Fibres, bicomponent

Even though it is not the subject of finishing but of coloration, it is remarkable in this context that the beautifully coloured wings of butterflies inspired Japanese fibre chemists to produce multilayer bicomponent fibres with different interference colours without the use of any dyestuff or pigment. ... [Pg.204]

Bicomponent fibres are sjmthetic fibres composed of two firmly but separately combined polymers of different chemical and physical structures. The structure of the bieomponent depends on the shape of the spinnerette orifice (side-by-side, sheath eore, matrix - fibril and multi-fibrillary) and the type of spinning method. Due to the structural differences, the two components shrink differently on heat treatment and form crimp and greater bulk in the fibre. The first fully synthetic bicomponent was an acrylic (Sayelle, Orion 21). The use of sheath-core fibres composed of nylon 6,6 and nylon 6 (Heterofil, ICI) for floor coverings is described. [Pg.43]

Modified bicomponent fibres of cover/core type were obtained by the admixture of special additives into the... [Pg.64]

The bicomponent fibres are suitable for felts, needle-punched carpets and tiles and upholstery fabrics the appearance of these products is more pleasant than that of uncrimped fibres owing to the absence of gloss and they have a bulkier, softer handle. Continuous crimped yams could be suitable for certain types of stretch fabrics or knitted products but so far these products have not reached the commercial stage. Attempts to use the bicomponent fibres for tufted carpets have not been satisfactory so far for two reasons. One reason is that the resilience of the piles is less than that of wool or nylon. Another reason is that fibrillated fibres may show a tendency towards a further fibrillation under severe wear or abuse. [Pg.451]

Very thin fibres for nonwovens can be produced by split fibre technology. Bicomponent fibres are processed into a nonwoven fabric and this is followed by a splitting process. The fibres may be split mechanically by water jet technology or by the chemical dissolution of one component which leaves fine fibres of the other component (Fig. 2.7). [Pg.32]

For the triplication in medical products, tte PVDF is spun by a melt spinning process. In addition to multi- and numofilament also bicomponent fibres can be produced. Multifilaments are subject of currendy carried out studies at the ITA. [Pg.342]

The use of bicomponent fibres, in which each individual fibre is made up of two types of polymer, lying either side by side or in a sheath-core formation, may be regarded as... [Pg.34]

Bicomponent fibres are made from two polymers distributed over the entire length of the fibre by coextruding two components into one single fibre. Various configurations are produced and sold commercially some common examples are shown in Fig. 4.4. [Pg.119]

Alcantara was invented by the Toray Group in 1970. It is based on islands in the sea bicomponent fibres of around 60% polyester and 40% polyurethane (PU), which are then cut into staple fibres and have the sea components dissolved out, before being needle-punched and dyed. [Pg.257]

Thermal bonded air-laid nonwovens are widely used as an interior absorbent core material in feminine hygiene materials, incontinence, and baby diapers (Danweb, 2006). Thermal bonded technology uses PE/PP core/sheath bicomponent fibre (about 30—40% in air-laid) as bond fibre to stick pulp (Xuan, 2006). [Pg.477]

Mitsubishi Rayon Co. has reported the development of heat-storage and electrically conductive acrylic fibres with electrical conductivity > 10 S/cm and clothes for winter clothing and sportswear. These bicomponent fibres comprise a core-sheath structure, a core of P(AN/MA/Sod. methaUyl sulphonate) containing 15-70vol% white electrical conductive ceramic particles (e.g. W-P) and P (acrylonitrile/vinyl acetate) as a sheath. [Pg.62]
