HUCK A BACK WEAVE, A WOVEN FABRIC WEAVE
HUCK A BACK WEAVE, A WOVEN FABRIC WEAVE:
The Huck a back weave has long yarn float and firmness both. This weave shows good moisture absorbency. This weave is widely used for bath towels and kitchen linens. This weave has combination of plan weave and long floats. The whole construction is divided in four equal parts. You can also say that this weave has four quadrants. Two quadrants have plain weave and other two quadrants has systematically arranged long yarn floats. The plain weave imparts firmness to the structure and long yarn floats helps to increase moisture absorbency. Some examples of Huck a back weaves are given below:

TESTING OF YARN COUNT FROM FABRIC SWATCH BY BEESLEY BALANCE
TESTING OF YARN COUNT FROM FABRIC SWATCH BY BEESLEY BALANCE:
Beesley balance helps to find the yarn count from the fabric swatch quickly. The Beesley balance doesn't need electric power. It is very simple instrument which can be installed at any place. Portable Beesley balance has also been developed which can be carried any place. A template is also supplied with the instrument which helps to draw cut mark on the fabric swatch. There is no need of measuring scale. The whole testing procedure of count determination is given below:

Portable Beesley balance has also been developed which can be carried any place. A template is also supplied with the instrument which helps to draw cut mark on the fabric swatch. There is no need of measuring scale. The whole testing procedure of count determination is given below:
Apparatus used:
1 - Beesley balance.
2 - Marking pen.
3 - fabric swatch .
4 - scissor.
Description of template:
As you can see in the picture, it is a flat PVC. plate. It has six sides. The length of the each side of this template is fixed according to fibre used in the yarn. You can determine the count of yarn made of linen, cotton, worsted, wool.
Specimen preparation:
It is very simple to prepare the specimen. Here one thing should be kept in your mind that specimen should be slightly bigger than the side of the template. Suppose that you are going to find out the count of cotton yarn, then the length and width of the specimen should be slightly bigger than the length of the cotton side of the template.
The fabric swatch is spread over the flat surface. The cutting template is placed on the fabric swatch. The marking of the cutting marks is done both sides. Now the template is lifted from the fabric surface.
A half to one inch deep cut is made along the marking lines on the both sides. The yarn of the fabric made aligned.
Preparation of Beesley balance for test:
The Beesley balance is placed over the flat surface. The leveling of the balance is done with the help of leveling screw. Now the zeero pointer position is found by leveling the instrument.
After setting zeero pointer position, the rider ( a hook of steel wire having specific weight) is place in a slot on the lever of the balance. As we place the rider, the pointer side of balance lever gets down. The other side of the balance lever has a hook . The threads are hanged on this hook. You can see in below figure:
Now our Beesley balance is ready for testing.
Testing procedure:
The threads from the prepared specimen is taken out one by one. The threads are hanged on the thread hanging hook. These threads are hanged one by one on the hook. When the number of threads gets increased gradually, the balance lever starts to lift from the pointer side. A position comes at a time when the balance lever and point get levelled to each other. As the balance lever gets levelled with pointer, we stop to hang the threads in the hook.
"Now the hanged thread are taken off. Now the threads are counted. The total number of threads are equal to the yarn count".
