Description

TECHNICAL FIELD The present invention relates to quilted fabrics. For more details,
TECHNICAL FIELD The present invention relates to a quilted cloth having a surface having a concavo-convex shape and having excellent shape-retaining property of the concavo-convex shape.

[Prior Art] Conventionally, various quilted fabrics have been used for clothing, outer fabrics such as sofas and chairs, and skin materials. With the diversification of quilted fabrics in recent years, it has a soft texture. However, it is desired that the surface material has a concavo-convex shape and is excellent in design.

Therefore, in response to such a request, an attempt has been made to obtain a quilted fabric in which the uneven shape of the outer material is remarkable by increasing the thickness of the inner material sandwiched between the outer material and the lining. If the value is increased, there will be problems such as when the outer material, batting and lining are sewn and integrated, the batting will shift and become uneven, resulting in uneven unevenness, and inability to sew at the desired position on the outer material. Therefore, a quilted cloth having a desired sewing shape and a remarkable uneven shape has not been developed yet.

[PROBLEMS TO BE SOLVED BY THE INVENTION] Therefore, as a result of intensive studies conducted by the present inventors in view of the above-mentioned prior art, it is obvious that the present invention has not only a target sewing shape and a remarkable uneven shape, but also an excellent wind. For the first time, a completely new quilted fabric having a certain combination was found, and the present invention was completed.

[Means for Solving the Problems] That is, the present invention is a quilted fabric in which batting is sandwiched between an outer material and a lining and then sewn into an integrated body, and a hydroentanglement containing heat-shrinkable fibers as a lining material. The present invention relates to a quilted fabric characterized by using a heat-shrinkable base fabric selected from a non-woven fabric and a spun-bonded non-woven fabric, sewn and integrated, and then heat-treating the heat-shrinkable base fabric to shrink it.

[Operations and Examples] As the outer material used for the quilted cloth of the present invention, the same outer material as that used for a normal quilted cloth is used, and the present invention is not limited to such outer material. As specific examples of such a surface material, for example, woven cloth, tricot, knitted cloth such as raised tricot, plain woven cloth,
Examples thereof include woven fabrics such as velour-like woven fabrics, non-woven fabrics, and the like, and there is no particular limitation on the thickness or the basis weight. As the fibers used for the outer material, for example, polyester fibers, polyacrylonitrile fibers, polyvinyl chloride fibers,
Examples thereof include synthetic fibers such as polyvinylidene chloride fibers and polyamide fibers; regenerated fibers such as rayon fibers and acetate fibers and semi-synthetic fibers; natural fibers such as cotton and wool, and mixtures thereof. Among these, polyester fibers, polyamide fibers, cotton, wool, etc. are particularly preferable because they do not easily shrink when heat-treated.

The batting used in the quilted fabric of the present invention is the same as the batting used in ordinary quilted fabrics, and the present invention is not limited to such batting. Such batting includes, for example, a fibrous web obtained by carding and accumulating fibers, or a fibrous web to which an adhesive resin such as an acrylic resin or a polyester resin is adhered by about 5 to 20%. Suitable fibers used for the batting are, for example, polyester fibers, polyamide fibers, polyacrylonitrile fibers, rayon fibers, cotton and wool.

In the present invention, it is preferable that the batting contains latent crimpable fibers whose number of crimps is increased by heating, for example, polypropylene, polyamide resin, polyester resin, or the like. By doing so, when the heat treatment is performed, the crimp of the latently crimpable fiber is developed to increase the bulk, and it is possible to sufficiently fill the space of the convex portion of the outer material caused by the shrinkage of the lining. In this case, it is preferable that the latent crimpable fiber is contained in an amount of 5% by weight or more, particularly 10% by weight or more.

Specific examples of the latently crimpable fibers include side-by-side type, core-sheath type, and eccentric type composite fibers composed of resins of two or more components having different melting points. Sheath type polyester conjugate fibers are preferred. Such a core-sheath type polyester composite fiber has a melting point of 24
A core-sheath type composite fiber comprising a core component made of a polyester resin having a temperature of 0 to 260 ° C and a sheath component made of a polyester resin having a melting point of 110 to 200 ° C.

There is no particular limitation on the basis weight and thickness of the batting, the texture of the desired quilting fabric, appropriately adjusted according to the shrinkage ratio of the heat-shrinkable base cloth, etc., but usually the thickness is 0.5 kg / cm load. ¹ to 40 mm when applied to ^{2, 3} to ² especially
It is 0 mm, and the basis weight is 10 to 90 g / m ² , 20 to 70 g
/ m ² is desirable. If the thickness is thinner than this or if the basis weight is small, the convex part is not filled with fibers sufficiently and the shape retention is poor. On the other hand, if the thickness is thicker or the basis weight is larger than this, sewing processing is performed. Difficult and not suitable for clothes.

