Nonwoven roll sample approval and converting line

Kimberly-Clark Sampling and Specification Services

A staged path from functional brief to converted-product evidence.

Specification normalization

Translate “soft,” “breathable,” “absorbent” or “protective” into polymer, web formation, layer sequence, basis weight, width, treatment, roll and named functional methods.

Sample selection

Choose a hand sample for touch and appearance, roll sample for converting behavior, treated specimen for functional screening, or production material for lot release.

Evidence alignment

Connect barrier, absorption, filtration, tensile, elongation or linting language to a method, conditioning, specimen orientation, repetitions and pass level.

Five approval steps

  1. 1

    Define function and interface

    Identify the finished product layer, adjacent materials, bond route, fluid or particle challenge, user contact and converting conditions.

  2. 2

    Screen construction

    Compare spunbond, meltblown, SMS, SMMS or other specified webs by basis weight, pore structure, strength, softness and uniformity.

  3. 3

    Run conversion trial

    Check unwind, tension, slitting, folding, heat or adhesive bonding, sealing, dust or lint and line speed within the planned equipment window.

  4. 4

    Validate applicable methods

    Test the relevant specimen and aged state. Material evidence does not automatically establish performance of seams, bonds or a regulated finished product.

  5. 5

    Release the lot

    Reconcile construction, treatment, roll identity, inspection, required reports, accepted deviations and change triggers before production use.

Scope note

Changes in polymer, fiber diameter, web formation, basis weight, surfactant, charge, finish, color or converting route can alter performance. Earlier evidence is reviewed before being applied to a changed construction.

Commercial feasibility includes web campaigns, treatment batches, usable width, roll build, splice limits, sample quantity, MOQ, test timing and destination. A medical, hygiene or protective end use remains separate from finished-product classification and regulatory evidence.

The release record names the reviewer, sampling frequency, accepted deviation and change trigger. Production rolls are checked against the approved construction rather than an application label.

Submit a converting case

Include the layer role, adjacent materials, line process, method, quantity and target date.
