Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a twisted yarn containing down, small feathers and/or feathers, and a method for producing the same.

Twisted yarns (including plied yarns) are manufactured from various natural or synthetic materials;
Furthermore, it is widely used as interior yarn for wall cloths, carpets, etc.

On the other hand, feathers, feathers, and/or feathers (hereinafter referred to as feathers) are used as heat insulating materials or cushioning materials for futons, cushions, and even cold-weather clothing. Such feathers are mainly obtained from waterfowl, and are superior in heat retention, flexibility, resilience, light weight, etc., compared to other natural or synthetic materials.

However, although feathers and the like have many excellent properties as a material, they have a property that exists independently of each other and have no relation to each other, so it is difficult to utilize them. The scope of use is limited to heat insulating materials and cushioning materials covered with fabrics, leather, etc. in futons, cold-weather clothing, etc., and is significantly narrower than the scope of use of twisted yarns as described above.

The present invention relates feathers, etc. that exist separately, and provides a twisted yarn containing the feathers, etc., and a method for manufacturing the same, and aims to widely utilize feathers, etc., which have excellent characteristics as a material. be.

Hereinafter, the configuration of the present invention will be explained in detail based on the drawings.

FIG. 1 is a schematic diagram illustrating a feather used in the present invention, and FIG. 2 is a schematic diagram illustrating a small feather. These feathers and feathers obtained mainly from waterfowl have been conventionally used in feather comforters and the like. In addition to this, a blade can also be used in the present invention, but since this blade is relatively large and has a particularly hard and strong separate shaft, it is preferable to use the blade with the separate shaft removed.

These feathers, etc., are of a nature that exists in separate pieces, completely unrelated to each other. Therefore, as in conventional feather comforters, products in which these are blown into bag-like fabrics,
Alternatively, these can be used in cases where they are covered with fabric and sewn from above and below, but these cannot be twisted as they are. Figure 3 is a schematic side view showing one embodiment of the present invention. 4 is a schematic cross-sectional view thereof, FIG. 5 is a schematic side view showing another embodiment of the present invention, and FIG. 6 is a schematic cross-sectional view thereof. The twisted yarn 1.2 according to the present invention is made of feathers etc. 3 a N 3 b -, 4
It is made by twisting long fibers 5a, 5b, 6a, and 6b together with long fibers 5a, 5b, 6a, and 6b, and there are two types of properties as shown in the figure, depending on the manufacturing method. In the twisted yarn 1 illustrated in FIGS. 3 and 4, feathers etc. 3a and 3b exist almost uniformly from the outside to the inside together with the long fibers 5a and 5b, and as illustrated in FIGS. 5 and 6. The twisted yarn 2 has feathers 4λ, 4b concentrated on the outside, protruding from the surface in large numbers, and almost no feathers 4a, 4'b inside. When feathers, etc. are twisted together with long fibers, the feathers, etc. are intertwined with or rolled into the long fibers, making it appear as if the feathers, etc. are fixed.

The types of long fibers used in the present invention may be extremely common fibers, such as animal fibers such as wool, angora, and silk, vegetable fibers such as hemp and cotton, and various synthetic fibers or recycled fibers. . These long fibers preferably have an average length of 15 mm or more.

This is because it is easy to manufacture the twisted yarn, and it is possible to obtain a twisted yarn in which the feathers and the like are more firmly fixed.

In the present invention, the preferred blending ratio of long fibers to feathers, etc. is 70 to 30 parts for the former and 30 parts for the latter in terms of weight.
The range is from 0 to 70. If necessary, an adhesive medium can also be used in order to more firmly bind the feathers and the like to the long fibers. Such adhesive media include suitable commercially available adhesives, water, separately formed sheets of long fibers, and even low melting point synthetic fibers. For example, this kind of low melting point synthetic fibers all have melting points of 130 to 1
There are Melty (trade name, polyester type, manufactured by Unitika Co., Ltd.) and ES (trade name, polypropylene type, manufactured by Chisso Corporation), which have a temperature of 40°C. When using adhesives or low-melting synthetic fibers as adhesive media, the hardness and strength of the resulting twisted yarn can be adjusted depending on the amount used, but usually in terms of weight,
The content is preferably 5 to 10% of the long fibers. At this time, if a heat-melting type adhesive or a low-melting point synthetic fiber is used, heat treatment is performed at an appropriate stage in the production of the twisted yarn.

FIG. 7 is a system diagram illustrating the manufacturing procedure of twisted yarn according to the present invention. A loose soft mass 11 of long fibers is crushed by a fiber opening machine 12, and then subjected to a carding machine 13 to form a thin sheet-like body 14. Then, on this thin layer sheet material 14, feathers etc.
5 and water 16 as an adhesive medium are uniformly sprinkled thereon, a slight pressing treatment is performed if necessary, and the material is subjected to a condenser, where a shingle 17 cut to an appropriate width is obtained. Finally, Shino 17
is subjected to a twisting process and twisted to produce a single twisted yarn 18. If necessary, it is optional to combine and twist several of the single yarns, to use a foreign yarn when combining and twisting, or to use other fibers during this combining and twisting. The twisted yarn thus produced has a form as illustrated in FIGS. 5 and 6 above.

