DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a warp knitted fabric mainly used for blankets and the like, and more particularly to a method for producing a warp knitted fabric having different colors in a vertical direction of a pile.

[0002]

2. Description of the Related Art Conventionally, a raised fabric made of a warp knitted cut pile fabric which is preferably used for a blanket or the like is knitted using, for example, a double raschel machine dedicated to cut pile having a structure shown in FIG. Reeds (L1), (L2)
And the back side reeds (L4) and (L5) guide the inserted yarn and chain yarn to the front and rear needle beds (11) and (12), respectively.
A ground texture is formed on the front and back, that is, on both front and back sides, and the pile yarn (P) is moved by the reed (L3) at the center to the needle bed (1).
The pile yarn (P) is led to knitting needles (1) and (1) and (12).
3) and (14) are sequentially wrapped and knitted together with the two-sided structure. The pile yarn (P) thus wrapped around the two-sided structure is cut at the center of the two-sided structure. The fabric is obtained, and then the pile is defibrated by dyeing or wet heat treatment, and dried to form a nap-like shape, and is finished into a nap-like product such as a blanket.

[0003] Conventionally, warp knitted wool fabrics having different colors in the vertical direction of the pile have been developed in various ways and are widely available on the market. However, many of these dyes penetrate the dye from the back of the base fabric to dye the root of the pile, or paste the dye containing the dye with a roller or the like at the tip to dye the tip of the pile, such as a printing paste. A method of applying such a material, or a method of penetrating the tip portion into a staining solution is used. However, in these methods, it is extremely difficult to uniformly attach the dye to the pile, and it may be practically impossible.

For example, in a method in which a dyeing solution is permeated from behind a base cloth, or only the tip of a pile is immersed in the dyeing solution, it is very difficult and almost impossible to achieve uniform and controlled dyeing. That is, in pile products, piles touch each other,
It is in the form of a bundle, during which a capillary is formed, and the staining solution is irregularly diffused to an unintended location by capillary action,
This is because contamination occurs. When the viscosity is increased by using a sizing agent in the dyeing solution in order to prevent the capillary phenomenon, it is extremely difficult to attach such a highly viscous material to a pile which is easy to fall over a wide range of the product uniformly and at a target place. . Therefore, in the conventional method, even if various color changes are given only to a certain part of the piloerection, different color changes often occur in other places, and the color-changed coloring state is local, and the entire product or It cannot be said that it is a uniform thing over a wide range.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to provide a warp knitted hair having a uniformly colored pile over a whole product or a wide range of products. The purpose is to provide a method for obtaining the dough. Here, the color change state is a state in which the color changes in the length direction of the raised pile, for example, a state in which the tip portion, the center portion, the root portion, and the like are colored differently from other portions.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to knit a double-sided structure using a double Russell machine by using a spun yarn made of an acrylic synthetic fiber and a regenerated cellulose fiber provided with an anionic oil agent as a pile yarn. This is achieved by a process for producing warp knitted napping fabric, which comprises cutting the pile yarns at the center of the two fabrics, then coloring with a cationic dye, and defibrating the pile which has been cut by humidity heat treatment.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, the present invention will be described in detail.

First, as a spun yarn used for a pile yarn,
A mixture of acrylic synthetic fibers and regenerated cellulose fibers to which an anionic oil agent has been applied is used. A mixture of acrylic synthetic fibers and regenerated cellulose fibers to which an anionic oil agent has been applied is used. Mixing of acrylic synthetic fiber and regenerated cellulose fiber with anionic oil
There is no particular limitation on cotton blending, plying yarn and the like. The mixing ratio of the acrylic synthetic fiber and the regenerated cellulose fiber provided with the anionic oil agent is preferably 90 to 60 (% by weight): 10 to 40 (% by weight). As the acrylic synthetic fiber, 40% by weight or more of acrylonitrile and other vinyl monomers such as acrylic acid, methacrylic acid, or alkyl esters thereof, vinyl acetate, vinyl chloride, vinylidene chloride, sodium allyl sulfonate, Sodium methallylsulfonate, sodium vinylsulfonate, sodium stillsulfonate, sodium 2-acrylamido-2-methylpropanesulfonate, and the like are appropriately combined and copolymerized at a ratio of 60% by weight or less. Examples of the regenerated cellulosic fibers include rayon, polynosic, cupra, purified cellulosic fibers (trade name: Tencel) and the like.

