Sueding Machine | Specification of Sueding Machine

Sueder Machine:
Sueding is a mechanical finishing process in which a fabric is abraded on one or both sides to raise or create a fibrous surface. This fibrous surface improves the fabric appearance, gives the fabric a softer, fuller hand, and can mask fabric construction and subdue coloration. These improved aesthetics can increase the value of a fabric in the marketplace.

In the textile industry, the process of sueding is also commonly known as "sanding" or "emerizing". Normally this process is done only for buyer requirement.

A sueder is sometimes referred to a s a sander since the machine consists of one or more rolls covered with sand paper as the abrasive. Fabrics traveling over these rolls develop a very low pile and the materials surface can be made to feel like suede leather. The hand will depend on the fiber composition, the filament count in the yarn and the intensity with which the fabric is worked.

Filament fabrics can be made to feel like a spun fabric and all fabrics will have a softer hand.

Types of Sueder Machine:
There are two types of sueder machine.
  1. Single cylinder sueder machine
  2. Multi cylinder sueder machine
Single Cylinder Sueder Machine:
With a single cylinder sueder, sueding takes place when the fabric passes between the abrasive covered roll and the feed back-up roll. The opening is adjustable to within 1/10,000th of an inch on contemporary machine models. Designing a machine with such accuracy requires close tolerance manufacturing and a method of maintaining this accuracy under operating conditions in a textile mill.

Multi Cylinder Sueder Machine:
To raise a pile on fabric, the multi-roll sueder relies on tension to allow the abrasive to penetrate the fabric surface. The use of several (usually five) abrasive rolls to perform this task reduces the amount of tension by spreading the work over several rolls. Each roll is independently driven, and can be rotated in a clockwise or counterclockwise direction. Adjustable idler rolls between the abrasive rolls control the slack in the fabric between rolls. Entry and exit drive rolls transport the fabric and control tension. The principle of exposing the fabric to more than one abrasive action area permits the use of a finer grain abrasive.

Good article, I would like to add my experience as developer for finishing tools. The most effective sueding method is to use diamond emery, followed by brushing technology and sand emery.
The sueding method is customer choice depend on fabric structure and production capacities and finish philosophy.
As developer of diamond emerizing tools we can recomment this method because it is the most gentle method to receive a nice even peach effect for a few millions of meters.
Further the process is less agressive, the tear strength of fibre is still very good and the dying performance improove compare to other methods.
This we figure out due to our experience as machine builder for fabric finish in the past and our todays dialogs with our customers.
In case of questions contact me t.ruetten@matchpoint-textile.com
