SW-864X Cleaning Dust Free Polyester Swab

Product Overview

The SW-864X is a dust-free cleaning polyester swab with a double-layer polyester fabric head on a green polypropylene handle with a notched break point, engineered for high-cleanliness surface wiping, contamination sampling, and analytical surface analysis tasks in microelectronics, semiconductor, optoelectronics, and biomedical manufacturing environments where the swab's own contribution to surface contamination — particles, ionic residue, and chemical extractables — must be controlled to documented process standards rather than general cleanroom practice.

The swab head is constructed from double-layer polyester fabric — two layers of knitted polyester bonded together — which increases fiber contact density relative to single-layer heads of equivalent thickness, improving the capture rate of fine particulates and chemical residues from the substrate surface during the wiping pass. The double-layer fabric is known for its non-shedding properties and strong adsorption capability, enabling effective collection of minute particles and chemical residues from flat substrate surfaces. Head dimensions are 25mm in length, 13.5mm in width, and 2.8mm in thickness, with a flat, hard-core, large-headed profile suited to wiping larger surface zones in a minimum number of strokes.

Construction Details & Low-Contamination Design

The double-layer polyester head is bonded to the handle through a heat-shrinking process that eliminates adhesive entirely from the swab construction — preventing adhesive dissolution into cleaning solvents and subsequent deposition of adhesive-derived ionic or organic contamination onto critical substrate surfaces. The fabric edges are sealed using edge-banding technology that prevents fiber release from the head perimeter during use, addressing the contamination risk that unsealed polyester fabric edges present in high-cleanliness applications. Together, the adhesive-free thermal bonding and the edge-sealed perimeter ensure that the SW-864X itself introduces no new contamination sources beyond the polyester fiber's inherent low particle and low ionic content.

The green polypropylene handle provides visual identification in cleanroom environments and incorporates a notched break point for handle length adjustment — a feature that allows the operator to shorten the handle for confined-space access without introducing cut-end contamination, since the notch produces a clean break rather than a fractured or splintered handle end. The handle provides low particulate generation and is free from adhesives. Handle dimensions: 125mm total length, 6.6mm width, 2.4mm thickness. Packaged 100 pieces per bag, 50 bags per carton.

Industry Applications & Use Scenarios

The SW-864X is used in microelectronics manufacturing, semiconductor assembly, optoelectronics production, biomedical device manufacturing, and controlled laboratory environments where both cleaning performance and documented contamination control of the swab tool itself are process requirements. Specific application scenarios include surface cleaning and contamination sampling on semiconductor wafer substrates, wiping optical component surfaces in optoelectronics assembly before alignment verification, cleaning display substrate active zones in flat-panel manufacturing quality inspection workflows, performing surface analysis sampling in biomedical device production environments, and cleaning large flat precision instrument surfaces in analytical laboratory operations. The notched handle break point makes it particularly useful for field maintenance operations where handle length must be adjusted on-site to match equipment access geometry without introducing new contamination from handle modification. The combination of double-layer fabric, edge sealing, adhesive-free thermal bonding, and low-particulate polypropylene handle positions the SW-864X as the highest-specification general-purpose wide-head polyester swab in this product series.
