Abstract

PURPOSE: A method for manufacturing a coating cloth using liquid silicon is provided to enable the coating cloth to exhibit improved extendable property and good tear resistance and to maintain a waterproofing property even after repeated contact with water during cleaning. CONSTITUTION: The method comprises: primarily coating a mixture containing liquid silicon as a main component on a fabric sheet adhered to a print plate by silk printing; drying the primarily coated fabric sheet at 100-200 deg.C for 1-5 minutes for curing; secondly coating the mixture on the cured fabric sheet by silk printing; and placing a desired pattern or design mold on the resultant sheet, drying and curing the same while pressing using a hot press.

Description

Method for manufacturing coating fabric using liquid silicon {Method for manufacturing the coating cloth using in liquid silicon}

The present invention relates to a coating fabric for waterproofing through a coating applied to the fabric, and in particular, to a liquid silicone which is excellent in elasticity and maintains waterproofness by applying and drying a coating consisting of liquid silicone on the fabric. It relates to a method for producing a coated fabric used.

In general, fabrics used for sports or leisure, such as swimming caps, sportswear, health clothing, swimwear, aerobics, etc., should have the appropriate functionality for each characteristic compared to the usual clothes, these coatings are excellent elasticity and health A harmless coating should be attached or coated.

For example, coating fabrics such as swimming caps are used in buoyant water, so they must satisfy the condition that they do not come off from the head during swimming. Manufactured fabrics.

By the way, the coating fabric is a structure in which the coated paper is pressurized and coated with the waterproof paper and the stretchable paper, and the coated paper is simply maintained by heat or pressure, so that the coated paper is easily torn due to lack of elasticity. Not only did not use its own function, but also the loss of waterproof performance was feared.

Thus, the present invention was devised to solve the problems as described above, the production of a coating fabric using a liquid silicone that can maintain a waterproof and excellent waterproof by applying a coating material of the liquid silicone to the base material The purpose is to provide a method.

In order to achieve the above object, the present invention provides liquid silicone 60 to 80 wt%, curing agent 5.0 to 10 wt%, silicone oil 10 to 30 wt%, and medium to 0.1 to 2.0 wt%. The mixture is first applied by silk printing and then dried for 1 to 5 minutes at 100 to 200 ° C. to be cured, and then the mixture is secondly printed by silk printing on the dried fabric, and then the desired pattern and character is placed on the upper side thereof. It is characterized in that the hardened by drying again while pressing with a hot press in the state of seating the mold.

Hereinafter, an embodiment according to the present invention will be described in detail with reference to the accompanying drawings.

First, the mixture used in the present invention is a liquid silicone as a main material and a hardening agent, a silicone oil and a tracer agent are added in a small amount, and in particular, the mixture is preferably coated by a silk printing method. Naturally, the mixture may be applied using a jig.

In addition, in the process of applying the mixture to the fabric, it is natural that the liquid may be applied while stirring for a set speed and time by depositing in a state in which the liquid silicon is accommodated in a storage tank (not shown) instead of the silk printing method.

In addition, the content of the curing agent included in the mixture may be included in a different content depending on the type of the original paper, depending on the quality and curing time of the final product may be included in a weight ratio of 5.0 to 10wt% or more or less.

In addition, since the liquid silicone may be exposed to air and solidified in the process of drying the mixture, it is preferable to maintain the airtightness of the dryer as much as possible and to include the minimum amount of the curing agent.

In addition, in the course of drying after the second coating of the mixture, it is natural that it may be dried using a conveyor, for example instead of a hot press.

Hereinafter, the operation according to the present invention will be described in detail.

First, when the mixture is to be applied to the fabric paper and waterproofed, the components of the mixture are first blended in a weight ratio of 60 to 80 wt% of liquid silicone, 5.0 to 10 wt% of curing agent, 10 to 30 wt% of silicone oil, and 0.1 to 2.0 wt% of the middle agent. Of course, the process of fixing the original paper flat on the printing plate should be made in advance.

Then, the mixture is applied to a desired thickness by using a silk printing method on the original paper fixed on the printing plate. Of course, it is preferable to automatically adjust the supply amount and the number of times of printing using the silk printing method.

Subsequently, hot air is blown in a state where the raw paper coated with the mixture is inserted into the drying apparatus, dried at 100 to 200 ° C. for 1 to 5 minutes, and cured. At this time, it is preferable to maintain the closed state as possible when using a drying apparatus.

Then, the mixture is applied to the desired amount by the silk printing method on the original fabric dried by a dryer or hot air, and then a piece mold having a desired pattern or character is placed on the upper side of the mixture.

Subsequently, the liquid silicone is applied to the upper surface of the engraving mold, and then the original paper to be marked on the upper side is folded, and the temperature range of the hot press is set to 100 to 200 ° C., and the pressure is dried. This is done.

As described above, according to the manufacturing method of the coating fabric using the liquid silicon according to the present invention, since the coating material is prepared by applying liquid silicon to the fabric two times and applying heat, the elasticity of the coating fabric is improved and the external force is improved. In addition to minimizing the tearing phenomenon by the water-washing, the waterproofness is maintained, so that the convenience of maintenance and management of the product is provided.

Claims (2)

On the original fabric attached to the printing plate, the liquid silicone-based mixture is first applied by silk printing, and then dried by curing at 100 to 200 ° C. for 1 to 5 minutes, and then the mixture is further silk on the dried original fabric. The method of manufacturing a coating fabric using liquid silicone, characterized in that the drying and curing while pressing with a hot press in a state in which the desired pattern and the engraving mold of the character on the upper side after printing and coating. The method of claim 1, wherein the mixture, The composition ratio is 60-80 wt% of liquid silicone, 5.0-10 wt% of hardening | curing agent, 10-30 wt% of silicone oil, and 0.1-2.0 wt% of a middle weight agent.
