Mooring ropes connect a vessel to the pier. Tension on these ropes can change rapidly as a result of tides, swells, and changes in the ship's draft due to cargo handling operations. Normally, sailors adjust tension manually, but it is extremely challenging to adjust it in response to rapidly changing real-time weather and sea conditions. A smart mooring rope with a built-in sensor cable that can measure tension and stretching of the rope is developed and in trials phase.

Mooring Rope​

A mooring rope is a rope or cable used to secure a boat or ship to a dock, buoy, or anchor. It is typically made of a durable material such as nylon or polypropylene and is designed to withstand the forces of wind, waves, and currents. Mooring ropes come in a variety of lengths and diameters to accommodate different types and sizes of vessels.

Introduction:​

When it comes to staying comfortable during physical activity, the type of clothing you wear can make a big difference. Sportswear is designed to regulate body temperature and keep the wearer cool and dry, but how does it work? In this blog post, we'll dive into the science of thermoregulation in sportswear and explore the key factors that contribute to thermal comfort.

Butterfly wings are covered in scales that are made of a protein called chitin. These scales give butterfly wings their color, patterns, and texture. The colors of butterfly wings are created by the reflection, absorption, and transmission of light by the scales, pigments, and structures on the wings. The patterns and shapes of butterfly wings are determined by the arrangement and interaction of these scales, pigments, and structures. Some butterfly species have wings that are specifically adapted for camouflage, courtship, or thermoregulation. https://www.tandfonline.com/doi/full/10.1080/15440478.2022.2164107

Chitin ​

Chitin is a natural polymer that is found in the exoskeletons of crustaceans, insects, and other arthropods, as well as in the cell walls of fungi. It is composed of repeating units of a sugar called N-acetylglucosamine, linked together by glycosidic bonds. Chitin is the second most abundant biopolymer on earth after cellulose. The use of chitin has been explored for various applications such as wound healing, drug delivery, tissue engineering, agriculture and food industries, cosmetics and personal care, environmental applications and more

Chitin Fiber​

Chitin fiber is a natural polymer fiber derived from chitin There are several methods of producing chitin fibers, including mechanical, chemical and enzymatic methods. The most common method is the mechanical method, which involves grinding the chitin-rich shells of crustaceans into a powder, and then spinning the powder into fibers using a spinning machine. In chemical method, chitin is dissolved in a solvent, and then spinning the solution into fibers, this method can be used to produce chitin fibers in large amounts. In enzymatic method, chitin is first deproteinated by removing the protein content and then the fibers are produced by using the enzyme chitinase.The resulting fibers are strong, flexible, and have good moisture-wicking properties, making them suitable for use in textiles, such as clothing, bedding, and other applications.It is worth to mention that the production of chitin fibers is still a research area, it is not yet fully commercialized

Why Chitin Fiber​

Chitin, as a fiber, offers several benefits over synthetic fibers and other natural fibers such as cotton and wool. Some of the main benefits are:

• Biodegradable: Chitin fibers are biodegradable and therefore do not contribute to the pollution caused by synthetic fibers.
• Biocompatible: Chitin is a natural material that is biocompatible, which means it does not cause any adverse reactions in the human body, making it safe for use in clothing and other applications.
• Strong and flexible: Chitin fibers are strong and flexible, which makes them suitable for use in textiles, such as clothing, bedding, and other applications.
• Moisture-wicking properties: Chitin fibers have good moisture-wicking properties, meaning they are able to absorb and transport moisture away from the skin, which can help to keep the wearer cool and comfortable.
• Antimicrobial and anti-inflammatory properties: chitin and chitosan fibers have been shown to have antimicrobial and anti-inflammatory properties, which can help to keep the wearer healthy and reduce the risk of infection.
• UV-protection: chitosan fibers have been reported to have UV-protection properties, which can protect the skin from the harmful effects of UV radiation.

Hope you learned something new. Till next time take care, wear mask and #SwachhBharat

Devan Chemicals based in Belgium have developed a microencapsulation finish to help people against allergic reaction to dust. Let's dig into it.

When creating a bulletproof vest, it's important to consider a number of variables, including the best bullet-resistant materials to use, the correct level of protection, and how well-fitted and comfortable the vest will be for the wearer. The steps that are normally taken when constructing a bulletproof vest are as follows: 

In the previous post, we discussed the use of Glass fabric and more specifically Glass PTFE fabric as a hot gas filtration media in power plants. These fabric filters are commonly referred to as Baghouse filters.

In a coal-fired power plant, flue gas is produced when coal is burned to generate electricity. The flue gas typically consists of a mixture of gases, including carbon dioxide, water vapor, and nitrogen, as well as small amounts of other pollutants such as sulfur dioxide, particulate matter, and heavy metals.

  So in this series of articles / blogs we have discussed various factors which have influence in determining the thermal protection performance of a protective fabric and subsequently clothing.

The specific heat capacity of a material is the amount of heat energy required to raise the temperature of a unit mass of the material by a certain degree. Different materials have different specific heat capacities, which can be affected by factors such as their chemical makeup and microstructure.
