In view of these circumstances, the present invention has been made through extensive research into polyester fibers that can provide curtains that exhibit both flexibility and drapability.As a result, the present invention has surprisingly shown that the degree of birefringence of polyester fibers is significantly lower than the flexibility of curtain fabric. The present invention was achieved by discovering that the characteristics of the fabric and drapability are controlled.

That is, the present invention provides a yarn for curtains made of polyester fiber, which has an elongation at break of 40 to 80%, a degree of birefringence of 0.8 to 0.14, and a water shrinkage rate of 7% or less. This polyester fiber for curtains is characterized by having a fiber friction coefficient of 0.32 or less.

Conventionally, the polyester yarns used for curtains have simply been used for clothing, but the characteristics required for curtain yarns have not been recognized at all. Ta. In other words, conventional polyester fibers for curtains have a high degree of double fan folding,
Because the molecules that make up the fibers are highly oriented, the yarn itself lacks flexibility.

一方、この複屈折度を低下せしめると繊維の分子配向は

On the other hand, when this degree of birefringence is reduced, the molecular orientation of the fibers is reduced and the flexibility of the filament is increased.

On the other hand, if the birefringence of yarn is reduced too much, the curtain obtained from the yarn will shrink significantly in hot water and lose its flexibility. Therefore, a curtain having flexibility and drapability can be obtained by using polyester yarn having a birefringence within the range defined by the present invention.

Furthermore, in the present invention, by using polyester yarn with a lower degree of birefringence than conventional yarn for curtains, the disadvantages that occur in the manufacturing process of curtains or in the curtains obtained can be avoided by reducing the elongation at break of the yarn. , by specifying the water production shrinkage rate and fiber friction coefficient.

Here, if the elongation at break is less than 40%, especially less than 35% like the commonly used raw yarn, the raw yarn itself becomes hard (
The flexibility when used as curtains is impaired. On the other hand, if the elongation at break exceeds 80%, the yarn becomes too easy to stretch, and there is a risk that tension fluctuations during weaving or purl knitting may cause elongation strain to cause streak-like unevenness.

更に、原糸の製水収縮率を7%以下とすることが必要で

Next, it is necessary to set the fiber friction coefficient of the raw yarn to 0.32 or less, preferably 0.2 to 0.32. Say, Nomo.
The polyester yarn of the present invention has higher elongation and lower birefringence than conventional general polyester yarns, so it tends to be easily stretched by mechanical manipulation. For example, in the weaving and knitting processes, the tension applied to each single fiber is usually not constant but varies, and when the fiber friction coefficient of the commonly used raw yarn is 0835 or more, each single fiber is stretched unevenly. easy. In order to prevent this, it is necessary to run each single fiber as smoothly as possible. Therefore, it is necessary to set the fiber friction coefficient within an appropriate range suitable for smooth running.゛The method for measuring the fiber friction coefficient specified in the present invention follows the definition below.
