In the contemporary textile industry, the judicious selection of chemical auxiliaries is a determining factor for operational efficiency, the superior quality of the final product, and the minimization of environmental impact. With more than four decades of experience and headquarters in Braga, LEDECHEM has established itself as a national reference in the production and commercialization of chemical products for the textile industry, offering a diversified portfolio of certified solutions designed to meet the specific challenges of each fiber type.
What are Textile Auxiliaries?
Textile auxiliaries are essential chemical products in various stages of textile processing, from pre-treatment and dyeing to finishing. Their functions are specialized and include, among others:
- Pre-treatment: Wetting, desizing, peroxide stabilization, and removal of impurities.
- Dyeing: Dispersion, leveling, lubrication, dyestuff protection, and water conditioners.
- Different types of finishing: dimensional stability, repellency, antiviral effects, and odor control.
Selection by Fiber Type: LEDECHEM Solutions
An auxiliary's performance is directly linked to its compatibility with the fiber being processed. Here is a technical guide based on the LEDECHEM portfolio:
1. Cellulosic Fibers (Cotton, Viscose, Linen)
- Pre-treatment and Bleaching:
- Ledestab FE: Organic hydrogen peroxide stabilizer for bleaching, with heavy metal sequestering properties.
- Ledequest DPS: Iron and calcium sequestering agent, ideal for correcting water hardness and protecting bleaching and dyeing baths.
- Dyeing Auxiliaries
- Ledegen VRD: Leveling and solubilizing agent for reactive, direct, vat, and sulfur dyes.
- Ledeslip LG: Anti-crease and lubricating agent, ensuring uniform processing and preventing fiber damage.
- Finishing
- Fatty acids, Micros and Macros for universal use such as Ledesoft Cat, Ledemin A.2, Ledesoft Pash, Ledesoft PEC, Ledesoft LC 30, Hidromacro, etc.
2. Polyester and Synthetic Fibers (PES, PA, EL)
- Dyeing Auxiliaries
- Dispersante AC Liq: High-efficiency anionic dispersing agent for disperse dyes, ensuring uniform color and preventing agglomeration.
- Ledegal JLD: Leveling and dispersing agent for high-temperature polyester dyeing, ensuring exceptional leveling and color reproduction.
- Ledecarrier Eco: Diffusion accelerator for low-temperature dyeing, promoting energy efficiency.
- Ledegen PA: Leveling and migrating agent for polyamide dyeing with acid and pre-metallized dyes.
- Finishing
- Ledeguard Eco: C6 fluorocarbon emulsion, providing water and oil repellency.
3. Dyeing and Finishing of Garments and Denim
For the complex challenges of fiber blends and garment processing, LEDECHEM offers a wide range of solutions for dyeing with Ledewash, Direct, Reactive, and Sulfur dyes, as well as various types of fade-out finishes.
