Description

CA Application Blakes Ref.: 11578/00001 1 Multilayer Lining Fabric with Improved Properties and 2 Clothes Comprising Same 4 The present invention relates to a multilayer lining fabric having improved properties in respect of elasticity and stretchability. Moreover, the present invention relates to a multilayer 6 lining fabric which improves safety features of the fabric. In a further embodiment, the invention 7 relates to clothes, in particular working clothes, comprising a multilayer lining fabric.
8 Lining fabrics, in particular for clothes used in a specific area as, for example, clothes 9 worn in sports or clothes worn in a working environment, are requested to meet certain requirements concerning the wearer's comfort: Due to the fact that such clothes often need to 11 protect the wearer against uncomfortable weather conditions (low temperature, external 12 wetness resulting from snow or rain), they have to comprise an outer layer protecting against 13 such conditions. On the other hand, the physical conditions of sports or working in the open air 14 are characterized by a large extent of body movements (or movements of certain parts of the body only, e. g. the arms, the upper part of the body, the legs and/or the lower part of the body) 16 and, in connection to that, sweating of the body.
17 Both of those may cause discomfort to the wearer of the clothes, if the clothes' outer 18 (protecting) layer is cushioned with an inner lining fabric: One example of such a lining fabric is 19 the warp-knitted fabric available on the market from the company Engtex AB, Mullsjo, Sweden, under the Trade Name "ENGTEX". The lining does allow such easy body movements to a 21 restricted extent, only (or even prevents such movements), due to a lack of elasticity and 22 stretchability of the lining fabric. This is particularly true for linings made of the above warp-23 knitted fabrics, which were placed inside the protecting layer in two or more layers one above 24 the other, conventionally, with the warp directions of one layer parallel to those of each other lining layer.
26 Moreover, sweat produced by the body under sports conditions or working conditions is 27 removed from the wearer's skin in a decelerated manner, only, or not at all. As a result, a wet 28 lining is rubbing against the skin during the body movements, causing, in addition to discomfort 29 to the wearer, irritation of the wearer's skin or even worse conditions like skin inflammations.
One of the specific properties of such lining fabrics placed one above the other in a 31 plurality of layers was that such a multilayer lining fabric could be used as a protective fabric for 32 chainsaw operators: If all layers were positioned parallel to each other (i. e. the warp direction of 33 each layer was parallel to the warp direction of each other layer) and were well attached to each 22603810.2 CA Application Blakes Ref.: 11578/00001 1 other by seams, the resulting multilayer lining fabric could prevent chainsaw operators in their 2 working environment from injuries by their chainsaw. This was due to the fact that, after cutting 3 through the outer protective layer of the operators' working cloth trousers, the threads of the 4 lining layers were drawn into the chainsaw and could stop the chainsaw's operation within a few moments, thereby preventing the operators from being injured by the motor-driven chains of the 6 saw.
7 What, however, remained was the apparent lack of elasticity and stretchability of the 8 lining fabric, which caused a non-acceptable lack of wearing comfort to the wearers of the 9 clothes when worn in a sports or working environment.
Hence, it was an object of the present invention that the elasticity and stretchability of a 11 multilayer lining fabric be enhanced so as to provide more comfort to the wearers provided with 12 clothes including such multilayer lining fabric.
13 Moreover, it was another object of the invention that the humidity transport (resulting 14 from sweating by the wearer) from the wearer's skin to the environment through the multilayer lining fabric be improved, thereby preventing skin irritations or even inflammations from 16 occurring.
17 In addition, it was another object of the invention that the protecting properties of the 18 multilayer lining fabric against chainsaw injuries of a chainsaw operator be improved, thereby 19 making working accidents less probable if working clothes being provided with the multilayer lining fabric of the invention are worn in a chainsaw working environment.
21 Finally, it was another object of the invention that clothes comprising the multilayer lining 22 fabric of the invention be provided, thereby allowing better wearing comfort to the wearer, for 23 example in the case of sports clothes or working clothes and, in particular, working clothes for 24 chainsaw operators and forest workers.
It was surprisingly found in the present invention that the above objects can be achieved 26 altogether by a multilayer lining fabric wherein two or more layers of a warp-knitted fabric are 27 combined to a lining fabric by a stack of said two or more warp-knitted fabric layers, the warp 28 directions of which are twisted, from one layer to the next, by an certain angle. If a stack of such 29 twisted lining fabrics is stitched loosely-fitting, the resulting multilayer lining fabric in a piece of clothing has a largely enhanced elasticity and may stretch during the movements of the clothes' 31 wearer, thereby providing an improved comfort.
32 Moreover, it was found that working clothes comprising the multilayer lining fabric of the 33 invention present a surprisingly better protection against chainsaw injuries due to a better 22603810.2 CA Application Blakes Ref.: 11578/00001 1 blocking behavior of the chainsaw by the threads of the multilayer lining fabric: The chainsaw is, 2 better than by prior art linings, stopped by the multilayer lining fabric of the invention not only in 3 cases of chainsaw cuts perpendicular to the axis of the trouser legs, but also in cases of 4 chainsaw cuts in a direction diagonal to the axis of the trouser legs:
The European and National standards of the Personal Protective Equipment (PPE) requirements and of DIN
(EN) 381-2 and 6 -5 are met by the multilayer lining fabric and clothes of the present invention, and diagonal cuts 7 standardizing newly developed tests for the twisted direction linings of the present invention are 8 under evaluation.
