Abstract

FIELD: textile; paper.

SUBSTANCE: invention concerns knitted fabric manufacturing technology, particularly manufacturing of tubular single-knit sinker knitted fabric with patterns. Method of knitting single-knit sinker fabric with patterns and arbitrary inclusion of plated loops and tucked loops in the pattern involves plated thread broach through individually selected needles raised above the level of complete needle clearing and forming a pattern, and through individually selected edge hooks raised above needles forming pattern loops and raised by a level higher than incomplete needle clearance for previous loop removal from needle latches. Further binder thread is broached through all needles to form background loops of binder and plated threads at some needles and binder thread loops at the other needles over which edge hooks are holding plated thread tucks which are further transferred to needles forming pattern loops by raising needles by one level above than complete clearing.

EFFECT: extended product range of single-knit sinker knitted fabric with patterns.

Description

The invention relates to the field of knitwear production technology, namely to the production of a single culinary patterned knitwear of a tubular shape.

A known method of knitting a single cooler patterned knitwear, belonging to the class of press knitwear, on machines with reed needles according to the method of forming a sketch without a conclusion, in which the selected needles are raised to the height necessary to obtain a new row of threads. At the same time, the old loop remains on the tongue, therefore, when all the needles are lowered to knit the loops, an old loop and a sketch are located under the hook of the selected needle, which, when subsequently raised to the height of the complete confinement, will be dropped onto a new loop of the next loop, thereby forming a press loop , i.e. loop with a sketch [1] // Marisova OI Knitted patterned weave. - M .: Light and food industry, 1984, p.135, Fig. 11.3a - analogue //.

The disadvantages of this method include the fact that the resulting drafts are discarded simultaneously with the old loops, which leads to a limitation of the number of drafts, and this is undesirable from the point of view of the patterned effect, an increase in the number of drafts on the loop leads to uneven structure, a decrease in elongation and strength of knitwear.

There is also a known method of knitting a single cooler patterned knitwear, which is a flip plated weave, in which platted loops of two threads, tiling and ground, as well as loops of ground yarn with a broach of tiling yarn, are selectively patterned. For this, the needle trajectory is divided during the conclusion, namely: the needles on which the plating and soil threads should be laid rise above the level of the usual conclusion, and the needles, on the backs of which the plating thread should be laid, rise so that old loops come off with reeds [2] // Marisova OI Knitted patterned weave. - M .: Light and food industry, 1984, p. 89, Fig. 6.26 a, b - analogue //.

Its disadvantages include the fact that the known method gives reduced to the needle pitch compared to the length of the thread in the loop length of the broach of the plating thread, leading to a decrease in the elongation and strength of the knit.

The objective of the invention is to provide a method for knitting a single cooler patterned knitwear, providing a technical result, which consists in expanding the range of a single cooler patterned knitwear by developing a knitting process that allows you to get a fairly extensible structure containing selectively background loops from plating and ground threads and loop patterns from ground threads and outline of the thread of the thread.

The specified technical result is achieved due to the fact that in one knitting cycle, loop loops of plating and soil threads are selectively formed on some needles, and loops of a pattern of ground thread and a sketch of plating thread are formed on the other needles, for which they first lay the plating thread on individually selected and raised to a level higher than the full conclusion of the needle, forming a loop of the background, as well as individually selected side hooks extended above the needles, forming a loop of the pattern and going to the level you e incomplete conclusion for the removal of old loops from the tongue of the needles, then the soil thread is laid on all needles and the background loops of soil and plaiting threads are formed on some needles, and soil loops on other needles, over which the side hooks hold the outline of the plaiting thread , and then transfer them to the needles forming the loop of the pattern, when the needles rise to a level above the full conclusion.

An advantage of the proposed method is the fact that the formation and fastening of the press draft from the plating thread is carried out in a row with the skeletons of loops of soil thread, which to a lesser extent limits extensibility and strength compared to known methods, and also to a lesser extent reduces the uniformity of the knitwear produced in comparison with press jersey.

In addition, the advantages of the proposed method for knitting a single cooler patterned knitwear include the possibility of obtaining structures with a pronounced patterned effect, which is a combination of embossed, openwork, tinted effects with color when using a different composition and properties of raw materials.

The inventive method can be carried out on single-cylinder machines of average diameter from 10-16 '', used to produce blanks of seamless linen, with the number of systems - 6-8 and the presence of individual electronic selection of needles and side hooks to form a pattern: two selection nodes in each system.

The proposed solution is illustrated in figures 1-3, where figure 1 shows the trajectory of the needles of the proposed method of knitting, figure 2 - operation of the inventive method of knitting, and figure 3 shows the structure of the produced knitwear.

Figure 1 presents the trajectory of the upper point of the hook of the needles (level 1), as well as the tip of the hook of the needles (level 2), the axis of the tongue (level 3) and the end of the tongue of the needles (level 4) relative to the bump plane (O-O) in one single-cylinder machine system 28 of a needle diameter class of 14 '', with the number of systems - 8 and two nodes for individual selection of needles and side hooks. The threading yarns of the plating (Нп) and ground (Нг) threads are installed with different lead (Op) and (Oh), respectively, and the loop angle of the feed threads (βп) and (βт). In this case, the lead is greater for the plating thread, and the inclination angle is for the ground. Therefore, the plating thread will come out on the front side of the loop, and the ground thread on the wrong side.

