## Abstract

Knit structures and processes for constructing knit structures which can be used as a replacement for double layer bands in articles of clothing such as, but not limited to, pantyhose, stockings, stay ups and socks are provided.

## Claims

### Claim 1

A method for producing a knit structure with reduced curling outward and/or rolling at its fabric end without a double layer, said method comprising:
carrying yarn using cylinder needles and knitting a START part of the knit structure extending one or more courses;
dividing needles of the cylinder needles into at least two sections comprising a knit needle section and a miss needle section and producing a FALSE BAND section adjacent to the START part, said FALSE BAND comprising multiple courses of a knit stitch and a miss stitch; and
starting needles of the miss needles sections to knit and form a CLOSE part adjacent to said FALSE BAND, wherein a course of the START part is interconnected with a course of the CLOSE part resulting is a knit structure with higher tension and force toward inside of the knit structure, opposing any rolling over phenomenon without compromising the cross-stretch extension and without a double layer.

### Claim 2 (depends on 1)

The method of claim 1 wherein the knit needle section and the miss needle section follow each other and this sequence repeats for all the needles of the cylinder.

### Claim 3 (depends on 1)

The method of claim 1 wherein only knit needle sections and miss needle sections extending one needle each in a pattern of one needle knit followed by one needle miss produce the FALSE BAND section.

### Claim 4 (depends on 1)

The method of claim 1 wherein a 400 needle machine is used.

### Claim 5 (depends on 1)

The method of claim 1 wherein the FALSE BAND comprises 4 to 20 courses in total.

### Claim 6 (depends on 1)

The method of claim 1 wherein the knit structure contains polyamide yarns having between 8 and 80 dtex.

### Claim 7

A knit structure comprising a combination of stitches which provide force towards the inside of the knit structure and reduce curl outwards and subsequent roll over without a double layer, said knit structure comprising:
a START part extending one or more courses;
a FALSE BAND part adjacent to the START part comprising multiple courses of knit stitch and miss stitch; and
a CLOSE part extending one or more courses adjacent to the FALSE BAND,
wherein a course of the START part is interconnected with a course of the CLOSE part resulting is a knit structure with higher tension and force toward inside of the knit structure, opposing any rolling over phenomenon without compromising the cross-stretch extension and without a double layer.

### Claim 8 (depends on 7)

An article of manufacture at least a portion of which comprises the knit structure of claim 7.

### Claim 9 (depends on 8)

The article of manufacture of claim 8 which is article of clothing.

### Claim 10 (depends on 9)

The article of manufacture of claim 9 wherein the article of clothing is selected from pantyhose, stockings, stay ups and socks.
