Why this session matters
Behind every high-performing baby diaper or sanitary napkin is a disciplined approach to materials selection and qualification. In this live session, Welldone Machine will unpack the raw materials that drive absorbency, fit, and line efficiency—and show how to translate lab metrics into real converting performance and yield.
What you’ll learn
1) SAP (Super Absorbent Polymer)
How to balance CRC (Centrifuge Retention Capacity) and AUL (Absorbency Under Load) for your product tier.
Powder distribution, dusting control, and target add-on for T-shape, I-shape, and Closed (pull-up/H-style) structures.
Storage & handling to prevent caking and humidity drift.
2) Spandex (Elastic yarn)
Denier, elongation, and force-relaxation—what your operators actually feel on the line.
Heat setting vs. adhesive windows; over-stretch protection to prevent leg-cuff lift.
3) Nonwovens (Spunbond/Spunlace/SMMS)
Matching GSM, MD/CD tensile, softness and air permeability to topsheet, ADL, and backsheet roles.
Film-laminate breathability vs. leakage risk, and how to read supplier COAs.
4) Elastic Nonwoven
Strain–recovery behavior, creep control, and bonding choices (ultrasonic vs. adhesive).
Cost–performance levers for ear/waist applications.
5) Anion Chips (optional feature)
Integration without compromising line speed: recommended sizes, placements, and compliance notes.
6) Hook Tapes & Fastening Systems
Peel and shear strength targets by size (NB–XL).
Hook/loop compatibility matrix, adhesive selection, and splice quality for high-speed runs.
Application mapping: from spec sheet to stable production
We’ll connect the dots between material specs and line settings—nip pressure, web tension, cure time, and defect-ejection thresholds—so you can move from sample approval to stable mass production faster. Expect practical guidance you can take straight to your 1,000 m²+ plant with 4–6 operators per line.
Quality & compliance you can trust
Supplier due diligence: ISO-certified partners, QVL (Qualified Vendor List) setup, and lot traceability.
Incoming QA: sampling plans (AQL), key test methods, and COA/MSDS review.
Storage SOPs for humidity-sensitive inputs and best practices for FIFO/FEFO.
What’s on the live agenda
A concise primer on each material class with real production examples.
Online walk-through of a nonwoven production line and converting interfaces.
Live Q&A—bring your BOM, monthly volumes, and target product positioning.
Who should attend
New factories and first-time entrants to hygiene converting
Procurement, QA and process engineers building or refining specifications
Investors planning capacity expansion or platform upgrades
