1. Knitted fabric: The loop is the smallest basic unit of knitted fabric, and the loop consists of a spatial curve between the loop stem and the extension line. Loops are nested in series to form woven fabric, and the process of yarn forming loops can be carried out horizontally or vertically. Transverse knitting is called weft knitting, and longitudinal knitting is called warp knitting.

2. Woven fabric (woven fabric): It is a woven fabric made by interweaving two groups of mutually perpendicular yarns at a 90-degree angle. Longitudinal yarns are called warp yarns and transverse yarns are called weft yarns. Each intersection of warp and weft is called weave point, which is the smallest basic unit of fabric.

Second, the concept is different.

1, the process of knitting yarns of various raw materials and varieties into loops with knitting needles, and then connecting them into knitted fabrics through a series of sleeves. Knitted fabric has soft texture, good wrinkle resistance and air permeability, high extensibility and elasticity, and is comfortable to wear.

Knitted products can be used not only for clothing and decoration, but also for industry, agriculture, medical care and national defense. Knitting is divided into hand knitting and machine knitting. Handmade knitting needles have a long history, exquisite skills and flexible patterns, which have been widely spread and developed among the people.

2. According to various fabric structures, the process of forming woven fabrics with yarns as warp and weft. It usually consists of three parts: making warp yarns into warp beams, making weft yarns into strips (or bobbins), and weaving and finishing grey cloth.

Weaving is an important part of textile industry production, which can be divided into cotton weaving, wool weaving, silk weaving and hemp weaving according to the types of raw materials used, and its products are collectively called woven fabrics. Woven fabrics have a wide variety and uses (see textiles). According to different application requirements, the suitable yarn raw materials and fabric structure are selected.

Third, the process characteristics are different.

Knitting production can be divided into weft knitting and warp knitting. In weft knitting production, raw materials can be produced directly on the machine after winding. Each yarn is padded on each needle of the weft knitting machine in turn along the weft direction to form a weft knitted fabric.

In warp knitting production, raw materials are wound and warping, yarns are arranged in parallel and wound into warp beams, and then they are produced on the machine. The yarns are unwound from the warp beam, and each yarn is placed on one or at most two needles of the warp knitting machine in the longitudinal direction to form a warp knitted fabric.

2. Weaving usually includes three parts: making warp yarns into warp beams, making weft yarns into sliver (or bobbin), weaving and weaving grey cloth finishing.
