Description

[Detailed description of the invention] The present invention has 9 deep colors and 9 high fluff density.

This relates to the production of velvet-like fabrics that are pleasant to the touch. Traditionally, raised fabrics made of piled fabrics such as velvet, corduroy, and plush fabric have been produced in two ways: one is formed from a warp velvet structure using a double velvet loom, and the other is formed from a weft velvet structure such as velveteen. Manufactured by.

In either case, a velvet-like fabric is obtained by cutting the warp or weft that constitutes the pile with a knife.

However, it takes a lot of effort to cut the yarn, especially in the case of ultrafine fiber bundles with a single filament fineness of 0.5 denier-A/or less, the stiffness of the yarn is low, and the cutting of the yarn with a velvet loom means a piling structure. Because it is difficult to form a raised fluff and the length of the fluff is uneven, velvet-like fabrics made of ultra-fine fiber yarns have not been produced to date, despite the soft feel and elegant luster characteristic of ultra-fine yarns. However, at present, velvet-like fabrics with deep colors have not yet been obtained.

The present invention was developed in view of the current situation, and has nine textures: soft to the touch and deep in color.

The purpose is to obtain a velvet-like fabric with high fluff density.

Velvet W of the present invention! The four fabrics have the following configuration.

That is, the present invention uses a filament yarn with a single filament fineness of 1 denier or more as the core thread of the molle yarn, and uses ultrafine fibers with a single filament fineness of 0.5 denier or less in the covering part. Weaving using denier mall yarn as the weft and either or both of false twisted synthetic fiber yarn and composite crimped fiber yarn as the warp, with the number of floats of the weft yarn being 2 or more and 5 or less with respect to the warp yarn. The gist is a velvet-like fabric with deep color.

Hereinafter, nine aspects of the present invention will be described in detail.

In the present invention, the warp is a yarn consisting of either or both of a false twisted yarn and a composite crimped fiber.

Ultra-fine fibers with a single yarn fineness of 0.5 denier or less are used as weft yarns to form a covering part that is sequentially wound in a continuous spiral using a motor/l/twisting machine, and the core yarn is a filament fiber with a single yarn fineness of 1 denier or more. Talk composed of articles / I / Fierceness 500
By weaving a fabric in which the floating number of the weft with respect to the warp is 2 or more and 5 or less using a finely milled yarn having a denier or more and 10,000 or less denier.

To produce a velvet-like fabric with deep color.

In the present invention, a false twisted yarn or a composite crimped fiber is used as the warp, and both may be used as the warp at the same time. The false-twisted yarn referred to in the present invention is usually a high elongation, bulky, false-twisted yarn produced by a one-heater type plate combustion machine, and the composite crimped fiber is a side-by-side type or core-sheath type composite yarn. These include latent internal shrinkage type filament amber tea made of fibers.

In other words, if crimped bulky filament fibers with high elasticity are used as the warp yarns, by selecting a processing machine that does not apply tension in the length direction of the woven fabric as much as possible after rewaxing the woven fabric, the warp yarns can be used as warp yarns in the dyeing process. It is expected that the fluff density will improve due to the elasticity of the strips. Furthermore, by using 9m shrunken bulky fibers for the warp, even in the case of twill and satin wefts where the weft has a large number of floats relative to the warp, the friction between the warp and the weft is increased, making it easier to create fabrics with raised fabrics. It has the effect of almost completely eliminating dyeing accidents such as misalignment and twisting caused by the jet water stream of the liquid jet dyeing machine. In addition, in the case of pre-combusted yarn, the yarn is sufficiently heat-treated when giving crimped bulk, so the fiber structure of the yarn is stable against heat, and rope wrinkles do not occur during dyeing. , it has the advantage that woven fabrics of stable quality can be obtained because streaks are less likely to occur.

