Precise description of the invention

Technical field

[0005] This invention is related to the manufacturing method for a non woven silk fabric and is more concretely about the mechanical production of a non woven silk fabric including the steps of splitting the cocoon, getting rid of the wax composite at the high temperature and pressure, extracting only the fibroins, the pure fabric materials, primary forming through beating and completion of the shape with the adhesive agent, the Korean paper mulberry glue.

Background Art

[0006] 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 yam is drawn manually or by machine from the boiled cocoons and the silk fabric is woven with the yam and the thread is continuously inherited for thousands years.

[0007] Besides such traditional know how to get the silk fabric, it seems a very rare idea to try to procure practically not the woven but the non woven fabric from the cocoons, let alone the theory.

[0008] KR 10-1980-0000358 (Application Date of Jan. 31 st 1980) discloses a method for producing a non woven silk fabric by using an alternative sheet-like cocoon instead of the normal oval one.

[0009] KR 10-2003-7011871 (Application Date of 9th Nov. 2003) is related to a non woven fabric made from a silk fibroin and/or a ultra fine fibre of the silk-like material, being dissolved in hexafluoroacetone hydrate or a solvent, the main component of which is the hexafluoroacetone hydrate. The non woven fabric is electro spun and formed from the silk fibroins.

[0010] CN-A-1 085614 (Publication Date of 20th Apr. 1994) discloses a non woven silk fabric, which is produced using silk as material, which is passed through degreasing, drying, opening, carding, glue spraying and settling devices.

[0011] KR 20-2003-0039912 (Application date of 23rd Dec. 2003), discloses a manufacturing method of a non woven fabric which is hard to inflame. The idea of that method is to manufacture a non woven silk fabric by the steps of:

obtaining a pure fibroin from silk worm cocoons, which are cut apiece, boiled at high pressure and temperature; cleaning, washing and beating the fibroins; dissolving the fractured and segmented fibroins again in water; adding adhesive glue to it; scooping it up in sheet shape with the wooden web wire for the Korean paper mill; drying it and finally getting the non woven silk fabric, so to speak utterly manually.

Disclosure of Invention

[0012] As might be appreciated from the above, this invention can be one of the most suitable ways to automate the production of the non woven silk fabric, being the utmost method to acquire the non woven silk fabric more effectively with lesser efforts and costs than by any other conventional method.

[0013] The silk worm cocoon is composed of some wax, sericin part and the filaments of the fibroin. The content of pure protein is 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 can not be utilized to the human needs, there arises the necessity to disorganize and to reorganize it to our want. Upon such basic premise, the three following technical tasks for this invention to achieve can be referred.

[0014] The first one is the technique of separating the two major components of the cocoon. The way adopted by this invention to this effect is to execute the process of dissolving and removing the waxen part in hot water under high pressure.

[0015] The second one is that of the prime forming of the separated pure filaments as the basis 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.

[0016] The third one is that of the setting of the non woven fabrics primarily formed by beating into the more stable tissue of the fabric. This task is 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).

[0017] Upon solving the technical tasks as mentioned 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

[0018] This invention is precisely explained as follows, with reference to enclosed drawing 1 and drawing 2.

[0019] If the basic composition of this invention is examined at first, we can say the production method for the non woven silk fabric by this invention has the characteristics to include, at the manufacture of it, the following steps:

splitting the silk worm cocoons and procuring the filament material (10);

boiling the filament material procured through the above process (10) in the pressure tank at the high temperature and pressure for the appropriate time and claiming the filaments with the removal of the pollution and the waxen component (20);

washing the filaments claimed through the above process (20) in an industrial laundry and in flowing distilled water (30);

drying the filaments washed through the above process (30) with hot air (40);

beating the filaments dried through the above process (40) three times vertically and horizontally (50);

evaporating an adhesive agent in the shape of the fog onto the non woven fabrics primarily formed by beating(50), by which the filaments become more stable fibrous tissue thereafter (60);

drying the non woven fabric finally formed by jetting the glue (60), by letting it pass between hot tubes (70);

ironing the dried non woven fabric (80);

trimming the ironed non woven fabric ironed (90).

[0020] Let us more precisely describe this invention according to the desirable example of the conduct as follows.

[0021] The silk worm cocoons, regardless if they are 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.

[0022] For the next step, the pieces of the cocoons split into two by cutting (10) are boiled in the 135°C hot water of a tanker of the 3 M/T to 3.5 M/T pressure for 2 and half hours and the pure filaments, which are the collective of the fibroins constituted of amino acid protein are obtained from the fragments of the cocoons through this process. These fibroins are known to be composed of lots of fibril, the hyper ultra fine threads in the range of nanometer thickness, at which the numberless pores can be observed with the aid of an electronic microscope. Such structure could be declared to be one of the reasons why the non woven silk fabric has the nature to be affine to the surrounding environment and to be beneficial to the human body.

[0023] After boiling the filaments held together in the shape of the wad of the cotton wool, they meet the step of washing (30), that has the two sub processes of for 30 minutes and of cleaning it in the running water, purified like the diluted during 24 hours. The washed and cleaned wad of the filaments is dried fully through the process of the drying (40) and thereafter, bears the appearance of a densely interlocked fibrous tissue.

[0024] As the wad of the filaments is evenly spread in front of the inlet of the beating machine, the beating devices beats and elongates it 3 times vertically and horizontally to make the outlook of a soft silk non woven fabric

[0025] The next important step is jetting of the adhesive agent (60), i.e., that the Korean paper glue made from the roots of the Korean abelmosk is evenly sprayed onto the surface (in the case of the non woven silk fabric for the filter or the wall paper) or both faces (in the case of the non woven silk fabric for the padding of the garments) of the non woven fabric sheet already formed in a certain breadth and thickness through the previous step of beating(50), while it passes the glue evaporating system and the stabilized fibrous tissue as the non woven fabric is fixed finally.

[0026] Whereafter, the non woven silk fabric almost completed by glue jetting (60), is dried by going between heated iron tubes (70) and by ironing (80) to make the appearance and the shape neat. After trimming (90) to adjust the edge and the measure, the make of the non woven silk fabric is finished.

[0027] The non woven silk fabric manufactured through the above steps can be roughly classified in two kinds - one is in the shape of a flat sheet and the other one is in the form of a felt-like and downy sheet with some thickness according to the way of the adhesive agent evaporation and may be used for filters, wall papers and garments padding etc., according to the shape and form, respectively.

Industrial Applicability

[0028] The human kind has got a new material which is affined to the 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 clothes and the interlining when used as padding of garments, compared with a similar kind of padding material like cotton wool, wool, duck down and the goose down, etc..
