plain weave or twill?

From Wikipedia

Plain Weave:

(also called tabby weave or taffeta weave) is the most basic of three fundamental types of textile weaves.[1] It is strong and hard-wearing, used for industry, sails, fashion and furnishing fabrics.

In plain weave, the warp and weft are aligned so they form a simple criss-cross pattern. Each weft thread crosses the warp threads by going over one, then under the next, and so on. The next weft thread goes under the warp threads that its neighbor went over, and vice versa.

Twill:

Twill is a type of fabric woven with a pattern of diagonal parallel ribs. It is also strong and hard-wearing, used for industry, military, fashion and furnishing fabrics.

It is made by passing the weft thread over one or more warp threads and then under two or more warp threads and so on, with a "step" or offset between rows to create the characteristic diagonal pattern. Because of this structure, twills generally drape well. Examples of twill fabric are chino, drill, denim, gabardine, tweed and serge. Thus, twills are often used for sturdy work clothing or durable upholstery because soils and stains are less noticeable on this fabric. Denim, for example, is a twill. The fewer interlacings in twills allow the yarns to move more freely, and thus they are softer and more pliable, and drape better.

Also... “plain weave” is sometimes more associated with the aerospace industry, whereas the ‘twill’ is associated with clear coated items in the automotive world and custom yacht industry. Both have the ‘bling factor’ with deep, rich, 3D effect as the light bounces off the weave patterns.

Money and Currency Handling vs. Ergonomics: When paper currency started along came wallets, bags, clips and other gadgets to help people keep their items organized. As wallets came into fashion so did hip, leg and back ailments. Men would sit for many hours and wonder why at the end of the day they had back, leg, neck, and hip pain; without realizing that the one inch thick wallet they were sitting on was causing all the problems.

Back, leg, neck, and hip pain

Trouble is, all of that plastic stashed in a thick leather wallet can cause lower back pain. How so? For men, sitting down with a thick wallet in a back trouser pocket can damage key nerves. So this is a very common problem. It’s actually so common they have actually named this "Hip Pocket Syndrome" or "Wallet Neuropathy" and one of the solutions to the problem, and I did this years ago, is to replace your wallet with a money clip. I keep my driver’s license, credit cards and maybe a few bills here and it slips in the front pocket so now there is no pressure on that sciatic nerve at all.

One other advantage was that the pick-pocket has a very hard time trying to steal from the front pocket verses the back pocket. Some street vendors like quick access for the front pocket as they need to handle cash quickly and securely.

Many different styles are on the market today; plastic, magnetic, metal spring, leather.  Metal money clips can scratch the magnetic strip, rendering the cards useless, another draw back major drawback is getting through a metal detecting security device; try going to a large sports event, airport terminal, or courthouse, most all metal is now detected by these scanners. Magnetic Money clips can mess with the credit card magnetic stripe and render them useless. Plastic money clips or containers can help provide some protection; however are subject to being either bulky or cheap; or sometimes both.

Today there are quite a variety of clips on the market today. Our company (www.piratecarbon.com) has found the optimum balance of, security, and utility. With a carbon fiber money clip all the benefits are rolled into one, you can go through security scanners without having to take your cards and cash out and placing them where others can see. Also you can rest assured that thieves with ‘skimmers’ wil have a harder time attacking your financial information as carbon fiber naturally deters some frequencies. Another benefit is the hi-tech strength quality of carbon fiber which allows the clamping surfaces to open beyond parallel, without the deformation of normal metal clips. The elegance of a carbon fiber money clip makes for a great conversation piece too, as many people have never seen carbon fiber that goes into the space shuttle, Formula One car, or America’s Cup Boat.

As technology evolves there could be many more styles and variations of money clips as well as commerce and financial tools too. One thing for sure paper money will be around for a long time; so get a carbon fiber money clip.

5 Reasons To Start Using A Money Clip

Do you remember the Seinfeld episode with George Costanza’s wallet. He stuffs it with so much stuff, most of it useless, that he begins to have back problems. He has everything in there from all his major credit cards to receipts to dry cleaning tickets. While extremely funny, there is a lot of truth in that episode.

Wallets have become the male version of the pocket book. We have so many folds, slots and pullouts that we use our trusty wallets to carry the written record of every event in our life. 95% of the things in your wallet are useless. So before you develop a back problem too, here are 5 reasons to start using a money clip instead of a wallet today.

 

 

 

1. Consolidation. Most of the items in your wallet are useless. How about forcing yourself to get rid of them. You’ll have no room for such a waste of space with a money clip. The only things you’ll want to put in your money clip are a few bills and a couple of major credit cards.

2. Style. Money clips are quite simply the cool new way to carry your money. From Hollywood movie stars to corporate executives to pro athletes, money clips are at the forefront of men’s fashion. They are sleek, streamlined and very hip. This isn’t your grandfather’s wallet!

3. Versatility. With so many different styles of money clips on the market today, why settle for a boring wallet. Let’s be honest, every wallet looks the same. Maybe you change the color from brown to black or you add an extra fold but that’s about it. With money clips, you are only limited by your imagination when it comes to style.

4. Ease. How many times have you been fumbling at the checkout counter trying to remove some bills from your bulky wallet? Countless, I bet. Wallet’s are not very user friendly at all. A money clip on the other hand is so easy to use, you’ll have to watch yourself to make sure you don’t spend money too fast! A simple folding of the bills and your cash slides right in and out with a simple tug or push

5. Personalization. Many of today’s money clips can be engraved with your initials, your name, a date or even your company title. Try that with a wallet! Seriously, this is a great way to make a money clip truly yours. Its even better on a gift What better way to show you’ve put thought into a gift than by personalizing it to the recipient.

Still not convinced? Well, I can talk all day about the advantages of a money clip as opposed to a wallet but until you try it for yourself, you’ll never know. That leads me to the final, bonus sixth reason to purchase one. You can find them so inexpensively, that it wont’ cost you an arm and a leg to test one out. You can always upgrade later on but you can pick up a nice inexpensive money clip for under fifteen dollars to test the waters. Trust me, you won’t be disappointed.

The superior properties of carbon fiber to steel and other metals meant that the aerospace industry was an obvious market for composite materials, the use of lighter materials in aircraft construction allows for fuel savings or a greater payload, Carbon fibers are used extensively in both military and civil aircraft structures. As the technology of producing composites advanced, other fibers were developed to supply this market. For example Aramid and E-Glass, see how they compare to carbon fibers:

Material Tensile Strength (GPa) Tensile Modulus (GPa) Density (g/ccm) Specific Strength (GPa)
Carbon 3.5 230.0 1.75 2.00
Kevlar
3.6
60.0
1.44
2.50
E Glass
3.4
22.0
2.60
1.31

 

Carbon fibers are also unique in the range of properties that can be found, in this one generic type of material. As most carbon fiber manufactures are working in a state of constant development and improvement, the range of fibers now available to the structural engineer is always changing, look at the developments of the last 15 years: You might say "what does this mean to me?" - well carbon fiber matrices are about 2 and a half times stronger in the tensile mode, meaning a better spring or clamping force without the risk of deformation, and about one sixth the density, and approximately ten times stronger than steel per given weight. "yes, definitely space age material" - Carbon Fiber now comes to you in the form of a very cool money clip. Try the Stealth Clip TM we are sure you'll be impressed.
