The resulting composite fiber is hydrophobic. Hydrophilic composite fibers have also been proposed, but they have not yet been put into practical use because they are difficult and costly to manufacture.

ーは市場で安価に入手できるので都合がよい。The present invention is a polyolefin polymer with MFRIO~100
Consisting of A component and B component with EvOH Te MFR 20 to 100, ethylene content 20 to 45 mol%, and saponification degree of 98% or more, at least one component of both A and B components is 2 or more in the fiber cross section. Each unit is a constituent unit of the fiber cross section, and each unit is adjacent to a constituent unit of a different component, and each constituent unit has a part exposed to the fiber surface. The polyolefin used as component A includes polypropylene and polyethylene. These polyolefins have low compatibility with EvOH, and therefore have good splitting properties as conjugate fibers, and can be spun at a relatively low melting temperature, so conjugate fibers can be produced with good process efficiency within the temperature range at which EVOH can be spun. Moreover, these polymers are conveniently available in the market at low cost.

下し本発明の目的に合わない。The EVOH used as component B must contain 20 to 45 mol% of ethylene; if it is less than 20 mol%, the spinnability will be significantly reduced and continuous spinning will be difficult. 45 again
If it exceeds mol%, spinnability is good but hydrophilicity decreases, which is not suitable for the purpose of the present invention.

~45 mol% is used. EVOH can be obtained by saponifying a copolymer of ethylene and vinyl acetate.
The degree of saponification is desirably 98 mol% or more from the viewpoint of spinnability.

ら１＝５〜５：工程度が適当である。In the composite fiber of the present invention made of such components, in its cross section, at least one of the A and B components is divided into two or more constituent units and arranged so as to be adjacent to each other and the other components. Of course, each constituent unit is continuous in the length direction of the fiber. A portion of all the structural units appears on the fiber surface. The composite ratio of both components A and B can be changed depending on the desired performance. When improving hydrophilic performance, there is no particular restriction on the proportion of the 0-picture component that increases the EVOH ratio, as long as the amount of one component can divide the other components into at least two parts. Also, A on the fiber surface,
The ratio of both components B is not particularly limited, but from the viewpoint of workability in the spinning process, a ratio of 1=5 to 5:process ratio is appropriate.
