EP2664701A1 - Method for producing a knitted fabric with at least one float thread and fabric obtained therefrom - Google Patents

Abstract

The method involves forming a single-surface basic knit (11) in which the float threads (12) are inserted, in the row of stitches. The float threads on the first side knit fabric are transferred with a thread guide to a starting position, to be visible on the second side knit fabric. The stitches are transferred corresponding to the desired width of the second knitted fabric on the visible side float thread portion. The back slopes of stitches are transferred to the original needles and the basic knit stitch rows are formed. An independent claim is included for a knitted fabric.

Description

Fleece threads are usually used in technical crochets to influence the cross-elasticity of the knitted fabric in some areas or in the entire knitted fabric. In medical knitted fabrics, a floss thread is often used as a so-called weft thread, which has different properties and strengths than the thread of the basic knit. These weft threads are always horizontal and are guided within a double-sided knit and held by this.

Furthermore, floats in knitted garments are known, which are used as a design element. In single-ply knit fabrics, the flossing threads are secured in the fabric by forming stitches or tufts, which requires that the strength of the tufting be approximately equal to the fineness of the machine for processing by the needles of the knitting machine.

The present invention has for its object to provide a method with which it is possible to produce a single-surface knit fabric with floss threads, in which the floss threads can vary significantly in strength from the strength of the thread of the basic knit.

1. a) Bilden eines einflächigen Grundgestricks bis zu der Maschenreihe, in der der Flottfaden eingelegt werden soll;
2. b) Bringen des Flottfadens auf der ersten Gestrickseite mit Hilfe eines Fadenführers in eine Startposition, ab der der Flottfaden auf der zweiten Gestrickseite sichtbar sein soll;
3. c) Umhängen von Maschen in einer Anzahl, die der gewünschten Breite des auf der zweiten Gestrickseite sichtbaren Flottfadenbereichs entspricht, beginnend an der Startposition des Flottfadens;
4. d) Legen des Flottfadens über die umgehängten Maschen mit Hilfe des Fadenführers;
5. e) Zurückhängen der umgehängten Maschen auf ihre Ursprungsnadeln;
6. f) Bilden von Maschenreihen des Grundgestricks in einer beliebigen Anzahl.

The object is achieved by a method for producing a knitted fabric with at least one floss thread on a flat knitting machine with at least two needle beds, which is characterized by the steps:

1. a) forming a single-surface base knit up to the course in which the floss thread is to be inserted;
2. b) Bringing the floss thread on the first fabric side by means of a thread guide in a starting position, from which the floss thread should be visible on the second fabric side;
3. c) transferring stitches in a number corresponding to the desired width of the tuft area visible on the second fabric side, starting at the start position of the tuft;
4. d) Laying the floss thread over the stitched stitches with the help of the thread guide;
5. e) hanging back the stitched stitches on their original needles;
6. f) forming courses of the basic knit in any number.

With the method according to the invention, the floss thread is therefore held solely by clamping between meshes of the base knit in this. There is no formation of tongs or stitches with the floss thread. Therefore, the floss thread can be distinguished in particular by its strength clearly from the thread with which the basic knit is formed. The method according to the invention therefore opens up new design possibilities in particular.

The Fleckfadenführer is preferably designed as Intarsia Faderiführer. However, it can also be used normal thread guides that can be spent with the help of thread guide shifts in their effective ranges. In addition, the use of self-propelled yarn guides is possible.

In a preferred embodiment of the method, steps b) to e) are repeated at least once after step f). The floss thread is thus brought on the first fabric side to a new starting position, from which it should be visible on the second fabric side, and then creates another Flottfadenbereich on the second fabric side. This results in different Flottfadenbereiche in which the Flottfaden is visible either on the first fabric side or on the second fabric side. In this case, the floss thread in step b) from the thread guide in the same direction or in the opposite direction as in the previous step d) are moved. If it is moved back by the thread guide, then arise on the fabric sides several superimposed Flottfadenbereiche. By moving in the same direction, a plurality of towpath areas are created side by side in a horizontal direction. By varying the length of the fleece in the horizontal direction and the number of courses of the basic knit in step f), the angle at which the floss thread can the first fabric side runs, be changed. There are thus also Flottfadenverläufe different from the horizontal direction possible.

Of course, several floats can be inserted at different points of the basic knit. These floats can also be inserted according to the method so that they at least partially intersect. The intersection can take place at the point of passage of the floss threads from one knit side to the other knit side and / or on one or both sides of the knit fabric.

In a further variant of the method, the basic knit can be formed from two partial knits which are knitted adjacent to one another, and the two pieces with at least one floss thread by hanging stitches in the edge region of both knitted parts and laying the floss thread over the looped stitches at a plurality of superimposed Positions of the knitted parts are joined together. In this embodiment of the method, the two parts are sewn together, as it were, by the fleece thread, which runs alternately on the front and on the back of the knitted parts in the edge region thereof. Of course, several floats can be used for this process.

