What is bio polish finish?
Bio-polishing is a finishing process in which a fabric is treated with an enzyme to impart properties such as anti-pilling, softness and smoothness. Further work was done on knitted fabrics where fuzz removal was added to the processing benefits .
What is bio Polish enzyme?
Removal of protruding fibres from garment surface using cellulase enzymes is called bio-polishing. These enzymes are proteins and capable of hydrolysing cellulose (cotton). In bio-polishing they act upon the short fibres protruding from fabric surface and make the fibres weak which are easily removed during washing.
What is Biopolishing in textile?
Biopolishing is a finishing process in textile that enhances fabric quality by decreasing the pilling tendency and fuzziness of (cellulose) knitted fabrics. This process removes protruding fibers & slubs from knitted fabrics, significantly reduces pilling, softens fabric hand and provides a smooth fabric appearance.
What enzymes are used in Biostoning?
Cellulases are the most successful enzymes used in the textile industry (Kuhad et al., 2011). Cellulases are used in the biostoning of denim garments (jeans) and biopolishing of cotton and other cellulosic fabrics (Bera et al., 2015).
Why Bio polishing is done?
Besides the “biostoning” process, cotton and other natural and manmade cellulosic fibers can be improved by an enzymatic treatment called “biopolishing.” The main advantage of this process is the prevention of pilling, which leads to an unattractive, knotty fabric appearance, thus affecting garment quality.
What is the purpose of stenter machine?
The purpose of the stenter machine is to bringing the length and width to pre-determine dimensions and also for heat setting and it is used for applying finishing chemicals and also shade variation is adjusted. The main function of the stenter is to stretch the fabric widthwise and to recover the uniform width.
What kind of finishing process includes Biopolishing and Biostoning?
Introduction: Textile finishing Cellulose biopolishing and biostoning are the two main applications of cellulases in textile finishing.
What is the function of cellulase enzyme?
Cellulase enzymes are used to break down the cellulose of plant cell walls into simple sugars that can be transformed (fermented) by microbes to fuels, primarily ethanol, as well as to chemicals, plastics, fibers, detergents, pharmaceuticals, and many other products.
What is enzyme washed denim?
Enzyme wash is a process that gives denim a softer and worn-in look by breaking down the cellulose molecules naturally found in indigo dyes. Enzyme washing is also more ecologically friendly due to the natural origins of enzymes, which biodegrade rather than linger in the water supply.
What is enzyme wash in garments?
Enzyme washing is a laundering process which uses enzymes to soften and finish fabric; providing jeans and other garments with a worn-in look and feel. Enzyme washing is ecologically friendly due to the natural origins of enzymes, which biodegrade, instead of lingering in the water supply.
What is stenter finishing?
Stentering is a mechanical finishing process of textile. It is done for the stretching of fabric by the stenter machine. In other words we can say stentering is done for gripping the edges of a moving web to support the web during heating and stretching operations.
What is a calender machine?
calender, machine that has wide application in the finishing of textile fabrics, the production of vinyl plastic sheeting, rubber sheeting, coated fabrics, and the manufacture of paper. The number, arrangement, and type of rollers are the chief factors that determine how the calender functions.
Which is the best description of bio finishing?
Bio-finished fabrics are free from surface hairiness hence are smoother and more lustrous. Bio-finishing is also termed as bio-polishing or bio-washing as it reduces pilling and softens the fabric hence giving it a polished look.
How are enzymes used in bio finishing process?
The enzymes for bio-finishing target the removal of the small fiber ends protruding from the fabric surface thereby reducing the hairiness or fuzz on the fabrics. The hydrolysis action of the enzyme weakens the protruding fibers to the extent that a small physical abrasion force is sufficient to break and remove them.
Which is the only finishing application of biopolishing?
Although several enzymes are now used in processing of textiles, most applications are restricted to preparatory processes like desizing, scouring and bleaching. The only finishing application is in softening of cotton with the help of cellulases in an application popularly known as biopolishing.
What is biopolishing and what does it do to fabric?
Biopolishing is a finishing process carried out before, during, or after dyeing, which increases fabric superiority by reducing hairiness and pilling of cellulose fabric leading to velvety, slicker feel, and brighter color (Ibrahim et al., 2011 ).
