difference in performance and appearance difference between a low-twist yarn and a hightwist yarn

A high-twist yarn will be smoother and crisper than a low-twist yarn.

Side match

A problem unique to space-dyed carpet

What would be the performance and appearance difference between a small denier yarn and a thick denier yarn?

A small denier will be finer and, since there is less fiber in it, it could wear faster than a heavy denier. It will have a smoother, finer appearance.

finishing techniques apply to Oriental rugs

All are sheared; many are given a special chemical wash.

What are two organizations that aim to create a socially conscionable world rug market?

Arzurug and Rugmark

Why might your sample for approval not demonstrate your precise pattern?

Because the juxtaposition of the colors is more important than the pattern, which is better shown in the rendering.

Generation.

Changes in style preference over time

What characteristics in this product category pertain to sustainability? To safety

Designers should consider the production of the rug, e.g., were workers fairly compensated and is the production socially sustainable as well as environmentally sustainable? What chemicals are used in the production of the rug, is production (as well as use) safe with no hazards or VOCs? Can the rug be maintained without chemicals?

How can you work with out-of-town rug dealers?

Exchanging color swatches and images is one way to narrow down the search to one or 2 good examples which can be shipped to your location. You may have to pay shipping to and from your office of you do not purchase a rug that you have shipped in.

What are the different carpet cushions made of and what is the strength of each? When would you specify each?

Fiber pads are the firmest and give carpet support in high-traffic situations, frothed foam pads are high-quality pads when they are dense. Waffle pads are also good quality when dense; they attempt to provide a pad that is both dense and cushiony. Rebond pads are the most common and come in varying densities as well so there is a range of quality in this category; they may have recycled content.

techniques for making area rugs

Weaving, tufting, felting, appointing (, piecing, braiding and sewing, needlepoint

characteristics of carpet that are typically measured

materials used to make area rugs

Wool, leather, paper, plant fiber, some man-made fiber, and even metal.

difference between tufted and woven product

Woven carpets are more durable.

Why are repairs not necessarily a bad thing in old carpets?

a rug that is not valuable will not be repaired; it will be recycled or disposed of if it is not worth the effort. If repairs are well made they will not disrupt the quality of the design.

When inspecting a completed job, what will likely be on your checklist for any carpet installation?

The condition the site was left in (e.g., clean with scraps removed, check the location and quality of the seams, did they follow the approved seaming diagram and are the seams wellmade?). Is the carpet smooth with no wrinkles and are the transitions installed as described with good-quality workmanship?

How would you qualify an appropriate installer for your job?

See if they have completed any training programs pertinent to your installation or if they have installed product like yours on a jobsite with conditions like your client site. Bid competitively to confirm a fair price. If the installer is new to you, review his or her previous installations.

production process for a custom rug

Select a kind of custom rug and find a craftsperson Decide on a design, either a semi-custom or custom, and work with the fabricator to determine, with samples and drawing, what the construction, materials, and colors will be.

How can you specify for sustainability?

Select carpet that has recycled content, comes from renewable or sustainable sources (like wool or soda bottles), is constructed to be recycled, and comes from a source that will take it back at the end of its life and recycle it. Specify modular carpet tiles to extend the life of the installation. Address toxicity in the selection of pad as well as carpet components.

What kinds of health and safety issues pertain to carpet?

Select carpet that will not off-gas in the space while the client is using it. If clients have allergies, they may not be able to tolerate carpet at all. Carpet is slip-resistant and less likely to break things that fall to the floor.

indications of quality for Oriental rugs

The quality of the materials used to make them, usually cotton warps and wool wefts as well as the appropriateness of the components for the design, a high knot-count for intricate patterns. The design of the rug is personal but there will be some objective evaluation possible as well. If the rug is rare in some way, it may command a higher price, which is a quality consideration for some people.