The at least one floss thread may have a different thickness and / or a different material than the thread of the base knit. For example, even fine leather strips can be used as a floss thread. For technical textiles, the use of wire-like materials for the pile thread is also possible.

The floss thread can also be a bundle of threads, which can be achieved further optical effects. Thus, for example, a plurality of threads of different colors can be inserted as a colored fleece bundle bundle by the method in the knitted fabric.

The invention also relates to a knit fabric which is produced by a method according to the invention and which is characterized in that it comprises at least one visible on the front and / or back floss thread, which is held by clamping between stitches of the knitted fabric.

The knitted fabric can preferably have a single-surface basic knit. The at least one floss thread can run in the fabric to form an angle between 0 ° and 90 ° with the courses of the knitted fabric. Furthermore, the at least one floss thread may have a different thickness, a different material and / or a different color than the one or more threads of the basic knit.

Various embodiments of knitted fabrics according to the invention and the method according to the invention for their production will be described in greater detail below with reference to the drawing.

Fig. 1a shows a knit fabric 10, which consists of a monoseal basic knit 11, which in the example shown is a smooth-right knit. In the base knit 11 a Flottfaden 12 is inserted, which in a certain section in the x direction of the basic knitted fabric 11 and over the entire height of the basic knit 11 on the visible side of the basic knitted fabric 11 in a plurality of superimposed and obliquely extending from bottom left to top right Sections 13 can be seen. The width and the slope of the sections 13 are constant.

Fig. 1b illustrates the production of the knitted fabric 10 from Fig. 1a in principle. In the row R1, stitches 11 are formed on the needles D-M of the front needle bed according to the desired number of courses until the start of the fleece insertion. Furthermore, the floss thread 12 is fed from the right knit edge by means of an intarsia thread guide. Subsequently, the pile yarn 12 in row R2 is moved to its start position S by moving the yarn guide according to the desired width of the pile yarn area between the needles G and H of the front needle bed. Thereafter, in rows R3, the stitches of the needles H, I, J of the basic knit 11 are transferred to the needles h, i, j of the opposite needle bed according to the desired width of the pile thread area. In row R4, the pile yarn 12 is moved in a length corresponding to the number of stitches in row R3 against the feed direction from row R2 over the stitched stitches, before the stitches stitched in row R3 are fed onto their original needles H, I, J of row R5 be hung back front needle bed. Thereafter, not shown in detail re-forming courses for the basic knitted fabric 11, wherein the number of courses determine the height and angle of the portions 13 of the floss 12. Subsequently, repetitions of the Steps of the rows R2 - R5 corresponding to the desired number of sections 13 in the wale longitudinal direction y of the knitted fabric 10.

Fig. 2a shows a knit 20 with a basic knit 21, which is also a smooth-right knit. In the base knit 21 a float 22 is introduced. The visible on the front of the basic knit 21 sections 23.1 - 23.n of the flat thread 22 are provided with the same pitch, but have in the γ direction of the knitted fabric 20 an increasing length, wherein the increase in length on the left side of the sections 23.1. 23.n takes place.

The Fig. 2b - Fig. 2d illustrate the method for producing the knitted fabric 20. In row R1, stitches of the desired number for the base knit 21 are formed with the needles D-M of the front needle bed 21 until the beginning of the fleece thread insert is reached. The pile yarn 22 is fed from the right knitting edge until it has reached its starting point S between the needles I and J of the front needle bed (row R2). Subsequently, in rows R3, the stitches of the needles J, K, L of the front needle bed are transferred to the opposite needles j, k, I of the rear needle bed before the pile yarn is laid from left to right over the stitched stitches in row R4 and in series R5 the stitches looped in row R3 are returned back to their original needles J, K, L. In series R6 several courses are again formed for the basic knit 21. In line R7, the tow 22 is moved by its thread guide in its position between the needles L and M, which it has reached in row R4, to a point of reversal U1 between the needles H and I of the front needle bed. Thereafter, in rows R8, the stitches I-L of the basic knit are transferred to the needles of the back needle bed, and then in row R9 the pile yarn 12 is transferred over the stitched stitches placed opposite to the feed direction from row R7. In row R10, the stitches looped in row R8 are returned to the original needles I-L of the front needle bed. In series R11, courses are again formed for the basic knit 21 on the needles D-M of the front needle bed in the same number as in the row R6. In line R12, the tow 22 is moved from its position between the needles L and M of the front needle bed to a second reversing position U2 between the needles G and H of the front needle bed. Thereafter, in row R13, a total of five stitches are now transferred from the needles H-L of the front needle bed to the associated needles h-I of the rear needle bed. Thereafter, the pile yarn is placed in row R14 over the stitched stitches before being hung back in row R15. These steps are repeated until the desired number of sections 23.n has been reached.

