WETLAID

Wetlaid non-woven are non-wovens made by a modified papermaking process. That is, the fibres to be used are suspended in water. A major objective of wet laid nonwoven manufacturing is to produce structures with textile-fabric characteristics, primarily flexibility and strength, at speeds approaching those associate with papermaking.

Specialized paper machines are used to separate the water from the fibres to form a uniform sheet of material, which is then bonded and dried. In the roll good industry 5 -10% of nonwovens are made by using the wet laid technology.

Wetlaid is used for a wide ranging amount of industries and products. Some of the most common products that use wetlaying non-woven technology include; Tea bag paper, Face cloths, Shingling and Synthetic fibre paper.

NON-WOVEN CHARACTERISTICS

The particular set of properties that a printed nonwoven fabric may have is dependent upon the combination of factors in its production. Each different ttype of non-woven will consist of different characteristics.

The range of characteristics include

  1. The appearance of non-woven fabrics may be paper like, felt like, or similar to that of woven fabrics.

  2. They may have a soft, resilient hand, or they may be hard, stiff or broadly with little pliability.

  3. They may be as thin as thin tissue paper or many times thicker.

  4. They may also be translucent or opaque.

  5. Their porosity may range from low tear and burst strength to very high tensile strength.

  6. They may be fabricated by gluing, heat bonding or sewing.

  7. The drapability of this type of fabrics varies from goof to none at all.

  8. Some fabrics have excellent launderability; others have none. Some may be dry-cleaned.

Non-woven fabric is a material defined as

Sheet or web structures bonded together by entangling fiber or filaments (and by perforating films) mechanically, thermally or chemically.

Non-woven polypropylene fabric is, similarly, a thermoplastic polymer – like polypropylene – but made to look non-woven. One of its major applications is non-woven bags for shopping. Nevertheless, the non-woven fabrics gain more and more popularity in the fashion industry.

With so many plastic bags ban policies sweeping the world in their attempt to reduce plastic pollution, non-woven bags (either for shopping or for fashion) are becoming the norm. But are non-woven bags as eco-friendly as advertised?

Why Are Non-Woven Bags Environmentally Sustainable?

As we all know, the true sustainability of a product or a fabric resides in its recyclability and reusability. Just like canvas shopping bags or jute bags, non-woven carriers are reusable for very long periods. Polypropylene is recyclable, and so are non-woven polypropylene tote bags for shopping or drawstring bags for sports or leisure.

After years of use, you can throw away a broken, non-woven polypropylene office bag uses PP nonwoven fabric, for instance. As long it is collected and appropriately sorted, you can rest assured it will enter the recycling process and give life to a new item.

Non-woven bags for shopping come with plenty of eco-friendly advantages that are not available to plastic bags or natural fibers, for instance:

You can wash them and disinfect them without worrying about their resilience; as long as you wash it in cold water, your washing machine will not take its toll on it;

You can spray your non-woven bags with disinfectants and anti-bacterial substances for enhanced safety, especially during these times of global health concerns;

Both woven and non-woven polypropylene comes from recycled materials (plastic), so it is easy to understand why non-woven shopping bags come with high levels of sustainability. They are products of recycling and make products of recycling in their turn.

Before we move on to the next reason why non-woven bags are the sustainable answer to plastic bags, we have to say that no plastic whatsoever is biodegradable or ecologically friendly.
