GENERAL OBJECTIVE:
The enhancement of the dyeing of cellulose and animal fibers with plant infusion of flowers, berries and roots, by enzymatic pre-treatment (hydrolase) aimed to obtain a wider set of colours and nuances, with good colour fastness and improved uniformity of the dyes
NOVELTY ELEMENTS:

  • the development of an effective natural dyeing process of natural fibers, based on enzymes as auxiliary for pre-treatment or for natural dyeing with or without natural mordanting, to improve the uptake and the fixation of the natural dyes
  • the development of an ultrasonic-enzymatic pre-treatment of technical fibers leading to high quality of cottonised flax/hemp fibers with low average consumption of enzymes and significantly reduced time

EXPECTED EXPLOITABLE RESULTS:

  • development of an innovative natural dyeing process assisted by enzymes, suitable to create a completely natural textile products
  • environmentally friendly process with lower energy consumption, leading to substantial improvements of the environmental footprint, higher safety and protection of the people involved in the production of dyes
  • consolidating the knowledge regarding UV-protection properties of the natural dyes and antibacterial activity
  • reintroduction of ancient cultivations of herbs and plants representing an important cultural heritage of skills of the past, bringing a potential advantage for the development of territories

ACTIVITIES PERFORMED BY INCDTP IN 2012:

  • Selection of enzymes and study of applicative conditions for bast fibers with the aim of removing noncellulosic compounds and to increase fibers  hidrophilicity, in relation to herbal natural dyeing
  • Laboratory experiments with selected enzymatic systems on hemp and flax
  • Investigation of enzymatic catalytic action and of the enzymatic processes impact on bast fibers characteristics

TECHNOLOGIC STUDIES (1):
Technologic study: Study of the enzymatic processes applied on bast technical fibers using selected enzymes; investigation of the enzymatic catalytic action on bast fibers characteristics
