What is kapron? These are polyamide synthetic fibers that a person has learned to obtain artificially. Kapron became widespread in the last century. In women, this synthetic material is associated with tights, and men come up with fishing tackle made from durable nylon fibers.
Composition of kapron
Polyamides were one of the first synthetic fibers that received enormous practical application both in everyday life and in industry. One of the main reasons for their wide distribution is the strength of the material, resistance to mechanical stress. Polyamides are what kapron is made of.
Using
In different countries, this material was called differently. People of the older generation will probably remember all kinds of kapron products that were very popular in the 70-80s of the last century (bologna raincoats, kapron scarves and stockings, curtains).
Nowadays, kapron is often used in combination with other materials or fabrics made from natural fibers. All this provides high strength characteristics, reduces the cost of production, making it affordable. This contributed to the widespread use of kapron in the home and industrial sectors. It is used for the manufacture of nylon cords, ropes, nets, which are ubiquitous.
History of creation
Experiments on the interaction of polymer compounds from petroleum products and anthracites were carried out in various countries around the world at the very beginning of the last century. Initially, the amide group polymers were synthesized in 1932 by American scientists. The resulting experiment material was called nylon. However, later, six years later, a similar material, called perlon, was obtained in Germany. In 1942, Soviet scientists also received material similar in characteristics to nylon - it was kapron.
Capron Properties
So what is kapron? Kapron fibers have increased wear resistance characteristics: they have a high threshold for wear, bending, compression and tension both in dry and in wet form. They also have increased resistance to solvents and chemicals such as alkalis. However, they have low stability when interacting with concentrated acids, they dissolve in cresol, as well as phenol. Kapron is sensitive to high temperatures, it becomes soft at 175 0 and melts at 215 0 .
One of the main advantages of kapron over other fibers (including natural) is its strength. So, for example, kapron is stronger than silk. However, it has other characteristics:
- elasticity;
- resistance to deformation;
- ease;
- resistance to moisture and water;
- resistance to dirt;
- long service life;
- affordability.
All of the above properties allow you to better understand what kapron is. They caused its widespread use in many industries and in everyday life.
Application
To understand what kapron is from the point of view of practical use, we turn to history. Initially, kapron was used in the production of high-strength cables and ropes, often they were replaced by silk fabric, which was part of the elements of the parachute.
In 1948, kapron began to be produced on an industrial scale, it was widely used in the textile industry and became a very popular material, especially in everyday life. Products made of kapron began to come into fashion, stockings, sweaters, skirts, as well as all kinds of decoration elements for clothes became very popular. All this contributed to the fact that soon kapron began to displace cotton and became a serious competitor to silk. From it began to produce underwear, curtains and other products. Due to his qualities, many fashionistas preferred him, preferring to replace them with more natural fabrics. In the mid-sixties in the Soviet Union began production of fabric "Bologna", which was created on the basis of nylon fiber. Raincoats, jackets and coats were made from it.
However, the popularity of this material soon passed. This is explained by the fact that the material is relatively rigid, does not allow air to pass through well, and also forms static electricity and hardly retains heat. All this showed that kapron is a substance that is uncomfortable to wear. Demand for him began to fall, this contributed to the fact that he began to go out of fashion, giving way to more natural materials.Why do you need kapron today?
In the first half of the seventies, kapron began to displace materials with more advanced characteristics. A huge role here was played by the fact that the production of kapron releases a huge amount of harmful substances, which negatively affects the environment. Now kapron is mainly used where it requires increased strength and resistance to moisture. It is used in the manufacture of filters or packaging materials. The nylon mesh is widely used in the marine industry, fishing nets and gear are made from it .
Quite often, it is also used in combination with other materials, giving strength to clothing and making it more affordable. Kapron fiber is still widely used in the production of stockings and various tights, as well as tulle, curtains and various knitwear, which is used to create outfits for the stage or decoration elements of clothing.
Kapron in the industry
Kapron cord is used in the fishing industry, in the household, in the sailing fleet, in the military sphere, in the oil industry. Also for fixing various loads, packages when lifting them (slings). Kapron mesh is often used in construction, often various walling networks are also made from it.
