Description of the Prior Art Acetate fibers have a high gloss, a dry feel, a deep color tone, and an excellent affinity with other fibers, but on the other hand, they have a slight lack of swelling and softness. This is due to the basic spinning method of the raw yarn production, in which the acetate fibers are produced by the dry spinning method. However, even with acetate fibers,
Due to diversifying consumer needs, fibers having a swelling feeling and a soft feeling are demanded. Therefore, for example, a method in which the nozzle shape is modified in the spinning process to make the fibers have an irregular cross section, or the fibers are bulk processed by post-processing. Although methods and the like have been proposed, in these methods, the swelling feeling is not sufficient, or the swelling feeling is often lost even if the swelling feeling is obtained.

A method of providing a crimp by composite spinning using a single kind of acetate spinning dope and applying hot water treatment has also been proposed (Japanese Patent Publication No. 43-25941), but a swelling feeling to some extent can be obtained, but a satisfactory swelling feeling is obtained. I haven't got it. INDUSTRIAL APPLICABILITY The present invention, to which the composite spinning technology is applied, is an acetate fiber produced by a dry spinning method by a combination of a composite 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 an acetate fiber having a swelling and soft feeling. An object of the present invention is to provide an acetate composite fiber having a swelling feeling and a soft feeling.

抑制され、ふくらみ感が低下する。The acetate conjugate fiber of the present invention has a side-by-side composite structure in which cellulose or cellulose acetate having a low acetylation degree and cellulose triacetate having a high acetylation degree are laminated in parallel, and one of the low-component components is a low component. Acetylation degree Cellulose acetate has an average acetylation degree of less than 48.8%, and has an acetylation degree lower than the acetylation degree of 48.8 to less than 56.2% of cellulose diacetate. On the other hand, the other complex component, cellulose triacetate with a high degree of acetylation, has an average degree of acetylation of 5
It has a high degree of acetylation of 6.2 to 62.5%.
Cellulose or cellulose acetate having a low acetylation degree and cellulose triacetate having a high acetylation degree have a weight ratio of 35 :.
65: 5: 95, preferably 35: 65-20: 80, and when the ratio is out of this range, the fibers have a feeling of swelling but have no elasticity or stiffness.
When the cellulose or the low acetylated cellulose acetate is larger than the above ratio, the suppleness of the fiber is lost,
It has a relatively hard texture. On the other hand, when the content of the cellulose triacetate component is larger than the above ratio, the occurrence of crimp is suppressed and the bulging feeling is reduced.

ができる。The alkali treatment is carried out, for example, by using an alkali compound such as sodium hydroxide, potassium hydroxide or calcium carbonate, and immersing the precursor fiber in a solution of the alkali compound and impregnating it with padding or the like. The treatment liquid concentration, treatment temperature, and treatment time in alkaline treatment are
Depending on the alkali compound used and the intended product, the preferred alkali treatment conditions are as follows. When an aqueous sodium hydroxide solution is used, the concentration of sodium hydroxide does not exceed 5% by weight, and the treatment temperature is 30 to 100.

よりふくらみ感を奏する。Although the precursor fiber is affected by alkali treatment and deacetylated, cellulose triacetate in each composite component is hardly affected, and the cellulose diacetate susceptible to alkali treatment is reduced. At the same time, it is converted into cellulose acetate having a low acetylation degree or further converted into cellulose to be an acetate conjugate fiber having a relatively increased proportion of cellulose triacetate. Further, due to the difference in the influence 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 crimp property as described above. A feeling of swelling is achieved by improving the bulkiness.

となしうる。In general, cellulose triacetate fibers having a high degree of acetylation have low water retention ability, but the acetate conjugate fibers of the present invention obtained by alkali treatment of precursor fibers having a specific composite structure are cellulose or average acetylated. Since cellulose acetate having a degree of less than 48.8% is present on the side surface of the fiber, it is possible to obtain a fiber having improved water absorption and hygroscopicity despite the large amount of cellulose triacetate component.
