DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a napping fabric for a bore. More specifically, the present invention relates to a napping fabric for a bore that has a soft texture, a good pile recovery, a voluminous feel, and particularly, an excellent feel and voluminous feel even after washing with water.

[0002]

2. Description of the Related Art Conventionally, polyacrylonitrile-based fibers have been used for pile yarns of napkin products such as stuffed toys and blankets, and soft texture is generally widely accepted. In addition, as the taste of the texture is softened, the fineness of the single yarn of the pile yarn is reduced to a fine decitex. However, when the fineness of the single yarn is reduced to fine decitex, the bending rigidity is reduced. Therefore, when the napping fabric is left in a roll wound with a piece of cloth, or in a stuffed product, there is a problem that hair falls, poor pile recovery, and lack of volume. Has occurred. In addition, with the growing desire for cleanliness, there is a growing demand for washing stuffed products at home.However, after washing with water, piles may fall off, or piles may become entangled or converged. Has occurred.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a soft texture, good pile recovery, less hair breakage, and a voluminous feel, which characteristics are maintained even after washing with water. The purpose of the present invention is to provide a brushed bore fabric.

[0004]

Means for Solving the Problems The present inventor has studied the above problems in detail, and as a result, at least using polytrimethylene terephthalate fiber for the pile yarn,
The present inventors have found that a brushed fabric for a bore having a soft texture, extremely good pile recoverability and voluminous feel, and maintaining the properties even after washing with water can be obtained, thereby completing the present invention. That is, the present invention relates to a bored napping fabric comprising a pile yarn and a ground yarn constituting a ground structure, wherein at least the pile yarn is formed of polytrimethylene terephthalate fiber.

Hereinafter, the present invention will be described in detail. The napped fabric referred to in the present invention refers to all the napped fabrics composed of pile yarns and all the fabrics composed of ground yarns constituting the ground structure. For example, a double-layered loom or a double-structured cloth made by a double Russell knitting machine or the like is cut at the center, a pile knitting machine made of a warp knitting machine or a circular knitting machine such as a tricot, or a ground portion is sheeted using a seal milling knitting machine. In the case of knitting, there may be mentioned a form in which nap component fibers are sandwiched in a loop and the tip of the loop is cut.

In the present invention, the phrase that the pile yarn is composed of polytrimethylene terephthalate fiber means that the pile yarn is composed of polytrimethylene terephthalate fiber and another fiber in addition to the case where only the polytrimethylene terephthalate fiber is used for the pile yarn. Including the case. The ratio of the polytrimethylene terephthalate fiber to the entire pile yarn is 30 to
It is preferably 100% by weight, more preferably 50 to 100% by weight. If the proportion of the polytrimethylene terephthalate fiber is less than 30%, satisfactory pile recovery and voluminous feel cannot be obtained. In addition, by using polytrimethylene terephthalate fiber for the pile yarn, the fabric is extremely flexible as a bore fabric, and because it is flexible, it can easily conform to a three-dimensional shape and has an advantage that a stuffed toy of a complicated shape can be easily made. .

The type of fiber other than polytrimethylene terephthalate fiber used for the pile yarn is not particularly limited. For example, conventionally known various fibers such as cellulosic fiber, acetate, ester, nylon, acryl, polypropylene, cotton, hemp, One or more kinds of natural fibers such as silk and wool are used, and these fibers can be mixed with the fibers by twisting or blending. The polytrimethylene terephthalate fiber used in the present invention refers to a polyester fiber having a trimethylene terephthalate unit as a main repeating unit, and the trimethylene terephthalate unit has about 50 mol% or more, preferably 70 mol% or more, and more preferably 80 mol% or more. %, More preferably 90 mol% or more. Therefore, the total amount of the other acid component and / or glycol component as the third component is about 50 mol% or less, preferably 30 mol% or less, more preferably 20 mol% or less, and still more preferably 10 mol% or less. Polytrimethylene terephthalate.

[0008] Polytrimethylene terephthalate is produced by polycondensing terephthaleric acid or a functional derivative thereof with trimethylene glycol or a functional derivative thereof in the presence of a catalyst under appropriate reaction conditions. In this production process, an appropriate one or two or more third components may be added to form a copolymerized polyester,
Alternatively, polyester, nylon and polytrimethylene terephthalate other than polytrimethylene terephthalate such as polyethylene terephthalate may be separately produced and then blended or composite spun (sheath core, side-by-side, etc.).

