[ Precise explanation of the invention ] )

[ The field of the industrial application ]

This invention is aimed to producing the paper mulberry yarn ) from the cellulose and it's producing method.

[ The conventional art ]

1 ₎ The origin of the conventional art of making the yarn from the paper mulberry cellulose could be traced back to very long ago, as we might guess by the fact that the paper lace art, an korean traditional one took a place of it, though the accurate ₎ times not known well. As such an art is succeeded to nowadays, the gist of this art is composed of manufacturing the korean paper, a sort of the paper mulberry paper first, splitting in the narrow band, twisting and linking to the yarn of a very thick ₎ diameter in the old days and the thread of a fine denier from 2mm narrow paper strip twisted in the latest.

[ The task to be accomplished with the invention ] )

The conventional method of manufacturing the paper mulberry yarn as above costs very much high, the complication of the

) process let alone, since in the old way the basic paper should be prepared in the first place and the yarn is spun from the material paper in the next. Such an obstacle has worked an decisive factor of the limitation to the diffusion of the korean

1₆ ) paper yarns, even though they have many a functional merit and the possibility of the evolvement. The attempt to solve these tasks eventually arrives at the trial of finding out of the way of spinning the yarn directly from the paper mulberry cellulose as

17 ) the other natural fibers such as the cotton and the rayon etc.

[ The means to solve the task by ]

-^_{g )} The means to solve the task by lay just at the application of the ways of spinning the yarn from the existing natural fibers. However, as the paper mulberry cellulose has the property to become hard at the ambient temperature and also the yarn is

_{19 )} too much rigid for the clothes, the proper processing method for the paper mulberry yarn to complement the above defect is rightly adopted.

_{2Q )} [ The composite of the invention ]

This invention is precisely explained as follows, with the reference to the drawing 1 and the drawing 2 affixed.

21 )

If the basic composition of this invention is examined at the first, we can say the producing method for the paper mulberry yarn by it has the respective characteristic to comprise

22 ) at the manufacture of the yarn in the dry spinning style,

23 ) the process of steam boiling the stalks of the paper mulberry in the pressure tank at the high temperature and tension for a certain duration (10);

) the process of peeling off the embark and separating the bast from the stalks pulpily softened through the above process (10) (20);

5 ) the process of obtaining the paper mulberry cellulose from the bast separated through the above process (20) and boiled in the solution over 130°C diluted with the fiber treatment softner etc.

(30); 6 ) the process of freezing and ambient air drying of the cellulose obtained through the above process (30) (40);

7 ) the process of cutting and splitting the wad of the cellulose dried through the above process (40) into a certain breadth and length (50);

₈ ) the process of spinning the yarn from the cellulose cut and split through the above process (50) and put in the appropriate spinning machine (60); and

g ₎ at the manufacture of the yarn in the wet spinning style,

the process of steam boiling the stalks of the paper mulberry in the pressure tank at the high temperature and tension for a _{Q )} certain duration (10');

the process of peeling off the embark and separating the bast

1 ) from the stalks pulpily softened through the above process (10')

(200;

the process of obtaining the pure paper mulberry cellulose ) from the bast separated through the above process (20') and boiled in the solution over 130°C of the vacuum hyper pressure ( over 3 M/T ) tank during a certain time (30') I

) the process of cutting and crushing the cellulose obtained through the above process (30') to bits and pieces (40');

the process of making the cellulose porridge with mixing the ₎ cellulose cut and crushed through the above process (40'), the fiber treating softner and the appropriate quantity of the cellulose adhesive agent and with rotating the blended in water at the high speed on the blending machine (50'); ) the process of spinning the raw thread spun through the minute pores of the various adjustable caliber of the spinning machine which contains the cellulose porridge made through the above \ process (50') and lets the fine filaments emit out by compressing (60');

the process of drying the raw paper mulberry yarn spun : through the above process (60') with the heated air (70');

the process of winding the paper mulberry yarn dried through the above process (70') on the bobbin (80'). )

[ The desirable example of implementation ]

) The best mode for carrying out this invention is precisely explained as follows, with the reference to the drawing 1 and the drawing 2 affixed.

