[ Precise description of the invention ]
7 ) [ Technical field ]
This invention regarding to the manufacturing method for the non woven silk fabric, is more concretely about the mechanical produce of the non woven silk fabric with splitting of the cocoon, getting
8 ) rid of the wax composite at the high temperature and pressure, extracting of the only fibroins, the pure fabric materials, the primary forming through the beating and the completion of the shape with the adhesive agent, the Korean paper mulberry glue.
9 ) [ Background Art ]
As already known wide, the silk fabric was developed some thousands years ago and the way to acquire the silk fabric that the cocoons constructed by the silk worm are boiled, the yarn is drawn
10 ) manually or by machine from the boiled cocoons and the silk fabric is woven with the yarn and the thread is continuously inherited for thousands years.
Besides such traditional know how to get the silk fabric, it seems H ) very rare idea to try to procure practically not the woven but the non woven fabric from the cocoons, let alone the theory.
As the result of looking over the key word, "non woven silk fabric" through the automatic researching system of Korea Institute 12 ) of Patent Information under Korean Intellectual Properties Office, it becomes found that the following 2 patents had been registered. 1. Non- Woven Silk Fabric making method, of Application No. 10-1980-0000358 of Application Date of Jan. 31st 1980
The gist of this invention is regarding to the method of getting 3 ) sort of the non woven silk fabric, the alternative sheet-like cocoon instead of the normal oval one, which the silk worms that are ready to pour out the drainage of the liquid yarn after the fifth silk worm age at the 26th days around, from the birth make on the silk worm web, the vertical wall of which is not built, under the ^ ) human surveillance.
2. Non-Woven Fabric comprising ultra-fine fibre of the silk-like materials and the making method thereof, of Application No.
10-2003-7011871 of Application Date, the 9th Nov. 2003 5 )
The contents of this invention is regarding to the non woven fabric from the silk fibroin and/or the ultra fine fibre of the silk-like material being dissolved in the hexafluoroacetone hydrate or the solvent, the main component of which is the 6 ) hexafluoroacetone hydrate is electro spun and formed of the filaments.
Except the above, the other invention is "the manufacturing method of the non woven fabric hard to inflame" (the application ) no. 20-2003-0039912, the application date of Dec. 23rd, 2003), which has been applied by the inventor of this know how. The idea of the above patent is about the manufacturing method for the non woven silk fabric, which is to obtain the pure fibroin from the silk worm cocoons cut apiece, boiled at the high pressure and temperature, to 8 ) clean, wash and beat it, to dissolve it fractured and segmented again in the water, to add the adhesive glue to it, to scoop up it of the sheet shape with the wooden web wire for the Korean paper mill, to dry it and finally to get the non woven silk fabric, so to speak utterly manually. ( 19 )
[Disclosure of Invention]
As might be known in the above, this invention can be one of the most suitable way to automate the production of the non woven
( 20 ) silk fabric, being the utmost method to acquire the non woven silk fabric more effectively with lesser efforts and costs than the any other conventional ones.
The silk worm cocoon is composed of some wax, sericin part and
( 21 ) the filaments of the fibroin of the pure protein over 77%. As it were, the silk worms make the cocoon, the natural non woven fabric from their filaments fixed in its own way. Since such non woven fabric cann't be utilized to the human needs, there arises the necessity to disorganize and to reorganize it to our want. Upon
( 22 ) such basic premise, the 3 following technical tasks for this invention to achieve can be referred.
The first one is the technique of the separation of the 2 major composition of the cocoon. The way adopted by this invention to
( 23 ) this effect is to execute the process of dissolving and removing the waxen part at the water of the high degree of the temperature under the high pressure.
The second one is that of the prime forming of the separated pure
( 24 ) filaments as the base of the non woven fabric. To solve this task, we intended to apply the beating machine which has been used to handle the cotton and developed the "beating system to meet the treatment of the new material.
