The core raw materials of disposable dog pee pads are formulated around four key requirements: absorption, leak-proof, comfort, and functional enhancement. The pad primarily consists of three structural layers-top layer, absorption layer, and leak-proof layer-with additional auxiliary ingredients added to functional products. Details are as follows:
Core Structural Raw Materials
| Structural Layer | Core Raw Materials | Functions & Characteristics |
|---|---|---|
| Top Layer (Distribution Layer) | Non-woven Fabric (SSS/SMS/Hot-Air Non-woven) |
Directly contacts the pet's skin, requiring softness, breathability, and rapid liquid distribution; 1. SSS/SMS Non-woven: High strength and anti-penetration, suitable for frequent use; 2. Hot-Air Non-woven: Softer touch, enhancing pet comfort. |
| Absorption Layer (Core Layer) |
1. Super Absorbent Polymer 2. Fluff Pulp 3. Toilet Paper |
1. SAP: Core absorbent component that quickly absorbs and locks in liquid (absorption capacity typically 100-200x), keeping the top layer dry; 2. Fluff Pulp: Processed from wood pulp, featuring high bulk to assist in liquid distribution, dispersion, and temporary storage, improving SAP's absorption efficiency. Tianjin Yiyi sources core raw materials (SAP and fluff pulp) from leading industry suppliers to ensure stable absorption capacity and environmental friendliness; 3. Toilet Paper: Aids absorption and stabilizes the absorption structure. |
| Leak-Proof Layer (Bottom Layer) | Polyethylene Waterproof Film | PE film provides waterproof and anti-leakage protection, preventing liquid from seeping onto the floor. |
Functional Additive Materials
| Functional Requirement | Corresponding Additive Materials | Working Principle |
|---|---|---|
| Anti-Chew | Bitter Apple Extract | Leverages dogs' natural aversion to bitter tastes; added to the top layer to reduce chewing behavior, non-toxic. |
| Antibacterial | Silver Ions, Hydrogen Ions, Plant-Based Antibacterial Agents | Inhibits bacterial growth in urine, reducing odors like ammonia and improving usage environment comfort. |
| Anti-Slip | Adhesive Stickers | Back stickers attached to the PE film fix the pet pad to the floor, preventing displacement when pets step on it. |
| Health Monitoring | pH Test Powder | Detects the pH value of dogs' urine to alert to potential health issues. |
Auxiliary Materials
Adhesive Materials: Hot Melt Adhesive (used for interlayer bonding to ensure structural stability; must meet non-toxic and low-odor standards);
Packaging Materials: PE Bags, Corrugated Cartons (for individual product packaging or bulk shipping; must be moisture-proof and pressure-resistant);