Fig. 3a shows a knitted fabric 30 with a base fabric 31, in which a fleece thread 32 is inserted. The fleece-thread insert is made such that a plurality of obliquely extending sections 33.1 - 33.n can be seen on the visible side of the knitted fabric 30. The sections 33.1-33.n increase in length in the y-direction of the knitted fabric. Unlike the in Fig. 2a shown fabric 20 takes place here but the increase in length on both sides.

The Fig. 3b - Fig. 3d illustrate the manufacture of the fabric 30 in principle. In series R1, courses are formed for the base fabric 31 with the needles D-M of the front needle bed. The tuft 32 is fed from the right until it has reached its starting point S between the needles G and H of the front needle bed in row R2. Subsequently, in rows R3, the stitches of the needles H, I, J of the base knit become the opposite needles h, i, j of the rear needle bed umgehängt. Thereafter, in the direction of movement from left to right, the laying of the floss thread 32 over the looped stitches before they are hung back in row R5 again. In series R6, stitches are again formed for the basic knit 31 on the front needle bed with the needles D-M. In row R7, the movement of the floss thread with the help of its thread guide to the reversal point U1 of the first section 33.1. Beginning at the reversal point U1, ie starting from the needle G, five stitches are finally transferred to the back needle bed and then the pile thread is laid over these stitches in row R9, before the stitched stitches in row R10 are returned to their original needles G - K be hung back front needle bed. In row R11, courses are again made in the same number as in row R6 for the basic knit 31. In row R12, the floppy thread is moved from the position between the needles L, M to its reversing position U2 between the needles E, F before the steps of the rows R3 - R12 are repeated, wherein the fleece thread area is widened on the left and right by one or more needles.

Fig. 4a shows a knit fabric 40 with a basic knit 41 and a floss thread 42, in which case the width of the base knit 41 in the x direction, which is covered by the floss thread 42, remains constant in each case. In the γ direction, however, the visible sections 43.1-43.n of the flat thread 42 vary in their pitch and thus also in their length.

The Fig. 4b and Fig. 4c clarify the basic course of the process for producing a knitted fabric according to Fig. 4a , In row R1, stitches 41 are formed for the basic knit 41 with the needles D - M of the front needle bed until the height position of the insert of the knitting fabric Flottfadenführers 42 is reached, which is moved from the right knitting edge ago to the starting point S (row R2). Subsequently, in rows R3, the stitches of the basic knitted fabric of the needles H-L of the front needle bed corresponding to the desired width of the floss thread 43.1 are transferred to the needles h-1 of the back needle bed. In row R4, the floss thread is guided in a length corresponding to the number of stitches interspersed in row R3 in the opposite direction from the row R2, before the stitches of the needles h-l are again hung back onto the needles H-L in row R5. In row R6, courses are again formed for the basic knit 41 on the needles D-M of the front needle bed. In row R7, the floss thread is moved by its thread guide from its position between the needles L and M of the front needle bed to the left to the reversal position U1 of the floating thread between the needles G and H. Thereafter, the stitches of the basic knit on the needles H-L are again transferred to the opposite needles h of the back needle bed, and then the pile yarn in row R9 is moved from the turning point U1 to the right to between the needles L and M of the front needle bed. Then in row R10, the stitches transferred in row R8 are hung back again. These steps are repeated, in which case different numbers of courses are formed for the base fabric 41 when forming the base fabric in row R6, whereby the different gradients of the sections 43.1-43.n arise.

• In Reihe R1 werden mit den Nadeln D - N Maschenreihen für das Grundgestrick 51 gebildet und der Flottfaden 52 von rechts zugeführt.

In Fig. 5a a knitted fabric 50 is shown, which has a basic knit 51, in which a fleece yarn 52 is likewise inserted. The float thread 52 is here in the various sections 53.1 - 53.n laid in the form of a lying eight around the stitches of the base knit 51, like the Fig. 5b and Fig. 5c illustrate:

• In row R1, stitches for the basic knitted fabric 51 are formed with the needles D-N and the pile yarn 52 is supplied from the right.

Subsequently, in row R2, the knitting of stitches of the basic knit from the needles G, H, I takes place corresponding to the desired width of the left-hand region of the section 53.1 on the needles g, h, i of the opposing needle bed. In row R3, the floss yarn in the fabric is moved between the needles F and the front needle bed by shifting the yarn guide according to the desired width of the pile yarn area. Thereafter, in the course R4, the stitches of the needles g, h, i are hung back on the needles G, H, I and at the same time the stitches of the needles J, K, L are transferred to the back needle bed. Thereafter, in the course R5, the pile yarn is moved in a length corresponding to the number of stitches hung in the row R4 in the opposite direction to the feeding direction of the row R3. Subsequently, in rows R6, the stitches interleaved in row R4 are hung back onto their original needles J, K, L of the front needle bed. These steps are repeated until the desired number of sections 53.n has been reached.
