Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
92 words
A method of displaying appearance properties of a warp knit fabric having a stitch pattern with courses and wales based on average yarn physical properties comprising the steps of: obtaining data set of yarn physical properties for each yarn in the warp knit fabric: averaging said yarn physical properties according to said stitch pattern to produce a wale average property for each wale in said fabric; calculating print density from said wale average properties: and displaying said print density as a display element to represent each wale in said warp knit fabric.
Claim 2
Independent Claim
92 words
A method of displaying appearance properties of a warp knit fabric having a stitch pattern with courses and wales based on average yarn physical properties comprising the steps of: obtaining data set of yarn physical properties for each yarn in the warp knit fabric: averaging said yarn physical properties according to said stitch pattern to produce a wale average property for each wale in said fabric; calculating print density from said wale average properties: and displaying said print density as a display element to represent each wale in said warp knit fabric.
Claim 3
Independent Claim
135 words
A method of displaying appearance properties of a warp knit fabric having a stitch pattern of wales based on average yarn physical properties comprising the steps of: obtaining data set of yarn physical properties for each yarn in said fabric: programming a digital computer to produce a wale average property for each wale in said fabric, said computer having graphics capability with individual pixel control of the graphics to average said yarn physical properties according to said stitch pattern; calculating pixel density from said wale average property by means of said digital computer; and displaying said pixel density as a series of rows of pixels, wherein the number of pixels in each row is proportional to said wale average property for each wale in said fabric, to represent each wale in said warp knit fabric.