9 Hence, the present invention relates to a multilayer lining fabric comprising at least two warp-knitted fabric layers of at least one polymer thread material having a weight of 100 g/m2 11 (per layer of material) wherein the number of weft threads is larger than the number of warp 12 threads, wherein, in the plane of the layers of the fabric, the direction of warp threads of one 13 layer is twisted with respect to the direction of warp threads of an adjacent layer by an angle a 14 of at least 20 .

12 Preferred, but exemplary (and non-restricting) embodiments of the present invention, i.
13 e. of the multilayer lining fabric and of the clothes of the present invention, are now explained in 14 detail by referring to the Figures.
The term "comprise", "comprises" or "comprising" as used in the present specification 16 and claims, for example in claim 1 (multilayer lining fabric claim) or in the description of the 17 fabric, is defined to have the meaning that said fabric of the invention may comprise (or include) 18 (i) at least one component of the fabric following said term "comprise"
or "comprises" or 19 "comprising" or may comprise (or include) (ii) two or more components of the fabric following said term "comprise" or "comprises" or "comprising", or that (iii) further components (more 21 specifically defined below) may also be comprised by the fabric of the invention. The same is 22 applicable also to the clothes claims and description of the clothes of the present invention, 23 mutatis mutandis.
24 The term "comprise", "comprises" or "comprising" as used in the present specification and claims is, however, also defined for the present invention to optionally include cases where 26 the multilayer lining fabric of the invention mainly (or even exclusively) consists of (i) at least one 27 component of the fabric following said term "comprise" or "comprises" or "comprising" or mainly 28 (or even exclusively) consists of (ii) two or more components of the fabric following said term 29 "comprise" or "comprises" or "comprising", optionally together with any necessary component a skilled person may optionally additionally include into such a fabric in order to achieve the object 31 of the invention, or may even include cases where the component of the fabric following said 32 term "comprise" or "comprises" or "comprising" exclusively consists of (i) at least one 33 component named or exclusively consists of (ii) two or more components named, optionally 22603810.2 CA Application Blakes Ref.: 11578/00001 1 together with any necessary component a skilled person may include into such a fabric in order 2 to achieve the object of the invention. The same is applicable also to the clothes claims and 3 description of the clothes of the present invention, mutatis mutandis.
4 In other words: The term "comprise" or "comprises" or "comprising" may have, in the present specification and claims, the meanings of describing, or claiming, an exhaustive or, 6 alternatively, a non-exhaustive enumeration of elements, without that, in the former case, 7 embodiments are excluded which, for example in sub-claims of the present application and 8 corresponding parts of the specification, claim (and describe) further features, which are 9 beneficial or advantageous but not essential for the present invention.
The present invention relates to a multilayer lining fabric. The term "lining fabric", as 11 used in the present specification and claims, is defined to mean a textile material made in the 12 form of a plurality of layers each of which consists of textile material threads. Such thread 13 layers, in the case of the present invention, are manufactured by a process of warp-knitting. As 14 is generally known in this technical field, the process of warp-knitting is a knitting method in which the thread zigzags along the length of the fabric and, hence, follows adjacent columns of 16 knitting, i. e. a knitting direction which follows the length direction of the knitted textile material.
17 In an exemplary manner, this is shown in Figure 1, wherein the arrow shows the direction of the 18 warp thread. Such a textile material or fabric is used as a lining under a surface layer or as a 19 protective fabric layer (e. g. of a piece of clothing) in order to generate an underlayer having specific properties.
21 In accordance with the present invention, the lining fabric is a multilayer lining fabric, i. e.
22 has a number of layers of at least two: In accordance with the invention, at least two warp-23 knitted fabric layers of a polymeric thread material are comprised.
24 The number of layers is not restricted to "two" and may comprise, in preferred embodiments of the invention, 2, 3, 4, 5, 6, 7, 8 or 9 or even more warp-knitted fabric layers.
26 There is, in the frame of the present invention, no restriction to the number of the layers of the 27 multilayer lining fabric. An exception is the fact that a larger number of layers increases the 28 overall weight of the multilayer lining fabric of the invention, the latter being in contrast to the 29 object of providing a multilayer lining fabric enhancing the wearing comfort for the wearer of the fabric or of the clothes comprising said fabric, because the fabric's weight increase makes 31 movements in the wearer's sports or working environment more cumbersome.
A number of 32 layers of 5 is preferred, and even more preferred is a number of 6, 7, 8 or 9 warp-knitted fabric 33 layers.

22603810.2 CA Application Blakes Ref.: 11578/00001 1 The polymeric thread material may be one polymeric thread material which is identical in 2 all layers of the multilayer lining fabric or may be two or more polymeric thread materials in 3 different layers of the multilayer lining fabric. A skilled person may select such one (or two or 4 even more) polymeric thread materials from a large number of materials, which are known in the art per se, in accordance with the specific requirements of each single case.
In accordance with 6 the invention, one single polymeric thread material for all layers of the multilayer lining fabric of 7 the invention is preferred; this does, however, not restrict the invention to this preferred 8 embodiment.

9 In accordance with the invention, the material of the (at least two) warp-knitted fabric layers is a polymer thread material. Polymers for threads which may be employed for knitting 11 the warp-knitted fabric layers of the present invention are well-known to a skilled person and 12 may be selected from a large number of polymer materials in accordance with the requirements 13 of a specific case, subject to the parameters of the material. One of those parameters is, 14 naturally, that the polymer must be capable of being made into threads which are suitable for the machine knitting process. Another criterion is the requirement that the material, in the form 16 of a thread, must be capable of being knitted into a fabric material by a warp-knitting process.
