A biological treatment technique for wool textile

Enzymes are a sustainable alternative to the harsh toxic chemicals in the textile industry. As enzymes operate in moderate conditions of temperature and pH, energy consumption is reduced, thereby reducing greenhouse gas emissions. Both water consumption and waste generation during textile manufacturing are also minimized by enzyme use. As the enzymes are very specific in their actions, minimum by-products are generated. The risks to humans, wildlife, and the environment are minimized. Enzymes can be utilized in several steps of textile processing namely desizing, scouring, bleaching, and biopolishing of cotton, degumming of silk, bleaching and shrinkproofing of wool, biostoning (of denim), and for treatment of textile effluents.

Surfaces of cotton, polyester (PES) and polyamide (PA) fabrics have been modified by the sol-gel process in order to achieve silica based hybrid coatings onto the fibers for enhancing their water repellency, thermal stability and mechanical properties. The effects of synthesis parameters such as the concentration of the alkoxysilane used as main precursor, the chloropropyltriethoxysilane (CPTS), and the impregnation time of the fabrics in the solution (sol) prepared have been thoroughly investigated, aiming at the optimization of the targeted properties. Scanning electron microscopy images of the sol-gel treated fabrics exhibit significant differences from the untreated ones. The amount of silicon deposited onto the fabrics was determined by inductively coupled plasma atomic emission spectroscopy. The droplet shapes analysis confirmed that the water repellency of the fabric was dramatically improved after sol-gel treatment. The breaking strengths of the PES and PA fabrics coated with CPTS sols increase with higher sol concentration. Thermogravimetry analyses have been used to assess the thermal stability of treated fabrics. Finally, the influence of accelerated artificial photoageing on water repellency properties was investigated.