Examples of the heat-shrinkable base fabric used as the lining of the quilted fabric of the present invention include hydroentangled nonwoven fabrics and spunbonded nonwoven fabrics containing heat-shrinkable fibers. Since the non-woven fabric has a three-dimensional porous structure, it is less likely that cotton will come off than the knitted fabric, and the content of the heat-shrinkable fiber can be freely set. However, when a non-woven fabric is used, heat which causes shrinkage of the heat-shrinkable fiber should not be applied in the manufacturing process. A so-called hydroentangled nonwoven fabric produced by intertwining fibers using a high-pressure water stream,
Since heat above the temperature for drying water is not applied during the process, the heat-shrinkable fiber does not shrink and has strength. In addition, so-called spunbonded non-woven fabric, which is produced by accumulating spin-stretched filaments, is also suitable as a heat-shrinkable base fabric. The one used is used.

In the present invention, the heat shrinkable fiber means a fiber having a dry heat shrinkage rate of at least 15% or more. Here, the dry heat shrinkage ratio of the fiber is a state in which the fiber is crimped before and after the fiber is placed in a hot air dryer at 150 ° C. for 15 minutes and then left for 2 hours or more in a standard state. Is a value obtained by dividing the difference in length before and after the treatment by the length before the treatment and showing the percentage. The heat-shrinkable fiber, for example, polyester, polyamide, polyvinyl chloride, when forming the fiber from a thermoplastic resin such as polypropylene, by adjusting the spinning conditions and stretching conditions, by not performing heat setting, etc.,
A fiber having a high degree of shrinkability by adjusting the crystallinity, orientation, and heat history of the fiber is used. Generally, the resin used for the heat-shrinkable fiber has a lower softening point than that of the resin forming the general fiber used for clothes so that the resin shrinks at a predetermined processing temperature. When the heat-shrinkable fiber is heated to a predetermined temperature, strain in the fiber due to stretching or the like is relaxed and a high degree of shrinkage occurs. The content of such heat-shrinkable fibers is appropriately adjusted according to the shrinkage of the desired heat-shrinkable base fabric. Therefore, in the present invention, the heat-shrinkable base cloth may be composed of only heat-shrinkable fibers in order to most effectively develop the shrinkage rate of the heat-shrinkable base cloth.

Examples of the fibers other than the heat-shrinkable fibers contained in the heat-shrinkable base fabric include regenerated fibers such as rayon fibers and acetate fibers, natural fibers such as cotton and wool, and heat shrinkage ratios for performing heat setting in the manufacturing process. Examples include small synthetic fibers, that is, ordinary synthetic fibers, but the present invention is not limited to these fibers.

The shrinkage ratio of the heat-shrinkable base fabric is preferably adjusted appropriately by adjusting the blending amount of the heat-shrinkable fiber according to the height of the convex portion usually formed on the outer material, and in the present invention, such shrinkage The rate varies depending on the type of heat-shrinkable fiber, but when heated in air at 130 ° C for 1 minute, it should be at least one direction in the plane, preferably 20 to 70% in all directions, especially 30 to 70%. Is desirable from the standpoint that quilting can cause remarkable unevenness.

When the heat-shrinkable base fabric having such shrinkage is integrated with the batting and the outer material and subjected to heat treatment to make a quilted cloth, the shrinkage of the quilted cloth is the thickness of the batting,
Depending on the type of surface material and quilting pattern, it will be 10-60%, especially 15-60%.

The thickness and basis weight of the heat-shrinkable base fabric are not particularly limited, but usually the thickness is 0.15 to 1.0 mm, especially 0.2 to
0.7mm, weight is 10-100g / m ² , 20-50g / m ²
It is desirable that it is a degree.

The batting is sandwiched between the outer material and the lining and then sewn. The sewing means is not particularly limited in the present invention, and may be a sewing machine which is usually used. The sewing shape is not particularly limited in the present invention, and it is preferable to appropriately adjust it according to the sewing pattern of the target quilted cloth.

The sewn-integrated quilting fabric is then subjected to heat treatment, and the heat-shrinkable base fabric is heat-shrinked. Conditions for causing such heat-shrinkage include, for example, air and water vapor at about 90 to 150 ° C. Heating for 30 seconds to 10 minutes by using air etc. can be mentioned.

