It is the main weave twill, which is the most used and the most variety. Especially men's and women's fabrics and overcoats etc. Twill weaves are mostly used in all outerwear. The smallest twill consists of the connection of three warp and three weft threads.
Twill weaves are tied one after the other with each warp with its own weft.
That is, the first warp is made with the first weft, the second warp with its own weft and the others continue accordingly. Therefore, the connection points form a path (diagonal) to the right or to the left. This inclination that appears in this line “DIMI WAY” It called.
What are impacted teeth?
When one or more teeth fails to grow in the correct position and is therefore held below the normal gum line, it is called an impaction. This can be complete, such as completely unerrupted (buried) third molars (wisdom teeth) or partial when just part of the tooth is visible in the mouth.
Why are impactions important?
For best function and appearance the teeth should grow in a healthy alignment. When one or more teeth is impacted, this can affect the function of that tooth but also the function and appearance of other teeth.
Whether all impactions should be treated is still controversial and your dentist and oral and maxillofacial team can explain the advantages and disadvantages or treatment for you, which is usually surgical.
If the warp yarns are in the majority on the face of a fabric woven with twill weave, the wefts are in the majority on the reverse.
If the twill path on the face of the fabric is from left to right, on the reverse it is from right to left. The twill path also has an angle; It takes different situations according to the thickness (number) and density of the warp and weft threads used. Namely;
1- If the thickness and density of the warp and weft yarns are the same, the angle of the Twill path is 45 degrees.
2- If the wefts are twice as thick as the warps or the warp density is the same as the weft density, it is seen that the angle of the twill path is 63 degrees.
3- If the thickness of the warp yarns is twice as much as the wefts or if the weft density is higher than the warp at the same rate, the angle of the twill path becomes 27 degrees.
One more point needs to be clarified here. While defining the twill weave, we stated that normally each warp connects with its own weft and one after the other. Since these twills are generally used, we are at the beginning of the subject, so they are defined like this for ease of understanding. The changes that occur in the conditions put forward while examining the twill path angle above are also for these twills. However, the twill path angle gains different values according to the connection types of some warp and weft threads. These can be listed as follows;
- 1- If the warp yarns make their connections with their own wefts one after the other, the angle is 45 degrees.
- 2-If each warp thread connects with two wefts, the twill path makes an angle of 63 degrees.
- 3- Conversely, if each weft connects with two warps, the twill path angle will be 27 degrees this time.
If we pay attention to the figures, it is seen that both evaluations reach the same point. It is only the circumstances that differ. Otherwise, the result does not change in terms of appearance, since the warp density is twice that of the weft and the connection of each warp with two wefts will give the same appearance.
CHARACTERISTICS OF TWILL BRAID
- 1-The smallest report area in twill weaves consists of 3 warp and 3 weft threads.
- 2-The front and back sides of the fabrics woven with twill weaves are different.
- 3-The number of warp and weft wires in the twill weave pattern is equal.
- 4-The fabric can be woven more frequently than plain weaves.
Above is the fabric image of 2 top (full) 2 bottom (empty) Right-way Twill weave.
Below is 5 upper (full) 1 lower (empty) left-handed twill weave.
Twill weave 3 reports are seen. Here, the area marked in brown is the weave's report, and the area marked in blue is the repeat of the pattern. The number above the knitting line indicates the warp, and the number below the knitting line indicates the weft. Twill is read as 5 full and 1 blank. Or read as 5 upper 1 lower. The sum of the numbers above and below the knitting line gives the number of warp and weft wire that should be in the report. Here 5+1=6. So the pattern of this twill weave consists of 6 warp threads and 6 six warp threads (6x6). This means that 3 reports can be made; 6 warpsx3 weaves=18 and 6 weftsx3 weaves =18. In other words, this pattern consists of 18 warp and 18 weft threads.
Let's draw the twill weave shown below.
First, we determine the warp and weft borders of the weave that we will draw on our pattern paper. We added the numbers above and below the knitting line. 2+2=4 So our pattern will consist of 4 warp and 4 weft threads. Twill way is Right (Z) way.
It is the square starting place where the 1st warp thread and 1st weft thread intersect. Here, we fill 2 squares upwards. Well; We fill the square where the 1st warp thread and the 1st weft thread intersect, and the square where the 1st warp thread and 2nd weft thread intersect.
Starting from the square where the 2nd warp thread and the 2nd weft thread intersect, we fill TWO squares upwards. Well; We fill the square where the 2nd warp thread and the 2nd weft thread intersect, and the square where the 2nd warp thread and 3rd weft thread intersect.
Starting from the square where the 3rd warp thread and 3rd weft thread intersect, we fill TWO squares upwards. Well; We fill the square where the 3rd warp thread and the 3rd weft thread intersect, and the 3rd warp thread and the 4th weft thread.
Starting from the square where the 4rd warp thread and 4rd weft thread intersect, we fill TWO squares upwards. Well; We fill the square where the 4rd warp thread and the 4rd weft thread intersect, and the 4rd warp thread and the 5th weft thread.
However, our report consisted of 4 warps and 4 wefts. In other words, we went beyond the specified report limit. So we filled the square where the 4th warp and the 5th weft intersect. We brought this full movement to the square where the 4th warp thread and the 1st weft intersect.
In this way; We have made (drawn) right-way 2 upper (full) 2 lower (empty) twill weaves.
