Once the thread is
constructed, the thread may be finished in several different ways to
enhance its suitability for various end uses. The thread finishes used at
A&E and the relationship between construction, fiber type, and
finishing are listed below. |
|
Soft: |
|
| Refers to
thread that receives no further processing to change its general
physical characteristics. It is dyed to the proper shade and
degree of colorfastness, wound on the proper size package, and
lubricated for sewability. |
|
Gassed: |
|
|
Refers to a
finish where cotton thread is passed through a flame at high speed
to reduce its fuzz and have a greater sheen. Gassing is done in a
wrap form prior to mercerizing and dyeing. |
|
Mercerized: |
|
| Refers to a
finish where cotton thread is treated in a caustic solution under
controlled tension. This process causes the fibers to swell,
resulting in greater affinity for dye penetration. Mercerization
increases the luster of cotton threads and at the same time
increases their strength. |
|
Glaced: |
|
|
Refers to a
finish in which 100% cotton and some cotton wrapped core threads
are treated with starches, waxes, and special chemicals under
controlled heat and then brushed or polished to a high luster. The
result is a glossy, hard finish that protects the thread from
abrasion and enhances ply security during the sewing of hard to
penetrate fabrics. |
|
Bonded: |
|
|
Refers
to a finish where multifilament polyester or nylon is treated with
a special resin that encapsulates the filaments forming a tough,
smooth protective coating on the surface of the thread. This
bonding process adds significantly to the thread's ability to
resist abrasion and greatly enhances ply security during sewing. |
