BACKGROUND OF THE INVENTION 1. Field of the Invention [0001]

The present invention relates to a raw material pretreatment apparatus, and more particularly, to a raw material pretreatment apparatus which is disposed before a tentering process and shrinks a raw fabric while removing impurities from the raw fabric, By measuring the weight value of the fabric with the load cell and controlling the rotation speed of the drawing roller by using the inverter based on the measured weight value, it is possible to reduce the wrinkles and wrinkles of the fabric while inducing the conveyance of the fabric in the precise control state of the storage capacity, The present invention also relates to a pretreatment apparatus for a fabric having an improved structure.

Generally, the processing of fabric fabrics such as woven fabrics or knitted fabrics includes a heat setting process performed as a pre-dyeing process, a drying process performed as a post-dyeing process, And a tenter machine is mainly used as a device for carrying out such a process.

The entire length of the chamber is determined in accordance with the feed rate and processing conditions in the processing of the fabric raw material. The chamber is constructed by connecting a plurality of unit chambers having a length equal to the entire length. The cloth fabric inlet and the fabric fabric outlet are respectively provided in upper and lower end unit chambers provided at upper and lower ends of the unit chambers.

When performing the heat setting process, the drying process and the shrinking process by the conventional tenter device, when the blower and the heater are operated while the fabric is transferred, air in the chamber is sucked into the hot air generating duct through the heater by the blower, The heated air is heated by heat exchange with the heater to generate hot air of about 180 to 220 ° C. The generated hot air is supplied to the inside of the hot air spray nozzle through the hot air supply duct by the blower.

The hot air supplied to the inside of the hot air jetting nozzle is sprayed on the upper and lower surfaces of the fabric through a plurality of nozzle holes formed in the nozzle plate of the hot air jetting nozzle to perform a heat setting process, a drying process or a shrinking process.

However, it is preferable to pass the process of reducing and refining the fabric to a pleated state through the pretreatment process of the fabric prior to the drying process of the conventional fiber fabric. Such a pretreatment process is a continuous process of nylon and polyester filament yarns A continuous refining machine used for refining, and a relaxer processing machine used for shrinking and refining the polyester waxy fabric.

As a prior art related to a conventional reeler processing machine, there has been known a process for fabricating a reeler machine as disclosed in Korean Patent Registration No. 10-0416957 entitled " Apparatus and Method for Processing Continuous Moisture Setting Relaxer of Low Density Fabric "(Registered on January 17, 2004) , The fabric is loosened smoothly on the conveyor belt to remove the winding tension, and the fabric is firstly restored to its original shape, and then shrunk and set to guide it to the water immersion tank. The feed roller and the feed hopper And a water supply valve for supplying hot water to the inside of the water immersion tank, and a conveyor wire mesh and a conveyor roller are installed so as to be immersed in the water immersion tank at a certain depth So that the fabric is conveyed along the conveyor wire net, and at this time the steam is used as a heat source to maintain the water temperature And a plurality of injectors are installed on one side of the submergence tank so as to reduce, set and refine the fabric by spraying hot water from the upper part of the raw sewage, and a pump And circulation of the hot water is performed, and an overflow drainage device and an automatic water supply device for suspended float floating material are constituted.
