⭐ Core Definition: Microfiber

Microfiber (US) or microfibre (UK) is synthetic fiber finer than one denier or decitex/thread, having a diameter of less than ten micrometers.

The most common types of microfiber are made variously of polyesters; polyamides (e.g., nylon, Kevlar, Nomex); and combinations of polyester, polyamide, and polypropylene. Microfiber is used to make mats, knits, and weaves, for apparel, upholstery, industrial filters, and cleaning products. The shape, size, and combinations of synthetic fibers are chosen for specific characteristics, including softness, toughness, absorption, water repellence, electrostatics, and filtering ability.

Microfiber in the context of Van der Waals force

In molecular physics and chemistry, the van der Waals force (sometimes van der Waals' force) is a distance-dependent interaction between atoms or molecules. Unlike ionic or covalent bonds, these attractions do not result from a chemical electronic bond; they are comparatively weak and therefore more susceptible to disturbance. The van der Waals force quickly vanishes at longer distances between interacting molecules.

Named after Dutch physicist Johannes Diderik van der Waals, the van der Waals force plays a fundamental role in fields as diverse as supramolecular chemistry, structural biology, polymer science, nanotechnology, surface science, and condensed matter physics. It also underlies many properties of organic compounds and molecular solids, including their solubility in polar and non-polar media.

Microfiber in the context of Environmental impact of fashion

The fashion industry, particularly the manufacturing and use of apparel and footwear, is a significant driver of greenhouse gas emissions, pollution, water use, and textile waste. During the 19th century, industrialization meant a move towards the manufacture of textiles on a large-scale, which only accelerated the environmental degradation. The rapid growth of fast fashion has led to around 80 billion items of clothing being consumed annually, with about 85% of clothes consumed in United States being sent to landfill.Recent research suggests that despite constituting a small fraction of total apparel volume, methane emissions from animal-based fibres (such as wool and leather) comprise a disproportionately large share of the fashion industry’s greenhouse gas footprint. Indeed, one study estimates that, although wool and leather account for just 3–5% of global fashion production, they could be responsible for 70–80% of its methane emissions over 20 years.

Less than one percent of clothing is recycled to make new clothes. In the late 2010s it emitted 2% of world total greenhouse gases, and contributed to climate change through energy-intensive production. The production and distribution of the crops, fibers, and garments used in fashion all contribute to differing forms of environmental pollution, including water, air, and soil degradation. The textile industry is the second greatest polluter of local freshwater in the world, and is culpable for roughly one-fifth of all industrial water pollution. Some of the main factors that contribute to this industrial caused pollution are the vast overproduction of fashion items, the use of synthetic fibers, the agriculture pollution of fashion crops, and the proliferation of microfibers across global water sources.

Microfiber in the context of Towel

A towel is a piece of absorbent cloth, or paper, used for drying or wiping a surface. Towels draw moisture through direct contact.

Bathing towels and hand towels are usually made of cotton, linen, bamboo and synthetic microfibers.
