How much softener is generally appropriate to add to high-strength sewing thread?
Basic dosage: Taking amino silicone oil as an example, when formulating with high-molecular-weight silicone oil, adding 0.1% to 5% is sufficient to balance efficacy and emulsifiability.
The recommended dosage of softening agents added to high-strength sewing thread is 0.1% to 5%. The specific dosage should be adjusted based on the following factors:
Basic dosage: Taking amino silicone oil as an example, when formulating with high-molecular-weight silicone oil, adding 0.1% to 5% is sufficient to balance efficacy and emulsifiability.
Performance requirements:
If you need to improve smoothness, you can use a hydrogen-containing silicone oil formulation to enhance durability.
To meet antistatic requirements, polyether-modified silanes can be added.
Process Compatibility: For high-temperature processing (such as false twisting), it is essential to select oil agents with excellent heat resistance to prevent decomposition and subsequent performance degradation.
In practical applications, it is recommended to determine the optimal ratio through small-scale testing.
