Whats a fabric
A fabric is an artifact created by the
weaving process
Fabric macro classes
- from yarns:
orthogonal fabrics,
knitted fabrics,
braids and pierced tissue. - from fibers:
non-woven (felt, needled). - Combinations: laminated fabrics
how is woven fabric obtained
obtained by weaving perpendicular two yarns: warp and weft
warp
a set of vertical yarns
weft
the only thread that crosses horizontally the warp
how is weaving of woven fabric done
done by using special machines called looms
knitted fabric
The knitted fabric is distinguished from other fabrics by the property of
having a remarkable elasticity, regardless of the yarn that composes it
knitted elasticity
The elasticity is due to the fact that the braided knitted threads act as springs, yielding to the tension and
returning to the initial position as soon as the tension ends
how is knitted fabric made
- Knitted fabric is made from a single interlacing curvilinear formed by a
single wire. - The thread is interlaced by binding by means of vertical and horizontal
crossings
knitted fabric machine
- Knitted fabrics are made on frame equipped with needles which weave the wires forming the knit.
- These particular loom can be linear or circular
hand knitting finish
All the hand knitting has completely fully fashioned, it means that the garment is made by increasing and decreasing the number of stitches in a row to create the desired shape
machine knitting division
Machine knitting is divided into
fully fashioned or cut and sew
knit
fully fashioned knitwear
- Fully fashioned knitwear is most used for expensive yarns such as cashmere or the most luxurious.
- An excellent knitwear garment will be completely made in fully fashioned knit, while a mass market product is modeled only on the sleeve point, to
eliminate waste
cut and sewn
- It is a fabric that has been knitted and then cut and sewn in a similar way to woven fabrics.
- It is mainly used for economic
yarns due to the waste suffered
basic weaves
PLAIN OR CANVAS,
TWILL,
SATIN
plain weave or canvas
- A weft thread passes over and
under each repeating warp thread. - It is the most used and simplest
method for creating fabrics, it is
also an excellent basis for
printing. - It is a simply weave that looks i
identical on both sides.
twill weave or diagonal
- It has a diagonal pattern with a straight and a reverse, it is obtained by passing the weft thread over and under two warp threads, with the scrap of one on the weft threads.
- This technique is used to create durable and structured fabrics
satin weave
- Create a luxurious and shiny hand, by sliding the weft threads over four or more warps and passing only under one.
- Satin is uniform and glossy on the warp face and matt on the weft face
plain weave fabrics
-Canvas: the easiest way to cross the warp and weft.
-Taffeta
-Muslin, lightweight, soft and transparent.
-Georgette: by silk, to haute couture.
-Chiffon: silk veil, light and transparent.
-Organza
-Baptiste: lightweight linen or cotton
canvas.
-Flannel :light and soft .
twill weave fabrics
-Twill: diagonal effect or herringbone.
-Moleskin : sturdy and smooth
-Hounds Tooth
-Prince of wales
-Denim
-Tartan
-Tweed
-Loden
satin weave fabrics
-Satin
-Damask
-Brocade
-Lampass
jacquard fabrics
- Jacquard loom is a special loom that has the ability to execute complex designs.
- This is a normal frame in which it is added a machine that enables the
automatic handling of individual warp threads
fabric weight
- The fabric weight is measured in meters.
- This means that the fabric weighs in one meter apart from its height (grams per square meter).
- Sometimes the weight of a fabric may be expressed in grams per linear meter.
