Norville Industries carries a wide variety of threads. With over 50 years of experience in the textile arena, we have put together a team of manufacturers to service all of your thread needs. Some of the various threads we carry are polyesters, nylons, cottons, polypropylenes, and other specialty threads. There are also combinations of the various fibers available as blends.

Threads can come in many different put-up sizes. Some of these include: bobbins, 8 ounce cones, 1 pound king spools, 2, 3 and 5 pound spools. Thread stands are also available that can accept cones as small as 8 ounces and will also adapt up to fit a 5 pound spool.

Polyester: This thread is mainly used for butt seaming rolls together or where chemicals are used. It has a high tensile strength of 20 lbs. The fluorescent yellow, orange and metallic are used in conjunction with sensoring equipment.

12/5, 100% polyester, white, fluorescent yellow, orange and metallic in 8 oz., 1 lb., 1.5 lb. and 5 lb. put ups 8/6, 100% polyester, white, and white and colors in a barber pole construction

Textured Polyester: This thread is mainly used for serging because of its affordability. It has a soft hand and good bulk when relaxed so it takes fewer stitches to cover the same area as other thread types.

T-70, 2/300, 100% poly, white or colors

Spun Polyester: A good thread for binding and surging, where color matching is an issue.

20/3 T-80 spun poly, various colors including barktan
30/3, T-60 spun poly, white, mothergoose and various colors
30/2, T-40 spun poly, white, black, barktan and various colors

Polyester/Cotton: 12/5 Poly/Cotton, white, various put ups from 1 lb spool to a 20 lb cone

Polypropylene: This thread, being recyclable and less expensive, is often used for bag closing.

Bonded Nylon: Bonding means the thread has been treated with a liquid resin that is cured and lubed. This process prevents fraying of a cut end and also protects against heat damage caused by high speed sewing. It can be used for serging rugs as the lockstitch, sewing leather goods, automotive trim, and anything that requires good abrasion resistance. The bonded nylons can be made in various sizes and colors. The finer the thread, the lower the number will be. For example, a size 69 thread will be a smaller denier than a size 138.

Tex 70, ~11.0# tensile strength
Tex 135, ~22.0# tensile strength
Tex 210, ~32.0# tensile strength

Nylon Monofilament: This thread is translucent and blends in well with colors. It can also be made in a smoke or various other colors. It is used in sewing bedspreads, hats, pillows, stuffed toys, carpet & rugs, tents, awnings, boat covers, flags & banners, indoor & outdoor furniture, curtains, drapes and apparel. A UV thread is also available in the monofilament ranging from a 6 mil to a 14 mil. We also carry the canister tops to fit the spools.

7 mil, 3.6# tensile strength
9 mil, 6.0# tensile strength
10 mil, 7.4# tensile strength
11 mil, 7.6# tensile strength
12 mil, 9.8# tensile strength

Twisted Nylon: 600 Ply Twisted Nylon, White

Specialty Thread: These threads can be used for fire suits, ballistic clothing, wiring applications and other sewing applications where heat resistance is a must.

Kevlar - By weight is stronger than steel  Nomex - Heat resistant characteristics

The tensile strength of a thread is determined by many factors, the type of fiber (cotton, polyester, nylon), the number of plys in a thread and the strength of each individual ply.


Denier to Tex: Tex = Denier : 9

Tex to Denier: Denier = Tex x 9

Cotton Count = 5315 / Denier

Yards/Pound = Cotton Count x 840

Yards/Pound = 4464492 / Denier


Butt Seaming Thread: A Thread intended for seaming two material edges butted against each other.

Denier: The mass in grams of 9000 meters of a fiber, filament or thread.

Sewing Thread: A thread intended for stitching material either by hand or by machine.

Spun Thread: Commonly used to describe a thread that consists of staple fibers held together usually by twist.

Textured Thread: A continuous-filament thread that has been processed to introduce durable crimps, coils, loops or other distortion along the length of the filaments.

Twist: The condition of a thread when the component elements have a helical disposition such as results, for instance, from relative rotation of the yarn ends. For all practical purposes twist is measured in turns per unit length.

Twist Direction: Twist is described as S or Z according to which of these letters has its centre inclined the same direction as the surface elements of a given twisted thread, when the thread is viewed vertically.
