Absorbent cotton material
Bleached Absorbent Cotton for Further Processing
Absorbent cotton material for buyers who need defined fiber length and verified absorption performance before converting, repacking or further processing.
Confirmed quality requirements
Absorbent cotton parameters buyers can review
This table records the requirements confirmed for this absorbent cotton material. It is not being presented as a shared specification for downstream finished products.
| Test item | Requirement |
|---|---|
| Fiber length | Average fiber length ≥10 mm; customizable according to processing needs, up to 38 mm. |
| Foreign fibers | Under microscopy, only typical cotton fibers should be observed; an occasional small number of isolated foreign fibers is permitted. |
| Cotton neps | The number of cotton neps should not exceed the standard reference sample. |
| Water-soluble substances | ≤0.50% |
| pH | 7 |
| Sinking / absorption time | ≤10 s |
| Water absorption capacity | ≥23.0 g/g |
| Ether-soluble substances | ≤0.50% |
| Fluorescence | Only microscopic brownish-purple fluorescence and a small number of yellow particles should be visible; except for a few isolated fibers, strong blue fluorescence should not be observed. |
| Loss on drying | ≤8.0% |
| Sulfated ash | ≤0.40% |
| Surface-active substances | Foam should not cover the entire liquid surface. |
| Extractable coloring substances | The extract should not be darker than the specified reference solution. |
Specification note: Fiber length is the main item available for customization. Supply form, unit weight and packing are confirmed separately during quotation.
Integrated material control
From prepared cotton to buyer confirmation
WJ Cotton manages material preparation within the same production chain, making it easier to connect fiber requirements, absorption performance, sample review and packing decisions.
- Review the required fiber length before sample confirmation.
- Use the confirmed quality requirements as the quotation reference.
- Confirm material form and packing separately for each order.
