Water jet looms are mainly used for weaving hydrophobic synthetic fibers such as polyester and nylon. As a highly hydrophilic viscose filament, people are used to thinking that it cannot be produced by a water jet loom.

Water jet looms have created a series of problems in the manufacture of hydrophilic fabrics. For example, weft breaks frequently occur during weaving, and the car cannot be driven at all; due to the high amount of yarn hairiness, the weft yarns are easy to stick to each other during weft storage, and the ordinary mechanical weft storage system is prone to entanglement during weft insertion, which makes it difficult to unwind.

Due to the strong hygroscopicity of hydrophilic fibers, the self-weight increases significantly after absorbing water, and the flight resistance increases, resulting in insufficient weft injection; when we start weaving, the loom stops more idle mainly because the hank yarn has many hairiness, easy to stick, and ordinary touch The finger weft detection system is prone to malfunction between the two contact fingers, causing the loom to stop idly; when starting weaving, there are many parking gears because the viscose absorbs enough water when parking, and the self-expansion volume increases. At the first weft, the moisture of the previous weft cannot be completely squeezed out, so there is a tight gap; due to the sufficient water absorption of the viscose, it is difficult to dry the grey silk, so that the grey fabric cannot be fully dried.
