Challenges in Cutting Rayon and Textile Processing

To dear with the "Soft Yet Abrasive" Materials:

Rayon fibers themselves are soft, but the delustering agents added (such as titanium dioxide) have very high hardness. While the blade cuts the fibers at high speed, it is also constantly rubbing against these hard particles, similar to cutting fabric mixed with fine sand using a blade, which leads to rapid wear of the cutting edge.

To control the Impact of "Heat":

Chemical fibers like rayon are sensitive to temperature. Although textile cutting speeds are extremely fast and contact time is short, worn and dulled tools generate more frictional heat, which may cause local melting at the fiber cut edges, resulting in hard knots or drawn filaments that affect subsequent processes.

Another is to withstand the "Unstable" Cutting Forces:

A bundle of rayon consists of thousands of individual filaments, with microscopic inconsistencies in density and uniformity. During cutting, the tool experiences uneven forces with slight impacts. Tungsten carbide hard alloys have high hardness but relatively poor impact toughness, making them prone to microscopic chipping under such conditions.

Enduring "High and Fluctuating" Raw Material Costs:

Tungsten carbide, as a strategic resource, has prices heavily influenced by policies and market factors. For textile blades, which require strict cost control, significant fluctuations in raw material prices severely squeeze manufacturers' profit margins and pose challenges to product pricing and supply chain stability. T

he pain points of tungsten carbide knives used in the rayon textile industry are rooted in the complex interactions between the chemical and physical properties of the fibers, the inherent characteristics of the tool materials, and macroeconomic cost pressures.
