Inspecting non-wovens

The ASIX is a complete turnkey machine vision solution designed for 100% inspection of non-woven substrates. The ASIX inspection solution  will detect defects and track them through the manufacturing process.  lets look at the  four main types of non-woven products: Spunbound/Spunlace, Airlaid, Drylaid and Wetlaid. 

  1. Spunbound/Spunlace.
  2. Airlaid.
  3. Drylaid.
  4. Wetlaid.

Spunbound/Spunlace

Spunbound fabrics are produced by depositing extruded, spun filaments onto a collection belt in a uniform random manner followed by bonding the fibres. The fibres are separated during the web laying process by air jets or electrostatic charges. Spunbound products are employed in carpet backing, geotextiles, and disposable medical/hygiene products, automotive products, civil engineering and packaging products.

Airlaid

Airlaid fabrics is mainly composed of woodpulp and has a nature of absorbing well. It can be mixed with a definite proportion of SAP to improve its capabilities of absorbing wet. Airlaid non-woven products are employed in a number of different products across a wide range of industry’s including; the interlining of clothes, medical and hygiene products, embroidery material and filter material.

 Drylaid

Dry laid webs are mainly produced using staple fibres natural or man-made. Drylaid non-woven products are employed by many products ranging from cosmetic wipes and baby diapers to beverage filtration products.

 Wetlaid

Wetlaid non-woven are non-wovens made by a modified papermaking process. That is, the fibres to be used are suspended in water. Wetlaid is used for a wide ranging amount of industries and products. Some of the most common products that use wet laying non-woven technology include; Tea bag paper, Face cloths, Shingling and Synthetic fibre paper.
