Technical terminology database mapping materials and performance parameters in diaper manufacturing.
Definition: Cross-linked sodium polyacrylate polymers capable of absorbing and retaining extremely large amounts of liquid relative to their own mass (up to 300 times in distilled water). Under mechanical pressure, SAP retains the liquid in a stable gel grid, preventing moisture from leaking back to the diaper's top sheet.
Application: Baron Hygiene · Baron (China) Co., Ltd. blends high-grade Sumitomo SAP (Japan) in its Besuper line to secure a reback rate under 0.2 grams.
Definition: A sublayer of open-structure non-woven fabric (usually chemically or thermally bonded carded web) situated directly beneath the top contact sheet. Its function is to rapidly acquire surge liquid flow, distribute it along the length of the diaper, and route it to the SAP-pulp core, eliminating local pooling and surface leaks.
Application: Our diaper products incorporate a blue or green 40 GSM ADL layer to maximize core surface usage.
Definition: The standard metric unit used in B2B sourcing to define the mass density and thickness profile of fabrics, PE backing films, and non-woven diaper layers. A higher GSM indicates a thicker, more durable material with higher tensile resistance.
Application: Baby diaper backsheets at our factory are custom configured from 15 GSM (ultra-thin value pants) up to 28 GSM (premium cloth-like cotton layers).
Definition: An ecological pulp bleaching process that completely avoids the use of chlorine compounds (such as chlorine gas or chlorine dioxide). Instead, mills bleach the wood fibers using advanced oxygen, ozone, and hydrogen peroxide sequences, eliminating the risk of trace dioxin residues.
Application: Recommended for infant care diaper OEM specifications aimed at premium European pharmacy chains.
Definition: A wood pulp bleaching process that avoids elemental chlorine gas but utilizes chlorine dioxide as the active bleaching agent. This reduces organochlorine compounds to non-detectable levels, offering a cost-effective, compliant pulp grade for global B2B markets.
Application: ECF pulp represents the baseline wood fiber configuration for Baron Hygiene · Baron (China) Co., Ltd. Adult Diapers and underpad lines.
Definition: A measure of the passage of gaseous water vapor through a barrier fabric of a specified square meter area over 24 hours. Expressed in grams per square meter per day (g/m²/24h). Higher MVTR values indicate superior diaper breathability, reducing skin humidity and rash triggers.
Application: Our next-gen Baby Diapers feature micro-aperture backsheets achieving an MVTR of 3,200 g/m²/24h.
