求翻译：乳胶膜的吸水率从17%下降至6%，接触角从30.3°提高至75.7°，耐热性得到提高；改性后水性聚氨酯微观形态较规整。是什么意思？

Water absorption of latex films decreased from 17% to 6%, the contact angle increased from 30.3 ° to 75.7 °, heat resistance is improved; modified polyurethane morphology more regular.

Latex membrane water absorption rate dropped from 17 per cent to 6 per cent, the contact point from 30.3 degrees to 75.7 degrees, heat-resistance are enhanced; after living modified organisms polyurethane micro patterns of water is more than the whole.

The young cellophane water-absorptivity from 17% drop to 6%, the angle of contact from 30.3° the enhancement to 75.7°, the thermal stability obtains the enhancement; After the modification the river character polyurethane microscopic shape is neat.

Latex film water absorption rate fell from 17% per cent, from 30.3 ° up to 75.7 ° contact angle and heat improved; after the modification of waterborne polyurethane morphology more structured.

The water absorbing capacity of the membrane of emulsion drops from 17% to 6%, exposed to the angle to raise from 30.3 degrees to 75.7 degrees, heat resistance is improved; The micro shape of polyurethane of swimming skill is relatively advised wholly after modifying.