The third components to be added include fatty acid dicarboxylic acids (oxalic acid, adipic acid, etc.), alicyclic dicarboxylic acids (cyclohexane dicarboxylic acid, etc.), and aromatic dicarboxylic acids (isophthalic acid, sodium sulfoisophthalic acid, etc.). , Aliphatic glycols (ethylene glycol, 1,2
-Propylene glycol, tetramethylene glycol, etc.), alicyclic glycols (cyclohexanediol, etc.), aromatic dioxy compounds (hydroquinone bisphenol A, etc.), aliphatic glycols containing aromatics (1, 4
-Bis (β-hydroxyethoxy) benzene, etc.), polyether glycols (polyethylene glycol, polypropylene glycol, etc.), aliphatic oxycarboxylic acids (ω
-Oxycaproic acid), aromatic oxycarboxylic acids (P
-Oxybenzoic acid, etc.). Further, a compound having one or three or more ester-forming functional groups (such as benzoic acid or glycerin) can be used as long as the polymer is substantially linear. Further, matting agents such as titanium dioxide, stabilizers such as phosphoric acid, ultraviolet absorbers such as hydroxybenzophenone derivatives, crystallization nucleating agents such as talc, lubricating agents such as aerosil, antioxidants such as hindered phenol derivatives, A flame retardant, an antistatic agent, a pigment, a fluorescent brightener, an infrared absorber, an antifoaming agent, and the like may be contained.

In the present invention, the polytrimethylene terephthalate fiber is spun at a take-up speed of about 1500 m / min to obtain an undrawn yarn, and then stretched at a rate of about 2 to 3.5 times. Any of a direct drawing method in which a spinning-drawing step is directly connected and a high-speed spinning method (spin draw or spin take-up method) with a winding speed of 5000 m / min or more may be adopted. The fineness of single yarn is preferably 0.1 to 6 dtex. The form of the polytrimethylene terephthalate fiber is not particularly limited, and it may be a staple or a filament. However, a filament which causes less falling off of the pile yarn during washing with water and has little change in properties is preferable. The filament may be a raw yarn or a textured yarn subjected to bulky processing such as false twisting, but a bulky textured yarn is preferred from the viewpoint of improving the volume.

In the present invention, the straightness of the tip of the pile yarn is preferably 70 to 100%, particularly preferably 75 to 100%. If the straightness of the pile yarn tip is less than 70%, the hair elongation is insufficient, and it is difficult to obtain a soft texture. The linearity of the pile yarn tip is measured as follows. That is, the side surface of the pile is imaged with a scanning electron microscope, and the image is analyzed with image analysis software (for example, “IP-1000” manufactured by Asahi Kasei Corporation).
PC ”). From the tip of the straight line drawn perpendicular to the ground texture from the tip of the pile yarn, a straight line parallel to the ground texture passing through a point of 20% length is determined, and the point at which the straight line intersects with the pile texture is determined. The linear length L1 between the crossing point and the two points at the tip of the pile yarn and the length L2 along the pile yarn are measured, and L1 / L2
X100 is used to calculate the linearity of the pile yarn tip.
Twenty single yarns constituting the pile are arbitrarily selected, and the linearity of each single yarn is averaged to obtain the linearity of the tip of the pile yarn. In the present invention, the pile yarn tip angle is 70 to 90.
Degrees, particularly preferably 75 to 85 degrees. If the pile yarn tip angle is less than 70 degrees, it is difficult to obtain a plump appearance and the appearance is inferior in volume. The pile yarn tip angle is the angle between a straight line parallel to the ground structure obtained by the above-described measurement of the linearity and a straight line connecting the pile tip and an intersecting point.

