The present invention refers to a method for continuous production of a textile structure resistant to perforation and penetration, comprising the steps consisting in:

a) simultaneously weaving two fabric elements overlapped and spaced from each other, wherein at least the warp or chain threads of the upper fabric element and the weft threads of the lower fabric element, or vice-versa, comprise ballistic threads;

b) inserting, during said weaving step, at least one intermediate layer between said upper fabric element and

said lower fabric element;

c) joining the assembly of the two upper and lower fabric elements interposed between which is said intermediate layer to obtain a multilayer textile structure.

A method for manufacturing a three-dimensional fabric and a three-dimensional fabric using the same are provided. The method includes the steps of: selecting at least more than one yarn (32, 31) among nylon6, nylon66 and a super high tenacity yarn (33) to be used as a warp yarn and a filling yarn; weaving the selected warp and filling yarns to produce a basis fabric with ripstops (34); inserting the basis fabric into a dyer and dyeing the basis fabric by providing a predetermined concentration of a dye at a predetermined temperature for a predetermined period, so that a special pattern and a color are expressed on the basis fabric because of a difference in density, material characteristic and thermal transformation temperature between the warp yarn and the filling yarn; and drying the dyed basis fabric for a predetermined period at room temperature to make the ripstops (34), the pattern and the color clear without deformation.

Ce métier comporte perpendiculairement à un bâti longitudinal (2), un support (3) portant un dévidoir (5) d'un cordon d'âme (6), un touret rotatif portant des bobineaux (9) de cordons retors (10) pour les franges, des moyens (13) renvoyant les faisceaux de cordons (6, 10) parallèlement à la direction longitudinale de déplacement de deux nappes (17) de fils de chaîne, métier dans lequel un crochet (19) à mouvement alternatif vient saisir l'un des cordons retors (10) s'enroulant autour de l'âme (6) pour le faire passer entre les deux nappes (17) et former une frange (22), avant d'aller saisir un autre cordon.

Selon l'invention, la tige du crochet frangeur (19) est montée avec possibilité de débrayage par rapport à ses moyens d'entraînement (32) et comporte, à son extrémité opposée à celle du crochet (19), un talon (33a) apte à venir, en fin de course de frangeage, en appui sur au moins l'une des faces de butées (34a, 34b) d'un organe (35) déplaçable séquentiellement pour modifier la course du crochet en rapport avec la forme de l'ondulation devant être donnée aux franges.

A rotary cage (104) arranged above for applying warp spools and driving them to unroll their yarns and for compensating the length differences between the lengths of warp yarns delivered and the ones entrained comprises warp spools (43) arranged in two levels. A stationary device positioned underneath for rearranging the warp yarns from a preceding circular distribution to a subsequent planar two-plane distribution thereof is composed of two intake rollers (21) and two lateral shutter masks (22) arranged below. An assembly positioned underneath for creating a warp-yarn Z-system and a warp-yarn S-system, respectively, is composed of two spirally wound shafts (23). A shed-forming assembly positioned below is composed of a cam spindle (24) incorporated under a respective spirally wound shaft (23). A weft laying-in and beating-up, respectively, attachment positioned underneath consists of a weft shaft (25). Alternatively, a shed-forming weft-laying-in and weft-beating-up, respectively, weft shaft (25') positioned below is incorporated under a respective spirally wound shaft (23).

A multi-axial fabric constructed by a triaxial fabric including oblique warp yarns (α,α') of different direction which are interwoven in weft yarns (Y) and straight warp yarns (β,β') interwoven with the weft yarns (Y) constructing the triaxial fabric. At all of the locations where the oblique warp yarns (α,α') are crossed with each other, the oblique warp yarns (α,α') and the weft yarns (Y) are interwoven with each other, and the straight warp yarns (β,β') are interwoven with the weft yarns (Y) which are interwoven with the oblique warp yarns (α,α').

A weaving machine is provided, having opposite arrays of first heddles (3) which are subjected to an alternate weft-wise movement. The weaving machine is also provided with opposite arrays of second heddles (32) which arranged on one side of the respective arrays of the first heddles (3) adjacent the cloth fell (FL).

The present invention provides a tetraaxial woven fabric in a novel texture exhibiting isotropic nature superior to that of the triaxial woven fabric and is composed of warp ends, weft ends, and intersecting upper and lower bias yarns running obliquely to the former two under such circumstances as increasing demand for triaxial woven fabrics having isotropic nature in strength and elongation requisite to improve­ment in strength and reduction of weight of FRP and supply of materials suited to the manufacture of air­crafts and autocars. Further, for the purpose of weaving and tetraaxial fabric as above, the present invention provides a bias yarn feeding device and bias yarn traversing device in a structure that has never been devised before, thereby enabling high speed weav­ing and production at low cost of a fabric exhibiting high isotropic characteristics in spite of reduced thickness thereof.

Seersucker weaving method and a seersucker loom capable of carrying out the seersucker weaving method. When the puckering warp yarns (6) are divided to form a shed (5) in weaving a seersucker by the seersucker weaving method, the tension of the puckering warp yarns is maintained on a level below that of the tension of the ground warp yarns (2), and the puckering warp yarns are slackened positively at least during a slackening period from shed closing operation to beating-up operation for every turn of the main shaft (3) of the seersucker loom so that the tension thereof is reduced below a predetermined tension of the same during a period other than the slackening period to slacken portions of the puckering warp yarns near the cloth fell (5) sufficiently during beating-up operation in order that the puckering warp yarns can be puckered satisfactorily.
