Description

The present invention relates to a fiber treatment composition. More specifically, the present invention relates to a fiber treatment composition which has excellent appearance stability, excellent adsorption of an ultraviolet absorber to a textile product, and can impart moisture diffusibility to the textile product.

In recent years, the number of UV care products has increased due to an increase in health consciousness such as whitening needs and interest in sports, and in the textile industry, the number of fiber products having an UV protection effect has also increased. This fiber product can exert an ultraviolet ray protection effect in the skin area which is difficult to deal with with a sun screening agent or a parasol which is directly applied to the skin.
As a means for imparting an ultraviolet protection effect to a textile product, a treatment using a fiber treatment agent containing an ultraviolet absorber is known (Patent Documents 1 and 2).

JP, 2009-7731, A JP 2002-161476 A

However, the present inventor has found that conventional fiber treatment agents containing an ultraviolet absorber have problems in appearance stability and adsorption of the ultraviolet absorber to a textile product.

The present inventor, as a result of diligent studies on the above problems, found that the above problems can be solved by adding a specific amount of an ultraviolet absorber having a specific structure to a fiber treatment agent, and further, high moisture diffusivity can be imparted to a fiber product. .. The present invention has been made based on this finding.

When the degree of cationization is within the above range, it is possible to further enhance the adsorptivity of the coexisting component (B) to the fiber product, and prevent an increase in cost due to a large amount of compounding.

The degree of cationization is such that the component (A) is a polymer of (i) a cationic monomer, (ii) a copolymer of a cationic monomer and a nonionic monomer, or (iii) a part of the nonionic polymer is a cationic group.

Z: 2.78×10 ⁻³ (weight of 1 g of anionic group: 0.2 g, calculated from molecular weight of anionic group)
From the formula (2), the cationization degree (%)=
^{14 × (4.95 × 10 -3 -2.78} × 10 -3) is × 100 = 3.0.
