Spider silk healing wound

Several cultures ranging from the Egyptians to the Romans and Greeks to the Irish have  medicinal traditions of using the cobwebs of spiders to dress  wounds, finding this arachnid-based injury dressing and band aid material to help wounds to close and blood to clot. These days we know that this is true due to the high vitamin K content of spider webs, which is a known coagulant.


New research indicate that this ancient medical practice may be beneficial to wound healing for other reasons as well; spider silks may possess antimicrobial and hypoallergenic properties which can help protect a cut from infection and speed up its healing time.

Here is one technique taken from from Mother's Remedies : Over One Thousand Tried and Tested Remedies from Mothers of the United States and Canada by T.J. Ritter, originally published in 1910:
“Make a pad of cobwebs and apply to cut. I have never found anything to equal this remedy.” This simple remedy has been known to save many lives, and can always be obtained. As most housekeepers know; cobwebs are easily found in every home, and perhaps after reading this remedy they will not seem such a pest as heretofore, if we stop to think that at some future date our baby’s life might be saved by using them.
Shakespeare was apparently aware of the medicinal qualities of spider silk, as illustrated in his play A Midsummer Night’s Dream when the character named Bottom said this:
“I shall desire you of more acquaintance, good master cobweb,
If I cut my finger, I shall make bold of you.”

Recycling spider silk

The spider can easily recycle the silk by eating it.
The web is easily destroyed by bad weather and by catching prey. After a day or two the adhesive droplets of glue also lose their adhesiveness. The old web is eaten and a new web is constructed again. The cutting and the digesting of the web are done by special digestive juices that contain enzymes rather than by any mechanical cutting. These juices are also used to connect the strands of silk together.

Amazing gold spider-silk





If you are afraid of spiders , the golden spider you can not seriously scare . These creepy spiders can grow to the size of your palm , for example , some types of spiders have a span of Taiwan clutches of about 13 cm, but no matter how terrible they are, these amazing spiders spin webs up to 1 meter wide and strong enough to catch them snakes , birds and bats even !Spider - golden silk (or banana spider) was so named because of silk , which he uses to build its web. Sunlight yarn shine like gold, thus attracting bees and in the shadows merge with the foliage around the web , making it invisible to the victims of the spider. It is noteworthy also that the spider can change the color of the pigment strand in the process of weaving the web , so Wide Web will be invisible on a light or dark background. Also yarns spun by a spider which contain special chemical compound which repels ants.
 
Remarkably, only females to create a unique one of its kind with a solid web of golden hue . These spiders peculiar sexual dimorphism , where the size of the females at times larger than males. Female body reaches a length of 4 cm , and leg span - all 13 ! Males are almost 5 times less , and the length of their bodies together with spread legs is just 2.5 centimeters.


 All spiders ( not only Spider - golden ) weave a very strong web. Wide consists mainly of proteins containing unusual amino acids alanine many (25 %) and glycine (about 40 %). Portions of protein molecules , rich in alanine to form a tightly packed crystalline regions of the folds , provide high strength, while those areas where more than glycine are more amorphous material capable of good stretch and thereby imparting elasticity filament . Cobweb five times stronger than steel and more elastic than nylon. This is very interesting stuff!
 
It's no wonder that scientists are looking for a way to artificially create such material , and the designer Simon Pearce with entrepreneur Nicholas Godley teamed up on the island of Madagascar in an attempt to create a fabric of spider webs - golden . Within four years , and Pierce Godley with more than 1 million females of golden spider collected spiders web and created a magnificent cloak of web strands . Simon Pearce says that the fabric is so light that it seems that you are wearing the cloak . And do not worry , no one was hurt when a spider making this cloak !



General description of the golden spider

Scientific name: Nephila (from the Greek. Νήμα + φίλος, «loving weave").

Occurrence: Australia, Asia, Africa, Madagascar, America.

Toxicity: Poison spiders of the genus Nephila strong, but not lethal to humans. Bite causes local pain, redness and blisters, which usually disappear within a 24-hour interval. In rare cases it may cause allergic reactions, and asthma, and have trouble breathing.

bulletproof vest from spider silk

American military officers and police in order to wear heavy protective vests diehard capable of providing an adequate level of protection. Madagascar spider silk but is 10 times stronger than Kevlar , the material used in most body armor .
If you could invent a method of producing spider silk on an industrial scale , then it would be bulletproof vests made ​​of heavy-duty , lightweight material that can reliably protect the body from bullets and shrapnel.
After a few decades from the moment when the first experiments were carried out in this field, scientists have finally a real opportunity to find a way to make a protective vest of spider silk .
Besides the fact that this idea looks very innovative , it also implies that the soldiers and police officers will be equipped ultra-light and heavy-duty flexible body armor capable of effectively resist bullets , falling into the housing body. Now American soldiers wear heavy bulky constraining movement remedies . Usually it is extremely heavy jackets with at least two ceramic plates , designed to protect against fragments of grenades and bullets upper body of a soldier.

