Softening is either a mechanical action (in a drum) or chemical processes used to modify the properties of a fabric.
The appliqué technique consists of sewing or embroidering the border of a piece of fabric onto a larger one. The appliqué design adds texture and dimension to the fabric.
Spinning refers to any mechanical procedure to transform textile fibres into yarn to create the properties required for its use. There are two main cycles : “carding” and “combing”. Combing is an additional process after carding. This operation obtains a smoother, silkier, shinier thread with fewer short fibres. Combed materials are therefore of better quality and more expensive. Ring spinning uses spindles which exert an even twist on the fibres. The open-end method uses centrifugal force to create the yarn without twisting. Finally, self-twist or Repco spinning uses friction to create a yarn with varying twists along its length.
Spun yarn is a technical material used for filtration. It is obtained by twisting or sticking fibres together. This material is used to trap fine particles but has a poor mechanical resistance.
A textile slat is a band of woven or non-woven material (non-woven cellulose or metal) cut or produced for a decorative or useful purpose such as slatted blinds.
