Investment Continues for Needlepunch Nonwovens

Despite a slowdown during the early months of the coronavirus pandemic in 2020, needlepunch investment has ticked up in the last 12-18 months. “The needlepunch market over the years has enjoyed a solid growth rate and reacts in a resilient way when disruptive economic changes like in a pandemic are happening,” says J.P. Dilo, CEO of machinery specialist DiloGroup. “The influence of the pandemic prevailed for about six months when investment in new machinery or upgrades were largely stopped. However, already six months later orders started to come in in a highly accelerated way and soon reached or even exceeded...

Enhancing mechanical properties of flash-spun filaments by pressure-induced phase separation control in supercritical high-density polyethylene solution

Flash-spun nonwoven (FS-NW) is gaining attention in the PPE field due to its excellent barrier and mechanical properties resulting from its non-uniform diameter distribution and unique filament morphology. The unique network structure of flash-spun filaments (FSF) comprising the FS-NW can be controlled by phase separation behavior in the supercritical fluid (SCF) process. This study proposes a simple method to control the microstructure of FSFs by controlling the pressure-induced phase separation (PIPS) process in polymer/SCF solution. This phase separation behavior of an HDPE/SCF solution was confirmed by using a high-pressure view cell. A multistage nozzle allowing for phase-separated pressure to form...

Industrial Filtration Market Size is projected to reach USD 59.89 Billion by 2031

The process of removing suspended solid particles from a liquid or gas is known as filtration. This procedure is carried out with the assistance of a medium known as a filter media. The process is used in the chemical and petrochemical industries and automotive, metals, and mining industries. The increasing need to prevent dust and minute airborne particles generated within manufacturing plant space from being released into the environment may drive market demand in the coming years. Increased efforts by major manufacturers to bring about innovations such as reduced greenhouse gas emissions, improved performance, and increased energy efficiency in filter...

How does Bag Filter work ? Structure & Principle

The Bag Filter is a dust control device whose purpose is removing the dust contained in the exhaust gases from industrial process. It is applied to the various applications with different temperature and type of gasses by selecting the filter media accordingly.The advantage of Bag Filter over the cyclone collector is that it can collect the submicron particles. StructureThe Bag Filter separates dust from the exhaust gas by collecting them with the filter media. The dust is accumulated on the surface of filter media. And the filter media is cleaned by reverse airflow called backwashing (pulse-jet).The Bag Filter has a...

Fibers, Textiles And Nonwovens In Filtration

Technical textiles play a major and profitable role in filtration media. A wide variety of fibers, dref yarns, nonwoven fabrics, multifilament and monofilament woven fabrics, and in some cases blends or combinations of more than one of the above, are used in filtration applications. Within this article, dollar amounts are for North America specific to fiber, textile and nonwoven filtration media within the overall the market of nearly $2 billion. Filtration media fulfills a large number of specific uses as well as an overwhelming number of smaller niches that when combined, provides for overall growth at a rate higher than...

Why use nonwovens in filtration?

Nonwovens can be engineered very precisely to meet exact specifications and stringent regulatory requirements for air filtration and liquid filtration. They are ideal in filtration applications where strength of extremely high temperatures is required but other advantages include, ease of strikethrough, increased efficiency, reduced energy cost, and longer service life. One of the fastest growing segments, nonwovens have evolved from simply replacing other forms of media, such as paper, cloth, glass and carbon to becoming the media of choice for filtration, including the wide adoption of nanofiber layers and the use of sophisticated hybrid filter media. The advantages of using...

Application Of Nonwoven In Filtration

In all the manufacturing industries, filtration is an important process in separating the unwanted dust particles during the process. Textile materials play a vital role in the industrial filters. Filtration process consists of two main processes namely filtration and cleaning of filters. Woven, knitted and nonwoven textiles materials are generally used as filter fabrics. Nonwoven material yields better filtration efficiency compared to other materials. Needle felt nonwoven are mostly used as filtration fabrics. Various type of textile fibers are used as nonwoven filtration fabrics depends upon its performances. In this paper, the details about the nonwoven filtration process, use of...

How Does a Die Cutter Work?

IntroductionDie cutting is a process that allows the same shape to be generated uniformly in various materials. These materials include paper, wood, plastic, metal or fabric. The cuts made, called blanks, are just that. These unfinished pieces are not decorated and need to be finished by adding embellishments or decorations. The importance of die cutters is uniformity. Without using a die cutter, it would be a painstaking and timely process to make shapes all the same size, without being irregular. The DieSharp blades, also called rule, are specifically shaped to make a certain design. This bent blade is mounted to...

Non-Woven Fabrics

Nonwovens do not depend on the interlacing of yarn for internal cohesion. Intrinsically they have neither an organized geometrical structure. They are essentially the result of the relationship between one single fiber and another. This provides nonwoven fabrics with characteristics of their own, with new or better properties (absorption, filtration) and therefore opens them up to other applications. Nonwovens are defined by ISO standard 9092 and CEN EN 29092. “A nonwoven is a sheet of fibres, continuous filaments, or chopped yarns of any nature or origin, that have been formed into a web by any means, and bonded together by...

Fact Sheet: Belt Filter Press

Belt filter presses are used to remove water from liquid wastewater residuals and produce a non-liquid material referred to as “cake.” Dewatering wastewater solids reduces the volume of residuals, improves operation, and reduces costs for subsequent storage, processing, transfer, end use, or disposal among other benefits.
