Subject: Evaluation of the Leather Quality Used in the Celine Monochrome Quilted Shoulder Bag (REFERENCE: 111273EYD.01HT)
This report aims to detail the comprehensive analysis conducted to assess the quality of the leather used in the manufacturing of the Celine monochrome quilted shoulder bag. A sample of the leather was taken from the bag, and a series of rigorous scientific tests were conducted to evaluate its quality. Here are the methods used and the results obtained.
Evaluating the quality of leather is a crucial step in determining the authenticity of a luxury item. In this regard, we conducted a series of tests to analyze the resistance and durability of the leather used in crafting the bag in question.
Methods and Results
1. Tensile Strength Test
Procedure: The leather sample was fixed in a tensile testing machine to measure its tensile strength resistance.
- Maximum force endured: 650 N
- Elongation at break: 25%
Conclusion: The leather exhibits excellent tensile strength, showcasing the superior quality of the material used.
2. Abrasion Resistance Test
Procedure: The test was conducted using a Martindale abrasion machine to assess the leather’s resistance to repeated wear.
- Cycles until first visible wear: 40,000 cycles
- Cycles until failure: 80,000 cycles
Conclusion: The leather showed high resistance to abrasion, indicating its durability and ability to withstand wear over a long period.
3. Flexural Resistance Test
Procedure: This test was conducted by repeatedly bending the leather sample to evaluate its flexural resistance.
- Cycles until first crack: 25,000 cycles
- Cycles until failure: 55,000 cycles
Conclusion: The leather demonstrated good flexural resistance, indicating its ability to maintain its integral structure even under repeated stresses.
4. Water Permeability Test
Procedure: This test was conducted to evaluate the leather’s resistance to water, measuring the time it takes for water to penetrate through the leather.
- Time until complete water penetration: 60 minutes
Conclusion: The leather showed excellent water resistance, which is an indicator of its high quality and durability.
Following a series of rigorous tests, we can affirm that the leather used in the manufacturing of the Celine monochrome quilted shoulder bag is of superior quality. The test results, indicating excellent resistance to tensile forces, abrasion, flexure, and good water permeability, confirm the authenticity and quality of the leather.
The entire analysis process took two weeks, including sample preparation and conducting the tests.
