Yarn Midterm

Front 1

Smooth filament yarns

Back 1

Made with smooth, straight fibers. They are uniform in size. They have a very small amount of twist, they are smooth, lustrous, and slick

Front 2

Monofilament yarns

Back 2

Made from a single fiber (ex. Sewing thread, fishing line)

Front 3

Textured/bulk filament yarn

Back 3

Compared to smooth filament yarn, they are more comfortable, more absorbent, more permeable to moisture and air, and warmer. They are also slightly weaker. Compared to spun yarns, they do not shed, pill, or lint

Front 4

Combed yarns

Front 5

Worsted yarn

Back 5

Wool or wool blends which have undergone an extra step of combing which removes very short fibers leaving the remaining longer fibers more parallel. These are also more smooth, fine, even, and strong.

Front 6

Carded yarn

Back 6

Cotton or cotton blend yarns that have not been combed

Front 7

Woolen yarn

Back 7

Wool or wool blend yarns that have not been combed

Front 8

Twist effects :

Back 8

1. Texture / hand

2. Hairiness

3. Pilling and shedding

4. Heat retention

5. Strength/ fiber cohesion

Front 9

The longer the fiber...

Back 9

The fewer number of fiber ends on the surface

Front 10

Yarn number

Back 10

Number of 840 yard skins in one pound (the higher the number, the finer the yarn)

Front 11

Denier

Back 11

Grams per 9,000 meters of yarn

Front 12

Simple yarn

Back 12

Uniform in appearance along the entire length of the yarn

Front 13

Fancy yarn

Back 13

Not uniform on appearance along the entire length of the yarn

Front 14

Simple single yarn

Back 14

A single strand, untwistting results in loose fibers

Front 15

Simple plied yarn

Back 15

Two or more strands, untwisting results in separation of two or more strands

Front 16

Simple cord yarn

Back 16

Two or more plied yarns twisted together, untwisting results in the separation of two or more plies

Front 17

Warp yarns

Back 17

Run lengthwise direction of fabric

Front 18

Filling (weft) Yarn

Back 18

Run widthwise direction of fabric

Front 19

On grain

Back 19

When the direction of the cut of the fabric runs parallel to the selvage edge and warp yarns - more lengthwise folds

Front 20

Cross grain

Back 20

Runs parallel to the filling yarns- creates less fold

Front 21

On the bias

Back 21

When the direction of the cut of the fabric runs at a 45 ° angle to the warp yarn - creates more diagonally depending folds

Front 22

Skew

Front 23

Off grain- bow
