Polyester Fibres Compatible for Blending with Cotton in Blended Fabrics: Part I—Stress-Strain Curves

Abstract

<span style="font-size:11.0pt;line-height:115%; font-family:" calibri","sans-serif";mso-ascii-theme-font:minor-latin;mso-fareast-font-family:="" "times="" new="" roman";mso-fareast-theme-font:minor-fareast;mso-hansi-theme-font:="" minor-latin;mso-bidi-font-family:"times="" roman";mso-ansi-language:en-us;="" mso-fareast-language:en-us;mso-bidi-language:ar-sa"="">An attempt has been made to alter polyester fibre properties through physical modification using simple drawing and heat setting operations with a view to producing a compatible fibre with properly matched stress-strain curves for blending with cotton. It is observed that the cold-drawn and subsequently tension heat set polyester fibres give stress-strain curves matching those for some superior cottons and therefore these fibres can be better alternatives for commercial medium and high tenacity polyester fibres normally used in India for blending with cotton for getting apparel fabrics. The new anti-pill polyester fibres can also be used for blending with cotton provided they are heat set under tension. When these fibres are stretched beyond their original length and heat set under tension, their stress-strain curves match those for most cotton fibres.</span>
