Calculating Commercial Mass Regain Adjustments for Dehaired Specialty Animal Fibres
Commercial mass regain adjustments recalculate dehaired specialty fibre billing weight by converting net scale mass to clean dry keratin plus official allowances.
Bale Coring Specs
Sampling Standard
Core sampling protocols extract representative fibre tubes from compressed packaging without destroying the bulk consignment. Adherence to bale coring specs ensures that subsequent laboratory yield and fineness measurements accurately represent the entire lot. Standardised patterns dictate the number and placement of pressure probes driven into dense packaging units.
The boundary of these requirements covers physical specimen extraction, stopping before laboratory washing or optical analysis begins.
Core Geometry
Tube dimensions determine the volume and fibre length distribution of retrieved samples. Probes with tip diameters between eleven and fourteen millimetres capture balanced cross-sections of raw grease wool or fine hair. Cutting edge sharpness prevents fibre push-aside during insertion, securing an unbiased ratio of long to short fragments.
Penetration Mechanics
Mechanical pressure drives hollow tip tubes horizontally or vertically into dense bales to reach inner layers. Varying pack densities demand calibrated thrust forces to prevent core tube deformation or sample scorching from friction heat. Technicians collect specimens across multiple bale faces to counteract density gradients caused by hydraulic pressing.
Representative sampling depends on complete tip penetration across the entire bale depth, eliminating surface bias caused by external contamination or localized moisture loss during transit. Samples collected from shallow penetrations fail verification audits.
Lot Verification
Combined core masses must meet minimum weight criteria set by commercial testing houses. Laboratory technicians weigh gathered cores immediately to record lot moisture before ambient humidity shifts weight.