17 In accordance with the invention, the polymer material, after being warp-knitted into a 18 fabric layer has a weight of > 100 g/m2. Polymer material fabrics having a weight of > 100 g/m2 19 may be warp-knitted into light-weight lining fabrics having good mechanical properties, as for example excellent stretchability, light weight and good humidity-dissipating properties.
21 Basically there is no upper limit of the fabrics' polymer material weight, with the 22 exception of requesting that, in view of the object to provide a light-weight material promoting 23 the wearer's comfort, the material should not be of a too high weight.
In preferred embodiments 24 of the invention, which may be realized alone or in combination with one or several other features of the invention and which should not be construed to restrict the invention, the 26 materials used in each fabric layer have a weight in the range of from 120 to 180 g/m2, 27 preferably in a range of from 140 to 160 g/m2, more preferably in a range of 160 5 g/m2.
28 Exemplary (but not restricting) weights of the polymer material after being warp-knitted into a 29 fabric layer are 132 g/m2 or 162 g/m2 or 114 g/m2 or 148 g/m2 or 171 g/m2, and such specific weights may be used in combination with others, while having advantageous properties for the 31 invention. Materials having the afore-mentioned weight were found to be particularly suitable for 32 the multilayer lining fabric of the present invention.

22603810.2 CA Application Blakes Ref.: 11578/00001 1 In preferred embodiments of the invention, which may be realized alone or in 2 combination with one or several other features of the invention and which should not be 3 construed to restrict the invention, the materials have a thickness in the range of from 0.4 to 1.0 4 mm, preferably within a range of from 0.6 to 0.8 mm, more preferably within a range of from 0.65 to 0.75 mm, most preferably about 0.7 mm. Materials having the afore-mentioned 6 thickness were found to be particularly suitable for the multilayer lining fabric of the present 7 invention.
8 In preferred embodiments of the invention, which may be realized alone or in 9 combination with one or several other features of the invention and which should not be construed to restrict the invention, the polymer thread material is a polyester or polyamide.
11 Polyesters are particularly preferred materials, since they result into multilayer lining fabrics 12 convenient for the wearer and presenting, in addition, good safety properties, as will be shown 13 below in detail. A skilled person is familiar with polyesters and polyamides, particularly with 14 polyesters, as polymer thread materials known in the present field of the art and may select such polyesters from a large group thereof in accordance with the requirements of a specific 16 case. More preferably, the polymer thread material may be poly (ethylene terephthalate) (PET).
17 One specific material available on the market has turned out to be a particularly suitable 18 material, which material is available from the Company Engtex AB, Mullsjo, Sweden, under the 19 Trade Name "ENGTEX Dyneema".
In accordance with the invention, the warp-knitting of the fabric layers was made 21 resulting into a number of weft threads per centimeter of length of the fabric layers which is 22 larger than the number of warp threads per centimeter of width of the fabric layers, which 23 number ratio represents the density of knitting of the fabric layer material.
24 In preferred embodiments of the invention, which may be realized alone or in combination with one or several other features of the invention and which should not be 26 construed to restrict the invention, in each layer the number of warp threads is 4.5 0.5 27 threads/cm and/or wherein the number of weft threads is 6.5 0.5 threads/cm. Fabric layers of 28 a polymer thread material having been warp-knitted on warp-knitting machines into fabrics 29 having thread densities in the above ranges show particularly good improvements of their properties.
31 In accordance with the present invention, the multilayer lining fabric comprises at least 32 two warp-knitted fabric layers of at least one polymer thread material, which layers are 33 superimposed one on another, and the number of warp-knitted fabric layers may be 2, 3, 4, 5, 6, 22603810.2 CA Application Blakes Ref.: 11578/00001 1 7, 8 or 9 or even more warp-knitted fabric layers, as mentioned above. In preferred 2 embodiments of the invention, 2, 3, 4, 5, 6, 7, 8 or 9 or even more warp-knitted fabric layers, are 3 superimposed on one another, and even more preferable is a number of 6, 7, 8 or 9 warp-4 knitted fabric layers, for example 7, 8 or 9 warp-knitted fabric layers, and most preferable 9 warp-knitted fabric layers which are superimposed on one another.
6 In preferred embodiments of the invention, which may be realized alone or in 7 combination with one or several other features of the invention and which should not be 8 construed to restrict the invention, the direction of warp threads of one layer, in the plane of the 9 layers of the fabric, is twisted, with respect to the direction of warp threads of an adjacent layer, by an angle a of at least 20 . In other words: If two layers of a warp-knitted polymer thread 11 material are formed into a stack of two thread material layers, they are not stacked one upon 12 another in parallel (i.e. with parallel warp thread directions, as in the prior art) but are stacked in 13 a twisted manner so that their warp thread directions are positioned at an angle a to each other 14 of at least 20 .
This is, for example, shown in Figure 2: Two thread material layers 1, 2, each 16 manufactured by warp-knitting are shown side by side in Figure 2 A, and they are shown in 17 Figure 2 B in a superimposed arrangement and twisted, with respect to their warp thread 18 directions (represented by darker lines), by an angle a of, for example, 80 .
