Flammability testing is extremely important when considering the use of materials in confined spaces that are susceptible to an ignition source. The most common example being that of motor vehicle interiors where matches, cigarettes, etc. can cause a vehicle fire, endangering occupants. Component and device manufacturers will want to subject their product to fire testing to ensure the part becomes self- extinguishing; does not violently burn; does not result in an explosive fire; or that the spreading of the surface burning is prevented. ASTM E1321 - 18 Standard Test Method for Determining Material Ignition and Flame Spread Properties-This type of testing is used to determine the impact of a direct flame on operating or non-operating equipment. Devices tested can range from fuel or hydraulic lines, pumps or actuators for aircraft engines, to telecommunications central office network equipment. Often the test is combined with additional factors, including vibration, pressure, gas and air flow, and temperature variations, depending on formal specification and your individual requirements. Qinsun-lab has many types flammability tester for various materials.such as textile flammability test machines .toy flammability tester .Fabric Surface Flammability Tester and Furniture flammability tester etc.

A textile materia is well known that l with high resistance to abrasion, such as Cordura®, can stand 100 thousand rubs by Martindale without a mass loss or specimen breakdown. Obviously, this kind of material will abrade a woven wool fabric, and not the other way around. Thus, the question arises whether the determination of Cordura® abrasion resistance, or some other the similar high performance fabric, using the Martindale methods, is suitable or the methods should be modified in order to obtain significant results? In addition to the modification of Martindale in the manner described before , some modifications of standard methods of testing abrasion resistance by Martindale are also possible, all of them aiming at obtaining significant results. The Department of Materials, Fibres and Textile Testing, the Faculty of Textile Technology, University of Zagreb, has been involved in testing high quality fabrics intended for military and police use for some time. A number of high performance fabrics have been investigated and the need to determine wet abrasion resistance showed to be one of the key requirements throughout the investigation. Fabrics intended for military and police uniforms are exposed to a number of physical and chemical agents in the course of regular use, rain and moisture being most frequently encountered. This means that, apart from testing dry abrasion resistance, as required by current standard, standard should be complemented by including testing wet abrasion. Such a method for determining abrasion resistance is particularly suitable for damage detection, as damaged textile materials show more pronounced reduction in strength in wet state. The advantage of the modification is that the testing proposed can be done using the same methods, procedures and equipment as with dry materials. Similar to the above, permeability of air and resistance to water with good resistance to abrasion are very important for high performance fabrics used by mountain climbers, soldiers, policemen, firemen, etc. The Martindale method can again be ideally modified to suit the purpose; using the same apparatus, procedure and slightly modified methods it offers proper insight into the influence of wear on water or air permeability. Additional knowledge on the impact of testing abrasion resistance, as related to air permeability and water resistance, will be acquired in this way as well.

Textile testing is the term for a whole series of tests that examine the physical, mechanical and chemical properties of textiles. These tests are sometimes done before a textile goes into widespread use, or they're done on textiles arriving from other countries for sale in US markets. Countries like the United States have established standards for what should and should not be in textile products. Tests can show whether companies making textiles are in compliance or not. Textile testing can ensure that a given textile is what a manufacturer or importer says it is. Sometimes, testing is done while textiles are being manufactured, to identify problems or faults in the machinery making them, and to double-check that materials being used for a specific textile are appropriate.

For laboratory scratch and mar tests, a stylus with a defined geometry is drawn across a specimen surface at a known speed and with a known force. The objective of most scratch or mar resistance studies is to determine the behavior of the material under specific test conditions, establish a relative ranking of similar materials, or to determine the failure limit of a surface coating. This information can then be used to better understand material surface properties and performance characteristics. Similar to wear tests, the amount of scratch damage on a material surface can be influenced by test parameters (e.g. stylus composition and geometry, loading, and scratch velocity) and requires an appropriate procedure to minimize these influences. Inappropriate choice of tip geometry and loading conditions often produces damage that is more severe than in-service damage, resulting in misleading results. As an example, different mechanical deformations may be generated using different scratch indenter geometries: 1mm spherical ball (hardened stainless or tungsten steel); conical diamond; cube corner; pyramidal; cylinder sectioned at 45° to the axis; 0.8mm diameter helix and the radius edge of a paperclip. Variation can also be introduced by the speed the stylus is drawn across the specimen surface. For scratch testers that provide an adjustable speed, care must be taken to ensure the rate of speed is the same for each test. Another consideration is the length of time a stylus sits on a specimen surface before the test commences, and how deep the stylus "sinks" in. Material properties such as surface roughness, hardness, modulus of elasticity, texture, grain, gloss level, and coating thickness will also influence the severity of scratch damage. Although scratching appears to be a relatively simple concept, trying to evaluate and describe the results on a polymeric material is not always easy. Many plastics have visco-elastic properties and the stresses in the plastic may relax during loading. Plus, plastics demonstrate an elastic recovery after applied stresses are removed. For example, parameters such as scratch width, groove depth, displaced material and severity of the damage may change over time. Other issues that may affect the visual perception of scratches include the color of the sample, amount of strain whitening, scratch direction, lighting and viewing conditions, and the amount of time an observer is allowed to view the sample. ------------------------------------------------------------------- For more information about our scratching testing instrument, please contact ·website:http://www.qinsun-lab.com/ · +86-21-6780 0179 · info@qinsun-lab.com · or leave your comments below

