Abstract
Abstract Course count control during heat setting of stretchable warp knit fabric is provided by selvedge knitted with the fabric and along its edges, the selvedge having a predetermined lesser stretchability than that of the fabric to serve as a limit stop to the longitudinal stretch of the fabric to provide the course count desired for the fabric.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
123 words
A process for producing a knit fabric capable of being longitudinally stretched and heat set to a predetermined course count, comprising warp knitting a longitudinally stretchable fabric of elastic and inelastic yarn and simultaneously warp knitting an additional inelastic yarn into the selvedge along each edge of said fabric, said first-mentioned inelastic yarn being overfed with respect to said additional inelastic yarn during said warp knitting, said additional inelastic yarn imparting a predetermined limit of stretchability to said selvedge which is less than the longitudinal stretchability of said fabric to limit said longitudinal stretchability during heat setting to the stretch which provides said predetermined course count, subjecting said fabric to stretching to the limit provided by said selvedge, and heat setting and fabric.
Claim 2
Dependent Claim
123 words
A process for producing a knit fabric capable of being longitudinally stretched and heat set to a predetermined course count, comprising warp knitting a longitudinally stretchable fabric of elastic and inelastic yarn and simultaneously warp knitting an additional inelastic yarn into the selvedge along each edge of said fabric, said first-mentioned inelastic yarn being overfed with respect to said additional inelastic yarn during said warp knitting, said additional inelastic yarn imparting a predetermined limit of stretchability to said selvedge which is less than the longitudinal stretchability of said fabric to limit said longitudinal stretchability during heat setting to the stretch which provides said predetermined course count, subjecting said fabric to stretching to the limit provided by said selvedge, and heat setting and fabric.
Claim 3
Dependent Claim
17 words
The process of claim 1 and additionally trimming said selvedge from said fabric after said heat setting.
Claim 4
Dependent Claim
15 words
The process of claim 1 wherein said selvedge includes said elastic yarn and is stretchable.
Claim 5
Dependent Claim
18 words
The process of claim 1 wherein said selvedge is free of said elastic yarn and is substantially non-stretchable.
