Most preferably, the normally-soaked sock of step (b) may be dried at 50-70 degrees Celsius using a rotary dryer.

In the present invention, the normal washing treatment and the tumble washing treatment are very important constitutions. This is because the size of the intermediate sock manufactured through the sock knitting machine can be reduced through the normal washing and the dumbbell washing process, and the increased sock size can be restored to the original reduced size through the washing process.

It seems that the sock size reduced by the normal washing process is fixed by the dumbbell washing process.

According to a preferred embodiment of the present invention, the foot length of the stretchable sock for infant and child in the step (c) of the present invention is such that the foot length of the intermediate sock of the step (a) may be 40-60% less as compared to the footstep of the intermediate step socks during the tumble wash process of step (c).

In the present invention, it is a very important constitution that the leg length of the stretchable sock for infants and children is reduced to a length of 賊 10% of the leg length of the intermediate sock. This is because if the size of the intermediate sock is made to be No. 6 (see Table 1 below) when length contraction occurs in the range of the sock length described above, the size of the sock is reduced to the size of the newborn sock by the washing process and the dumbbell process Because of a pair of socks, it is possible to wear socks from newborn to 5 to 10 year olds.

According to a preferred embodiment of the present invention, the footstep of the stretchable sock for infants and toddlers of the present invention may preferably be reduced to ± 10% of the original footstep when washing, even if the footstep is increased by wearing.

In the present invention, even if the leg length of the stretchable sock for infants and toddlers is increased due to wear, it is a very important constitution to reduce the leg length of the stretchable socks to 10% of the original leg length. This is because if you do not get back to your original size after washing your socks by wearing socks, you will not be able to function as socks that can be worn by infants of all ages.

According to another aspect of the present invention, there is provided a method of manufacturing a stretchable sock for infants and children by reducing the length of the knitted sock by subjecting the knitted sock to a normal washing treatment and a tumble washing treatment, The stretchable sock provides a stretchable sock for infants and children that is reduced by 40-60% compared to the length of the knitted sock.

According to a preferred embodiment of the present invention, the foot length of the stretchable sock for infants and children of the present invention may preferably be reduced to ± 10% of the original foot length even when the foot length is increased by wearing.

In the present invention, the matters relating to the stretchable socks for infants and toddlers are common to the above-described method for producing stretchable socks for infants and children, so that the description thereof will be omitted in order to prevent the present invention from being excessively complicated.
