    C.305. It shows the Open Loop Structure of Harosha Fabric.













    Q.306. What does Relaxation Shrinkage mean in knitted fabrics, please explain?


    C.306. Relaxation Shrinkage: This shrinkage, which is seen in all knitted products, is the dimension that occurs after the fabric is completely relaxed and released from the stresses on it. is change. In order to prevent this pull; Knitted product should not be stretched more than finishing processes, it should be processed comfortably and freely. During the knitting process, the fabric should not be stretched too much. However, the presser-foot mechanism should be used on the fabric. At the same time, a normal density knitting design should be built, avoiding too tight and loose weaves.


    P.307. What are the Fabric Defects Caused by the Printing Process in Knitted Fabrics?


    C.307. Flow - Contour uncertainty - Slip - Keleşlik - Halo - Squeegee line


    P.308. Fabric Defects Caused by Printing Process in Knitted Fabrics flowing what does it mean?


    C.308. Flowing; It is the fact that one color flows, contaminates the other color and disperses in the area where the other pattern is located, during the washing processes of the prints due to poor fixation and poor dyestuff fastness.


    P.309. Fabric Defects Caused by Printing Process in Knitted Fabrics contour ambiguity what does it mean?


    C.309. Contour uncertainty; It is because the viscosity of the printing paste cannot be adjusted well, the edges of the pattern are not sharp and clean lines, but rough.


    P.310. Fabric Defects Caused by Printing Process in Knitted Fabrics slip what does it mean?


    C.310. Slip; the pattern is not properly seated because the pattern templates or rollers are not properly aligned.


    P.311. Fabric Defects Caused by Printing Process in Knitted Fabrics heirloom what does it mean?


    C.311. Keleslik; Due to the low pressure of the squeegee and the extremely high paste consistency, the whiteness in the motifs and the sharpness in the contours are seen in the motifs due to the inability to transfer the paste to the fabric sufficiently in the printing.


    P.312. Fabric Defects Caused by Printing Process in Knitted Fabrics Tail what does it mean?


    C.312. halo; The appearance of a third color, which is formed by the overlapping of two colors in the pattern at a point close to each other during printing, is called halo.


    P.313. Fabric Defects Caused by Printing Process in Knitted Fabrics squeegee line what does it mean?


    C.313. squeegee line; As a result of damage to the blade of the squeegee, lines occur due to the inability of the squeegee to scrape the paint.


    P.314. What are the general differences between knitted fabric and woven fabric?




    A-Knitted fabric production is faster than woven fabric production.


    B-Knitted fabrics have a flexible structure, but there is no stretching in woven fabrics (except lycra).


    C-Knitted fabrics have a higher moisture absorption feature than woven fabrics.


    Ç- Knitted fabrics have a higher shrinkage tendency after washing than woven fabrics.


    D- Knitted fabrics are less wrinkled than woven fabrics. For this reason, folding and packaging is easier and faster.


    E- Knitted fabrics are more draped. It hugs the body easily. Even if woven fabrics are draped, they do not fit the body curves and do not give the comfort of knitted fabrics.


    F- Knitted fabrics do not need to be washed after being sewn, they reach the consumer ready to use. The products sewn from woven fabrics are washed after sewing, then prepared and sent to the consumer in order to obtain the desired result in touch, sewing effect and appearance, depending on the fabric type and place of use.


    G- Products made of knitted fabric are produced as socks, tights, singlets, underwear, sweats, t-shirts, tracksuits (bottom and top), baby clothes, while trousers, shirts, jackets, coats, coats, salopets, shorts, raincoat is produced.


    p.315. What are the general characteristics of knitted fabrics?




    A-Knitted fabrics have inherent elasticity and the ability to return to their original position after stretching,


    B- Easily adapt to body movements,


    C-Insulation in stagnant air


    They require little or no T-Ironing.


    The D-Loop escapes easily and they come loose.


    They will pull unless e-stabilized.


    F-The variety of thickness and weight that can be worn in all seasons of the year is valid for knitted fabrics. Again, they provide better insulation than woven fabrics with the same meter-tulle weight.


    G-Knitted fabrics do not have as strong covering properties as woven fabrics. Knitted fabrics can keep warm in cold weather conditions


    P.316. What are the general characteristics of woven fabrics?




    A- Woven fabrics are produced on simple or complex weaving machines that combine warp and weft threads at right angles.


    B-Weft and warp densities can be very variable; Voile:44 yarn Poplin:100 yarn


    C- Fabrics suitable for all climatic conditions are produced.


    D-Surface structure can be open, sparse or non-porous. Cheesecloth, coat, trousers.


    D-They can be very light or very heavy: 50-60G/M2 Voile 250003000G/M2 carpet.


    They are E-Stable.


    F-Pulls vary depending on the weave; but it is less than knitting. Thread density is important.


    G-Handling properties vary according to yarn type, yarn density and applied finishing processes, it is harder than other textile surfaces.


    Ğ-It is solid because the distance between the threads is small.


    H-All kinds of weaving can be made from any kind of fiber


    By changing the I-Knitting type, unlimited fabrics can be created with different patterns.


    -İ-When elastic yarns are not used, the flexibility is very low and the least stretching is in the warp direction and the most stretching is in the 45 angle part.


    J-Wrinkling tendencies are generally high. On the other hand, it has high ironing properties.


    Due to their K-stability, they show easier cutting and sewing features in ready-made garments.


    Number of L-Thread systems: Warp thread system and Weft thread system.


    M-Elasticity and flexibility: There is elasticity and flexibility in the oblique direction. Less in the direction of the weft thread; In the warp thread direction, it is almost absent.


    N-Moisture absorption: Woven fabrics absorb less moisture than knitted fabrics.


    S.317. Write the parts of the hook-tipped latch needle shown below on the figure.

























    P.318. What is the name of the needle seen below?













    C.318.It is a hook-tipped latch needle.










    Q.319.Write the names of the needles seen below?
