How The spray rating tester Works

The spray rating tester comprises a metal framework allowing distilled water to be sprayed through a nozzle onto a test specimen at 45° and 150mm below the nozzle. The appearance of the specimen is compared against an standard photographic scale.A certain volume of distilled water is sprayed into the center of the fixed sample. Before testing is carried out the specimen shall be conditioned for at least 24hours in the standard atmosphere. Water sprayed against the taut surface of a test specimen under controlled conditions produces a wetted pattern whose size depends on the relative repellency of the fabric. -To carry out the test, first of all fasten the test specimens securely in the metal hoop of the water repellency tester so that it represents a smooth wrinkle free surface and place it face up on the tester. -Adjust the metal hoop so that the centre of the spray coincides with the centre of the metal hoop. Later pour 250 ml of distilled water at normal temperature

Definition of Scratch And Mar

For grained surfaces such as pp/talc in automotive applications we use the Erichson multi-finger scratch and mar tester that generates a pattern of crossed lines on test plate. Thereby, the scratching force as well as the diameter of the scratching head can be adjsuted. The difference in color before and after the scratching is measured (D L) and taken as indicator for the scratch resistance. Secondly, we use the five finger scratcher to evaluate the scratch resistance of grained surfaces.  It is a fast method to evaluate the scratch resistance at different forces in one single test.Scratch and mar are types of mechanical surface damage that can occur during normal usage and handling, shipping or assembly procedures.  Defined as "the resistance of a solid body to penetration by an edge or protuberance on a second body that is moving along its surface", scratches are usually associated with a single occurrence in the specimen surface.  Normal scratching includes deformat

Important Points Require Consideration Before Abrasion Tests

A number of important points require consideration before abrasion resistance tests are carried out. The choice of the method may be governed by the type of apparatus available, the precision demanded and so forth. Some of the more important points are condition of the specimen, choice of testing instrument, choice of abrasive motion, direction of abrasion, choice of abradant, backing the specimen, cleanliness of the specimen and instrument, tension on the specimen, pressure between abradant and specimen, end-point of the test etc.  Now there are various abrasion resistance testing instruments available for example, the WIRA abrasion tester, the LIRA abrasion tester, the Taber abraser , the Shiefer machine, the Wyzenbeek abrasion tester , the Stoll universal wear tester, the LINRA wear tester, the BFT abrasion tester etc. The abrasion tester we used here is made by Qinsun Instrument.

Sample Preparation and Test Procedure of Fabric Stiffness Measurement

Sample preparation To ensure consistent fabric properties day after day, all test specimens are first conditioned to approximately 70 degrees Fahrenheit and 65% relative humidity. Once the fabrics are adequately conditioned, test specimens are cut to 8 inches by 4 inches. To ensure the results are representative of the fabric in question, five individual specimens are cut from different locations on a roll of fabric. Next, the specimens are folded in half, resulting in a 4-inch-square folded test specimen. For consistency in testing fabrics that have a different face and back, samples are always folded so the technical face of the fabric is on the outside. Test procedure When a specimen has been prepared, it is placed on the orifice platform and is ready for testing. At this point, the plunger is activated and begins pushing the sample down through the orifice. Once the plunger has forced the fabric through the specimen, the maximum force required to do so is displayed on the

How can you wash and dry clothes with steam?

In a  washing machine , steam and  water  form a dynamic duo. Steam complements water in the cleaning process by keeping the fabrics soft and wrinkle-free. Qinsun-lab  explains the different advantages that steam can offer when applied in three different stages of a washing machine cycle: Pre-wash phase: While the water loads into the wash tub, the steam works with the water to help soak the fabrics more thoroughly. During the washing phase: If added while the detergent is mixed with the water, the steam increases the temperature of the wash tub to improve the cleaning power, which also helps to activate the detergent. It does this by dissolving the detergent more effectively, to get the most out of it as possible. Post-wash phase: Steam added after washing lends more high temperatures to the tub to sterilize the clothes. It also softens the clothes to remove hard wrinkles that formed while the clothes tossed in the tub. The patent goes on to explain that when some fa

Visual Assessment of Fuzzing and/or Pilling by ICI Pilling and Snagging Tester

The viewing cabinet shall be situated in a darkened room. Place the tested specimen and a piece of the original sample, with or without pretreatment ,centrally on the lectern in the viewing cabinet, with the length direction vertical. If necessary use a piece of self-adhesive PVC tape to ensure correct placement. Mount the tested specimen on the left and the original sample on the right. In order to prevent glare from the light source view each specimen from just outside the viewing cabinet, directly in front of the specimen. Due to the subjective nature of the assessment, it is recommended that more than one observer assess the specimens. Grade each specimen in accordance with the grading scheme given in Table1. If the grading appears between two grades, report the“half”grading as,for example,3-4. The test result for each individual observer is the average off our specimen grades. The test result for the laboratory sample is the average of the observer grades. Phot
