MICOOSON supplies microfiber synthetic leather materials for customers evaluating different product specifications and performance requirements.
For footwear material buyers, water penetration, water absorption and water vapour permeability are important characteristics when selecting upper materials.
MICOOSON has third-party test documentation for a submitted black microfiber material evaluated under ISO 20344:2011.
The report records Pass conclusions for the specified water penetration, water absorption and water vapour permeability requirements.
ISO 20344 establishes test methods for evaluating specified properties of footwear and footwear components.
The submitted microfiber sample was tested using ISO 20344:2011 methods covering:
Water Penetration and Water Absorption (Upper)
Water Vapour Permeability
Water Vapour Coefficient
These tests provide material performance information under defined laboratory conditions.
A material test report does not automatically establish that a finished safety shoe has achieved S2 classification or certification.
The laboratory test report identifies the following information:
Report Number: SL92309277187301FW
Report Date: May 5, 2023
Sample Description: MICROFIBER
Sample Color: Black
Test Method: ISO 20344:2011
Water Penetration and Absorption Method: Section 6.13
Water Vapour Test Methods: Sections 6.6, 6.7 and 6.8
Overall Conclusions: PASS for both reported test categories
The testing information applies to the submitted sample and specified laboratory conditions.
Water penetration testing assesses the amount of water passing through a material under the specified test method.
Water absorption testing evaluates the water absorbed by the tested material.
The report records the following results:
Water Absorption: 6.8%
Reported Requirement: Maximum 30.0%
Water Penetration: 0.02 g
Reported Requirement: Maximum 0.2 g
Test Conclusion: PASS
These values indicate that the submitted microfiber sample met the stated water penetration and absorption requirements.
The results do not mean that every microfiber leather grade or finished footwear product is completely waterproof.
Water vapour permeability is an important property when evaluating moisture transfer through footwear upper materials.
The report records:
Water Vapour Permeability (WVP): 2.03 mg/(cm²·h)
Minimum WVP Requirement: 0.8 mg/(cm²·h)
Water Vapour Coefficient (WVC): 18 mg/cm²
Minimum WVC Requirement: 15 mg/cm²
Test Conclusion: PASS
The documented water vapour tests were performed at (23 ± 2)°C and (50 ± 5)% relative humidity.
The report also specifies 20,000 Bally flexing cycles as pretreatment, a one-hour pre-run period and an eight-hour test period.
These findings apply to the tested microfiber sample and should not be interpreted as complete breathability performance of a finished shoe.
Footwear upper materials may need to balance resistance to water penetration with the ability to transfer water vapour.
When evaluating microfiber synthetic leather for footwear applications, material buyers should consider:
Water penetration test results
Water absorption performance
Water vapour permeability
Water vapour coefficient
Material thickness and construction
Surface treatment and backing structure
Intended footwear application
Required test methods
Customer-specific performance requirements
Finished footwear performance also depends on the overall shoe design, construction, seams and other components.
No.
ISO 20344 specifies test methods used to evaluate footwear and footwear components.
S2 is a classification associated with applicable safety footwear requirements, and determining the classification of a finished shoe involves additional criteria.
The SGS test report for the submitted MICOOSON microfiber sample documents the specific upper material tests performed. It does not certify a finished shoe as S2.
MICOOSON supplies microfiber synthetic leather materials for customers with different surface, backing and performance requirements.
Customers evaluating materials for footwear applications can contact MICOOSON to discuss product specifications, available samples and relevant technical documentation.
Buyers should confirm whether the available report corresponds to the specific material grade and production batch they intend to purchase.
Yes. MICOOSON has a third-party test report for a submitted black microfiber sample evaluated under ISO 20344:2011.
The reported water penetration value was 0.02 g against a stated maximum requirement of 0.2 g.
The report recorded water absorption of 6.8%, compared with the stated maximum requirement of 30.0%.
The report recorded a WVP value of 2.03 mg/(cm²·h), above the stated minimum requirement of 0.8 mg/(cm²·h).
The reported WVC value was 18 mg/cm², compared with the stated minimum requirement of 15 mg/cm².
No. The report records material test results under specified laboratory conditions and does not establish complete waterproof performance for all applications.
No. The report addresses specified material tests. It does not constitute S2 certification of a finished safety shoe.
No. The results apply to the specific submitted sample and test conditions documented in the report.
Customers can contact MICOOSON to enquire about material specifications, product samples and available technical testing documentation.
