Nanotechnology Benefits in Fabric Formation

Nanometer (Nm) resins have been shown to modify fiber behavior in existing textile yarn. Incorporation of nanometer (Nm) resins in conventional warp size formulations improve weaving performance, improve fabric quality and reduce cost.

Basic Weaving Operations

In weaving, no matter what type of weaving is being done, four major operations are performed in sequence and are continuously repeated, they are Shedding, Picking, Beating Up, Taking Up and Letting Off.

Skip and Pointed Twills

Skip twills are a type of broken twill effects formed by a skip drawing-in draft and a regular twill weave as a chain draft. The weaves that form a wave effects across the cloth known as pointed twills. These effects are also frequently spoken of as herring banes, or herring-bones stripes, because the radiating twill lines suggest the radiating bones of a fish’s backbone.

Fancy entwining and Curved Twill

Fancy entwining twill effects are obtained by omitting one or more twill lines from each section and continuing the remaining twill lines of each section until they meet these of the other section. By this it means that two blank spaces are made in the weave, in which other weaves may be inserted. Curved twills are those in which the twill lines have a wavy, or curved, nature instead of being perfectly straight as in an ordinary twill weave. There are two methods of constructing these weaves,

Fancy Twills

The fancy twill is formed by placing small spots between the main lines of twill. The first end of the weave should be a continuation of the last end and the first pick should be a continuation of the last pick, so that the weave will continue perfectly when repeated in either direction.

Derivatives of twill Weaves

Derivatives Formed by Rearranging Ends or Picks- The number of what may be termed fundamental weaves is comparatively small, but the weaves that may be derived from them are innumerable. Thus, if a simple twill weave is shown out in design paper, several other weaves may be obtained from it by rearranging either the ends or the picks. Designs thus obtained are termed derivatives.
