CTD 261 FINAL EXAM| 98 QUESTIONS
AND ANSWERS (ALREADY GRADED A)
Web Stabilization - ANSWER-Can be done by mechanical entanglement, heat and
pressure, and adhesives
Fiberfill - ANSWER-fiber staple made especially for filler
Multicomponent Fabrics - ANSWER-Fabrics that combine several primary and/or
secondary textile structures, at least one of which is a recognized textile structure, into a
single structure.
Types of Multicomponent Fabrics - ANSWER-Carpets: uncut or cut tufted pile
Quilts: generally 3 components including face and backing fabric and inner batt of fiber
or filling. Sewn together with thread
Flocked Fabrics: made by gluing short fibers on surface of fabric either covering entire
surface or specific pattern
Hybrid Fabrics - ANSWER-Coated fabrics: fabric coated with thin polymer film to
provide protection or stimulate leather. Vinyl, Neoprene
Poromerics: film very thin and microporous, membrane, allow passage of water
(permeable) but not liquid water
Stitch Bonded - ANSWER--Made from yarns laid down in warp and fill direction
crosswire, then stitched through with a third set of yarns
-The pattern of chain knit stitches that hold the yarns together are easy to identify
-This fabric is often used in upholstery
Nonwoven Fabrics - ANSWER-Fabrics made directly from fibers without first processing
the fibers into yarns
-production rate very fast and inexpensive
Nonwoven fabric uses - ANSWER--Use in apparel is limited bc of poor draping ability
-Used in interlinings to stiffen certain areas in garments such as collars and cuffs
-Extensive use in medical textiles as absorbent pads
Nonwoven production - ANSWER--Normally made from extruded continuous filaments
or fibrous webs strengthened by various techniques
, Two basic steps are involved in making Nonwovens - ANSWER--Formulation of a fiber
web
-Stabilizing the fiber web
Web-formation - ANSWER--Webs of staple fiber may be made by wet or dry methods
-Directly from extrusion
Shearing - ANSWER-for pile fabrics, surface pile is cut to control the pattern and
appearance
Desizing - ANSWER-Warp size is removed with enzymes
Singeing - ANSWER-Protruding fiber ends are burned off
Cleaning-Scouring - ANSWER-All greige goods are cleaned before treatments can be
added. Fabric is washed to remove natural impurities and any processing diet
Biopolishing - ANSWER-Cellulase enzyme treatments to clean fuzz from cellulose and
blend fabrics
Bleaching - ANSWER-Fabric is bleached to increase whiteness and absorbency
Mercerizing - ANSWER-Fabric is momentarily immersed in strong NaOH solution while
under tension, then rinsed
Tentering - ANSWER-Drying a fabric to specific width and length. Yarns straightened
Carbonizing - ANSWER-Wool fabrics. Removes any cellulosic impurities
Finishing - ANSWER-Changes or enhances the performance
Adds cost and time
Difference between Dyes and Pigments - ANSWER--Dyes are colorants that enter the
textile fiber at the molecular level
-Pigments are larger agglomerates of colorant molecules which are far too large to
diffuse into the fiber and need to be physically attached to the fabric surface
-Dyes can be dissolved or dispersed in water
-Pigments are insoluble color particles that are held on the surface of the fabric
-Textiles may be dyed at any stage of production, but pigment application is usually
done to textiles in fabric form
