In this paper, the influence of pre-tension on elongation percentage at specified load for knits was studied .First of all, initial elongation and elongation percentage at specified load for different retractility knits were tested and analyzed at different pre-tension. And then significance of influence of pre-tension on initial elongation and elongation percentage at specified load for knits were analyzed by means of variance analysis. Results show that the pre-tension has significant influence on initial elongation for different retractility knits, and it has no significant influence on elongation percentage at specified load for little retractility knits, and it has significant influence on elongation percentage at specified load for well retractility knits. The greater the pre-tension is, the more significant the influence is, Therefore it is suggested that pre-tension is generally less than 0.1N in the test.The research results can provide a certain reference to stretch and recovery test for knits and test standard recension .
