As a global benchmark manufacturer of large-scale disposable hygiene care products, Tianjin Yiyi has been engaged in the R&D and production of dog pee pads, dog diapers, cat pee pads, baby underpad mats, adult care pads and other categories for decades. We have established 5 standardized professional laboratories fully equipped with a complete set of precision physical and chemical testing instruments, and built a closed-loop full-chain quality inspection system covering raw material incoming inspection, in-process production monitoring and finished product ex-factory testing.
On the one hand, our laboratories strictly control the quality of every batch of goods delivered by ourselves to avoid quality fluctuations. On the other hand, we open services including sample analysis, competitor benchmarking, formula adjustment and customized solution development to all clients. Accurate test data serves as a solid foundation for your market layout and product iteration upgrades.
What Performance Tests Can Tianjin Yiyi's Laboratory Conduct For Disposable Pee Pads?
We conduct a full range of standardized simulated tests targeting the core functional performance of all types of disposable pee pads to quantify each key technical index precisely:
1. Absorbency Capacity Test
By simulating urine fluid conditions, we calculate the total liquid absorption volume of the entire pad. We distinguish absorption gaps among lightweight daily-use versions, thickened overnight versions and extra-large-size pads, and accurately calculate total absorption changes brought by different SAP (Super Absorbent Polymer) ratios, ensuring the liquid-bearing capacity of our products meets diverse consumer demands.
2. Absorption Speed Test
We inject quantitative standard test solution and record the total time required for complete liquid penetration into the pad core. This test intuitively compares the water permeability of the top non-woven fabric and the influence of core structure on penetration efficiency, resolving pain points such as liquid outflow and surface water accumulation. It provides reliable data support for quality control of fast-absorbing disposable pee pads.
3. Dryness (Rewet) Test
Constant pressure is applied to simulate the dead weight of pets and human bodies after liquid absorption. We measure the weight of liquid re-permeating back to the pad surface. The lower the rewet value, the longer the pad surface stays dry. This effectively prevents red paw pads in pets, diaper rash in infants and bedsores for bedridden elderly people, making rewet volume the core criterion for evaluating product comfort level.
4. Overall Leakage Prevention Test
Leakage tests are carried out under static placement and pressurized conditions to verify the liquid barrier performance of the bottom PE waterproof film and the sealing tightness of edge sealing workmanship. It stops urine side leakage and bottom leakage that would contaminate floors and carpets, comprehensively validating the overall leak-proof performance of the whole pad.
5. Mechanical Tensile Strength Test for Materials
Bidirectional tensile tests (dry & wet state) are performed separately on the hydrophilic top non-woven fabric and bottom waterproof PE film to measure material breaking strength and elongation performance:
- The top non-woven fabric features excellent toughness, resisting tearing and lint shedding when pets step on or scratch the pad;
- The bottom film is stretch-resistant and not easy to rupture, avoiding liquid leakage during usage.
What Value Can the Pee Pad Testing Services of Tianjin Yiyi's Laboratories Bring to Clients?
1. Full-process In-house Quality Inspection for Stable Delivery of Qualified Batches
Tianjin Yiyi's laboratories are deeply embedded in every production link: from random sampling inspection of upstream raw materials (non-woven fabric, SAP, fluff pulp, PE backsheet) upon warehousing, to process patrol inspection on production lines, and final random sampling check before finished product packaging. Samples of every batch are archived for traceability.
Once index deviations are detected during testing, we adjust raw material formulas and production processes immediately at the source to eliminate common quality defects including insufficient absorption, leakage, fragile top layer and excessive rewet. Consistent product quality has earned long-term repeat orders from supermarkets and brand owners across the globe for decades.
2. Custom Sample Testing & Analysis to Drive Product Iteration with Precise Data
Cooperating clients may send their own on-sale products or benchmark competitor samples to our laboratory for professional competitor analysis services:
- Disassemble pad structures, calculate product basis weight, SAP addition dosage and fluff pulp material;
- Compare all performance data item by item (absorption speed, total absorbency, rewet, leak resistance, tensile strength, etc.) and issue a detailed benchmark test report;
- Customize optimized formula structures based on your target sales market, price range and end-user demands. We can adjust production processes relying on test data to develop differentiated products, including antibacterial pee pads, pH health indicator pads, eco-friendly PCR material pads, and bitter apple infused anti-chew pet pee pads.
From cost-effective entry-level mass-market pads to premium functional upgraded products, Tianjin Yiyi's laboratories help you accurately define product positioning via objective test data, cut trial-and-error costs, and rapidly launch pee pads and diapers tailored to local market demands.
