By no means comprehensive! I have tried to stick to the terms most useful for reenactors or reproductions sewers.
Basket Weave
A variation of the plain weave construction, formed by treating two or more warp yarns and/or two or more filling yarns as one unit in the weaving process. Examples of basket weave construction includes monk cloth and oxford cloth.

Batiste
A medium weight plain weave fabric, usually cotton.

Boucle
A knit or woven fabric made with curly boucle yarn. Fabric will have a looped or knotted surface.

Broadcloth
Plain weave, tightly woven fabric with a slight ridge in one direction. Made from cotton or blends.

Brocade
A heavy, exquisite jacquard type fabric with an all-over raised pattern or floral design.

Burlap
A loosely constructed, heavy weight, plain weave fabric used as a carpet backing or sacking.

Calico
A tightly-woven cotton type fabric with an all-over print, usually a small floral pattern on a contrasting background color.

Challis
A lightweight, soft plain weave fabric with a slightly brushed surface. The fabric is often printed, usually in a floral pattern. Challis is most often seen in fabrics made of cotton, wool, or rayon.

Chintz
Cotton fabric, which has been glazed to produce a polished look.

Crinoline
A lightweight, plain weave, stiffened fabric. For use in slips or petticoats.

Damask
A glossy jacquard fabric, usually made from linen, cotton, rayon, silk, or blends. The patterns are flat and reversible. The fabric is often used in napkins, tablecloths, draperies, and upholstery.

Dobby Weave
A decorative weave, characterized by small figures, usually geometric, that are woven into the fabric structure.

Duck
A tightly woven, heavy, fabric with a hard, durable finish. Good for haversacks.

Faille
A glossy, soft, finely-ribbed silk-like woven fabric made from cotton or silk.

Flannel
A medium-weight, plain or twill weave fabric that is typically made from cotton, a cotton blend, or wool. The fabric has a very soft hand, brushed on both sides to lift the fiber ends out of the base fabric and create a soft, fuzzy surface.

Gingham
A medium weight, plain weave fabric with a plaid or check pattern.

Hand
The way the fabric feels when it is touched. Terms like softness, crispness, dryness, silkiness are all terms that describe the hand of the fabric.

Jacquard
Woven fabrics manufactured by using the Jacquard attachment on the loom. This attachment provides versatility in designs and permits individual control of each of the warp yarns. Thus, fabrics of almost any type or complexity can be made. Brocade and damask are types of jacquard woven fabrics.

Jute
A bast fiber, chiefly from India, used primarily for gunny sacks, bags, cordage, and binding threads in carpets and rugs.

Lawn
A light, fine cloth made using carded or combed, linen or cotton yarns. The fabric has a crease-resistant, crisp finish. Linen lawn is synonymous with handkerchief linen. Cotton lawn is a similar type of fabric, which can be white, solid colored, or printed.

Linen
A fabric made from linen fibers obtained from inside the woody stem of the flax plant. Linen fibers are much stronger and more lustrous than cotton. Linen fabrics are very cool and absorbent, but wrinkle very easily, unless blended with manufactured fibers. Linen is one of the oldest textile fibers.

Moiré
A corded fabric, usually made from silk or one of the manufactured fibers, which has a distinctive water-marked wavy pattern on the face of the fabric.

Muslin
An inexpensive, medium weight, plain weave, low count (less than 160 threads per square inch) cotton sheeting fabric.

Osnaburg
A tough medium to heavyweight coarsely woven plain weave fabric, usually made of a cotton or cotton/poly blend.

Paisley
A tear-drop shaped, fancy printed pattern, used in dresses, blouses, and men's ties.

Poplin
A fabric made using a rib variation of the plain weave. The construction is characterized by having a slight ridge effect in one direction, usually the filling. Poplin used to be associated with casual clothing, but as the "world of work" has become more relaxed, this fabric has developed into a staple of men's wardrobes, being used frequently in casual trousers.

Satin Weave
A basic weave, characterized by long floats of yarn on the face of the fabric. The yarns are interlaced in such a manner that there is no definite, visible pattern of interlacing and, in this manner, a smooth and somewhat shiny surface effect is achieved. The shiny surface effect is further increased through the use of high luster filament fibers in yarns which also have a low amount of twist. A true satin weave fabric always has the warp yarns floating over filling yarns.

Selvage or Selvedge
The thin compressed edge of a woven fabric which runs parallel to the warp yarns and prevents raveling. It is usually woven, utilizing tougher yarns and a tighter construction than the rest of the fabric.

Silk
A natural filament fiber produced by the silkworm in the construction of its cocoon. Most silk is collected from cultivated worms; Tussah silk, or wild silk, is a thicker, shorter fiber produced by worms in their natural habitat. All silk comes from Asia, primarily China.

Taffeta
A lustrous, medium weight, plain weave fabric with a slight ribbed appearance in the filling (crosswise) direction. For formal wear, taffeta is a favorite choice. It provides a crisp hand, with lots of body. Silk taffeta gives the ultimate rustle, but other fibers are also good choices.

Ticking
A tightly woven, very durable fabric, usually made of cotton, and used for covering mattresses, box springs, pillows, and work clothes. The fabric can be made by using a plain, satin, or twill weave construction.

Twill Weave
A basic weave in which the fabrics are constructed by interlacing warp and filling yarns in a progressive alternation which creates a diagonal effect on the face, or right side, of the fabric. In some twill weave fabrics, the diagonal effect may also be seen clearly on the back side of the fabric.

Voile
A crisp, lightweight, plain weave cotton-like fabric, made with high twist yarns in a high yarn count construction. Similar in appearance to organdy and organza. Used in blouses dresses and curtains.

Warp
In woven fabric, the yarns that run lengthwise and is interwoven with the fill (weft) yarns.

Weft
In woven fabric, the filling yarns that run perpendicular to the warp yarns.

Wool
Usually associated with fiber or fabric made from the fleece of sheep or lamb. However, the term "wool" can also apply to all animal hair fibers, including the hair of the Cashmere or Angora goat or the specialty hair fibers of the camel, alpaca, llama, or vicuna.

Worsted Fabric
A tightly woven fabric made by using only long staple, combed wool or wool-blend yarns. The fabric has a hard, smooth surface. Gabardine is an example of a worsted fabric.

Woven Fabric
Fabrics composed of two sets of yarns. One set of yarns, the warp, runs along the length of the fabric. The other set of yarns, the fill or weft, is perpendicular to the warp. Woven fabrics are held together by weaving the warp and the fill yarns over and under each other.

Yarn
A continuous strand of textile fibers created when a cluster of individual fibers are twisted together. These long yarns are used to create fabrics, either by knitting or weaving.
