Japanese Patent Laid-Open Publication No. Hei 6-316373 discloses that the outermost layer has a total winding width of 70 to 70 mm in order to reduce the shedding during unwinding.
A winding method for providing a wound portion with a winding width of 95% is described. According to this method, it is possible to reduce yarn breakage and tearing at the time of unwinding, but this is not sufficient, and when unwinding cheese wound by this method, uneven tension occurs on the yarn. However, processed yarns, such as covering yarns, and woven or knitted materials, such as tricots, using these yarns have the disadvantage of inferior quality.

[0005] In other words, the elastic yarn is unwound while being stretched about twice during post-processing to obtain a processed yarn or a woven or knitted fabric. The yarn at the end face is pulled out to the center, and unevenness in tension occurs in the yarn, and yarn breakage is likely to occur due to friction between the yarns. Further, the ear height portion is crushed by the tension of the yarn, the wound shape is deformed, and the yarn breakage and the shedding are likely to occur.

As is evident from Table 2, the elastic yarns wound in Examples 1 to 5 have a small number of yarn breaks during unwinding, and particularly when the extremely innermost layer is unwound (yarn cut 12). There were few cuts. On the other hand, since Comparative Examples 1 and 2 were wound with the set twill angle constant, the winding appearance of the package was as shown in FIG. 2, and the yarn breakage was particularly large in the inner layer during unwinding. In Comparative Example 3, since the twill angle A1 was less than 0.7A0, many yarn breaks occurred before reaching the innermost layer during unwinding. In Comparative Example 4, since the twill angle A1 was larger than A0, many yarn breaks occurred in the innermost layer during unwinding. For Comparative Example 5 T 1 is too large, there is little effect of adjusting the winding angle, cause bulges Maki took part in T 1 times, the solution舒時, yarn breakage occurred frequently before reaching the innermost layer. In Comparative Example 6, since T1 was too small, the effect of preventing the package from swelling and traversing was insufficient, and the yarn was broken in the extremely innermost layer during unwinding.
