０８１号、特公昭６３−２４１１６号）。<Prior art> Sanitary materials such as disposable diapers and sanitary products cover highly water-absorbent fibers such as bulbs, rayono cotton, and absorbent cotton with hydrophobic fibers. There is a well-known technology that, through treatment, prevents the waste fluid absorbed by the absorbent material from flowing back through the face cover and provides good skin texture (Japanese Patent Publication No. 63-14).

。In addition, heat-sealable conjugate fibers are increasingly being used in phantom materials for sanitary materials. For example, in the case of disposable diapers, leakage has been prevented by improving the fit by using a geared structure at the waist and legs or by using stretchable materials such as polyurethane. It also uses a highly water-repellent non-woven fabric made from heat-sealable composite fibers to further strengthen its leak-proof properties.

みられてきたが工程か煩雑となる欠点を有していた。As a method of imparting water repellency to textile products such as textiles,
Conventionally, water-repellent treatment with silicone-based or fluorine-based water-repellent oil agents has been carried out, but the water-repellent properties of non-woven fabrics can also be improved by one treatment with water-repellent oil agents during the manufacturing of non-woven fabrics, similar to conventional back-processing. is granted. These water-repellent oil agents eliminate the trouble of electricity generation from raw cotton, making it difficult to pass through the process! was there. In order to suppress such static electricity troubles, attempts have been made to add static electricity suppressants to the process, but these have had the disadvantage of complicating the process.

つた。In addition, even if a conventionally known cationic oil agent with high antistatic ability is used in combination with a water-repellent oil agent to suppress static electricity troubles and improve process passability, the water-repellent performance may deteriorate. An unusual phenomenon was occurring. Furthermore, when using a fluorine-based oil as a water-repellent oil, there are problems such as the oil is very expensive, and the inertness of the fluorine itself reduces the strength of the nonwoven fabric and becomes an impediment to thermal adhesion.

に到達した。<Means for Solving the Problems> As a result of intensive studies to solve the above problems, the present inventors treated heat-sealable composite fibers with a specific oil agent to reduce the amount of adhesion from 0.1 to 0.01.
The inventors have discovered that by adjusting the amount to 2% by weight, it is possible to obtain a heat-sealable conjugate fiber that has excellent process passability, exhibits good water repellency without post-processing, and has a soft texture, and has thus arrived at the present invention.

B)/(C) is 50,150 to 70/30, preferably 55/45 to 65/35. When (B)/(C) is less than 50,750, static electricity problems are likely to occur during the manufacturing process, and when it exceeds 70/30, water repellency decreases and fiber entanglement property decreases when made into a nonwoven fabric. So I don't like it. Also, (A)/((B)+(C)) is 5

+5/85. If it is less than 5,795, the water repellency will be poor, and if it exceeds 20,780, static electricity problems will increase during the manufacturing process, which is not preferable.

A water-repellent heat-sealable composite fiber having excellent process passability, good water-repellent performance, and soft texture can be obtained. The fibers are suitable, for example, as nonwoven fabric materials for sanitary materials such as disposable diapers and sanitary products. If the amount of adhesion is less than 0.1% by weight, good water repellency will not be exhibited, and if the amount of adhesion exceeds 2% by weight, there will be poor permeability in manufacturing processes such as spinning.

った。As a result, in the present invention shown in the examples, the water repellency was 70% or more in all cases, and the process passability was also good.
Moreover, the texture of the obtained nonwoven fabric was also extremely soft.

過性不良もしくは撥水性不良の現象がみられた。For comparison, the amount of oil adhered is 0. ] Less than % by weight (
Comparative Example 1) has poor water repellency. If the amount of adhesion exceeds 2% by weight (Comparative Example 2), poor entanglement properties and poor winding process properties tend to occur during the spinning process and the like. Next, composite fibers treated with oils with different oil compositions and blending ratios (
As a result of evaluating Comparative Examples 3 to 9), phenomena of poor process passability or poor water repellency were observed in each of them.
