技术概览
荣沣纺织生产水溶性 PVA 纱线，在织造、针织等加工过程中保持稳定强度，并可在设定的水洗条件下受控去除。
Water-soluble PVA yarn works as a temporary process material. It must remain stable through winding, weaving, knitting or embroidery, then lose strength and leave the construction during a controlled water treatment. A useful specification therefore combines yarn construction with a defined dissolution method instead of relying on a temperature label alone.
Three Thai currently develops PVA yarn around 20°C, 40°C, 55°C, 60°C, 70°C, 80°C and 90°C process targets. The suitable grade depends on exposure time, bath movement, fabric density, chemicals and the acceptable removal endpoint. We confirm the exact count and current production range after reviewing the buyer's process.

工艺指南
从需求到批量供应的三步流程
Define the temporary function
Explain where the yarn provides support, the tension it experiences and the point in production when it must be removed. This prevents a grade that dissolves correctly in a beaker but fails during textile processing.
Set a repeatable removal method
Record water temperature tolerance, exposure time, liquor ratio, agitation and whether the endpoint is softening, loss of strength or complete visible removal.
Approve a production-representative sample
Test the densest or most difficult part of the fabric with the intended dyes, auxiliaries and finishing sequence. Link the approved result to a written product specification.

产品常见问题
Can yarn be selected by dissolution temperature alone?
No. Temperature is a useful starting point, but yarn count, twist, fabric construction, water movement, time and finishing chemistry can change the observed removal result.
What should be included in a sample request?
Send the count system, single or plied construction, target temperature and time, textile process, expected order volume and delivery destination.
How should two PVA yarn samples be compared?
Use identical specimen size, bath volume, temperature tolerance, agitation and endpoint definitions, then record processing stability as well as removal performance.
