But the cotton fabrics treated by PVA must be desized to enhance their waterabsorbency.
经pva上浆的棉织物必须经过退浆处理,以增加棉织物对水的吸收性。
2
The waterabsorbency was descended with the ascending of the concentration of the external ion solution and the valence of the ion.
实验结果表明:随着外部盐溶液浓度的增大及盐离子的价态的升高,复合材料的吸液率下降;

The results showed that the terpolymers possessed good emulsifying property and waterabsorbency , and behaved as thermoplastic elastomers according to their composition.
