Description

  The present invention is a cylinder having a soft texture and good stretchability, which can be commercialized while cutting the end of a cylindrical circular knitted fabric containing elastic yarn into an arbitrary shape. Related to circular knitted fabric.

Conventionally, knitted fabrics and products that allow so-called free cutting are commercially available, which can be cut into circular knitted fabrics containing elastic yarns into arbitrary shapes, and can be commercialized with the cut parts cut without starting sewing. Has been.
Especially for inners such as shorts, girdles, shirts, etc., it is popular as a product with excellent aesthetics of the appearance when worn, without the sewed outer part of the skirt appearing prominently. Proposals have been made for elastic yarns and knitted fabrics that do not cause fraying or curling of the cut portion so that cutting is possible.
For example, after knitting a circular knitted fabric containing a non-heat-sealed elastic yarn, the ear portion of the tubular knitted fabric is cut and opened, and the elastic yarn is fixed by dry heat treatment around 190 ° C., Thermal fusion can be achieved by preventing fraying and curling, and heat-treating a knitted fabric knitted with a heat-fusion elastic yarn that can be heat-fused at a low melting point with dry heat at around 190 ° C or wet heat at around 120 ° C. There is known a method for preventing the occurrence of fraying and curling by heat-bonding the elastic fibers.

On the other hand, a circular knitted fabric is not opened, and it is also applied to clothing and the like in a cylindrical shape. In such a knitted fabric, a heat-sealed elastic yarn and other yarns are plated. It has been proposed that the cut portion that becomes the opening portion is not sewed and made into a garment without being cut by heat set processing (see, for example, Patent Document 1 below).
However, in a clothing product made of such a tubular knitted fabric, if the cut portion is made free-cut as described above, the stretchability and texture may be adversely affected. In order to obtain a clothing product, it is necessary to place the circular circular knitted fabric in a formwork and heat set it. Especially, the circular circular knitted fabric having a product width of about 30 to 50 cm is heated. In the case of circular knitted fabric knitted with non-heat-bonded elastic yarn during the setting process, traces of the formwork remain at the ears of the tubular knitted fabric, or the thermal effect of sufficiently fixing the elastic yarn cannot be obtained. In other words, a knitted fabric that is substantially free-cut can not be obtained even if the stretchability and texture are good.

  In addition, in a cylindrical circular knitted fabric knitted with a low-melting-point heat-sealing elastic yarn, the elastic yarn is fused by a wet heat treatment at around 120 ° C., so that there is no trace of the formwork and the elastic yarn Although a circular knitted fabric with no fraying or curling can be obtained by fusing each other, elastic yarns and non-elastic yarns such as nylon and polyester can be fused, which inhibits stretchability. It is hard to stretch and becomes a circular knitted fabric with a hard texture.

  Patent Document 2 below discloses a weft knitted fabric in which weft knitted composite yarns containing non-elastic fibers and heat-bonded polyurethane elastic fibers and heat-bonded polyurethane elastic fibers are heat-sealed. It is also disclosed that the composite yarn containing the heat fusion polyurethane elastic fiber is knitted every other course, and the non-heat fusion polyurethane elastic fiber is knitted in the other course. Compared to knitted fabrics that are woven with heat-bonded polyurethane elastic fibers and fixed in structure by heat-sealing, the fraying and curling suppression tends to be inferior. When heat setting, it is difficult to obtain the desired free cut performance.

  Further, Patent Document 3 discloses a heat-bondable polyurethane urea elastic fiber that does not have heat-fusibility but can exhibit heat-bonding by heat-set processing and can exhibit a fraying prevention effect. Compared to elastic elastic yarn, it has the characteristics that it can maintain excellent stretchability and stretch recovery even after heat set processing, but since the yarn itself is not fused, it is especially knitted combined with other fibers In the case where the tubular knitted fabric is still put in a mold and subjected to heat setting treatment, the composite condition for obtaining the desired free cut performance may be restricted.

  Thus, a cylindrical circular knitted fabric that contains elastic yarn, has good stretchability, has a soft texture, can be freely cut, and can be commercialized with the cut portion cut, and the circular knitted fabric There are currently no products of clothing or the like made of the ground, in which a cylindrical portion is formed without sewing, and at least a part of the cut end is cut.

  The problem to be solved by the present invention is that the end of a knitted fabric containing elastic yarn is cut into an arbitrary shape, and can be commercialized with the cut state, and has a soft texture and good stretchability. It is to provide a cylindrical circular knitted fabric.

