The invention relates to a method of manufacturing a polyolefin multifilament yarn comprising twisting a partially drawn multifilament yarn and post-twist-drawing the twisted partially drawn multifilament yarn.

The process comprises the following stages: making the rope of fabric pass through a nozzle (9) located within a hermetically sealable washing vessel (1), and then joining the start and the end of the fabric to form it into a closed loop; supplying to the nozzle (9) for a predetermined period a flow of a fluid capable of causing the loop of fabric to rotate and a flow of a liquid solvent capable of wetting the fabric and of dissolving the dirt thereon; at the end of the washing period, interrupting the flow of solvent, extracting from the vessel (1) the liquid solvent contained in it and the solvent vapours from the circulating air; and then interrupting the supply of the said driving fluid to the nozzle (9) and extracting the washed fabric from the vessel.

The invention provides an apparatus for processing wool and a corresponding solvent process utilizing the apparatus. The apparatus includes an inlet (2) for the admission of raw (greasy) wool, and a first bowl (3) to which wool is first admitted. Wool in first bowl (3) is wet, as by solvent spray from nozzle (11) and falls into a solvent bath (13). An endless belt (5) transports wool through solvent bath (13) in bowl (3). A co-flow of solvent through nozzle (14) is utilized to ensure that wool disposed on belt (5) travels at the same speed as the belt (5). A pressurized spray from shower device (7) is directed to wool on belt (5) to cleanse same. Wool treated in first bowl (3) is carried on an elevated portion of belt (5) where it is subjected to a cascade of solvent from weir (8). Wool is carried out of bowl (3) into bowl (4) by falling from the upper extremity of belt (5) in the vicinity of roller (17). This wool is then carried by endless belt (6) for a second cleansing treatment. Co-flow of solvent is introduced into bowl (4) through nozzle (15). A shower of solvent is provided through shower device (9). Endless belt (6) has an elevated portion between rollers (18) and (19). Wool carried on this elevated portion of belt (6) is treated to a cascade of pure solvent from weir (10). Wool is carried from bowl (4) to a centrifuge for drying.

The present invention relates to a process and a device for chlorine-free shrinkproof treatment of a wool raw material and an article thereof. In particular, the process of the present invention comprises the steps of a chlorine-free shrinkproof treatment, washing with water, protease inactivation, a softening treatment, dehydration, drying and the like, wherein a chlorine-free catalysis system consisting of a protease, a specific organic phosphine compound and the like is selected, removing the scale layer on the surface of wool fibres cooperatively and efficiently and modifying the scale layer so as to improve the shrinkproof performance of wool articles. The process of the present invention can completely replace the chloridisation shrinkproof method in the prior art, and is not only environmentally friendly, but also has low requirements for equipment, can be operated continuously and is suitable for large-scale industrial production.

The present invention relates to a system for injecting a functional solution for fabric and a method for manufacturing fabric using same. The system includes: a first supply portion; a second supply portion provided with a distributing device; an injection portion provided with a needle; a drying portion provided with a hot air blower or a blower; and a collection portion provided with a collecting roll. An injection method is provided in which the needle on the injection portion, installed so as to be moved reciprocally, is directly inserted into the fabric to inject the functional solution, so that the functional solution is absorbed from the outer surface to the inside of the fabric.

The woven fabric (1) according to the invention comprises warp (2) and weft (3, 4) yarns, the weft yarns (3, 4) comprise first weft yarns (3) and second weft yarns (4), the first weft yarns (3) and the warp yarns (2) form a base layer (1a) of the fabric, while the at least one plurality of second weft yarns (4) forms an additional layer (1b) of the fabric that can be broken under a stress without damaging the base layer (1a) to change the appearance of the fabric (1) and of the clothing articles made of said fabric (1).

The process comprises the following stages: making the rope of fabric pass through a nozzle (9) located within a hermetically sealable washing vessel (1), and then joining the start and the end of the fabric to form it into a closed loop; supplying to the nozzle (9) for a predetermined period a flow of a fluid capable of causing the loop of fabric to rotate and a flow of a liquid solvent capable of wetting the fabric and of dissolving the dirt thereon; at the end of the washing period, interrupting the flow of solvent, extracting from the vessel (1) the liquid solvent contained in it and the solvent vapours from the circulating air; and then interrupting the supply of the said driving fluid to the nozzle (9) and extracting the washed fabric from the vessel.

L'invention concerne un procédé et une installation comprenant au moins:

• - un poste dit «d'enduction» (B), constitué par une enceinte (2) destinée à contenir la suspension du polymère (8) et comprenant un dispositif d'admission en continu (A) des fibres (1) de façon unidirectionnelle, un moyen (10) pour séparer ces fibres en leurs filaments unitaires pendant la traversée de la suspension et un moyen (9c) pour rassembler ces filaments à la sortie de cette suspension; un poste (C) dit «de séchage» des fibres chargées de polymère; un poste (D) dit de «traitement thermique» pour amener le polymère à l'état fondu ou pâteux et un poste (26-27) dit «de formage» ou de «préformage».
