S.49.How can you tell if a knitted fabric is interlock or ribbed?
C.49. To determine whether a fabric is interlock or ribbed, stretch the fabric transversely and look at it, if the opposite loops are opposite each other, it is interlock. In simple terms, if it is full, it is an interlock. Ribada comes back to full, empty and empty.
S.50. What are the settings made for the RR interlock knitting to be ready for the machine?
C.50. In order to produce RR interlock knitting, the machine must be prepared. In order for the machine to be ready for knitting, needle selection, steel selection and may density adjustment, thread tension adjustment, machine speed adjustment and fabric drafting settings must be made.
S.51. How many needle groups are in the circular interlock knitting machine and what are their names?
C.51. There are two different needle groups in the circular interlock knitting machine, a cover needle and a cylinder needle.
S.52. What is the difference between cap needles and cylinder needles of interlock machines?
C.52. Cap needles of interlock machines are short and cylinder needles are longer than cap needles. In addition, the cap and cylinder needles are in two different foot lengths.
S.53. How should two needles with different lengths of feet be aligned when needle alignment of interlock machines is done?
C.53. When needle arranging of interlock machines, two needles with different lengths of feet should be placed side by side. The same process applies to all cap and cylinder needles.
S.54. When the needle arrangement is completed, how is the arrangement of the short-footed needle on the cover and the long-footed needle on the cover?
C.54. When the needle arrangement is completed, the long-footed needle in the cylinder should be opposite the short-footed needle on the cover, and the short-footed needle in the cylinder should be opposite the long-footed needle on the cover.
S.55. How many rows is the knitting report of the interlock knitting?
C.55. The knitting pattern of the interlock knitting is two rows.
S.56. In how many systems does the knitting of the RR interlock fabric take place?
C.56. Knitting of RR interlock fabric takes place in two systems.
S.57. In knitting RR interlock fabric, which needles make loops in the first row of knitting?
C.57. In the first row of knitting, only short-footed needles loop, while long-footed needles do not move. In the second row, long-footed needles make loops. The steel system of the machine should also be adjusted according to this weave.
S.58. In knitting RR interlock fabric, which needles make loops in the second row of knitting?
C.58. In the second row, long-footed needles make loops.
S.59. What is the difference between a 54 system rib machine and an interlock machine in RR knitting and what does this tell you?
C.59. While the 54 system rib machine knits 54 rows in one round in RR knitting, the interlock machine knits 27 rows in one round in RR knitting. This tells us that the production performance in Interlock machines is different from other machines. He explains that the production in these machines has fallen by half.
S.60. Explain the yarn tension setting in double plate interlock circular knitting machines?
C.60. For RR normal interlock production, the feeding of the yarns should be from the same pulley. Because the yarn consumption of each system is the same when we look at the knitting report. In addition, the yarn density of the sample fabric should be taken into account in the yarn tension adjustment made from the hoop. If you turn the pulley in the positive (+) direction, you will send more yarn and the knitting will be heavier. If we want to reduce the weight, the pulley belt should be tensioned by turning the pulley in the minus (-) direction.
S.61. How was the pattern formed in RR interlock knits?
C.61. RR interlock hanging knits are creating patterns with the help of hanger movement as well as looping on the same row.
S.62. How are RR back lay knits knitted on interlock circular knitting machines?
C.62. RR back lay knits are knits obtained by skipping the back ie cover needles in some systems in interlock circular knitting machines.
S.63. How are knitted fabrics produced in RR back lay knits interlock circular knitting machines?
C.63. With this system, fabrics with a raised front surface are generally obtained.
S.64.In which order should all the needles on the cover and cylinder of the machine be for the back laying interlock knitting?
C.64. All of the needles on the cover and cylinder of the machine must be in interlock order for the back laying interlock knitting.
S.65. What is rib circular knit fabric?
C.65. Rib circular knitted fabrics are a type of double-layered knitted fabric obtained by placing the cylinder and cover needles in a diagonal manner relative to each other in double-plate circular knitting machines.
S.66. What are the biggest features of rib fabrics?
C.66. The biggest feature that expresses rib fabrics is that when the fabric is opened in the width direction, straight (R) and reverse (L) loops appear alternately depending on the knitting pattern on both sides. The structure of the fabric consists of consecutive straight and reverse loops in the vertical row direction. Rib fabrics are knitted fabrics with the most flexibility in the transverse direction.
S.67. Explain the importance of machine speed adjustment in double plate rib knitting machine.
P.67. Excessive speed in circular knitting machines causes wear of needles and steels. Especially since rib circular knitting machines work with double plate, they should be operated at a lower speed compared to single plate machines. In addition, the type of knitting is also effective in adjusting the machine speed. When knitting RR flat rib knit, the speed must be adjusted more carefully as all needles are working.
S.68. Explain the importance of yarn tension adjustment in double plate rib knitting machine.
C.68. In all circular knitting machines, the tight or loose yarns coming to the systems affect the knitting. By adjusting the rotation speeds of the furniers that provide yarn delivery to the systems, the desired feature of the knitting can be achieved. If the speed of the furniers is slowed down, the yarn becomes more taut, and if the speed is increased, the amount of yarn transferred is greater and the yarn becomes loose. This situation has a great effect on the unit weight of the fabric. If the yarn is stretched, a tighter knitting surface is created and the fabric weight increases. As in all circular knitting machines, yarn tension adjustment is made with pulley adjustment in rib machines. Enlarging the diameter of the pulley will result in more yarn delivery, and narrowing the diameter will result in less yarn delivery. This setting should be adjusted well according to the sample, fabric properties and knitting report.
S.69. Explain the importance of steel selection and may density adjustment in double plate rib knitting machine.
C.69. The choice of the steel system is also important in knitting the RR rib fabric. The fabric to be produced is formed by completely looping the needles on the cover and the cylinder. Therefore, all steels of the machine should be adjusted as loop steel. Although it differs slightly in appearance according to the machine models, the general appearance of the loop steel is similar to a triangular shape. If there is a different steel on the machine, it should be replaced. If the machine has a double track steel system, both steels should be set as loop steel. Loop steel is also commonly called single jersey or knitting steel in the knitting industry. After the steel systems of the rib machine are adjusted and placed on the flat rib weave, the loop length (may) adjustments must be made from the loop adjustment steels on the steel (lock) covers. May adjustment cannot be made in bulk on all knitting machines. On each steel cover, there is a may adjustment section for the steel belonging to that system. While setting the may density (loop length) on circular knitting machines, it must be the same in all systems in flat knitting patterns. On the other hand, in double plate rib machines, adjustment must be made from both the cover and the cylinder. Adjusting the knitting frequency on the knitting machine is the most important factor in determining the number of rows of stitches per 1 cm. For example, on the same knitting machine, 1 rows of loops per 10 cm can be formed in the first of two different fabrics, and 20 rows of loops in the second. Of these knits, the fabric with 1 loop bars in 20 cm will be harder and heavier in terms of weight. The way this process is done is by reducing and enlarging the may setting. The smaller the number on the indicator, the smaller the pressure applied to the heel of the needle and the smaller the loop size. In other words, the number of rows of loops per unit size increases. As the number increases, the pressure on the heel of the needle will increase and the loop size will increase. The number of rows of stitches per unit measure will decrease.