In order to solve the above-mentioned problems, the present inventor has repeatedly conducted experiments such as a wear durability test on the elastic yarn and the heat treatment condition, and as a result of intensive studies, the present invention has been completed.
That is, the present invention is as follows.
[1] A cylindrical circular knitted fabric containing an elastic yarn that can be commercialized with the cut portion being cut, and at least the knitted fabric structure constituting the cut portion has a low melting point heat fusion elasticity The cylindrical circular knitted fabric, wherein the yarn and the non-heat-sealing elastic yarn are alternately knitted in a tentacle structure.

  [2] A clothing product having an unopened cylindrical portion made of the cylindrical circular knitted fabric according to [1], wherein an end of the portion is cut into an arbitrary shape, The apparel product wherein at least a portion of the cut ends remain cut.

  By using the cylindrical circular knitted fabric according to the present invention, it is possible to produce a product while cutting the end of the cylindrical circular knitted fabric, and it has a soft texture with good stretchability. It is possible to obtain a product that is excellent in washing durability and is comfortable to wear with an appropriate tightening feeling when worn.

It is the schematic which shows an example of the clothing product manufactured using the cylindrical circular knitted fabric which concerns on this invention.

Hereinafter, the present invention will be described in detail.
The cylindrical circular knitted fabric according to the present invention is a knitted fabric that can be commercialized as it is after it is knitted and dyed without cutting off the ears of the cylindrical circular knitted fabric. Say. Furthermore, the cylindrical circular knitted fabric according to the present invention is obtained by cutting the cylindrical circular knitted fabric with a necessary length such as tops or bottoms of clothing, and either the upper end or the lower end of the cylindrical circular knitted fabric. Alternatively, it is a cylindrical circular knitting that is commercialized with the cut portions at both ends cut into a desired shape.

  The cylindrical circular knitted fabric according to the present invention is characterized in that it contains an elastic yarn, but the elastic yarn needs to be knitted in all courses in the vicinity of the cutting portion where the elastic yarn is cut in an arbitrary shape. The elastic yarn does not necessarily need to be knitted in all courses except in the vicinity of the portion, and there may be a course in which the elastic yarn is not knitted every one to several courses. However, the elastic yarn is preferably knitted on all courses or knitted on a course-by-course basis because of stretchability and fit.

The knitted fabric structure of the cylindrical circular knitted fabric according to the present invention, which constitutes a cutting portion that contains elastic yarn and is cut in an arbitrary shape, is a tentacle structure.
A structure other than the tengu, for example, a change structure such as a knitting knitting using a tuck structure, is not suitable because the texture becomes hard and the stretchability is lowered. In addition, the knitting structure other than the cutting part to be cut in an arbitrary shape does not necessarily need to be a tengu, the use of a tack structure or the use of a welt structure, and the combined use of these two structures are possible. It is possible to produce a knitted fabric with any elasticity and fit.

In the present invention, the elastic yarn contained in the cutting portion that is cut into an arbitrary shape is a combination of a heat-fusion elastic yarn and a non-heat-melting elastic yarn.
The heat fusing elastic yarn is the state of the cylindrical circular knitted fabric of the present application, and is melted by heat treatment for 1 minute at a dry heat of 150 ° C. or higher and 220 ° C. or heat treatment for 30 seconds at a wet heat of 100 ° C. or higher and 130 ° C. or lower. An elastic yarn in which the elastic yarns are fused to each other. For example, as shown in Patent Document 2, a polyol, diisocyanate, and a low molecular weight diol are reacted with a both-end isocyanate group prepolymer obtained by reacting polyol and diisocyanate. And an elastic yarn obtained by melt-spinning a polymer obtained from the hydroxyl group prepolymers obtained at both ends.

  The non-heat-bonded elastic yarn is an elastic yarn in which the elastic yarns are not fused with each other under the heat treatment conditions in which the above-mentioned heat-fused elastic yarn is melted. As the elastic yarn, dry spinning or melt spinning can be used, and the polymer and the spinning method are not particularly limited. It is preferable that the elastic yarn has a breaking elongation of about 400% to 1000%, is excellent in stretchability, and does not impair the stretchability around a normal processing temperature of 180 ° C. in the presetting process during dyeing. Further, as the non-heat-bonded elastic yarn, an elastic yarn imparted with functions such as high setting property, antibacterial property, moisture absorption and water absorption by adding a special polymer or powder can be used.

