Netmark is a Danish net and twine supplier with many years of experience. Netmark manufactures a range of twines in different materials: Nylon, Polyester, Dyneema® and Polypropylene. Depending on the purpose of the twine, they are delivered as braided, twisted, spiral braided, round braided or cross braided. All twines are manufactured with the focus on high quality and professionalism.

Netmark has existed since 1995 and has many years of experience with manufacturing nettings and twines. The production takes place in Taurage Litauen and the headquarter is located in Frederica Denmark together with the sister company Dynamica Ropes, which manufacture unique rope solutions made with Dyneema® fibers. Both Netmark and Dynamica Ropes are established and developed by Joergen Sorensen, who is CEO today.

 How to define a twine?

There are different ways to define a twine, but one way is: “ A strong thread or string consisting of two or more strands of hemp or cotton twisted together.”

Netmark manufactures twines like defined above. Netmark’s sister company, Dynamica Ropes is, on the other hand, specialized in ropes from 2 mm up to 120 mm. Dynamica Ropes is mainly manufacturing rope made from Dyneema® and is specialized in unique rope solutions. An example of a unique rope solution is Dynamica SafeLift slings for lifting of 3D structures for offshore wind farms. A lifting operation which requires easy handling slings, since two persons must be capable of handling the lifting sling at a height of 50 to 60 meters.

 

What is nylon fibers?

Nylon is a silky material, which is thermoplastic and can be melted into fibers, films or shapes. Dr. Wallace Carothers was the man, who discovered the nylon material, which was the first synthetic fiber in the world. Nylon became the most successful product, which the American company DuPonts invented. The first sample of nylon was called “nylon 6,6” and was manufactured using diamines in 1935.

First, in 1938, nylon was used commercially for a toothbrush. After this, the next product, which was lanced, was the famous women’s stockings, which also were called “nylons”. At the time when World War ll was going on, nearly all production involving nylon was used to produce parachutes and parachute cords for the military.

Today nylon is among other things used for nylon fishing twines manufactured by Netmark. The Danish net and twine company manufactures a range of other fishing twines, but nylon fishing twines are properly the most common and used twine.

 

What is Polyester fibers?

Polyester is a synthetic fiber derived from coal, air, water, and petroleum. Polyester is developed in the 20th century by a chemical reaction between an acid and an alcohol. The polyester material is used for a range of different products for example home furnishing, high-quality wood products, clothing, bottles, and films. The list of products with polyester is long and Netmark can add manufacturing of nettings and twines made of polyester. All Netmark products are manufactured of high-quality raw materials and handled by a well-educated staff with many years of experience.

 

What are Dyneema® fibers?

Dyneema® fibers produced by DSM in Holland are also called Ultra-High Molecular Weight Polyethylene (UHMWPE). Netmark receives the Dyneema® as fibers but they also come in fabric, tape, and unidirectional sheets. Dyneema® fibers are extremely strong and have a low weight which makes twines and ropes made with Dyneema® ideal for a growing range of different applications.

What are Polypropylene fibers?

Polypropylene or polypropene which the thermoplastic polymer also is called is just like Polyester and Dyneema® used for a wide variety of applications such as packing, plastic parts, labeling, stationery, textiles, loudspeakers, laboratory equipment and polymer banknotes. Netmark is manufacturing both nettings and twines of Polypropylene, which is the world’s second-most widely produced synthetic plastic, after polyethylene. If we look at the year, 2013 the global marked of polypropylene was approximately 55 million tonnes.

In 1951 Robert Banks, who was a chemist and his colleague J. Paul Hogan, who also was a chemist polymerized propylene. First, in 1954, propylene was polymerized into crystalline isotactic and this finding started a commercial production of isotactic polypropylene.
