Ultralight 400T Downproof Nylon Fabric (Matte) – CC-1508

Ultralight 400T Matte Downproof Nylon Fabric – CC-1508

400T downproof nylon fabric CC-1508 is developed for insulated products where the shell or lining should contribute as little weight as possible. At only 36 GSM, it creates a light protective layer around down or synthetic insulation without making a packable jacket feel unnecessarily bulky.

The fabric is woven from 100% nylon using fine 20D × 20D yarns in a compact plain-weave construction. Matte nylon gives it a more restrained appearance than bright filament shells, while water-repellent and calendered downproof finishing prepare the material for lightweight padded garments, sleeping bags and insulated accessories.

Why Choose 400T Downproof Nylon Fabric?

A successful insulated garment needs more than warm filling. Its surrounding fabric must help contain fine fibres, accept quilting stitches and remain comfortable when worn close to other layers.

The 400T construction creates a fine, closely woven surface. Calendering further compresses the fabric between heated rollers, reducing the spaces through which down or synthetic fibres may escape. This allows CC-1508 to remain extremely light while supporting the containment requirements of packable insulated products.

For buyers searching for 36 GSM matte nylon fabric for ultralight down jackets, CC-1508 offers a useful combination of low weight, compact construction and a clean visual character. It can be considered for both visible outer panels and lightweight inner linings, depending on the required strength, colour and hand feel.

A Matte Surface with Calendered Character

“Matte” describes the low-gloss direction of the nylon yarn and finished appearance. Calendering smooths and compresses the fabric, so one side may display a slightly different surface reflection or hand feel.

The final effect should be checked under natural and artificial light, particularly in dark colours where pressure marks or surface changes may become more visible. A larger cutting also provides a better impression of the fabric than a small swatch.

This 20D calendered nylon shell for packable insulated clothing can support minimalist garment designs because it has no visible ripstop grid. Quilting pattern, colour and panel construction therefore become the main visual elements.

Where the 36 GSM Construction Works Best

CC-1508 may be evaluated for:

• Ultralight down jackets
• Packable padded vests
• Synthetic-insulated garments
• Downproof inner linings
• Sleeping bags and travel quilts
• Insulated hoods and pocket bags
• Lightweight padded accessories
• Compact storage pouches

Its 148 cm finished width provides a practical starting point for garment and sleeping-bag cutting plans. Usable width, edge condition and weight tolerance should be confirmed before calculating bulk consumption.

Because the material uses fine 20D yarns, garment construction requires care. Needle diameter, thread selection, stitch density and seam allowance can affect puckering, needle holes and filling migration. Reinforcement may also be required in areas exposed to repeated friction.

Downproof Performance Depends on the Complete Product

Calendering helps control feather and fibre migration, but the fabric alone cannot guarantee the performance of every padded product. The type and size of the filling, quilting pattern, needle selection and seam construction all influence the final result.

A water-repellent downproof nylon fabric for sleeping bags and jackets should therefore be tested with the actual filling intended for production. Testing an unrelated feather or synthetic fibre may not accurately represent the finished product.

Recommended evaluations include:

• Filling migration through the fabric
• Filling leakage around stitch holes
• Air permeability after calendering
• Tear strength and seam slippage
• Surface marks after folding
• Fabric noise during movement
• Colour fastness and dimensional stability

Water Repellency for Light Surface Moisture

The W/R finish helps occasional moisture bead on the outer surface rather than being absorbed immediately. This can be useful for insulated jackets and sleeping bags exposed to condensation, splashes or brief light rain.

Water repellency should not be confused with waterproofing. CC-1508 does not automatically provide a confirmed hydrostatic-pressure rating, and water can penetrate through quilting holes and unsealed seams.

If measurable waterproof performance is required, an appropriate coating or membrane must be developed separately. Buyers should also specify the required initial water-repellency grade, laundering method and wash-durability target before sampling.

Sampling and Bulk Approval

Before approving 400T downproof nylon fabric, we recommend making a padded test panel or prototype garment using the intended filling. This provides more useful information than assessing the flat fabric alone.

The approval process should cover finished weight, usable width, colour, opacity, surface appearance, hand feel, air permeability and migration resistance. If the fabric will be used as an exposed shell, abrasion and tear requirements should also be confirmed.

Custom colours, hand-feel adjustments and water-repellent targets can be discussed according to the project. Explore additional lightweight materials in our fabric product collection, or follow CC Textile on Facebook for fabric and sampling updates.

Frequently Asked Questions

How is CC-1508 different from CC-1698?
Both fabrics use 20D yarns and weigh 36 GSM, but CC-1508 includes calendered downproof finishing. It is therefore better positioned for down jackets, padded garments and insulated products.

Is downproof performance guaranteed for every type of filling?
No. Calendering helps reduce migration, but results also depend on filling quality, fibre size, needle diameter, stitch density and garment construction. Testing with the intended filling is recommended.

Is CC-1508 waterproof?
No. Its W/R finish helps resist light surface moisture. Waterproof performance requires a suitable coating or membrane and confirmed fabric and garment testing.
