Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a method for manufacturing gold and silver thread using a paper manufacturing method.

Prior Art In general, flat foil threads and twisted gold and silver threads are known as gold and silver threads. The former is made by cutting a foil sheet made of a laminate of polyester film, paper, etc. and gold and silver thin film into a certain width, and the latter is made by winding the flat foil thread around a core thread or entwining thin threads around the flat foil thread. It was formed by All of these utilize the properties of the foil sheet as they are, and have a regular metallic luster and are rigid in appearance and texture.
There are also limits to the methods and uses of weaving and knitting in combination with other fibers.

In addition, in another technical field, as a manufacturing method for special paper, vacuum-deposited Mylar film, metal powder-coated paper, etc. are cut or crushed into arbitrary sizes to form ribbon-like fragments, which are then used to prepare paper stock. It is also known to make paper by dispersing metal particles in a beater, etc., to obtain patterned paper containing metal strips, but such paper is not practical as a paper quality, and also lacks general-purpose value in terms of physical properties. As such, it has not been put into practical use industrially (see Japanese Patent Application Laid-Open No. 1302-1982).

OBJECTS OF THE INVENTION The object of the present invention is to provide a method for producing gold and silver threads with good texture using staple fibers.

Structure of the Invention The method of the present invention is characterized in that short fibrous foil yarns are mixed into a papermaking solution, paper is made, the resulting paper is cut into yarns, and the yarns are further twisted.

Here, short fibrous foil yarn refers to, for example, regular flat foil yarn or synthetic fiber yarn electrolessly plated and cut into short lengths, such as the one disclosed in JP-A No. 58-31134. Any fibrous foil yarn can be used effectively.

Next, the term "papermaking liquid" refers to a liquid containing papermaking raw materials, and is usually an aqueous dispersion containing a small amount of size material, the main component of which is cellulose fibers. It is preferable that the main component is a fiber selected from the group consisting of Japanese mulberry, mulberry, gampi, and hemp, and depending on the use, it may also contain other types of fibers such as rayon, silk, and wool.

The mixing ratio of the short fibrous foil yarns to the fibers contained in the papermaking liquid is not particularly limited, but the weight ratio is 2 to 2.
It is preferably about 70%.

The paper making method may be the same as that for manufacturing ordinary Japanese paper, and the thickness of the paper obtained can be arbitrarily selected depending on the purpose. In general, paper with a weight of 13 to 60 g/ ^m2 can be used, but thin paper with a weight of 13 to 20 g/ ^m2 has excellent metallic luster even with a small amount of foil thread content (2 to 30%).
preferable.

In the present invention, the paper produced by mixing short fibrous foil threads in this manner is cut into threads to produce the desired gold and silver threads, but prior to cutting,
Additional treatments such as coloring the paper or forming a protective film by resin coating or film bonding may be performed. Pasting films on both sides of paper, or pasting papers together around frills, can also be effectively used to obtain strong gold and silver threads.

In the present invention, a flat thread having an elegant metallic luster can be obtained by cutting. This yarn is made of moderately entangled fibers, making it flexible and strong, so it can be used as is for weaving and knitting.
Furthermore, in the present invention, since the yarn thus obtained is twisted, it is possible to obtain a product that is very easy to use and has an attractive taste.

Example 1 A silver layer was formed on one side of a polyester film (4μ thick) by a transfer method, a similar polyester film was pasted on this silver layer, and the obtained silver sheet was cut into threads with a width of 100μ. Then, the yarn was cut into short fibers with a length of 30 mm. This silver short fiber was mixed at a ratio of 2% into a paper making solution containing 10% of Mitsumata fibers, and paper was made to obtain Japanese paper with a galaxy-like appearance. This Japanese paper was further piece-colored in a light pink color, a light saxophone color, and a light horizontal green color, cut into threads with a width of 1 mm, and twisted at 700 turns/m to obtain twisted thread A.

Separately, a sheet with a width of 0.3 μm was made by pasting polyester film (4μ thick) on both the front and back sides of the above Japanese paper.
The flat thread B was obtained by cutting into threads of mm. Flat yarn B is used as warp yarn, twisted yarn A is used as weft yarn, and each cotton yarn is 80/
By weaving the material in an alternating manner with 2, it was possible to obtain a woven fabric with an innovative design that was breathable and had a good texture. The woven fabric was useful as a light weight clothing fabric.

Example 2 Polyester fibers 30D/6f were chemically plated with Ni to obtain fibers with excellent metallic luster. Next, this fiber is cut into 20 mm pieces to form short fibers, and the short fibers are mixed at a ratio of 5% into a paper making solution containing 0.5% size agent and 10% Mitsumata fibers to make paper, and the resulting paper is made into 1 mm
After cutting into threads of different widths, the threads were twisted to obtain twisted thread C.

Twisted yarn C was organized and woven to have a density of 25 to 30 threads/cm in both warp and weft to obtain a strong woven fabric. Furthermore, when this woven fabric was immersed and stirred in lukewarm water (50-60℃) for 3 hours, some of the paper fibers were washed away.
It became a soft, feather-like cloth that shone silver. Dyed black, it could be effectively used for formal clothing.

Effects of the Invention In the present invention, the conventional foil yarn, which is rigid and has a monotonous metallic luster, is made into short fibers, mixed with other fibers to make paper, and cut into threads, which are then twisted and made into gold. In order to obtain silver thread, it is possible to obtain gold and silver thread with a good texture and a change in metallic luster. Furthermore, the gold and silver thread obtained by the present invention is made by twisting short foil thread fibers with appropriate strength and intertwined with cellulose fibers, so it is very easy to handle and can be woven or knitted into clothing materials. Can be used directly. Dyeing after weaving or knitting is also possible.
