Description

The invention relates to a monolithic warp knitted fabric with a plastic and openwork pattern in the form of openings between groups of interlocking stitch pillars.

The warp patterns with an openwork pattern, in particular so-called "flight patterns", are characterized by differently arranged or regularly spaced ragged or larger openings in the knitted fabric and arise in knitted locations that lack the interconnection of adjacent stitch pillars. The size of the holes is directly proportional to the number of rows in which the stitch columns were not interconnected. The basic requirement in the design of openwork patterns is to maintain the integrity of the knitted fabric and the purposeful spacing of openings, the shape of which is modified for technical knitted fabrics by other chemical or thermal processes to fix the desired dimensions. From the point of view of the construction of the openwork patterns, it is important to have the selected yarn laying with the thread sleeve in such a way that the thread is laid in each row and on each needle, except when a thread is not permanently placed on a needle. It is known in the art that many types of conventionally manufactured single-strand warp knitted knitted fabrics in a stable embodiment, e.g. mesh or tulle patterns,

- 2 fillet patterns with needle-laying, fur patterns, jacquard fi flight patterns, open-weave constructions with smooth weave and the like.

The present invention seeks to define single-stranded warp knits with a plastic pattern whose construction has been specifically designed to be used in extreme conditions for technical purposes, such as shoe seams, insulating pads or protective clothing, based on the high bulkiness and breathability of pH reduced thermal conductivity.

The delimited debris has been achieved by a single warp knitted fabric whose basic structural element is formed by interconnected groups of stitches, for example in two, three or four-column groups. SUMMARY OF THE INVENTION The groups of these stitch pillars comprise single stitch threads of at least one base assembly and double stitch threads of the base assembly to which the threads of at least one reinforcement assembly are attached, the outermost inner pillars of the wall of apertures being interconnected groups stitches reinforced by double stitches either in all rows or in selected rows, for example in every second row. It is possible to fill groups of stitch pillars with further threads, thus achieving even more stability and fullness of the weave.

The groups of stitch pillars approach each other with their edges on the reverse side of the knitted fabric, which I intensify considerably, especially in the opposite direction of return. The groups of stitch posts exhibit a rectangular, lobed, oval or kidney shape in a cross-section, i.e., in a plane perpendicular to the direction of the stitch posts.

The principle of the invention is evident from a closer explanation of the principle of exemplary design variations of the highly breathable monolithic warp knitted fabric of the invention, wherein FIG.

3-stitch groups of stitches with double stitches in all rows of aperture walls, FIG. 2 of 3-stitch group of stitches with double stitches in every second row of aperture walls, in FIG. a group of stitches, filled with threads of one filling system, with an irregular distribution of double stitches in the walls of the openings.

FIG. 1 shows a highly permeable, single-faced warp knit with a plastic pattern on both sides, the base of which is formed from single stitches χ in groups of three columns interconnected in rows R2, R3, R5, R6, R8, holes are formed at the points of interconnection of the groups & columns above one another. In columns $ 3, S4,

S6, SJtedc in all rows the double eyelets g, which delimit and reinforce the walls of apertures B while at the same time softening the points of interconnection of pillar groups, i.e. below and above apertures B. In this way a distinctive plastic pattern and uniformly stabilized , in the longitudinal direction. In columns S1, S2, S5, S8 in all rows there are simple loops 1 of n1t1 of the base system. Referring to FIG. 2, the base of the knitted fabric consists of single stitches 1 in groups A of three columns which are interconnected in rows R1, R2, R5, R6. The openings B between the pillar groups A arise at the points of interconnection of the pillars & groups one above the other. In the columns JSI, S3, S4, S6, S7, two rows of double loops g are formed which amplify alternately the walls of adjacent offset holes g and strengthen the points of interconnection of groups & columns with each other, ie, below and above holes g. In all rows, single stitches 1 are present. Compared to the weave of FIG. 1, all the holes g are enlarged due to the use of an open chain in the base. The reinforcing threads in the double eyelets g stabilize the knit in all rows and form a plastic pattern on both sides. Fig. 3 shows a single-warp knitted fabric whose base i® is formed from a counter-jersey laying in groups A of three columns of single stitches 1 at the edges of groups A and double stitches X * in the middle of groups A. In rows R1, R2 R 3, R 5, R 6

- 4 the stitches in groups A are tightly locked together, while in rows R4 and R7 the groups are displaced laterally to form holes g. The threads of the reinforcement assembly form irregularly spaced double stitches g with the base system threads, which amplifies the walls of the holes g _of thus přllplvajl increased zobjemněnl groups & · columns S2 and S5 are mainly double stitches g in the remaining columns S1, S3, S4, S5, S7 alternating single primer X with doubled loops g. Referring to Figure 4, the warp knit according to the invention is formed on the basis of single stitches 1 in groups of 4 columns, namely a leotard laying interwoven at the edges of the groups & in the form of a linen cloth. In rows R4 R8, the groups are displaced laterally to form holes g whose walls in rows R1, R2, R3, R5, R6, R7 are reinforced with double stitches g * from the two threads of the reinforcement assembly. The double loops g 'are distributed in the knit substantially substantially every row. In the basic tricot weave, the thread of the padding system is incorporated to strengthen and soften, while improving the physiological properties of this type of knit. It also strengthens and reinforces the upper and lower edges of the holes g.

Example 1

Highly breathable monolithic knitted fabric was made on the MAYER R5N rasping machine gun. 40ER using five laying machines, modeled for combined laying. Four laying machines, 2 «, 3«, 4., 5. with 3: 3 sleeve Full / empty / threads PESh 167 dtex x 1 NR in duplicate and No.1 single-use sleeve 2: 1 / solid / empty / threads POPh 167 dtex x 1 NR. The combination of weave designs, including sleeves and used materials, ensures the following properties of knitted fabric for the needs of the footwear industry, which demands openwork knitted fabrics with reinforced holes walls, high permeability and bulkiness of knitted fabrics, stiffness at low ductility.

Example 2

The highly breathable and bulky single-knitted fabric was made on the warp knitting machine of Example 1 using five combination layers, also pattern-threaded. Two knitting apparatuses, 1 and 3 with a 4: 1 sleeve (solid / empty), were threaded with PESh 167 dtex x 1 NR threads for a reversible offset jersey, and the machine was ". in double sleeve 1: 4 (solid / empty) threaded with PESh 167 dtex x 1 NR and laid a base cloth in the edges of the pattern to soften the walls of the holes and twist them to the reverse side of the knitted fabric. and 5. place only under the needles in a triple sleeve of mixed PES / Ba 165 dtex x 1-50 / 50, which in addition to enhancing the full spots in the knitted fabric, provides improved physiological properties and strengthens the edge of the hole walls. The knitted fabric is particularly suited to the specific requirements of the glass industry for satisfactory transverse and longitudinal stability, especially for work suits.
