Grasp Some Simple Identification Methods Of Fabrics.

< p > > a href= "http://www.91se91.com/" > cotton fabric < /a > soft and comfortable handle, good hygroscopicity and permeability. Therefore, cotton is generally used to make < a href= "http://xm.sjfzxm.com/" > underwear > /a > a href= "/a" > pajamas < > and baby garments.

But its elasticity is poor. The fabric is easy to wrinkle and gloss after hand holding, so its fabric is poor in shape, and the clothes made in general are mostly sportswear and casual wear.

When the fibers are burning, they are close to the flame without shrinking or melting, and the contact flame burns rapidly. After leaving the flame, it can continue to burn. It has the smell of burning paper, the ash is a little gray, and its ashes are lighter.

The appearance and combustion state of artificial cotton is close to that of cotton, but the fabric will harden after launching, and the strength will be greatly reduced, and the strength will drop by nearly half.

You can try one or two yarns.

< div > > a href= "http://www.91se91.com/" > hemp fiber > /a > hand feeling is relatively coarse and hard, and often because of its surface colloid and integrated bundles, fiber length difference is large, short fiber content is more, its characteristics are basically similar to cotton fiber, but its hygroscopicity and permeability are good, and easy to wash and fast drying, so it is the ideal material for summer shirts, because linen fabric is more smooth, smooth and elastic, and fabrics are not easy to wrinkle.

So it is often used to make a good coat.

< div > < a href= "http://www.91se91.com/" > wool fiber > /a > hemp and cotton fiber should be long, its fibers are curly soft and elastic, and it is not easy to wrinkle.

Its fibers have a unique property: velvet, so the woolen garments are easy to shrink and the thickness will increase. Therefore, a lot of woolen products will be processed at first when finished products, so as to prevent the deformation of the finished products.

When the wool fiber burns near the flame, it does not melt. It burns near the flame, burns away from the flame, and sometimes burns itself out. It has the smell of burning hair and nails.

When the block fabric is burned, bubbles can be seen on the surface of the fabric, and the ashes are loose, crisp, black irregular blocks or small balls.

Ashes are crushed by hand.

The artificial wool shrinks close to the flame, and it burns rapidly near the flame, and when it burns, there is black smoke coming out. Its smell is pungent and pungent, and the ashes generated are hard black globule.

It is close to the burning state of plastics.

< div > the length of silk fiber is much longer than that of hemp and cotton fiber and has a special luster.

The fiber burning state is close to wool.

When the fabric is close to the skin, it is smooth and comfortable, and its air permeability is also good, and has a certain luster, so it is often used to make high-end shirts, pajamas, dresses, etc.

The fibers are strong enough to be heard by hand rubbing.

Its surface is less hairy.

Rayon feels rough and hard and feels cold and damp.

Silk is glossy but not dazzling, while rayon rayon has unique metallic and natural luster.

When the fabric is tightly held for relaxation, the artificial silk fabric has more wrinkles and fewer silk wrinkles.

With the tongue lick and wet it, the silk fabric will break easily and the silk will be stronger.

< div > above is a simple and easy identification method of < a href= "http://www.91se91.com/" > pure fabric > /a >.

For a href= "http://www.91se91.com/" > interwoven fabric < /a >, the warp and weft yarns are mostly interwoven with different fibers, so as to achieve the goal of complementarity.

Therefore, the warp and weft yarns can be extracted separately when they are identified, and the warp and weft yarns are separated separately for combustion identification.

To determine its constituent elements.

< a href= "http://www.91se91.com/" > blended fabric < /a > is made of different fibers blended in a certain proportion. It is relatively difficult to identify. It can be roughly judged on the composition of warp and weft yarn by means of the identification method of interwoven fabric.

With the progress of society and the continuous improvement of science and technology, fabrics are constantly upgrading.

The above is the identification method of common fabrics. Now there are a wide variety of fabrics, specially treated < a href= "http://www.91se91.com/" > fabric < /a >, new fabrics emerge in an endless stream, and their identification methods must be constantly updated. Therefore, the above a href= http://www.91se91.com/ "identification" /a "method is only for reference.
