Quiz 1 Flashcards
A very large molecule made by connecting many small molecules together. Almost all fibers are polymers made of organic materials, but some polymers are formed into thin films and used as textiles. For example, vinyl upholstery is a film, often applied to a more traditional textile knit or woven material for added durability.
Polymer
Any substance, natural or manufactured, with a high length-to-width ratio possessing suitable characteristics for being processed into fabric; the smallest component, hairlike in nature that can be separated from a fabric; can be absorbent (like cotton and rayon), stretchy (like spandex), warm and bulky (like wool), or very strong and abrasion resistant (like nylon and polyester)
Fiber
An assemblage of fibers that is twisted or laid together so as to form a continuous strand that can be made into a textile fabric; can be used to make a fabric that is smooth and slick like satin or soft and fuzzy like brushed denim
Yarn
A flexible planar substance constructed from solutions, fibers, yarns, or fabrics, in any combination; range from lightweight and sheer chiffon scarves to heavy and sturdy denim to rigid and from carpeting to technical products such as erosion control and medical tapes. Cloth and material are common synonyms
Fabric
A term originally applied only to woven fabrics, now generally applied to any flexible material that is composed of thin films of polymers or of fibers, yarns, or fabrics or products made of these materials.
Textile
Any fabric that has not been finished. Consumers rarely see these, except for home sewers and quilters who may work with muslin.
Gray goods
Any dyeing or printing process used to add color with dyes or pigments to a textile; adds interest and fashion appeal to apparel and interiors.
Coloration
Any process that modifies appearance or enhances performance of gray goods. Some make the fabric more comfortable such as brushing velveteen to produce the soft surface. With others, the consumer cannot determine the presence of it.
Finish
Products constructed of textiles and other flexible materials including apparel, interior textiles, and technical textiles
Soft goods
Clothing and accessories made from flexible materials.
Apparel
Also known as interior furnishings or home fashions; describe textiles and textile products used in the home and other building interiors for functions such as absorbency or to add comfort and visual interest
Interior textiles
The application or function for which a textile is designed or for which it is ultimately used
End use
Sense and react to the environment or stimuli of an electrical, chemical, thermal, mechanical, magnetic, or other nature.
Smart textiles/fabrics
Include a broad range of materials that are widely used in special applications of a technical nature and that are generally not considered apparel or furnishings.
Technical or industrial textiles
The design and engineering of a product so that it has the desired serviceability characteristics, appeals to the target market, can be made within an acceptable time frame for a reasonable cost, and can be sold at a profit. It encompasses a range of activities and differs widely by companies and segments of the global textiles complex.
Product development
The measure of a textile product’s ability to meet consumers’ needs. The emphasis is on understanding the target market and relating target market needs to the product. These concepts are aesthetics, durability, comfort, safety, appearance retention, care, environmental concerns, sustainability, and cost.
Serviceability
The appearance or attractiveness of a textile product.
Aesthetics
The manner in which the product withstands use, or the length of time the product is considered suitable for the use for which it was purchased.
Durability
The way textiles affect heat, air, and moisture transfer, and the way the body interacts with a textile product
Comfort
A textile’s ability to protect the body from harm
Safety
How the product maintains its original appearance during use and care
Appearance retention
The treatment required to maintain a textile product’s original appearance and cleanliness
Care
The impact that the production, use, care, or disposal of a textile has on the environment.
Environmental concerns
Practices and policies that reduce environmental pollution and do not exploit people or natural resources in meeting the lifestyle needs of the present without compromising the future.
Sustainability
The way the production, use, care, and disposal of a product affects the environment and the people involved with the product
Life cycle impact
The amount paid to acquire, use, maintain, and dispose of a product
Cost
The manner in which a textile, textile component, or textile product responds to use or when exposed to some mechanical or environmental factor that might adversely affect it
Performance
The sum total of product characteristics such as appearance, end use, performance, material interactions within the product, consistency among identical products, and freedom from defects in construction or materials
Quality
Grown or developed in nature in recognizable fiber form
Natural fibers
Made from chemical compounds produced in manufacturing facilities. The material’s original form is not recognizable as a fiber.
Manufactured fibers
Any natural or manufactured fiber produced in or cut to a short length measured in inches or centimeters
Staple fibers
Fibers that are extremely long or yarns made of these fibers
Filaments
An intermediate stage in the production of staple manufactured fibers when manufactured fibers are produced in large bundles in filament length and crimped prior to cutting or breaking into staple fibers
Filament tow
Yarn or manufactured fiber size that is defined as weight in grams for 9,000 meters of fiber or yarn
Denier
A direct yarn-numbering system, also used to express fiber size; yarn or fiber size is the weight in grams of 1,000 meters of yarn
Tex
A way of describing fiber size; calculated by dividing the yarn size in denier by the number of filaments
Denier per filament (DPF)
Waves, bends, twists, coils, or curls along the length of the fiber
Fiber crimp
Fibers with similar chemical composition
Generic group
The process of connecting many small molecules (monomers) to produce one very large molecule, called a polymer
Polymerization
The number of small molecules (monomers) connected to form a polymer
Degree of polymerization
A random or disorganized arrangement of molecular chains within a fiber
Amorphous
Molecular chains that are parallel to each other in a fiber or in regions within a fiber
Crystalline
Refers to the alignment of the fiber’s polymers with its longitudinal axis
Orientation
The process of pulling a fiber so that the molecular chains rotate and slide until they become oriented and form crystals within the fiber to enhance certain fiber properties
Stretching
A fiber-finishing step in which a manufactured fiber is elongated after spinning to alter the molecular arrangement within the fiber, increasing crystallinity and orientation and resulting in a change in specific performance properties
Drawing
Attractions between positive hydrogen atoms of one molecule and negative oxygen or nitrogen atoms in another molecule
Hydrogen bonds
