It was the actual situation. In order to improve this, a means for imparting hygroscopicity by graft-polymerizing acrylic acid or methacrylic acid to synthetic fibers described in JP-A-61-282476 and the like, and JP-A-61-266672 are disclosed.

In the method in which acrylic acid or methacrylic acid is graft-polymerized to synthetic fibers, it is necessary to perform graft polymerization before the dyeing process due to the nature of the polymerization initiator used. Is inevitable. Further, in the method of providing a hygroscopic substance such as cellulose or polyamino acid resin to a synthetic fiber cloth or a yarn, it is difficult to obtain a sufficient hygroscopic performance from a balance with a texture, and an object of the present invention. It cannot be clothing with excellent wearing comfort. In addition, when a polyamino acid-based resin is applied to the yarn, it is a fatal disadvantage that the alkali weight loss texture, which is a characteristic of polyester, cannot be obtained.

From the viewpoint of preventing a decrease in the durability of the film due to a decrease in the molecular weight of the copolymer, 0.1% to 3% is preferable. In addition, when the total monomer concentration in the monomer and the polymerization initiator is increased, the polymerization may occur in the state of a mixed monomer aqueous solution. In this case, it is preferable to add an appropriate amount of a polymerization inhibitor in order to increase the stability of the mixed monomer aqueous solution and prevent the durability of the coating film from decreasing. Preferred as the polymerization inhibitor is a water-soluble polymerization inhibitor such as sodium nitrite, and the necessary addition amount is 0.01 to 0.3%. In general, the concentration of the polymerization initiator and the polymerization inhibitor can stably maintain the aqueous solution of the mixed monomer at about 40 ° C. for about 12 hours.

分である。In the present invention, in order to accelerate the copolymerization reaction, it is also preferable to heat the cloth after applying the mixed monomer aqueous solution to the cloth.
Steam heating such as normal-pressure steam, heating steam, and high-pressure steam is adopted. If the drying heat is used irrespective of steam, a uniform copolymer film along the fiber axis cannot be obtained, resulting in problems such as poor durability of the polymer and hardening of the hand. From the viewpoint of obtaining a uniform copolymer film, the steam heating temperature is preferably from 80 to 180C, more preferably from 100 to 160C. When the steam heating temperature is 100 ° C. or higher, heating for 1 to 8 minutes is sufficient.

It is also preferable to use high-frequency heating in combination with steam. High-frequency heating is to generate heat by applying high-frequency waves of 2450 MHz and 920 MHz to an object to be heated, and is generally used in combination with normal-pressure steam. As such heating equipment, there are a normal-pressure steamer, a pressurized steamer, and a high-frequency heater equipped with a high-frequency oscillator in these steamers. A high-temperature steamer, which raises the temperature by sending hot air into a normal-pressure steamer, can also be applied as long as the above temperature condition is satisfied. In this case, it is preferable to use as much steam as possible in order to obtain a copolymer film.

If the dried state is not passed after the copolymerization reaction, there is a problem that when the object to be treated is immersed in water, the copolymerized polymer film swells with water and easily falls off in the washing step. Although the cause is not clear, it is considered that the crosslinking reaction proceeds by drying to form a strong copolymer film.