19 The technical effect of the feature of a superimposed arrangement of the at least two (and preferably ?. 2) warp-knitted thread material layers twisted by an angle a of at least 20 21 with respect to their directions of the warp threads is twofold: From a safety point of view, the 22 blocking of the operation of a chainsaw cutting into the cloth provided with the multilayer lining 23 fabric in a (for example) vertical or diagonal direction (of trouser legs) is in a short time range 24 comparable to, or even better than, corresponding values of prior art clothes, but the elasticity and stretchability of the multilayer lining fabric (comprising said warp-knitted thread material 26 layers) is enhanced considerably. Even in multilayer lining fabrics having more than the 27 minimum two warp-knitted thread material layers (e. g. 5 or 6, 7, 8, 9 or more, for example 7, 8 28 or 9 warp-knitted thread material layers), the comfort for the user (particularly due to the still 29 enhanced elasticity and stretchability) is remarkable. A motion of the legs under heavy working duty and, hence, including a lot of sweating of the wearer in trousers provided with the 31 multilayer lining fabric is achievable without the appearance of irritations on the wearer's skin.
32 In addition, if a multilayer lining fabric of the above type, as it is in accordance with the 33 present invention, is fixed in trousers of chainsaw operators, and the trousers are subjected to 22603810.2 CA Application Blakes Ref.: 11578/00001 1 the standardized chainsaw cutting tests in the directions perpendicular and parallel to the 2 trousers' legs (so-called PPE test (or in German: EU PSA-Baumuster-Prafung)), the multilayer 3 lining fabric is capable of blocking the chainsaw's operation better than in cases of prior art 4 trousers provided with lining layers superimposed in parallel, with respect to their twisted directions of warp threads of the plurality of layers. Details are described below in the 6 experimental section.
7 In preferred embodiments of the invention, which may be realized alone or in 8 combination with one or several other features of the invention and which should not be 9 construed to restrict the invention, the angle a of twist of the direction of warp threads of one layer with respect to the direction of warp threads of an adjacent layer, is at most 120 0. If this 11 upper limit value of the twist angle a is observed, the elasticity and stretchability of the multilayer 12 lining fabric is also still enhanced. In multilayer lining fabrics having more than the minimum two 13 warp-knitted thread material layers (e. g. having, for example, 6, 7 or 8 layers of the polymer 14 thread material), the comfort for the user (particularly due to the enhanced elasticity and stretchability) is even better. A motion of the legs under heavy working duty and, hence, 16 including a lot of sweating of the wearer in trousers provided with the multilayer lining fabric is 17 achievable without the appearance of irritations or even inflammations on the wearer's skin.
18 Moreover, the standard tests of these multilayer lining fabrics retaining their twist of the 19 directions of their warp threads below the above upper limit value resulted in a better blocking of the chainsaw's operation by the threads of the multilayer lining fabric.
21 In more preferred embodiments of the invention, which may be realized alone or in 22 combination with one or several other features of the invention and which should not be 23 construed to restrict the invention, the angle a of a twist of the direction of warp threads of one 24 layer with respect to the direction of warp threads of an adjacent layer, is within a range of 50 a 110 . It is even more preferable in accordance with the present invention that the angle a 26 of a twist of the direction of warp threads of one layer with respect to the direction of warp 27 threads of an adjacent layer, is within a range of 60 0 a 5 100 . By retaining the twist angle in 28 the above preferred ranges, the above properties of wearing comfort and chainsaw operation 29 safety blocking could be further improved, compared to the prior art.
In further more preferred embodiments of the invention, which may be realized alone or 31 in combination with one or several other features of the invention and which should not be 32 construed to restrict the invention, the angle a of a twist of the direction of warp threads of one 33 layer with respect to the direction of warp threads of an adjacent layer, is within a range of 70 22603810.2 CA Application Blakes Ref.: 11578/00001 1 s a _s 90 . In mostly preferred embodiments, the angle a of twist of the direction of warp threads 2 of one layer with respect to the direction of warp threads of an adjacent layer is within a range of 3 80 5 . Particularly in the latter case, the elasticity and stretchability of the multilayer lining 4 fabric is enhanced to a surprising extent. In multilayer lining fabrics having more than the minimum two warp-knitted thread material layers (e. g. having, for example, 6, 7, 8 or 9 layers of 6 the polymer thread material), the comfort for the user (particularly due to the enhanced elasticity 7 and stretchability) is excellent, compared to the prior art. A motion of the legs under heavy 8 working duty and, hence, including heavy sweating of the wearer in trousers provided with the 9 multilayer lining fabric is achievable without that irritations or even inflammations on the wearer's skin could be observed.
11 Moreover, the standard tests of these multilayer lining fabrics retaining their twist of the 12 directions of their warp threads in the range of 80 5 resulted in a blocking of the chainsaw's 13 operation by the threads of the multilayer lining fabric even exceeding the values obtained with 14 prior art multilayer lining fabrics having a relatively parallel arrangement of their directions of the warp threads.
16 In further preferred embodiments of the invention, which may be realized alone or in 17 combination with one or several other features of the invention and which should not be 18 construed to restrict the invention, directions of warp threads of certain layers of the multilayer 19 lining fabric M, with respect to the direction of warp threads of one of the lining layers as a reference layer, are twisted by angles a, a', a" which are different from each other or which are 21 identical to each other. In other words: In superimposed arrangements of more than two (for 22 example five) thread material layers, all twist angles a, a', a", a"
(etc.) of directions of the warp 23 threads of one layer, relative to the respective superimposed adjacent layer, are different from 24 each other. The respective differences may be different in the absolute value of the angle (i. e.
lal) or may also (or instead only) be different in view of the clockwise or counterclockwise 26 directions. As an alternative, all warp thread direction angles a of different layers are identical to 27 each other.
