Fabric for blinds with excellent heat insulation and light weight {Fabric for roller blind}

The present invention relates to a textile fabric for blinds, and more particularly, it is composed of a multi-layer, excellent thermal insulation, light weight, easy to handle, excellent decorative properties with a three-dimensional appearance effect, particularly suitable for fabrics for blinds as a roll blind fabric It is about.

Recently, with global warming, technologies and products related to energy saving for suppressing carbon dioxide generation are attracting attention.

As a result, blinds and other interior products are shifting from their preference for basic functions such as awnings or products that pursue only decorative effects, and thus changing their preference to products with improved functionality such as thermal insulation for energy saving. have.

In order to develop a product for improving the thermal insulation, it is basically possible to achieve the primary purpose by making a thick material using a high thermal insulation fiber material, but not only can not ignore the problem of the cost of the material selection, natural light It is also not a simple matter to develop a product that combines not only functionality for energy saving but also such merchandise as other merchandise issues such as durability, decoration, etc. must be taken into consideration.

For example, roll blinds include a system including a blind fabric and a roller for winding it up. If the fabric is made thick or heavy for warmth, the so-called rolled portion is too thick to make the system larger. Therefore, not only is not good appearance, but when installed in a large and long window, the weight of the textile paper can be a problem because the support or operation of the system is not made smoothly.

The present invention has been made to solve the problems in the above-described conventional fabric for blinds, excellent thermal insulation and light weight, do not overload the system, especially when rolled up, the volume is smaller, roll roll as an interior product as a whole It is an object of the present invention to provide a new type of fabric for blinds that does not compromise the decorative properties of the fabric.

The configuration of the fabric paper for blinds excellent in heat retention and light weight according to the present invention for achieving the above object,

In the form of a multi-layer fabric in which two or more fabric layers including a support layer and an elastic layer are integrated,

Some of the warp or weft yarns constituting the fabric layers intersect with each other to form a multi-layer fabric form in which each fabric layer is joined to each other.

The elastic layer is configured to form a convex-shaped space between the support layer bonded using a yarn having excellent elastic recovery,

When the coil is wound on the roller, the elastic layer is pressed and the space is extinguished, so that the thickness becomes thin. When it is unfolded, the elastic layer is elastically recovered, and the thermal insulation performance is exerted by the air layer formed in the three-dimensional space between the support layer and the high elastic layer. It is done.

The fabric for blinds according to the present invention forms a space between the elastic layer and the support layer having excellent elastic recovery property to form an air layer in the space, while having excellent heat insulation and light weight, and free deformation of the elastic layer and compression and elastic recovery. When unfolded by the three-dimensional appearance of the beautiful decorative appearance, and when rolled up to maintain a thin compressed form does not harm the overall appearance of the blind. Therefore, the blinds having both functionality and decoration can be manufactured using the same.

In particular, the blind fabric paper according to the present invention is configured in the form of a multi-layer fabric integrated by the joint portion, the multi-layered by the stitching in the weaving process without a separate sewing or bonding process for forming a three-dimensional multi-layer fabric In addition, since the three-dimensional shape can be expressed through the machining process, the manufacturing process is simple and the manufacturing cost can be reduced, and the uniformity of quality can be ensured.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the fabric paper for blinds according to the present invention.

Figure 1a is a view showing the cross-sectional shape in the dough state of the fabric paper for blinds according to an embodiment of the present invention, Figure 1b shows a cross-sectional shape in the processed paper state, Figures 2 to 3 of the present invention The cross-sectional shape in the processed paper state of the textile paper for blinds according to another embodiment is shown.

First, referring to FIGS. 1A to 1B, a blind fabric 1 according to the present embodiment includes three layers of a support layer 10, an elastic layer 20, and an intermediate layer 30. It consists of.

Each of the fabric layers 10, 20, and 30 are woven to form a separate layer, which is mostly separated from each other by using inclinations supplied from three different inclination beams, and crosses the inclinations at intervals of about 5 cm. It is configured to be joined.

Here, the inclination supplied from each of the inclined beams is a PET high shrink yarn 90d for the support layer 10, 0.2 mm PET mono yarn having excellent rebound elasticity and low shrinkage is used for the elastic layer 20, the intermediate layer ( 30) used a low shrinkage general PET flame retardant yarn of 150d, and prepared inclined number of 9000, 3000 and 3200, respectively. As the weft yarn, 150d PET flame retardant yarn and 150d PET low temperature fusion spliced yarn were prepared, respectively, and weaved by weaving so as to be alternately arranged 1: 1.

