First clarify the fibers, fabrics and finishing stages
Cotton, synthetic fibre and blended fabrics are equipped with antibacterial finishing according to dyeing, softness, waterproofing and post-processing processes. Engineers select dye vats, dip-bath treatment or spray routes based on fibre, colour and auxiliaries, and provide corresponding liquid preparation and cloth loading.
Three types of finishing raw materials are selected separately
| Organize direction | Specific model | Supporting technology |
|---|---|---|
| organosilicon quaternary ammonium compound finishing | AEM5700 | Fabric pretreatment, auxiliary ionicity and co-bath arrangement |
| Silver ion finishing | AEM5700-A05 | Colour, formula compatibility and post-wash requirements |
| biguanide finishing | AEM5700-MB20 | Dyeing and finishing, dip-bath treatment or spray route and actual cloth volume |
working solution concentration and actual cloth volume are calculated separately
After dip-bath treatment, the wet pickup is calculated based on the difference between the wet weight and the original dry weight, and then combined with the working solution concentration to calculate the amount of agent applied. We provide liquid preparation suggestions based on the fabric and pressing conditions, record cloth weight, bath liquid and drying process, and provide finishing and development services.
Same bath compatibility and drying are implemented according to the model
AEM5700 and anionic finishing agents are used in separate baths; cationic or non-ionic finishing agents are used in the same bath for compatibility. A05 and MB20 are respectively equipped with model processes, connecting liquid removal, drying and colour and feel evaluation.
Finished fabric and post-wash functional evaluation
We use the finished finishing cloth and the control cloth from the same batch to conduct antibacterial evaluation, and compare the pre-wash and post-wash conditions according to the corresponding washing methods; the anti-mould function is evaluated using an independent material culture project.

Frequently asked questions
What does 5% bath liquid mean? Does the cloth weight also add 5%?
These quantities use different measurement bases. Calculate the chemical add-on to the fabric from the actual wet pickup and bath concentration. Record wet pickup again when the fabric or padding conditions change.
Can I bathe it directly with existing softener?
First check the ionicity and compatibility of the additive. AEM5700 uses a separate bath arrangement for the anionic system; other models are also tested for compatibility with existing softness, waterproofing and other additives.
Can the same liquid preparation conditions be used for spraying and padding?
Spraying is based on coverage and application amount, and padding is based on wet pickup to calculate the bath liquid. The two routes connect drying, appearance and function evaluation respectively.
If you see the washability statement of the raw materials, can you promise how many times the finished product will be washed?
We prepare pre-wash and post-wash fabric samples according to the fabric, finishing and washing conditions, analyze the maintenance of antibacterial function, and develop supporting wash-resistant finishing.
