Lycra (Spandex) is softer and has greater stretch capability allowing for more flexibility. Its fabric has a rubberized elastic material. This is especially important for Synchro Swimmers. However due to the rubberized elastic material Lycra tends to breakdown earlier than Polyester because the chlorine attacks the rubberized elastic material in the fabric.

Latex caps are very inexpensive. They do not last very long. They can pull on hair or be uncomfortable. Silicone caps are more expensive but last longer and may be more comfortable. Both latex and silicone caps will keep the hair relatively dry. They may help keep goggle straps from slipping. Lycra caps are the most comfortable and do not pull hair. They come in many colors and patterns. Lycra caps are not waterproof and only serve to keep longer hair from swishing around. See similar questions...

The difference is primarily the thermal and chemical compatibility. Traditionally the polyester is used on steel ring bags and polypropylene on the plastic flange. Our 100% polypropylene filter bag is manufactured from FDA compliant material for food grade applications. back to top) Why does my filter bag seem longer than my support basket? Filter bags are basically a two dimensional flat tube with a collar. It must fill up void spaces of a three dimensional support basket. See similar questions...

Polyester rope is bright white where as cotton rope is more of a beige color. Polyester rope will last longer outdoors then cotton rope. Some people say that cotton rope is more comfortable then polyester. This is largely a matter of opinion. See similar questions...

Polyester is a man-made fabric which results in a garment which is extremely light and comfortable to wear, with excellent quick drying and chlorine resistant properties. Polycotton is a more natural fabric and feels more like the t-shirts that you put on your children. This is ideal for infant or sensitive skins, but takes a little longer to dry than polyester. Both fabrics achieve the same SPF of 50+ and fit in the same way. See similar questions...

a) Acetate: Acetate provides excellent drapability and softness, and is moth resistant. Acetate is dry-clean only. b) Polyester: Polyester is strong; moth resistant; resistant to stretching, most chemicals, and abrasion; is crisp and resilient when wet or dry; retains heat-set pleats and creases; is more wrinkle resistant than Acetate; and is easily washed in ordinary washers and dryers.

Polyester films, like USI OptiClear, are clearer and a higher quality than lower grade films, which tend to be foggy. Premium films also endure extreme environments and severe stress conditions more favorably. Films with higher polyester content are more rigid and feel thicker than films with more adhesive content. Polypropylene film is softer than polyester, but still has excellent clarity. See similar questions...

They are not recommended for use in high humidity or exposure to water, as volume swell and reduction of properties may result. Because of inherent advantages in low heat build-up, polyether-based urethanes are recommended for applications undergoing medium to high stress. See similar questions...

Yes. The material has no negative effect on health. It causes no itching or skin irritation. Heat-welded polyester does not release fibres into the air (which is a cause of medical concern). This is one reason why many hospitals and buildings with air-conditioning systems choose NOVAtherm and NOVAhush. See similar questions...

All fabrics of Instride riding apparel contain at least 10% Lycra, with four way stretch. This insures a comfortable fit without binding, yet maintains its shape wearing after wearing. All fabrics, & the solid color ultrasuede?, may be machine washed in cool water, and placed in a cool dryer. For BEST results, turn the clothing item "inside out" before washing and drying. Wash like colors together and NEVER use bleach directly on the fabric. See similar questions...

Yes and no. The idea was born years ago, long time before I found similar clothes on the Net. However, these clothes have been made independently of me as well :) See similar questions...

All the materials I use are certified for sportswear, so they breathe good! Except PVC-coated fabric that I don't recommend for activewear. And there's no report of allergy that I know of. See similar questions...

Laminating resin is greenish blue in color and is the basic first coat of resin; it is used to adhere the cloth to the blank (this resin will only dry tacky and not sandable!) Sanding or hot coat resin or filler coat is almost the same thing; it is lam resin with surfacing agent (styrene monomer and paraffin wax) mixed in. Paint it on the laminated surfboard to fill the fiberglass weave and make the board sandable. Gloss/finish Resin is pink in color and is the final coat of resin. See similar questions...

I prefer handwash or automatic washer with "delicate" program: warm water (near 40c) and some neutral detergent with NO chlorine or bleach, like ones used for kids' clothes. Please buy a washing bag (used widely to wash legwear) and always close all the zippers on the suit, if you're using a washing machine. Never use dryers or fans - let the suit dry on the air, and preferrably in horisontal position... That's all! See similar questions...

Simply Spray will work on silk, but it will not have the same affect as it will on cotton. Simply Spray will run on silk or polyester, leaving a more tie-dyed look. So, yes, it will work, but won't be as controllable as it is on 100% cotton. See similar questions...

Use no more than a ratio of 10% by volume of the Styrene Monomer for thinning, as higher concentrations will degrade the resin's properties. Do NOT use with epoxy. See similar questions...

Polyester is man-made and the properties can be changed. Many articles of clothing now include polyester. Fleece jackets keep you warm, raincoats repel water and wicking polyester that absorbs moisture. The threads of the polyester used for Coolfemme products have been restructured to make them wick or draw moisture away from your skin see our fabric page. See similar questions...
