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 surging 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.
