Olefin - A manufactured fiber characterized by its light weight, high strength, and abrasion resistance. Olefin is also good at transporting moisture, creating a wicking action. End-uses include activewear apparel, rope, indoor-outdoor carpets, lawn furniture, and upholstery. Also known as polyolefin and polypropylene.
Oligomer - A Simple Polymer Containing A Small Number Of Repeating Units., Note: The Oligomer Most Frequently Encountered In The Textile Industry Is The Cyclic Trimer Of Poly(ethylene Benzene-1,4-dicarboxylate) (poly(ethylene Terephthalate)), The Polymer Used For Polyester Fiber. This Material Can Form Deposits During The Processing And Dyeing Of Yarns And Fabrics.
Ombré - Refers To A Gradual Change In Shade From Light To Dark Or From One Color To Another. May Be Done As A Yarn Dye Or In Printing.
On-call Cotton - Raw Cotton Purchased Under A Procedure Whereby The Price (points On Or Off Futures) Is Between Buyer And Seller, But The Actual Futures Price Is Left To Be Fixed Within A Stipulated Period. Buyer Has The Right To 'call' (i.e., Demand Fixation Of The Futures Price) At Any Time Within Stipulated Period.
Onium Dye - A Cationic Dye That Is Solubilized By A Labile Ammonium, Sulphonium, Phosphonium, Or Oxonium Substituent Which Splits Off During Fixation To Leave An Insoluble Colorant In The Fiber.
Open Boil - Scouring Of Cellulosic Textiles With Alkaline Liquors In Open-topped Vessels At Or Near The Boiling. Note: Scours At Temperatures Lower Than The Boil Are Usually Referred To As 'steeps'.
Open End - A High Speed Yarn Spinning Process That Creates Yarn By Transferring Twist From Previously Formed Yarn To Fiber Or Sliver Continuously Fed Into The Spinning Machine. The Twisting May Be Done By Mechanical Methods, Rotors Or Air Jets.
Open-end Spinning; Break Spinning - A Spinning System In Which Sliver Feedstock Is Highly Drafted, Ideally To Individual Fiber State, And Thus Creates An Open End Or Break In The Fiber Flow. The Fibers Are Subsequently Assembled On The End Of A Rotating Yarn And Twisted In. Various Techniques Are Available For Collecting And Twisting The Fibers Into A Yarn, The Most Noteworthy Being Rotor Spinning And Friction Spinning.
Opening - The Action Of Separating Closely Packed Fibers From Each Other At An Early Stage In The Processing Of Raw Material Into Yam.
Open-shoulder construction - A method used onb better coats that is characterized by hand-sewn lining shoulder seams.
Open-width Processing - The Treatment Of Fabric At Its Full Width In The Unfolded State In Contrast To Rope-form Processing. The Fabric May Be Carried On Rollers Through The Processing Media Or Be Held On A Roller, As In Dyeing.
Optical Brightener - A Substance That Is Added To An Uncolored Or A Colored Textile Material To Increase The Apparent Reflectance In The Visible Region By Conversion Of Ultra-violet Radiation Into Visible Light And So To Increase The Apparent Brightness Or Whiteness.

Organza - A crisp, sheer, lightweight plain weave fabric, with a medium to high yarn count , made of silk, rayon, nylon, or polyester. The fabric is used primarily in evening and wedding apparel for women.
Orientation - (1) Parallelism Of Fibers, Usually As A Result Of A Combing Or Attenuating Action On Fiber Assemblies Causing The Fibers To Lie Substantially Parallel To The Axis Of The Web Or Strand. (2) A Predominant Direction Of Linear Molecules In The Fine Structure Of Fibers. Note 1: In Man-made Fibers Orientation Is Usually Parallel To The Fiber Axis As A Result Of Extrusion Stretching, Or Drawing. In Natural Fibers The Predominant Direction Is Determined During Growth, For Example A Helix Around The Fiber Axis In Cotton. Note 2: Unoriented Structures Are Those In Which Orientation Is Absent. Disoriented Structures Are Those In Which Orientation Has Been Reduced Or Eliminated As A Result Of A Disrupting Treatment
Osnaburg - A tough medium to heavyweight coarsely woven plain weave fabric, usually made of a cotton or cotton/poly blend. Lower grades of the unfinished fabric are used for such industrial purposes as bags, sacks, pipe coverings. Higher grades of finished osnaburg can be found in mattress ticking, slipcovers, workwear, and apparel.
Ottoman - A tightly woven plain weave ribbed fabric with a hard slightly lustered surface. The ribbed effect is created by weaving a finer silk or manufactured warp yarn with a heavier filler yarn, usually made of cotton, wool, or waste yarn. In the construction, the heavier filler yarn is completely covered by the warp yarn, thus creating the ribbed effect. End uses for this fabric include coats, suits, dresses, upholstery, and draperies.
Outline Embroidered - A Fabric With A Design Motif Traced (outlined) With Embroidery Stitches.
Outline Quilted - A Quilted Fabric In Which The Quilting Stitches Follow The Motif Of A Print Design.
