Texturing of Polyester

Texturising is a process to develop the warmth properties of synthetic by increasing the bulkiness of yarn. A basic discussion on texturing can be viewed here.

To know more about the business of a texturising unit, one can view the draft prospectus of a company which was filed to the Security and Exchange Board of India here.

Spirality and Skew in Single Jersey- Causes and Remedies

This question is posted in a discussion by one of the readers:

I need a solution to control the skew and spirality of single jersey 160g with 30/s. Please provide me with some solution 

Spirality is a dimensional distortion in circular knitted fabric. Spirality is bad as it leads to displacement of seams and mismatched patterns. It can also leads to sewing difficulties. The major cause of spirality is the twist in roving and yarn. To minimize spirality, Z-twist yarns should be knotted on clockwise rotating machine and S-twist yarns on counter clockwise rotating machines. Tighter Fabics exhibit less spirality compared to looser fabrics which means that finer gauge machines will reduce spirality.

It can also be reduced by setting the twist either by autoclave treatment, yarn dyeing or using balanced plied yarns.

Kasuti Embroidery

Kasuti Embroidery

It is a traditional embroidery of the state of Karnataka and is done by counting the threads of the warp and weft with the designs traced or implanted as outlines. 

There are essentially four types of kasuti embroidery. They are Neyge Kasuti, Murgi Kasuti, Menthya Kasuti and Gavanthi Kasuti. Gavanti and Murgi comprise a straight and zig zag stitch. The stitch is identical on both sides of the cloth where as Menthe and Negi Stitch are dissimilar on either side of the fabric. The Difference between Menthe and Negi Stitch is that while the Menthe stitch resembles a cross-stitch, the Negi stitch provides a woven style. These stitches are dissimilar on either side of the fabric.

The Basis of Gavanti and Murgi Stitich is Hoblein Stitich. To understand the concept of Hoblein stitch, you can visit this site.
