Du Pont Kevlar Aramid Industrial Fiber (Abridged) Essay

WeaveTech, formally known as Johnson-Ware is a military and security apparel company entering into the high-end performance clothing market. Before the acquisition by CVX Partners, WeaveTech which was formed in 1905, relied exclusively on the military (70%) and security (30%) customer base. The need to change the company’s customer base from military and security to high-end performance clothing market apparently arose from the allure of the later market segment and the dwindling growth of the military and security market (Beer & Swiercz, 2015). The departure of Jack Davidson, a retired US Navy Rear Admiral, and WeaveTech CEO from 1983 to 2012 in addition to the conclusion of the Afghanistan and Iraq Wars meant that the traditional market was losing its reliability. Due to the unreliability, there was a need to redesign the customer base and to take advantage of the high-end market segment.

Having identified the target market of their products, Patagonia was also able to more effectively develop innovative new products. Knowing that their core users wanted high performing fabrics and that they were willing to pay for it, Patagonia was able to make the necessary investments to develop superior fabrics over longer development cycles than their competitors. The new innovations in fabrics and materials trickled down from the higher end lines like Alpine, allowing Patagonia to add value across all their lines and maintain a high price point.

NLJ produces and sells two lines of jackets: nylon and leather. The market for nylon

World War Two's most famous contributions to the history of body armor is the flak jacket. Made from ballistic nylon, the flak jacket was "cumbersome and bulky" and "was ineffective against most pistol and rifle threats," (Bellis, n.d.). However, flak jackets were very effective in preventing casualties related to shrapnel. Shrapnel did account for as much as 70% of all Second World War casualties (Pike, 2011). No significant advancements in body armor were made between the end of World War Two and the 1970s. Even during the Vietnam War, flak jackets were still being used. In the 1970s, though, Kevlar was invented. Kevlar and other lighter weight materials allowed for constant protection that was relatively comfortable to wear. Moreover, the improved materials could protect greater surface area on the body. As Pike (2011) points out, "Most fatal penetrating injuries were caused by missiles entering through areas not protected by body armor, such as the face, neck, pelvis, and groin." Unlike earlier materials, Kevlar also

The two molecules on the left are the chemicals that reacted to make Kevlar, which is the molecule on the right. Kevlar can be grown to different lengths so when people manufacture it, it can be fine tuned to a specific standard depending on what the intended use is for. This makes it so there are many different Kevlar grades that you can purchase and use. The chemicals used to make Kevlar are polyparaphenylene terephthalamide and terephthaloyl chloride. After this reaction is finished, the polymer that is produced is spun into strong, thick fibers. This polymer is extremely strongly bonded, and each strand is bound together by hydrogen

My unknown fiber is cotton. Cotton is the number one fiber used for apparel in the United states. In a study from 1994, sixty three percent of cotton was used for apparel. Cotton makes great clothes because it is a good insulator, it absorbs perspiration, is very comfortable, and is durable.

She eventually went to the women’s college of Carnegie-Mellon University (Margaret Morrison Carnegie College.) After her graduation, she applied for a position as a chemist for the DuPont Company. Kwolek’s interview with W. Hale Charch, who had made the process to make cellophane waterproof and was, by then, a research director, is an important landmark of her life. After Charch let her know that he would tell her if she was to be offered a job later, Kwolek strongly asked if he could make a decision sooner, because she had another offer that she had to reply to soon. In Kwolek’s presence, he gave her an offer letter. She later reflected on this, stating that if it wasn’t for her harshness, she probably wouldn’t have gotten the job. After working for DuPont for numerous years, Kwolek, in her 40s, was asked to find the next generation of fibers capable of performing in extreme conditions. She unexpectedly discovered that under certain conditions, large amounts of the molecules of rod-like polyamides form liquid crystalline solutions, and that these solutions can be spun directly into shaped fibers of very high strength and hardness. It was after this that she invented Kevlar using this

A bullet proof vest consists of a vest-shaped panel made up of advanced plastic polymers that are composed of many layers of Kevlar or Spectra shield. The layers of Kevlar are sewn together using Kevlar thread but the nonwoven spectra shield is coated and bonded with resins such as Kraton and sealed between two sheets of Kevlar. Once all of the panels of Kevlar are sewn together it is placed inside of a fabric shell that is usually made from polyester and cotton blend or nylon. A bulletproof vest may also have nylon padding for extra protection. If the bullet proof vest is intended to be worn in especially dangerous situations puches are built in to hold plates of metal or ceramic bonded fiberglass.

CornelCookson is a leading manufacturer of overhead coiling doors and custom closure products. One of their most popular products is the steel slated rolling steel door (see Figure 1), which is used to provide security and weather protection across a wall opening of a building. An astragal (see Figure 2), which is a weather seal, is supplied at the bottom of the door to help prevent the transfer of fluids from one side of the wall to the other. The current material of the astragal is Thermoplastic Vulcanizate (TPV), which is composed of 40%

To begin with, although they will have a new fabtic supplier, it does not necessary mean that they will have a reliable and sufficient source of wool fabric. Clearly, the author assume that the new provider can offer proper raw material and the conpany can still produce it. However, it is highly likely that the company's facilities are to outmoted to produce new alpaca overcoats or the efficience is influenced severely. What's more, there is no evidence that the new fabric supplier is better than the former one. What if their material is worse than those five years ago？What is their ability to offer wool fabtic? Lacking substantiating evidence for cases, the author can not convince me the proposed suggestoin is plausible.