Next, the weft used in the fabric of the present invention is as follows. That is, a filament yarn with a single filament fineness of 1 denier or more is used as the core yarn of the mall yarn, and an ultrafine fiber with a single filament fineness of 0.5 denier or less is used in the covering part, and the total fineness is 50.
A 7-μ yarn of 0 to 10,000 deniers is used as the weft. This weft forms a covering part in which ultrafine fibers with a single yarn fineness of 0.5 denier or less are sequentially wound in a continuous spiral using a Mole twisting machine, and the core yarn is made of filament fibers with a single yarn fineness of 1 denier or more. An important component of the present invention is that it is a structured mall thread. A chenille yarn manufacturing apparatus is generally used to manufacture the molle yarn, and the yarn forming the decorative portion is twisted in a continuous spiral manner around the core yarn. Next, the thread is cut into two threads by a rotating disc-shaped blade, and simultaneously twisted by a burner at the bottom and wound onto a bobbin. Usually, chenille yarn manufacturing equipment uses thick filament yarns with a drop size of 1 denier or more, such as flat yarns or lame yarns with irregular cross sections, in the decorative yarn portion to create visually appealing yarns. The mall thread is then used in a portion of the jacquard weave to change the texture of the fabric, creating a three-dimensional effect.

It produces highly decorative textiles. However, although such fabrics are luxurious and aesthetically pleasing three-dimensional fabrics at first glance, they have a thick texture and feel bad to the touch.

Therefore, the present inventors were able to obtain a molding yarn with a soft feel and feel by using ultrafine fibers with a medium to fineness of 0.5 denier or less. If the single yarn fineness exceeds 0.5 denier, the texture and moist feel characteristic of ultra-fine yarns cannot be obtained, and the fabric becomes dry and hard, making it impossible to obtain a velvety-like fabric that is soft to the touch and is the object of the present invention. . 0
．． In the case of ultra-fine fibers of 5 deniers or less, the apparent Young's modulus is low due to the fineness of the single filament, and it is difficult to cut with a knife, but it can be easily cut by using a Mohr twisting machine.

This is because heating increases the apparent Young's modulus.
This is because the densification of the yarn is promoted.

It is important that the core yarn constituting the mall yarn is a filament yarn with a single yarn fineness of 1 denier or more.
When the core yarn is thinner than the denier, the apparent Young's modulus of the core yarn is low, and it is difficult to fix the ultrafine short n&fibers by heating the cut ultrafine short fibers of a constant fiber length. Also,
Since the core yarn of the molle yarn is also soft, it is necessary to increase the number of twists, and if the spindle rotation speed is constant, the productivity of the molle yarn will decrease. As mentioned above, filament fibers are used as the core yarn of the mall yarn, but in some cases, false twisted yarn having crimped bulk is preferably used as the core yarn. This is because the pre-burned yarn has many bends between the fibers, which creates a lot of friction.

If false twisted yarn is used as the core yarn, the covering part will be thicker: v1
This is because it has the advantage of reducing the shedding of one short fiber. However, by using filament yarn with a large number of twists, it is possible to obtain a molded yarn with less fluffing of ultra-fine staple fibers, and filament yarn is better suited for the dyeing process because it can be attached to temporary bridged yarn. It is suitable for obtaining fabrics with less width at the culm and fewer dates. As described above, if the core yarn is selected from either the false-twisted yarn or the filament yarn depending on the purpose of the fabric to be obtained, an ultra-fine mall yarn with little fluffing can be obtained. Also, with the core yarn? Due to the difference in fineness of the single yarn from the fine decorative yarn (covering part), a deep color can be obtained due to the luster characteristics.

In the case of the fabric of the present invention, the core yarn appears to be dyed in a dark color due to the large single filament fineness of the core yarn. Therefore, it is possible to obtain depth of color without having to uniformly align the fluff direction as in velvet fabrics. The daughter/l' fineness of the molle yarn used in the present invention is 500 denier or more and ioooo denier or less. In the case of yarns thinner than 500 denier, the fluff density is low, and only low-quality velvet-like fabrics with clearly visible core threads and base texture can be obtained. On the other hand, if the yarn is thicker than 10,000 denier, it will be a mall yarn with a high fluff density, but 2 normal vctl! 4 is difficult to weave, and even if it were possible to weave it, it would be a heavy and expensive fabric.Currently, it is only possible to weave one point with a jacquard loom, and the cost and aesthetics of the finished fabric are limited. , it is not considered to be a good idea from a performance standpoint.

