Moreover, the velvet obtained in the example 2 is short and dense, has fluffy and soft hand feeling, and has no fuzzing phenomenon on the surface of the fabric, and the velvet obtained in the comparative examples 2 and 4 is short and sparse and has smooth hand feeling.
Comparing the test results of example 4, comparative example 3 and comparative example 5, it can be seen that when the softening agents PEP and AS-23N, BS-04L are respectively used in amounts of 2%, the anti-pilling grade of the velvet cloth obtained in example 4 is obviously higher than that of the velvet cloth obtained in comparative examples 3 and 5, the charge surface density of the velvet cloth obtained in example 4 is obviously lower than that of the velvet cloth obtained in comparative examples 3 and 5, and the thermal resistances of the velvet cloth and the velvet cloth are not greatly different. In addition, the velvet obtained in example 4 is short and dense, has a fluffy and soft hand feeling, and has no fuzzing phenomenon on the surface of the fabric, and the velvet obtained in comparative examples 3 and 5 is long and dense and has a smooth hand feeling.
In conclusion, when the PEP softener is adopted in the softening liquid in the process of softening and shaping the grey cloth, and the mass percentage concentration of the PEP softener is controlled to be 2%, the obtained velvet is short and dense, the hand feeling is fluffy and soft, the surface of the fabric has no fuzzing phenomenon, the anti-pilling grade is high, and the antistatic effect is excellent.
