Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing self-produced fabric tubes with superior performance.

Conventionally, a so-called self-playing fabric containing a special Kli has been used as the Il fabric of a feather duvet, or as a fabric for fighting clothing of a nine-quilting cape for use in medium JIIK down ta.

In other words, if you use a regular cotton or mixed cotton futon or the fabric used for quilting, the down stuffed inside will stick out through the gaps in the fabric, significantly damaging the product value. As a countermeasure to this problem, a fine, high-density woven fabric is pressed between a pair of rollers using thin, high-quality yarn to crush the grains of the woven fabric, resulting in a fabric with a dense structure.

However, although fabrics with these measures have the effect of preventing the down from coming out, as a result of the strong crushing process, conventional fabrics tend to have a paper-like and hard texture, making them difficult to wear. The inside of the fabric makes rustling noises, doesn't fit well to the body, and the fabric is not very comfortable to use.

The present inventors have conducted intensive research with the aim of developing a new zero-ruin fabric that is excellent in both down protrusion prevention properties and Japanese texture in order to eliminate the above-mentioned drawbacks, and have arrived at the present invention.

That is, the present invention provides a single yarn with a high elongation of 11.8 denier or less,
A low-shrinkage continuous #I fiber bundle is supplied to a tension-cutting area where tension-cutting is performed in one or two stages to form a discontinuous fiber bundle, and a non-twisted or , a back-pressed binding yarn is used for the warp and/or #'i weft, the fabric cover factor CP is 25 to 35, and the basis weight is 1409/
There is a method for producing a self-woven fabric whose percentage value is to obtain a woven fabric of n/n or less, and then subject the woven fabric to high temperature and pressure processing.

The present invention will be explained in detail below.

The continuous fiber bundles used in the method of the present invention are
The filament is made of a filament having a denier or less, and it is more preferable to use a filament having a denier of O, S or less. When the single yarn fineness exceeds 0.8 denier, the number of constituent fibers of the non-twist binding yarn decreases,
Even if oral processing is applied, the effect will be halved.KT
.

Ru.

In addition, if the single yarn fineness exceeds 0.8 denier, the disadvantage that the fabric becomes stiff and stiff as a result of oral processing becomes stronger, so in any case, the single yarn fineness exceeds 0.8 denier. I don't like that.

Furthermore, it is important that the above-mentioned continuous wire bundle has high elongation and low shrinkage.

It is best to use a different elongation of 40 inches or more, and use KIIf or 10 inches above the embankment.
The shrinkage rate is preferably 3-3 or less expressed as a submerged shrinkage rate.

In addition, the types of continuous fiber bundles include polyprepyrene,
Synthetic fibers such as boria (dough polyester and acrylic) are effectively used, and polyester fibers are particularly preferred in terms of texture and heat fixability.

Next, the important point in the method of the present invention is that the limb continuity a
The method is to supply the i# bundle to a tension-cutting area where one or two stages of tension-cutting are performed to form discontinuous fibers, apply a fluid, and use untwisted or loose binding threads.

FIG. 1 shows that the continuous fiber bundle used in the method of the present invention is cut,
1 is a process diagram showing an example of the process of making a non-twist binding yarn, and to explain it clearly, 1 is made of a filament with a single yarn fineness of 0.8 denier (cutting elongation 60 inches, submergence shrinkage rate 2.8 inches) The continuous sl fiber bundle 1 is supplied to the tension cutting area 3 between the supply roller 2 and the tension cutting roller 40, and is made into a discontinuous spliced bundle 5 by one tension cutting, and then the continuous rutted fiber bundle 1 is made into a discontinuous spliced bundle 5 by one tension cutting. The discontinuous fiber bundle 5 is taken up by a take-up nozzle 6 that has a suction action and a swirling action, and is further passed through a joining nozzle that has an interlace action to join the discontinuous fibers 6 to form a non-twist binding yarn 9 and wind it in a winder 10. It is.

In the example in Figure 1, a -circle poem (i.e., a one-stage poem) is shown as the tension area, but there are also preliminary tension areas in which the tension is cut at a rate of several chi or more. Continuous K in the tension cutting area
Alternatively, the rollers may be provided with gaps between the rollers. However, the number of actual tension cuts, including preliminary tension cuts, is 1 to 1.
It is necessary to perform the process twice (ie, 1-2 stages).

In other words, if the skeleton section is a three-stage illusion, the same degree of stretching is applied to one of the stretched discontinuous fibers in the length direction, resulting in a continuous change in the length direction. Discontinuous fibers having a shrinkage rate cannot be obtained, and as a result, bulky yarns or fabrics made from the yarns as intended by the method of the present invention cannot be obtained, and the objective of the present invention cannot be achieved. .

