Description

TECHNICAL FIELD [0001] The present invention relates to a recycled polyester yarn, and more particularly, to a composite yarn using recycled polyester yarn and a method for manufacturing a blind fabric using the recycled polyester yarn.

More particularly, the present invention relates to a low-melting fiber (hereinafter referred to as "LM yarn") and a recycled polyester The present invention relates to a method for manufacturing a multi-woven fabric for blinds having excellent light-shielding property and heat-insulating property by using a dobby loom or a jacquard loom using the above-mentioned method.

In the past, the interior has been modified by changing curtains, curtains, sofas, etc., but nowadays, the blinds are noticed easily, and UV rays, light control and privacy protection functions can be utilized. We can produce various atmosphere of the sun,

In general, curtains and blinds are installed at the windows or entrance of a building, and are used for the purpose of blocking infrared rays and ultraviolet rays, blocking external eyes, soundproofing, and preventing cold. In addition to this practicality, It is used as an important element of interior decoration that improves indoor aesthetic according to the combination.

In particular, blinds have been popularized four to five years ago when the system window was generalized, and the curtains that were needed to prevent the outdated winds were replaced with system windows, but the necessity of UV shielding and light control Recently, however, the use of blinds has been increasing for the protection of public hall.

Recently, as the interior decoration industry has developed and many people have started to attract attention, interior decoration items have been diversified. In recent years, home interior has become a big buzzword. .

Among them, the curtains that have various advantages such as protecting the privacy of the sun, protecting privacy, and creating a home atmosphere have been developed and developed in the form of blinds, and there are many housewives who are different from each other As the best item is getting popular.

The blinds are made by roll screens (rolled blinds, screens wrapped around a bar-shaped central axis), veneers, verticals, pleated wrinkles, and honeycomb And the profile of a honeycomb in the side view. The most commonly used items in homes and offices are roll screens, verticals, and wood blinds, and they tend to prefer products that are not burdensome in terms of design and price.

The roll blind saves the heating and cooling costs by adjusting the amount of light and heat. It protects the cooling air temperature by keeping the strong direct sunlight in the summer and protects the warm indoor air in winter. It plays a role.

The roll blind is a shading device that is made of light, flexible reeds, grates, small plates, etc. to be installed on the outside so that they can be made by wire making and rounding or folding. This device is attached to the bottom of the eaves, the protruding beam of the shade, and the independent pole. Most of them are controlled by the pole.

Curtains are gradually being replaced by blinds and roll blinds in the interior products. The fabric part of the roll blinds is generally made of polyester, and the resin is bonded to the fabric so that it is unavoidably coated Process.

The blinds block solar radiation in summer and the effect of solar radiation and nighttime insulation in winter. In addition, individual windows can be shaded individually, and partial blocking is possible even when the window is exposed only to the window. And you can apply different types depending on the material, with colorful colors and textures.

In the case of roll screen fabrics for existing roll blinds, the silver back coating used for the glass material on the back side is not only heavy but also far from eco-friendly materials, and when organic solvent is coated and treated on the fabric It is difficult to uniformly penetrate into the inside of the fabric, so that there is a tendency to cause a difference in adhesiveness and light texture, and the material used contains many volatile carcinogens, which is detrimental to the human body.

In order to solve these problems, a new technique which shows the curing characteristic without coating process by the post-process heat treatment has been developed and applied. In addition, the color and the design pattern are applied variously, It is a trend to use eco-friendly materials as a matching product, to enhance the aesthetics and to use very luxurious materials.
