Knitting yarn

1、 Gauze
It refers to the linear density of yarn, which generally reflects the diameter of the yarn.
A. Fixed weight system: that is to specify the length of yarn per unit weight. For example, 1s / 1 means that a 1lb yarn is 840 yards long, so the larger the number, the finer the yarn. For example, the 20s / 1 means that the length of the wire with the weight of 1lb is 20×840 yards. The larger the number, the finer the yarn
B. Fixed length system: specify the unit length. For example, 1D means that the weight of yarn with a unit length of 9000 meters is 1g, and 70D means that the weight of yarn with a unit length of 9000 meters is 70D, so the larger the number, the thicker the yarn.

  1. Artificial cellulose fiber:
    The main components are rayon, model, Tencel, etc. Among them, rayon’s strength is poor, especially the wet strength is worse, so it can’t do pc-merc. Rayon cloth generally has strength problems. Due to its nonreaction to the resin, its shrinkage is large, accompanied by problems such as slating & skew, and it is difficult to improve. The strength of the model is better, but the pilling is poor, and shrinkage and slating are difficult to control. Tencel has the highest strength. After special treatment, Tencel has no pilling problem.

Knitted fabric

One or more yarns fed from weft direction are bent into a series of loops by knitting needles, and then the new loop generated this time and the old loop generated last time are connected to form a knitted fabric.
Loop (k)
Set circle (T)
Floating line (W)

Jersey, pique, Lacoste, towel, and Terry are the most conventional and popular knitted single-sided fabrics.
Rib, interlock, French rib.
By using different finishing methods, different yarn count and yarn types, and adjusting different knitting processes and tension, we can achieve different customer requirements and styles of fabrics, such as handle, physical properties, and various functions.

The sweat cloth is composed of continuous and circular tissue, which includes ordinary sweat, woven Jersey and spandex.

Plated Jersey is formed by knitting two different yarns (different yarn types or different colors) at the same time. Cotton and polyester interweaved Jersey is the basic structure of moisture absorption and quick drying fabric

ELASTIC  Jersey

Spandex or DuPont Lycra yarn and another yarn such as cotton or polyester are knitted into a ring structure.
We can now produce three kinds of fabrics knitted at the same time

4F Pique

Oxford pique:The yarn of different colors is the ring forming and the ring collecting.
*Spandex bead: spandex is only knitted in the lap position, so the elastic quality is worse than that of spandex sweat cloth, especially in the horizontal direction.

4F Pique face 4F Pique back

6F Pique

The characteristic of 6 F Pique is that it is composed of one continuous loop and two collection loops on the same vertical path.

8F Pique

8F Pique It is characterized by two continuous stitches forming a circle and two continuous stitches gathering a circle on the same longitudinal path.

Twill Pique

Twill Pique structure is composed of a loop, two floating lines and a float stitch.

Athletic Pique

Athletic Pique structure is composed of two loops and a float stitch

conclusion

Usually, spandex have: 20d, 30d, 40d, 70D, and Core yarn: cotton as the surface, core for spandex, such as 40sx70d cotton spandex yarn
Spandex fabrics need to be performed to improve crease and stability. Spandex can be applied to the following fabrics:
Automatic inter Jersey and single bead, rib, and single terry fabrics. Spandex should not be used on the following fabrics:
Slub yarn and high twist yarn fabric, double sweater, suspension fabric. Hanma brand circular knitting machine can make any fabric of all over the fabric.
