Method for continuously manufacturing sponge sheet for powder puff

Abstract

The present invention relates to a method for continuously manufacturing a sponge sheet for a powder puff, comprising: a coating step for coating a fabric using a mixed solution; a solidification step for solidifying the coated fabric, which has been coated with the mixed solution, in a solidification bath; a cleaning step for cleaning the fabric, which has passed through the solidification bath, in a cleaning bath; a coated fabric manufacturing step for carrying out a heat dry step for drying the fabric which has passed through the cleaning bath and then winding the fabric; a coated fabric buffing step for buffing the coated fabric, which has passed through the coated fabric manufacturing step, using a buffing roller and then winding the coated fabric; and a separation step for separating the fabric from the buffed and coated fabric and winding the fabric separately from a sponge sheet for a powder puff. Accordingly, there are provided effects that a sponge sheet for a powder puff can be continuously manufactured during a process time within a day, and a buffing method is selected instead of a slicing method so that processing is possible even though the thickness becomes smaller, thereby manufacturing various sizes of sponge sheets for a powder puff.

Description

technical field [0001] The present invention relates to a continuous method for producing a sponge sheet for a puff, and more specifically, to a method for continuously producing a sponge sheet for a puff having the effect that the sponge for a puff can be produced within a process time of less than one day Continuous production of sheets, and can be processed into thin thickness through continuous process. Background technique [0002] In general, a powder puff is a tool that women use to apply liquid foundation, concealer, etc. on their faces. Such a puff preferably has an appropriate air cushion so that it is stretchable and does not damage the skin, and is usually made into a sponge shape in which raw materials are foamed and molded. [0003] As a prior art related to this, Korean Patent Publication No. 1999-0075934 discloses a sponge puff and its preparation method, in which it is disclosed that the foaming process is repeated so as to have a denser and finer unit stru...

Problems solved by technology

[0004] However, the above-mentioned existing literature is a method of preparing sponge puff by batch system (batch system), for example, by putting in raw materials, performing a reaction or operation for a certain period of time, and then performing a discontinuous method such as subsequent processes to prepare puff There is a problem that the process time is too long

[0005] Generally speaking, the thicker the thickness of the mixture, the longer the setting time will be proportional to this. However, in terms of batch method, since the thick thickness is applied at one time, it takes 15 minutes for the setting time. Days to 30 days, so it takes a long time to prepare sponge sheets for puffs. In order to realize mass production, it has the disadvantage of requiring multiple machines

[0006] However, the reason why only the batch method can be used so far is that the viscosity of the mixed solution is very high, which is 200,000 to 400,000 cps / 25°C, so that the fluidity is low, and it is difficult to realize continuous coating, and for slicing, The thickness needs to be prepared very thick

[0007] In addition, the existing technology needs to be produced according to batch sizes, so there is a disadvantage that puff sheets of the required size cannot be produced
