Tinius Olsen - Testing Textiles
 Today’s technology in ropes, cables, fishing nets, lifting and support straps is increasingly advanced, straps made from super strong polyethylene fibre deliver a tensile strength which can be up to 15 times stronger than an equivalent steel on a weight for weight basis. Such polyethylene based technologies float on water, are resistant to moisture, UV light, chemicals and are altogether strong and durable. Additionally the yarn technology has applications in sporting products, the medical industry and bullet resistant body armour and clothing.  Like all materials the strength and performance of the yarns and or finished products such as ropes, straps etc must be tested and quantified. The solution is a Tinius Olsen materials testing system based on a Tinius Olsen Horizon materials test and analysis platform working with a capable test specimen gripping system to ensure zero slippage of the specimen during the test while ensuring no premature break due to excessive clamping force, and a video extensometer capable of accurate measurement of strain (capable of being classified ASTM E83 B1 and ISO 9531 0.5) through specimen failure, however violent the break.
3 mouse clicks and the tensile test is done, results automatically analysed for Pass\Failure against user defined limits, stored for use by a LIMs system and available in a user specific format, be it printed, PDF or other.  Real time video of the test specimen performance is live during the test and immediately available post test for reanalysis not just for visual inspection but for new calculations in terms of new gauge lengths and strain analysis.
Complete proven tensile systems are available from Tinius Olsen, additionally specimen grips and video extensometry are available from Tinius Olsen compatible with most global branded testing machines from USA, Germany, Japan and China. |

 In the lead-up to the holiday season in Luxemburg, toy safety was the subject of a lot of media attention. Luxembourg does a lot of importing from the Far East then re-exports these goods throughout Europe, so it is vital that the items are safe. ILNAS is the Luxembourg governmental department for standardisation, somewhat similar to ASTM or BSI, and are responsible for making sure all products coming in the country meet Luxembourg (European) regulations. ILNAS have a laboratory that does Market Surveillance and testing and they recently bought one of our machines to check that toys conform to EN 71 Part 1 for tensile and compression strength; this is part of a whole range of tests that are required to be performed on these toys. This laboratory and their work was featured in newspapers and on tv. Click here to preview the tv news report.

 A new test method for measuring the moisture handling properties of performance fabrics for active wear and other apparel has earned approval from the American Association of Textile Chemists and Colorists (AATCC) after a lengthy review. The SDL Atlas Moisture Management Tester (MMT) plays a key role in the new protocol. Recent studies have revealed that for most active wear purchasers, the comfort of their apparel’s fabric is closely linked to its ability to handle moisture such as perspiration. Researchers have been seeking to develop a means for objectively measuring and documenting comfort levels and moisture handling. The newly adopted AATCC TM 195 test method and MMT from SDL Atlas promise a step forward. The AATCC approval process is important for new technology. On any proposed test method, every objection and negative are carefully considered by committee members. Complete agreement is required before a method can advance to publication. Copies of AATCC TM 195 may be ordered from www.aatcc.org. More than 40 of the desk-top MMT units are currently used by laboratories in Asia, Europe and the Americas, said Robert Lattie, Director, Product Management at SDL Atlas. The unit dynamically measures liquid transfer behaviour in knitted, woven and non-woven textile fabrics using upper and lower concentric moisture sensors. It generates six key indexes and a quantifiable one-way moisture movement index value. This new dynamic unit can demonstrate the ability of a fabric to improve apparel comfort. The MMT is recognized and used for both R&D and quality control by a growing number of sportswear and performance fabric manufacturers serving this critically important segment. |

 Sylvia Hillier our Textile Testing Expert attended the ISO TC 38 meetings in September located in Beijing, China. The ISO meetings are held every two years and bring together members of the working groups, sub-committees, ending in the plenary meeting of ISO TC38.
The meetings were very successful and of significant importance this year for the UK as for many years of holding the Chair & Secretariat of ISO TC38, it has now been handed over to China & Japan Standards Organization Bodies as a joint venture.
The meetings was attended by key members of the committees from across the globe, and included Bob Lattie of SDL Atlas, who represented the American National Standards Institute (ANSI), and Sylvia Hillier of Tinius Olsen, who was part of the UK delegation from the British Standards Institute. Both Tinius Olsen and SDL Atlas have taken an active role in International Standardisation for many years along with many other companies within the global Textile Industry.

 SDL Atlas is targeting its innovative, new tabletop PnuBurst unit to customers who want the convenience of a preprogrammed unit for basic burst testing but don’t need the extended range of the company’s popular AutoBurst model. Both the PnuBurst and AutoBurst, the company’s premier burst tester, are built and certified to global safety and testing standards. Both deliver consistent and accurate testing for woven and non-woven textiles, paper, paperboard and films. Introduced as a cost-saving option, the PnuBurst design features a pneumatically operated diaphragm, a color touch-screen controller preprogrammed for major test protocols and automatic bell size and clamp ring detection. The PnuBurst offers convenient out-of-the-box operation, enabling laboratories to conduct burst tests up to 1500kPa (15bar, 217psi.) Its USB port, data cable and onboard software allow users to save and analyze test data as they see fit – or streamline their tasks by simply viewing and recording results brightly displayedon the PnuBurst’s colorful instrument control screen. For users requiring an extended test range, the SDL Atlas AutoBurst offers labs a fully automatic but traditional hydraulic technique with up to 6000kPa (60bar, 870psi) operation – performance superior to that of competitive models. The AutoBurst is ideal for testing paper, apparel fabrics, technical textiles and other materials where reliable burst strength measurements are critical. In addition to a full selection of test bells, the SDL Atlas units measure distensions up to 70mm – key for accurate testing of elastic fabrics. |
