Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to artificial fur, and more particularly to artificial fur with significantly improved appearance and feel of raised hair.

Natural fur, such as mink, foxtail, raccoon, and sable, has excellent properties such as appearance, luster, and texture, and is therefore recognized as a particularly high-quality material for making high-end fashion clothing. In the past, various technical proposals and research have been conducted in an attempt to create artificial fur with high quality. As a relatively advanced product in the field of artificial fur, for example,
No. 116670, Japanese Patent Application Laid-open No. 55-137'244.

A new technique has been disclosed in Japanese Patent Application Laid-Open No. 56-58067 and the like. However, even with these technologies, it is difficult to artificially achieve the characteristics of natural fur in appearance, texture, etc., and the current situation is that it is still a long way off.

In view of the above points, the present inventors have made several effective proposals so far, but the main purpose of the present invention is to increase the nap density of the tipped fibers with a sharp tip. The purpose of the present invention is to provide artificial fur that exhibits the appearance of high-grade natural fur by adding a striped pattern to the surface of the raised fur.

That is, the present invention provides an artificial fur made of a vertical pile fabric, in which the pile threads are made up of comb fibers and cotton wool fibers and are fixed to the ground structure, and exist as fiber bundles within the ground structure. In the section, the constituent single fibers are opened and raised, and the pile fibers constituting the pile yarn have sharpened tips, and the nap density of the pile yarn is 600 pieces/pile. This artificial fur is characterized by having a striped pattern on the pile surface at lengths above 1'. More preferably, the striped pattern is based on a difference in color tone of the curly fibers. Causes due to differences in the nap length of the curly fibers, differences in apparent thickness or denier of the curly fibers, differences in the nap density of the curly fibers, differences in color tone of the cotton wool fibers, cotton wool This is due to the difference in the nap density of the conditioned fibers.

The present invention will be described in detail below with reference to nine drawings and the like.

In this invention, artificial fur consists of a base fabric and napped fibers that are densely raised from the base fabric, and the production of the artificial fur is preferably carried out using a conventionally known single or double pile loom. It is obtained by doing.

In addition, in a fast pile structure with a conventional weave density of 50 vertical piles/inch or less, the pile yarn density is 50 yarns/inch or less.
The limit is about 0 lines/square inch.

At this time, even if a pile yarn made by blending 40 pieces of 40a combed fibers with a thread count of 108 is used to obtain a high pile fabric, the napped density of the combed fibers is approximately 500 pieces/an''. Yes, the nap density of the present invention fiber is 600 fibers/a2
In order to obtain the above high density, use thin warp yarn and make pile yarn with fine yarn count of 10s or more.
This can be achieved by weaving yarns made by blending about 40 threads of about d with a warp density of 60 threads/inch or more.

More preferably, by weaving at a vertical density of 70 fibers/inch or more, a nap density of 800 fibers/(!'n2 or more) can be obtained.

FIG. 1 is a cross-sectional view showing a model of the artificial fur of the present invention, which expresses a striped pattern by the difference in the length of the hair-like fibers raised from the ground tissue. In the figure, the raised part 1 consists of pile-like fibers 6, 4 and cotton-like fibers 5, and the root part is fixed in the base structure 2. The fixation is performed by a fabric and/or a backing material. Pile part 1
In the process, the pile fibers are opened to create pile-like fibers 6.
4 has a relatively longer nap length than the fluffy fiber 5, has a sharpened tip, and has relatively straightness. Also at the root.

The pile yarn has a fiber eastern part and is fixed by the base structure 2.

The raised portion 1 is made of two or more types of pile fibers.

The nap-like fibers of the raised part 1 that are raised from the part of the ground texture A have a relatively long nap length compared to the raised fibers of the raised part 1 that are raised from the part of the ground texture B. Further, the nap length of the fluff-like fibers 5 may be the same length as the nap part that is raised from the base texture A part and the raised part that is raised from the base texture B part.

The width at which the lines can be distinguished between part A, which is made up of piling fibers with a relatively long nap length, and B, which is made up of piling fibers with a relatively short nap length, differs depending on the nap density of the pile yarn. Identification is possible if 10 or more root binding parts of the pile yarn belonging to parts A and B are present in succession and alternately, but in order to clearly appear as streaks on the nape surface, the width must be 20 mm or more. Preferably, they are arranged alternately.

FIG. 2 is a cross-sectional view of the artificial fur model of the present invention, which expresses a striped pattern by the difference in the density of the raised hairs of the hair-like fibers raised from the ground tissue. In the figure, the raised part 1 is made up of a pile-like fiber 6.7 and a cotton-hair-like fiber 5. The root part is fixed in the ground structure 2. The pile fibers are opened in the raised part 1, and the pile fibers 6 and 7 have a relatively longer pile length than the cotton pile fibers 5, have sharpened tips, and are relatively straight. It has a sexual nature. Further, at the root part, the pile yarn has an eastern part of the fibers, and is fixed by the base structure 2.

The raised portion 1 is made of two or more types of pile fibers.

The nap-like fibers of the raised part 1 which are raised from the part of the ground texture C have a relatively thick denier compared to the raised fibers of the raised part 1 which are raised from the part of the ground texture B. Further, the denier of the fluff-like fibers 5 may be the same thickness for the raised part that is raised from the part of the ground texture C and the raised part that is raised from the part of the ground texture.

Part 0 is made of relatively thick denier hair-like fibers,
The width at which the line can be distinguished from the D section, which is made of relatively thin denier piling-like fibers, varies depending on the nap density of the pile yarn, but there are at least 10 root binding parts of the pile yarns belonging to the 0 section and D section. If they are consecutive and alternate, they can be identified, but in order to clearly appear as streaks on the surface of the nape, it is preferable to arrange them alternately with a width of 20 mm or more.

Above are the striped patterns due to the difference in the length of the raised fibers,
Although we have explained the striped pattern due to the difference in denier of the combed fibers, we can create a striped pattern by using the same method as the difference in the apparent thickness of the combed fibers.

Striped patterns due to the difference in color tone of the combed fibers, striped patterns due to the difference in color tone of the cotton woven fibers (these color differences are realized by using pattern yarn), stripes due to the difference in the napped density of the combed fibers. A striped pattern can be obtained due to the difference in the nap density of the cotton fibers.

Furthermore, by appropriately combining each stripe pattern,
It is also possible to obtain a more distinct striped pattern.

Hereinafter, the present invention will be specifically explained with reference to Examples.
