The present invention relates to a front burnout or a half burnout processing method for a synthetic fiber fabric including ice velvet, and more particularly, chemicals for fiber burnout and coloring chemicals for formation of a pattern on the surface of synthetic fiber fabrics. The pattern is printed using a printing screen or roller of a specific pattern on which the mixed chemical is applied, and then heat-treated with a far-infrared heater for dyeing and printing drying. Front burn-out or half-burn of synthetic fabric fabric which can be done by sand-washing to dry the fabric after sandwashing to remove burnout residues and patterning through front burn-out or half burn-out and high temperature treatment at the same time It relates to an out processing method.

Burn out is one of the fabric processing methods, also called burn out, which means that the fiber is burned out. To explain a specific method of processing, first we mix two different types of fibers, the bottom fabric of which is a thin silk of plain weave such as organza, which uses a different warp on the surface to make an adverb or fluff, and then one of the fibers It is eroded and disassembled to create the desired pattern, and the underlying fiber (organza) is left untouched by chemicals, giving the impression of embroidering a colorful embroidery pattern on the mesh fabric. Representative fabrics produced by such processing methods include opal, georgette, and the like.

The two fibers commonly used in burnout processing are polyester fibers and cotton or viscose rayon fibers, which are printed with chemicals such as sulfuric acid, and dissolve cotton or rayon to create a permeable pattern leaving only polyester fibers.

Conventional burnout processing method is disclosed in the Republic of Korea Patent No. 297937 using a polyester yarn as a pile structure and a nylon yarn as the back surface structure is disclosed a burnout processing method for the fabric, the configuration of the invention is nylon 50% solution of liquid caustic soda and powdered caustic soda mixed with fiber and polyester fiber mixed with water, 20% water, 15-20% urea, 7-10% urea, 1 ~ 2% antifoaming agent Forming a pattern using a printing screen or a roller in which grooves are formed to form a pattern in medicine; A heating step for promoting a chemical reaction of the polyester fiber to the chemical on the fiber formed by the process; A process for removing a hardened portion by causing a chemical reaction in the pattern of the fiber heated by the process; Cooling the fibers to generate heat by causing a chemical reaction at the patterned portion by the process; It consists of a washing process for removing the remaining amount of synthetic fibers remaining by the chemical reaction in the fibers cooled by the above process.

However, in the conventional burnout processing method, when the front yarn is melted at a high temperature (170 to 190 ° C.) when the front yarn is melted using a strong chemical to the back yarn, it is inevitably low temperature (100 to 110 ° C.). Since it has to be treated at low temperature, the dyeing process requiring high temperature treatment must be performed separately after the burnout process, and the dyeing pattern is made according to the burnout pattern by dyeing through the two-step process. There is a drawback to being unable to fit.

In addition, the processing method for performing the burnout process and the dyeing process in one process is disclosed in the Republic of Korea Patent Application No. 10-2001-68555 a method of coloring burnout of the fabric, the composition of the invention is a polyester yarn and Preparing a blended fiber fabric comprising cotton yarn; In order to form a specific pattern by the chemical treatment on the surface of the prepared blended fiber fabrics to print the pattern using a printing screen or roller of a specific pattern on which a chemical mixed with a fiber burnout chemical and a coloring chemical step; Heat-treating to a predetermined temperature to promote chemical reaction of the chemical printed on the fabric; Washing the portion of the fiber tissue burned out by the heat treatment; Sand washing to cleanly remove the burnout residue remaining after the washing process; And after the sandwashing, drying the fabric to complete the product.

However, in the case of the present invention, even if the burnout and the coloring is made at the same time, the color is not clear and once dyed due to the heat of the fabric itself when each fabric is loaded after simultaneously performing the burnout and coloring operations on the sheet of fabric. This has the disadvantage of discoloring.

On the other hand, the Republic of Korea Patent No. 469011 discloses a burnout processing method of the polyester fiber is an object of the present invention in the burnout process is water-soluble instead of the acid salt of the inorganic acid and the inorganic acid known in the prior art and volatile at high temperature steaming and coloring Not only does it have a bad side effect on disperse dyes, but it is also used to effectively disintegrate and dissolve cellulose fibers to economically process fibers of vivid color.For this, oxalic acid, tartaric acid, malic acid, citric acid, glycolic acid, and gluconic acid are selected. It is characterized by using any one or more organic acids as a coloring agent.

However, even in the case of the present invention, once the burnout and the coloring work is performed on the fabric sheet at the same time, when the respective fabrics are loaded, the disadvantage that the dyed part is discolored due to the heat of the fabric itself cannot be overcome.

The present invention has been made in view of the above points, and when the burnout and dyeing are carried out at the same time, the dyeing and the texture of the fabric by heating and generating a constant temperature and wavelength in the dyeing and drying process in the drying process By using the far-infrared heater for dyeing and printing drying, which improves productivity as well as improving productivity, it is possible to perform pattern formation through front burnout or half burnout while simultaneously performing high temperature treatment to dyeing, thereby improving cost and design efficiency. You can increase it.

Therefore, an object of the present invention is to generate heat while generating a constant temperature and wavelength in the dyeing and drying process in the process of drying and steaming to improve the dyeing color and the texture of the fabric as well as far-infrared for dyeing and printing drying to improve the productivity To provide a front burnout or half burnout processing method of a synthetic fiber fabric including ice velvet that can be performed at the same time by forming a pattern through front burnout or half burnout by using a heater and simultaneously performing high temperature treatment to dyeing. have.

The object of the present invention is a pattern using a printing screen or roller of a specific pattern on which the chemicals mixed with the fiber burnout chemicals and coloring chemicals to form a pattern on the surface of the synthetic fiber fabric including ice velvet By printing and then heat-treating with a far-infrared heater for dyeing and printing drying, and then washing the part where the fiber tissue was burned out by the heat treatment and drying the fabric after sandwashing to cleanly remove the remaining burnout residue. .

The front burnout or half burnout processing method of the synthetic fiber fabric containing the ice velvet of the present invention is a chemical burnout and coloring for the fiber burnout for the formation of a specific pattern by chemical treatment on the synthetic fiber fabric surface including the ice velvet Printing a pattern using a printing screen or a roller of a specific pattern on which the chemicals are mixed; Heat-treating with a far-infrared heater for dyeing and printing drying to accelerate the chemical reaction of the chemicals printed on the fabric to perform burnout and coloring; And washing the portion of the fiber tissue burned out by the heat treatment.

Further sandwashing to cleanly remove burnout residues remaining after the flushing treatment; And after the sandwashing, may further include drying the fabric.
