OBJECTIVETo provide experimental proof for establishing a standard quality evaluation method of adhesive property on Cataplasma by studying the factors of effect on evaluation of adhesive quality on Cataplasma.

METHODWith 180 degrees peel off test, tensile shear and adhesive force test, the influence caused by the square of samples, texture of fabric base and the moisture loss was tested with multifunctional material tester and first stickiness tester.

RESULTThe peel off strength of 40 mm wide sample is 26% lower than that of the 20 mm wide sample (P < 0.05), and tensile shear strength had no significant difference. The peel off strength of transverse fabric base was higher than that of lengthways fabric base (P < 0.01). The tensile shear strength of transverse fabric base was lower than that of lengthways fabric base (P < 0.05). The sample with 35% moisture lost had a maximum tensile shear strength and the sample which lost 30% moisture lost had a maximum peel off strength; The sample which lost 20% moisture lost had a maximum first adhesive force.

CONCLUSIONThe square of samples, the texture of fabric base and the moisture loss of samples can all affect the evaluation of adhesive quality on Cataplasma.
