Between knit and woven fabrics, which are looped
Woven fabrics ▪ Interlacing two sets of yarns at right angles to each other.
▪ Yarns that run lengthwise are called warp yarns.
▪ The crosswise yarns are called filling yarns.
Lengthwise yarns for woven fabrics are called
wrap yarns
Crosswise yarns for woven fabrics are called
Filling wraps
Lengthwise yarns for knit fabrics are called

Describe the following finishes
Ciré
b) Napping
c) Lustering
d) Embossing
e) Water-Repellent
f) Waterproo
Ciré-A super glossy finish created by
applying wax
b) Napping-Fabric is made to look old and
worn through bleach, dye,
friction and ripping
c) Lustering-▪ Heat and pressure are applied
to add lustre (shine)
d) Embossing- Fabrics are given a raised design
on their surface. Various
techniques are used to raise the
fabric
e) Water-Repellent-▪ Resists water, but will eventually
become wet
f) Waterproof- Has been coated so no water will
penetrate
What are three eco-friendly fabrics
Organic cotton, hemp, eco fleece
Why are each of these fabrics considered eco-friendly?
Organic cotton
▪ Grown without the use of chemical inputs.
▪ People and environment are less exposed to chemicals.
Hemp
▪ Biodegradable at the end of its life.
▪ The hemp plant does not require a lot of water.
▪ It actually replenishes the soil it grows in rather than extracting its nutrient
Eco fleece
▪ Though fleece is made from polyester, a petroleum by-product, many
companies are now making fleece from used plastic bottles.
