Woven, Non-Woven and Knitted Textile Construction
From Fibre to Fabric
Choosing the right fibre is only the beginning. The way fibres are assembled into a fabric structure determines how the final textile performs—its strength, drape, stretch, durability and appearance. Three major construction methods exist: weaving (interlacing two sets of yarns at right angles), knitting (looping a single yarn into interlocking stitches) and non-woven processes (bonding fibres directly into a sheet without spinning or weaving). Each gives a different combination of properties.
Woven Fabrics
Weaving interlaces two sets of yarn. The yarn running lengthways on the loom is the warp; the yarn running crossways (inserted by a shuttle or rapier on each pass) is the weft. The pattern of interlacing determines the weave structure. The three fundamental weaves are:
Plain weave is the most basic and most common construction. The weft passes over one warp thread and under the next, reversing on the following row. This produces a symmetrical, grid-like pattern that is the same on both sides. It has the most interlacement points of any weave, which gives it:
- High durability—many interlacement points mean yarns are held firmly.
- Low drape—the firm structure does not hang or flow easily.
- Tendency to fray—cut edges must be finished or seamed.
Examples: cotton calico, muslin, taffeta, canvas. Used in shirts, bags, sails and base fabrics for printing.
Twill weave passes the weft over two (or more) warp threads before going under one, shifting by one thread on each row. This creates the characteristic diagonal rib line visible on the fabric surface. Properties:
- Better drape than plain weave—fewer interlacement points allow yarns to move more freely.
- Good abrasion resistance—the diagonal rib distributes friction across a larger yarn area.
- Can be woven more tightly—so it can be heavier and more windproof than plain weave at the same yarn count.
Examples: denim (2/1 twill with indigo-dyed warp), herringbone, gabardine. Used in jeans, suits, uniforms and upholstery.
Satin weave has warp threads floating over four or more weft threads before interlacing. The very few interlacement points mean long yarn floats lie flat on the surface, creating the fabric’s characteristic smooth, high-sheen appearance. Properties:
- Excellent drape—minimal interlacement allows the fabric to hang fluidly.
- Lustrous surface—long yarn floats reflect light uniformly.
- Snagging risk—long floating yarns catch easily on rough surfaces.
- Distinct face and back—the two surfaces look very different.
Examples: silk satin, polyester satin, sateen (using cotton). Used in eveningwear, linings, bedding and decorative trims.
Plain weave has the most interlacement points—making it the most durable but with the least drape. Twill weave has a diagonal rib; it drapes better and resists abrasion well (hence denim). Satin weave has long yarn floats creating a lustrous surface with excellent drape but a snagging risk.
Non-Woven Fabrics
Non-woven fabrics are produced without spinning or weaving. Fibres are laid as a web and bonded together by one of three methods: mechanical entanglement (needle-punching or hydroentangling), thermal bonding (melting a proportion of synthetic fibres to fuse the web) or chemical bonding (applying an adhesive binder).
- Felt—produced by applying heat, moisture and mechanical pressure to wool or other protein fibres. The microscopic scales on wool fibres interlock and mat together permanently. Felt does not fray when cut (because there is no woven structure to unravel), making it easy to cut to shape for craft, padding, and industrial gaskets. However, it has low tensile strength compared with woven fabrics.
- Bonded fabrics—include interfacing used in garment construction (fusible interfacing is bonded to the wrong side of a fabric with heat to add stiffness), geotextiles used in civil engineering for soil stabilisation and drainage, and medical non-wovens (disposable gowns, masks) where single-use hygiene is prioritised over durability.
Knitted Fabrics
Knitting uses a single yarn looped into interlocking stitches. The two main types are:
- Weft knit—the yarn runs horizontally across the fabric. Stitches in a row interlock with those in the row below. Weft knit fabric stretches easily in both directions and is comfortable against skin. It also ladders—if a stitch breaks, the column can unravel downward. Used in T-shirts, underwear, socks and casual knitwear. Can be produced on circular or flat-bed knitting machines at high speed.
- Warp knit—multiple yarns run simultaneously in the warp (lengthways) direction, each forming loops that interlock with adjacent yarns on each course. The fabric is much more stable dimensionally than weft knit—it does not ladder easily. Used in lingerie, swimwear linings, velvet backing and sports mesh. Generally produced on specialist Raschel or Tricot machines.
Weft knit runs the yarn horizontally; it stretches comfortably but can ladder if a stitch breaks. Warp knit uses multiple yarns running vertically and interlocking sideways; it is dimensionally stable and does not ladder, making it suitable for swimwear and lingerie linings.
This table summarises how fabric construction affects key performance properties:
| Construction | Stretch | Drape | Durability | Fraying risk | Key application |
|---|---|---|---|---|---|
| Plain weave | Low | Low | High | Yes | Shirts, canvas bags |
| Twill weave | Low | Medium | High | Yes | Denim, suits |
| Satin weave | Low | High | Medium | Yes (floats snag) | Eveningwear, linings |
| Felt (non-woven) | Low | Low | Low | None | Craft, gaskets, padding |
| Weft knit | High | Medium | Medium | Ladders | T-shirts, underwear |
| Warp knit | Low–medium | Medium | High | None | Swimwear, lingerie |
