composed of yarns A, B, and C in the above-mentioned ratio, is twisted because yarn B is stretched in the first step due to the nature of the yarn. In the second step, the yarn A is further covered with the yarn A as shown in FIG. 3 in the second step. In this embodiment, the darning thread b (FIG. 3) constructed as described above is used.
is expanded to about twice its size (Fig. 4), and the above-mentioned several lap courses 121, 122, 123, 12 are organized,
In the last round course 124, the knitting yarn a constituting the other parts of the glove 10 is doubled, and thereafter the little finger bag 1 is knitted in arbitrary courses 131, 132, . . . using this knitting yarn a.

In addition, the circular knitting course 121 using the overdarning yarn b,
In 122..., the stitches are made smaller than the stitches in the subsequent knitting courses 131, 132, etc. of the 1 part of the little finger bag using the knitting yarn a, and the circular knitting courses 121, 122...
12. was organized. For example, knitting course 13 using knitting yarn a
If the degree of 1,132. Little finger bag 1
After knitting the finger bags 2 to 5 and knitting the glove 10 in the same manner as above, when the glove 10 is removed from the glove knitting machine,
The knitting structure at the tip of each finger pouch 1 to 5 is a pouch knitting structure in which the tip is closed like the little finger pouch 1 shown in FIG. 2, and the stitch size of knitting courses 121, 122, etc. Although the size is not faithfully expressed in Fig. 2, by restoring the darning yarn b to its natural state (Fig. 3) and reducing its density, the knitting yarn a Course 131,1 organized by
The size of the stitches had been reduced to a fraction of the size of the 32... stitches.

In the method of the present invention, among the knitted fabric of the glove 10 knitted as described above, the stitches knitted with the water-soluble vinylon yarn c, that is, in the case of this embodiment, the knitting course 11
The stitches are dissolved and erased with water, and the tip of the finger sack 1 is made into an open shape.

In addition, in the method of the present invention, the heat-adhesive yarn A constituting the darning yarn b is melted in the stitches knitted with the darning yarn b; The heat-shrinkable yarn B constituting the overdarning yarn B is shrunk by applying dry heat or wet heat (for example, 130° C.) in a range where it only shrinks without melting, and is thermally bonded. sexual thread A
When the darning yarn b is melted, the knitted fabric at the opening edge 1af) of the little finger pouch 1 knitted with the darning yarn b, that is, the knitted fabric at the edge on the knitting start side of the knitted fabric that is not dissolved by water, becomes the knitted fabric of the darning yarn b. The length of the overcoat yarn B shrinks by approximately 30% due to heat contraction, causing the stitches to become clogged.Also, even if the heat-shrinkable yarn B contracts, the yarn C, which accounts for most of it, is Since it does not shrink, the yarn C is in a more meandering state as shown in FIG.

Therefore, the stitches of the first course 121 of the mouth edge 1a of the little finger bag 1 knitted with the darning thread b are
Not only is it in a state where it cannot be unraveled easily because of its poor slippage, but at the same time, the knitted fabric of the open edge 1a of the little finger pouch 1 that is in such a state is made of darning thread. Since the intersection of the sinker loop and the needle loop of the stitch consisting of stitch b, that is, the stitch consisting of yarn B and C that do not melt in water or heat, is adhesively connected at random by the melted heat-adhesive yarn A. The above state, that is, the edge portion of the knitted fabric is more reliably maintained in a state where it does not unravel. In this way, the darning thread b made according to the method of this invention
The knitted fabric of the opening edge that can be knitted by knitting is obtained by knitting the overdarning yarn B as described above and then heat-setting it as described above. As a result of this action, the reduced shape of the overdarning yarn b and the stitches are set even with the adhesive properties of the heat-adhesive yarn A, but the comparatively expensive overdarning yarn b The mixing ratio of yarn A is sufficient as long as the stitches made of overlock yarn B do not lose the elasticity inherent in the knitted fabric, and each stitch of the heat-adhesive yarn A is properly bonded. Therefore, the smaller the size is, the more preferable it is within the range that can achieve this purpose, and as mentioned above, the method of the present invention spans two steps of forming heat-shrinkable yarn B that is stretchable at room temperature. In addition to shrinking the stitches by the contraction action, the contraction of the yarn B causes the other non-heat-shrinkable yarn C twisted with it to become meandering, so that the stitches are loosened. Therefore, it is preferable that the proportion of the relatively expensive heat-shrinkable yarn B in the darning thread b is as small as possible within the range that can achieve the above purpose. thread b
It will be easily understood that it is preferable that the proportion of the non-heat-shrinkable and other yarns C in the fibers is, on the contrary, larger.