A method for setting the straightness and angle of the pile tip to predetermined values is to trim the pile yarn by brushing with needle cloth or animal hair, determine the pile angle, and then use a heat brush or a heat polisher. Fix the pile angle and stretch the hair. In the present invention, in this brushing step,
Due to the mechanical properties of the pile yarn, the hair is very well trimmed, there is almost no entanglement of the single yarn forming the pile yarn, and the pile is excellent in uprightness. Furthermore, from the mechanical properties of the pile yarn during heating,
Extremely good hair elongation due to thermal polisher, etc., and excellent linearity at the part in contact with the polisher. Also,
Once the pile angle and straightness are fixed, the pile yarn's mechanical properties, especially its excellent elongation recovery and compression recovery, and little change in wet properties, act synergistically to make the pile recoverable and voluminous. Is maintained over a long period of time, and it is estimated that the properties are maintained even after washing with water. The ground yarn constituting the ground structure may be any fiber such as cotton, cupra, rayon, purified cellulose fiber, polyester, polyamide, and synthetic fiber such as polytrimethylene terephthalate fiber, if the object of the present invention is achieved. The form may be a filament or staple, a raw yarn,
Any form such as a mixed fiber, a mixed spun yarn, and a false twist yarn may be used.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described specifically with reference to examples, but the present invention is not limited to the examples. In addition, physical property evaluation was performed by the following methods. (1) Recoverability of pile The piled fabric was subjected to a load of 100 g / cm ² , allowed to stand for 24 hours, and after removing the load, observed from the upper surface and judged by sensory evaluation. (2) Feeling of Volume The napping fabric was compressed with the palm of the hand and judged by sensory evaluation. (3) Along the three-dimensional shape The shape of the napping cloth for bore cut into a 20 cm square was placed on a sphere having a diameter of 15 cm, and the shape was visually judged to determine whether or not the three-dimensional shape was good. (4) Appearance after washing with water A nappied cloth was washed with water and dehydrated with a neutral detergent in a home dry course of a commercially available one-tank type fully automatic washing machine at a bath ratio of 1:30, then hung to dry in the shade and dried. After repeating this washing-drying cycle five times, the appearance was sensory evaluated.

<Production method of polytrimethylene terephthalate fiber> Polytrimethylene terephthalate having ηsp / c = 0.8 (measured at 35 ° C. using o-chlorophenol as a solvent) is spun at a spinning temperature of 265 ° C. and a spinning speed of 1200 m / min. Then, a hot roll temperature of 60 ° C., a hot plate temperature of 140 ° C., a draw ratio of 3 times, and a draw speed of 8 were obtained.
Stretching was performed at 00 m / min to obtain a drawn yarn of 132 dtex / 60f. The strength, elongation, elastic modulus and elastic recovery at 10% elongation of the drawn yarn were 2.9 g / dtex and 46, respectively.
%, 27.3 g / dtex and 98%.

[0015]

Example 1 The obtained polytrimethylene terephthalate fiber filament raw yarn 132 dtex / 60f was used as a pile yarn, and a polyester filament 110 dt was used as a ground yarn.
After weaving with a double pile loom using ex, backing was performed by a conventional method, and dyeing, polishing, and shirring were performed to prepare a napped fabric. The linearity and angle of the pile yarn tip of the obtained napping cloth were 85% and 8%, respectively.
It was 0 degrees.

[0016]

Comparative Example 1 0.9 dtex shrinkable acrylic fiber 40
A spun yarn consisting of 60% by weight of non-shrinkable acrylic fiber of 1.1% dtex and 1.1 dtex was used for the pile yarn, woven and backed in the same manner as in Example 1, and then dyed, split, polished, sheared, and raised. A fabric was obtained. The straightness and angle of the pile yarn tip of the obtained napping fabric are 8 and 8 respectively.
0%, 80 degrees. The napped fabric obtained in Example 1 had good pile recovery and a good voluminous feel. Since the fabric is flexible, when placed on a sphere, the distance between the end of the fabric and the sphere is small, the formation of the node is good and the silhouette is beautiful, and the evaluation is that the shape along the sphere is good. In addition, the appearance, pile recovery, and voluminousness after washing with water were almost the same as before washing, and were favorable. On the other hand, in Comparative Example 1, the pile recovery was poor, and the voluminous feel was inferior to that of Example 1. When placed on a sphere, the distance between the edge of the fabric and the sphere was large, and along the sphere was not sufficient. After washing with water, a portion where the ends of the pile yarn were entangled and converged was scattered, and the quality was extremely poor. In addition, the recoverability and voluminous feel were further inferior to those of Example 1.

[0017]

According to the present invention, while having a soft texture, the pile has good recoverability, has a voluminous feel, and is soft as a fabric. It is possible to provide a brushed fabric for a bore that is easy to make and maintains excellent texture and voluminous feeling even after washing with water.
