Production of spandex uses nitrogen, solvent gas, macroglycol, diamine etc. What damage can be caused to the environment during this process? What precautions should be taken during this process?

Our goal is to create long-term value for our customers and society by using resources more efficiently; protecting the environment and the safety and health of our employees and others; consistently applying good science; and employing Market Based Management. In all of our elastane manufacturing operations, we seek ways to reduce our environmental footprint by conserving resources, reducing emissions and eliminating wastes. For example, our Maydown Plant in the United Kingdom, has reduced the amount of fibre waste going to landfill from 7 per cent in 2007 to less than 1 per cent of production today and our Paulina Plant in Brazil has reduced water intensity by 23 per cent from 2003 through 2011 and has had no lost time incident for more than 38 years. We are committed to reducing its energy intensity 20 per cent by 2020, through optimising its current energy practices and capital investments.

Which countries are best in terms of government policies that facilitate the production of fabrics?

We have customers in all the major textile regions and countries around the globe and feel privileged with the ability to work with them and supply them our fibre. We offer to work with all our customers to help them establish their own position of fabric quality, cost and value/differentiation when it comes to stretch fibres and we have customers that are successful with their business strategy and positioning around the globe. As a fibre supplier, we are not necessarily connected to all the details and subtles of fabric sourcing dynamics around the globe and leave that to our customers.

What is the relation between spandex consumption and fabric weight, fabric width and elastic behaviour of the knit fabric?

Typically, the higher the spandex content or consumption in a fabric, the heavier the fabric weight and the higher the modulus, all other factors (knit construction, heat-setting, dyeing & finishing) being equal. A higher fabric modulus, improves the recovery power and efficiency of fabrics, which is especially important for shapewear and athletic wear. You will find Lycra fibre in lightweight fabrics for lingerie (100+gms and typically 10% elastane content) to heavier denim fabric (300gms and 2% elastane content), but with the innovation we are seeing in fabric constructions, machine technology and fibres, today you can find a 120gms fabric with 50% Lycra fibre content, targeted the lightweight shapewear market.

What is the difference between the spandex fabrics used by luxury innerwear brands compared to the ordinary ones?

Although we produce over 25 types of Lycra fibres and hundreds of SKU’s they are differentiated more by their features, attributes and intended garment category and not necessarily by the price point of the final retail garment. As an ingredient, the role of LYCRA fibre is to add, comfort, fit, freedom of movement to all fabrics and garments, and the other materials used in the fabric and garment construction, coloration and design are often what create the difference between various brands.

How Lycra can be efficiently used in shape wear?

Lycra Beauty fabrics are designed to improve the effectiveness of shapewear and expand the range of options available to women who want that secret advantage. Lycra Beauty fabric is the secret asset to shapewear that delivers what you want...sculpting, smoothing, comfort, style, quality, confidence. This fabric collection is the foundation for silhouette enhancing garments with the versatility to range from firm control to featherweight smoothing, from understated elegance to high fashion drama. Its fabric collection is segmented into four categories which provide solutions for the diversity the market requires and helps our customers to easily identify which fabrics are ideal for their needs. The four categories are: -Smoothing -Sensual Curves -Sculpt -Control Shapewear is a fast growing category – both in volume and consumer relevance. We conducted a global consumer study that confirms that nearly all women (93%) show interest in the shaping attribute when purchasing intimate apparel. Whatever their age or body shape, women want truly performing garments without compromising comfort, that they can wear on special occasions or every day, year-in, year-out. These fabrics are engineered to meet extremely demanding standards that can create new solutions for shapewear that satisfies the expectations of this changing category.
