Why woven fabrics made of cotton are easy to tear 15

How to ** Stretch strength and tear strength of woven fabrics.

As we all know, export fabrics must have the requirements of tensile strength and tear strength. （astm for and iso for europe ）.After the customer gives a request, it is often not sure whether my product is up to standard, unless you first set up a request in ITS, BV, SGS....Wait for prenatal testing, but in this way, it will definitely increase the cost greatly and be very troublesome. Here, I would like to ask you how to make some predictions for yourself. and learn the main factors that affect tensile strength and tear strength.

Factors influencing tensile strength:

1.The single strength of the yarn. (Combing, combing, etc.).

2.The number of warp and weft density (the higher the density, the better the tensile strength) 3Pre-treatment quality prior to staining. If the control is good, the strength will be reduced. (But I don't know the details and the underlying reasons).

Factors that affect tear strength.

1.The single strength of the yarn. (Combing, combing, etc.).

2.The tightness of the fabric (it seems that the tightness is high, but the strength is poor)3Some special finishing requirementsFor example, anti-crepe finishing will reduce strength....Wait a minute.

Copied, but I know this answer is right, hehe, what other specific questions can you ask me.

The reason is simple.

1 Cotton yarn has a lower strength than other yarns.

2. The texture of the fabric, the general cotton is plain or simple twill.

3 The yarn density of cotton cloth is generally low.

Woven cotton is a cotton fabric. The weaving in this noun refers to a weaving method, in which the thread is made into cloth by throwing a shuttle, while the woven cotton is made from cotton thread.

In today's society, with the continuous development of various industries, all kinds of things emerge one after another, and even fabrics have developed many styles. From the perspective of our daily life, there are common polyester, silk, cotton, etc., according to the different styles and textures of the clothes will choose different fabrics, and some people will also analyze the advantages and disadvantages of these fabrics according to their own dressing habits. However, the whole market still has a preference for cotton fabrics.

Woven cotton is a kind of cloth that is more popular and common among the public.

Woven fabric is a loom in the form of a shuttle, the yarn is composed of the yarn through the interlacing of warp and weft, and its organization generally has three categories of plain, twill and satin and their variations. This kind of fabric is strong, crisp, not easy to deform because of the warp and weft interlacing of weaving, and is classified from the composition of cotton fabrics, silk fabrics, wool fabrics, linen fabrics, chemical fiber fabrics and their blended and interwoven fabrics, etc., the use of woven fabrics in clothing is in the leading position in the world in terms of variety and production quantity. Widely used in a variety of high-end rolling clothing, woven clothing because of its style, technology, style and other factors in the processing process and means of great difference.

Woven cotton can contain other ingredients, pure woven cotton is what we call pure cotton fabric, woven refers to the use of a shuttle loom to weave. Generally, the fabrics are woven with a shuttle loom, as for whether the ruler is comfortable, it depends on the cotton content and grade, and the washing label of the general ** clothes are clearly marked.

If not dealt with in time, the cotton yarn may appear moldy, falling off and other phenomena, these problems can be alleviated by timely cleaning and repair, but when there is a large area of moisture, it can only be re-woven after shoveling the cotton yarn.

Woven fabrics will pill.

The main reason for the pilling of the fabric is the fiber length of the yarn and the tightness of the fabric. Yarns with static electricity, such as TR, are relatively more pilling. Fabrics with loose fabric are also prone to pilling.

Woven fabric is a loom in the form of a shuttle, the yarn through the warp and weft staggered and composition, its organization generally has plain, twill and satin three categories and their variations. This kind of fabric is strong, crisp, and not easy to deform because of the interlacing of warp and weft weaving, and is classified from the composition of cotton fabrics, silk fabrics, wool fabrics, hemp fabrics, chemical fiber fabrics and their blended and interwoven fabrics.

Mainly depending on the material, acrylic material is particularly easy to pill, but acrylic imitation wool yarn is generally used more knitted fabrics, so you will have such an illusion, it is not that woven fabrics will not pill, not very good woven woolen fabrics, acrylic content is high, or has not undergone anti-pilling treatment, it is also easy to fluff.

Woven fabrics don't pill and pilling.

The main reason for the pilling of the fabric is the fiber length of the yarn and the tightness of the fabric.

Yarns with static electricity, such as TR, are relatively more pilling.

Fabrics with loose fabric are also prone to pilling.
