The Uncompromising Standard: Our Quality Control Process for Flawless Wool & Cashmere Coats

At Yangchenghu Cashmere, we believe that true luxury is defined by uncompromising quality. A cashmere or wool coat is not merely a garment; it is an investment, a statement of enduring elegance, and a promise of warmth. To uphold this promise, we have instituted a rigorous, multi-stage Quality Control (QC) process that scrutinizes every aspect of production, from the raw fiber to the final stitch.

Our commitment to flawlessness ensures that when you choose a Yangchenghu Cashmere coat, you are receiving a product that embodies the pinnacle of textile craftsmanship and material excellence.

Stage 1: Raw Material Purity and Excellence

The foundation of a superior coat is the fiber itself. Our QC process begins long before the first thread is spun, focusing on the integrity and quality of the raw wool and cashmere.

Fiber Sourcing and Grading

We exclusively source Grade A cashmere, characterized by its exceptional fineness and length. The industry standard for high-quality cashmere dictates a fiber diameter typically between 14 and 15.5 micrometers (µm) and a fiber length exceeding 30 millimeters (mm) [1]. This combination of fineness and length is crucial for creating a fabric that is incredibly soft, lightweight, and resistant to excessive pilling.

Purity Verification

To guarantee authenticity, we conduct stringent purity tests. While a simple "feel test" can indicate softness, our process includes advanced laboratory analysis, such as microscopy or DNA testing, to confirm the exact percentage of cashmere and wool, ensuring our coats are never blended with inferior fibers [2].

Stage 2: Fabric Weaving and Inspection

Once the raw fibers are approved, they are spun into yarn and woven into the luxurious fabric that forms the body of the coat. This stage involves meticulous checks to ensure the fabric's structural integrity and aesthetic perfection.

Structural Integrity Check

The fabric must possess the correct density and weight (GSM - Grams per Square Meter) to achieve the desired drape and warmth. We inspect the weave structure to ensure consistency, looking for any irregularities, slubs, or weak points that could compromise the coat's longevity.

Color Fastness and Dimensional Stability

We perform tests for color fastness to ensure the rich, deep hues of our coats will not fade or bleed, even after professional cleaning. Furthermore, a dimensional stability test is conducted to predict and prevent excessive shrinkage or stretching, guaranteeing the coat maintains its intended size and shape over time [3].

Stage 3: Precision Tailoring and Craftsmanship

The transition from fabric to finished coat is where the artistry of tailoring meets our technical QC standards. This is the most labor-intensive stage, requiring a keen eye for detail.

Cutting Accuracy

Each coat pattern piece is cut with laser-like precision. We verify that the grain line of the fabric is perfectly aligned with the pattern, which is essential for the coat's proper drape and fit. Misaligned cuts can lead to twisting or sagging in the final garment.

Stitching and Seam Quality

The quality of the stitching is a hallmark of a luxury coat. Our inspectors meticulously examine every seam, ensuring:

•Evenness and Density: Stitches are uniform in length and density, providing maximum strength.

•Flat Seams: Seams are pressed and finished flat, preventing bulkiness and ensuring a smooth interior and exterior finish [4].

•Thread Matching: The thread color and thickness are perfectly matched to the fabric, making the seams virtually invisible.

Component and Hardware Check

All secondary components, including linings, interlinings, buttons, and zippers, are inspected. Buttons must be securely attached, and any hardware must be smooth, functional, and free of defects. For our signature coats, we ensure the lining is sewn with a slight ease to allow for comfortable movement and prevent stress on the outer fabric.

Stage 4: Final Inspection and Packaging

The final stage is a comprehensive, top-to-bottom review of the finished garment before it is approved for shipment.

The 10-Point Garment Audit

Every coat undergoes a final 10-point audit, which includes:

1.Overall Appearance: Checking for any visible blemishes, marks, or fabric defects.

2.Sizing and Fit: Measuring against the master specification to confirm accurate sizing.

3.Symmetry: Ensuring pockets, lapels, and sleeves are perfectly symmetrical.

4.Pressing and Finishing: Verifying the coat is perfectly pressed and free of wrinkles.

5.Labeling: Confirming the care and content labels are correct and securely sewn.

6.Odor Check: Ensuring the coat is free of any chemical or manufacturing odors.

7.Button and Buttonhole Functionality: Testing all closures for ease of use.

8.Lining Integrity: Checking the lining for tears or loose seams.

9.Pockets: Ensuring pockets are fully sewn and functional.

10.Loose Threads: Trimming all loose threads to present a clean, finished look.

Protective Packaging

Finally, the coat is carefully folded, protected with tissue paper, and placed in its protective garment bag. This ensures that the coat arrives at your door in the same pristine condition it left our workshop.