Spider silk

Spider silk - an extraordinary material . One of its features - a huge strength. Silk thread thick pencil can stop a Boeing 747 flying at full speed. We are still unable to reproduce this material , in spite of all our technological advances . There are several spider glands located in the abdomen, which produce spider silk. Each gland produces silk for a special purpose . Known seven different glands. But different species of spiders have only a few of these glands, and not all at once .



     
Cancer known as Glandula Ampulleceae major and minor are used for the production of silk threads to move. Glandula Pyriformes used for production of fibers for attachment . Glandula Aciniformes produces yarn for sealing production . Glandula Tubiliformes produces thread for cocoons. Glandula Coronatae used to produce sticky strands.



     
Usually spider has three pairs of spinnerets (spinners). But there are spiders with just one pair or even four pairs of spinnerets (spinners). Each spinner has its own function . In the spinners are small tubes that are associated with glands. Number of tubes varies from 2 to 50,000.



 Application of spider silk

     
Spider silk is used for several purposes. Poleniziyskie fishermen use gold thread spider Web Spider (Nephila) as a scaffold . In New-Hebrides spider webs were used to make network for transporting arrowheads , tobacco and dried poison for arrowheads . Some tribes in New Guinea used the network as a hat to protect the head from the rain.



     
In the First World War thread Araneus diadematus, Zilla atrica, Argiope aurantia and other orb weaving spiders were used as instruments in the crosshairs .



     
In 1709, Frenchman , Bon de Saint-Hilaire, demonstrated the possibility of creating fabric from silk. Set cocoons were washed, dried and was then combed yarn . Fired several socks and gloves . Economic feasibility showed that it is not profitable . It has been calculated that in order to produce one kilogram of silk cocoons need 1.3 million spider.



     
In Madagascar, there were some attempts to use spiders Nephil for silk production . Thread manually pulled out of the spinnerets (spinner) spider. After depletion of the spider , he was let go in the woods , and took up the next . Assembled silk had a beautiful golden color . This project was also banned due to many problems. At present, attempts are underway to produce silk artificially.

Silk Carpets

The term "carpet" comes from Old Italian carpita, "carpire" meaning to pluck.The term "carpet" is often used interchangeably with the term "rug". Some define a carpet as stretching from wall to wall. Another definition treats rugs as of lower quality or of smaller size, with carpets quite often having finished ends.
Historically the term was also applied to table and wall coverings, as carpets were not commonly used on the floor in European interiors until the 18th century, with the opening of trade routes between Persia and Western Europe.

   The rugs are knotted in wool based on a silk foundation which gives the rug strength yet flexibility while allowing for tighter, more accurate knotting.
Some rugs, particularly those from Kashmir can be made from silk on a cotton foundation, these tend to be larger pieces with lower knot counts. The idea being that a person can have a large rug made from silk without the need to spend tens of thousands of pounds. These rugs will tend to have a knot-count similar to a fine wool on cotton rug, meaning it will take the same time to weave. Any additional costs are only made from the more expensive materials used.
Full silk rugs are the most expensive on the market. Not only are the materials used in making the rugs costly, but the nature of a 100% silk rug means that more often than not the design is particularly intricate; this means more time is spent weaving a silk rug than a wool rug of similar size. A typical high quality Persian or Oriental rug made in wool might have between 140 and 300 knots per square inch - a high quality silk could range between 450 and 900 KPSI - that's 2-3 times the number of knots than its wool counterpart. Weaving the rug will require 2-3 times the amount of work which becomes more skilled the more intricate the pattern becomes; meaning at least 2-3 times the price!
Some of the finest silk rugs can have more than 1,000 knots per square inch but are extremely rare and cost in the tens, if not hundreds of thousands. 


Flat-weave carpets

Shadda

Shadda is a flat weave carpet, made primarily in Nakhchivan, Agdam, Gubadly, Agjabedi. The artistic composition of shadda made by complicated whipping, as well as its constituents have a complex form. Early in the 20th century the oldest weavers and carpet experts called this type of carpets “shadra’ or “shatra”. The word “shadda” is a distorted form of “shatranj” and “shadvard”. Shadda comes in a number of varieties, each having a specific technique such as monochrome, checkered or subject. Monochrome shadda are made by the simple interweaving technique. Shadda with a checkered pattern is based on the palas and jejim principle. The same technique is used to make subject-based shadda. The subject shadda “Davali” are famous all over the world. They use practically one and the same subject with the composition being almost invariable: the camelcade moving along the carpet field from left to right, along a few horizontal rows, and each string running into a figure of a sarvan on foot. The humans and animals are set off against the dark-red field, its color is smooth and hot.
Azerbaijani carpet centers.