28 Figures 3 shows an example for the above first case where directions of warp threads of 29 certain layers of the multilayer lining fabric M, with respect to the direction of warp threads of one of the lining layers as a reference layer, are twisted by angles a, a', a"
which are different 31 from each other: In accordance with Figure 3, the angles a of the twist of the direction of warp 32 threads change from one layer couple (layers 1 --> 2) of thread material to the next couple of 33 layers, i. e. adjacent, layers 2 -4 3 layers 3 -4 4, of thread material in their absolute values (e. g.
22603810.2 CA Application Bakes Ref.: 11578/00001 1 a = 40 0; a' = 80 0; a = 60 ). In another preferred embodiment of the invention (described below 2 with respect to Figure 4), the twist angles a of another arrangement are identical in their 3 (absolute) values, but are varied with respect to the clockwise and counterclockwise directions 4 (e. g. a = + 80 0; a' = - 80 0; a" = + 80 ). The above values are exemplary examples only and do not restrict the invention.
6 In further preferred embodiments of the invention, which may be realized alone or in 7 combination with one or several other features of the invention and which should not be 8 construed to restrict the invention, directions of warp threads of two directly adjacent layers, with 9 respect to the direction of warp threads of one of the lining layers as a reference layer, are twisted by the identical angle a (i. e. lal is always the same), while directions of warp threads of 11 the following two adjacent layers are parallel to those of the reference layer, and the angles a 12 are different "only" in their clockwise or counterclockwise directions.
13 This case is shown in Figure 4: The reference layer of the multilayer lining fabric M has 14 the reference numeral 1; its direction of the warp threads is represented by a darker line. The directly adjacent layer 2 of the multilayer lining fabric M has a direction of its warp threads (also 16 represented by a darker line) which is twisted, with respect to the reference layer's (1) warp 17 thread direction, by the angle a, e. g. by 80 5 . The layer 3 directly adjacent to layer 2 of the 18 multilayer lining fabric M has a direction of its warp threads (also represented by a darker line) 19 which is twisted by an angle a identical to the angle a between layers 1 and 2 in its value, but having a counter-clockwise direction, e. g. ¨ 80 5 . The same is applicable to layer 4 21 directly adjacent to the above layer 3 of the multilayer lining fabric M; and so forth. In other 22 words: In the preferred embodiment of the multilayer lining fabric shown in Figure 4, the layers 23 having an odd number (e. g. 3, 5, etc.) each have directions of their warp threads (represented 24 by darker lines) which are parallel to the reference layer's (1) warp thread direction, while the layers having an even number (e. 2, 4, 6 etc.) have directions of their warp threads (represented 26 by darker lines) which are in an angle a of, for example 80 0 5 0, to the warp thread directions 27 of the odd-numbered layers (1, 3, 5 etc.).
28 In the latter case, a kind of "zig-zag" arrangement of the respective adjacent layers' 29 relative twist angle a of their relative directions of the warp thread is established. Such an arrangement is highly advantageous, because the elasticity and stretchability of the multilayer 31 lining fabric is maintained at an enhanced level, to a surprising extent. In multilayer lining fabrics 32 having, for example, 6, 7, 8 or 9 layers of the polymer thread material, the comfort for the user 33 (particularly due to the enhanced elasticity and stretchability) is excellent, compared to the prior 22603810.2 CA Application Blakes Ref.: 11578/00001 1 art. A motion of the legs under heavy working duty and, hence, including heavy sweating by the 2 wearer in trousers provided with the multilayer lining fabric is achievable without that irritations 3 or even inflammations on the wearer's skin could be observed.
4 Moreover, the standard tests (according to the technical standard EN /
DIN 381-2 and 381-5 for chainsaw trousers) of these multilayer lining fabrics retaining their twist of the 6 directions of their warp threads in the range of 80 2 and having the above "zig-zag"
7 configuration of their angles a of the warp thread directions, relative to the warp thread 8 directions of the reference layer of the multilayer lining fabric, resulted in a blocking of the 9 chainsaw's operation by the threads of the multilayer lining fabric which even exceeds the values obtained with prior art multilayer lining fabrics having a relatively parallel arrangement of 11 their directions of the warp threads, in the chainsaw cuts in a direction perpendicular to the 12 trouser leg axis and even more in the direction parallel to the trouser leg axis.
13 Further preferred embodiments of the invention, which may be realized alone or in 14 combination with one or several other features of the invention and which should not be construed to restrict the invention are directed to multilayer lining fabrics according to the 16 invention, wherein 2, 3, 4, 5, 6, 7, 8 or 9 layers are in an arrangement one on top of the other 17 with their directions of warp threads of adjacent fabric layers twisted by an angle a of at least 20 18 and preferably at most 120 and more preferably within a range of 50 a 5 110 0; and are 19 fixed together loosely to form a stack of loosely fixed, e. g. loosely stitched, twisted layers.
Such a fixation of the lining fabric layers, preferably such stitching thereof, may be 21 effected preferably at the edges of these lining fabric layers, so as to form a loosely connected, 22 flexible stack thereof. Hence, in accordance with these preferred embodiments of the invention, 23 such stacks of a plurality of loosely connected/fixed fabric layers are designed to form, and 24 practically form, flexible and stretchable "pillows" comprising such a plurality of the warp-knitted material layers, wherein the relative position of the layers is not tightly fixed, but only loosely and 26 flexibly connected. Thereby, a substantial contribution to the desired flexibility of the lining fabric 27 can be made.
