Abstract
The present invention provides a fiber-treating agent which contains a chitosan zirconium salt obtained by ionically bonding chitosan with a zirconium salt. By treating fibers with this treating agent, chitosan can be ionically bonded to the fibers. The fibers thus treated have the high ability to hold the chitosan fixed thereto and have satisfactory antibacterial and heat-reserving properties imparted thereto. These effects are maintained for long even when the fibers are repeatedly laundered.
Description
Technical field
The fiber-like that the present invention relates to contain the shitosan zirconates is with finishing agent and the fiber-like that makes quality obtain improveing by the ions binding shitosan.
Background technology
The good hand touch of fiber has become important mass property, and feel is relevant with the heat insulating ability of fiber.In the past, adopt following method to make thermal insulating fibre, these methods are, the occasion of synthetic fiber makes hollow to fiber and makes good adiabatic function, or sneak into method such as pottery; And the occasion of natural fabric then has the method for using resin to adhere to processing ceramic etc.
Yet, exist from throwing time-consuming long to being processed into fibre, incompatible problem with the demand in market with such method.In addition, even only from quality, the occasion of doughnut has said bending property difference and the shortcoming that bends, make resin attached on the natural fabric with the occasion of ceramic set, even heat insulating ability is arranged, but also hardening of feel, existing problems aspect design.
Recently, the shitosan of chitinous deacylation thing is subjected to people's attention, and expectation comes endowing antibacterial and improves feel by contain it in fiber.In the past, there were following 2 kinds as what technology in the fiber that shitosan is fixed in had been known.
The first is sneaked into the method for fibrous inside to shitosan, has suppressed coming off of shitosan thus.But this method can not be suitable for natural fabrics such as cottons technically, is to be object with special fibers such as polyester or artificial silks.And, because this method of sneaking into is sneaked into fibrous inside to shitosan, thereby does not have too many shitosan to expose at the surface portion of fiber, therefore almost can not expect to have the effect of antibiotic property.
Another is the method for Low Temperature Heat Treatment, thinks to its objective is by with shitosan Low Temperature Heat Treatment fiber simply, makes it be fixed in fiber surface, also can be suitable for for natural fabric.But, owing to only simply at low temperatures shitosan is fixed, thereby have the shortcoming that will come off through 4～5 times washing.Usually, clothes for example is the occasion of object with the underwear, if minimum can washablely just have practicality more than 50 times.
As mentioned above, although, antibacterial effect cheap from shitosan, the utilization of expectation in fiber,, actual conditions are also not develop the high technique for fixing of practicality so far.
Summary of the invention
