Before manufacturing any product the first thing in a manufacturer’s mind is its usability and quality of the product – in short customer satisfaction.
Production of spandex is no easy task and to ensure that the quality is maintained is not every body’s cup of tea. So, every person involved in the production of spandex yarn has to be well aware about how the entire process of spandex yarn manufacturing works and how to control it to achieve the required high quality yarn.
Spandex yarn quality is mainly checked by checking the below properties and comparing them to the required standards:
Tensile properties Recovery properties Draft ability properties
1. Tensile Properties: Testing of tensile properties need specific equipment with special kind of jaws and specific test method as the elongation % of spandex is very different to any other yarn used in textile application.
Tensile properties cover the following test parameters.
Elongation: It is defined as the “amount of stretch that a fiber can exhibit/withstand” when allowed to stretch under load till break. A good spandex exhibits elongation % between 450-550%.
Tenacity: Tenacity is the test property which measures the relative strength of the yarn. Ratio of breaking force to yarn linear density is denoted as tenacity.
Modulus at 300% elongation: Load required to elongate the yarn up to 300% elongation.
2. Recovery Properties: A good spandex should recover close to its original length once after stretching and releasing the applied load. Specific test method is used to test the elongation recovery after stretching the yarn up to 300% elongation. Minimum of 90% recovery in this test qualifies a spandex for textile application.
3. Draft ability properties: Draft ability properties are tested under dynamic condition. Specific equipment is designed to vary unwinding and winding speed of spandex with different friction points to test the draft ability.
Compression wear garments are: piece of garment / clothing which fits tightly and exerts pressure around the area worn on, mainly for medical, body shaping and sports purposes. They are generally used to provide health benefits, such as shaping the body, supporting healing after medical procedures and to provide support for people who have to stand for longer periods of time, it also aids in increasing the circulation of blood.
Now-days compression garments have evolved and are used in combination with various athletic sports-wears, in order to provide compression on the muscles to increase the blood flow, which in turn improves performance and reduces the risk of muscle or tissue injuries like chafing and rashes etc. widely faced by sportsmen and at the end also accelerates muscle recovery during and after the activity/exercise.
There are various types of compression wear having required pressure range of mainly between 5-30 mmHg. Most commonly compression garments are made from Spandex fibre. Spandex fibre due to its high stretch, recovery and tensile properties proves to be a suitable match for construction of compression garments and are directly related to compression effectiveness. Apart from spandex fibre/ elastomeric fibre in the core construction, the engineering of the compression garments is mainly formed by stretchable structures to achieve the optimum/required stretch and compression.
Other fibres used along with spandex are: nylon, cotton, and polyester. The various types of compression garments apart from core spun ones are, knitted fabric compression garments and spandex platted cotton fabric compression garments.
With a belief that a new start to the year deserves a new dress, party owls are all set to begin their hunt for the perfect dress to welcome the New Year in style. If you too are oblivious of the dress styles that are hogging the limelight this season and would be the perfect fit on your body, you might wanna scroll through our top picks of the season for a little inspiration.
A delicate lace dress accented with chic detailing not only makes you look festive, but actually makes you feel so. The spandex fiber-infused built of the dress makes it fit like a glove without breaking off the delicate threads that make up its exquisite details. Adding femininity and sophistication without going over-the-top is not that difficult, after all!
Nothing seems more flattering than a dress that traces the gentle curves on the body while making a statement, and a stretch Bodycon dress gives you just that! If a little tummy is what’s keeping you from trying out this diva among dresses, go for dark colours as they direct the focus away from the belly.
If you are in search of the easiest way to look effortlessly glamorous, then look no beyond! That’s because hosiery qualifies among the most comfy fabrics, thanks to its stretch quality. It even helps you sport a form-fitting fit. The dresses made with hosiery yarn have a way of standing out among the crowd without making it look like you’re trying too hard.
Trends sure change year after year, but one thing that shouldn’t, is your unique style. Just make sure that the dress you choose is endowed with the gift of stretchy spandex fiber if you won’t mind some extra comfort while looking like a dream!
What stretches up to over 500 percent its size and still manages to retain its shape on recovery?
Oh! That’s another thing you probably didn’t know. Elastane, elastane fibre and Spandex fibre are used interchangeably across the globe. Spandex, however, is used more commonly than the rest, more so in the United States of America, so it was natural for the term catch on to the rest of the world.
Remember Spanx, a stretchy multi-apparel line introduced as slimming wear to the market? It capitalised the most on elastane and its stretch capabilities. They took elastane wrapped with hard yarn (this blend is also known as covered spandex yarn) and created a line of clothing that would not only make you look slimmer but also improve posture. The confidence Spanx gave to overweight women is exemplary.
So how did Elastane Fibre come into existence. This is a fascinating story in its own. During the World War II, when rubber was used in the equipment used in the war, scientists were burning the midnight oil trying to come up for an alternative for this expensive and unstable natural element. That is how elastane was invented. Elastane wouldn’t react to extreme temperatures and chemicals, and displayed phenomenal stretch and recover properties. It was also extremely cheap to manufacture.
Soon after, elastane was being used in the manufacture of garments. Spandex clothing came to be a rage among Rock artists and enthusiasts– it was shiny, tight and iconic. It was a fashion staple from the 70’s through the 80’s.
Today elastane is used in the creation of fashion and function wear. Intimate wear, active wear, fashion wear, hosiery… you name the category and you’ll find a little bit of spandex, or maybe lots, everywhere!
