Abstract

PURPOSE:To provide a cut pile fabric reduced in the falling of the piles on the pile surface thereof and capable of retaining an excellent appearance by employing six-lobar cross section polyester fibers and/or polyamide fibers having a specific single filament fineness as the pile fibers. CONSTITUTION:Polyester fibers and/or polyamide fibers each having a six-lobar shape cross section and a single filament fineness of 1.0-5.0 denier are employed as pile fibers to provide a cut pile fabric whose piles have appropriate rigities and repulsive forces.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to cut pile fabrics, and mainly relates to cut pile fabrics used for seats in automobiles, trains, buses, etc.

[Conventional technology]

Traditionally, cut pile fabrics made of moquette fabrics and knitted fabrics have been widely used for seats in cars, trains, buses, etc. Natural fibers such as wool and animal hair, and synthetic fibers such as nylon and polyester are generally used, and the pile fabrics made of these materials have a good feel and a luxurious feel, but polyester fibers in particular are It is widely used because it has excellent light resistance and abrasion resistance. Also, especially the feel (
To do. Polyester fibers with a flat cross section are used, but the pile of fibers with this cross section tends to cause the pile hair to fall during use, and the area where the pile falls is due to the fact that the side part of the fiber is exposed to reflected light. There was a tendency for the image to look whitish and blurry. Also. A method was used to reduce the white blur by making the cross section a wavy cross section as shown in Figure 3 to diffusely reflect the opposite light from the side, but during use of the sheet, the waist of the wavy cross section cracked vertically and formed fibrils. This has the disadvantage that it causes the hair to curl and fall down.

[Problems to be Solved by the Invention] The present invention maintains the good feel of the cut pile fabric as described above, and has a constantly uniform appearance with less hair falling and white blur caused by the shape of the cross section. The purpose is to provide cut pile fabrics of good quality. [Means for Solving the Problems and Effects] The present invention has been made as a result of intensive research to achieve the above object, and is directed to the production of cut pile fabrics made of moquette fabrics or knitted fabrics. A solution was achieved by using pile fibers that are polyester fibers and/or polyamide fibers that have a six-lobed cross section and a single filament fineness of 1.0 denier or more and 5.0 denier or less. It is something. To explain the present invention in more detail, it is an essential requirement that the cross section of the pile fibers constituting the cut pile fabric be in a six-lobed shape, and by the melt spinning method, a spinneret having a nozzle shape as shown in Fig. 2 is used. By spinning the fibers, a fiber having a six-lobed cross section as shown in FIG. 1 is obtained. Fibers with a six-lobed cross section make the pile extremely difficult to fall over, and since there are vertical grooves on the sides of the pile, these become finely angled surfaces that diffusely reflect the light that hits the sides of the pile, changing the overall appearance of the pile. This has a special effect in that the sense of white blur is slightly reduced. In this case, the two objects of the present invention can be achieved by using pile yarn containing 50% or more of fibers with a hexagonal cross section. In addition, the fibers that make up the pile are polyester fibers (
Polyethylene terephthalate fibers, copolymerized polyethylene terephthalate fibers containing isophthalic acid, paraoxybenzoic acid, sulfoisophthalic acid, or butylene glycol as copolymer components) and polyamide fibers (nylon-4 fibers, nylon-6 fibers, nylon-66 fibers, nylon -610 fiber or nylon-11 fiber), etc.
The fiber yarn may be used alone, or may be used in common to knit a mixed fiber into stripes, patterns, etc. to change the texture or coloring. What is required next to manufacture the above fibers? These are the titanium oxide content and fiber thickness. The titanium oxide content must be 0.1% by weight or more and 1.0% by weight or less, and the fiber thickness is preferably 1.0 denier or more and 5.0 denier or less. If it is less than 1.0 denier, the fibers are too soft and tend to fall, while if it exceeds 5.0 denier, the pile fabric becomes rough and hard.2 A pile fabric with a suitable texture as obtained by the present invention. is not obtained.

【Example】

Examples of the present invention will be listed below and explained together with comparative examples. (Example) As the pile yarn, polyester fibers with a hexagonal cross section as shown in Figure 1, containing 0.3% by weight of titanium oxide, a fineness of 3 denier, and a fiber length of 51 mm were used. A spun yarn with a first twist of 14 times/S'', a final twist of 11 times/S'', and a cotton count of 22/2 was prepared, and this yarn was dyed using a boat-based polyester dyeing method. The ground yarn is a blended yarn of 20/2 cotton count and 65 parts of spun-dyed polyester and 35 parts of spun-dyed rayon, and the weaving structure has a reed density of 8.2.
The ground structure was constructed with a driving density of 5 threads/cm and a driving density of 16 threads/cm, and the above-mentioned pile yarn was used for the reed threads,
A moquette with a pile length of 2.8 wm was constructed. (Comparative Example) As a pile yarn, a cross section of polyester fiber has a flat cross section with a length: width ratio of 1:3 to 4. Fineness 3 denier, fiber length 51 without titanium oxide
A spun yarn was obtained using the dragon raw material in the same manner as in Example 1, and the yarn was dyed. A prototype moquette was made in the same manner using the ground yarn and below, and was used for comparison. The pile properties of the moquettes obtained in Example 1 and Comparative Example were
Shown in the table. Incidentally, hair fall and white blur in Table 1 were evaluated using the following methods. (1) Hair fall (degree of restoration of pile) A constant load was applied on the pile, and the degree of restoration of the pile was evaluated when the weight was removed after a certain period of time. 〇- Good restoration △・- Fair restoration The difference in gloss at that time was evaluated. ○... Items with very little difference in gloss 8 - Items with a slight difference in gloss x - Items with a large difference in gloss

[Brief explanation of the drawing]

FIG. 1 shows an example of the present invention in which the fibers have a hexalobal cross section and are used in a cut pile fabric, and FIG. FIG. 3 is an explanatory diagram showing a comparative example of a fiber having a wave-shaped cross section. As shown in Table 1, Example 1 of the present invention is a good moquette in which the degree of pile restoration against hair falling is good, and white blurring is less likely to occur.

【Effect of the invention】

The cut pile fabric of the present invention uses fibers with a hexagonal cross section as the pile yarn, so the pile has appropriate rigidity and reaction force, so the pile surface It is possible to maintain an excellent appearance even during use, with significantly less hair fall and almost no discomfort such as white blurring.
