Problems & Solutions
Streaks and Bars in Wool Fabric
What causes lengthwise streaks or crosswise bars?
01 · Define the buyer decision
What must be decided before you compare suppliers
The phrase wool fabric streaks can describe several constructions, finish levels or commercial assumptions. Use the following three gates to keep samples and quotations tied to the same end use.
Direction of the mark
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Repeating interval
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
Visibility before and after finish
Write the intended result in the brief and ask how the proposed construction, blend or process will reproduce it in bulk.
02 · Make the request comparable
RFQ and specification checklist
Put each point in the written enquiry. Ask whether a quoted figure is a nominal target, a guaranteed range or a result from the actual production-representative sample.
Photographic and physical reference
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Roll map
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Yarn and loom lot records
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Lighting and nap direction
State the method, unit, tolerance or physical reference where relevant. Record who approves it and at which sample or bulk stage.
Include the garment, selling market, care route, order quantity by colour, delivery location and target schedule. A technically precise fabric can still be wrong for the commercial program.
03 · Control the approval path
A four-stage working method
- 01
Quarantine and map the affected lot
Keep the reference, result and approval owner in the order file so the next stage uses the same definition of acceptable.
- 02
Reproduce the issue with the agreed method
Keep the reference, result and approval owner in the order file so the next stage uses the same definition of acceptable.
- 03
Trace material and process records
Keep the reference, result and approval owner in the order file so the next stage uses the same definition of acceptable.
- 04
Trial the correction and retest side effects
Keep the reference, result and approval owner in the order file so the next stage uses the same definition of acceptable.
04 · Prevent predictable failure
Common risks and practical corrections
Corrective finishing hides the issue temporarily
Find the source.
Shade and structural bars are confused
Inspect texture and colour separately.
Mixed yarn lots create recurring bands
Strengthen lot control.

Frequently asked questions
Quick answers buyers can reuse
01What causes lengthwise streaks or crosswise bars?+
Possible causes include yarn count, twist, blend or shade variation, loom settings and uneven finishing. Direction and repetition help identify the source, so document defects before extra processing changes their appearance.
02What should an RFQ include for wool fabric streaks?+
Include Photographic and physical reference, Roll map, Yarn and loom lot records, Lighting and nap direction. State the test methods, tolerance, quantity by colour and intended garment so quotations are comparable.
03What should buyers check before bulk approval?+
Corrective finishing hides the issue temporarily: Find the source. Shade and structural bars are confused: Inspect texture and colour separately. Mixed yarn lots create recurring bands: Strengthen lot control.
