【発明の詳細な説明】 本発明は、熱水不溶性繊維と熱水可溶性繊維とで構成さ

状部でドラフトし、仮撚を掛け。DETAILED DESCRIPTION OF THE INVENTION In the present invention, a sliver or roving (hereinafter referred to as a fiber bundle) composed of hot water insoluble fibers and hot water soluble fibers is drafted in a wet part and false twisted.

乾燥してｍき取る湿潤紡績方法に関するものである。This relates to a wet spinning method that involves drying and stripping.

法には各種の方法がある。例えば、特開昭５１−９６５

次にスチームで仮撚を掛けた後。Conventionally, there are various wet spinning methods that perform false twisting using a false twisting nozzle. For example, JP-A-51-965
The method according to No. 42 involves moistening the fiber bundle and drafting it.
Next, after false twisting with steam.

ことである。しかし、これも。It is dried and rolled up into a package, but this category a/Iiii! One of the disadvantages of the Jun-spinning method is that in order to apply false twisting with steam, the steam is applied to the r rough loaf, which causes the ruff loaf to be rolled up. But this too.

　　２００　ＷＩ／ｍｉｎ以上の高速紡績の場合には。In the case of spinning at a low speed of 200 m/min or less, the amount of steam supplied is small, so the top μ such as loaf-turning is small, and stable spinning can be performed.
In case of high speed spinning of 200 WI/min or more.

糸切れを防ぐために仮撚トルクを大きくする必要があり
、そのためにスチームの供給量を多くするので、ローラ
ー捲き付き等のトラブルが多発して。In order to prevent yarn breakage, it is necessary to increase the false twisting torque, which requires a large amount of steam to be supplied, resulting in frequent problems such as roller binding.

熱水可溶性ｍ　ＪＩの活性化の程度は。In the case of high-speed spinning, activation by steam cannot be performed completely, and therefore sufficient yarn strength cannot be achieved. In addition, the thread is powerful 1f! The degree of activation of hydrothermal soluble mJI for.

くなり。It depends on the moisture content of the fiber bundle just before drying, the temperature, and the length of the heating time. In other words, the higher the moisture content, the higher the temperature, and the longer the heating time, the faster the activation will be. The degree will be large. Therefore, if the moisture content or temperature is low, or even if the temperature is high but the heating time is short, the degree of activation will be low and yarn strength will not be fully developed, and during spinning. Yarn breakage occurs frequently, making it impossible to continue stable spinning, and only spun yarn with low yarn strength can be produced. The reduction in moisture content and heating time that lowers the degree of activation is roughly proportional to the increase in spinning speed. In other words, as the spinning speed increases, the water receiving time at the water supply point of the fiber bundle becomes shorter due to the high-speed passage, so the moisture content decreases. time becomes shorter.

き払われて減少した水分を補足して。First, air false twisting is carried out, so there is no risk of loaf twisting even when spinning at high speeds of 2001 m1n or more. Hot water is applied to compensate for water shortages due to shortening of water reception time due to high-speed passage at water supply points, and to supplement moisture lost by being blown away during air twisting.

) temperature for 1 minute in advance, so even in the subsequent false twisting with the steam false twisting nozzle, the temperature was 200ffi/min.
Despite the shortening of the passage residence time in the steam vortex nozzle QQ due to the above-described high speed 1, the activation of the hot water soluble fibers in the spun fiber bundle (1') is sufficiently carried out, resulting in yarn breakage. This makes it possible to produce high-strength yarn (1') without the need for a main draft.In addition, the spun fiber bundle (1') that has been thinned by main drafting is once applied by air false twisting nozzle/L' (2). The resulting spinning strength decreases when wetted with hot water, but by continuing false twisting with steam false twisting at 1vO5, it is greatly reinforced by activation and interaction, so it is effective at high speeds. No yarn breakage occurs during spinning.

It is an excellent spinning method that enables stable production of high-strength yarn without yarn breakage by high-speed spinning of less than 1000 yen.
