DyStar: Breakthrough in bulk production of Indigo spray dyeing

DyStar and RotaSpray successfully developed their indigo spray dyeing procedure for production on a bulk level which allows denim producers to significantly reduce their environmental impact.

The solution was first introduced at ITMA Milan in 2015. Since then, DyStar and RotaSpray have been working together to develop it further and make it available for bulk production in important Denim markets like Turkey, India and Pakistan. With the recent breakthrough, they are now announcing a salt-less dyeing solution for the denim industry. This new technology is awarded important ECO certificates and offers high flexibility for dyeing small lot sizes, reduced water usage and effluent discharge lower impact on yarn in the dyeing process and simplified recipe changes.

The new Spray dyeing technology combines DyStar Indigo Vat 40% Solution, Sera® Con C-RDA (a unique organic reducing agent) and the effective optimization of spraying parameters of the EPO patented RotoDyer® and the RotoCoater® spraying technology. Although rotary atomizers have been established for several decades in the textile industry they were mainly used for rewetting textiles with moisture. But recent cost pressure and a global demand for more sustainable solutions were motivators for the R&D of the industry and led to the recent technology leap.

On sheet dyeing ranges (slasher), with process and layout modifications, coatings including DyStar Indigo Coat, Cassulfon®, Remazol®/Levafix® and Imperon® dyes can be applied by spray dyeing as well. The spray application of fixing agents and oxidation chemicals can be integrated into sheet dyeing (slasher) as well as rope dyeing machines.

Crown Health Care Laundry Completes System-Wide Hygienically Clean Certification

Earlier this year, the Pensacola-based operation achieved Hygienically Clean Healthcare certification in its Quitman, Ga. and Columbia, Miss. facilities.
In addition, the Crown Health Care Laundry facilities passed three rounds of outcome-based microbial testing, indicating that their processes are producing Hygienically Clean Healthcare linens and garments and zero presence of harmful bacteria. To maintain their certification, laundry plants must pass quarterly testing including yeast and mold detection to ensure that as laundry conditions change, such as water quality, textile fabric composition and wash chemistry, laundered product quality is consistently maintained.
This process eliminates subjectivity by focusing on outcomes and results that verify textiles cleaned in these facilities meet appropriate hygienically clean standards and BMPs for hospitals, surgery centers, medical offices, nursing homes and other medical facilities.

Hygienically Clean Healthcare certification acknowledges laundries’ effectiveness in protecting healthcare operations through testing and inspections that scrutinize quality control procedures in linen and uniform service operations. The Hygienically Clean standard provides for two inspections every three years. OSHA compliance is closely examined, particularly toxic and hazardous substance handling rules governing textiles containing blood and other potentially infectious materials.
Certified laundries use processes, chemicals and BMPs acknowledged by the federal Centers for Disease Control and Prevention (CDC), Centers for Medicare and Medicaid Services, Association for the Advancement of Medical Instrumentation, American National Standards Institute and others. Introduced in 2012, Hygienically Clean Healthcare brought to North America the international cleanliness standards for healthcare linens and garments used worldwide by the Certification Association for Professional Textile Services and the European Committee for Standardization.
Objective experts in epidemiology, infection control, nursing and other healthcare professions work with TRSA launderers to ensure the certification continues to enforce the highest standards for producing clean healthcare textiles. With 100+ years as the textile services industry's leading business association, TRSA's expertise in laundry BMP development is unmatched.
