It is twisted on themselves on the D1 of direction.
(it refers to tool, and there are three types of the twists or more according to statement " cord at least three kinds twists " by those skilled in the art
It is a variety of) it will be immediately appreciated by, it is therefore desirable at least three continuous reverse lay operations (or twisting in the opposite direction) are to the present invention
Cord " destructing " simultaneously " return to " initial yarn for manufacturing it, that is, (multifilament is fine for the original yarn for returning in its original state
Dimension), i.e., no twist.In addition illustrate, there are the continuous twisting operations of at least three (three or more) to form curtain of the invention
Line, rather than under normal conditions two.
Another essential feature is that at least half for forming the yarn of cord must have initial bullet greater than 800cN/tex
Property modulus Mi (thus significantly excluding nylon fiber), otherwise observes that bursting force and toughness do not increase.
It will be described in the structure of textile cord of the invention now and be related to the step of manufacturing textile cord of the invention.
Firstly, Fig. 1 schematically shows that the conventional multi-filament textiles fiber (5) under original state (i.e. no twist) (is also claimed
For " yarn ") cross section；It is well known that this yarn is formed by multiple (usually tens to several hundred) unit silks (50),
With usually less than 25 μm of very thin diameter.
On direction D1 (S or Z) after twisting operation T1 (first twist), initial yarn (5) is converted on themselves
The yarn of twisting, referred to as " secondary stock " (10).In the secondary stock, thus unit silk makes itself axis (or secondary stock around fiber
Axis) be deformed into spiral shape.
Then, as shown in the embodiment of fig. 2, then by M stocks, (such as they are 3 herein；10a,10b,10c)
Twist them together with formation " stock " (20) on direction D1 as before with intermediate twist T2 (second twist).Often
A secondary stock is characterized in that, specific first twist T1 (for example, being herein T1a, T1b, T1c), first twist of each stock
T1 can be identical (in general, that is, here, for example, T1a=T1b=T1c) or different from each other.
Finally, indicate to meaning as shown in Figure 3, then by N number of stock (such as being herein three personal shares, 20a, 20b, 20c)
Twist them together on the direction D2 opposite with D1 with final twist T3 (the third twist), it is according to the present invention to be formed
Final textile cord (30).Every personal share is characterized in that specific second twist T2 (for example, being herein T2a, T2b, T2c), often
Second twist T2 of personal share can identical (in general, that is, here, for example, T2a=T2b=T2c) or each other not
Together.
Thus to obtain final textile cord (30) comprising N is multiplied by M (herein, for example, 9) a secondary stock, therefore finally knit
Object cord (30) is characterized in that (at least) three kinds of twists (T1, T2, T3).
The case where present invention is clearly applicable for more than 3 kinds of continuous twists, for example, by four (T1, T2, T3, T4) or five (T1,
T2, T3, T4, T5) twist is planted applied to original yarn (5).Notably, however for cost reasons, the present invention is preferably carried out
Only three continuous twisting operations (T1, T2, T3).
Compared with Fig. 3, Fig. 4 display prepares the usual manner of double twist textile cords.It will be actually directly as the M of stock
Secondary stock (for example, being herein 3 personal share 10a, 10b, 10c) is twisted on (second) direction D2 opposite with (first) twist direction D1
Together directly to form the double twist (T1, T2) textile cords (40) according to prior art.
Fig. 5 schematically shows, in cross-section, the components of 4 personal shares (20a, 20b, 20c, 20d) (in advance with T2a, T2b,
T2c, T2d are twisted together on identical direction D1), by the third intertwining operation T3 on the direction D2 opposite with direction D1 come group
To form tool according to the present invention, there are three types of another embodiments of the final cord (50) of the twist (T1, T2, T3) for conjunction.Every personal share
It is characterized in that specific second twist T2 (in the case can be identical or different with another stock for T2a, T2b, T2c, T2d).
As prompt, Fig. 6 is shown, still in cross-section, aforementioned cord (50) another figure more realistic than the diagram of Fig. 5
Show, looked back the following known fact: textile cord (incidentally, no matter whether it is cord according to the present invention) it is transversal
Face is once formation, in the case where minimum stretch, textile cord stock as provided by the multifilament property of pristine fibre (yarn)
The height of (20a, 20b, 20c, 20d) and time stock (10a, 10b, 10c) laterally radial plasticity and be actually closer to having
The cylindrical structure of the cross section of substantially circular profile.
In this application, " fabric " or " textile material " broadly mean very much by addition to metal substance (no matter
It is natural materials or synthetic) made from any material, can be converted by any method for transformation appropriate silk thread,
Fiber or film.By way of non-limiting example for example, it can be mentioned that polymer spin processes, for example, it is melt spinning, wet
Formula spinning or gel spinning.
Although the material as made from non-polymer material (such as minerals such as glass or non-polymeric organic materials such as carbon)
