Study Notes

Knitting Terminology

  • The term for the horizontal rows of needle loops produced by adjacent needles during the same knitting cycle is course.
  • Woven fabric is produced by intersecting two sets of yarn, warp and weft, which cross and interweave at right angles to each other.

Knitting vs. Weaving

  • The main distinguishing factor between knitting and weaving in terms of the yarn used to create fabric is that knitting uses single thread while weaving uses two sets of threads.

Textile Fabric Characteristics

  • Weft knits are known for their tendency to snag or run.
  • Nalbinding is a form of looping known for producing socks recovered from fourth-century tombs in Egypt.

Knitting History

  • Reverend William Lee invented weft knitting in 1589.
  • Warp knitting was invented in 1846.

Knitting Techniques

  • Nalbinding is a method of interlocking loops to create hand and machine knitted fabric using a single sewing needle instead of two knitting needles.
  • Modernized knitting techniques like seamless garment and fully fashion garments were widely produced in Italy.

Knitted Fabric Construction

  • The depicted construction has 2 float stitches.
  • The main characteristic of a float stitch in a knitted fabric is that it is not intermeshed with the neighboring wale lines.
  • A long float in a knitted fabric is likely to cause snagging or running.
  • The distinctive feature of a tuck stitch in knitting is that it creates an extra loop on the needle.
  • A tuck stitch affects neighboring wale lines in knitted fabric by not intermeshing with them.

Simple Weft Knitted Constructions

  • The simplest of all weft knitted constructions produced on machines employing only one set of needles is plain knitting.

Structural Elements of Knitted Fabric

  • A roving is formed when the two zones of interlacement around the base are eliminated from a loop stitch.
  • A yarn segment is the straight segment of yarn that materializes when all the four binding zones around a loop stitch are removed.
  • Complex fabric constructions can be formed by combining loop, tuck, and float stitches judiciously in a knitted fabric.
  • In a hypothetical construction involving loop, tuck, and float stitches, a roving is shown in Fig. 11 of the text.