  As the non-heat-bonding elastic yarn, a polyurethane elastic yarn that does not melt under the above-described heat treatment conditions but can exhibit fraying prevention performance by heat fixation can be used. Specifically, for example, the compression deformation start temperature by thermomechanical analysis (TMA) described in Patent Document 3 is 150 ° C. or higher and 180 ° C. or lower, and the thermal cutting time at 180 ° C. and 150% elongation is 30 seconds. Examples thereof include polyurethane elastic yarns. If the yarn has such a performance, it does not melt under the above-mentioned heat treatment conditions, but has a heat fixing performance, so that it is effective in preventing fraying of the cut portion, and also suppresses the stretchability and texture reduction of the fixing portion. Is preferable.

  Examples of such heat-adhesive elastic yarns include polyurethane urea elastic fibers containing 5 to 40% by weight of a polyurethane compound, and in particular, by using a crosslinked polyurethane having a hardness of 80 A or less as the polyurethane compound, It can be suitably obtained. In addition, it is preferable that the polyurethane urea is obtained from a copolymerized polyalkylene ether diol composed of different alkylene ethers having 2 to 10 carbon atoms.

  The fineness of these heat-sealing elastic yarns and non-heat-sealing elastic yarns can be about 10 to 160 dt (decitex, hereinafter using the same symbols), and in particular, elastic fibers of about 40 to 120 dt. Is preferred.

  In the present invention, the inelastic yarn refers to polyester fibers such as polyester and polytrimethylene terephthalate, and synthetic fibers such as polyamide fibers, and these bright yarns, semi-dal yarns, full dull yarns, etc. may be used arbitrarily. It is possible to use a fiber having an arbitrary cross-sectional shape such as a round shape, an elliptical shape, a W-shape, a saddle shape, and a hollow fiber, and the shape of the fiber is not particularly limited. A crimped yarn such as false twist can be used, and the use of a crimped yarn is particularly preferable. Furthermore, the thickness of the synthetic fiber can be about 20 to 160 dt, and it is preferable to use a synthetic fiber of about 30 to 110 dt in view of the bursting strength and thickness of the knitted fabric.

In the present invention, by effectively combining the above-mentioned heat-sealing elastic yarn and non-heat-sealing elastic yarn, there is no occurrence of fraying or curling of the cut surface, and excellent elasticity and soft texture. You can get the ground.
That is, in a tentacle structure, by thermally knitting one heat fusion elastic yarn and one non-heat fusion elastic yarn so that the heat fusion elastic yarns are not fused to each other, a heat fusion elastic yarn is obtained. It is possible to remarkably reduce texture hardening and stretch failure, which are disadvantages when forming a knitted fabric alone, and there is no occurrence of fraying or curling of the cut portion, which is a problem of the present invention, and stretchability Excellent and soft texture can be produced.

At this time, the fineness ratio of the heat fusion elastic yarn and the non-heat fusion elastic yarn is preferably 0.5 to 1.5, more preferably 0.6 from the viewpoint of texture and stretchability. ~ 1.4.
The fineness ratio is given by the following formula:
Fineness ratio = fineness of non-heat-bonded elastic yarn (dt) / fineness of heat-bonded elastic yarn (dt)
Ask for.

  The method for knitting the elastic yarn is not particularly limited, but it is preferable that the elastic yarn is knitted in combination with the non-elastic yarn. There is no particular limitation on the combination method of the elastic yarn and the inelastic yarn. The method of knitting by plating that knitted the inelastic yarn and the elastic yarn at the same time, the method of knitting the coated elastic yarn in which the elastic yarn is coated with the inelastic yarn Any method such as a method of knitting a coated elastic yarn to a non-elastic yarn by plating can be used. From the viewpoint of feeling, it is preferable that the inelastic yarn and the elastic yarn are knitted simultaneously by plating, and the elastic yarn is preferably a covered elastic yarn covered with the inelastic yarn. A method for coating the elastic yarn with the non-elastic yarn is not particularly limited, and the coated elastic yarn can be manufactured by a covering method, a twisting yarn method, an air entanglement method, or the like.

  It should be noted that, in the coated elastic yarn, one coated elastic yarn in which the heat-sealed elastic yarn is completely covered with the non-elastic yarn and one coated elastic yarn in which the non-heat-bonded elastic yarn is completely covered with the non-elastic yarn are alternately arranged. In the case of knitting, there is a concern that the cut portion may be frayed because there is no portion where the elastic yarns are in contact with each other even if the heat fusion elastic yarn is fused by heat treatment after knitting of the knitted fabric. Therefore, it is preferable that the elastic yarn is exposed from the gap between the non-elastic yarns after the knitting of the knitted fabric. For example, when the coated elastic yarn is manufactured, the fineness of the non-elastic yarn is 33 dt or less. Further, the exposed state of the elastic yarn can be appropriately adjusted by setting conditions such as setting the number of twisted yarns to 600 times / m or less. The exposed heat-bonded elastic yarn and non-heat-bonded elastic yarn are in contact with each other, and the heat-bonded elastic yarn and non-heat-bonded elastic yarn are bonded by heat treatment after knitting of the machine, thereby preventing fraying and curling. It becomes possible to prevent.

