摘要： A method of manufacture of a nonwoven cellulose fabric is disclosed. The fabric is made from fibres formed by extrusion of a solution of cellulose through a spinning jet. The extruded fibre is attenuated with a high velocity gas flow, and the attenuated fibre is collected on a surface (such as the curved surface of a rotating drum) on which the fibre web is subsequently coagulated. Apparatus for carrying out the method is also disclosed. The method and apparatus permit the manufacture of a nonwoven lyocell fabric web in which fibres are bonded together without the use of a binder.

摘要： Garments are constructed from lyocell fabric which has been resignated using a textile resin having just two groups per molecule which can reactively cross-link with cellulose molecules of the lyocell fabric then causticised by application under tension of an aqueous solution of sodium hydroxide, and the constructed garments are dyed in a garment dyeing operation. Garments can be produced by this route which retain a smooth, evently-dyed appearance with unpuckered seams and minimal creasing and so present a desired formal look, as distinct from the casual look imparted by the effects of fibrillation normally produced when lyocell garments undergo garment dyeing.

摘要： A method of manufacture of a nonwoven cellulose fabric involves the fibres being formed by extruding a solution of cellulose through at least one spinning jet and subjecting the extrudate fibre to a high velocity gas flow. The fibre passes through a vapour mist which at least partially coagulates the fibre prior to collection as a fibre web. By use of such method, a fabric having a high loft and a relatively low density may be obtained.

摘要： A method for the manufacture of lyocell fibre includes the steps of: (i) forming a solution of cellulose in an aqueous tertiary amine N-oxide solvent at a temperature above ambient temperature, the solution having from a trace (as herein defined) to 30 percent by weight of particles of a thermoplastic polymer having a glass transition temperature below the temperature at which the solution is formed, based on the weight of cellulose dispersed therein; ii) extruding the solution by way of a die into an aqueous coagulating bath, thereby forming lyocell fibre; iii) washing the fibre to remove residual amine N-oxide therefrom, and drying the fibre; and (iv) crimping the fibre so as to induce from 2.5 to 8 crimps/cm in the fibre. In the method according to the invention, the thermoplastic polymer is preferably dispersed throughout the lyocell in domains, and the maximum dimension of substantially all of the domains is preferably no more than 50 nanometres (nm). The invention provides lyocell fibre having a trace to 30 percent by weight of low melting thermoplastic polymer and 2.5 to 8 crimps per centimetre.

摘要： A method for dyeing and finishing a lyocell fabric or polynosic fabric includes the steps of dyeing the fabric with a reactive dyestuff under conditions such that primary fibrils are formed; removing the primary fibrils from the fabric by treatment with a solution of a cellulase; heating the solution to both denature the cellulase and induce secondary fibrillation; and drying the fabric. The method offers the advantages of low liquor usage and shortp rocessing time.

摘要： A garment having recoverable stretch properties is made from a fabric woven from warp and/or weft yarns of normally inelastic lyocell yarns which have a crimped configuration which is set-in and which imparts a stretch in the warp and/or weft direction of the fabric of at least 15 per cent with a stretch recovery of at least 90 per cent. An uncreased garment having such recoverable stretch properties is produced by holding the garment in an unconstrained and uncreased condition, for example by suspending it from a hanger, and immersing it successively in a bath of swelling agent such as sodium hydroxide solution to develop the crimp and then in a wash bath to set the crimp. An arrangement of creasescan be set into such a garment by trying it into a bundle before the swelling and crimp-setting steps, and this procedure may also be applied to a garment knitted from normally inelastic lyocell yarns.

摘要： A process for the preparation of cellulosic shaped bodies is provided in which a solution of cellulose in a tertiary amine N-oxide and, optionally, water is shaped in the hot state and the shaped solution is cooled with a gaseous medium prior to being introduced into a coagulation bath, the gaseous medium flowing through the shaped solution from a gas inlet side to a gas outlet side. The process is characterised in that the gaseous medium is removed by suction on the gas outlet side in a direction substantially parallel to or substantially opposite to the direction of movement of the shaped solution.

摘要： A process for producing a dyed and finished lyocell fabric having a clean, soft-touch finish by carrying out the steps of dyeing, washing and drying a lyocell fabric using vigorous action such as by jet dyeing or rotary tumbling on the fabric in at least one of the steps so as to produce fibrillation on the surface of the fabric, is characterised in that, before the dyeing step is carried out, the fabric is evenly impregnated with an aqueous solution of an acid or acid donor and is then heat treated in a gaseous atmosphere to activate the action of the acid or acid donor. The dyed and finished fabric has a clean, soft-touch finish substantially free from visible crease marks normally produced on lyocell fabrics which have been subjected to vigorous action in dyeing and/or finishing.
