What are types of textile testing

Today we will introduce types of textile testing.

Textile shrinkage test

Since we often use washing machines to wash textiles at home, it is essential to ensure the stability of the textile.

Test method: Before washing, we measure the length of the item and determine the change in the size of the sample by measuring the change in markings after washing. According to the type and requirements of the article, we choose the appropriate washing and drying method, add standard detergent and the appropriate amount of water for washing and drying, and finally obtain the test results.

Textile Performance Test

Tensile strength: Tensile strength test is measured using a stretching machine to stretch a specific size of fabric at a constant rate until it breaks with the required force. This test method includes the grab and peel sample methods; according to different test standards and requirements, we can choose the appropriate specific test method.

Pilling resistance: This test involves rolling the fabric under specific conditions, rubbing it for a certain period, and then observing the appearance of pilling and pilling on the fabric’s surface. Pilling refers to the collection of fuzz balls formed by tangled fibers on the fabric surface, and pilling refers to the roughness of the fibers on the fabric surface and the pilling of the fibers, which changes the appearance of the fabric. We can use rated samples or make original comparisons to assess linting and pilling.

Color Fastness Test

Washing color fastness: This test involves sewing samples together with standard lining fabrics. It includes bleaching and washing at the appropriate temperature and alkalinity. The samples are then washed and dried to obtain test results quickly. During the test, we wash friction using a smaller bath ratio and the right amount of stainless steel beads. Finally, we use special gray cards to grade the standard lining fabrics and samples. This helps us obtain color fastness ratings and test results. Different test methods have different temperatures, alkalinity, bleaching, and rubbing conditions. Additionally, they vary in sample volumes. We select the appropriate test method based on the test standard and customer requirements. Generally, colors with poor wash fastness include turquoise blue, bright blue, scarlet red, and navy blue.

Sweat fastness: This test involves sewing samples with standard lining fabrics. The samples are treated with sweat and clamped on a sweat fastness tester. They are then placed in a constant temperature oven for drying. Finally, special gray cards are used to grade the lining fabrics and samples for color fastness ratings and test results. Different testing methods have different sweat ratios, sample sizes, and testing temperatures and times.

Chemical Performance Test

Formaldehyde test: This test extracts free formaldehyde or released formaldehyde from fabric using a specific method. It then conducts a colorimetric test to measure the amount of formaldehyde present.

PH test: We use a pH meter to accurately measure the fabric solution’s pH value accurately, and the value read is the measured pH value.
