Nonwoven fabric tablecloths are tested for quality through several methods, including:
1. Physical Properties Testing:
Tensile Strength: Measures how much force the fabric can withstand before breaking.
Tear Strength: Assesses the fabric’s resistance to tearing.
Bursting Strength: Evaluates how much pressure the fabric can handle before rupturing.
2. Thickness and Weight:
GSM (Grams per Square Meter): Determines the fabric’s weight, which affects durability and opacity.
Thickness Measurement: Ensures the tablecloth meets specified thickness standards.
3. Surface Texture Examination:
Visual inspections for uniformity, smoothness, and any defects in the fabric.
4. Colorfastness Testing:
Wash Fastness: Tests how well the color holds up after washing.
Light Fastness: Assesses resistance to fading from exposure to light.
5. Chemical Testing:
pH Testing: Ensures the fabric is neutral to avoid reactions with food or skin.
Toxicity Testing: Checks for harmful substances or chemicals.
6. Flammability Testing:
Determines how the fabric reacts to fire and whether it meets safety standards.
7. Water Resistance:
Tests the fabric's ability to repel water, which is crucial for tablecloths that might encounter spills.
8. Durability Testing:
Abrasion Resistance: Measures how well the fabric can withstand wear and tear.
9. Environmental Testing:
Evaluates biodegradability or recyclability, important for ecofriendly products.
These tests ensure that nonwoven pp fabric tablecloth meet industry standards for quality, safety, and performance.
