VDMA: Mask production: Nothing runs without textile machinery

  • Protective masks, everyday masks, disinfecting wipes and surgical gowns are goods in demand in times of corona.
  • In their manufacture, textile machines are at the beginning of the production chain.

The production of the textile raw material is the first step of the usually multi-stage production processes. Members of the VDMA Textile Machinery Association are at the beginning of this technological chain.

The production of protective masks starts with the manufacture of the filter material, which for surgical masks as well as FFP2 and FFP3 respirator masks consists of fine-pored nonwoven fabric to intercept coronaviruses. In addition to the systems, machines and components used for this purpose, measurement and control technology ensures the highest quality of important parameters such as basis weight and air permeability. Nonwovens used for respiratory masks have to meet the same high-quality requirements as the masks – to ensure the protection of the mask wearer.

Nonwovens used for respiratory masks have to meet the same high-quality requirements as the masks – to ensure the protection of the mask wearer.

Members of the VDMA Textile Machinery Association have reacted to the new market requirements in a very short time and developed new technologies for knitted, warp knitted as well as woven mouth and nose masks that can be produced without the need for sewing. For surgical masks, FFP2 respirators and social distancing masks, a wide variety of other materials and combinations of materials are used (nonwovens, woven fabrics, knitted or warp knitted fabrics and laminates thereof). Elastic bands are required to wear the masks and several association members provide technologies for their production.

Materials for masks can be treated with textile chemicals to make them antiviral and antibacterial. For this purpose, the VDMA member companies offer application systems which apply the corresponding chemicals to fabric webs. As already mentioned, quality assurance is extremely important for medical products. For this purpose, member companies of the VDMA offer software systems with which each mask can be traced through the entire production process.

VDMA members also offer solutions for the assembly of respirator masks, some of which were developed at short notice. These solutions enable respirators to be produced that meet the relevant standards and the highest quality requirements of customers and market surveillance. This applies to systems for the production of surgical masks and FFP respirators. At the end of the production chain, machines are used to pack masks in single or multiple packs.

In pandemic times, the demand for protective gowns (so-called surgical gowns) also increases. The same applies to disinfecting wipes. For these textile products, too, VDMA members manufacture tailor-made machines for production through to packaging. The quality of the products is ensured by means of measurement and control technology.

In the wake of the corona crisis, VDMA Textile Machinery has launched a new series of web events called "Textile Machinery Webtalk". Here, experts from up to four VDMA member companies present their innovative technologies on a specific topic in a maximum of 90 minutes and are available to answer questions from participants. The presentations are held in English. Participation in the web events is free of charge.
Topics of the first two webtalks were:
"Technologies for the production of melt-blown nonwovens for respiratory protection masks (FFP masks and surgical masks)."
"Technologies for the production of respiratory protection masks (FFP masks and surgical masks)."

The format is well received. Around 180 people from more than 30 countries took part in the first two webtalks. With this format, the VDMA reaches both textile and nonwovens manufacturers who already manufacture these products and companies that want to invest in new business areas.

The next webtalk will take place on 23 July 2020 from 14.00 to 16.00 (CEST) on the current topic "Technology solutions to produce fully-fashioned community face masks." Experts from KARL MAYER, STOLL by KARL MAYER and Jakob Müller will be presenting their technologies for producing everyday textile masks to an international expert audience. Interested parties can register here.

Wilhelm-Lorch-Stiftung awards ITA graduate and a project at ITA with sponsorship prizes

Carbon dioxide-based fibre for climate protection and interdisciplinary training with novel Smart Textiles test rig

The Wilhelm-Lorch-Stiftung, based in Frankfurt am Main, Germany, honours a project of the Institut für Textiltechnik of RWTH Aachen University, short ITA, and awards a sponsorship prize to the ITA graduate Ricarda Wissel on 25 June 2020. She is awarded for her outstanding bachelor thesis " Implementation of elastic yarns made from carbon dioxide based thermoplastic polyurethane in socks " with funding for a subject-specific continuation of her education. The ITA receives the project sponsorship prize for the project "Smart Textiles - an interdisciplinary training course to promote young scientists in future technologies", which was submitted to the Wilhelm-Lorch-Stiftung by ITA´s PhD candidate Simon Kammler.

She is awarded for her outstanding bachelor thesis " Implementation of elastic yarns made from carbon dioxide based thermoplastic polyurethane in socks " with funding for a subject-specific continuation of her education.

Carbon dioxide-based fibre from industrial waste contributes to climate protection

ITA scientist Dr.-Ing. Pavan Manvi has developed a melt spinning process at ITA for the production of elastic yarn from thermoplastic polyurethane, in which carbon dioxide is used as one of the raw materials. In her bachelor thesis, Ricarda Wissel successfully developed a process chain for the CO2-based yarn in a textile end product for the first time. In cooperation with the company FALKE and Dr Manvi, who supervised Ms. Wissel's work, the yarn was used to produce a sock (see figure "FALKE sock with carbon dioxide filaments").

By reusing carbon dioxide from industrial waste as a raw material for textile and clothing products, the carbon dioxide balance can be improved and thus contributes directly to climate protection. The sponsorship prize of the Wilhelm-Lorch-Stiftung is endowed with 6,000 € for the specialist further training of Ms. Wissel.

Interdisciplinary training with development of a new type of measuring stand for the future-oriented research field "Smart Textiles

The development of textiles with additional digital functions, so-called "Smart Textiles", is considered a future-oriented field of research. In his project submission, ITA´s doctoral candidate Simon Kammler presented a concept for a lecture series on Smart Textiles at ITA and develops a new type of measuring stand for measuring the capacity and conductivity of fibres. The project is funded by the Wilhelm-Lorch-Stiftung with a prize money of 10,000 Euro.

Smart Textiles enable the textile to interact with the environment and the human user. Today they are therefore in demand in many areas of everyday life such as sport, health, living, life and mobility and offer completely new practical solutions. In combination with digital networked services, Smart Textiles promise support and innovation in almost all situations of daily life.

With the conception of a new lecture series, Mr. Simon Kammler is supporting ITA in its goal of providing the best possible training for young scientists. The focus is on imparting far-reaching interdisciplinary skills in order to master the challenges of current fields of research.

Background:

The Wilhelm-Lorch-Stiftung supports particularly talented young people from all areas of the textile industry. Its purpose is the promotion of subject-specific education and further education as well as the promotion of projects at universities, academic schools and vocational schools, which are characterised by the sustainable communication of innovative learning content in science and research. In total, thirteen sponsorship prizes were awarded in 2020. Due to the Corona crisis, the forum of TextilWirtschaft, which is normally the venue for the awards ceremony, unfortunately had to be cancelled in 2020.
