Testonic Stain Analysis Kit – Polymeric Structures (PVA / PVAc / CMC / Acrylate) is designed to identify whether stains and local residues on textile fabrics are associated with PVA, PVAc, CMC or acrylate-based polymers.
It is particularly useful in textile processes involving sizing agents, binders, coatings, printing systems and finishing chemicals. From greige-fabric inspection to post-dyeing defect analysis, the kit helps classify polymer-related problems so production teams can focus directly on the relevant chemical and process stage.
Why Is Identification of Polymer-Related Stains Important?
PVA, PVAc, CMC and acrylate polymers can be used in textile sizing, binding, thickening, coating and finishing systems. Local or uneven residues can influence the behaviour of the fabric in subsequent processing.
Polymeric residues may affect wettability, liquor penetration and local dye uptake, later appearing as shade variation, poor dye uptake, hardened areas, uneven surface appearance or recurrent local defects.
Identifying the polymer group directs the investigation toward the relevant sizing, washing, printing, coating or finishing stage and helps the mill plan the corrective process more efficiently.
How Does the Result Guide the Mill?
| Identified Structure | Process Areas to Investigate |
|---|---|
| PVA | Sizing-agent use, size distribution on greige fabric and desizing performance. |
| PVAc | Binder, coating, adhesive or auxiliary applications containing PVAc and possible transfer points onto the fabric. |
| CMC | Sizing and thickening processes together with washing and removal efficiency. |
| Acrylate | Acrylic binder, printing, coating and finishing applications, including dosage and application uniformity. |
Where Is It Most Useful?
Why Does Polymer Differentiation Matter?
Classifying a stain simply as a “polymer residue” may still leave several possible process sources. Because PVA, PVAc, CMC and acrylates are associated with different textile applications, identifying the polymer group significantly narrows the investigation.
Production and quality teams can then focus on desizing performance, binder or thickener selection, printing/coating recipes or finishing applications and plan the corrective process more efficiently.
