(a)     Twisted Type
(b)     Braided Type

Generally twine is understood as 3 strand-twisted twine, but it can be twisted in 2 strands, 4 strands, 7 strands or 11 strands also depending on requirement.
Braided Twine is different from twisted twine and is braided in 8 strands or 16 strands.

There are two directions of twist as you can see in the illustrations. Namely "Z" type is generally called LEFT twist and "S" type called RIGHT twist.

(a)     Z TWIST   (Left Twist)
(b)     S TWIST   (Right Twist)

4.       NUMBER OF PLY AND STRANDS OF TWINE USED

(a)     Number of plies means total number of single yarn twisted together to compose twine.
(b)     Number of strands means of set of yarns twisted together to compose twine.

(a)     Soft Twist
(b)     Medium Twist
(c)     Hard Twist
(d)     Extra Hard twist

If not described, degree of twist is regarded as "Medium".

(a)     Single English Knot (S/K)
(b)     Double English Knot (D/K)
(c)     Knotless Rachel Type
(d)     Knotless Twisted Type

If not described, type of knot is generally regarded as "Single English Knot".

There are many methods of describing the mesh size. It, therefore, should be clearly described in any order sheet.

a)     Stretched Mesh
        It is usually measured in "Inch" or "mm" from the   
        centre of  a knot to that the second next knot.
(b)    Half Mesh or Square Mesh
         It is generally measured in "mm" from the middle of a knot to the middle of the neighbouring knot.
(c)     The size mesh can be shown by number of knot in the unit of length.
(d)     Mesh size can be measured by JAUGE: Inner stretched mesh measurement between end of a knot to the beginning of second knot

• Omfar measurement
This measurement is the number of half meshes in one Alen, and is adopted in Sweden and Norway. One Alen : 0.628Meter in Norway,0.549 in Sweden.
• Measurement by the number of rows per yard
This measurement is by the number of half meshes in one yard, and it is used in Holland. One yard: About 0.914 Meter
• Measurement by the number of knots per meter
This measurement (Passales) is by number of half meshes in one meter, and used in Portugal and Spain.
• Measurement by the number of knots in 6 inches
This measurement is used in Korea, Formosa, the Philippines, Japan and other countries in East Asia.

The netting can be stretched and heat-set by two ways, one is called DEPTHWAY STRECHING, and the other is called LENGTHWAY STRETCHING. This information is very important since this heat setting direction's causes convenience or inconvenience for mounting and mending nets.

(a)     Depthway stretched and folded:
         Stretched and heat-set depthway, namely along the mesh depth, from selvage to selvage. (400MD X 1,000ML)
(b)     Lengthway stretched and folded:
         Stretched and heat-set lengthway, namely along the length of the net. (400MD X 1,000ML or  400MD X 100yds)
(c)     Telaknot Stretching method:
         A lengthway stretching machine is used to stretch nets in Depth way, but nets specifications are reversed (1,000MD X 400ML)