Verni

The most widely spread type of the flat-weave carpet is “verni”. Perhaps none of the flat-weave carpets can boast such a monumental pattern and harmonious clarity as the “verni” made only in Azerbaijan. The technical perfection and utmost emotionality of these carpets is a sort of acme of the Azerbaijani carpet art. Sample “verni” displayed in various museums throughout the world present the outstanding monument of the richest heritage of the Azerbaijani folk art in which we by right take pride. Among the “verni” centers were Agjabedi, Barda, Agdam, Nakhchivan. The key décor feature, which is intrinsical to every ”verni” is the S-element. Its shape varies, it may resemble both figure 5 and letter S. This element means “dragon” among the nomads and “water” among the village people. Based on the stories told by the oldest Azerbaijani weavers with nomadic roots, a dragon featuring carpet would protect the family from foul weather. In Taoism, a dragon is associated with spring. The Tibet pantheon considers dragon as a good deity, a master of chiefs. If the S-element takes up the whole of the carpet space, it would be viewed as an image of a dragon itself rather than a dragon symbol. This element has been known to the local weaver for centuries and is characterized by an ability to come alive through embodiment in a specific image and to symbolize the good and happiness.

Jejim

Jejims are woven on simple horizontal looms by narrow stripes 30–35 cm wide and 15–10 cm long. The resulting product is a cloth to be used as a wall carpet, a bedding coverlet, or curtains. The width of a jejim matches the distance between the weaver’s feet as in the process of weaving the whole width of the cloth should pass through the weaver’s feet. The ornamental décor of jejims is diverse and rich. Various vertical stripes that decorate jejims are spectacular, colorful and decorative. They are often decorated by stylized images of utensils (comb, thread, candlesticks) and geometrical elements. Up to the mid 20th century delicate jejims were used to make garments both for men and women. The major jejim production centers are Barda, Nakhchivan, Zangilan, Shusha, Shamakhy.

Zilli

Carpet Zilli “Zilli” is an interesting variety of flat-woven carpets. They are characterized by stylized forms of animals and vegetal elements. In terms of their composition and pattern the Azerbaijani zillis are very diverse. They feature a plastic flexibility of the pattern and emotional expressiveness. The ornamental decoration is marked by images of large elements in the shape of big lozenges, paired horns, various stylized elements. There are “zillis” with a variety of compositions, which differed by peculiar vegetal ornamental patterns and overall rich colors. The key element in such compositions lies in the recurring alternation of colors along the horizontal pt vertical lines, which form an energetic rhythm. As to their technical and artistic qualities, “zillis” are rich in moving images of stylized birds, elaborated “butas” and other elements. “Zilli’ were obviously influenced by the tendency to fill in the space by various motifs, each being repeated in the field according to its individual layout, and the overall result resembles a fancy garden with a rich and fairy-tale flora.

Kilim

Kilim is the most widespread type of flat-woven carpets. They are made by passing the weft through the warp using the technique of compound interweaving. Kilim is characterized by a slot-like gap (opening) around the geometrical patterns. These openings impart a lace effect the kilim. The technique of kilim weaving predetermines the pattern shapes in the form of a lozenge, triangle, trapezium. Nearly all the vegetal elements, images of animals, birds and humans are geometrized in kilims. Kilims of different regions are distinguished by their composition, pattern, and colors. In terms of their technical peculiarities kilims can be classified into five major groups based on the area of production: Kazakh, Karabakh, Absheron, Shirvan and Tebriz kilims. They are all characterized by a balanced composition, contrasting colors and clear symmetry. The patter is traditional, in the form of large and small lozenge and hook-like elements, which are rather expressive and dramatic.

Sumakh

The “Sumakh” carpets present one of the interesting types of flat-weave carpets, which have become widely spread and recognized over the last few centuries. Beginning with the 18th century “Sumakhs” have been made in the Kuba nd Gusary districts. “Sumakhs” were created much later than other types of flat-woven carpets. In the early stage of their development they might have had their own individual composition, but the “Sumakhs” of the 18th-20th centuries reproduce the compositions and patters copied from the pile carpets made in Shirvan, Kuba, Karabakh and Ganja. The technological peculiarity of “Sumakh” lies in their rich composition and colors. The diverse stylized vegetal motifs, various geometrical elements such as large hexahedral, square, rhomboid medallions impart festive beauty to “Sumakh”. The traditional pattern includes the minor edge with a wave-like pattern, which is called “dolan-gach” (pass around - run away). It is used basically in all “Sumakh” type carpets.

Palas

Palas is one of the widely spread flat-weave carpets. The palas weaving process consists in passing the weft through the warp by a simple technique. The weavers decorate the palas by traditional patters in the form of horizontal stripes commonly used throughout Azerbaijan. But every individual weavers had their own choice of composition and colors. Changing the stripe size the weavers changed the correlation of colors, thus creating countless variations of fine palases. As a rule, the palas is not framed by a border. The palases called “chiy” are made by a very unusual weaving technique. Similarly to other simple types of palases the background of “chiy” is plain weave . At the same time, the pattern-making thread is used to create a fine tiny geometrical pattern by piercing “sanjma”. This creates the embroidery effect.

Kalagayi

The region of Sheki, in Azerbaijan has been trading silk along the silk route for centuries. Prized for its quality, it has been traded for glass in Murano, Italy and has been used by Yves Saint Laurent in Paris.

Artist Kelagayis are handmade by artisans in Sheki using natural local silk. Using patterns that have been carved out of wood the design is manually put on the silk and dyed using natural dyes.
