Suntech non-woven fabrics help human health


During the covid-19 pandemic,People use a lot of medical supplies such as masks and protective clothing,Masks are mainly composed of non-woven fabrics, and non-woven fabrics are the key to isolate the virus.suntech helps human health.

In 2020, the covid-19 pandemic is sweeping the world. Although countries are vigorously developing vaccines, the cost of vaccine research and development is high and the cycle is long. Due to virus mutations, the effectiveness of vaccines remains to be discussed, and it will take a long time for the popularization of vaccines. Masks are the oldest and most effective method of epidemic prevention, blocking the spread of the virus through virus isolation.


Masks are mainly composed of non-woven fabrics, and non-woven fabrics are the key to isolate the virus.The nonwovens and related industries play a major role in producing materials essential to reduce the spread of COVID-19.  From disinfecting wipes to face mask and personal protective materials.Click to share to LinkedIn


What are nonwovens?

Nonwovens are innovative, high-tech, engineered fabrics made from fibres.  They are used in a wide range of consumer and industrial products either in combination with other materials or alone.


Nonwovens are designed for their specific application, ranging from thin, light weight nonwovens to strong and durable nonwovens, be it consumer or industrial applications. The combination of their specific characteristics through the raw materials selection, the formation and bonding methods used or the applied finishing treatments, such as printing, embossing, laminating etc. allow to deliver high-performance products.

ISO and CEN definition of nonwovens

Nonwovens are defined by ISO standard 9092 and CEN EN 29092. These two documents, identical in their content, are the internationally acknowledged definition of Nonwovens. As industry, trade and technology have evolved since their first publication in 1988, these standards are regularly being updated by experts to better reflect the present understanding of Nonwovens. The following text, prepared by the leading nonwovens trade associations, reflects the current definition of nonwovens and the related terminology.


A nonwoven is an engineered fibrous assembly, primarily planar, which has been given a designed level of structural integrity by physical and/or chemical means, excluding weaving, knitting or paper making.Click to share to Facebook


Supplement A: Relative Terminology Defined

1.Fibrous Assembly

A predetermined amount and arrangement of natural or manufactured fibrous material such as, but not limited to fibres, continuous filaments, or chopped yarns of any length or cross-section. It can be a two- or three-dimensional alignment of fibrous materials made by a web forming process.



An application of science to design, plan and manufacture products to utility specifications.


3.Structural Integrity

A measurable level of added tensile strength.


4.Physical and/or Chemical Means

Bonding technologies that result in frictional forces between fibres (through entanglement) or adhesive forces between fibres (with or without the use of binders).



5.Paper making

Paper making, in this context, is regarded as the process of producing a thin material by pressing together, short, refined cellulose fibres formed on a screen from a water suspension of these fibres, and drying them, with hydrogen bonding as the predominant mechanism holding the web together.


The refined fibres plus the self-bonding that occurs between cellulose fibres during drying distinguish paper from wet-laid nonwovens.


When re-wet, the hydrogen bonds between fibres are broken, and paper typically loses almost all of its strength.


6.Wet laid process that is not paper making

In a wet laid process where cellulose or other fibres are engineered to a level of structural integrity primarily by physical and/or chemical means other than hydrogen bonding, the resulting assembly is considered a nonwoven.


Note: most materials made through a papermaking process are classified as paper products per ISO 4046-3, but some might be classified as nonwovens, particularly where clear differentiation between the primary means of bonding is not possible.try Suntech ST-AMB Meltblown machine


Supplement B: Distinction between nonwovens and related materials


Films cast, blown or extruded from polymers, which then through physical or chemical means are made into fibrous assemblies, can be considered nonwovens if the L/D ratio of the fibrous elements is over 30.



These materials are classified as nonwovens. They are primarily fibrous and engineered to a given level of integrity by physical means for specific applications. The warp or circular knit stitching is the additional bonding technology.



Waddings are high-loft assemblies, primarily fibrous, engineered to a given level of integrity by physical means for specific applications. Waddings are not woven or knitted and can be considered a high-loft nonwoven when bonded throughout the assembly.


Nonwoven composites and nonwovens in multi-component structures

Generally, nonwoven composites (hybrid nonwovens) and nonwovens that are combined with other discrete materials are to be considered as nonwovens.

Promoting sustainability of nonwoven


We understand sustainability as affirmative action to minimise negative impact on the environment and to create positive environmental, social and/or economic developments in the activities of the nonwovens industry. This is to be created in close dialogue and partnership with all of our stakeholders.


The Suntech Sustainability Vision


Suntech developed a Sustainability Vision 2030, giving clear insight into the priority topics on sustainability for our industry.


The vision combines the most prominent topics of the materiality matrix with key United Nations' Sustainable Development Goals (SDG's) for the industry. The four key areas are:  Sustainable supply chain, Eco-efficient, Building trust and Responsible end of life. Each area is defined by a clear ambition.


The vision aligns the industriespriorities and allows the industry to collectively head in the same direction. It should be interpreted as a guideline rather than a rule to help our members identify their priorities and further develop their own sustainability strategy. suntechs role is to facilitate interaction and help the industry progress towards their sustainability goals in line with the United Nation's SDGs.

Product stewardship

suntechs mission for the last 50 years has been to support the industry, especially in areas of performance and safety requirements


Product stewardship encompasses the environmental, health and safety dimensions of a product and everyone, involved in its life cycle. The nonwovens industriesapproach for a sound product stewardship materialises through different approaches such as the development of technical standards, the investment in better and innovative technologies, the adoption of regulations where necessary, the continuous efforts towards more sustainability and the dialogue with consumers and stakeholders.


suntech supports its membersefforts activities in the dialogue with stakeholders, in the development of position papers, test method and regulatory solutions. This approach towards product stewardship is a strong part of the global message our team is spreading in conferences and symposiums across the world.


With 50 years of technical precipitation and design experience, suntech has developed and produced intelligent non-woven fabric machines, including spunbonded non-woven fabric machines, spunmelt non-woven fabric machines, melt blown machines, etc., to help human health and care for everyone's lives.
