Chapter 11 &12 Textiles and environment/ care &renovation Flashcards
*Environmentally friendly
consumers and the investment community like firms that are a “friend to the environment”
Contaminated –
substances that are detrimental to the environment
*Biodegradable –
ability to degrade quickly
Green Product Characteristics
*Green product –
color green symbolizes product that is favorable to the environment
All aspects of the product should be examined when evaluating its green characteristics. This
includes production, shipping, use, care, and disposal.
Sustainability
indicates products’ impact on the full environmental systems over the lifetime of the product
Renewable –
material that comes from a resource that is easy to replace or replenish
*Plants
*Animals
*Recycled materials
Resource conservation –
products made using less natural resources
Energy saving –
products produced using reduced energy or products requiring less energy when used
*Nonhazardous –
materials that do not harm the health or safety of an individual or the environment
Recycling –
used products that are considered waste but are used again to make other products
Cradle-to-cradle –
focus on reclaiming and recycling post-industrial and post-consumer materials into useful products
Worker assessment –
assessment of human rights
Cost Consideration –
Cost should include dollars and green rating
Eco-Friendly Textiles
Organic cotton –
government certified three years or more of organic farming practices
Transition cotton –
cotton produced on land that has been organically farmed for less than three years
*Textile industry has become more eco-friendly with:
*Fibers
*Yarns and Fabrics
*Dyeing and printing
*Finishing
*Care of products
*Recycling programs
what 5 Plant fibers as a source of sustainability:
*Hemp
*Ramie
*Bamboo
*Organic cotton
*Organic wool
Yarns and Fabrics non eco friendly factors
*There are many non-eco-friendly conditions for yarns and fabrics
*Production of cotton yarns and fabrics: contaminants become air-borne
*Energy consumption should also be considered
dyeing and printing non eco friendly factors
*Potential for adverse impact on the environment
*Dyes and pigments can create problems with photosynthesis
*Manufacturers are typing to reduce energy and water consumption
finishes non eco friendly factors
*Finishing has potential to damage the environment
*Industry has developed initiatives to become “green”:
*Reduced usage of dangerous finishing chemicals
*Restrictions on waste discharge
*New processes in continuous bleaching
*Carbon dioxide assessments
Finishing non eco friendly factors
*Large amounts of water
*Chemicals
*Large amounts of energy
what is Organic Standards
*Various countries are adopting a Global Organic Textile Standard (GOTS)
what soil can be removed just with water
soda and coffee
what soil must be removed with soap
fruit and veggies
*Laundering
water combined with soaps or detergents, and other additives for soil removal
*Soaps
sodium salts of a fatty acid
Detergent
synthetic detergents produced by chemical synthesis
*Soil Removal –
Soap and detergent decrease the surface tension of water then help to dislodge soil from fabric
*Additives –
added to wash water, or contained in the detergent bottle
*Surfactants –
substances that lower the surface tension
*Bleaches –
oxidize coloring matter
*Fluorescent Brighteners –
absorbs ultraviolet rays and reflects light
*Water Softeners
combine with the minerals that cause the water to be hard to remove the bonded molecules
Fabric softeners
add a film on fibers to make fabrics softer minimize wrinkles
*Starches
are sizing to help restore the body to limp fabrics
*Fragrances –
added to give a “clean” smell and mask any chemical odor
Pretreatment –
necessary for some types of stains, such as protein-based stains like body soils, blood, eggs, grass stains, and chocolate
Enzymes –
organic substances that break down certain soils
Dry cleaning
Dry cleaning
articles are cleaned in an organic solvent cleansing fluid and tumbled in a machine
*cleaning liquid is not water based
*Spotting
articles stained with substances that are insoluble in dry cleaning solvent such as
*Blood
*Ink
*Rust spots
drycleaning solvents
*Perchlorethylene
*Hydrocarbons
*Stoddard
*New developments – liquid CO2
Water-Repellent Garments –
need special attention when dry cleaned
Cautions in Dry Cleaning
*Vinyl plastics and vinyl-coated fabrics
*Polystyrene plastics
*Dyed leather trim
*Pigment-colored fabrics
*Flocked, bonded, laminated, or cemented
*Heavy and light fabrics
*Liquor, coffee, tea, or juices
Home Solvent Cleaning –
heat activates the solvent in moist cloth and the tumbling in home dryer encourages the cleaning action
*Ultrasonic –
sound above the human hearing range
Ultrasonic Washing –
agitation generated by ultrasonic
Dissolves contaminants
*Displaces contaminants
