Woven Fabric Stretch Recovery Tester TF154

5.0 (3 reviews)

Woven Fabric Stretch Recovery Tester, to determine the stretch properties of fabrics woven from stretch yarns under a specified tension and extension. Besides, it complies with ASTM D3107. TESTEX is a well-known Woven Fabric Stretch Recovery Tester manufacturer in the industry and currently sells its products to more than 60 countries and regions worldwide.

Description

Application

Woven Fabric Stretch Recovery Tester, is designed to determine the stretch properties of fabrics. The fabrics belong to those that are woven from stretch yarns under a specified tension and extension. This instrument enjoys a wide application in the fabric and textile industry as it can help improve stretch performance. Besides, it owns 6 test positions, ensuring high working efficiency. Moreover, the tester consists of stainless steel, preventing the parts from getting rust. In the testing, clamp the end of one specimen in the top clamp of the stretch. And then make it subject to the specified tension. Finally, we can make an assessment of the stretch performance.

Test Principle

Fabric Growth after Stretching to a Specified Extension—Bench marks of a known distance are made on a fabric specimen. Then, hold the specimen, paired with one used in the fabric stretch test at a specified extension for a prescribed period of time.  Meanwhile, remove the tension from the specimen. Next, measure the distance between the benchmarks after allowing the specimen to relax for various time intervals. In the end, calculate the fabric growth at each time interval from the distance between the bench marks of the specimen prior to stretching and the length after each relaxation period at zero tension.

What is a Woven Fabric Stretch Recovery Tester?

Woven Fabric Stretch Recovery Tester covers the determination of the amount of fabric stretch, fabric growth, and fabric recovery of fabrics woven in whole or in part from stretch yarns after a specified tension and extension.

It is for use with woven fabrics exhibiting high stretch (greater than 12 percent) and good recovery properties from the low tension of fabric width. When making an agreement, this test method is also suitable for fabrics woven in whole or in part from non-stretch yarns that exhibit limits within the stretch characteristics mentioned above.

Stretch Recoverability of Fabric


Fabric stretch recovery is calculated as the percentage of the fabric growth recovered with respect to the fabric growth determined after tension or after a specified extension obtained at various intervals. Fabric with good tensile or elastic properties will shrink itself after spreading and will be difficult to deal with in cutting, sewing, ironing, and other operations. Because of the product drawing, the size changed and the stitching part of the corrugated shape, if the stitching direction of the tension is too large, the sewing is easy to break or shrinks the thread. Therefore, when operating for the above-mentioned fabric, we should choose suitable elastic sutures for tensile properties.



Nominal Definition


Fabric stretch under a specified tension-calculated from the length difference between bench marks prior to application of the tension ad while under the tension.


Fabric growth after a specified tension-calculated from the length difference between the bench marks prior to application of the tension and after relaxation.


Fabric growth after stretching to a specified extension-a specimen is held at a specified extension for a pre-scribed period of time. Calculated from the distance between the bench marks of the specimen prior to stretching and the length after each relaxation period at zero tension.


Fabric recovery-calculated as the percentage of the fabric growth recovered with respect to the fabric growth determined after tension or after a specified extension.



Test Procedure


1 Cut a certain number of samples of 65mm*560mm size as required. Ensure the specimens are free of folds, creases, or wrinkles. Avoid getting oil, water, grease, etc. on the specimens when handling.


2 Clamp the end of one specimen in the top clamp of the stretch tester such that the folded and sewn loop end hangs freely.


3 Measure and record the distance between the bench marks to the nearest 1 % or 1 mm (0.05 in.) and record as Distance O1 (original before tension is applied).


4 Insert a dowel pin, or equivalent, through the loop and place the tension weight hook through the slit in the fold and over the dowel pin, thereby providing the specified tension to the specimen.


5 Pre-stress the specimen slowly by cycling 3 times between 0 and the total tension specified. A complete cycle should take approximately 5 s of which the specimen is under the specified tension for approximately 3s. Following the third cycle, apply the specified tension for the fourth time and measure the fabric stretch.
