Simplex & Double Needlebar Knit Fabric

Fairlane provides simplex & double needlebar knit fabrics that are characterized by excellent stretch and recovery without the use of touchy elastomeric yarns and fibers. Simplex fabrics are double needlebar fabrics which usually have the same appearance (and characteristics) on the front and the back. They possess excellent drape, luxurious appearance, hand and strength.

Most versions of simplex & double needlebar knit fabrics are moldable into shape through the application of heat. End uses for simplex fabric include athletic wear, intimate apparel (brassieres), gloves, digital printing, projection screening, home furnishings and filtration. Fairlane offers simplex fabric in the following types:
  • Jersey
  • Eyelet
  • Mesh
  • Pocketed Tubular
  • Pattern Fabric
  • Engineered Pattern Bands

Simplex Knit Fabric Capabilities

Jersey Simplex

This workhorse construction has the classic width and length stretch without the use of elastomeric (spandex) fiber. Spandex can be an issue in industrial applications or in applications where longevity is important. Spandex can sometimes also have too much give. These simplex fabrics can stretch and recover without the wah wah stretch of spandex. If you examine the face and the back of the simplex jersey, you will see virtually no difference. This can be important not only in appearance but in performance and feel.

Eyelet Simplex

The same good characteristics of jersey can be embellished with the addition of an eyelet pattern. Surface interest for apparel end uses such as intimate apparel or athletic-wear is provided.

Mesh Simplex

The same on the front and back, possessing an excellent hand and drape and a modern ultilitarian look.

Pocketed Tubular

The simplex fabric can be engineered to provide a series of lengthwise pocketed openings according to the customer needs and specifications.

Pattern Fabrics

For apparel, applying an interesting pattern to a workhorse ground fabric can spark the attention of the customer. Many patterns are available to fill this need.

Engineered Pattern Bands

A lengthwise pattern which repeats across the width can be engineered into a simplex fabric. What you get is a pattern of varied appearance alternating with a solid fabric. The repeats and widths of the patterns are according to the customer needs.

    Fabric Engineering Guide

    Fiber Content

    Nylon, Polyester, Cotton, Rayon, PLA, Acetate, Carbon, Nomex

    Yarn Type

    Filament Yarns: Filament yarns are yarns produced through the extrusion process. The filament is continuous from beginning to end. There is no 'hairiness' to the product made from filament yarns unless it is intentionally applied post finishing.

    Spun Yarns: Spun yarns are produced from short pieces of yarn and spun into a single strand. Upon examination the spun yard reveals the ends of the short pieces sticking up.

    Yarn Size

    Yarn size is the single largest determining factor in weight and opacity of fabric. Our fabrics run in the range of 15 denier to 150 denier.

    Yarn Luster

    Yarn may be bright, dull or semi dull, usually dependent on the customer's aesthetic requirements.

    Filament Count

    Filament count effects the hand of the finished fabric; the higher the count, the softer the hand. Filament count also effects the appearance of the finished fabric with lower filament counts effecting a leaner appearance.

    Yarn Color

    Yarns can be dyed by the manufacturer prior to fabric formation thereby achieving high colorfastness and color consistency from lot to lot.

    Specialty Yarn Properties

    Flame Retardency, Moisture Management, Recycled, Stretch, Anti Microbial, Anti Static

    Fabric Width

    Warp knit fabrics of our manufacture have the distinct advantage of being delivered to the customer in widths from as low as 1/4" to 220". In order to achieve widths of less than 36", our fabrics generally require a post production slitting process.

    Fabric Weight

    Fabric weight is the single largest determining factor in performance and cost. Fabric weights produced on our equipment can range from .45 ounces per square yard to 8.5 ounces per square yard.

    Fabric Coloration

    Fabrics may be dyed after they are manufactured into virtually any color or they may be left in their natural state. Colors can be submitted for matching by the customer on other fabrics, other products or Pantone number. We have a wide variety of colors in our archives from which customers can choose. In some cases, solution dyed yarns can be used instead of fabric finishing to achieve extremely consistent color matching from lot to lot or very high color fastness.


    The fundamental principle of yarns used in manufacturing our product line is that in order to change the permanent shape of our fabrics, heat must be applied in excess of heat previously applied. Low heats during fabric processing will allow low heats used by customers to change the shape of the fabric. Fabrics can be permanently molded into shape by the customer through the application of heat in excess of our processing temperatures. Processing temperatures can be dictated by customer needs.

    Surface Treatment

    Fabrics can be printed for appearance, embossed for texture and appearance, brushed for softness.

    Finish and Hand

    Finishing additives can be used to achieve hands from very soft to very firm for a variety of end uses. Finishes may be water soluble or not.

    Finishing Additives

    Additives can be specified in our finishing processes to achieve: Flame Retardency, Anti Static, Anti Microbial, Wicking/Moisture Management