For this reason, in the above example, the ratio of each yarn (A:B:C) is approximately (1:1:
Although good results were obtained in Example 8), the mixing ratio of the yarns A, B, and C in the method of the present invention is not necessarily limited to the ratio in the above example. Note that the knitting courses and the number of courses using the water-soluble vinylon yarn c according to the method of the present invention are not limited to the above embodiments, and in other embodiments, the knitting courses and the number of courses may be 1 arbitrary lap course of the bag knitted fabric with the part closed
Overcoat yarn (b) knitted with water-soluble vinylon yarn c (more than one course), with stitches of several circular courses following the course (b)
It may be organized in

Further, the number of courses of knitting using the darning yarn b according to the method of the present invention is not limited to the number of courses in the above embodiments.

Furthermore, in the above examples, the method of the present invention is
Although we have described an example of a method for treating the edge of the knitting start side of an open finger bag of a glove, in other embodiments, this method can be applied to a tube with an open end as shown in FIG. A method for treating the end edge 21a of the toe bag 21 on the knitting start side when knitting a toe cover 22 or undersocks or socks having a toe bag 21 with a flat knitting machine without a sinker. Or, when the supporter 23 shown in FIG.
When the processing method of 3a is applied, the knitting course or any circular course is knitted with water-soluble vinylon yarn c, and then the end edge of the bag knitted fabric on the knitting start side is melted. A toe cover 2 that can be opened and that the knitting yarn does not unravel from the edge on the knitting start side created in this way.
2, undersocks, socks, supports 23, etc., can be easily obtained.

The present invention has been described above with reference to embodiments, but in any case, the method for treating the edge of the knitting start side of a cylindrical stockinette knitted fabric according to the method of the present invention is the method described above. That is, when knitting a cylindrical knitted fabric using any flat knitting machine, the starting course or any round course is knitted with water-soluble vinylon yarn c, and the stitches of several round courses following this course are knitted with water-soluble vinylon yarn c. , a small amount of heat-adhesive yarn A, a small amount of heat-shrinkable yarn B that is stretchable at room temperature, and a yarn C other than the above.
The darning yarn b is made of a yarn that is mixed with the darning yarn b, and the darning yarn b is twisted so that the yarn B is covered with the yarn C and further covered with the yarn A. The knitted fabric is knitted with the darning yarn b in a stretched state, and the subsequent round course is bag-knitted with the arbitrary knitting yarn a. Dissolve the stitches knitted with yarn c in water 7
Therefore, the knitted fabric immediately obtained by the above-mentioned knitting process is a knitted fabric made of water-soluble vinylon yarn c, whether the leading edge is closed or not. The bag knitted fabric made of the knitting yarn a whose knitting start part is made to disappear becomes a knitted fabric of several courses made of the overdarning yarn b, and becomes a cylindrical knitted fabric with an open tip.

Therefore, according to the method of the present invention, a cylindrical knitted fabric with an open end can be substantially knitted even with a flat knitting machine without a sinker, and it is possible to knit a cylindrical knitted fabric with an open end, such as a supporter. A large number of tubular knitted fabrics of appropriate length can be continuously knitted and easily separated. In addition, in a knitted fabric in which several courses of the knitted fabric made of the darning yarn b are used as the knitting start side edge of the open cylindrical fabric, the stitches made of the darning yarn b are the same as the yarn B. Due to the action, the stitches are already smaller than the stitches made of other knitting yarns a before heating processing, but in the method of this invention, the stitches knitted with the darning yarn b are By applying heat in a range that melts the heat-adhesive thread A, but does not melt the heat-shrinkable thread B, the heat-shrinkable thread B is heat-shrinked, and the whole Since this is a method of further shrinking the darning yarn b, the stitches of the knitted fabric made of the darning yarn b are further reduced in size by this heating process. In this way, in the method of the present invention, the stitches knitted with the darning yarn b as described above are reduced in two stages, but the darning yarn b is heat-shrinkable as described above. Since the non-heat-shrinkable yarn C is force-pulled in a spiral manner around the non-heat-shrinkable yarn B, the stitches made of this darning yarn B are the same as the darning yarn B.
The smaller the yarn C becomes, the more the yarn C becomes meandering, making it difficult for the stitches to unravel. Moreover, according to the method of the present invention, in such a condition, the sinker of the stitch made of the overdarning yarn b Since the intersection of the loop and the needle loop is partially bonded to each other by the molten heat-adhesive yarn A, the edge of the knitted fabric made of the darning yarn B is very soft as a whole. It has become difficult to unravel.
