BQCIS

Scientific Verification of Fiber Identity and Blend Ratio

BQCIS laboratories provide quantitative and qualitative fiber analysis using advanced microscopy, infrared spectroscopy (FTIR), and chemical solubility methods. Our testing determines accurate fiber composition and blend proportions for both natural and synthetic materials.

The analysis supports compliance with global labeling regulations including EU Regulation (1007/2011), ASTM D629, ISO 1833, and national textile labeling laws, ensuring accurate consumer information and fair trade.

Fiber verification is essential for import/export assurance, supplier validation, and brand protection — preventing substitution, mislabeling, or fraud in textile and apparel supply chains.

Key Activities in Fiber Composition Analysis

Microscopic Fiber Identification

Determine fiber morphology and structure using polarized and comparison microscopy.

FTIR & Spectroscopic Analysis

Identify polymeric composition and verify synthetic blends using Fourier Transform Infrared Spectroscopy.

Chemical Solubility & Dissolution Tests

Quantify fiber blends (cotton/polyester, wool/nylon, etc.) using standardized solubility methods.

Thermal Analysis (TGA/DSC)

Assess material degradation points and distinguish thermoplastic from natural fibers.

Label Verification Audits

Cross-check garment labeling claims with laboratory-measured composition data.

Contaminant & Foreign Fiber Detection

Detect and quantify non-declared fibers, impurities, or recycled material blends.

Supplier Batch Verification

Routine testing of textile lots for OEM and export quality control certification.

Global Regulatory Reporting

Issue compliant fiber content reports recognized by international regulatory bodies.

Quantitative Analysis of Blends

Accurately determine the percentage of each fiber type in a blended fabric for labeling accuracy.

Key Benefits of Fiber Content Analysis

Label Compliance

Label Accuracy & Compliance

Ensures declared fiber content meets national and international labeling regulations.

Quality Assurance

Quality Assurance

Confirms product quality and authenticity at every production or import stage.

Risk Reduction

Risk Reduction

Prevents penalties, recalls, and brand reputation risks due to fiber misrepresentation.

Supply Chain Transparency

Supply Chain Transparency

Provides traceable verification of fiber origin and content through third-party certification.

Success Story

Fiber Composition Verification for Export Garment Manufacturer

The Challenge:

An apparel exporter required independent verification of fiber composition to meet EU Regulation (1007/2011) for blended fabrics.

Our Solution:

BQCIS performed FTIR spectroscopy and solubility testing, confirming correct blend ratios and eliminating labeling errors.

The Result:

Garments cleared customs with zero non-compliance flags, strengthening supplier reliability and export continuity.
