Fibre properties moisture regain

The chemical modifications of polyester is mainly intended to overcome some of the inherent drawbacks of the fibre such as low dyeability, low moisture regain, static accumulation, soiling tendency, pilling property and flammability. Develop-... [Pg.28]

The property profile of cellulose-based plastics and cellulose products used in typical plastics applications covers a broad range where the intrinsic cellulose properties can be recognized to different degrees. So, hydrophilicity is a prominent feature for pure cellulose products, which is reduced as the number of ester substituents and their chain length is increased. Equilibrium moisture content of cellulose fibres, for example, is around 12% while the moisture regain of diacetate fibres is 6.5% and of triacetate fibres 3.2% [43]. In this respect, propionic and butyric esters are superior when fully substituted, but even mixed esters of the CAP and CAB types... [Pg.52]

With the processes described in sections 3.4.1 and 3.4.2.3, fibres wifh excellenf fexfile properties can be produced. The high moisfure regain of fhe hydrophilic cellulose sfrucfure predestine these fibres for moisture regulation in textile structures either alone or in combination with synthetic fibres. [Pg.53]

There are two types of Zylon fibres Zylon HM (high modulus) has greater tensile modulus and less moisture regain than Zylon AS (as spun). The properties of Zylon AS and HM fibres are shown in Table 3.4. ... [Pg.100]
