Abstract
A method for producing environmentally friendly fabric and textile products without use of chemicals comprises a finishing process including the steps of: singeing, enzyme desizing; water washing, peaching, stentering, and sanforizing. The steps of the finishing process are purely physical and preferably uses only water, water vapor (steam), and enzymes, and not chemicals including chemical agents. As such, the finishing process is believed to be environmentally friendly.
Claims20
A method for producing a fabric, comprising the steps of:
- (a) singeing a continuous length of a fabric;
- (b) after said step (a), desizing the continuous length of fabric;
- (c) after said step (b), washing the continuous length of fabric;
- (d) after said step (c), peaching the continuous length of fabric by impacting at least one of the surfaces of the fabric with a plurality of bristles;
- (e) after said step (d), stentering the continuous length of fabric;
- and
- (f) after said step (e), sanforizing the continuous length of fabric;
- (g) wherein said steps (a) through (f) are performed using only water, water vapor, and enzymes without use of chemicals.
A method for producing a fabric, comprising the steps of:
- (a) singeing a continuous length of a fabric by passing the fabric on a singeing machine at a predetermined speed, wherein the continuous length of fabric in the singing machine is subjected to a gas singe having a flame temperature about 800° C. to 1000° C. and operating at a speed of 80 meters per minute to 100 meters per minute;
- (b) after said step (a), enzymatic desizing the continuous length of fabric, wherein the enzymatic desizing takes place in a desizing machine in which enzymes are introduced at a temperature of 60° C. to 80° C. to react with the continuous length of fabric for about six to eight hours;
- (c) after said step (b), washing the continuous length of fabric with water having a temperature of about 85° C. to 95° C. at a speed of about 50 to 60 meters per minute;
- (d) after said step (c), peaching the continuous length of fabric by impacting at least one of the surfaces of the fabric with a plurality of diamond shaped ceramic crystals provided on a rotating cylinder which contacts at least one of the continuous length of fabric surfaces;
- (e) after said step (d), stentering the continuous length of fabric using a stenter machine such that a generally uniform width of the continuous length of fabric is provided;
- and
- (f) after said step (e), sanforizing the continuous length of fabric using a sanforizing machine, wherein the continuous length of fabric is passed between a rubber sleeve and a heated rotating cylinder having a temperature of about 50° C. to 60° C.;
- (g) wherein said steps (a) through (f) are performed using only water, water vapor, and enzymes without use of chemicals.
A method for producing a fabric, comprising the steps of:
- (a) passing a continuous length of a fabric of a predetermined width on a singeing machine at a predetermined speed;
- (b) subjecting the fabric treated with the singeing machine to an enzymatic desizing;
- (c) washing the fabric obtained from the enzymatic desizing;
- (d) impacting at least one of the surfaces of the fabric with a plurality of bristles;
- (e) passing the fabric treated by the bristles to a stenter machine;
- and
- (f) transferring the fabric obtained from the stenter machine to a sanforizing machine;
- (g) wherein the steps are performed without use of chemicals.
