Knitting fabric manufacturers _ warp knitted fabrics and production process

The warp-knitted fabric is formed by arranging one or several sets of parallelly placed yarns on the parallelly placed knitting needles in the longitudinal direction. The warp knitting production process generally includes the following materials into the factory, material inspection, warping, weaving, blank inspection, weighing, printing, semi-product storage, dyeing and finishing, shaping, product inspection, rolling, weighing, packaging, product people Library.

1. The base unit of warp knitted fabric

The base unit of the warp knit fabric is a coil and an extension wire. Weaving different warp knitting organizations has different coils and extension lines. The part that forms the loop and the sleeves are joined into the fabric is that there are generally three methods for coiling bears: silent coils, open coils, and heavy coils. The part where the coil is connected and elongated, and the part without the arc of the shape is the extension line. Various types of warp knit fabrics occur because coils and extension lines undergo different configuration changes during the weaving process.

Warp knit fabric base structure and production process

Second, the basic organization of warp knitted fabric

The base structure of warp knitted fabrics is the root of all warp knitting.

1. Chain organization

In the knitting process, the yarn guiding needle guide yarn is always laid on the same knitting needle, which constitutes a chain structure. The coils whose longitudinal rows are adjacent to each other are not coupled.

The chain organization generally needs to cooperate with other organizations to weave and produce a straight stripe effect, while other organizations have a lateral joint effect and arrive at the purpose of fabricating the chain fabric. The chain organization has the following characteristics:

(1) Because there is no contact between the wales in the chain organization. Therefore, there will be no curling in the horizontal direction.

 (2) The longitudinal extent of the chain structure depends on the elasticity of the material (yarn) and the great extensibility of the material.

(3) The chaining organization is often used for warp knitted fabrics with stable and extensible requirements.

(4) The lateral extensibility is generally small and the size depends on other organizational characteristics of the longitudinal link of the linked braided structure.

2. Jingping organization

The flattened needle tissue of the flat tissue and the weft knitting is the simplest and most basic organization in the warp knitting organization. All of the coil portions in the warp structure have a one-way extension line, that is, the lead and lead extension portions of the coil are on one side of the coil. Commonly used flat structure diagrams, use silent coils.

The characteristics of the peace organization are:

(1) The length of the extension line in the flat structure is long and the structure is strong, opaque and thick.

(2) It is similar to the weft-knitted weft needle structure, which is prone to curling but has less dispersibility.

3. Satin

The fabric of the original semi-shutter yarn in the 111-page order in which three or more knitting needles are looped into a loop is called a satin weave.

When weaving the satin weave, the yarn progressively advances the yarn in at least two consecutive courses in one direction and then performs the same yarn movement in the opposite direction. Through a combination of different mat movements. Can form a more messy and modified more speckled pictures.

4. Heavy organization

The structure of the coils on the two adjacent longitudinal rows of each warp yarn on the same course is a heavy warp structure, that is, at the time of weaving, the yarn is woven together on the two needles to weave the warp-weave fabric. The distinguishing feature is that each warp yarn is required to be placed on two knitting needles at a time.

5. Double-sided warp organization

2. The double - sided warp knitting fabric is woven on a double needle bed warp knitting machine. Also known as a double needle bed warp knitting structure, it is woven into a loop by knitting needles which are respectively placed on the front and rear needle beds by warp yarns to form a double-sided warp knitted fabric.
