In-depth guides on nonwoven production lines, machinery and processes — plus the latest news from Vina Nonwoven.
Zhentai (Changshu Zhentai) is a Chinese group that both produces nonwoven fabric and builds the machinery for it — 40+ needle-punch lines running in-house and 300+ customers worldwide. A full brand profile and machinery range.
Nonwoven fabric is a sheet material made by bonding fibers directly — mechanically, thermally or chemically — without weaving or knitting. This guide covers the definition, the main production technologies, the real machine chain, and applications.
Metal card clothing — metallic wire, saw-tooth wire — is the toothed steel strip wound onto carding cylinders and rollers: what each geometry parameter governs, how it differs from flexible and flat card clothing, how to pick between the nonwoven, cotton-spun and woolen series by fibre, and correct grinding and replacement practice.
BiCo (bicomponent) spunbond spins each filament from two polymers in a core–sheath structure so the fabric bonds itself without adhesives. How it works, how air-through bonding differs from calender bonding and needle punching, and how to choose between the two BiCo lines.
A needle beam is the structural member that carries the needle boards and drives them up and down. How it differs from the board it holds, why rigidity, weight and alignment govern needling precision, the role of lamella segments, wear symptoms, and when a beam must be reworked or replaced.
A drafter stretches the needled web to rebalance the MD:CD strength ratio. How draft ratio works, why the drafter sits between the cross lapper and the finish needle loom, common faults, and selection criteria.
Thermal bonding uses heat — with binder or low-melt fibre where needed — to weld the fibre web into fabric, instead of or alongside needle punching. Calender bonding vs through-air drying, where ironing sits after the needle loom, and when a line actually needs a thermal-bonding section.
Rotor (OE) spinning parts — the rotor, opening roller with its OE card clothing, navel and doffing tube: what each does, how wear shows up as yarn faults, how to choose by fibre type and rotor speed, and correct replacement and maintenance practice.
The circular comb is the toothed comb segment on a comber's combing cylinder that pulls out short fibres, neps and trash: where combing sits between carding and drawing, how it differs from the top comb, what tooth condition does to noil percentage and yarn evenness, plus cleaning and replacement practice.
Fiber opening and blending machines loosen compressed bales and mix raw material into one uniform blend before carding. The sequence from bale opener to pre-opener, blending opener, fine opener and chamber blender — what each machine does, and how to size the stage for your line.
Spunlace (hydroentanglement) bonds the fibre web with high-pressure water jets instead of needles or heat. How it works, what the spunlace head and the water-treatment loop really cost you, what the fabric is used for, and a direct comparison with needle punch.
PSF (polyester staple fibre) is cut-length polyester fibre — the raw material behind nonwoven fabric, polyfill wadding and spun yarn. This guide covers the staple-fibre line, solid vs hollow vs conjugated fibre, the four line types (PSF, PP one-step, ES & sea-island, PET HT/LE) and how to choose.
Nonwoven geotextile is made on a nonwoven line — mostly needle-punch, partly PET spunbond. This guide explains which machines you need and which technology to choose.
There is no fixed price for a nonwoven production line — cost varies with fabric width, capacity, level of automation, technology, new-or-used machines and component origin. This guide explains each factor and how to get an accurate figure for your plant.
To start a nonwoven fabric plant you need a complete line of six machine groups: fiber opening & blending, carding, cross-lapping, needle-punching (or spunbond), calendering and winding. This guide explains what each machine does and where to buy in Vietnam.
You can buy a nonwoven production line in Vietnam through Vina Nonwoven — the distributor for Zhentai, Huayang, Yongxing and White Shark, supplying new machines, inspected used lines, spare parts, and nationwide installation and maintenance.
Choose the technology by your end product: needle-punch for thick, mechanically strong fabric; spunbond for thin, even, high-throughput fabric. This guide compares the two and helps you pick the right one for your plant.
The carding feeder sets fiber-web evenness and GSM stability in needle-punch nonwoven lines: how it works, common faults, and fixes for consistent output.
The needle board drives precision and lifespan in a needle-punch nonwoven line: structure, next-gen composite materials, common failures, and correct maintenance.
5 common needle-punch defects — broken needles, rough surface, tearing, low strength, vibration — causes and fixes for each, for stable quality.
The Cross Lapper drives uniformity and strength in needle-punch nonwoven fabric. Learn how it works, its common faults, and how to optimize it.
Card clothing (carding wire) shapes web quality in needle-punch nonwoven lines: what it does, how each roller is built, what cylinder wire, flat tops and stationary flats are, key specs, mounting, and how to choose and maintain it right.
A complete walkthrough of the 9-step Needle Punching process and core equipment for producing needle-punch nonwoven fabric, from fiber prep to finished roll.
A clear breakdown of Spunbond nonwoven line structure, operating principle, applications, and specs — the foundation for choosing the right equipment and running it efficiently.
