The present invention provides a process for surface modification treatment of a polymer, and products produced therefrom, in which a polymer is subjected to a surface modification treatment using a sulfuryl chloride (SO2Cl2)-based solution, followed by employing a reaction terminating agent capable of decomposing or neutralizing sulfuryl chloride to terminate the surface modification treatment. A thus-obtained polymeric fiber or fabric exhibits excellent properties, such as moisture diffusion and wicking properties, anti-pilling property, dyestuff dyeability and the like.

1) Field of the Invention
The present invention relates to a process for surface modification treatment of a polymer, and products produced therefrom. Specifically, according to the present invention, a polymer is subjected to a surface modification treatment using a sulfuryl chloride (SO2Cl2)-based solution, thereby improving the surface properties thereof, such as the dyestuff dyeability of a polymeric product, the moisture diffusion and wicking properties, the anti-pilling property and the full-dull property of a polymeric fiber or fabric, etc.
Influences of Reaction Temperature and Reaction Time of the Surface Modification Treatment upon the Burst Strengths of Polymeric Fabrics
The surface modification treatment is conducted according to the following operating procedures in sequence:
(a) subjecting five samples of identical PET knitted fabrics (Topcool fabrics made of yarns of special cross section, manufactured by Far Eastern Textile Co., Ltd., fiber fineness 1.3d/f) to a surface modification treatment by respectively immersing the same into a solution of sulfuryl chloride, wherein the respective reaction temperature and reaction time for each of the five samples are listed in Table 1;