The trajectory of the needles in section I is divided in the first needle selection node when the conclusion is made: the needles forming the background loops (needles 5, 6, 7, 9, 10, 11, 13, 14, 15) rise to a level higher than the full conclusion (VPZ ), and the needles forming the loop of the pattern (every fourth needle: 4, 8, 12, 16) and receiving only the filament of thread, rise to a level above the incomplete conclusion (VNZ). In section II, a plating thread (Hp) is laid on the needles forming the loop of the background, and on the hooks drawn on the pattern in section BK1 above the needles forming the loop of the pattern (needles 24, 28). Soil thread (Ng) is laid on all needles (needles 44-50 of section III) from the moment the thread is hooked onto the needle. At the time of pressing, the axis of the needle (level 3) crosses the bump plane (O-O), while the plating thread is above the axis of the tongue, and the ground thread moves freely under the needle hook (needle 51). By the time of application and connection (needle 55), the soil thread will be located closer to the hook, and the plating thread will be located farther from the hook, which will be preserved during the curing, dropping, forming and pulling operations (needles 56-62, section IV) and will ensure the exit of the plating threads on the front side of the loop, and dirt on the wrong side. Further, the needles forming the pattern loops, previously selected in section I to a level higher than incomplete imprisonment and holding the loops from the soil thread (needles 86, 90, section V), rise to a level higher than the complete imprisonment, go into the bowl of side hooks in section BK2 and grab located in the form of an outline on hooks, a plating thread, which upon subsequent raising of these needles (needles 94, 98, 102, etc. to 122, section VI) will descend as an outline to a previously formed loop of soil thread onto the needle shaft. Those needles that rose above the level of complete imprisonment (needles forming background loops) will rise one level above incomplete conclusion, while the formed loops of two threads (background loops) will lie on the core of these needles (needles 87, 88, 89, 91 etc. up to 136, sections V, VI).

Figure 2 shows the relative position of the needles forming the loop of the background (I1, I3), the needles forming the loop of the pattern (I2), and the side hooks, the threads and old loops when performing the operations of the proposed method in sections I-VI. So the operation of section I reflects the separation of the trajectory of the needles (1) for laying the thread of the thread, due to the individual selection of needles, namely: the needles forming the background loops rise to a level above the full conclusion (I1, I3), and the needles forming the loop of the pattern (I2), - higher than the level of incomplete imprisonment, while the old loops (3) are held at the level of the fender plane on the needle shaft. The operation of section II demonstrates the laying of the plating thread (Hn) on the needles forming the loop of the background (I1, I3), and the side hooks (2) extended over the needles forming the loop of the pattern (I2), the old loops are held on the needle shaft. The operation of section III represents the process of laying a ground thread (Ng) on both the needles forming the loop of the background and the needles forming the loop of the pattern (I2, I3) and holding the plating thread (Hn) on the needles forming the loop of the background and side hooks, while the old loop continues to be held on the needle shaft. The operation of section IV demonstrates the formation on the needles forming the loop of the background (I1, I3) of new loops from the ground and plating threads (background loops), and on the needles forming the loops of the pattern (I2), new loops of the ground only and holding the plating thread in the form of a sketch (H) on side hooks. The operations of sections V, VI describe the formation of pattern loops on some needles (I2), on the background stitches on others (I1, I3), namely: V reflects the operation of separating the trajectory of the needles in the second selection node, in which the needles forming the background loops (I1, I3) remain at a level above the incomplete conclusion, and the needles forming the pattern loops (I2) rise to a level above the complete conclusion to remove the sketch (H) from the cling thread from the retractable side hooks; VI shows the further rise of the needles forming the loop of the pattern (I2) with the loop of the pattern held on the needle shaft to a level higher than the complete conclusion and the side hooks move to the center of the rip washer, while the needles forming the background loops, on the core of which the background loops are held (I1, I3), occupy the same position as in the previous operation.

In figure 3. the structure of the knitwear produced on the basis of the smooth surface with a different orientation and arrangement of the pattern loops along the line of the stitch column and the stitch series is presented, which allows using a raw material of various composition and properties to obtain a pronounced pattern effect, which is a combination of relief, openwork, tint and color effects . Thus, the structure of knitwear under consideration contains a loop of a pattern in a column of 2 rows IV, in the form of a loop of ground thread (Нг) and a sketch (Н) of a plating thread (Нп), in a column of 4 rows III, IV, two loops of a pattern oriented along the line of a loop column and in columns 2, 3, 4 of row I of the rapport there are three loops of the pattern oriented along the line of the loop row.

Thus, the knitting method according to the invention makes it possible to obtain, in a single knitting cycle, in one loop-forming system with two knots, selectively on one needle the background loop of the platen and ground yarns, and on the other needles, the pattern loop of the ground thread and the outline of the platen yarn.
