Description

本明細書では、「織物のフィラメント」という表現は、それらの構造、長さ、強度および弾性のために、製織および／または樹脂仕上げプロセスによって、布地に変換されおよび／または複合材料を製造するために加工されるトウまたはヤーンの製造のために繊維産業で使用される粘り強く柔軟な糸を紡糸により互いに薄く結合する能力を有する繊維製品のセットを定義することを意図している。
As used herein, the term "woven filaments" is used to convert to fabrics and / or to produce composites by weaving and / or resin finishing processes due to their structure, length, strength and elasticity. It is intended to define a set of textile products capable of thinly binding to each other by spinning the tenacious and flexible yarns used in the textile industry for the production of tows or yarns processed into.

Claims

It is a method of stretching the tow of a non-braided filament of a woven fabric, and the above method is
A cross section traversing the principal direction extending along its own principal direction (A) and having a predetermined width (W1, W2, W3) and a predetermined thickness (s1, s2, s3) of at least 1 cm. A step of providing a toe (F) of a non-braided filament of a woven fabric, wherein the non-braided filaments of the woven fabric are arranged side by side and are not mechanically / structurally bonded to each other.
The step of supplying the toe (F) along the movement path (P), and
The tow (F) is stretched to define the spread toe (ST1, ST2) in order to increase the predetermined width (W1, W2, W3) and decrease the predetermined thickness (s1, s2 , s3 ). Including steps to do
The step of extending the toe (F) is
By immersing the tow (F) of the non-braided filament of the woven fabric in the bath (6),
A series of transverse waves (8a, 8b) that traverse the tow (F) laterally with respect to the principal direction (A) to translate and arrange the individual filaments side by side are generated in the bus (6). By doing so, the toe (F) is permanently extended, and
Including extracting the spread tow (ST1, ST2) from the bus (6).
The tow (F) entering the bus (6) and / or the spread tow (ST1, ST2) extracted from the bus (6) were not sized and were not sized.
The step of generating the series of transverse waves (8a, 8b) is
Supplying the toe (F) along the movement path (P) on the support (10) having a plurality of through holes (11).
Generating a first wave (8a) by feeding a liquid exiting the plurality of through holes (11) along the first direction (D1).
A method comprising producing a second wave (8b) by sucking up liquid that enters the plurality of through holes (11) along a second direction opposite to the first direction (D1) .

The method of claim 1, wherein the step of generating the series of transverse waves (8a, 8b) is performed by stirring the bath (6) in the vicinity of the toe (F).

The steps that generate the series of transverse waves (8a, 8b) alternately traverse the tow (F) in the first direction (D1) with the series of first waves (8a) and the first. The two directions (D2) include producing a series of the second waves (8b) across the toe (F), both of which are the first and second directions (D2). The method according to claim 1 or 2, wherein F) is lateral to the principal direction (A) and the predetermined widths (W1, W2, W3).

The step of generating the series of transverse waves (8a, 8b) comprises supplying the tow (F) along the travel path (P) by partially winding it on a rotating drum (12). The method according to any one of claims 1 to 3 , wherein the drum is provided with a plurality of through holes (11) on its outer surface.

The generation of the first wave (8a) and the second wave (8b) causes the lobeed roller (14) to rotate inside the drum (12) at a rotation speed different from that of the drum (12). 4. The method of claim 4 .

Any of claims 1-5 , comprising a plurality of said stretching steps performed in succession, each stretching step comprising immersion in a bath (6) and generation of a series of transverse waves (8a, 8b). Or the method described in paragraph 1.

The step of supplying the toe (F) comprises providing a coil (2) composed of said tow of a non-braided filament of a woven fabric wound around a winding shaft, the step of unwinding the coil (2). The method according to any one of claims 1 to 6 , which is carried out by the above.

The method according to any one of claims 1 to 7 , comprising the step of drying the spread tow (ST1, ST2) after the stretching step.

The method according to any one of claims 1 to 8 , comprising the step of winding the spreading toe (ST1, ST2) to provide the spreading coil (C).

9. The method of claim 9 , comprising binding the spread tow (ST1, ST2) to the material of the sheet or film (16), which is operably performed prior to the winding step.

From claim 1, the toe (F) entering the bus (6) is not sized and the method comprises a step of sizing the toe (F) at the same time as or thereafter at the stretching step. The method according to any one of 10 .

11. The method of claim 11 , wherein the bath (6) is defined by an aqueous liquid containing a sizing agent to perform the sizing step of the tow (F) at the same time as the stretching step.