Have you ever know about the Standard seam efficiency testing ?A seam is a series of stitches that may be functional or ornamental. Generally a seam is made to join two or more pieces of fabric in garment construction.Actually seam is a line where two pieces of fabric are sewn together in a garment or other article. The aesthetics and performance of the garment are strongly dependent on the seam`s appearance and performance characteristics. The considerations related to seam appearance include colorfastness and the area covered under the seam, as was discussed earlier in the thread testing section. Performance characteristics are more related to strength, elongation, and elasticity.In the face of such a complex information about the Fabric Tensile Strength Tester,many enterprises often feel helpless without knowing a good way to make bright choices. Standard seam efficiency testing can be performed by using a tensile testing machine. First of all, fabric without a seam is placed between the clamps of a tensile testing machine and force is applied until failure occurs. The amount of force required to break the fabric sample is noted. Then, a sewn sample of woven fabric is prepared as explained in ASTM-D1683. The sewn sample size is 4 in. × 8 in. Seam allowance should be 1/2 in. To test seam strength, the fabric specimen containing the seam is placed between the two jaws of a tensile testing machine such that it is directed toward the rear of the machine, using vertical alignment guides. The seam should also be equidistant from the upper and lower clamps of the testing machine. The force is applied until the thread breaks and seam failure occurs. The amount of force required to break the seam is noted. Apart from seam efficiency, seams are inspected for various parameters. Seam slippage, as described in fabric inspection, is a major fault, though one not caused by the seam itself, yet it destroys the aesthetics and functioning. A miss stitch is a major seam fault owing to which the seam fails to grip one or more plies of the fabric in the seaming process.

One test is the ASTM D4157-02 Oscillatory Cylinder (Wyzenbeek) test. [The ASTM D4157-02 is a test of the American Society of Testing and Materials (ASTM). A Wyzenbeek machine is used for this test allowing samples of the test fabric to be pulled tight in a frame and held stationary. Individual test specimens cut from the warp and weft direction are then rubbed back and forth using an ACT approved #10 cotton duck fabric* as the abradant. The number of double rub cycles achieved before two yarn breaks occur or noticeable wear is observed is recorded as the fabric`s abrasion rating. " * The wire screen abradant is recommended by ACT for use with vinyl and polyurethane coated upholstery and may also be used for testing 100% olefin fabrics. Another test is the ASTM D4966-98 Martindale test. [The ASTM D4966-98 is a test method of the American Society of Testing and Materials (ASTM). This is an oscillating test. Fabric samples are mounted flat and rubbed in a figure eight like motion using a piece of worsted wool cloth as the abradant. The number of cycles that the fabric can endure before fabric shows objectionable change in appearance (yarn breaks, pilling, holes) is counted. Number of cycles determines abrasion rating."

Seam Fatigue assesses the ability of a fabric to be sewn effectively for use on upholstery fabric. The cyclic impact of a weighted wheel over a fabric-covered foam block simulates repetitive stress onto a seat cushion. Similar to assessing a portion of your most comfortable reclining chair, a diner booth, or newly upholstered car seat, Dynamic Seam Fatigue testing measures resistance to yarn slippage. The Seam Fatigue Tester is a two station bench top machine, used for evaluating fabric or leather seating materials resistance to tearing or needle hole elongation of a sewn seam. Each station includes a pair of suitable clamps for attaching the test sample. A height gage is used to set the sample clamp separation distance of the 140mm for each station.One or two stations can be tested at a time. The sample is placed on the clamp and the position of the left and right clamping device makes the test sample spacing meet the standard requirements. Set the test cycle numbers and start the test. The Decelerator will drive the middle clamp holder to do the reciprocating movement. The left and right clamp holders are connected with a 3kg load. During the reciprocating motion of the middle clamp holder, the left and right samples will experience a process of loading and unloading of the weight load at the time of around one motion cycle. The proximity switch connected with the counter records the clamping device motion cycle, and the test automatically stopped when reaching the set number of cycles. The fatigue resistance of the joints was measured by the measurement of the change of seam opening in the material seam.

A fatigue test helps determine a material`s ability to withstand cyclic fatigue loading conditions. By design, a material is selected to meet or exceed service loads that are anticipated in fatigue testing applications. Cyclic fatigue tests produce repeated loading and unloading in tension, compression, bending, torsion or combinations of these stresses. Fatigue tests are commonly loaded in tension – tension, compression – compression and tension into compression and reverse. There are several common types of fatigue testing as well as two common forms: load controlled high cycle and strain controlled low cycle fatigue. A high cycle test tends to be associated with loads in the elastic regime and low cycle fatigue tests generally involve plastic deformations. Types of materials for fatigue tests: Nearly all materials may experience fatigue in one way or another during the lifespan of their application. However, in applications where fatigue is a factor it is common to find components made from metals or composites. These materials have a higher fatigue limit than others because of the rigidity and ductility, which are characteristics that tend to increase fatigue strength. Other materials, such as, polymers, ceramics and wood may experience fatigue and also need to be tested to understand how they will respond to these unique stress combinations. The seam fatigue tester is designed to evaluate the fatigue resistance of seam on the material which is applied on the surface of automotive seat. The surface material of car seat (leather, synthetic leather, fabric, etc.) is often stitched together. The stitching strength of the material seam and the fatigue strength of the seam can directly affect the service life of the seat. The strength and life of the joint of the test material can effectively predict the life of the seat and provide the direction of improving the service life. ------------------------------------------------------------------- For more information about our testing instrument, please contact ·website:http://www.qinsun-lab.com/ · +86-21-6780 0179 · info@qinsun-lab.com · or leave your comments below