The second reason for this recommendation is that the non-twisted binding yarn used in the method of the present invention is structurally shown in a nine-dimensional view, and the individual ruts la constituting the non-twisted binding yarn differ along the direction of rutting. , and has a variable shrinkage rate, so that among the non-twist bound yarns, the bulky yarn has a different form from the conventional bulky yarn that is a blend of high shrinkage fibers and low shrinkage fibers. becomes.

That is, in the #g2 diagram, one fiber #i, 1 indicated by a
．． Like a single spear, the untwisted binding yarn is arranged in the central part of the eastern part of the prefecture and the outer layer while migrating as appropriate, making it a yarn with good cross-pollination and conjugation of each fiber, and a high There is no hard core due to sagging, resulting in a yarn with good bulkiness.

Since such untwisted binding yarn is obtained using a special K, high elongation, low shrinkage continuous fiber bundle, it is necessary to carry out drafting at an extremely high pressure and at the same time when cutting the tension. Changes in residual strain during tension cutting due to drafting cause parts with a low shrinkage rate and parts with a high shrinkage rate to appear in one #fiber, and the difference in shrinkage rate (for example, submergence shrinkage rate) 3% or more).

In addition, in the method of the present invention, it is possible to use the above-mentioned non-twist binding yarn which has been given a twist with a twist coefficient of 2 or less. (Here, the twist coefficient is, especially when cutting a continuous dense fiber bundle, if the gap between the supply roller 2 and the tension cutting roller 4 is set long and the average fiber length of the staple fibers is 1501 or more, the binding yarn becomes Because the conjugation property is strengthened, it is possible to produce fibers with extreme twisting with a twist coefficient of 2 or less, or even with no twisting in some cases, and by making the twisting or non-twisting, the yarn is easily deformed in the cross-sectional direction, and This facilitates the migration of fibers, making it possible to further refine the woven structure.

In the present invention, such a plain or woven east yarn is used as a gauze yarn and/or a weft yarn, woven into a high-density woven fabric, and subjected to high temperature and pressure processing to obtain a 0-crumple fabric.

As the high-density fabric, a fabric having a fabric cover factor CF in the range of 26 to slI is effective. However, in particular, the fabric cover factor CF is determined by: If the fabric cover factor CF is less than 25, a fabric with a dense surface cannot be obtained, and there is no effect of preventing down from blowing out, making it impossible to achieve the object of the present invention.

On the other hand, if the cover factor CF exceeds 35,
Even if a fabric with a dense surface is obtained, the texture is poor and the weaving efficiency is reduced as a result of dense weaving, so it is not used. Because binding yarn is used, it is difficult to manufacture this type of zero-rubber fabric, which has traditionally been difficult.
/ m or less). In other words, the fist level is 0.
By using thin fibers of 8 denier or less and using untwisted to twisted binding threads, we are able to use fine-count binding threads and give the functionality of 0-crumple fabrics even to fabrics with a small basis weight. be.

In addition, the zero collapse fabric obtained by the method of the present invention has a very low degree of oral processing performed at temperature and pressure. Even when passed through a pressure roller VC of 5 to 1 crn, the Frazier air permeability (JI8L-1079) is 31-IJ4/
ttl, ・See the following 1-can be obtained.

IJT, Examples will be described.

Example Single yarn: 0.7 denier, elongation: 54 inches, submergence shrinkage: 0.
Full denier made of 9-polyester filament!
A continuous fiber bundle of Goo denier is cut in one day between a supply roller 2 with an interval of 60Q■ and a tension cutting roller 4 at a draft ratio of JIS times, and the average fiber length is 210 m, and the fiber bundle is cut into a total fII in an arbitrary cross section. A discontinuous and distinct fiber bundle was obtained in which the proportion of Rin fibers with a submerged contraction rate difference of 3 or more within single #I fibers was 76%.
Continuing to discontinue #! J! An air binding nozzle was applied to the 11 fiber bundle to form an interlace layer, thereby obtaining a non-twist binding yarn having a fine count of 40.

Next, 3.8 times/2.64 cpR (!

A plain weave of 2.54 cm, 478 threads/2.54 cnl (cover factor ζ29) is woven, dyed using the usual method, and then subjected to oral processing under lighter conditions than normal.

The following table shows the physical properties of the 0-depression fabric obtained above, as well as the results of making a feather comforter using the 0-depression fabric and using it for one month and conducting a usage test. For comparison, a normal spun yarn of cotton count 40 (twist coefficient 3.3) made by blending polyester and cotton at a ratio of 1:1 was used, and the linear density was 108 yarns/inch.

Latitude 80 / Inch (Cover factor ″; 30)
A similar test was conducted on a fabric that was dyed and milled using the usual method, and the results are also shown.

In addition, when the Frazier air permeability of the fabric produced by the method of the present invention was measured without being subjected to zero crushing processing, it showed a value of 2.0 ffl/--Hatake-gu, indicating that it had performance that could be used even without self-processing.

As described above, according to the method of the present invention, it is possible to obtain a one-year-old fabric with a good one-up effect, down-proof performance, and good hand KsL.