28 The preferred way of loose fixation known to a skilled person is seaming by loosely 29 stitching, although the invention is not restricted to this type of loose fixation.
In a further preferred embodiment of the invention, which may be realized alone or in 31 combination with one or several other features of the invention and which should not be 32 construed to restrict the invention, such a stack of loosely fixed, e.
g. loosely stitched, twisted 33 layers of the lining fabric material may be included into a textile pad, and such a pad comprises 22603810.2 CA Application Blakes Ref.: 11578/00001 1 a surrounding envelope and an inner stack of 2, 3, 4, 5, 6, 7, 8 or 9 loosely fixed, e. g. loosely 2 stitched, fabric layers in an arrangement one on top of the other with their directions of warp 3 threads of adjacent fabric layers twisted by an angle a of at least 20 O.
4 The textile pad is defined, for the present specification and claims, to be a textile material in a sheet form and capable of forming the envelope needed for surrounding the fabric 6 layer stack, capable of maintaining said envelope shape under the conditions of use of the pad, 7 and capable of being fixed, by textile fixation processes as, for example, stitching, to other 8 textile sheet materials. The material of which the pad is formed may be any material a skilled 9 person knows for the desired purpose of surrounding the plurality of loosely fixed or loosely stitched fabric layers, and such a material may be selected by a skilled person from a number of 11 suitable materials according to the parameters which must be observed.
12 In further preferred embodiments of the invention, which may be realized alone or in 13 combination with one or several other features of the invention and which should not be 14 construed to restrict the invention, the textile material of the pad envelope is selected from knitted or woven textile materials, which ¨ in more preferred embodiments ¨
will have to have, 16 or to retain, a high elasticity. Polymer materials like polyamides and ¨
even more preferred ¨
17 polyesters are preferred materials. Polyesters are even more preferred, because they retain 18 their elasticity, are "skin-friendly", i. e. do not undergo any changes in their mechanical 19 properties and are capable of being treated with a "wicking" finish material capable of wicking sweat away from the skin. Particularly preferred materials are those materials known under the 21 commercial names ELASTANR or LYCRAR.
22 The resulting pad comprises or includes said stack of a plurality of lining fabric layers the 23 directions of the warp threads of which are twisted by a certain angle a as explained above, and 24 loosely connected to a stack of textile layers, preferably by loosely stitching said layers, preferably at their edges.
26 Such a pad, in accordance with the invention, is required to be capable of being fixed, by 27 any conceivable textile fixation process, to another textile material, for example to a textile 28 material forming a piece of clothing, of which a cloth (e. g. a trouser) for sports purposes of for 29 working purposes are two examples, only. A suitable textile fixation process may be selected by a person skilled in this field in accordance with the requirements needed.
Such a fixation 31 process may be a step of stitching the pad to a sheet of a textile material, preferably by machine 32 stitching the borderline or the edges of the pad to said sheet of textile material.

22603810.2 CA Application Blakes Ref.: 11578/00001 1 As a result, the sheet of textile material comprises the pad fixed (e.g.
stitched, preferably 2 machine-stitched) to the sheet, and its position on the sheet is clearly defined. On the other 3 hand, the pad itself comprises included, and loosely connected, the flexible stack of lining textile 4 layers, which stack, inside the envelope, provides the desired stretchability, resulting into the wearer's comfort.
6 In another aspect, the invention relates to clothes which comprise at least one multilayer 7 lining fabric according to the present invention as described above in detail, as well as a shell 8 layer. Such a shell layer may be a layer directed to the outer side of the clothes and may 9 additionally have certain functions as, for example, a water repelling function, a safety signal colour, without restricting the invention to those functions.
11 Hence, with respect to the clothes of the invention, the above description of the 12 multilayer lining fabric of the present invention can be referred to in all details, and all features of 13 the multilayer lining fabric of the invention, i. e. one feature of the above-described features 14 alone or several or all features of the above-described features in combination, as well as its/their objects and advantages, are also applicable to the clothes comprising such multilayer 16 lining fabric.
17 The clothes of the invention may comprise at least one of the multilayer lining fabrics of 18 the invention or may comprise two or three or even more of the multilayer lining fabrics. In a 19 preferred embodiment of the invention, which may be realized alone or in combination with one or several other features of the invention and which should not be construed to restrict the 21 invention, the clothes of the invention comprise one multilayer lining fabric of the above-22 described invention, in addition to the shell layer.
23 In a further preferred embodiment of the invention, which may be realized alone or in 24 combination with one or several other features of the invention and which should not be construed to restrict the invention, the clothes of the invention comprise the multilayer lining 26 fabric according to the invention (one multilayer lining fabric or two or even three or more 27 multilayer lining fabrics, preferably one multilayer lining fabric) in only a part thereof. This means 28 that the clothes comprise parts where no multilayer lining fabric of the invention is applied. One 29 of the reasons is that the purposes of said multilayer lining fabric (in particular the safety feature of being capable of blocking a chainsaw operation cutting into said cloth) are needed to be met 31 only in parts of the cloth.
