P.373. What is the number of systems in Electronic Knitwear Machines, please explain?

C.373. The steel device (lock) that adjusts the selection, movement and tissue density of the needles on the front and back plates carried by the saddle is called the system. Steel mechanism can be more than one. Single system for machines that can knit at most one knitting row in one go of the saddle; Machines that can knit at most two rows are called double system machines. Today, there are machines with the number of systems from one to six. These are carried by one or two saddles. These saddles can be combined or work separately. The knitting systems of flat knitting machines can also work together. When operated in combination, the number of systems doubles. When the heads are combined, the machine can weave fabric across the full width. When the head is combined in the machines, the side steels in the joints should be replaced.

P.381. Electronic Knitwear Machines technical specifications number of saddles Classify by?

C.381.Knitting machines work as single saddle and double saddle.. However, all of the machines that are called compact machines today have a single saddle. These machines can produce more serially and faster. Old type machines work as double saddles.. However, these machines can work as a single saddle by combining two heads.

Q.382.Basic knitted surfaces are determined according to what fabric and what are these surfaces?

C.382. Basic knitted surfaces are expressed as (RL), (RR) and (LL) surfaces according to the loop image of the knitted fabric face and reverse. These;

1. RL Plain knitted surfaces, Single jersey knitted surfaces.

2. RR knitting surfaces, Rib and Interlock knitting surfaces.

3. LL knitted surfaces, Harosha knitted surfaces.

Q.384. What does intelok knitting mean?

C.384. When two rib knits are knitted at the same time, it is called Interlock Knitting.

P.385. What knitting surface does Harosha knitting have?

C.385. Harosha knit has LL knit surface.

S.386. In which knitting machines are rib fabrics produced and what is its structure?

C.386. Double plate knitwear (flat knit) is a double layer knitted fabric produced on circular and warp knitting machines.

Q.387. Could you give information about Harosha knitting?

C.387. Harosha knit has LL knit surface. If the face of the knitted fabric is left loop (L) and reverse left loop (L), these surfaces are called (LL) surfaces. Harosha knit fabrics are single-ply fabrics in which both straight and reverse loops are grooved in a single weave. The reverse side of a plain knitted fabric is dominant on both sides of the fabric. They consist of consecutive rows of straight loops and reverse loops on both sides of the fabric, knitted through each other, in the opposite direction from each other. In this context, Harosha comes to the forefront with its difference from rib knits consisting of plaid and reverse loop bars sequentially.

The simplest harasho fabric is the one in which one row, known as 1*1 reverse, consists of completely straight loops and the next is completely reversed loops. Successive rows of straight and reverse loops combine to form horizontally oriented semi-circular loops on the front and back. Since the shrinkage of this type of knitting is high, the production amount is accordingly low. Length shrinkage rate is around 40-50%. Harasho knits can be produced on both flat and circular machines.. Two rows of needles are needed in the production of these fabrics, as the loops are sometimes pulled to the front and sometimes to the back. In Haraşo machines, instead of using two separate needle sets, one set of double-edged needles is used. These two-edged latch needles will pass from one bed to the other as they pass through each course of the fabric alternately. They are produced in the market with double-headed hooked latch needles, which work in two needle slots and are moved by the sinker, under the name of Lifado.. Jacquard patterning is possible in this weave. Haraşo knits do not spin like jersey knits. Haraşo fabrics are thicker than jersey fabrics. Another feature of these fabrics is that their maximum stretch is longitudinal. This is due to the widespread use of these fabrics in baby and children's clothing.

P.388. What are the main features of interlock fabrics?

C.388. 1-They have the same appearance on the front and back, they are double-sided knitted fabrics.

2- Pattern and surface design are limited,

3-Can only be produced in double plate circular knitting machines,

4- Its front and back sides are smooth,

5-It has a dense structure,

6- Since the knitting pattern is in the double plate and creates a row from two systems, the amount of yarn spent is the highest,

7- It may have a very fine or coarse machine fineness,

8- It is the thickest single-thread knitted fabric produced on the condition that the knitting pattern is formed on the double plate and on the opposite needles and on the condition that it remains the same in the raw materials used. The knitting pattern consists of at least 2 needles at the back and front and 2 rows of loops on top of each other.

9- It has a higher elasticity and flexibility in the vertical direction than in the horizontal direction,

10- It has limited elasticity and flexibility in the horizontal direction,

11-Dimensional stability and shape preservation feature is high,

12- Compared to other single yarn knitted fabrics, the highest weight knitted fabrics can be obtained,

13- When subjected to tension, the loop tends to escape from one edge,

14- As in rib knitted fabric, if the number of loops on the front and back are equal, the loops on both sides will balance each other and curling will not be seen on the edges as in single-layer fabrics. RR Interlock knitted fabrics can only turn from the last knitted end. Since the air is kept between the two knit layers, they have a warmer feature than other single yarn knitted fabrics,

15-Due to its bulky structure, interlock knitted fabrics have a good moisture absorption feature, a striped pattern can be obtained by using different yarns or colors in successive shuttles,

S.389. What are the general characteristics of rib fabrics?

C.389. 1- If the number of reverse L and face R loops is equal, the same image is formed on the front and back of the fabric. So it's double faced

2-Double plate knitwear (flat knitting), double layer knitted fabric produced in circular and warp knitting machines,

3- The knitting pattern consists of at least 2 needles and 1 yarn movement in the double plate (normal, the main knitting pattern consists of 2 needles side by side and 2 rows of loops on top of each other).

4- Since the knitting pattern is formed in double plate, the amount of yarn consumed is higher than single jersey fabrics,

5- It has high elasticity and bounce feature,

6-Longitudinal stretching feature is low. Flexibility in the transverse direction is high,

7- Stretching in the transverse direction is more than plain weaves,

8-Rib knit fabric adapts to the body due to its high stretching feature,

9- If the number of loops on both sides of the knitted fabric is equal, the loops on the front and back will balance each other, so that curling will not be seen on the edges. That is, it has the ability to lie flat on both ends and edges.

10-Can only rotate from the last loop,

11-There can only be escaping from the last stitch,

12- It can have equal or different design, balanced or unbalanced ribs (longitudinal R loop arrangement),

13- Provided that the raw materials used remain the same, the thickness of the rib fabric is thicker than the single jersey fabric,

14- It can be used in upper clothing knitting as plain or shaped,

15- It can be applied to the edge of woven or different kinds of fabrics,

16-RR Rib knitted fabrics have good moisture absorbing properties with their bulky structure, thus absorbing properties are good.

17-RL Higher weight fabrics can be obtained compared to single jersey fabrics,

18- Circular positions are smooth due to the height of transverse elasticity,

19- Since the air is kept between the two layers of knitting, it keeps the body warm,

20- They have found a wide area of ​​use as a rubber knit in underwear and outerwear, especially in the sleeves, collars and waist parts of which elasticity is desired.
