Reinforced Nonwoven Tape
Choose reinforced nonwoven tape by grade and trial. The fibrous wrap is strengthened with yarn or thread so it can carry process loads without relying on basis weight alone. Balance tensile and elongation data against thickness, radial build, flexibility and line handling, then confirm the chosen grade on the intended cable construction.

What Reinforcement Changes in Non Woven Cable Tape
A normal nonwoven develops its properties from fibers, bonding and basis weight. A reinforced construction adds a load-carrying element, such as high-strength yarn or thread, within or alongside the fibrous web. This can change how force is distributed during payoff, guiding and wrapping. It does not create a universal strength advantage under every test direction or cable condition.
The reinforcement layout matters. Longitudinal threads may support the machine direction, while the web still supplies coverage, conformity and separation. Buyers should therefore ask how the reinforcement is arranged, which direction was tested, the specimen width and whether the stated result is breaking force per unit width or another value. A single word such as “reinforced” cannot replace that evidence.
The Chaowang non-woven cable tape range separates reinforced, binding, flame-retardant and semi-conductive families. That family structure helps define the shortlist, while the cable drawing must still identify the exact layer duty.

Read CW-3 Grade Data as Complete Rows
Jiangsu Chaowang New Material describes CW-3 Reinforced Lightweight Non Woven Tape as high-strength polyester industrial yarn, high-strength thread and adhesive. Its public table lists two grades. GQ-WF10 is shown at 0.10 ± 0.02 mm, 70 ± 10 g/m², at least 40 N/cm tensile strength and at least 60% elongation. GQ-WF16 is shown at 0.16 ± 0.02 mm, 100 ± 10 g/m², at least 50 N/cm and at least 80% elongation.
Keep each row together. Do not combine the thinner grade's build with the thicker grade's strength or elongation. Also request the current datasheet and test methods before comparing CW-3 with another supplier. ISO 9073-1:2023 covers mass per unit area, ISO 9073-2 determines nonwoven thickness under specified pressure, and ISO 9073-3:2023 covers strip tensile strength and elongation. Results are comparable only when the procedures, directions and units align.
The public CW-3 page also contains thermal fields, including a shrinkage row whose inequality should be confirmed before use. This article does not reinterpret that symbol or turn it into an acceptance limit. Ask for the current controlled document when temperature performance is part of the purchase specification.
Match Reinforced Non Woven Tape for Cable to the Layer
The official CW-3 page positions the family for power, mining, rubber-sheathed, marine, high-temperature and relatively flexible cables. This is an application shortlist, not proof that one grade fits every construction. Identify whether the tape must bind components, separate layers, stabilize a flexible core or withstand a demanding wrapping process, then set only the properties needed for that duty.
- Mechanical demand: define the expected process load, direction and acceptable break frequency.
- Radial build: check nominal thickness, tolerance, overlap and the effect of double thickness under the next layer.
- Flexibility: inspect whether reinforcement creates ridges, local stiffness or poor conformity on the actual core diameter.
- Functional boundary: do not infer conductivity, flame performance or water swelling from reinforcement alone.
For ordinary core binding, compare the drawing with CW-1 non-woven binding tape rather than assuming CW-3 is automatically better. If longitudinal water control is required, review a dedicated material such as CW-5 water-blocking tape. The broader non woven tape function guide explains how these families remain separate.
Qualify Roll Format and Line Handling Before Approval
Material data cannot show whether a converted roll will run cleanly on the intended equipment. State slit width and tolerance, core inside diameter, roll outside diameter or length, winding orientation, joint policy, edge condition and packaging. Condition the trial material as agreed, identify the cable construction and record the starting settings.
- Inspect the roll for telescoping, crushed edges, contamination, loose winding or visible reinforcement defects.
- Thread the established tape path and observe payoff, dancer stability, guide contact and tracking at controlled speed.
- Check the applied wrap for flat entry, wrinkles, edge lift, thread exposure, overlap variation and local ridges.
- Measure the resulting diameter and examine the next wrapping or extrusion operation for displacement or surface marking.
- Retain settings and samples from start-up, steady production and relevant speed or reel transitions.

Frequently Asked Questions
Is reinforced nonwoven tape always stronger than plain nonwoven tape?
No universal comparison is valid without matched test methods, specimen directions, widths and conditioning. Reinforcement can carry load in a designed direction, but the result also depends on web construction, bonding, thickness and yarn layout. Compare complete grade data and confirm performance on the proposed cable line.
Can CW-3 directly replace CW-1 binding tape?
Not automatically. CW-1 and CW-3 are separately named product families with different published constructions and grade tables. A substitution can change thickness, elongation, surface behavior and radial build. Review the layer duty and roll format, then conduct a controlled trial before approving the change.
Does reinforced non woven tape provide electrical insulation?
Reinforcement alone does not establish an electrical classification. The CW-3 public table does not publish the resistance or dielectric evidence needed to make that claim. If the cable drawing includes an electrical requirement, request grade-specific data, the applicable test method and the project's acceptance limit separately.
Should the grade with higher tensile strength always be selected?
No. Higher tensile data may come with different thickness, mass, elongation or stiffness. Excess build can affect overlap ridges and downstream dimensions, while a less conformable wrap may not suit a small or flexible core. Choose the lowest-risk complete grade that meets the defined layer duty.
How should CW-3 thermal data be specified?
Use the current controlled datasheet and an agreed test method. The public page includes thermal fields, but one shrinkage inequality requires confirmation before it becomes a purchase limit. State the actual exposure during processing and service, then define the property, temperature, duration, direction and acceptance criterion.
What should accompany a CW-3 sample request?
Send the cable layer drawing, core diameter, application method, required tape width and thickness, roll dimensions, line-speed range, expected process load, adjacent materials and relevant test methods. Request a representative grade and converted roll so the trial reflects the intended production condition.
To review reinforced non woven tape for cable, send Jiangsu Chaowang New Material the layer drawing, required physical data, converted-roll dimensions and planned trial conditions. Request the current CW-3 datasheet and a representative sample before production approval.