This woven fabric is a multi-layered fabric in which three fabric layers are bonded to each other at a predetermined interval in the bonding portion X, as shown in FIG. 1A, in which a small unevenness is formed by stitching, but is generally flat. Is done.

Then, after washing the woven fabric in hot water of 50 ~ 70 ℃, heat treatment while over feeding more than 30% in a tenter of 160 ~ 180 ℃, used as a slope of the support layer 10 as shown in Figure 1b The constricted high shrink yarn is convexly curved in the elastic layer 20 and the intermediate layer 30 having a relatively small shrinkage around the joints X connected to each other to form a space A therein. In addition, since the surface of the low-temperature fusion yarn used as the weft in the heat treatment process is softened and fused with the inclined cross, the mechanical properties are improved, and in particular, it is possible to secure the shape stability during compression and recovery of the elastic layer 20. .

The blind fabric paper 1 thus processed can contain a large amount of air in the space A formed between the support layer 10 and the elastic layer 20, and has excellent heat retention and light weight. do.

However, at this time, since the intermediate layer 30 uses a general PET yarn rather than a high elastic yarn, as shown in FIG. 1A, by weaving the warp in a somewhat tense state, the intermediate layer 30 has a flat state than the support layer 10 or the elastic layer 20 in a dough state. After processing, only a few bends are formed. The intermediate layer 30 is intended to supplement the decorative effect or warmth, it may be omitted as in other embodiments described later.

2 is a view showing a cross-sectional shape in the processed paper state of the fabric paper for blinds according to the second embodiment of the present invention.

The blind fabric paper 2 according to the present embodiment is provided with elastic layers 20 and 20 'on both sides of the support layer 10. Blind fabric paper 2 according to the present embodiment has the advantage that the space (A) is formed in two places to maximize the heat retention. The constituent yarn, weaving and processing of each fabric layer such as the support layer 10 and the elastic layers 20 and 20 'may be the same as those of the first embodiment described above or may be applied by applying the same. The same applies to the embodiment.

Figure 3 is a view showing a cross-sectional view in the processed paper state of the fabric paper for the blind according to the third embodiment of the present invention in the form of reinforcing the support layer using a separate ultra-high strength yarn.

In the blind fabric paper 3 according to the present embodiment, the ultra-high strength yarn 40 made of fibers such as aramid fibers, kevlar fibers or Dyneema fibers on the back side of the support layer 10 at intervals of about 5 to 10 cm. It arrange | positions and it is comprised so that the tension of a diagonal direction may be disperse | distributed when reinforcement of the support layer 10 is needed, such as when a window is large and a blind is especially long.

The ultra-high strength yarn 40 may be arranged to be woven so as to be connected to the support layer 10 at predetermined intervals by supplying it from a separate inclined beam as shown in FIG. 3, or may be arranged at predetermined intervals or entirely on the inclined beam of the support layer 10. By arranging, the support layer 10 can also be reinforced. On the other hand, if the use rate of the ultra high strength yarn, such as the use of such a super high strength yarn in the entire slope may have a function to prevent external hazards.

First, when the blind fabric paper 4 is unfolded, as shown in FIG. 4A, the window is covered with one end fixed to the roller 110 installed in the upper bracket 120 of the roll blind 100 to realize shading and indirect lighting. do.

The blind fabric paper 4 according to the present embodiment is the most basic form consisting of two fabric layers of the support layer 10 and the elastic layer 20, and is formed between the support layer 10 and the protruding elastic layer 20. The space (A) exhibits a thermal insulation effect, which is excellent in heat retention and practical in lightness compared to the case of using a thick paper of a general form and light weight in comparison with the volume.

On the other hand, if the roll blind is wound up as shown in Figure 4b, as the elastic layer 20 is pressed and compressed, the space (A) is minimized so that the volume of the state wound on the roller 110 becomes relatively very small compared to when unfolded It is not necessary to form a bracket 120 for accommodating it largely, so that the shape of the roll blind 100 as a whole is not cluttered, thereby impairing the decorativeness.

When it is unfolded again in the state of FIG. 4A, the high elastic yarn of the compressed elastic layer 20 recovers its original shape while elastically recovering, and the space A is formed again, resulting in a roll blind having warmth and three-dimensional decorativeness.

On the other hand, in all the embodiments described above, for example, the use of high shrink yarns, high elastic yarns, etc. in the inclined direction and described in the longitudinal direction in the form of a blind fabric is formed in a predetermined interval, for example, the configuration of the warp and weft yarns are changed or It is also possible to produce blind fabrics in which both yarns have different shrinkage ratios so that irregularities are formed in both directions.
