Spandex its production and fashion connection

Spandex is used in many different ways in the world and is produced in basically four methods. Melt extrusion, reaction spinning, wet spinning and dry spinning. The name spandex aka Elastane (Europe) has more longevity than rubber. This material was invented by Joseph Shivers at DuPont Company. The word spandex is an anagram of the word expands.                                                 
Dry spinning is the most preferred method for making spandex and is over 94% of the world’s process. All these methods are used with the pre-polymer reaction. Spandex fiber has multiple uses from Apparel to orthopedic applications. Wet suits, swim suits, ski pants, hosiery, leggings, and many other uses. National Aeronautics Space Agency utilizes this fiber for its strength.  Comic book heroes such as batman and robin, Superman, amongst others are also avid users of this amazing material. In the early to mid seventies many rock bands used spandex for comfort and movement on stage because of its elasticity to the human body. During the making of Star Trek and other well known movies, spandex was the desired fabric for the most outrageous clothes made for these top notch scientific thrillers.
In the fashion industry many designers are using spandex cotton mixes in their designs because of durability and fit. JoeyJ maker of Ahimsa silk for ShirtsGoneWild has now 2011 mens casual shirts for this purpose. Most of the manufacturing of these shirts are done in Italy or Croatia where the Ahimsa silk farm is for the mega outlet. It would seem from a retail environment that the needs of the many outweigh the needs of the few. This is typical for the clothing and apparel world.
In conclusion, Spandex will be around for ions simply because it is so versatile and comfortable. Many industries will benefit from this expandable fiber material.

Wool The Fabric of Choice In Fashion



Wool is produced all over the world with the majority coming from Australia and New Zealand. Wool in its natural state has many constituents ranging from oils to dirt. Some of these are called contaminants. The mixture of these elements of good and bad are mainly from years of evolution in sheep. Mainly these are keratins which is basically proteins. Unlike cotton and some other fibers, wool doesn’t have a homogenous type structure at all. They have complex chemical and physical compositions from which have been advancing in time with climatic changes for protection from heat and cold.

Technology tells us that Wool has over 175 proteins. Each of these proteins is not indigenous to one particular area of the wool fiber. This will give the regions in the wool makeup different chemical workloads. The protein in wool is basically made up of amino acids (-nh2) and acidic carboxyl (-cooh). In wool single polypeptide chains join together to form proteins by a variety of chemical bonds which we call crosslinks in the science world.

Once the growth process (keratinisation) takes effect, it becomes much stronger and insoluble to many attacks from external factors. What this means for finishing wool products is more strength and dye ready for fashion industry, for example.

In addition to the chemical nature of wool, the physical aspect of it is much different than other fibers. For example, Australian Merino wool has internal cells as well as external cuticle cells. This relates to strength and keeping dry when wet. Typically this wool is thicker in diameter than most of its counterparts. These cell structures are very dense and are extra padding for the wool fiber. New Zealand has much of its Merino Wool exported for this reason in retail outlets throughout the world of Fashion. Many of the exquisite men’s designer dress shirts are made from the material.

Much of these fibers are spring-like giving it flexibility and pliability. Another reason for a wonderful finished apparel product.  Designer JoeyJ has wool mens dress shirts and some of the finest wool tops for men on the market today for example. Most of these outlets such as ShirtsGoneWild and others are more fashion tuned as to the chemical makeup for an edge in the industry for top notch end result men’s fashion or ladies clothing.

Without doubt Wool is the wonder fabric of the world. It is well known for many millennia to be strong pliable and comfortable. Wool although costly is one of the finest fiber to fashion end products there is on the market today.

Nylon The Most Valued Fabric In Any Industry

Nylon is a thermoplastic material used for many items and combined with heavy duty double treated threads in a vast variety of products throughout the globe. Everything from Fashion to bullet proof vests has the honors of being end products.  Also known as Polyamide, nylon has proven itself to be stronger than most fabrics.                                                                               
First discovered by a DuPont employee as a replacement for silk in WW2, it replaced the silk fibers for parachutes and flak vests. Nylon is now very abundant for a multi-purpose vision many had in mind. Commercial nylon is made simply by combining the chemical threads and melting them into one. Orlon and Dacron are off-shoots of nylon used extensively in the fashion industry. The most popular being Polyester. Everything from shirts to skirts can be seen on many from the disco era of the seventies.
Nylon drastically affected the couture of the French fashion scene. DuPont played a huge role in the industry change. Once the organic fibers became more widely used the nylon material fell a bit off, however many realized other uses for this fantastic fabric. Engineered fibers took hold in the early eighties making competition fierce.
Additionally, the fashion guru’s considered adding polyester to many of the new apparel lines, which added more spice to the industry. New and improved they called it. The fashion houses have made many new modern shirts from the early seventies through the nineties.  Unisex designers made many ruffle dresses and cuffs for the rich and famous as late as 2002.  There are many industries depending on the nylon product for their needs in the current market and will do so for many years to come. More and more end product users have many uses for this valued fabric in more methods of manufacturing than ever before in time.
