Abstract
Abstract This disclosure teaches a method for integrated finishing and compressive preshrinking of a high-shrinkage fabric. The fabric is brought damp from being finished to being compressively preshrunk, rather than according to universally recognized procedure of causing all goods which are to be compressively preshrunk to be in their dry state before the compressive-preshrinking operation. A padder is here employed to impregnate the fabric with finishing liquid, then a series of hot cans reduce the moisture content of the fabric to a range of from 10 to 30%. A moisture content of 15% is preferred. In blended fabrics of cellulosic and man-made fibers, the need for this moisture content is only in the cellulosic component. From the hot cans the fabric is introduced to a compressive-preshrinking unit and the fabric is subsequently dried in a felt-belt dryer.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
103 words
A method for continuously manufacturing, finishing and preshrinking fabric, the method comprising the sequential steps of: creating fabric by using conventional machinery, said fabric being known as greige fabric which has been stretched in said machinery and is susceptible therefor of relatively high shrinkage after washing, taking said greige fabric from said machinery to a padder and impregnating said greige fabric with a finishing liquid therein including starch to a moisture content in excess of 50% by weight, partially drying the fabric, measuring and maintaining a moisture content between 10% and 30% by weight, compressively preshrinking the fabric, and fully drying the fabric.
Claim 2
Independent Claim
103 words
A method for continuously manufacturing, finishing and preshrinking fabric, the method comprising the sequential steps of: creating fabric by using conventional machinery, said fabric being known as greige fabric which has been stretched in said machinery and is susceptible therefor of relatively high shrinkage after washing, taking said greige fabric from said machinery to a padder and impregnating said greige fabric with a finishing liquid therein including starch to a moisture content in excess of 50% by weight, partially drying the fabric, measuring and maintaining a moisture content between 10% and 30% by weight, compressively preshrinking the fabric, and fully drying the fabric.
Claim 3
Dependent Claim
22 words
A method according to claim 1 wherein the finishing liquid includes starches in combination with lubricants, rewetters, hand modifiers and the like.
Claim 4
Dependent Claim
35 words
A method according to claim 1 wherein greige blue denim fabric taken directly from a loom is subjected to impregnation with said finishing liquid, is partially dried, is compressively shrunk and is then fully dried.
Claim 5
Independent Claim
122 words
A method for continuously manufacturing, finishing and preshrinking fabric, the method comprising the sequential steps of: creating fabric by using conventional machinery, said fabric being known as greige fabric which has been stretched in said machinery and is susceptible therefor of relatively high shrinkage after washing, taking said greige fabric from said machinery to a padder and impregnating said greige fabric with a finishing liquid therein including starch to a moisture content in excess of 50% by weight, passing the fabric over a series of hot cans to partially dry the fabric, measuring and maintaining a moisture content in the fabric between 10 and 30% by weight, compressively preshrinking the fabric in a rubberbelt compressive preshrinking unit, and fully drying the fabric.
Claim 6
Independent Claim
