Description

one

The invention relates to a knitwear industry, namely to the development of a curly knit with a longitudinal weave.

Known kulirnyj knitwear containing looped primer and yarn longitudinal weft 1 ..

In this canvas, the longitudinal weft yarns are fastened with a thread of interlacing with a thread and a ground coat and are laid out through one bar. Such a web, produced from yarns having a low yachting coefficient, for example glass, has an insufficient dimensional stability due to the weak fixation of weft yarns. The elasticity in the radial direction of such a web is small because the soil is maximally stitched by the main threads worked into each gap between the hinge columns, so it is impossible to get smooth coning-shaped products without folds on its basis.

Another, knitted knitwear is known, in which dimensional stability is improved by inserting and binding together with a ground filament. In such a knitwear, the threads of a longitudinal weft are firmly fixed between the lengths of the loops of soil

YOU AND the coverslip threads in each looped row and laid also in each gap between the looped columns. In addition, this attachment has a transverse duck in each loop stitch, which completely looses its mobility in the radial direction and significantly increases its consumption of materials 2.

The purpose of the invention is to increase the mobility (elasticity) of the material in the radial direction while retaining sufficient longitudinal strength, making it possible to use it as a reinforcing material in the manufacture of hollow conical fiberglass products that work in bending in the axial direction, such as masts for sailing ships.

This is achieved due to the fact that the soil consists of a series of single-strand cool surface smooths alternating with rows of cover loops, and the longitudinal weft threads are located in the soil at least through two looped columns.

FIG. 1 shows the structure of the knitwear; FIG. 2 - filling the machine; in fig. 3 is a diagram of the mutual arrangement of the threads at the time of laying. Culinary knitwear contains looped rows of a single-filler curtain from the thread of the soil 1, alternating with the looped rows of the covering surface of the cover thread 2, and the thread of the longitudinal weft 3. Thread 3 through the tensioner 4 and the threadguide 5 is fed into the zone in the low. The thread 1 from the packages on the table 6, which rotates synchronously with the locking mechanism 7, is fed through the yarn guide 8 to the tongue needles 9 located in the slots of the needle cylinder 10. The yarn 2 is also fed to the needles 9 through the guide hole 11. Soil thread 1 8, made in the form of a ring with holes by eyelets, which rotates synchronously with the locking mechanism 7, is fed to the needles 9 from the inner side of the cylinder 10. The number of ground threads 1 is half the number in the machine's imbedded systems. The cover thread 2 from the packs mounted on the lower table of the machine, which also rotates synchronously with the locking mechanism 7, passes through the guide hole 11 and is fed to the tongue needles 9 from the outside of the cylinder 10. The number of the cover threads is equal to the number of the idlers. The weft thread 3, the packages of which are mounted on a round multi-light frame, passes through the tensioning device 4, the yarn guide 5, which is a ring with threading-tube pipes assembled into it, and is fed into the zone in the undercarriage (see Fig. 3). in the inter-needle space between the primer and the covering thread, thanks to whom. Inserting into the web between the threads of the primer and the covering thread through one looped row. Moreover, the weft threads are laid every two looped columns and they should be much thicker and stronger than n It is 1 and 2. The presence of vertical strips of a kulirnaya smooth surface without a weft ensures its elasticity (extensibility or compressibility) in the radial direction, due to which high-quality conical products made of fiberglass can be obtained from a cylindrical tubular billet breaks, such as hollow masts for sailing. The laying of weft yarns between the stitches from the ground and the covering yarns ensures sufficient dimensional stability of the web, and their fastening through the looped row considerably reduces the material consumption of the blade, while there is no need to fix the weft in each looped row, since the main strength elements providing the strength of the mast in the axial direction are weft yarns, and the tiller smooth surface only plays the role of a tie until the end of the molding process and the hardening of the fiberglass mast. The use of weft knitwear as a reinforcing material in the manufacture-. sailing masts gives an economic effect of 8 thousand rubles. per ton of fiberglass, and also allows you to increase the service life of the mast by 3-5 years. Claims of knitwear containing soil formed from ground and surface threads and longitudinal weft threads fixed between the stitches of cover loops, characterized in that, in order to be able to use it as a reinforcing material for the manufacture of conical fiberglass products, the soil consists from the rows of single-filigree smooth surfaces alternating with rows of cover loops, and the longitudinal weft yarns are laid into the soil through at least two looped columns.