  The cylindrical circular knitted fabric according to the present invention can be commercialized into a clothing product with the cut portion being cut. The cutting part can be of any shape, for example, in the case of running tops, the lower end corresponding to the bottom of the cylindrical circular knitted fabric is cut almost linearly, and the neckline at the upper end and the armhole are along the shape. There are a case where the product is manufactured with cutting, a method in which only the bottom hem is cut and the upper end of the neck and the armhole are folded back and the piping is finished with a separate cloth. Of course, the cutting shape of the skirt portion is not limited to a substantially linear shape, but can be an arbitrary shape such as a wave shape or a jagged shape. In addition, it is preferable to cut the cylindrical circular knitted fabric into an arbitrary shape after performing dyeing and finishing set because dimensional change due to dyeing or finishing set does not occur.

  The knitting machine for producing the cylindrical circular knitted fabric according to the present invention is a circular knitting machine having a knitting machine having a hook diameter of about 10 to 20 inches, and the knitting yarn can be arbitrarily switched at the same yarn feeder. It is preferable to use a card circular knitting machine, and the knitting machine hook diameter is selected according to the product width. About the gauge of a knitting machine, since it becomes possible to cut | judge in arbitrary shapes and it can be set as a product as it is, use of a fine gauge knitting machine is suitable and use of about 26-40 gauge knitting machine is preferable. In particular, the use of a 28-36 gauge knitting machine is preferable because it can be cut into an arbitrary shape to obtain a product as it is and a product having good stretchability can be obtained. The knitted fabric density is also arbitrary, but it is preferable to set the density as dense as possible so that the knitted fabric is not unraveled in a portion cut into an arbitrary shape and becomes a soft product.

  As a method for dyeing and finishing a cylindrical circular knitted fabric according to the present invention, a normal dyeing and finishing process can be used. In this step, dyeing conditions according to the fiber material to be used can be used, and the dyeing machine to be used can be arbitrary, such as a liquid dyeing machine, a wins dyeing machine, and a paddle dyeing machine. When performing so-called piece dyeing, in which the ground is cut approximately one by one into the product length and dyed, it is preferable to use a paddle dyeing machine, and when dyeing a tubular knitted fabric with a long length, It may be dyed by a flow dyeing machine or a wins dyeing machine. You may perform the process which improves water absorption and a softness | flexibility.

  In addition, in the production of the cylindrical circular knitted fabric according to the present invention, the heat-sealing elastic yarn is fused in the dyeing process described below, so that the heating process is 150 ° C. or higher for dry heat and 100 ° C. or higher for wet heat. is required. Therefore, it is preferable to use a dry heat setting machine such as a pin tenter that can be heat-treated in a cylindrical shape, or a wet heat (steam) setting machine such as an autoclave. The heating condition may be any condition as long as the heat-bonding elastic yarn is melted. If dry heat is applied, heat treatment is preferably performed at 150 ° C. or higher and 220 ° C. or lower for 10 to 180 seconds, and more preferably 180 ° C. or higher and 195 ° C. or lower. . Moreover, if it is wet heat, the heat processing for 2 to 120 second at 100 degreeC or more and 130 degrees C or less is preferable, More preferably, it is 110 degreeC or more and 130 degrees C or less for 30 to 60 seconds.

  As an example of the dyeing process, pipes and sleeves are wrapped with tape and wrapped, and when manufacturing a sleeveless fit inner with the skirt cut into an arbitrary shape, a cylindrical circular knitted fabric is knitted, After cutting with a length of one product, it is put into a paddle dyeing machine, scoured and dyed, dried, and then set in a cylindrical knitted fabric in a body-shaped formwork. Steam setting is performed at a degree, and then the hem is cut into an arbitrary shape, and the collar and sleeves are sewn with tape to produce a product. In addition to the method in which the raw fabric of the tubular knitted fabric is directly put into the dyeing machine and scouring and dyeing, steam setting is performed in a vacuum state of about 100 ° C. before feeding into the dyeing machine, and the heat-bonded elastic yarn is heated beforehand It can also be fused.
