Jacquard Fabric Price Calculator: Reverse Specs & Pricing

🧵 Jacquard Fabric Price Calculation Guide (For Samples with Unknown Yarn Specs)

This operating guide applies when you only have a jacquard fabric sample but don’t know the yarn specifications (warp/weft counts, single/dual yarn structure, etc.). It shows how to use the Jacquard Fabric Price Calculator to intelligently reverse-deduce the fabric specifications and pricing.

🎯 I. Objectives

Determine the warp and weft yarn specifications
Measure the fabric’s GSM and density
Calculate the grey fabric price, dyed price, and FOB export price

🧰 II. Required Tools

Transparent ruler (centimeter scale)
Electronic balance (0.01 g precision)
Scissors, tweezers, and two needles
Yarn count reference cards (counts: 16s–100s)

📏 III. Step 1: Measure Sample Size & GSM (Fig. 1–4)

Fig. 1 Sample appearance — Fig. 1: Sample appearance (complete repeat)

Fig. 2 Length measurement — Fig. 2: Length measurement

Fig. 3 Width measurement — Fig. 3: Width measurement

Fig. 4 Weighing on electronic balance — Fig. 4: Weighing on an electronic balance

Cut a sample that contains a complete pattern repeat.
Measure length and width, e.g.:
- Length: 5.5 cm
- Width: 3.65 cm
Weigh the sample; assume weight is 0.2 g.

Calculate fabric GSM:

GSM = (Weight ÷ Length ÷ Width) × 10,000

Example result: 99 GSM.

🧴 IV. Step 2: Correct to Finished-State GSM

If the sample surface is fuzzy and lacks luster, it indicates a “semi-finished” (un-mercerized) fabric. Deduct about 5% GSM to simulate the finished (mercerized) state.

Finished GSM = Measured GSM ÷ 1.05

Example: 99 ÷ 1.05 ≈ 94 GSM

✨ Differences: Finished vs. Semi-finished

Item	Semi-finished (Un-mercerized)	Finished (After Mercerization)
Surface fuzz	More; rough	Less; smooth
Luster	Dull	Bright; silky
Hand feel	Dry	Soft and smooth
Dyeing effect	Less vivid	Bright and vivid
Weight change	Original value higher	Approx. 5% reduction

🪡 V. Step 3: Count Warp & Weft Repeats (Fig. 9 & 11)

Fig. 8 Counting warp threads with two needles — Fig. 8: Manually counting warp threads one by one using two needles

Fig. 11 Using a transparent ruler to stabilize the fabric — Fig. 11: Holding the fabric with a transparent ruler; one complete repeat is easier to count

Fig. 9 Even weft arrangement — Fig. 9: Even weft arrangement; measuring within 1 cm is sufficient

Cut a section containing a complete repeat.
Remove part of the weft to fully expose the warp.
Count warp ends one by one with needles:
- Warp repeat length: 3.65 cm
- Single yarns: 138 ends
- Double yarns: 4 ends
Count weft density within 1 cm:
- Single yarns: approx. 25 ends/cm

💻 VI. Step 4: Enter Data into the Calculator

Fig. 16 How to fill in the fields — Fig. 16: How to fill in the fields in the calculator

Fig. 19 Estimation results view — Fig. 19: Estimation results interface

Open the Jacquard Fabric Price Calculator and fill in the following parameters in order:

1️⃣ Width

Select the width matching your sample (in inches), e.g., 55/56 inch.

2️⃣ Raw Material Composition

Choose the fabric material from the dropdown (Cotton / Rayon / Tencel / Lyocell, etc.).

3️⃣ Single / Dual (Yarn Structure)

Fill out according to actual observation:

Warp single → Single
Warp double → Dual
Weft single → Single

4️⃣ Finished Product Cycle & In-loop Data

Warp cycle: 3.65 cm
Weft cycle: 1 cm
Warp single: 138 ends
Warp double: 4 ends
Weft single: 25 ends

5️⃣ Real Weight (GSM)

Enter the finished-state GSM corrected in Step 2: 94 GSM.

6️⃣ Precision

“Pull out one single yarn from both warp and weft, hold both taut and compare. Choose based on whether a visible thickness difference exists.”

Unlimited: show all results
Not obvious: warp ≈ weft in thickness (recommended)
Warp thicker / Weft thicker: choose based on visual judgment

7️⃣ Click “Estimation Now”

The system will automatically generate multiple yarn combinations (e.g., J40 + J60/2 * J40).

👁️‍🗨️ VII. Step 5: Visually Filter the Closest Combinations

Fig. 25 Pull out double yarns for comparison — Fig. 25: Pull out double yarns for visual comparison as a reference

Fig. 27 Delete unmatched double-yarn combinations — Fig. 27: Delete obviously unmatched double-yarn combinations and keep the matches

Tip: After selecting the matching combination, click “Calculation Results” to view the final output page.

Use standard yarn cards (16s–100s) to compare the double yarns pulled from the sample.
Eliminate combinations that are clearly too coarse or too fine.
Keep the 2–3 closest matching results.

📊 VIII. Step 6: Calculate & Output (Fig. 27 & 30)

Click Calculation Results.
The system will generate the following results:

Fig. 30 Final results view after clicking Calculation Results — Fig. 30: After selecting a matching combination, click “Calculation Results” to view the final output

Specification: J40 + J32/2*J40
Density: 98 × 63
Width: 55/56
GSM: 95
Grey Fabric Price/M: ¥8.28
Dyed Product Price/M: ¥12.35
FOB Price/Y: ¥1.39

🤖 IX. Notes on the AI Logic

Based on the entered repeat data, yarn structure, GSM, and precision filter, the system matches against its database to reverse-deduce reasonable yarn combinations and price ranges.

Finished-state judgment: if the surface is smooth and clean → Finished; otherwise → Semi-finished (apply GSM × 0.95).

Filtering logic:

If warp ≈ weft thickness → Not obvious
If warp thicker         → Warp thicker
If weft thicker         → Weft thicker

Output priority: Highest precision → Closest GSM → Material consistency.

✅ XI. Summary

By following this workflow, even without known weaving data, you can quickly obtain via measurements and system calculations:

Yarn structure (warp & weft specifications)
Density and GSM
Grey price, dyed price, and FOB export price

This process is especially useful for sample development, cost estimation, and client quotation analysis. Combined with AI assistance, it enables fast reverse calculation and automatic pricing for fabrics.
