Why This Garment

Name: China PP Cleanroom Garment with Hook & Loop Fastener Manufacturers, Suppliers and Factory - Weston
Brand: Weston
SKU: 308310250

Standard cleanroom suits often compromise between comfort and contamination control. This garment eliminates that trade-off. The hook & loop fastener at the collar closes securely without metal hardware, the side elastic panels allow unrestricted movement during long shifts, and the conductive fiber woven into the fabric continuously dissipates static charge - not just when grounded.

Cleanroom garments specific parts

Five Reasons Facilities Specify This Garment

Integrated ESD protection, not a surface coating

The 1% conductive fiber is knitted into the 100D ripstop base fabric. Unlike topical antistatic treatments that wash out over time, this protection does not degrade with laundering cycles.

Hook & loop collar with zero metal contamination risk

Metal snaps and buttons are a contamination liability in pharmaceutical and photovoltaic lines. The hook & loop fastener seals the collar gap without introducing hard particles or corrosion risk.

Two-piece split design for practical gowning

The jacket and trousers are separate garments. This matters operationally: technicians entering partial clean zones can don the jacket alone; laundry batches can be separated by wear frequency; replacement of a worn jacket does not retire a functional pair of trousers.

Side elastic panels where mobility is actually needed

Elastic inserts at both sides of the jacket allow full arm extension and torso rotation. Operators working at laminar flow benches or overhead equipment report less fatigue compared to rigid-seam alternatives.

Compliant with GB 12014-2019 - testable, auditable

The garment is manufactured to the current Chinese national standard for electrostatic protective clothing. This simplifies vendor qualification, audit documentation, and incoming inspection protocols.

Test Report Data

Test Parameter	Result
Charge density	1.2 μC/m²
Triboelectric voltage	< 500 V
Surface resistance	10⁶ – 10¹⁰ Ω
Test standard	GB 12014-2019

Note on surface resistance range: 10⁶ Ω is the lower bound for controlled static dissipation; 10¹⁰ Ω is the upper limit for antistatic classification. This range ensures the garment dissipates charge without creating a grounding hazard in mixed-voltage environments.

Application Scenarios

1. Biopharmaceutical Cleanrooms (GMP Grade C/D)

In GMP C and D environments, gowning protocols are audited and garment integrity is a regulatory requirement, not a preference. The hook & loop collar closure allows visual confirmation of a full seal during gowning checks - a detail that matters when a line supervisor is walking the floor before a batch release.

Practical example: A contract manufacturing organization running injectable fill-finish in a Grade D corridor uses this garment for all production staff outside the Grade B core. The two-piece format allows laundry to be sorted by zone - jackets from personnel entering Grade C antechambers are laundered separately from those worn only in Grade D corridors, extending service life and reducing cross-contamination risk between zones.

2. Medical Device Assembly (ISO Class 7 / Class 8)

Orthopedic implant and surgical instrument manufacturers frequently operate in ISO Class 7 spaces where both particulate and ESD control matter - an ungrounded operator touching a PCBA-embedded device can cause latent failures that only appear post-sterilization.
Practical example: A Tier 1 medical device supplier assembling electrosurgical generators uses this garment in conjunction with grounded wrist straps and ESD flooring. The conductive fiber in the suit completes the body-to-ground path through the wrist strap, reducing human-body voltage to below the 100V threshold required by IEC 61340-5-1.

3. Photovoltaic Cell Production

Solar cell fabrication is sensitive to both particle contamination and electrostatic discharge. A single ESD event during wafer handling can create micro-cracks invisible under standard inspection but measurable as power output loss after lamination.

Practical example: A photovoltaic module manufacturer running monocrystalline silicon cell lines specifies this garment for all personnel entering the diffusion and screen-printing zones. The < 500V triboelectric voltage rating ensures that the garment itself does not become a charge generator when operators move between process stations.

Frequently Asked Questions

Q: Does the hook & loop fastener generate particles that could contaminate the clean environment?

A: Hook & loop fasteners in cleanroom-grade garments use low-linting, tightly woven nylon tape on both the hook and loop sides. The fastener is sewn into the collar facing, so the hook element is not exposed to the clean side of the garment. When the collar is closed, both surfaces are sealed against each other. This is specifically why hook & loop is preferred over snap buttons in pharmaceutical environments - there are no metal components to corrode or shed metallic particles.

Q: Can this garment be autoclaved or gamma-irradiated for sterile gowning applications?

A: This garment is not designed for autoclave sterilization. The polyester base fabric can withstand repeated industrial laundering and low-temperature sterilization processes. For Grade A/B aseptic applications requiring pre-sterilized gowning, a dedicated sterile-packaged suit is the correct specification. This garment is rated for Grade C/D and ISO Class 7–8 - controlled but non-sterile environments.

Q: What is the expected service life, and when should the garment be retired?

A: Service life depends on laundering frequency and handling. The conductive fiber is structurally integrated, so antistatic performance does not degrade from washing alone. The recommended retirement trigger is surface resistance drift: if a post-laundry resistance check returns a value above 10¹⁰ Ω, the garment should be removed from service. Most facilities on a twice-weekly laundering cycle find garments remain within specification for 50–80 wash cycles.

Q: Does the same garment cover both ISO Class 7 and ISO Class 8 environments?

A: Yes. ISO Class 7 (10,000-class) and ISO Class 8 (100,000-class) are both within the garment's validated performance range. The distinction matters for your gowning procedure documentation, not for the garment specification itself. A single SKU covers both grades, which simplifies inventory management for facilities that operate both classes under one roof.

Q: Is this garment available in ESD-safe colors only, or can we specify color for zone identification?

A: Seven standard colors are available: White, Blue, Pink, Yellow, Green, Grey, and Cyan. Many facilities use color-coding to differentiate cleanroom zones or departments - for example, white for ISO Class 7 spaces and blue for ISO Class 8 corridors. Color selection does not affect the antistatic performance of the conductive fiber network. Contact Weston for custom color runs subject to minimum order quantities.
