Process Engineering: Cool Denim Jeans with Rough Wild West Look

With the right application and engineering know-how you can create in several process steps cool denim garments, jeans and jackets in a bold, robust, rough Wild West Look. Hereafter, we describe the applied process methods with special enzymes and textile auxiliaries for the production of these particular indigo-dyed jeans. Each single garment obtains an individual appearance through the special finishing process.

Techniques for Jeans with Individual, Robust Look and Strong Contrasts

In addition to their individual look and the strong color contrast these cool jeans have a unique soft and greasy handle. Furthermore, thanks to the elaborate recipes and finishing techniques, they are very robust and resistant to environmental influences such as yellowing caused by ozone (O3) or nitrogen oxide (NOx) as well as fading of the indigo dyestuff.

Our Process Recommendation for Garment Finishing

The particular effects on these jeans in a bold, rough Wild West Look can be created by means of the following enzymatic and textile-chemical process steps and garment finishing processes:

  • Enzymatic desizing
  • Super stone wash with cellulases
  • Permanganate-free, ecological bleaching
  • Greasy luster effect by spray coating
  • Softening finishing to avoid ozone fading and yellowing

Pretreatment of the Jeans Garments and Super Stone Wash

After a pretreatment of the indigo warp-dyed goods – usually a desizing process with amylases – an enzymatic super stone wash with special cellulase enzymes is carried out. Therefore, we suggest the use of the two following textile auxiliaries:

PERIZYM SC 500

PERIZYM SC 500 is a cellulase enzyme preparation for the stone wash of denim articles at low temperatures.

PERLAVIN JAB NEW

PERLAVIN JAB NEW is a special product with anti-backstaining properties for garment washing.

Indigo Bleaching without Potassium Permanganate

After stone washing the garments are bleached with a special potassium permanganate-free indigo bleaching process. We have developed this environmentally friendly PERISTAL BLI ECO method, which is carried out with the following two products:

PERISTAL BLI 85 N ECO

PERISTAL BLI 85 N ECO is an ecological oxidizing agent for spray bleaching of indigo-dyed articles.

PERISTAL BLI 15 ECO

PERISTAL BLI 15 ECO is an inorganic compound with bleaching properties for oxidative bleaching.

Spray Coating for Greasy Luster Effect

In order to create this special greasy luster effect on jeans garments the pieces are first treated by spray coating with PERIPRET LUSTER 2 in combination with PERICOLOR P pigments. After drying and curing of the glossy coating the greasy effect is generated on a tumble dryer, where the goods are treated with silicone balls.

PERIPRET LUSTER 2

PERIPRET LUSTER 2 is a special sprayable polymer compound for the production of glossy effects on garments.

Finishing to Avoid Ozone Fading and Yellowing

In the next process step the trousers are finished on a drum washing machine with PERISOFT LOF/R. This is a silicone-free softener for indigo-dyed garments. PERISOFT LOF/R offers a pleasant smooth and very soft handle. Furthermore, the softening minimizes the risk of ozone fading and yellowing. Finished goods are better protected against color changes and environmental influences caused by ozone or nitrogen oxides.

PERISOFT LOF/R

PERISOFT LOF/R is a softener for indigo-dyed denim articles to minimize yellowing and fading caused by ozone or nitrogen oxides.
