Unit 3 Lecture 18 Topic 2

Question 1

What are the basic weft knit stitches?

Answer 1

Knit, purl, tuck, and float stitches.

Question 2

Knit Stitch:

Answer 2

The most common knit stitch in which the leg of the stitch loop is on face of the fabric (head of the loop is on the back). It is also known as a jersey or plain stitch.

Question 3

Purl Stitch:

Answer 3

Also known as the reverse stitch, this stitch features the head or crown of the stitch loop on the face of the fabric (leg of the loop is on the back).

Question 4

Tuck Stitch:

Answer 4

The needle retains the previous stitch as well as picking up a new stitch. It may hold more than two stitches in some designs and can be used to create a fancy knit fabric.

Question 5

Float Stitch:

Answer 5

Also known as a miss stitch, no new stitch is formed at the needle as the yarn passes by. A floating yarn is present on the back of the fabric making it helpful in creating a fancy knit fabric.

Question 6

What are the common weft knit fabrics?

Answer 6

Single jersey, purl knit, and rib knit.

Question 7

Single Jersey Knit Fabric:

Answer 7

Also known as plain knit fabricS, there are knit stitches on face, and purl stitches on the back. They have great widthwise stretch ~2x longer than the lengthwise stretch. However, the edges of the fabric tend to curl towards the face and runs form if a loop is cut or broken.

Question 8

Purl knit fabric:

Answer 8

Produced by alternating courses of purl stitches and knit stitches. The face and back are the same, and the fabric is very extensible in all directions. This fabric is thicker than jersey knit and the courses are prominent.

Question 9

Rib Knit Fabric:

Answer 9

Rib knits are characterized by prominent wales. This is formed by alternating wales of knit and purl stitches, providing excellent widthwise stretch. The fabric is thick because of the ribbed effect. Rib knits are often used for cuffs, collars, and waistbands.
