Diaper Anti-Side Leakage Performance Tester
Category：Other
Introduction
The Diaper Anti-Side Leakage Performance Tester is designed to accurately measure the liquid loss of nonwoven materials and evaluate the anti-side leakage performance of diapers. It is widely used in the research and development, quality control, and performance testing of baby diapers, adult diapers, sanitary napkins, and other absorbent hygiene products. This instrument provides reliable, quantitative data to guide material design, production optimization, and product performance improvements.
Application
(1) Baby diapers, training pants, and pull-up diapers
(2) Adult incontinence diapers and absorbent briefs
(3) Sanitary napkins, panty liners, and menstrual products
(4) Absorbent underpads, bed pads, and protective sheets
(5) Nonwoven materials, superabsorbent polymers (SAP), and top sheet materials
(6) Liquid barrier and acquisition layers in diaper prototypes
(7) Laboratory testing of raw materials and finished products
(8) Production line quality control and pre-shipment inspection
Standards
The instrument is designed to meet multiple national and international standards, including:
(1) GB/T 28004.1-2021 — Diapers Part 1: Baby Diapers
(2) GB/T 28004.2-2021 — Disposable Diapers Part 2: Adult Diapers
(3) EDANA 152.0-99 — Absorbency Test Method for Nonwoven Materials
