E) Tuck or double stitches
F) Bunching up
G) Vertical stripes
H) Horizontal stripes
I) Color fly
J) Distorted stitches

A) Broken ends:
If the yarn is torn or cracked, a hole is created in the fabric. During the formation of the loop, a hole is formed in the needle hook if the thread is already torn. These holes come in different sizes. It depends on the knitted structure, yarn count, machine gauge, and course density. This hole can be on the front or back of the fabric or both sides. https://bdfabric.com/quality-parameters-for-woven-knitted-and-non-woven-fabrics/
B) 10 knitting defects that occur during knitting-Drop stitches:
This is usually due to a defective needle. This type of error occurs when the yarn is not properly supplied during the formation of the loop, i.e. the needle hook is not properly threaded. This defect can also be made on both sides of the fabric. In addition, if the yarn feeder is not installed properly if the yarn is not inserted properly in the yarn feeder if the take up is bad and if the tension in the yarn is not enough, drop stitches are created in the fabric. https://bdfabric.com/what-are-production-plans-and-equipment-control/
C) 10 knitting defects that occur during knitting-Cloth fall out:
This is called cloth fallout when some drop stitches come along and take up space. This type of defect occurs when a needle is not attached to the needle hook or if the thread is torn and not attached immediately. https://bdfabric.com/what-is-process-control-in-the-textile-industry/
This defect is seen when making fabrics with only continuous filament yarn. Some of these yarns have knitting or, in a subsequent process, a mechanical strain that is responsible for this defect despite its specific fragility. Here the filament or yarn goes out of the fabric.
E) Tuck or double stitches:
Badly knitted or non-knitted loops cause such errors. This defect can be seen as small beads or thick places in the fabric.
F) Bunching up:
Visible knots in the fabric are called bunching up. These are observed as beats in the fabric.
G) Vertical stripes:
When a long space is seen along the vertical in the fabric, it is called a Vertical stripe. The space between the adjacent wells is uneven. For specific machine gauges if the yarn count is selected very fine, and then if the size of the stitch or the density of the course is not correct such error is seen.
H) Horizontal stripes:
If there is inequality between the courses then this error is seen. It crosses horizontally and crosses evenly or unevenly and this error is seen evenly or unequally. This defect can be seen on both sides of the cloth. This error occurs when the yarn feeder is not properly attached to the dial camp deflector tuck position, and the yarn is not tightly tied.
I) Color fly:
It consists of a single fiber or a bunch of fibers of different colors consisting of a yarn piece. It additionally comes with yarn or is knitted in fabric.
J) 10 knitting defects that occur during knitting-Distorted stitches:
This creates an unsettled fabric appearance in the fabric. Its single color causes more inconvenience for products. If the setting of the knitting machine is not correct, especially if the coulier depth between the dial and the cylinder needle is uneven, then this error is seen more.
