Description

Binder paste having moisture-absorbing, antibiotic and deodorizing function and socks comprising the binder paste}

The present invention relates to a binder paste having a hygroscopic, antibacterial and deodorizing function and a sock having an athlete's foot restraining function to which the binder paste is applied. More specifically, the present invention is a binder paste having a hygroscopic, antibacterial and deodorant function including an inorganic hygroscopic antimicrobial agent, a microencapsulated deodorant, a thickener, and the like based on a polyurethane, and a sock having an athlete's foot inhibiting function to which the binder paste is applied. It is about.

Often, after wearing socks, the odor that soaks in socks is caused by sweat and organic matter such as proteins and fats released from the feet, and waste products such as the stratum corneum from the feet. It is mainly due to the soaking and decay of these moisture and organic matters as waste products by the propagation activity of bacteria such as dermatophytes.

As a conventional sock for solving such a problem, for example, the antibacterial agent containing chitosan is printed on a transfer sheet, and then the transfer sheet is manufactured to have an antibacterial power by a thermal transfer printing method with a constant printing pattern on the bottom of the sock.

However, these conventional antimicrobial thermal transfer printing socks have some degree of antimicrobial activity in the early stage, but it is weakly deodorant and does not completely eliminate foot odor. It was weak and easily exhausted and had a problem of poor elasticity.

In addition, there is a sock in which a binder paste containing inorganic oxide powder such as ganban stone or ceramic is applied to the bottom of a sock in a sol polyvinyl chloride resin, but an organic solvent DOP (Dioctyl Phthalate) for handling polyvinyl chloride resin is As it is harmful to the drug, its use is not desirable, and its use is strictly restricted in some countries such as the United States, and polyvinyl chloride resin (PVC) has almost no moisture permeability due to its almost no moisture permeability. There is a problem that is used extremely limited for non-slip socks for children.

Therefore, much effort is still being put into the production of socks which are innocuous to the human body, such as giving the socks a deodorant or deodorizing function, and suppressing the growth of bacteria that cause foot odor.

In particular, the development of a binder paste with excellent binding strength in printing (inner) is still insufficient, and therefore, there is a desire to develop a binder paste having excellent binding strength and a sock having an athlete's foot suppressing function.
