Yes, this is necessary in order to develop the effects of the present invention such as lightness and heat retention. It can also be mixed with other fibers.
本発明でいう布帛とは，織物，編物，不織布を意味し，
いずれかに限定されるものではない。The cloth referred to in the present invention means a woven fabric, a knitted fabric, and a non-woven fabric,
It is not limited to either.
本発明のもう一つの特徴は，上述の交絡糸からなる布帛

上でなければならない。該クロー値が0.3clo/cm未満で
あれば，本発明の効果である保温性が不十分である。Another feature of the present invention is that the cloth made of the above-mentioned entangled yarn must have a claw value of 0.3 clo / cm or more and a specific volume of 1 cm 3 / g or more. The claw value here is
An index of heat retention expressed in the unit of heat resistance of clothes, which is 21
In a room environment of ℃, relative humidity of 50% or less, and airflow of 10 cm / sec, a Caucasian standard boy who is comfortable sitting in a chair feels comfortable and can maintain an average skin temperature of 33 ° C. I decided to keep the warmth of the clothing on 1clo,
Since there are changes such as individual differences, a reasonable physical clo value is defined as 1clo = 0.18 ℃ ・ m 2・ hr ・ Kcal -1. The larger the value, the greater the heat retention. There is. In the fabric of the present invention, the above-mentioned claw value must be 0.3 clo / cm or more. If the claw value is less than 0.3 clo / cm, the heat retaining property, which is the effect of the present invention, is insufficient.
本発明の布帛の比容積は,1cm3/g以上であることが必須
で，本発明でいう比容積とは，一定重量当たりの占める
体積のことを意味し，cm3/gで表されるものであり，比
容積が大きいということは布帛が軽量であることを指し
ている。本発明の布帛では，比容積が１cm3/g以上であ

であり，本発明の布帛のもう一つの効果である保温性の
点でも有利である。すなわち，布帛の比容積が大きくな
れば，布帛の体積に占める繊維固型分の比率が小さくな
り，空気の占める割合が増加することにより含有空気量
が増加し，保温性も良好となる。The specific volume of the fabric of the present invention is essential to be 1 cm 3 / g or more, and the specific volume in the present invention means the volume occupied by a certain weight and is expressed in cm 3 / g The fact that the specific volume is large means that the cloth is lightweight. In the fabric of the present invention, it is necessary for the fabric of the present invention to have a specific volume of 1 cm 3 / g or more for its light weight, which is an effect of the fabric of the present invention, and another point of heat retention, which is another effect of the fabric of the present invention. But it is advantageous. That is, when the specific volume of the cloth is increased, the ratio of the fiber solid component to the volume of the cloth is decreased, and the ratio of the air is increased, so that the amount of air content is increased and the heat retaining property is also improved.
一方，布帛の比容積が１cm3/g未満であれば，本発明の
布帛の効果である軽量性の点で不十分となる。さらに，
本発明の布帛のもう一つの効果である保温性の点におい
ても，布帛内の含有空気量が減少し，不利である。On the other hand, if the specific volume of the cloth is less than 1 cm 3 / g, the effect of the cloth of the present invention, that is, the lightness, is insufficient. further,
Another advantage of the fabric of the present invention is heat retention, which is disadvantageous because the amount of air contained in the fabric is reduced.

めると推察される。The fabric of the present invention is the entangled yarn whose constituent fibers are the hollow section filament yarn and the false twisted filament yarn as described above, but the lightness of the hollow section filament yarn and the air inside the yarn Thermal insulation is not damaged by entanglement, and the air content is increased due to the bulkiness of the false twisted filament yarn that is entangled with the hollow cross-section filament yarn. It is presumed that.
その上，本発明では中空断面フィラメント糸条として中
