Description
SPECIFICATION
A process for treating wet-cleanable silk fabrics
The Field of Application of the Invention
The present invention relates to a novel process for treating silk fabrics with water repellent to produce dry- and wet-cleanable silk products which do not stick to the skin and won't be bleached or stained by sweat or by rain and water, and are not shrinked or wrinkled.
Background of the Invention
Heretofore, the conventional silk products are easily stained and bleached by sweat and water, and they are very difficult of cleaning. Accordingly in the past, a number of researches and experiments have been made to eliminate these disadvantages and to improve the properties of silk products, but the water repellency thereof is easily aged or disappeared already when they are washed four times.
The object of the present invention is therefore to eliminate such disadvantages and defects of the conventional silk products, and to provide a novel process for treating silk fabrics which can be dry- or wet-cleaned by hand or by laundry machine at option, and won't be bleached or stained by sweat or by water and rain when being worn.
Brief Description of the Drawing
Figure 1 is a schematic block diagram illustrating the process in accordance with the present invention.
Detailed Description of the Invention
The present invention will now be more particularly described with reference to the accompanying drawing.
According to the present invention, the emulsification of pure fluorine is the principal process for preparing the processing material which allows to retain the original touch of silk, and to prevent the contamination caused by printing which is regarded as the greatest point at issue in the field of the dyeing industry and considered impossible to be solved.
The process according to the present invention will be described as follows, wherein the process comprises the following two subprocesses:
Firat Subprocess:
(a) The silk fabrics are dipped in a penetrant solution containing 1 to 10% of O.W.F. using the commercially available KHL-200(KOSHANOL-2B), at a pH of from 2 to 7, at a temperature of from 30"C to 500C, for a period of time of from 2 to 5 secs; and then
(b) Said fabrics are treated with the water repellent solution containing 2 to 7% of SKG-620 and 1.0 to 2.0% of KR-58, both commercially available, at a temperature of from 20"C to 40"C, for a period of time of from 2 to 7 secs.
Second Subprocess:
(1) Prior to printing, said silk fabrics are subjected to tempering in a steam of 1600C-2000C, and then subjected to the processes of printing and soaping;
(2) Soon after going through the penetrant solution containing 1%-10% of KHL-200 KOSHA
NOL-2B O.W.F., at a pH of from 2 to 7, at a temperature of from 30"C to 50"C, by dipping, for a period of time of 2-5 secs, at the pick-up ratio of 7-8%, said silk fabrics are completely dried at a temperature of 60"C:: (3) Said dried silk fabrics are again passed through the water repellent solution containing 2-7% of SKG-620 and 10-20% of KR-58, at a temperature of 20-40"C, and then passed again through a solution containing 1-10% of KHL-200 (KOSHANOL-28) O.W.F. at a pH of 2-7, at a temperature of 30"C-50"C, and them completely dried at a temperature of 70"C; (4) After going through the above processes, said silk fabrics are subjected to tentering at a temperature of 150 C-200 C, for a period of time of 80-110 secs; and then
(5) Said silk fabrics are subjected to tempering and completely dried at a temperature of from 50"C to 15000 to complete the processes.
As mentioned in above Second Subprocess, after the completion of the printing and soaping processes, the principal process is conducted wherein said silk fabrics are passed through the
KOSHANOL-28 solution (under the conditions of (a) of First Subprocess), and then passed through a mangle (pick-up rate: 70-100%, and immediately thereafter dried completely at a temperature of 70"C.
Said dried silk fabrics are passed again through a solution of (b) of First Subprocess, and then dried at a temperature of 70"C, and subjected to tentering for a period of time of from 30 secs to 2 mins, by heating at a temperature of from 16000 to 2000C.
Referring to the accompanying drawing, the above processes are explained as follows: Step A comprises (a) and (b) of the First Subprocess, and Step B comprises drying of the silk fabrics at a temperature of 70"C, for a period of time of 2-7 secs and collecting said silk fabrics into a container of Step B'. Thereafter in Step C, said silk fabrics are subjected to tentering at a temperature of from 150"C to 200 C, for a period of time of from 30 secs to 2 mins, and then dried to finished products in Step D.
To summarize, the process according to the present invention may be represented as follows: A--B--B'--A--B--B'--C--D=Perfection.
Through the above process in accordance with the present invention, said silk fabrics will obtain excellent features of anti-contamination, water repellency, wrinklessness, unshrinkableness, outstanding silky touch, and remarkable durabilities such as fastness of color, to light, and to washing which have long been weakest points of the conventional silk products.
Said silk fabrics treated in accordance with the present invention have been tested by the
Korea textile Inspection Center, and the test results are as follows: Certificare of Inspection
The following three samples A, B, and C of silk fabrics treated by applying the above process according to the present invention were tested by the Korea Textile Inspection Center:

According to the above test results, it is confirmed that the properties of shrinkage, fastness of color, and water repellency have been remarkably improved which were the unsolved problems peculiar to the conventional 100 per cent silk fabrics.
The aforementioned test was conducted by the Korea Textile Inspection Center.
Since it has been considered impossible in the field of textile industry throughout the world to wet-clean the 100 per cent silk fabrics, there hasn't been provided a test standard therefor, like other textile fabrics, therefore the silk fabrics processed according to the present invention were wet-cleaned and tested under the following conditions in the inventor's laboratory.

As clearly described above, the present invention provides an effective process for treating silk fabrics to impart thereto an excellent water repellency, a good air permeability, and a remarkable fastness to washing, and to retain the unique touch essential to the 100 per cent silk, and to allow the mass production of such silk products with low production cost.