32 In a further preferred embodiment of the invention, which may be realized alone or in 33 combination with one or several other features of the invention and which should not be 22603810.2 CA Application Blakes Ref.: 11578/00001 1 construed to restrict the invention, the clothes of the invention comprising the multilayer lining 2 fabric are selected from sports clothes and working clothes. In these preferred types of clothes, 3 the advantages of the invention, particularly the advantages afforded by the multilayer lining 4 fabric, can ideally be achieved: Both clothes are worn by people who have to move their bodies very much, which fact is closely connected to sweating. Hence, these wearers need clothes 6 adapted to multi-movement types of activities and, hence, must be comfortable in their wearing 7 properties, e. g. must provide elasticity and stretchability.
8 In addition, in the case of working clothes, safety aspects have to be observed. As a 9 specific feature, the clothes of the invention, equipped with the multilayer lining fabrics of the invention, allow a blocking capability for chainsaws which surprisingly exceeds similar properties 11 as tested in standard procedures described below in the experimental part of this description.
12 In a further preferred embodiment of the invention, which may be realized alone or in 13 combination with one or several other features of the invention and which should not be 14 construed to restrict the invention, the clothes are chainsaw protection clothes, preferably for forest workers, which surprisingly exceed all expectations not only with respect to the wearing 16 comfort, but also with respect to the safety aspect: In chainsaw cut tests according to the EU
17 standard EN 381-2 and 381-5, the clothes according to the invention and comprising the 18 multilayer lining fabric of the invention achieved very good results:
The preferred clothes of the 19 invention, working trousers for forest workers, achieved good, in part even considerably better test results (more rapid stopping of the chainsaw's operation by the threads of the lining fabric 21 layers) not only in chainsaw cuts perpendicular to the trouser leg axis, but also in chainsaw cuts 22 in a direction diagonal to the trouser leg axis). Details thereof are described below in the 23 experimental part of the description.
24 In particularly preferred embodiments of the invention, which may be realized alone or in combination with one or several other features of the invention and which should not be 26 construed to restrict the invention, the clothes of the present invention comprise the multilayer 27 lining fabric according to the above-described preferred embodiments of the multilayer lining 28 fabric of the invention, wherein the loosely stitched stack of twisted layers or the textile pad of 29 the surrounding envelope and the inner stack of 2, 3, 4, 5, 6, 7, 8 or 9 loosely fixed, preferably loosely stitched (for example along their edges) fabric layers in an arrangement one on top of 31 the other with their directions of warp threads of adjacent fabric layers twisted by an angle a of 32 at least 20 0, and preferably at most 120 and more preferably within a range of 50 5 a 5 110 33 , is separately stitched to the inner side of the clothes' shell layer, without additionally 22603810.2 CA Application Blakes Ref.: 11578/00001 1 stitchingly fixing the twisted layers to the clothes' shell layer. As mentioned above, such 2 multilayer lining fabric according to the invention may be applied to the whole inner side of the 3 clothes' shell layer or may be applied only to a part thereof.
4 The shell layer may be of any suitable material a skilled person knows for purposes of sports clothes, working clothes etc. and, hence, may be selected from any suitable material in 6 accordance with the specific requirements of a single case. Typical examples of a material 7 selected as the shell layer material is a material selected from materials having a sufficient 8 stability, weather resistance, wicking properties and tear strength, which is essential for sports 9 clothes and working clothes. A skilled person knows such materials for shell layers of sports and working clothes and, hence, may select such materials in accordance with the requirements of a 11 specific case. Particularly preferred materials re polyam ides and polyesters, and polyesters are 12 even better preferred. Exemplary (albeit not restricting) materials are those known under the 13 commercial names ELASTAN A and LYCRA R.
14 In a further preferred embodiment of the invention, which may be realized alone or in combination with one or several other features of the invention and which should not be 16 construed to restrict the invention, the clothes of the present invention comprise advantageous 17 and, hence, preferred embodiments, wherein a plurality of layers of the multilayer lining fabric of 18 the above detailed description is arranged one on top of the other with their directions of warp 19 threads of adjacent fabric layers twisted by an angle a of at least 20 and preferably at most 120 and more preferably within a range of 50 a 5 110 ; wherein such arrangement of said 21 plurality of layers is symmetrical to a manufacturing direction of the clothes' shell layer. Said 22 clothes' manufacturing direction may be the lengthwise direction of knitting or weaving (i. e. the 23 warp thread direction). In other preferred embodiments, such arrangement of said plurality of 24 layers is symmetrical to a longitudinal axis of parts of said clothes extending in a longitudinal direction, e. g. to the longitudinal axis of the trousers' legs. In other words: The plurality of layers 26 is arranged, with respect to the manufacturing direction or longitudinal axis direction in such a 27 manner that angle a's half angle (= a/2) is located exactly on the working direction or 28 longitudinal trouser leg axis, thereby achieving that the elasticity of the overall material (i. e.
29 multilayer lining fabric with its plurality of layers plus shell layer) is retained on a high level, while achieving good safety standards in working clothes' safety tests (particularly the diagonal cut of 31 the chainsaw safety test; see the experimental section below).
32 In a further preferred embodiment of the invention, which may be realized alone or in 33 combination with one or several other features of the invention and which should not be 22603810.2 CA Application Bakes Ref.: 11578/00001 1 construed to restrict the invention, the clothes of the invention comprising the multilayer lining 2 fabric of the invention (as described above in all details), particularly the working trousers, may 3 additionally comprise an additional knee protection area, affording an additional protection effect 4 to the wearer's body when working on the knees or including movements where a touch to the knee is involved.
