A, about the weaving of socks
Socks composition: Socks belong to weft-knitted fabrics. The main components in the sock machine are: triangle, socks, raw gram, jacquard, and wire shuttle. The specific role is as follows:
The role of the triangle: so that the socks, raw grams, jacquard needles move according to a certain trajectory.
The role of the sock needle: under the control of the triangle, the knitting needle makes radial movement, through the steps of adding yarn, bending, long circle, uncoiling, retracting and so on, to achieve the task of hosiery.
The role of the raw tablets: under the control of the eyebrow triangle, the raw grams of the film to do the latitudinal movement, to prevent the buckle when the needle is off the ring.
Jacquard needle function: Under the control of the triangle and the jacquard blade, the needle needle is controlled by itself to achieve the purpose of making the flower pattern.
The role of the wire shuttle: the knitting needles are regularly woven.
B. About the caliber and number of needles in the sock syringe
The size of the syringe in the sock machine determines the size of the socks. According to the age, the socks are divided into: men's socks, women's socks, children's socks, etc. The commonly used calibers are 41/2, 4, 33/4, 31/2, 31/4, etc. The coarse needle machine is generally used: 4, 4 1/2, the caliber of men's and women's socks is commonly used: 4, 33/4, 3 1/2. Children's socks, and baby socks are commonly used in calibers of 31/4.
The number of needles in the needle machine determines the thickness of the yarn, and the number of needles commonly used in cotton socks is. 200, 176, 168, 156, 144, 132, 120, 108, 96, 84, etc., commonly used in stockings are: 480, 400, 280, 240, 200, etc., the larger the number of stitches, the finer the yarn.
C. Yarn about socks

D, about the raw materials of socks
Textiles can be roughly classified into the following categories: a: plant fiber type b: animal fiber type c-fiber type and recycled fiber type.
Plants include: cotton, hemp. Kapok and so on.
Animals include: wool, rabbit hair, camel hair, silk and the like.
Chemical fiber types include: polyester, polypropylene, acrylic, nylon, etc.
Synthetic fiber refers to the raw material of the combination of two raw materials, including: cotton, cotton, cotton, cotton, and cotton.
E. Characteristics of the burning of raw materials for socks:
Cotton material: It burns immediately after contact with the fire. It continues to burn after leaving the flame. It has the smell of burning paper and a small amount of grayish white.
Wool material: It burns slowly after ignition. Sometimes it is extinguished after being fired. It has an odor and gray powder.
Nylon cotton material: The contact flame melts and shrinks, it burns very slowly, it extinguishes itself after leaving the fire, special smell, loose and brittle black ash.
Polyester material: Close to the flame melts and shrinks, slowly burns, leaves the flame to continue burning, aromatic smell, very hard black beads.
Acrylic material: close to the flame melting shrinkage, black smoke when burning, specific odor, hard and indefinite lumps.
