Description

Detailed Description of the Invention (Field of Industrial Application) The present invention is directed to a composite fabric using different types of fibers, particularly a composite fabric using a mixture of raw silk and different types of fibers, in which shrinkage wrinkles caused by different types of fibers do not occur. and its manufacturing method.

(Prior art) Composite fabrics using two or more different types of fibers, such as natural fiber yarn and chemical fiber yarn, are well known, needless to mention, and various types of composite fabrics are on the market. This is known. Among composite fabrics made of raw silk and other fibers, which are the subject of the present invention, various mixed fiber products already exist.

(Problems to be solved by the invention) In the above-mentioned composite fiber composition using raw silk and other fibers,
Due to the heat history during smelting, dyeing, finishing processes, etc., shrinkage wrinkles are likely to occur due to the difference in thermal shrinkage between raw silk and other fibers.
Measures to improve this problem have been sought for a long time, but there are currently no effective measures.

(Means for Solving the Problems) The present invention effectively prevents the generation of shrinkage wrinkles caused by the difference in heat shrinkage in a composite fabric made of raw silk and different types of fibers by performing a specific treatment on different types of fibers. ,
It is possible to provide a composite fabric that does not cause shrinkage wrinkles, and specifically, as a composite fabric, the raw silk used for the warp or weft has a shrinkage value that is approximately the same as the raw silk used for the warp. and is woven using other fibers used as warp threads, or other fibers used as warp threads, weft threads, or both warp threads and warp threads that have approximately the same shrinkage value as the raw silk used for the weft threads and that are used as weft threads. Furthermore, when manufacturing a composite fabric made of raw silk and other fibers, the shrinkage of the other fibers used for the warp is set at a high temperature, so that the shrinkage is approximately the same as that of the raw silk used for the warp. Or, by subjecting the shrinkage of other fibers used for the weft to the same value (approximately the same value as the shrinkage of the raw silk used for the weft), then the raw silk and the other fibers are The purpose is to weave using the warp or weft, or both the warp and warp, and then subject it to high-temperature setting.

(Function) According to the above-mentioned technical means of the present invention, as a composite fabric made of raw silk and different types of fibers, yarns made of different types of fibers used for the warp or weft, or for both the warp and the weft, can also be used for the warp or weft, or for the warp. By using a material that has been treated to have approximately the same shrinkage as the raw silk used for both wefts, there is no difference in heat shrinkage throughout the resulting composite fabric, and this makes it possible to differentiate between conventional raw silk and different fibers. It is possible to effectively suppress shrinkage wrinkles caused by the difference in thermal shrinkage that is observed in composite fabrics. At this time, the treatment to make the shrinkage of the yarn made of different types of fibers approximately the same as the shrinkage of raw silk can reliably and easily achieve the desired purpose by setting at a high temperature, resulting in a beautiful finished appearance with no shrinkage wrinkles. This makes it possible to provide a composite fabric with a wide range of properties.

(Example) A suitable example of the fabric and the manufacturing method thereof according to the present invention is as follows.
The explanation will be given below in sequence with reference to FIGS. 1 to 8.

The raw silk used in the present invention may be a refined pre-kneaded thread, an unrefined thread, or an unkneaded thread in between, and although there is no particular restriction, it usually has a 2
It is preferable to use a pre-kneaded yarn whose weight has been reduced by about 5%.

At this time, each of these raw silks may be either yarn-dyed or undyed, and then other fibers used in the present invention (
Examples of "different types of fibers" include synthetic fibers made of polyester, polyamide, polyacrylonitrile, etc., synthetic fibers made of acetate, etc., and natural fibers such as cotton and hemp, but are not particularly limited. Polyester threads made of polyethylene terephthalate, cationically dyeable polyester, etc. are preferably used. These other fibers (different types of fibers) are preferably yarn-dyed yarns, but may also be undyed yarns, and may also be any other fibers such as spun yarns and filament yarns, and there are no particular limitations on these points.

