How to Choose the Right Fibre for My Nonwovens: Properties Expectation

Manufacturers of nonwovens have a wide range of fibre options. For some applications, natural fibres such as cotton are a good choice, but for other applications, synthetic fibres such as polyester may offer better properties.
What properties do you want in the final product? You need to pick the fibre material according to your expectations.

Absorbency: cotton

For excellent absorption and release with a high degree of comfort and softness, cotton fibres are a good choice. Natural fibres, rayon filaments and rayon blends are derived from wood pulp and are highly absorbent, soft and comfortable. Non-woven cotton and non-woven rayon are an excellent choice for hygiene products such as feminine products, nappies and personal wipes.

Temperature resistance: chemical bonding

When your nonwoven products need to be heat-resistant, quality fibres to choose from include: cotton, rayon, polyester and blends. Chemical bonding is also an effective way of developing high temperature resistant nonwovens. The chemical bonding process involves the application of chemical binders to join polyester and rayon fibres, thereby creating beneficial properties for the nonwoven, including heat resistance.

High strength: synthetic fibres

When your product needs to be strong and durable, synthetic fibres provide high tensile strength. High-strength synthetic fibres can be blended with weaker fibres to create strong, bi-component fibre nonwovens. Polyester filaments or polyester blends provide excellent strength because of the high density of polyester nonwovens.

Sustainability: natural fibres

If sustainability is your top priority as a manufacturer, then natural fibres are a responsible choice. Although natural fibres are considered more expensive, they can be manufactured in such a way that they are cost-competitive with synthetic fibre products. It is important to choose a supplier who is experienced in developing environmentally friendly nonwovens.

Resistant to stretching: polyester fibres

Polyester fibres are a good choice for nonwovens that need to retain their shape without shrinking, stretching or creasing. Bicomponent fibres can also be used to create properties such as resistance to washing or dry cleaning, resistance to ageing and excellent flexibility and handling.
