Flannel is a soft, brushed woven fabric with a fine fuzzy surface that delivers exceptional warmth, breathability, and comfort across a wide range of seasonal garment applications. Unlike many fabrics where hand feel is a secondary specification, flannel's defining characteristic is its surface texture — produced by brushing the woven base fabric to raise fine fibers from the yarn structure, creating the characteristic soft nap that makes flannel the preferred fabric for pajamas, children's clothing, casual winter wear, and thermal uniforms worldwide. XINGYE TEXTILE supplies wholesale flannel fabric in 100% cotton, polyester-cotton (TC), and 100% polyester compositions — factory direct from our production facility in Shijiazhuang, China — covering the full range of cost, softness, and durability requirements for garment manufacturers and wholesale buyers.

What Is Flannel Fabric?
Flannel is defined by its production process as much as its fiber content. The base fabric — woven in plain or twill construction — is subjected to a brushing or napping process after weaving, where fine wire rollers raise the surface fibers from the yarn to create the characteristic fuzzy, soft nap. This brushed surface is what distinguishes flannel from standard woven fabric at the same fiber composition and GSM.
The brushing process produces four performance properties that drive flannel's dominance in cold-weather and comfort apparel:
Exceptional softness. The raised fiber surface creates a fabric that feels significantly softer against skin than unbrushed woven fabric at the same fiber content. This is the primary reason flannel is the default fabric for pajamas, sleepwear, and children's clothing where skin contact comfort is the key specification.
Thermal insulation. The raised nap traps air within the fiber structure, creating an insulating layer that retains body heat more effectively than equivalent smooth-surface fabrics. This thermal performance makes flannel the standard choice for winter uniforms, cold-weather workwear, and layering garments in low-temperature environments.
Wrinkle resistance. The napped surface structure absorbs and distributes stress more evenly than smooth woven fabric, giving flannel better wrinkle recovery than equivalent plain or twill weave at the same weight. Flannel garments maintain a presentable appearance through extended wear without pressing.
Breathability. Despite its warmth, flannel's open nap structure allows moisture vapor to escape, preventing the clammy feeling associated with non-breathable synthetic insulation. Cotton and TC flannel in particular maintain good breathability alongside their thermal properties.
Flannel Fabric Compositions — Which to Specify
XINGYE TEXTILE supplies flannel fabric in three base compositions, each suited to different performance requirements, price points, and end-market positioning.
100% Cotton Flannel Pure cotton flannel delivers the softest hand feel and best breathability of the three composition options. Cotton fiber's natural moisture absorption and breathability make 100% cotton flannel the premium specification for pajamas, infant and children's clothing, and direct-skin-contact garments where natural fiber comfort is the primary requirement. Cotton flannel is also the appropriate specification for buyers requiring GOTS organic certification or natural fiber positioning in their product communications.
Trade-offs: higher cost per meter than TC or polyester flannel, lower dimensional stability without Sanforized pre-treatment, and reduced abrasion resistance compared to synthetic blends.
Best for: premium pajamas, infant sleepwear, children's clothing, organic-certified garment programs, natural fiber retail positioning.
TC Flannel (Polyester-Cotton Blend) TC flannel blends polyester and cotton — typically in 65/35 or 80/20 polyester-to-cotton ratios — to combine the softness and breathability of cotton with the dimensional stability, wrinkle resistance, and wash durability of polyester. The brushed surface retains the soft flannel hand feel while the polyester component significantly improves the fabric's performance in high-wash-frequency applications.
TC flannel is the most widely specified composition for commercial and institutional applications — school pajama programs, hospitality robes, children's uniform garments, and casual winterwear where easy-care performance alongside comfort is the buyer requirement.
Best for: school uniform programs, hospitality robes and sleepwear, children's casualwear, commercial pajama production, mid-price retail casualwear.
