What are the textile instruments for yarns, fabrics and garments?
There are many types of textile testing instruments and these are used in the textile industry in different ways and with different processes. Here are some test instruments for yarn and fabric/garment testing procedures. Yarn Tester: Crimper Tester: Crimping is an important property that determines carding behavior, drafting and failure rates in yarns. Crimping frequency, amplitude stabilization, crimping, crimp elongation, and decrimping points are all important in determining crimping properties. A crimp tester is used to determine the potential for swell-textured yarns. Use: The crimp tester can be used for polyamide and polyester textured yarns. The frequency and amplitude of the crimp can be determined by projecting a magnified image of the fiber on the screen. • The Curl Stiffness Tester instrument is based on the characteristics of the test method. • The tester can be used for polyamide and polyester textured yarns. Instrument mounted on a sturdy metal base. Small and lightweight. ? Heating device thermal crimp shrinkage measurement. How does the curl tester work? The principle of this test is as follows: The load is equivalent to 0.09 g/spin on the end of the yarn dipped in water. A fixed time load was further reduced to 0.0018 g/count and after the reduction in yarn length for a fixed time. The reduction in yarn length of a crimped elastic yarn expressed as a percentage of the original length. The commonly used test methods are as follows: 1. Place the yarn that is on the base plate of the yarn guide Hank under the device for the bolt test kit. 2. The threaded yarn gate is adjusted by tensioner and tension, pulling the yarn through the gate; a gradual elimination of the crimp can be observed. 3. The inner side of the capstan at the front end of the yarn. Wind One Hank with multi-strand options, 0.09 g/count, 0.0018 g/count loads can be provided by setting connection weights applied to each yarn. (Load and ply number are most commonly found in the second manual. Listed in the given table) Clamp the outside of the final chain capstan. 4. Add the appropriate light chain extending through the fork to the lower end of the Hank winder arm. Appropriate weights are added for the light-weight lower hooks. 5.5. Remove the Hank and the hoisting weight to unscrew the Hank rod from the winder arm. 6. Attach additional card-supported Hank bars to immerse the Hank in the water and clamp the RIM in the graduated cylinder with the two support cylinders. 7. Start stop table. 8. Put Hank in the first 2 minutes and measure Hank's length at 10.9. The 2 minute soaking time to raise the grid removes the weight so that the weight is released from the S-hook. 10. After a 2-minute measurement length is LS Hank. Crimper = 10 - Ls/L0 x 100 Yarn Appearance Panel Reel: Yarn Appearance Panel Winder is used to compare the presence of non-compliance with standard photos for visual inspection of uneven appearance along the yarn length. Established yarns of different thicknesses were evaluated; the spacing between the bales was appropriately chosen to clearly give a pattern recognition. Yarn Appearance Board Hoist is used for visual inspection of wrapping line isometric parallel wrapping on board. Yarn appearance trigger features: ? Manual operation.·Check yarn evenness and appearance. For accurate assessment of imperfect grades, accurate assessments are made against comparative criteria. • Used for yarn winding on a blackboard for visual inspection and grading yarn according to ASTM standards. Wide range of rectangular and wedge plate options. How Does Yarn Appearance Roll Works? Packing Board:- The number of yarns to be tested must be determined. The proper spacing of the yarn packages on the board must be found from the table. • Parallel/tapered plates must be fastened to stubs. The spacing of the yarns on the cardboard must be checked by making a small sample package. The moving block must be raised. It was brought to the right and released. The yarn guide fixed to this block must be aligned with the point of the winding where it is located. To ensure this, a red marker is present to guide the road. • The package containing the yarn to be tested must be placed on the stand. The yarn must pass through the tensioner and the eyes on the front bracket and moving block. The tension on the yarn must be adjusted so that it moves freely on the rotating plate. Wrap the yarn around the board until a wide enough band is formed. Cut the yarn and remove the board from the device. Evaluation: Evaluate the evenness grade of the yarn by comparing the master photos of the same pitch. The standard has 4 main photos: A, B, C, and a pitch in each. • Compare the appearance of specimens with different ASTM cotton yarn standards. A given grade is equal to or better than that of the next higher grade. Fabric Inspection Instruments: GSM Knife: GSM Knife is used to accurately determine GSM (grams per square meter) of any type of fabric. This knife is a circular cutter for GSM fabric samples except for uniform circular fabric cutting. Specimen cutter with the help of fabric GSM is an area of 100 cm².
