A Raschel machine (100) comprises a plurality of first guide needles (110) arranged along a first direction for guiding warp threads (210), a plurality of second guide needles (150) arranged along the first direction for guiding weft threads (220) and a plurality of needles (180) arranged along the first direction for creating interlocked loops formed by threads, whereby the warp threads (210) are created. The first guide needles (110) are held by a first needle bar (120), the second guide needles (150) are held by a second needle bar (160), and the second needle bar (160) is moved back and forth between two respective neighbouring first guide needles (110). The space between neighbouring first guide needles (110) is greater than 25.4 m (1 inch).

The invention relates to a plastic mesh having a plurality of chains extending parallel to one another in a longitudinal direction, which plastic mesh has a plurality of groups of chains (2) adjacent to one another, which are in each case formed of at least two chains (2a, 2b). The groups of chains (2) have a greater spacing relative to one another or also relative to a further individual chain (1) than the chains (2a, 2b) within a group of chains (2). A thread (3) runs in a zigzag between two adjacent groups of chains (2) or also between one group of chains (2) and an individual chain (1) and connects the chains (1) or groups of chains (2).

The present invention provides a mop cleaning cloth and a method for manufacturing the same. The mop cleaning cloth comprises, sequentially from bottom to top, a base cloth layer, a water-absorption layer and a dirt removal layer. The dirt removal layer is formed by high terry fabrics and low terry fabrics. The ratio of the terry height of the high terry fabrics to the terry height of the low terry fabrics is 1.1-5:1. The high terry fabrics have a terry height of 2-20 mm and low terry fabrics have a terry height of 1-10 mm. The water-absorption layer is formed by a water-absorption fabric made from water-absorption fibers. The base cloth layer is formed by a terry fabric. The manufacturing method is simple, and the mop cleaning cloth is easy to manufacture and has the advantages of being small in resistance, high in water absorptivity and dirt collection and removal capacity, and the like.

A yarn tension control device of knitting machines is revealed. A plurality of yarn tension control devices is disposed on a knitting machine for control of warp yarns while weaving the warp yarns to produce fabrics. The warp yarns can be metal yarns. The metal yarns on a yarn disc are passed through a guide holder, bars for drop wires, and drop wires and then entered steel healds and reeds. Thus a constant yarn tension over the warp yarns is ensured by the yarn tension control devices during a weaving process of weft yarns. The tension of the metal yarns is the same with the tension of textile yarns. Thereby a stable yarn tension over the warp yarns gives uniform fabric appearance.

Disclosed are a tension adjustment method of a warp knitting variable-speed and uniform-tension yarn feeding device, and a weaving method. The device includes warp beams, connecting rod frames, a guide bar, a looping mechanism and a drawing and rolling-up mechanism, where the connecting rod frames are connected to yarn winding wheels and yarn guide plates, yarns are wound on the warp beams, and the yarn winding wheels are positioned between the warp beams and the guide bar; each of the yarn winding wheels includes a yarn inlet, a yarn winding shaft and a yarn outlet. According to the present disclosure, the tension produced in a yarn feeding process is actively adjusted by the variable-speed tension yarn winding wheels to make up tension error caused by looping; and the present disclosure is capable of compensating in time, does not easily break the yarns, is high in knitting efficiency and quality.