In the present invention, "other fibers having approximately the same shrinkage value as raw silk", which was previously stated as part of its constituent requirements,
Or, regarding the expression "to make the shrinkage of other fibers approximately the same as the shrinkage of raw silk", it means "to make the shrinkage of other fibers approximately the same as the shrinkage of raw silk in the process after weaving". This means "setting the shrinkage rate in the process." That is, for example, in the case of pre-kneaded raw silk, the shrinkage rate in the process after weaving is approximately the same as the shrinkage rate in the process after weaving in the case of unrefined raw silk. It is necessary to set the shrinkage rate in the process after weaving, and in this case, the value is usually different for pre-kneaded yarn and unrefined yarn.In addition, due to the properties of raw silk, twist, and other factors, Since the shrinkage rate in the process after weaving may differ, please understand the shrinkage rate in the process after weaving of the raw silk to be used beforehand (it is acceptable even if the shrinkage rate is zero at this point). It is necessary to set this value so that the shrinkage rate of other fibers in the post-weaving process is approximately the same value.In this way, the shrinkage of other fibers is approximately the same as the shrinkage of raw silk. In general, high-temperature setting is an example of a desirable method for achieving a good temperature.The conditions for high-temperature setting vary depending on the type of yarn, etc., but it is usually about 60 to 150 degrees Celsius, preferably about 90 to 130 degrees Celsius, and the effect is achieved. It is desirable to carry out the heat setting by appropriately determining the time within which this occurs.In addition, in the case of dry heat setting, it is desirable that the temperature range be 20 to 30°C higher than the temperature range normally used in the above-mentioned heat setting. However, it goes without saying that there are no particular restrictions on the setting temperature and time as exemplified above.Furthermore, other fibers can also be yarn-dyed, but as is known, when yarn-dying, the above-mentioned high-temperature, moist heat Since setting may be applied at the same time, in such cases it is possible to omit the high-temperature setting mentioned above.In addition, for boat fishing, dyeing should be carried out within the range of about 60 to 150 degrees Celsius. often.

In the present invention, the raw silk and other fibers may be used as separate threads, and for example, as illustrated in FIG. There is no problem in using it as a clue for alignment, and there are no particular restrictions.

In the present invention, although not particularly limited,
It is desirable that the raw silk and other fibers described above be wound around, for example, a frame or a large bobbin. Using such a frame or large bobbin is preferable because the number of changes is small and tension unevenness is less likely to occur.When winding on such a frame or large bobbin, the thread tension should be about 5 to 30 g, for example. is preferred, but there is no particular restriction. Thereafter, such raw silk or yarn fibers are warped in a warping machine as is usual practice, for example, if they are to be used as warp yarns, and are placed in a winding tube so that they can be inserted into a shuttle if they are to be used, for example, as weft yarns. It is preferable to rewind it, but there are no particular restrictions on this either.

In manufacturing the composite fabric according to the present invention, raw silk 1 and synthetic yarns 2 made of other fibers, for example, are alternately arranged in plurality as shown in FIG. 1 and used as warp yarns, or as shown in FIG. As shown in Figures 3 and 4, raw silk 1 and synthetic fiber 2 are alternately arranged and used as warp threads, or as shown in Figures 3 and 4.
To be used as warp threads arranged as shown in the figure,
The number and arrangement of the raw silk 1 and the synthetic yarn 2, which is another fiber, can be freely configured, and there are no particular restrictions. Although not shown, raw silk 1 and synthetic yarn 2, which is another fiber, can be used for both warp and weft, and in the present invention, it is possible to use any of the warp and weft. Regardless of the method used, all are included in the present invention.

In the examples shown in FIG. 1.3, normal raw silk 3 is used as the weft, and in the example shown in FIG. 5, normal raw silk 4 is used as the warp. Further, in the present invention, in addition to using the raw silk 1 and other fibers as separate threads as described above, as illustrated in FIG. It goes without saying that these can also be used as intertwisted yarns A or as a starting point for pulling yarns, so that they can be arranged, for example, as shown by the same symbols A and I in FIGS. 3 and 4.

In the present invention, when raw silk and other fibers are used as warp threads, the shrinkage of the other fibers used as warp threads may be approximately the same as the shrinkage of raw silk also used as warp threads, as described above. For example, the shrinkage of raw silk or other fibers used as the weft is irrelevant, and when the raw silk according to the present invention and other fibers are used as the weft, the shrinkage of the other fibers used as the weft is It is sufficient that the shrinkage is approximately the same as that of the warp, and the shrinkage of raw silk or other fibers used as warp threads is irrelevant in this case. In addition, when the raw silk according to the present invention and other fibers are used for both the warp and weft, the yarns used for the warp and weft described above may be used as the warp and weft, respectively, and the shrinkage of the other fibers can be adjusted to reduce the shrinkage of the raw silk. It may be approximately the same as the shrinkage. Therefore, in the composite fabric according to the present invention, other fibers (different types of fibers) whose shrinkage is approximately the same as that of raw silk are used.
In a woven fabric using the above-mentioned weft and warp as the warp, the weft of the same woven fabric is appropriate, and in a woven fabric using the other fibers (different types of fibers) as the weft, the warp of the same woven fabric is appropriate, and the weft and warp as described above It is also possible to use other fibers that do not have approximately the same shrinkage value as raw silk. On the other hand, in a fabric in which the other fibers (different types of fibers) are used in both the warp and weft, it is impossible to weave in other fibers that do not have a shrinkage value approximately equal to that of the raw silk.

In addition, in the degree of shrinkage, the warp and weft do not necessarily have to have the same shrinkage, and the degree of shrinkage of other fibers used for the warp and weft is set according to the degree of shrinkage of the raw silk used for the warp and weft. do it.