In the same manner as in the prior art, a reed (L1),
(L2), (L4) and (L5) guide the inserted yarn and chain yarn to the front and rear needle beds (11) and (12), respectively, to knit the ground structure on the front and back, that is, the front and back surfaces, and to reed (L3). )
In this way, the pile yarn (P) is guided to the front and rear needle beds (11) and (12) to be sequentially wrapped by the knitting needles (13) and (14) of the front and rear needle beds and knitted together with the above-mentioned two-layer structure. FIG. 2 is an exploded view of the wrapping motion of the insertion reed (L1) and the chain reed (L2), the pile reed (L3) and the back side reed (L4) and the insertion reed (L5). Knitting in knitting organization. Immediately after this knitting, the pile yarn (P) stretched over the two fabrics is cut at the center between the two fabrics to obtain a warp-knitted pile fabric.

The warp knitted cut pile fabric obtained as described above is colored by dyeing or printing using a cationic dye. As the cationic dye, a general cationic dye may be used, but it is particularly preferable to use a dispersion type cationic dye in order to obtain a pile in a color change state.
In addition, the dispersion type cationic dye refers to a dye in which a cationic dye and an anionic dispersant are combined and further dispersed by an excess of an anionic dispersant.

[0011] After coloring, further wet heat treatment with steam or the like,
Wash and dry. Subsequently, a defibrating process is performed using a known defibrating machine or a raising device. Further, after the defibrating treatment, when the physically elongation treatment of the napped portion accompanied by the heat treatment is performed by using a polisher, the surface of the napped article becomes smooth and the quality is improved. Thereafter, the warp knitted napping fabric of the present invention is obtained by shearing (shearing) to make the naps of a certain length. In addition, when a softening agent or a stiffening agent is applied before the defibration, the defibration property is further improved.

[0012]

Next, embodiments of the present invention will be described more specifically with reference to examples.

Example 1 A 3-denier acrylic short fiber having a bias cut of 102 mm was set on a well-known spinning machine, and was set at 28th in the Z twist direction of 335.
A spinning yarn of T / M (twist coefficient 63.3) was made. Meanwhile, 1
A rayon fiber provided with a 3-denier anionic oil agent having a bias cut of 02 mm was set on a known spinning machine,
A spinning yarn having a Z twist direction of 335 T / M (twist coefficient: 63.3) was produced with a count. Further, a twin yarn of 230 T / M (twist coefficient 61.5) in the upper S twist direction was obtained from the above two types of spun yarns. This is used as a pile yarn, and a polyester filament yarn of 200 denier 48 filaments is used as a chain yarn, and 340 is used.
Using a denier 48 filament polyester filament yarn as the insertion yarn, a knitted structure of both sides shown in FIG. 2 was knitted (using a 16 gauge curl Meyer machine). Then
The pile yarn at the center between the two background structures was cut (center cut) with a cutter having a belt traveling type blade to obtain a warp-knitted pile fabric.

Then, a dispersion-type cationic dye (0.5 g of Cathilon Blue FB-DP) is prepared by a known method.
/ L), immersed in a dye liquor containing an acid and a known slow dye, squeezed using a mangle, heat-treated at 100 ° C. for 20 minutes with a continuous steamer, soaped by a known method, and dried after applying a softener. . Next, it is passed through a two-cylinder quadruple type hair remover once in the reverse direction of the pile length and once in the forward direction, and after defibration, the tip of the bristle is stretched with a polisher at 110 ° C. The tip was sheared to obtain a product of Example 1 of the present invention.

Comparative Example 1 In Example 1, the spun yarn obtained from the acrylic staple fiber was subjected to 230 T / M in the S-twist direction (twist coefficient 61.
The same process as in Example 1 was performed except that the twin yarn twisted in 5) was used as the pile yarn, to obtain a product of Comparative Example 1.

The product obtained in Example 1 had a different color in the vertical direction of the pile, whereas the product obtained in Comparative Example 1 had a uniform color in the vertical direction of the pile without being different. .

The warp knitted wool fabric obtained by the method of the present invention has a pile swelling feeling and a stiff feeling, and has a different color in the vertical direction of the standing pile, so that the color changes three-dimensionally when the pile shakes. It has an elegant color and is very useful for blankets and the like.
