    • Fibrillation of certain cellulosic fibres has been widely studied, and fibrillation can be utilised to improve fabric performance, for example strength, absorbency, surface area together with handle and opacity. However, it believed that keratinous fibres such as wool have not been treated in this way. The invention seeks to provide a fibrillated keratinous fibre fabric and a method of fibrillating natural fibres. A textile fabric of keratinous fibre is disclosed characterised by the presence of fibrils, micro-fibrils and proto-fibrils. The fibrils may be further characterised as having diameters in the range 3 mum to 5 mum and by having lengths in the range 25 mum to 60 mum. Preferably, the fabric is a woven, knitted, non-woven or composite fabric. A method of treating natural fibres is also disclosed which comprises:- a pre-treatment to remove surface lipid materials or scales, e.g. using an oxidising agent; a treatment to remove or partially remove intercellular cement, e.g. using an enzyme; and the application of mechanical agitation under aqueous conditions, e.g. hydroentanglement, to complete fibrillation.
    • 已经广泛研究某些纤维素纤维的纤维颤动,并且可以利用纤维颤动来改善织物性能,例如强度,吸收性,表面积以及手感和不透明度。 然而,它认为如羊毛这样的角质纤维没有被这样处理过。 本发明寻求提供原纤化角质纤维织物和使天然纤维原纤化的方法。 公开了一种角质纤维的织物,其特征在于原纤维,微原纤维和原纤维的存在。 原纤维可进一步表征为直径在3μm至5μm的范围内,长度在25μm至60μm的范围内。 优选地,织物是机织,针织,非织造或复合织物。 还公开了一种治疗天然纤维的方法,其包括: - 去除表面脂质材料或鳞屑的预处理,例如, 使用氧化剂; 去除或部分去除细胞间水泥的处理,例如, 使用酶; 并且在水性条件下施加机械搅拌,例如。 水刺,完成纤维颤动。

    • A method for upgrading existing nylon fibers comprising the steps of (a) impregnating the existing nylon fibers with a chemical for obtaining impregnated nylon fibers; (b) drawing the impregnated nylon fibers for obtaining drawn nylon fibers; and (c) drying the drawn nylon fibers for obtaining upgraded nylon fibers. An upgraded nylon fiber, derived from an existing nylon fiber by the method. A nylon fiber reinforced hardened cementitious composite comprising a hardened cementitious matrix, the cementitious matrix including staples of textile or non-textile (technical) upgraded nylon fibers. In both cases the fibers are preferably upgraded using the method. A method for manufacturing a nylon fiber reinforced hardened cementitious composite. The method comprising the steps of (a) preparing a mix including a cementitious material, staples of upgraded nylon fibers and/or textile nylon fibers and an activating material (e.g., water) for activating said cementitious material to form a hardened cementitious matrix; (b) placing the mix; and (c) allowing the mix to harden.