100% Polyester Flannel Polyester flannel offers the lowest cost per meter of the three options alongside excellent color retention, dimensional stability, and wash durability. The brushed polyester surface produces a soft nap that closely approximates cotton flannel in hand feel — particularly in fine-denier polyester constructions — while delivering the easy-care performance and color fastness advantages of synthetic fiber.
Polyester flannel is the appropriate specification for budget-tier garment programs, promotional casualwear, and applications where cost efficiency is the primary driver and natural fiber credentials are not a requirement.
Best for: budget-tier casualwear, promotional garments, cost-sensitive pajama programs, winter uniform lining applications.
Flannel Fabric Applications
Pajamas and Sleepwear Flannel's primary application globally. The soft nap, thermal comfort, and breathability of flannel make it the default fabric for adult and children's pajama sets, nightgowns, and sleepwear across all price points. 100% cotton flannel at 150–200 GSM is the standard specification for premium pajama production; TC flannel at 160–200 GSM for mid-market programs; polyester flannel for budget-tier production.
Children's Clothing Flannel's exceptional softness makes it a preferred fabric for children's casualwear, loungewear, and lightweight outerwear. The brushed surface is gentle against sensitive skin, and the thermal properties provide comfort in cold indoor and outdoor environments. OEKO-TEX Standard 100 certification is typically required for children's garment fabric in European and North American markets — confirm certification scope with your supplier before ordering.
Casual Dailywear Flannel shirts, casual trousers, and loungewear are major application categories for mid-weight flannel fabric. TC and polyester flannel at 180–240 GSM are the standard specifications for casual shirt production; heavier weights for casual outerwear and thick casualwear targeting cold-weather markets.
Winter Uniforms and Workwear Heavyweight flannel fabric at 220–280 GSM provides the thermal insulation required for winter uniform programs — security uniforms, outdoor hospitality staff, cold storage facility workwear, and winter construction garments. TC flannel is preferred for workwear applications where wash durability alongside thermal performance is required.
Lining Applications Mid-weight flannel at 120–160 GSM is used as a warm lining in outerwear jackets, coats, and winter accessories. The soft nap provides comfort against the inner garment layer while the thermal properties add insulation without significant bulk.

Frequently Asked Questions — Wholesale Flannel Fabric
What is the difference between flannel and fleece? Flannel and fleece are both soft, warm fabrics but are produced through completely different processes. Flannel is a woven fabric — plain or twill construction — that is brushed after weaving to raise the surface nap. Fleece is a knit fabric — typically 100% polyester — with a deep, plush pile surface produced through a different finishing process. Flannel has a more structured, tailored drape suitable for pajamas and casualwear; fleece has a bulkier, more insulating character used in outerwear and activewear.
Is flannel suitable for year-round production? Lightweight flannel at 120–160 GSM is suitable for year-round pajama and sleepwear production in temperate climates. Heavier weights (200 GSM and above) are primarily seasonal — autumn and winter production for cold-weather markets. Most flannel fabric buyers place bulk orders 3–4 months ahead of the cold season to account for production and shipping lead time.
Can flannel fabric be produced in custom colors and prints? Yes. We support custom dyeing for flannel fabric in buyer-specified colors, with lab dip approval before bulk production. Printed flannel — yarn-dyed checks, plaids, and surface prints — is available on selected constructions. Contact our team with your color or print requirement for a quotation and sample lead time.
Does flannel fabric shrink? Pure cotton flannel can shrink 3–5% in the first wash without Sanforized pre-treatment. TC and polyester flannel have substantially better dimensional stability — typically ≤3% shrinkage. For children's garments and pajamas where consistent sizing after washing is important, confirm shrinkage specification on the fabric test report before bulk production and build shrinkage allowance into pattern grading.
What certifications are available for your flannel fabric? Our flannel fabric is available with OEKO-TEX Standard 100 certification — required by most European and North American buyers for children's garment fabric and skin-contact apparel. Contact our team to confirm certification availability for your specific composition and GSM requirement.
