Circular warp-knitted fabric and method of obtaining same

专利摘要:
The invention relates to knitwear production and improves the quality of the round basics of a hosiery jersey by producing knitwear with various physical, mechanical, technological and color parameters required, which allows them to be used for various types of solid or flexible cylindrical articles, high-pressure pipes and hoses electrical and optical cables, etc. The knit is made of a system of threads from 1 to N threads, with each of these threads forming from 1 to N - 1 looped columns, with N≥1. To make such knitwear, everyone at the same time lifts into the needle needles, after which a separate thread is applied to each needle and the needles are lowered below the thread line, causing one loop row. An individual thread is applied to a randomly selected needle after a preliminary turn at a certain angle.

专利说明:

The invention relates to round knitted knitwear with the basics of the knitted structure and the method of its production and can be used in the manufacture of flexible cylindrical hollow (or core) products, such as, for example, insulated with metal braid and sheathed electrical and optical cables, cords, erasers,
ropes for xm, mountaineering and caving, such as Knitkernmantle, reinforced high-pressure hoses, cylindrical packages, etc.
Known circular knitwear with the basics of the eaan structure (ed. Mon. NRB number 18304, class I) 04 V, 19/4), consisting of loop stitches, interconnected by longitudinal links
Kami, between which introduced a bunch of lining threads.
The disadvantage of this round knit is that each longitudinal link connects two adjacent hinge poles, which in turn causes low longitudinal elasticity and high lateral deformation, as well as weak adhesion to the core.
In addition, a method of obtaining a round knitted fabric is known, according to which, after all the needle needles are lifted simultaneously, the same main thread is applied successively to each pair of needles, which is applied by a spreading plate that performs a circular return motion directly above the needle cylinder.
The disadvantage of this method is that with a consistent feeding of the thread for every two, three or more needles, it is subjected to an overstressed voltage leading to the breakage and associated with it simply m, respectively, to a deterioration in the quality of knitwear.
Izvesgzn also knitwear with a base structure (ed. Mon. NRB number 32944, class I) 04 V, 1982), in which the hinge columns located around the core are opposite (diametrically) connected in pairs.
The lack of this round knitted fabric by the dog is that its basis for the nanach structure has certain (fixed) physicomechanical, technological and color parameters, for example transverse and longitudinal strength, transverse and longitudinal elasticity, modulus of longitudinal bend, porosity, adhesion to the core, etc., with a certain constant loop size.
In addition, a round knit has a necessarily even number of looped columns.
The method for producing knitted round knitted fabrics is that after all the needles are lifted simultaneously, the main threads round the center piece are fed back and round, and the main threads are going back and in circular motion with each thread diametrically opposed to it.
The disadvantage of this method is that the main thread system rotates a reciprocating circular pattern.

zones at a constant angle of 180, me i i is applicable only to a system consisting of an even number of main yarns, as a result of which one basic can be obtained from i hands, in which the looped links are located diametrically.
The aim of the invention is to improve the quality of knitwear by creating round knitwear with basic structure of increased transverse strength, with increased longitudinal elasticity and ohmic resistance, increased modulus of longitudinal bending, adhesion to the core, the possibility of color matching and reduced porosity, as well as the creation of a method its receipt from the system of the main threads of an arbitrary number, which would allow the fabrication of structures of different type and quality (weaves).
The goal is achieved by creating a round knit with a warp - a knit structure that includes looped stitches and looped links formed by the main thread system, and the thread system consists of one to N threads, and each thread alternately jumps from each 1 to N - 1 loop columns, in this case.
According to the method of obtaining round knitwear with a base structure, all the needles are simultaneously lifted, after which a separate thread is applied to each needle and the needles are lowered under the thread line, causing one looped thread to be applied to a randomly selected needle after first turning the thread to a certain angle of oil, which is directly proportional to the number of jumped (missed) needles and inversely proportional to the total number of needles and is defined by the formula

where is m; - the number of missed needles;
N is the total number of needles located at 360 around the circumference;
K - constant value, while the number of missed needles M; ranges from 1 to N - 1.
The application of the invention allows the manufacture of circular knitwear in a wide range of fundamentals of knitted structures (weaves) with various required physical, mechanical, technological and color parameters, such as longitudinal and transverse strength, longitudinal and transverse elasticity, modulus of longitudinal, bend, core bonding strength, ohm resistance, porosity, color, and others, which in turn allows their use for various types of solid or flexible cylindrical products, high-pressure pipes and Lange, electrical and optical cables, Knitkernmantle type ropes, erasers, cords and DR.
In FIGS. 1 to 6, six types of circular knitted fabrics with warp are shown - with a closed structure, knitted with seven needles; 7 to 12 illustrate the production of round knitted knit shown in FIGS. 1-6; FIGS. 13-18 are graphic and analytical recordings of the production of circular knitted fabrics according to the schemes shown in FIGS. 7-12; in Figures 19, 20 and 21, the use of knitwear respectively as a reinforced high-pressure hose, an electrically insulated and armored cable and Knitkernmantle type ropes, respectively.
