Study on elastic recovery percentage improvement of polyether ester elastic fiber with organic nucleating agent;

And it was found that these factors have no significant influence on the elastic recovery percentage of the floss silk,whereas the softener has significant influence.

The relationship between their elastic recovery ratio and times by the resilient-elasticity recovery at constant elongation testing was analyzed.

In this thesis,the properties involved elastic recovery ratio,curling tendency,shrinkage in boiling water of PTT were tested.

Influence on the elastic recovery rate adding Re and Zr in the CuAlMnZn shape memory alloy;

This paper based on drape coefficient test,and gram test of seven common-used knitted fabrics and also tested tensile force,elastic recovery rate,the rate of plastic deformation,stress relaxation rate under conditions of tensile elongation.

The following things were found out by comparing measured results: The lowest modulus and highest elongation recovery ratio can be offered by PTT, the modulus of PA66 is higher than PTT and PBT, and its elongation recovery ratio is lower than PTT and PBT, the modulus and recovery ration of PBT is between PTT and PA66, Lycra has the longest elongation but the core-spun yarn with Lycra .

By adding the trifunctional ester crosslinking agent of right amount into polyetherester and adjusting the conditions of drawing process, the elastic recovery of polyetherester elastic filament (TPEE) can be improved.

The test results showed that PTT fiber owns good elastic recovery,and the crimping capacity and the boiling-water shrinkage property of PTT/PET and PTT/PBT were better.

Stretching and elastic recovery properties based on elongation of three kinds of PTT (Polytrimethylene terephthalate)/PET (Polyethylene terephthalate) self-crimping filaments with same linear density were tested.
