The commercial polyester and polyester-mixed woven fabrics were dry-cleaned using perchloroethylene (D-treatments). The changes of physical properties of the fabrics by D-treatments were compared with those treated with water (W-treatments).
Both D- and W-treatments tended to increase the elongation percentage and the compressibility ratio and to decrease the bending resistance and the compressional resilience for the fabrics. Wtreatments led to the larger changes in physical properties than D-treatments did. It was assumed that the plasticization of the polyester fibers took an important role in the difference of the property-changes.
The difference of properties of the fabrics D-and W-treated was studied in connection with the structural factors of the fabrics using multi-variate analysis. It may be noted that the factors were less related to the bending resistance which was highly significant with respect to the difference between the population means. The composition and nonuniformity of the fabrics affected the difference of the property-changes. It was found that the crimp retraction of the weaving yarn was closely connected with the elongation percentage and the air permeability of the fabrics. The twist coefficient of the yarn was also found to be associated with the compressional resilience of the fabrics.
