Edge-crimped yarn

the heated yarn is passed over a knife-edge (edge crimping);

Edging

A narrow fabric or strip of knitted fabric, lace or embroidery, attached to another fabric or madeup article by one edge, usually for decorative purposes. (See also binding.)

Edging (seaming)

Overstitching along the edge of a fabric to prevent fraying or for ornamentation.

Edgings

Narrow laces used for trimming, with one edge straight and the other usually scalloped or indented.

Effect threads

Yams inserted in a fabric that are sufficiently different in fibre, count, or construction to form or enhance a pattern.

Egyptian tape

A tape of Egyptian-type cotton, typically R20/2tex x 9.Stex: 31 ends x 16.5 double picks per em.

Eight-lock fabric, weft-knitted

A double-faced interlock-based fabric that usually repeats over four wales. (See also double jersey, weft-knitted.)
Note.. When knitted in colour the fabric exhibits a vertical or check effect.

Elastane (fibre) (generic name)

A manufactured fibre composed of synthetic linear macromolecules having in the chain at least 85% (by mass) of segmented polyurethane groups that rapidly reverts substantially to its unstretched length after extension to three times that length. (See also Classification Table, p.401.)
Note 1: Elastane fibres typically contain hard (highly inextensible) segments alternating with soft (highly extensible) segments in the molecular chain.
Note 2.. Many elastane fibres can be extended reversibly to much more than three times their unstretched length.

Elastic binding

A light-weight elastic narrow fabric often with a scallop or picot edge.

Elastic fabric

A fabric containing rubber or other clastomeric fibres or threads, having high recoverable extensibility. (See also stretch fabric.)

Elastic limit

The greatest strain which a material is capable of sustaining without any permanent strain remaining after complete release of the stress.

Elastic narrow fabric

A term used to describe narrow fabrics incorporating elastomeric fibres, which extend when stretched and recover their original dimensions when the stretching load is removed. The principal types of elastic are:
(i) elastic web or narrow woven elastic;
(ii) elastic braid, flat or tubular;
(iii) crochet-knit elastic;
(iv) narrow elastic lace.

Elastic recovery

The immediate reduction in extension obs erved in a material when, after being held at a defined elongation for a given time, the applied force is removed.

Elasticate

1. To apply an elastomeric yarn under tension to the surface of a fabric.
2. To incorporate an clastomeric yam under tension into part of a fabric. (See also elastic fabric and stretch fabric.)

Elasticise

1. To apply an elastomeric yarn under tension to the surface of a fabric.
2. To incorporate an clastomeric yam under tension into part of a fabric. (See also elastic fabric and stretch fabric.)
