A product for incorporating ultraviolet radiation protection and antimicrobial protection into a synthetic polymer prior to forming a synthetic material is also disclosed which has a quantity of synthetic polymer chips and a quantity of zinc oxide particles modified with a layer of a reactive group that forms a bond with the quantity of the synthetic polymer chips.

The toy product of the present invention incorporates an antimicrobial agent that is introduced during the manufacturing process, to render the resultant product hypoallergenic and resistant to stains and odors during use, even after repeated washings.

In a preferred embodiment, the toy product is a stuffed plush animal in which some or all of the yarn/fabric used in fabricating the toy product is treated with an antimicrobial agent during the knitting or weaving of the yarn to create the plush. While many different antimicrobial agents may be used, a preferred microbial agent is a solution containing silver nitrate, silver chloride, and/or alkyl dimethyl benzyl ammonium chloride.

The disclosure discloses a method for anti-felting finishing of wool fabric with protease K, and belongs to the technical field of dyeing and finishing of wool fabric in the wool spinning industry. The purpose is to solve the problems that common protease anti-felting treatment has greater damage to the strength of wool and has a weak degradation effect on keratin in a scale layer, thereby achieving the purpose of optimizing the anti-felting finishing of wool fabrics with protease. A preferred process is: pure wool fabric is first pretreated with urea peroxide, CMC is blocked with chitosan oligosaccharides, and then the wool fabric is treated with protease K. The wool fabric treated by the method has obviously improved anti-felting property, and the damage to the strength of the fabric is reduced. The disclosure introduces protease K into the anti-felting finishing of wool for the first time. Through effective degradation of keratin in wool scales by the protease K, a good anti-felting effect of wool is achieved, and the protease K anti-felting treatment can replace the traditional chlorination anti-felting treatment.
