Apparatus for the individual control of the raising and lowering movement of warp yarns on a fabric weaving loom, in which the warp yarns are passed through guide eyes, these eyes being mounted on the piston rods of fluid pressure operated piston and cylinder jacks. There are a large number of jacks, these being grouped in a plurality of units which are removable and are juxtaposable with respect to number and position in accordance with the desired density of warp threads, the units being arranged in at least two tiers. This gives great flexibility of control.

A Jacquard machine of the type possessing to-and-fro moving lifting wires having arresting hooks for coupling with stationary arresting blades. At least one stationary guide edge is provided at the region of a stationary arresting blade fixing the lower shed position. This guide edge cooperates with a projection located at the neighboring lifting wire moving into the lower shed position, so that the lifting wire is deflected and in the lower shed position is coupled with the associated stationary arresting blade.

In a double-lift jacquard with two superposed movable knife frames and a lower stationary open-shed frame, each of the double hooks comprises a single substantially straight rod-like branch rotatable about its axis; two superposed main beaks each cooperating with one of the movable frames under control of the needle associated with the hook, these main beaks being directed substantially at 90* from each other about the axis of the branch in such manner that when one main beak is caught by a transverse knife of the corresponding movable frame the other main beak is brought by rotation of the hook about the axis of the branch, to an ineffective lateral position at which it cannot be caught by the other movable frame; and a lower open-shed supporting beak adapted to cooperate either with the stationary open-shed frame at the raised position of the hook if same is to remain raised at the next stroke of the loom, or with a transverse bar of a stationary guiding and supporting grid disposed below the openshed frame, the said open-shed supporting beak being directed along the bissectrix of the main beaks about the axis of the branch in such manner that when it supports the hook the main beaks thereof are at 45* to the knives of the movable frames and may be caught by any of them under control of the needle.

Disclosed is a camouflage fabric which simplifies a preparation process of warps and wefts so as to assure convenience in warp and weft preparation and acquires combinations of various patterns and colors using a three-ply fabric structure so as to satisfy aesthetics, i.e., one of functions of clothing, and to have an excellent camouflaging effect. Dyed yarns of a dark color and dyed yarns of a light color are alternately arranged as the warps, dyed yarns of three colors differing from the colors of the warps are used as the wefts, the warps and the wefts are woven into the camouflage fabric of a three-ply jacquard texture using a jacquard loom and, thus, the camouflage fabric may have combinations of various patterns and colors.

A method of manufacturing a one-piece textile by a jacquard machine includes a preparation step, a jacquard weaving step, a textile separation step, and a textile ironing step. A woven cloth is made of the method and includes a base fabric and multiple textiles connected with the base fabric by at least one sewing area. The woven cloth is a one-piece structure made by a jacquard machine. The textiles are separated by trimming the at least one sewing area from the woven cloth. Each textile is a complete product with a one-piece structure without sewing. The manufacturing method can improve the efficiency of textile production.

Disclosed herein are a loom for weaving a fabric with two types of tissue, a shoe upper woven using the loom, and a shoe including such a shoe upper. The loom includes a first heddle stack formed by arranging a plurality of first heddles in one or more rows, and a second heddle stack formed by arranging a plurality of second heddles in one or more rows, the second heddles being different in kind from the first heddles. The first heddle stack and the second heddle stack are sequentially arranged in a warp feeding direction.

A quick drying textile includes a composite fabric layer and a moisture absorbing fabric layer. The composite fabric layer includes a plurality of hydrophobic regions and a plurality of hydrophilic regions. The moisture absorbing fabric layer is combined with the composite fabric layer, whereby moisture is collected in the hydrophilic regions and is absorbed by the moisture absorbing fabric layer for vaporization.

The invention relates to a Jacquard machine, comprising 2 sets of knifes moving up and down in opposition, which each, at each of their extremities, are taken up in separate knife grids (4a, 4b) being driven by a cinematic drive chain (30), and each, at one of their extremities (20a, 20b), being guided into a straight motion by means of a “Watt's linkage” rod system, the height of lift of each of these extremities (20a, 20b) of the knife grids (4a, 4b) being adjustable, and the knife grids (4a, 4b) each at their first extremities (20a, 20b) being linked with at least one first driving lever (2, 2a, 2b, 10) by means of a first linking rod (3a, 3b), and at their second extremities (21a, 21b) being linked with at least a second driving lever (2, 10) by means of a second linking rod (14a, 14b), wherein per knife grid (4a, 4b) one or several elements (1, 101, 1a, 1b, 3a, 3b) of the Watt's linkage rod system are part of the cinematic drive chain (30), and the amplitude of the motion of the said extremity (20a, 20b) of the knife grid (4a, 4b) is adjustable in the cinematic drive chain (30) before the linking point (9a, 9b) between the first rod (1, 101, 1a, 1b) and the third rod (3a, 3b) of the Watt's linkage rod system with respect to the drive motor.

In this mechanism (7) a moving hook comprises a body (20) provided with a nose (202) for bearing against a corresponding knife (14), and a flexible blade (21) secured to the body so as to be capable of moving relative thereto and designed to interact with a retaining lever (16) belonging to the selector device. The selector lever (16) forms a ramp (313) over which a portion (214) of the resilient blade (21) slides when the hook (13) is moved in the vicinity of its top dead-center position. The ramp on which the selector lever slides is shaped in such a manner that the component (FA+FB+FC) parallel to the travel direction (X-X′) of the moving hook (13) of the resultant of the forces (RA, RB, RC) acting on the flexible blade (21) when in contact with the ramp (313) in the vicinity of the top dead-center point of its travel and at the beginning of its downward movement (F14), is directed downwards.
