れる場合が多い。2. Description of the Related Art Acetate fibers have a high gloss and a dry feel, a deep color tone, and are excellent in affinity with other fibers, but have a lack of swelling and lightness. This is attributable to the basic spinning method of raw yarn production, in which acetate fibers are manufactured by a dry spinning method. However, even in the case of acetate fibers, diversification of consumer needs has led to a demand for fibers having a swelling feeling and a light weight feeling. For this reason, for example, a method in which the nozzle shape is deformed in the spinning process to make the fiber an irregular cross section, or There have been proposed methods of bulking the fibers by post-processing, but in these methods, the swelling feeling is not sufficient, or even if the swelling feeling is obtained, firmness and stiffness are often impaired.

A method has also been proposed (Japanese Patent Publication No. 43-25941) in which composite spinning is performed using a kind of acetate spinning stock solution and crimping is performed by hot water treatment, but a certain degree of swelling is obtained, but satisfactory swelling is obtained. I haven't gotten it. The present invention, which is an application of the composite spinning technique, is an acetate fiber produced by a dry spinning method by a combination of a combination of two components having different degrees of acetylation and an alkali treatment after fiberization. However, it was made as a result of study to obtain acetate fibers having a swelling feeling and a light feeling. An object of the present invention is to provide an acetate conjugate fiber having a swelling feeling and a lightweight feeling.

ができる。In the alkali treatment, for example, an alkali compound such as sodium hydroxide, potassium hydroxide, calcium carbonate or the like is used, and the precursor fiber is immersed in a solution of such an alkali compound and impregnated by padding or the like. The processing solution concentration, processing temperature, and processing time in the alkali processing are as follows:
Although it depends on the alkali compound used and the target product, preferred alkali treatment conditions include, when an aqueous solution of sodium hydroxide is used, the concentration of sodium hydroxide does not exceed 5% by weight, and the treatment temperature is 30 to 100.

よりふくらみ感、軽量感を奏する。[0010] The precursor fiber is deacetylated by being affected by the alkali treatment. Among the composite components, cellulose triacetate is hardly affected, and cellulose diacetate which is susceptible to the alkali treatment is reduced. At the same time, the cellulose acetate is converted into cellulose acetate having a low degree of acetylation or further into cellulose, whereby an acetate composite fiber having a relatively increased composite ratio of cellulose triacetate is obtained. Also, due to the difference in the effects of the alkali treatment of each composite component of the precursor fiber, a difference in shrinkage occurs between the composite components, and the obtained acetate composite fiber exhibits a large crimping property as described above. Due to the improvement in bulkiness, a swelling feeling and a lightweight feeling are achieved.

Since cellulose or cellulose acetate having an average degree of acetylation of less than 48.8% is present on the fiber side surface, conventional acetate fibers can be made into fibers having more water absorption and hygroscopicity.