⁾ The best possible stock of the paper mulberry plant for the make of the yarn is the budding stalk of 1 year growth, for it is supple with the moist and much cellulose. After this stock is boiled for about 10 hours (10 and 10'), the bark becomes pulpily ) soft and easy to peel off. This bark, called the black one is composed of the bast fiber. In reality, the black bark well dried is traded in the unit of the metric ton and we can buy it to put into the following processes. )

After the black bark is steam boiled in the pressure tank at the high temperature and tension for 2~3 hours, it gets pulpily soft as the stock does as the above and we can easily peel off the ) outer bark to separate the inner bast apart (20 and 20'). This inner bast, called the white bast is the material for the paper mulberry cellulose.

) As the bast fiber of the paper mulberry is constituted of a little saccharin, the ash, the lignin and the holocellulose and the most effective component among these ones is the holocellulose, the aim of this process is to procure as much pure holocellulose ) as possible. The holocellulose content of the black bark is about 67.5%, approximately % and this content is said to improve to about 75.36%, approximately f at the state of the white bast.

₎ When we let this white bast, from which the sugar, the ash and the grease etc. except the fibroid material is taken away in the solution of the chemicals such as the lye, the soda ash, the

) caustic soda and the sodium sulphate etc. of 2.5 multiple around at the weight standard of the water, ret in the flowing water below 10⁰C degree in the sunny light for over 2 hours, we can get the sun bleached and a bit alkaline cellulose of the fairer ₈ ) quality. Especially while the white bast is put in the running water, the lignin, the minute fibers which stick between the holocellulose, the long filaments and hold them together to make the paper mulberry cellulose hard is washed away to the effect

4_{9 )} that it accelerates the softening of the cellulose. Besides, the work of selecting the motes, the bark debris, the bruises, the sleeping buds and the trivial sand particles etc. off could be included into this pre treatment process.

50 )

After the bast pre treated as above is boiled in the hot water solution over 130 °C diluted with the fiber processing softner at the rate of 2~3% made from the natural glycerine etc. during a c-t \ certain time (30 and 30'), we can get the paper mulberry cellulose. With freezing and drying it at the ambient climate (40) and with cutting and splitting it in a certain breadth and length (50), the wad of the raw cellulose, so to speak 'the raw cotton

_{52 )} just before the yarn spinning' is born. The following processes of making the sliver from the raw cellulose, of roving and fine spinning and of winding the paper mulberry yarn up are very similar to the corresponding processes of the cotton spinning.

53 )

On the other hand, as we mix the raw cellulose particles made from the cellulose acquired though the procure process (30 and 30') and cut and crushed to bits and pieces through the segmenting process (40'), with the water (4 times of the whole 54 ) ingredient ) solution of the additive, 2~3 % of the fiber treating softner of the natural glycerine etc. and the appropriate amount

55 ) of the paper mulberry cellulose adhesive such as the starch out of the abelmoskC Hibiscus manihot, Linne) root or the mucilage from the larch etc. and rotate the above blend at the high speed in the mixing machine, the paper mulberry cellulose porridge is ) formed (50').

In the next, as we put the cellulose porridge into the spinning pot and adjust the viscosity of it, the raw thread is squeezed ₎ out of the minute pores, a certain diameter of which can be regulated depending on the needs for the usage of the yarn (600.

₎ On drying the spun raw thread in the heated wind (70') and winding up on the bobbin (80'), we can get the completed paper mulberry yarn at the last. The spinning process of the viscose rayon etc. served as a good reference. )

[ The effect of the invention ]

Through the above processes, the new and environment _j compatible material, the paper mulberry yarn is developed from the paper mulberry cellulose which has been used only for the paper, the non woven fabric raw material for the late twenty centuries. This new yarn is expected to contribute greatly to the clothing life of the human kind abreast with the other ones ) of the natural fiber which men has developed, for instance the linen yarn, the woolen yarn, the cotton yarn and the silk yarn etc. )