FIG. 8 is a system diagram illustrating another manufacturing procedure for the twisted yarn according to the present invention. A loose soft mass 21 of long fibers is crushed by a fiber opening machine 22, and feathers etc. 25 are mixed therein. Next, the mixture is passed through a carding machine 23 to form a thin sheet.

Then, this thin-layer sheet-like material is subjected to a condenser to obtain shinoki cut into appropriate widths. Thereafter, as in the case of FIG. 7, twisted yarns are manufactured and optionally combined and twisted as necessary. The twisted yarn thus produced has a form as illustrated in FIGS. 3 and 4 described above.

In the production of the twisted yarn according to the present invention, the blending ratio of long fibers and feathers is usually the same as described above, the thickness of the thin sheet is about 0.5 to 3, and the width of the wire is It is about 9-20u+. These are changed as appropriate depending on the use of the twisted yarn to be manufactured. Further, in the case of FIG. 7, water used as an adhesive medium is one of the preferred examples. Once the thread has been obtained, it is no longer twisted, and the feathers, etc., become as if they were fixed to the twisted thread. Therefore, the adhesive medium must be used to attach the feathers, etc. to the thin sheet of long fibers at a stage before the production of Shino so that they do not come off easily, and it must be used separately for the twisted yarn to be produced. It is better to have something that does not affect the environment. It is also suitable to use a separately formed thin sheet of long fibers as the adhesive medium, but in this case, there is no need to sprinkle water 16, and feathers etc. 15 are uniformly spread on the thin sheet 14. After the spraying, a thin sheet of long fibers formed separately in the same manner is covered from above, and the two thin sheets with feathers etc. interposed are slightly suppressed from above and below. , and then applying this to a capacitor in the same manner as in the case of FIG. 7 described above.

In the case of FIG. 7 or 8, when low-melting synthetic fibers are used, heat treatment is performed at some stage after the fibers have reached a form that can be used in a condenser.

For example, in the case of Fig. 7, low-melting synthetic fibers are used as the adhesive medium, feathers, etc. are uniformly scattered on a thin sheet of long fibers mixed with the low-melting synthetic fibers, and this is subjected to heat suppression treatment. and apply it to the condenser. For example, in the case of FIG. 8, a thin sheet is formed from a mixture of long fibers, feathers, etc., and low-melting point synthetic fibers, and this is heated and pressed to be used in a condenser.

According to the present invention described above, feathers, etc., which are present separately, are tied together with long fibers and twisted into a yarn, thereby making it possible to widely utilize feathers, etc., which have excellent properties as a material.

Next, examples will be given. The feathers used in each example were washed, sterilized, and insect-proofed as is commonly done for feathers used in down comforters. Targeted at dry foods.

Example 1 A loose soft lump of long wool fibers having an average length of 20 yn or more was kneaded using a fiber opening machine, and a thin layer sheet having a thickness of 2 mm was formed using a carding machine. Waterfowl feathers were uniformly sprinkled on this thin sheet-like material so as to have a ratio of 50% by weight to the long fibers, and water was further uniformly sprinkled over the entire surface. Then, this was cut into long pieces with a width of 20 mm using a condenser to obtain a thread, and the thread was twisted in a twisting process to produce a twisted yarn (single yarn). The produced twisted yarn had a large number of feathers protruding from its outer surface9, and the feathers were in the form of being wound around long fibers.

Example 2 A loose soft lump of long hemp fibers with an average length of 30 mm or more is crushed using a fiber opening machine, and Melty (trade name, polyester type, Unitika M), a low melting point synthetic fiber, is applied to the long fibers. The mixture was mixed by 7 weights, and two thin sheets having a thickness of about 1 inch were formed from this mixture using a carding machine. A mixture of waterfowl feathers and small feathers is uniformly spread on one thin sheet so that each sheet has a ratio of 60% by weight to the long fibers of the waterfowl, and another thin sheet is spread from above. It covers the body. The laminated product was then passed between a pair of heating suppressing rollers at about 120° C., and then cut into long pieces each having a width of 10 mmO using a condenser to obtain a shingle. This yarn was twisted 9 times in a twisting process to form a single yarn, and three of the single yarns were combined and twisted to produce a twisted yarn. The produced twisted yarn had some feathers and feathers protruding from the outer surface, and the feathers and feathers were often entangled with the long fibers.

Example 3 A loose soft mass of nylon long fibers having an average length of 25 m or more was crushed using a fiber opening machine, and waterfowl feathers were mixed therein at a weight ratio of 40 to the long fibers. This mixture was then formed into a thin sheet with a thickness of 3 mm using a carding machine. Next, this is cut into long pieces with a width of 12 mm using a condenser to obtain a sash, which is twisted in a twisting process to make a single yarn, and the single yarn prepared in 41J and acetate are added to this single yarn. A twisted yarn was produced by combining and twisting the single yarn. The produced twisted yarn had almost no feathers protruding from its outer surface, and the feathers were almost uniformly intertwined with long fibers throughout the interior.