6 Such an additional knee protection area may be made in accordance with usual prior art 7 knee protection means, but, in accordance with the invention, is preferably made of an 8 imprintable cushioning material applied to the knee area of the trouser lag or even to both knee 9 protection areas of both trouser legs. Such protective cushioning may be made of any material a skilled person is aware of for the desired purposes.
11 However, in a further preferred embodiment of the invention, which may be realized 12 alone or in combination with one or several other features of the invention and which should not 13 be construed to restrict the invention, the clothes of the invention comprising the multilayer lining 14 fabric additionally comprise an additional knee protection area to which is applied, directly onto the shell material, an imprintable cushioning material made of an imprintable polymer material, 16 wherein ¨ even more preferably - the polymer may be selected from the group consisting of 17 melt-printable polymers, particularly from polyurethanes. Optionally, the adherence of such a 18 polymer material, preferably the adherence of such a polyurethane material, to the clothes' shell 19 layer is improved by means of the application, on the area between the clothes and the additional knee protection material, of an adherence improver. A skilled person knows such 21 adherence improving materials and may select them in accordance with the nature of the 22 polymer and clothes' materials based on the general skill.
23 The additional imprintable cushioning material may be applied to the outside surface of 24 the cloth, preferably of the working or protection trouser of the invention, in any conceivable shape. In particularly preferred embodiments of the invention, the application may comprise 26 small spot patterns or small line patterns or small picture patterns, which may either have the 27 same appearance (e. g. color) as the fabric sheet on which they are applied or may be different 28 in appearance (e. g. color) so that they are silhouetted against the fabric basis. In the latter 29 case, the manufacturer of the working clothes may show a logo or a safety sign by such an imprinted cushioning material.
31 In the following, the multilayer lining fabric of the present invention, as well as the clothes 32 comprising such a multilayer lining fabric of the invention, are in more detail explained by 33 referring to specific examples. It has to be noted that the examples are given only for allowing a 22603810.2 CA Application Blakes Ref.: 11578/00001 1 better understanding of the invention and should not be construed to limit the invention to the 2 specific examples.

4 Examples Chainsaw operators' trousers subjected to the tests described below comprised an outer 6 water protection fabric made of ELASTAN R and an inner lining consisting of 8 warp-knitted 7 fabric layers and an additional lining fabric made of LYCRA R between layers Nos. 7 and 8 8 (calculated from the inner to the outer side of the lining fabric stack (see Figures 5A to 5D). In 9 each layer, the number of warp threads was 4.5 0.5 threads/cm, and the number of weft threads was 6.5 0.5 threads/cm.
11 The direction of warp threads of warp-knitted fabric layer 2 was twisted, with respect to 12 the direction of warp threads of layer 1, by an angle of + 80 0; the direction of warp threads of 13 warp-knitted fabric layer 3 is twisted, with respect to the direction of warp threads of layer 2, by 14 an angle of -80 0(1. e. is the same as the direction of warp threads of layer 1); the direction of warp threads of warp-knitted fabric layer 4 is twisted, with respect to the direction of warp 16 threads of layer 3, by an angle of + 80 0; the direction of warp threads of warp-knitted fabric 17 layer 5 is twisted, with respect to the direction of warp threads of layer 4, by an angle of -80 , 18 (i. e. is the same as the direction of warp threads of layer 1); etc.
etc.. This arrangement of the 19 layers under the water protection fabric shell layer is shown in Figure 5A, exemplarily.
The eight layers shown in Figure 5A were packed into an envelope made of ELASTAN R
21 without stitching them together, and the surrounding envelope was stitched at both ends by 22 sewing; any other stitching method instead of sewing could have been employed.
23 The resulting "textile pad" was applied to the left leg front side of chainsawer's working 24 trousers. The resulting trousers were evaluated by the wearers to provide the desired elasticity and stretchability and did not cause any discomfort even under hard-sweating work conditions.
26 The same trousers were subjected to the EU PPE standard test by cutting on a test 27 stand with a chainsaw cut perpendicular to the trousers' legs' axis and stopped the chainsaw 28 under conditions identical to the usual EU PPE standard test (speed of the chains, cutting 29 angle).
Moreover, the same trousers are being subjected to a modified test under the Industrial 31 Standard EN 381-2 and 381-5. This standard has a test stand which is being modified for the 32 multilayer lining fabrics due to their twisting of the warp directions in the plane of the multilayer 33 fabric layers. First results (to be confirmed in further tests) showed that the chainsaw chain 22603810.2 CA Application Blakes Ref.: 11578/00001 1 stopping by entangling the chain with the warp threads is better than the conventional multilayer 2 fabrics having parallel directions of their warp threads, thereby surprisingly showing a better fit 3 into safety requirements for such type of clothes, in addition to better wearing comfort for the 4 wearers.
Working trousers made for chainsaw workers of the above materials were subjected to a 6 4 week longtime field test under relatively high temperature (autumn) and high humidity (rain) 7 conditions and were found by the workers to be better adapted to the requirements and more 8 convenient to wear under high load sweating conditions (mountain forest) than all other 9 materials available on the market: Particularly the desired elasticity and sweat-dissipating properties were found to be outstanding.
11 The invention was described above in detail while referring to its preferred embodiments.
12 The reference to the preferred embodiments should, however, not be understood as a limitation 13 of the invention. Quite to the contrary: The scope of the invention is only determined by the 14 claims which follow.