Thus, by heat-treating the quilted fabric in which the outer material, the batting and the heat-shrinkable base cloth are sewn together, the heat-shrinkable base cloth is heat-shrinked, and the uneven shape of the outer material becomes more remarkable. Further, the heat-shrinkable base fabric is pushed up in the direction of the outer material by heat shrinkage, and the convex parts of the outer material are filled with the inner material, so that the original shape is restored even when pressed.

Next, the quilted fabric of the present invention will be described in more detail based on examples, but the present invention is not limited to these examples.

Example 1 Polyester fiber having a dry heat shrinkage of 50% (fineness: 1.9 denier, fiber length: 51 mm) 60% by weight and polyester fiber having a dry heat shrinkage of 1.6% (fineness: 1.5 denier, fiber length: 38 mm) 40% by weight Heat of a hydroentangled non-woven fabric in which fibers are entangled by treating a fibrous web with a basis weight of 30 g / m ² consisting of and with a high-pressure water stream with a water pressure of 50 kg / cm ² formed by ejecting water from multiple nozzles. A shrinkable base fabric (shrinkage rate: vertical 55%, horizontal 50%) was obtained.

On this heat-shrinkable base fabric, a polyester web (fineness: 2 denier, fiber length: 51 mm) with a basis weight of 30 g / m ² fiber web with acrylic resin 5 g / m ² attached (load 0.5 g / cm 2
² thickness is applied: 6.5mm), then the outer material (nylon taffeta) is placed on it, and then sewing is performed using a sewing machine so that the sewing shape shown in Fig. 1 is obtained. The outer material (1), the batting (2) and the heat shrinkable base cloth (3) were integrated to obtain a quilted cloth.

Fig. 2 shows a cross-sectional view of the obtained quilted cloth taken along the line AA.

Next, the quilted cloth is heated to 130 ° C using a pin tenter.
The heat-shrinkable base cloth was shrunk by heating for 1 minute to obtain the heat-shrinkable quilted cloth of the present invention. The heat-shrinkage of the obtained heat-shrinkable quilted fabric is 20% vertical and 10% horizontal.
Met. In addition, FIG. 3 shows a cross-sectional view of the heat-shrinkable quilted cloth taken along the line BB in FIG.

As is clear from the results of FIG. 2 and FIG. 3, since the quilted fabric of the present invention uses a heat-shrinkable base fabric, heat-shrinking the quilted fabric makes it difficult for the outer material (1) to be complicated. When unevenness occurs, the height of the convex portion of the outer material (1) is remarkably raised from 4.7 mm to 6.8 mm, and the convex portion inside the outer material (1) is filled with batting (2) without any gap. I understand.

Example 2 As a heat-shrinkable base fabric, a polyester spunbonded nonwoven fabric having a basis weight of 60 g / m ² and a thickness of 0.70 mm (heat shrinkage rate: vertical 50%, weft
45%) was used, and a quilted cloth was prepared in exactly the same manner as in Example 1.

The heat shrinkage of the obtained quilted fabric is 18%, horizontal
10%, and as in Example 1, remarkable unevenness was formed,
The convex part was filled with batting. However, the quilted fabric of Example 2 had a slightly harder texture than that of Example 1.

Example 3 As a fiber constituting the batting, a latent crimpable polyester fiber (fineness: 2.5 denier, where the number of crimps increases from 14 crimps / inch (about 2.54 cm) to 45 crimps / inch when heated at 170 ° C. for 3 minutes Fiber length: 51 mm) and 1 quilted fabric
A quilted fabric was produced in the same manner as in Example 1 except that the latent crimpable fiber was subjected to shrinkage treatment at 170 ° C. for 1 minute after shrinkage treatment at 30 ° C. for 1 minute.

The heat shrinkage rate of the obtained quilted fabric is 20%, horizontal
Although it was 10%, the elasticity and tension of the convex portion were larger than those in Example 1.

[Effects of the Invention] The quilted fabric of the present invention has very prominent irregularities and is excellent in design, and since the inside of the convex portion of the outer material is filled with batting, the shape retention and softness are maintained. Since it has an excellent feeling, it can be suitably used, for example, as a surface material of a sheet or a clothing material.

Further, since the quilted fabric of the present invention has excellent shape-retaining property, it does not easily lose its shape even if it is subjected to dry cleaning or washing, and it has excellent dry cleaning resistance and washing resistance.
