Performance detection
Performance detection is carried out to the polyester staple fiber product of embodiment 1-3 and comparative example, the boiling water that emphasis detects product is received
Shrinkage, detection method is referring to national standard GB/T6505-2001《Filament of synthetic fibre heat shrinkage test sheet method》, by defined
The length of test sample before and after the processing calculates boiling water shrinkage under the conditions of pre-tension, according to formula S={ (L0-LS)/L0*
100% } boiling water shrinkage is calculated, wherein L0 is initial length, and LS is length after shrinking, can in order to improve accuracy and data
By property, each embodiment takes three samples to measure, and is averaged.
Testing result is referring to the following table 1：
| Embodiment 1 | Embodiment 2 | Embodiment 3 | Comparative example | |
| It measures for the first time | 1.15% | 1.16% | 1.11% | 1.58% |
