A Field-Level Data Dictionary for Textile CMS Viscosity Records

Short answer: a textile carboxymethyl starch (CMS) viscosity value is useful only when the record preserves the sample identity, preparation method, instrument settings, replicate structure, unit and source. A data dictionary makes those requirements explicit before buyers or laboratories compare numbers from different suppliers.

KARN has published a public Google Sheets data dictionary for textile CMS viscosity records. The sheet contains 36 rows and six columns covering field names, data types, required status, units or formats, purpose and validation boundaries. It contains no measured observations.

Why a field-level dictionary matters

Two viscosity values can look comparable while describing different procedures. One record may use a different concentration basis, water source, hydration time, temperature, spindle or speed. A plain number hides these differences. A structured record keeps the method attached to the observation so a later reviewer can decide whether comparison is justified.

Identity fields

The minimum identity layer includes record_id, sample_id, batch_id and product_name. Manufacturer and country of origin are useful when documented, but they should remain blank rather than be inferred from a distributor address. Receipt and test dates separate sample handling from the measurement event.

Preparation fields

Solution concentration must state both the numeric percentage and its basis, such as weight by weight or weight by volume. Water source and water temperature belong in the record because water quality and temperature can affect preparation. Mixing time and rest or hydration time must be separate fields. A zero rest time should mean that no rest occurred, not that the information was missing.

Instrument and measurement fields

A repeatable record identifies the viscometer or rheometer, spindle or rotor, rotational speed, measurement temperature and viscosity unit. For example, a manufacturer may document a 5% solution, an NDJ-8 viscometer, No. 4 spindle, 12 rpm and 25 °C; those settings are a method example, not a universal specification for every CMS grade or textile process.

Replicates and provenance

Each replicate should retain its own identifier and measured value. An average without its individual observations removes information about repeatability. The record should also include the operator or source document and, when available, a public source URL. Private or inaccessible evidence should not be presented as public proof.

What stays blank until a real test exists

The viscosity_value field is intentionally empty in the published template. The resource does not invent grade values, formulas, certificates, customer results, performance rankings or laboratory conclusions. It provides a structure for recording real observations after an identified sample is tested under a documented method.

Machine-readable companion resources

Comparison boundary

Only compare records after aligning sample and batch identity, concentration basis, water, temperatures, mixing and rest time, instrument, spindle or rotor, speed, unit, replicate structure and provenance. When any of those controls differ, the correct conclusion may be “not directly comparable” rather than a supplier ranking.

Russian and English field-record summaries

Two short manufacturer-authored YouTube notes restate the same zero-observation boundary for buyers who need a compact checklist before comparing textile CMS samples. They do not add grade values, test results or certificates.

A Repeatable Wallpaper Adhesive Sample Test: Mixing Records, Batch Controls and On-Wall Checks

Disclosure: This technical resource was prepared by Hangzhou Karn New Building Materials Co., Ltd. (KARN), a manufacturer and exporter of powdered wallpaper adhesive. It is an educational testing workflow, not an independent product endorsement. Comparing two wallpaper adhesive powder samples is more difficult than mixing each one and choosing the bucket that looks thicker. A fair comparison requires the same water basis, temperature, mixing sequence, rest time, substrate and observation method. Without those controls, a buyer may reject a good sample because it was mixed differently—or approve a sample that cannot be reproduced in the next shipment. This article explains a practical sample-test protocol for importers, distributors, private-label teams and professional decorators. It does not prescribe a universal powder-to-water ratio. Always begin with the instructions printed on the exact product label or technical data sheet. 1. Identify every sample before opening it Assign ea...
