Breakthroughs in textile dyeing machine design

The following article highlights some of the new developments in textile dyeing machines designed to reduce energy consumption and reduce waste flow to the lowest level in textile processing.

The process of dyeing is exhausted

Then textile dyeing machine manufacturer has combined the advantages of long tube machine design with aerodynamic fabric transportation principle with newer developments – THEN-AIRFLOWLOTUS – is the first long tube machine on world – works on the original aerodynamic principle. The goal of development is to create a system especially suitable for the wet processing of knitted and woven fabrics of cellulose and sensitive, easily creased, synthetic fibers, with a high percentage of elastane fibers – used. in “lingerie,” sports, leisure wear and swimwear.

Resource benefits focus on low 1: 2 to 1: 5 ratios, accompanied by reduced water demand, volume and effluent loading due to reduced salt consumption when reactive dyeing is reduced, and energy requirements reduced. amount.

The THEN-AIRFLOW SYNERGY is based on an improved circular steamer design that allows high temperature water discharge to a closed water collection tank to recover heat while the fabric is running, thus increasing productivity and preventing Preventing the re-adhesion of impurities and oligomes when dyeing polyester fabrics.

A new machining process for polyester / cotton blends has been developed with DySatr to show an efficiency reduction of 8% for chemicals, 35% water, 6% steam and 50% more electricity than for machines and stock processes. infused.

FONG TECHNICAL has improved their JUMBOFLOW

with Advanced Intelligent Rising (AIR) with the conductivity measurement option to detect when the concentration of the electrolyte decreases after the reactive dyeing process to the concentration at which the rinsing process is switched. soap washing process, thus optimizing water consumption.

THIES has further developed their ecoMaster machine incorporating the Multi Contact Dyeing dyeing process, which reduces dyeing time and low ratio from 1: 3 for synthetic to 1: 4.5 for cotton, and automatically controls the process. process by using the RINSEtronic software to further reduce machining time and water consumption.

The development of gas / hydraulic exhaust dyeing machines under the collaborative project between THIES and DyStar led to high-tech Luft-roto plus – demonstrating market leading process flexibility.

A fast dyeing process for dyeing black reactive dyes specifically suited for vertical dyeing has been developed with DyStar – offering up to 30% higher productivity with up to 60% reduction in water consumption. and 40% energy.

The process of dyeing, pressing and coiling cold coiling

For vertical knitting fabric processing, special attention is usually paid to reactive dyeing by cold roll coiling due to less water consumption and reduced waste load with cost reduction being said to be from 15 to 30%. As a result, fabrics with stitches look cleaner because they do not fray the surface and produce the same mass / square meter as the full dyeing process, and an increase in stitch density should be considered at the weaving stage. if you intend to use cold-pressed soaked rolls.

Developments in machine design are almost exclusively for open-width machining processes that use sophisticated automatic centering and anti-framing mechanisms but also include dispensers.

amount, low-capacity infusion troughs and configurations that allow the dye to be placed on the fabric in the clamping path of the shaft or in the low-capacity chute. On modern shafts the pressure can be adjusted over the entire shaft length to allow uniform infusion to eliminate the border-between-edge color variation of the fabric.

Integrated heating and cooling systems have also been developed to ensure a constant temperature in the feed trough no matter the day and season, and thus improve the reliability of the dyeing process and the stability. determination of billions / incubation time.

For deep colors DyStar has developed the Remazol Ultra RGB reactive dyes with high color intensity and binding value, which allows deep dyeing with reduced amount of soluble dyes and reduction of hydrolysed dyes that need to be washed. therefore, reducing the color in the waste stream. In addition to the concentrated silicate-free alkali, Sera Fix C-SF has been added to simplify the processing and dissolution process, and prevent deposits on the platen and cloth shaft, reducing the effect of electrolytes. causing an increase in the self-staining of hydrolysed dyes, and facilitating the washing process.

For colors like beige, khaki, and gray on woven fabrics with the highest color fastness performance requirements, DyStar has developed a new dye combination that reduces the discoloration between the right side and left to the lowest in both tone and color density. Preferred combinations based on Levafix Amber CA, Levafix Fast Red CA and Levafix Blue CA offer high color fastness without chromatic aberration.

As part of the DyStar ColorXPT software program, Optidye CR calculates the optimum conditions for solution stability and color fastening time for Remazol and Levafix dyes with regard to the material.
