糸を均一に蒸気処理する方法に関するものである。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for steam-treating a yarn, and more particularly, to a method for uniformly steaming a silospan spun yarn or a single yarn spun yarn made of wound synthetic fibers loaded in a closed steam treatment kettle. It relates to the method of processing.

The reeds (L1), (L
2) and the reeds (L4) and (L5) on the back side guide the inserted yarn and the chain yarn to the front and rear needle beds (11) and (12), respectively, to form the front and back, that is, the ground structure of the front and back two surfaces, The pile yarn (P) is guided to the front and rear needle beds by the reed (L3) at the center, and the pile yarn (P) is sequentially wrapped by the knitting needles (13) and (14) and knitted together with the two-layered structure. The pile yarn (P) thus laid over the front and rear fabrics is cut at the center between the two fabrics to obtain a cut pile fabric.
It is to be finished to a napping fabric such as a blanket.

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 obtained by twisting two spun yarns of, for example, about 32 counts in consideration of yarn breakage in knitting and tension adjustment. Used.

Attempts have been made to use single yarn spun yarns having a high count or a thick yarn. However, silospan spun yarns and single yarn spun yarns have a high untwisting power, and when mounted on the creel of a double raschel machine, a twisting torque is generated between the creel and the double raschel machine due to the twisting torque, making smooth knitting difficult. .

った。[0005] Such a problem is solved by steam treatment of the yarn. A winding layer of a silospan spun yarn or a single yarn spun yarn made of synthetic fiber is loaded into the steam treatment kettle, and the pressure inside the steam treatment kettle is reduced. Is reduced to below atmospheric pressure, and then steam is passed through the wound layer. However, for example, a 2.5 kg wound cone (silospin spun yarn made of acrylic staple fiber) is loaded into a closed type steam processing vessel, which is sealed, and a vacuum pump is first operated to reduce the pressure in the processing vessel to 40 mmHg. The pressure is reduced, and this state is continued for 10 minutes. Then, the vacuum pump is stopped, saturated steam is fed into the processing tank, and steam is circulated through the wound layer.
When steamed at 25 ° C. for 25 minutes, the temperature difference between the inner and outer layers of the wound layer becomes 20 ° C. or more, and set unevenness occurs in the inner and outer layers of the wound layer. For example, when a warp knitted fabric is formed by using the yarn having the set unevenness as the pile yarn, unevenness occurs in the twist release when cutting and dyeing the pile yarn at the center, and a vertical blanket or blanket is used. There was a problem that streaks occurred.

As a result, the pressure in the steam treatment vessel is reduced to below atmospheric pressure, and then steam is passed through the wound layer. The inventors have found that the set spots disappear by repeating the process twice or more, and have made the present invention based on this finding.

This is a yarn spun by the method described in JP-A-57-51824, and the outline of the method will be briefly described with reference to FIGS. 2 and 3.

Immediately after leaving the nip point, it is wound around the bobbin (6) in the form of a plied yarn (5) by the twisting action of the ring traveler mechanism (4).

の温度差が大きく、セット斑が発生するからである。In the present invention, when a wound layer of a silospan spun yarn or a single yarn spun yarn made of such a synthetic fiber is loaded into a steam treatment pot and heat-set with steam, first the pressure in the steam treatment pot is increased. It is essential that the step of reducing the pressure to below the atmospheric pressure and then allowing the steam to flow through the wound layer is repeated twice or more. If the pressure in the steam treatment tank is reduced to the atmospheric pressure or less, and then the steam is circulated through the yarn layer once, the temperature difference between the inner and outer layers of the wound layer is large as described above, and set spots are generated. Because it occurs.

20分程度で良い。The pressure in the steam treatment tank, that is, the residual air pressure is 1
It is preferable that the pressure is 160 mmHg or less in both the first and second times. If the residual air pressure exceeds 160 mmHg, it is difficult to replace the air with steam. The temperature at which the steam is passed through the winding layer is preferably 50 ° C. or more and 80 ° C. or less, and particularly preferably 50 ° C. or more and 70 ° C. or less for both the first and second times. If the temperature is lower than 50 ° C., the setting effect is small. In addition, the time to make the steam flow through the yarn layer is 5 to 5.
About 20 minutes is enough.

糸巻き層の空気は容易に排除されるようになる。For example, the official moisture regain of acrylic fiber is 50% and the equilibrium vapor pressure is several mmHg. For example, if the pressure is reduced to a residual air pressure of about 50 mmHg which is the limit of the performance of a normal vacuum pump, 40 mmHg is obtained. Some air will remain. When steam treatment is performed in this state, the steam condenses on the wound layer, the air is pushed inside by the steam that enters later, the air pressure increases, the steam pressure decreases, and the temperature difference between the inner and outer layers of the wound layer Will occur. However, when the pressure inside the steam processing tank is reduced again, the vapor pressure in the wound layer becomes considerably high, so that the air in the wound layer can be easily removed.
