Textile Yarns

Lyocell textile lines

The textile common stitching yarns are typically made ​​from spun yarn or in the form of continuous filament yarns , yarns with so called heart .

In the production of sewing thread spun textile yarn , textile cotton fibers were the first to be used, but also the past two decades polyester fibers (PES ) and polyamide (PA) have been frequently applied because , in particular , to their superior toughness compared to the low toughness of the cotton yarn stitching . The disadvantage of synthetic fibers and filaments is that they can not be dyed textile stitching lines in a simple process (with only one phase) with the cotton garments after this be sewn , such as cotton thread.

To overcome the problems caused by the kinds of yarns , described above , there was a need for development of new stitching yarns , one of these cases "a textile seam line that contains the axis of continuous filaments of lyocell lines , covered by cotton fibers "if this wire texteil patented ( patent number 102650 ) by the company VALFIOS - Trade in textiles yarn, although the authors of the patent TEACHER Lubos HES , PHILIP ARTHUR DOS SANTOS FERNANDO HENRIQUES and ENG º PINE NOVAIS.
Note : this line is under study and development , did not allow any kind of supply.

The invention relates to a sewing thread with web of continuous filaments for fabrics and garments which consists of at least 50% of the weight of the portion of the sewing yarns as Lyocell heart (middle), and at least 15% portion of the weight of cellulosic fibers (for example cotton or viscose ) , wrapped around the shaft , thereby completing the outside thereof and this complex textile stitching thread . Due to its superior toughness , dimensional stability and low friction surface , this wire is especially suitable for sewing cotton medium and heavy , such as : denim fabrics , velvet fabrics , flannel fabrics , cotton jackets , protective clothing cotton , etc. . Moreover, such a wire has the advantage of cellulosic dyeing cotton garments sewn crude ( yarn and fabric ) in a single operation.


This new line of sewing textile displays the following advantages:

The new line of stitching is adequate to meet the current requirements of the market, ie, the exact time ( JIT ) for product delivery . Because lyocell, cotton and rayon fibers are of cellulose can be dyed only to a wire or with the product already sewn in a single dyeing process (preferably direct mode ) , which results in great savings financial. This will reduce the stock of textile yarn , originally dyed in 300 colors and shades of sewing thread textile for frameworks , which will reflect major economic effects . The possibility minor proportions of filaments of continuous synthetic yarns of different dye affinities should not cause problems in color and tone of the final seam line.

Tenacity , elasticity and dimensional stability which is equal or better than the characteristic parameters of the stitching thread shaft PES / CO.

A sewing thread made ​​of environmentally friendly natural renewable resources, which will automatically decompose when discarded. The wire can also be burned wasted without generating toxic gases.

A line of stitching textiles, highly resistant to high temperatures caused by friction generated during the sewing process , able to follow technological developments of modern sewing machines unlike the ordinary sewing thread soulful PES / CO.

A sewing thread whose coating cellulosic textiles (cotton or viscose) exhibits excellent adhesion to the surface of Lyocell due to the high friction surface typical of a single filament lyocell.

1 - Cotton yarn textiles
An important aspect is the knowledge of the linear density of the yarn, because it allows for the same category of wire, choose what best suits the conditions of use of the article.

Indeed, the linear density of the yarns influence:

· The strength of the yarn and consequently the resistance of the seam;

· The choice of the number of needle;

· Filling cinnamon;

· The pitch of the sewing machine tensioners;

· The risk of curl lines.

The linear density can be expressed in several ways:

Tex
Ne
nm
denier

Tex and Ne are the most used in sewing
 

2 - Wire Twist textiles
The number of turns of wire stitching around its axis, determined based on their nominal gauge length before the distortion.

The twist should be expressed preferentially in turns per meter (turns / m) can also be expressed in turns per cm (turns / cm) and (turns / inch).

The steering torque is very important. The twist may be in the clockwise direction, Z- twist , known as left twist, or in the opposite direction to the clockwise twist forming S, known as right twist.

The Z- twist is more appropriate for larger paret sewing machines because with the twist S distorts the sewing thread during sewing thus causing distortion and breakage of the line.

 

3- Coefficient of friction of textile yarns and stitching footwear
It is sliding against the force of a wire in contact with a cylindrical body where there are opposing forces. One cause of needing to change the needle often is the great wear caused by friction of the yarn on the metal.

The heating of the needle and breaks frequently abnormal, are also consequences of friction. The friction properties of a wire depend on the characteristics, but above all the finishing products and lubricants. Lubrication of a wire is very important, because it reduces friction and protects the wire against heat. It is in these cases necessary to make a test of friction or slip on a metal wire, which permits to detect whether the wire will wear material, or affect the characteristics and service life of the organs of the machine.

A high lubricity can cause staining on parts, creating a huge problem because the removal is very expensive and in some cases impossible.
 

4 - Error
The irregularity of the yarn, ie the variation in mass per unit length is considered to be an important and critical, as it may cause breakage of the seam line. Irregularities can be found at any stage of the textile process, ie, appear on wires, fuses, blankets and ribbons.

