することができるからである。In the present invention, it is necessary that the polyester fiber has an irregular uneven surface, and has fine pores communicating with the air-permeable portion from the surface. In order to form an uneven surface, a method of roughening by rubbing with abrasive powder or a method of etching the fiber (for example, in the case of polyester fiber, a method of expressing the uneven surface by alkali treatment with caustic soda) ), Or a method in which a substance capable of being dissolved and removed in a later step is mixed and spun, and then a component other than polyester is extracted and removed to obtain an uneven surface. Of these methods, the method of alkali treatment is preferably used in the present invention. This is because the hollow fiber used in the present invention has a large hollowness as compared with the conventionally manufactured hollow fibers, and therefore the polyester fiber portion has a large surface area and the sheath portion has a small thickness. Easily susceptible to erosion, so in the case of ordinary non-hollow polyester fibers, even if fine irregularities are formed on the fiber surface by alkali treatment with caustic soda, fine pores do not penetrate in the fiber cross-sectional direction. In the case of the ultra-hollow fiber having a hollowness of more than 30% as in the present invention, a part of the hollow part is intensively eroded by the above-mentioned erosion processing, and the micropores are easily removed from the fiber surface to the inside. This is because it is possible to penetrate to the hollow portion.

中空度の中空繊維を製造することができる。In the production of ultra-hollow fibers, a method which is essentially conventional has been generally adopted. For example, in FIG.
As shown in (b), the polymer is ejected from a slit-shaped nozzle that divides the circle into 3 or 4 parts, and the part that is not joined at the time of ejection is joined within a few cm directly under the spinneret due to the polymer dispersive effect. In this way, while cooling the surface by the air flow to the hollow fiber surface, an inert gas such as nitrogen gas is introduced into the inside of the slit nozzle, and the cooling from the inside of the fiber by the inert gas is cooled from the surface. The hollow fibers can be produced at the same time, and in this way, hollow fibers having a hollowness of 30% or more can be produced.

方向に微細孔が貫通することはない。In the case of the polyester fiber represented by polyethylene terephthalate, the intermolecular force is weak because it is only the Van der Waals force as inferred from the molecular production, and in particular, in the case of the ultrahollow fiber of the present invention, The intermolecular force of the part to be joined immediately after coming out of the nozzle is weak, and this part is intensively eroded during erosion treatment such as alkali treatment. In the case of an ultra-hollow fiber with a hollowness of 30% or more, it is natural that the sheath portion is thin and erosion can reach the inside of the hollow relatively easily. At this time, the micropores in the sheath portion penetrate from the surface of the sheath to the inside of the hollow portion. When the surface of the hollow fiber thus obtained is observed by a scanning electron microscope, the minor axis 1 to 3 μ and the major axis 1 to 5 are observed on the surface.
An elliptical unevenness of μ was recognized, and further, in the longitudinal direction of the fiber, some of the above-mentioned elliptical unevenness was extremely long, and the length reached several tens of μ. What is observed is observed. In the case of ordinary polyester fibers, the alkali treatment only causes irregularities with a minor axis of 0.5 to 3 µ and a major axis of 1 to 5 µ, and fine pores do not penetrate in the cross-sectional direction of the fiber.

As the hydrophilic resin used here, polyvinyl alcohol, polyvinylpyrrolidone, polyacrylic acid, sodium polyacrylate, carboxymethyl cellulose, polycondensation product of polyalkylene glycol and terephthalic acid, etc. Any resin can be used as long as it has a polar group such as an amide group and a carbonyl group. Among them, in the case of the present invention, from the viewpoint of the affinity between the fiber and the resin, the weight of polyalkylene glycol and terephthalic acid is increased. Condensates are preferably used.

きる。In order to apply the hydrophilic resin to the woven or knitted material, a method of heat-treating the solution of the resin after padding or a method of dipping and exhausting with a dyeing machine is adopted, but the point is that the inner surface of the hollow part of the fiber is It is important to attach the hydrophilic resin, and for that purpose, for example, it is preferable to perform the treatment at a treatment temperature of 100 ° C. or higher for 10 minutes or longer. From this point, the simultaneous exhaustion method at the time of dyeing by a jet dyeing machine, a high-pressure jigger, or a beam dyeing machine is often used advantageously. Further, in the case of the padding heat treatment method, if the surface tension of the treatment solution is lowered by adding a surfactant or a lower alcohol to the resin solution in advance so that the fiber is easily wetted, the inner surface of the hollow portion of the fiber is It is possible to easily attach the hydrophilic resin to the.

が生かされていた。(Working) The water-absorbent woven or knitted fabric of the present invention is composed of fibers having a hollow cross section with a hollowness of 30% or more, and by the erosion processing of the fibers, it has fine pores communicating from the fiber surface to the hollow part and is hydrophilic. By applying the resin, a hydrophilic resin is adhered to the inner surface of the hollow portion of the fiber. In the case of the present invention, since the hydrophilic resin is applied to the inner surface of the hollow portion in this manner, unlike ordinary polyester fibers, not only the wetting property by the hydrophilic resin is improved but also the hollow portion of the fiber is improved. It became possible to keep water in.
This was confirmed by dropping water on the above fibers under an optical microscope and observing the movement of water. In addition, the polyester fiber with a hollow cross section with a hollowness of 30% or more,
The hollows were hardly destroyed even by the erosion treatment, and therefore the hollow-type characteristics were utilized in terms of weight saving and heat retention of the fibers.
