A fiber consisting essentially of polyethylene terephthalate capable of being dyed under normal pressure and having an initial modulus at 30.degree. C. of about 55 g/d to about 130 g/d, a relationship between a peak temperature [T.sub.max (.degree.C.)] at the peak of a dynamic mechanical loss tangent (tan .delta.) measured with a frequency of 110 Hz and a peak value of the dynamic mechanical loss tangent [(tan .delta.).sub.max ] represented by the formula:

Vegetable beverages are clarified or stabilized by using an adsorbent material consisting essentially of a specified N-substituted polyamide or polyamide mixture. The specified polyamide is such that 0.5% to 65% in number of the hydrogen atoms linked to the nitrogen atoms of the amide linkages in the main chain are substituted with substituents represented by the formula