For this reason, a yarn having a total fineness of 500 denier or more and 100 denier or less is preferably used as the ultra-fine mall yarn.

Next, methods for producing ultrafine fiber yarn used for the covering part of the mall yarn include a method of obtaining ultrafine fibers by dissolving and removing the sea component from multifilamentary composite fibers (seabird fibers), and a method of obtaining ultrafine fibers by dissolving and removing sea components from multifilamentary composite fibers (seabird fibers), and a method of obtaining ultrafine fibers using a static mixer. Ultra-fine by dissolving and removing one component from component-mixed spun fibers? A method for obtaining a#, a method for obtaining ultrafine fibers by a chemical weight loss method by alkali treatment of polyester/I/fibers, etc., a method for obtaining ultrafine fibers by a flash spinning method,
A method for obtaining ultrafine fibers by the Dobro method, a method for obtaining ultrafine fibers by chemically or mechanically splitting a bicomponent composite spun fiber into each component by 9%, or a method for obtaining ultrafine fibers by using the Nubindoro method or the Superdoro method. It goes without saying that any of the techniques for producing ultrafine fibers that have been proposed so far, such as a method for obtaining a A spindle type is preferably used. In the present invention, the warp and weft described above are used to weave a fabric in which the number of floats of the weft with respect to the warp is 2 or more and 5 or less. Twill texture, weft satin texture, etc. are used as the fabric texture. Plain tissue and warped satin tissue are not used. This is a flat organization.

In the case of warp satin weave, the number of floats of the weft with respect to the warp is 1,
This is because the number of weft threads inserted is smaller than that in the twill and satin wefts, so this is not a good idea in terms of improving the fluff density. When the number of floats of the weft yarns relative to the warp yarns is 6 or more, it is advantageous from the point of view of improving the fuzz density.However, the number of crossing points between the warp yarns and the weft yarns decreases, and the resistance to seam slipping decreases, resulting in problems such as misalignment during dyeing. This is undesirable because it increases the possibility of accidents such as twisting. Therefore, from the viewpoint of improving the fluff density and productivity yield, it is necessary to perform III-weaving on a fabric in which the number of floats of the weft yarns relative to the warp yarns is 2 or more and 5 or less.

For weaving, ordinary looms for spun yarn, Tao/L/Il&
Both looms and rapier looms are used. In the case of the present invention,
Although the number of weft threads inserted varies depending on the total fineness of the weft threads, it is generally about 10 to 40 threads/inch, and has the advantage of higher productivity compared to ordinary woven fabrics. The obtained fabric may be subjected to reflux scouring and dyeing processing in a conventional manner. When dyeing, dyeing is carried out using cotton that does not apply tension in the longitudinal direction of the fabric as much as possible, so that the fluff density is improved due to the crimp force of the warp threads. As a dyeing machine that does not apply tension in the length direction of the fabric, a loco-type or circular-type liquid jet dyeing machine or a wince is used, and an Ω dyeing machine such as a jigger is not suitable. Especially circular by jet stream.
A type liquid jet dyeing machine is preferably used because it is possible to maintain a relaxed state in the dyeing medium and to align the coat in a certain direction while loosening the fuzz with the force of the jet stream.

Note that the yarn used in the present invention may be any of polyester synthetic fibers, nylon synthetic fibers, acrylonitrile synthetic fibers, seveni-rose recycled fibers, and the like. In addition to obtaining the effect of nine colors from the effect of different fineness of yarns, it is also possible to give further depth of color by mixing two types of fibers with different dyeability, or by using them between the warp and weft. It becomes possible.

In this way, a velvet-like fabric with a deep color, a high fluff density, and a good feel, which is the object of the present invention, can be obtained. The resulting woven fabric is one layer thick, has little fluffing due to the characteristics of the mall yarn, and does not require backing treatment. The woven fabric of the present invention is suitable for non-clothing applications such as bag fabric, chair fabric, wall fabric, and car seat.
