Water

Every creature on earth depends on water for life. Santex Rimar Group wants to preserve this most precious of all natural resources. Factors such as population growth and urbanization place increasing demands on the planet’s limited supplies. But Santex Rimar’s impact is positive: our machinery actually saves water.

That achievement gives the Group’s development engineers a big task to live up to. They need to produce machines which give the required textile results, but use as little water use as possible. Innovations aim at perfection in the quest to save even one more liter of water.

Achievements in water-saving are reported in weaving, finishing and technical textiles as well as in the special field of water treatment.

WEAVING - SMIT

2SAVE

2SAVE controls weft thread tension outside the fabric edge and cuts false selvedges at both sides of the fabric, saving fabric waste during production. A significant amount of weft yarn can be saved.

Eliminating selvedge waste leads to a notable reduction in raw material waste, with tangible benefits in terms of water saving at the very beginning of the value chain of fabric making – for any cotton fabric, including denim.

Facts & Figures:

  • 2SAVE is the sustainable option for 2FAST, the free-flight rapier loom
  • 2SAVE offers control of weft thread tension outside the fabric edges to avoid selvedge waste
  • Weft saving 55 mm (25 mm + 30 mm) at each pick
  • Weft yarn recycling 80 mm (25mm + 55mm) at each pick
  • False selvedges warp yarn full saved
  • 720 kg cotton saved per year*
  • 7,920,000 litres of water saved per year*

* Figures based on example using weft of Ne10s and weft density 25 pick/cm. Machines running 24 h on 30 days during 11.5 months at 680rpm with 92% efficiency resulting in 55mm weft saving.

FINISHING - SPEROTTO RIMAR

COMPAS

COMPAS features a new and unique compacting system which exploits the use of a special belt with specific elasticity values. This elasticity is exploited in order to enhance the fabric compacting.

COMPAS also features unique indirect rubber belt cooling technology, making it unnecessary to spray water on the compacting belt surface. This results in an unpolluted water recycling system, since there’s no water absorption by the processed fabric.

Facts & Figures:

  • Compacting process without polluting water
  • Water closed loop recycling system

NOVA

NOVA is a dry to dry continuous water-free scouring machine. It’s the ideal solution to get rid of oils and silicones contained in fabrics at loom state. Remaining oils inside synthetic fabrics after the process are reduced to 0.2% or less, from starting values of 2.5 to 3%.

NOVA does not use water during the scouring operations. Water is used for cooling purposes only and can be recycled totally pure in a closed loop circuit by sending it back to the machine, or used for other purposes (e. g. dyeing) pre-heated at 45°C. Huge amounts of water are saved this way.

Facts & Figures:

  • Negligible environmental impact
  • Huge water saving

WATER TREATMENT – DRYWA

DRYWA

DRYWA stands for an innovative integrated system for drying sewage sludge. DRYWA technology allows sustainable sludge management – 100% green and eco-friendly – with the lowest energy consumption, as it’s the only low-temperature belt dryer equipped with a CO2 heat pump. Sewage sludge and sludge from ETP (particularly from dyeing companies) are perfectly treated by DRYWA without odours and air emissions, even without filters.

Facts & Figures:

  • Mechanical dehydration process
  • Dehumidification process with low environmental impact (minimum values for ODP and GWP)
  • Using a heat pump model that ensures a closed circuit and guarantees no emissions of any kind.

COATING – CAVITEC

CAVIMELT PRO

CAVIMELT PRO is a two-in-one coating and laminating machine based on hotmelt technology – providing high-quality results without a single drop of water – and also without solvent.

Hotmelt adhesives commonly used in textiles are one-component solvent-free thermoplastic polymers (non-reactive) or thermoset pre-polymers (reactive), which are heated to the melting point prior to application. Hotmelt is applied onto a substrate material such as wovens, knits, nonwovens, foams, membranes, films, nets, silicon paper, etc. in hot plasticized state for coating or bonding and gluing two layers of material together to build a composite material.

Facts & Figures:

  • Using environmentally friendly adhesives such as one-component solvent-free thermoplastic polymers or thermoset pre-polymers
  • No use of water or solvent
  • The new technology also saves significant amounts of energy because there is no drying process necessary