The length and diameter of the fiber are important properties for determining the behavior of these in the spinning process. There is a high correlation between the irregularity of the yarn and the average length of the fiber.

The variations in the cross section of the wire, as neps , thin places and thick places, are usually described as imperfections and are analyzed in parallel to the irregularity.

It is important to realize that all the wires are somewhat irregular, and its value is the determining factor for the acceptability or otherwise of the product by the consumer.

 

5 - Rupture resistance of fiuos sewing textiles and footwear
Maximum force applied in a tensile test carried to rupture. To yarn is preferably expressed in centinewtons ( cN 1GF = 0.98 ) can also be expressed in kilograms or grams (force).

This varies slightly according to the specific conditions under which the wire was broken, for example, humidity, temperature, charging rate and length of the wire subjected to tension. For this reason, all of these conditions are specified accurately in all internationally recognized tests. These tests are conducted in standardized laboratory environment with automated instruments and usually using electronic load cells.

 

6 - Tenacity fuos sewing textiles and footwear
Ratio of tensile strength of the wire , relative to their linear density . It is usually expressed in centinewtons per tex ( cN / tex).

Of course, to produce the thicker a wire , the more resistant it will be. But the tenacity is theoretically independent of the linear density of the yarn and can therefore be used to compare the resistance of fibers and wires. The tenacity can be expressed in various ways grams (force ) per denier (g / d ), and grams ( force ) tex .

 

7 - Elongation at break yarn sewing textiles and footwear
Increase in length of a specimen produced by the breaking force. It is expressed as a percentage of the original nominal length.

This is important , being one of the factors involving the enhancement of the elasticity of the seams. By itself is important because it identifies the behavior of the yarn stitching.

 

8 - Elasticity sewing thread textile and footwear
It is the property of a thread by which it tends to recover its original length after being stretched to a certain point. For example, the gum regains its original length, is therefore highly elastic , with a 100% elastic recovery.

A polymer unstretched, is said to have high plasticity with elastic recovery zero.

PROPERTIES OF COLOR

The color is a very complex function of many variables and . White light is a combination of many individual colors or wavelengths of electromagnetic radiation. The distribution of intensity of these wavelengths is known as the spectrum varies significantly and the sun , light bulbs and other light sources much .
Any one color visually examined depends on the individual color vision or the environment in which the color is observed.

Visual color comparison :
There are many aspects that should be avoided when comparing samples visually , as described by the following aspects .


1 - Dichroism

It is an apparent change color when changing the direction of the vision . Has a tendency to occur in the tissues over the wires, but it can affect the approval or not the color of a yarn.


2 - Metamerism

It is a color change that occurs when changing lighting conditions .
For example , if we observe an object the light green day , a certain amount of light is reflected as green. If we observe the same object under a fluorescent light that is rich in red and blue, but deficient in wavelength green and yellow , so there is less light available to reflect , so this object will appear to have a different color and show a lack of continuity color .

To compare the color that is a serious problem, because the two samples compared to light , it is possible that these two samples do not alter the color gradually under artificial light. This is due to the fact that certain mixtures of dyes have different absorption characteristics , this is the so-called " illuminant metamerism ."
When two independent observers do not have a color in the same way is called " metamerism of the beholder ."
When a color looks different according to the viewing angle is called the geometric metamerism .
When Valfios reproduced in one color, the dye mixture is carefully examined in order to reduce metamerism .


3 - Conditions of visual analysis

A sample of different color backgrounds examined on the color analysis by the observer can be influenced and to see color differences in the sample, this effect is called simultaneous contrast .

The color visual comparison to be made at standard conditions , ie under a standard illuminant compared cabin and a standard visual analysis ( light box ) .


4 - Changes over the standard

The characteristics of the surface of a wire can have an influence on visual comparison and can produce disagreements about the acceptance or rejection by analysts , for example, when comparing the color of the continuous filament ( that has much brightness ) of the color of the spun yarn ( which has fibrous surfaces mates ) .
Either way , it is not always stable selection of colors by the human eye ( the age and sex of the observer aspects are variables). For requirements comparator critics shades selected can be analyzed when sewn into the fabric .

The passage of the wire through the sewing machine can affect its color to change the character of the surface and balance of twist.
The stitching in areas of the piece with different densities can cause differences in shade . The lubricant may also affect the hue .


5 - Measurement of Color

All colors sold in Valfios be adopted by a color reading in the spectrophotometer , comparing with a standard sample .
The spectrophotometer measures and modern automatically records the color spectrum of a sample compared with the standard .

Besides this reading all colors are visually compared in a light box , all this work is done to ensure continuity of color from which to start.


6 - washing fastness and color change

After selecting a line color of the stitching suitable material to be used as sewing or contrast , it is important that the color of the thread to remain solid throughout the useful life of the material.

For this reason tests are made wash fastness and color change to the line at all matches dyed .
You should then check the robustness of dyed ( color changes , staining ) of the seam line .
One can imagine the catastrophe that is when a garment stain, because of an embroidery and / or have stitched a fabric with a clear dark thread , poor strength .

Similarly , a line of stitching must remain in the same tint of the fabric after washing or dry cleaning .
