More than 50% of non-wovens produced annually are converted into single-use products such as diapers, wipes, and other hygiene or medical products. On disposal, several million tons of these products find their way into landfills. Moreover, most single-use products contain petroleum-based fibres made from PP, PET, bi-component polymers etc. Discarded carelessly, these non-wovens containing synthetic fibres can disintegrate into micro-fibers or micro plastics that do not biodegrade for decades and infiltrate soil, water, air and living things.

India is ranked 94 out of 100 in single-use plastic waste generation. With domestic production of 11.8 Million Metric Tonnes (MMT) and import of 2.9 MMT of plastic annually, India’s net generation of single-use plastic waste is 5.6 MMT per year.

The Indian Government has proactively banned the use of ‘single-use plastic’ from 1July 2022. A notification issued by the Ministry for Environment, Forest and Climate Change has prohibited manufacture, import, stocking, distribution, sale and use of various types of single-use plastic, including polystyrene and expanded polystyrene commodities.

The ban makes it imperative for manufacturers to explore other, sustainable raw materials to manufacture products, thereby helping to reduce the detrimental effects on the environment.

Enter Carded/Pulp (CP) nonwovens solutions by Truetzschler

Carded/Pulp (CP) is an eco-friendly alternative to technologies that use non-biodegradable materials. CP consists of wet-laying technology combined with a separate carding process resulting in two-layer, composite carded/pulp webs which can be used to produce excellent body and baby wipes. The wet laid layer, which is produced from 100% pulp,is cost effective,voluminous, and quickly absorbs liquids. The lyocell or viscose fibres carded layer lends sufficient strength to the wipe to maintain structural integrity while ensurings oftness.

Carded/pulp (CP lines for pulp-based nonwovens)

NBSK (Northern Bleached Softwood Kraft) pulp is a new, cost-effective, sustainable material suitable forthe production of carded pulp spunlaced nonwovens.A blend of NBSK pulp and short viscose or lyocell fibres can be used to generate a web, which can be laid down on a belt.

The WLS (Wet-laid Spunlace) process is the technology of choice for producing Moist Toilet Tissue (MTT). Voith’s HydroFormer has been specifically optimised for the formation of wet-laid non-wovens. In the wet-laid process,Voith’s HydroFormer prepares the fibres and forms the web. As lurry of fibres and water is passed over a wire mesh on which a homogeneous fibre mat forms. The downstream hydro-entanglement (spunlacing) process is accomplished using Truetzschler Nonwovens’ AquaJet system which produces bonded nonwovens that can also be textured or perforated, if required. Because AquaJet bonds the nonwovens through the momentum of the water jets, there is no need for binding agents or bi-component fibres.The bonded web is then dried and wound.

With more than 70 HydroFormer and 100 AquaJet successful installations, both the HydroFormer and AquaJet are proven products.

Additionally, Truetzschler’s TWF-NCT high-speed card can be integrated into the line, in front of the AquaJet. This allows production of CP nonwovens. Combining the wet-laying with a separate carding process results in two-layer, composite carded/pulp webs. These composite materials, each consisting of one layer of wet-laid and carded webs enables the production of a wide variety of high-quality products – from carded non-wovens to wet-laid/spunlaced WLS materials to multi-layer CP products.

Features:

  • Raw material: paper-grade wood pulp, re-generated cellulose fibres (viscose, lyocell)
  • Flexible lines: for CP and WLS nonwovens
  • Web weights: 50 gsm; pulp layer more than 25 gsm
  • Line speed: up to 300 m/min
  • End products: baby and body wipes; flushable wipes/MTT without card
