The distinguishing feature of all authentic Oriental rugs is
that each pile tuft is ahnd knotted

c. resist moisture
Which of the following is not a cellular rubber cushion:
a. sponge
b. urethane
c. foam
b. urethane
The degree of resistance a cushion offers to being crushed or deflected under a static load is
compressibility
One of the following is important only in cellular rubber cushions; this variable is:
a. aging
b. delamination strength
c. elongation
d. tensile strength
a. aging
aging
Characterized by cracking, crumbling, and sticking over time.
compressibility
Ease with which a textile structure can be crushed or reduced in thickness
compression deflection
Extent to which a structure restists compression force.
compression load deflection
Force required to deflect a specimen assembly a given percentage of its original thickness
compression loss
Extent to which a structure fails to recover its original thickness after being compressed under a static load
compression set
Also known as compression loss
delamination strength
Force required to separate the primary and secondary backings of tufted floor coverings
densified prime urethane foam
High density cellular cushion that is produced from a finer, elongated cellular structure; odorless, resilient, mildew-resistant, and resistant to bottoming out.
density
Mass or amount of matter per unit of volume of a fiber or other textile structure.
elongation
Ability of a fiber, yarn or other textile structure to extend.
fibrous cushion
Produced by needlepunching hair or jute fibers into felt-like structures.
foam rubber
Manufactured by converting liquid latex and fillers into flat, continuous sheets.
prime urethane foam
Manufactured by foaming the urethane polymer units into a continuous sheet.
sponge rubber
Contain chemicals, oils, and fillers that were added to the rubber compound for weight.
tensile strength
Force per unit of cross sectional area necessary to rupture a fabric.
Device used to simulate foot traffic; imparts mechanical action as a carpet-lined drum rotates
tetrapod tester
Apparatus frequently used in the accelerated laboratory testing of carpet and upholstery fabric; specimens are rotated while abradant wheels revolve over the surface
Taber tester
With regard to sound absorption, which of the following statements correctly state the permeability principle:
a. the more permeable the structure, the more efficiently it will absorb sound
b. the less permeable the structure, the more efficiently it will absorb sound
a. the more permeable the structure, the more efficiently it will absorb sound
Which of the following statements is correct:
a. textile fibers have high K-values
b. copper materials have low K-values
c. increasing the thickness of a material does not increase its K-value
d. increasing the thickness of a material increases its K-value
c. increasing the thickness of a material does not increase its K-value
R-value is equal to:
a. thickness x K-value
b. K-value/thickness
c. Thickness/K-value
c. Thickness/K-value
acoustical value
Extent to which a structure prevfents sound from becoming unwanted noise.
airborne and surface sounds
Noises such as people talking, telephones ringing, etc.
foot traffic units
Number of passes by human walkers
impart and structurally borne sounds
Sounds generated by walking, jumping, dropping items on the floor, etc.
impact noise rating
Numerical value used to indicate the effectiveness of a floor, carpet, cushion, or combination in reducing noise transmission
K-value
Rate at which a material conducts or transfers heat
light reflectance factor
Numerical value indicating the percentage of incident light being reflected by a carpet surface
noise reduction coefficient
Numerical value that indicates the effectiveness of textile floor and wall coverings at absorbing sound.
R-value
Rate at which a material resists heat flow.