The composite fabric woven as described above is subjected to refining, etc., if necessary, and then subjected to high-temperature setting in the form of cloth. This high temperature setting is about 90-150℃, preferably 1
The treatment is carried out at a temperature of 00 to 130° C., for example, by heating for an appropriate time, but the range of these temperatures and times is not particularly limited. The above-described heating set can be carried out by wrapping the composite fabric 6 according to the present invention, as shown in FIG. 8, around a perforated pipe 5 having a large number of through holes 5a, as shown in FIG. 7, for example. However, this is not particularly limited, and it goes without saying that setting by dry heat can be similarly done by appropriately changing the conditions. In addition, this high temperature set can be used with a tenter etc.
It is also possible to do 4. For example, when textiles are subjected to printing or dyeing, high-temperature setting may be performed by passing them through a steaming or hot water process, and it goes without saying that the refining may also be performed as high-temperature setting.

The above has been a general description of the composite fabric of the present invention and preferred embodiments for obtaining the same, and the present invention is not limited in the slightest by the above-mentioned embodiments, and as long as it does not contradict the gist of the present invention. , it goes without saying that all kinds of embodiments are possible.

Next, 1.2 of specific embodiments of the present invention will be explained below.

(Example 1) Two pieces of raw silk 131, which had been reduced in weight by 20 to 25%, pre-kneaded, and had about 5% of Funoori attached, were heated at 130°C for 30 minutes.
One 275DX filament yarn of polyethylene terephthalate, which was dyed at high temperature and also served as high temperature setting, was wound onto a large bobbin, each having a yarn length of 25 g. Next, nine pieces of raw silk 1 and nine pieces of polyester thread 2 were alternately arranged as shown in FIG. 3, and warped by a warping machine to form warp yarns. At this time, the raw silk 1 has shrunk by about 2.5 to 3% compared to the original thread, whereas the polyester thread 2 that has been set at high temperature has shrunk by about 8% compared to the original thread. Because of such high-temperature setting, the shrinkage rates of raw silk 1 and polyester yarn 2 during the process after weaving were approximately the same. On the other hand, a composite fabric consisting of 1 raw silk and 2 polyester yarns was woven by using 4 out of 31 premixed and dyed raw silks as the wefts. After that, the same fabric is made into a cloth again and subjected to necessary finishing processes such as refining, and then wrapped around the perforated vibrator 5 illustrated in FIG. Such a composite fabric was obtained. After that, when normal printing and steam processing were performed, it was confirmed that no shrinkage wrinkles were caused due to the use of different types of fibers.

(Example 2) 4 pieces of raw silk 131 medium which had been reduced in weight by 20 to 25%, pre-kneaded, and had about 5% starch attached were prepared at 130°C.
For 30 minutes, undyed polyethylene terephthalate filament threads 275D x 3 that had been set at high temperature were used as weft threads, and ordinary 31 medium x 2 unrefined raw silk was prepared as warp threads. This first kneaded raw silk 1 is about 5% compared to the raw silk.
Shrinked and high temperature set polyester yarn 2
was shrunk by about 7% compared to the original yarn, and due to such high-temperature setting, the shrinkage rates of raw silk 1 and polyester yarn 2 during the subsequent weaving process were approximately the same. A composite fabric is woven using the warp and weft yarns prepared in this way by a conventional method, and then subjected to necessary finishing processes such as scouring, and then woven into a composite fabric using a tenter.
By drying at 0° C. and setting at a high temperature for 2 minutes, 1) a composite fabric according to the present invention was obtained. The white woven fabric obtained in this way is further subjected to necessary processing such as dyeing, and the resulting woven fabric does not show any shrinkage wrinkles (
A good composite fabric was obtained.

The difference in shrinkage rate between the weaving process and the final product in the composite fabrics obtained in Examples 1 and 2 is that the former is 0 in the warp direction.
．． 8%, and the latter is 0.8% in the weft direction, so there is almost no shrinkage in the direction using different types of fibers, and the effect of high temperature setting after weaving is also taken into account, all of the shrinkage wrinkles seen in the past (
This makes it possible to provide an excellent composite fabric that does not cause any oxidation.

(Effects of the Invention) According to the present invention, the occurrence of shrinkage wrinkles, which is a common drawback in composite fabrics using different types of fibers including raw silk, can be eliminated, and a composite fabric with an extremely beautiful finished appearance can be easily provided. Excellent, by applying high-temperature setting to different types of fibers in advance to give them approximately the same degree of shrinkage as raw silk, the difference in heat shrinkage can be minimized and shrinkage wrinkles can be reliably and easily overcome. This is a great advantage as it opens the way to providing tissue products of excellent quality and at an economical cost.
