As shown in the example, knitting is performed using a double raschel machine exclusively for cut piles. The reeds on the front side (L1),
(L2) and the reeds on the back side (L4), (L5) guide the inserted thread and the chain thread to the front and rear needle beds (1), (2), respectively, to form the ground structure of the front and back, that is, the two front and back surfaces. , The pile yarn (p) is guided to the front and rear needle beds (1) and (2) by the reed (L3) in the central portion to guide the pile yarn (p) to the knitting needle (3),
(4) is sequentially lapped and knitted with the above-mentioned two-layered fabric, and the pile yarn (p) hung over both the two-ground fabric is cut at the center between the two-layered fabric to form a cut pile fabric. After the heat treatment, the pile is defibrated to form a napped state, and a napped material such as a blanket is finished.

【０００３】そして、前記カットパイル生地のパイル糸
としては、編成上の糸切れ防止および張力調整等を考慮
して、通常一般には例えば３２番手程度の紡績糸を２本
撚合せた所謂双糸が用いられている。The pile yarn of the cut pile fabric is generally a so-called twin yarn in which two spun yarns of, for example, about 32 count are twisted in consideration of prevention of yarn breakage and tension adjustment in knitting. It is used.

も悪くなる。However, the above-mentioned twin yarn used for the pile yarn has a higher manufacturing cost of the yarn itself than the single yarn of the thick spun yarn of about 16 count, and is a twisted yarn, as shown in FIG. In the state, since the pile (5) also has a large number of twists, the defibration property is inferior to that extent, and the defibration process must be performed 6 to 8 times, which takes time to perform the defibration process. As a result, the cost of producing a napped fabric is high. Moreover, as the number of defibration treatments increases, the fibers that become napped are more likely to be damaged or come off, and the napped state of the fibers also deteriorates.

May occur, and it is difficult to adjust the tension to cause uneven knitting, and since the fibers of the cut pile are twisted, it is necessary to repeat the defibration process many times. It does not happen.

じくＺ撚単糸である。FIG. 1 is an enlarged schematic view of a pile yarn portion of a napped fabric according to the present invention, wherein (6) is a ground yarn, (5) is a pile,
(7) is an S twist single yarn that constitutes the pile (5), and (8) is a Z twist single yarn.

The twisted single yarn (8) is defibrated so that the short fibers are arranged substantially parallel to each other, and the twist remains in the ground texture vicinity portion (B). That is, it can be seen that the tip portion (A) is defibrated so as to be easily arranged in parallel by performing the defibration process.

下する。Here, the pile (5) will be further described. As the pile (5), a twin-spun spun yarn is used. This twin-spun spun yarn is about 28 to 48 consisting of short fiber bundles having a fiber length of 5 inches or less.
Twisted single yarn is aligned and combined. The number of twists of the S twist single yarn and the Z twist single yarn is such that the twist coefficient (k) represented by the number of twists per 1 meter / (metric number) ^1/2 is 55 to 7
It is necessary that the numbers are substantially the same within the range of 0.
As described above, when the S twist yarn and the Z twist yarn having substantially the same number of twists are combined, a sufficient converging action occurs due to the upper twist to form a double yarn, and apparent twist disappears as the double yarn. , Becomes a flat yarn. It is presumed that this is because the fluff present on the surface of each single yarn is entangled with each other's torque and cancels the twist of each other. For this reason, if the twist (coefficient) of each single yarn is less than the above range, the torque required for entanglement is not sufficiently generated, and the convergence of the twin yarn decreases. Further, the above fiber length is required in order to impart a sufficient number of twists. On the other hand, if there are too many twists (coefficients), the entanglement part cannot completely offset the torques of the opposite sides and twists occur as twin yarns, which complicates the defibration process described later and deteriorates the defibration state, resulting in bulkiness. Is reduced.

It is necessary to be within the range of, preferably within the range of 30 to 50. If the twisting factor during compounding is less than 30, the yarn is left in a long yarn path without tension, or when the tension floats between the creel and the knitting machine, snarl is partially generated. One of the twisted threads does not hang on the knitting needle, resulting in inconvenience. When the twisting coefficient exceeds 60, the defibration cannot be sufficiently performed in the subsequent defibration step.

If the shrinkage ratio after steaming at 110 ° C. for 20 minutes is less than the above range, or if the content of shrinkage ratio is 20% or more is less than the above range, the obtained napped fabric may lack bulging feeling.

なっている。The napped fabric of the present invention uses, as the pile yarn, the double yarn in which the S twist single yarn and the Z twist single yarn having the same number of twists are twisted with a twist coefficient of 30 to 60. Since the interference force between them is small and the fiber can be easily disentangled, the napped fibers are not damaged or come off easily, and the napped state is good.
