Raw Cashmere Classing and Guard Hair Percentage Estimation
Raw cashmere value hinges on clean down yield and optical verification of residual coarse hair content below zero point five percent by mass.
Scale Height Measurement
Linear Verticality
Digital profilometry quantifies the geometric extension of fibre bundles or yarn cross sections relative to a fixed planar substrate. This scale height measurement operates by capturing the depth profile of a specimen as it passes under a laser or tactile stylus. Analysts apply the resulting data to distinguish between surface topography and bulk deformation in technical textiles.
High fidelity scans provide the necessary input for determining the abrasion resistance of protective outer layers.
Surface Projection
Friction coefficients depend directly on the peak heights detected during this procedure. Precise identification of these elevations informs the development of spinning processes and yarn texturing controls. A low profile reading indicates a smoother surface whereas high values suggest a complex topology.
Topographic Deviation
Discrepancies between theoretical volume and measured height reveal voids trapped within a compressed fabric structure. Quality control systems use these variations to detect inconsistent drafting in carding machines or uneven tension during winding operations. Each scan cycle triggers a comparative audit against predefined geometric tolerances.
Measurement Integrity
Calibration of the sensor head remains the primary prerequisite for accurate performance in a production facility. Periodic verification against reference blocks keeps the error margin within the limits required for precision soft goods manufacturing. Any movement of the specimen during the scanning sequence invalidates the data set for that batch.
Internal consistency in these results verifies the structural stability of the processed materials.