The third one is that of the setting of the filaments primarily ) formed through the process of the beating into the more stable tissue of the fabric. This task could be reached at last by applying the Korean paper glass glue used at the traditional Korean paper mill (the vegetable adhesive made from the roots of the Korean abelmosk). )
Upon the solve of the technical tasks as the above, we come to give the birth to the non woven silk fabric, totally different from the natural non woven silk fabric in the point of view of the shape and the components. )
[ Best Mode for Carrying Out the Invention ]
This invention is precisely explained as follows, with the reference to the drawing 1 and the drawing 2 affixed. )
If the basic composition of this invention is examined at first, we can say the producing method for the non woven silk fabric by this invention has the characteristics to include, at the manufacture of it, the process of the split of the silk worm cocoons and the ) procure of the filament materials (10);
the process of boiling of the filament material procured through the above process(lθ) in the pressure tank .at the high temperature and tension for the appropriate time and claiming of the filaments with ) the removal of the pollution and the waxen component(20); the process of washing of the filaments claimed through the above process(20) in the industrial laundry and in the flowing distilled water(30);
) the process of drying of the filaments washed through the above process (30) with the hot air (40);
the process of the 3 times, vertical and horizontal beating of the filaments dried through the above process(40)(50); ) the process of evaporating the adhesive agent in the shape of the fog onto the filaments primarily formed through the process of the beating(50), which become more stable fibrous tissue thereafter(ΘO);
) the process of drying of the non woven fabric finally formed through the process of jetting of the glue(60), with letting it pass between the hot tubes(70);
the process of ironing of the non woven fabric dried hot through ) that of the drying(70)(80);
the process of trimming of the non woven fabric ironed through that of the ironing(80)(90).
) Let us more precisely describe on this invention according to the desirable example of the conduct as follows.
The silk worm cocoons, regardless of the classifiable or not, and the other by-products of them can be used and the oval ones have ) to be cut in half, from which the larvae with the shield membranes are removed. For the next process, the pieces of the cocoons splitted into two through the above process of the cutting(lθ) is boiled in the 135°C hot water of the tanker of the 3 M/T to 3.5 M/T tension for 2 and half hours and the pure filaments, which are the collective of the ) fibroins constituted of the amino acid protein are obtained from the fragments of the cocoons through this process. As these fibroins are known to be composed of lots of fibril, the hyper ultra fine threads in the range of nano meter thickness, at which the numberless pores can be observed with the aid of the electronic ) microscope, such structure could be declared to be one of the reasons why the non woven silk fabric has the nature to be of the affinity to the surrounding environment and to be beneficial to the human body.
) After the filaments held together in the shape of the wad of the cotton wool are taken away from the boil of these cocoons, they meet the process of the washing (30), that has the two sub processes of boiling the wad of the filaments again at the 100°C hot water in the industrial laundry for 30 minutes and of letting it ) cleaned in the running water, purified like the diluted during 24 hours. The wad of the filaments, washed and cleaned through the process of the washing (30) is dried fully through the process of the drying (40) and thereafter, bears the appearance of the fibrous tissue interlocked densely. )
As the wad of the filaments is evenly spread in front of the inlet of the beating machine, the process of the beating (50) that the beating devices beat and elongate it 3 times vertically and horizontally to make the outlook of the soft cotton wool follows. ) The next important process is that of jetting of the adhesive agent(βθ), i.e., that the Korean paper glue made from the roots of the Korean abelmosk in the shape of the fog is permeated evenly onto the surface (in the case of the non woven silk fabric for the
43 ) filter or the wall paper) or the both faces (in the case of the non woven silk fabric for the padding of the garments) of the filaments sheet already formed in a certain breadth and thickness through the previous process of beating(50), while it passes the glue evaporating system and the stabilized fibrous tissue as the non
44 ) woven fabric is fixed finally.
Thereafter, through the process of the drying (70) that the non woven silk fabric almost completed through the process of the glue jetting(ΘO) is dried with going between the heated iron tubes and
45 ) through that of ironing (80) to make the appearance and the shape neat and that of the trimmingOO) to adjust the edge and the measure, the make of the non woven silk fabric is finished.
The non woven silk fabric manufactured through the above ^6 ) processes can be roughly classified 2 kinds of the one in the shape of the flat sheet and the another in the form of the sheet felt like downy with some thickness according to the way of the adhesive agent evaporation and be used for the filters, wall papers and the garments padding e.t.c, respectively according to the shape and
47 ) form.
[ Industrial Applicability ]
The human kind has got the new material which is affined to the
48 ) environment as a natural substance, beneficial to the human body, hard to inflame when set fire to and at the same time, uncomparably surpassing in the easiness of being tailored, sewed and filled between the outer fabric of the clothes and the interlining when used as the padding of the garments, compared with the similar kind of the padding material as the cotton wool, the wool, the duck down and the goose down, e.t.c.
