A plied yarn is a thread formed by bonding two or more single yarns. The
strands can also be plied, combined and bonded in a certain way, and the strands
can be re-bonded, such as double-strand, triple-strand and multi-strand. Mainly
used for sewing thread, braided thread or medium-thick and strong fabrics.
Conventional strands are usually made of pure cotton or blended two single
yarns or more than two single yarns bonded together. In recent years, fancy
strands are made of two or more different single yarns bonded together, such as
: Pure cotton and blends, plain and slub yarns, and plain and filament yarns,
etc.
Pure cotton yarn is made of cotton fiber. According to different spinning
processes, it can be divided into carded yarn and combed yarn. Carded yarn is a
yarn spun from cotton fibers through a common spinning system. The combed yarn
is a yarn spun from cotton fibers through a combed spinning system. The combed
yarn is made of raw materials. The fibers in the finished yarn are straight and
parallel, with less knots, good luster, and evenness. This kind of cotton yarn
is mostly used for weaving fabrics. Cotton yarn is widely used, it can be used
as weaving yarn, such as: bed sheets, quilt covers, curtains and other home
textile series. It can also be used as knitting yarn, especially combed yarn can
be used to produce high-quality textiles, such as undershirts, fine-grained
poplin, etc. Cotton yarn can also be used to produce electrical yellow wax
cloth, tire cord fabric, high-speed sewing thread and Embroidery thread, etc.
Pure cotton fabrics are made of cotton as raw materials and produced by textile
technology. They have the characteristics of moisture absorption, heat
resistance, alkali resistance and hygiene. Generally speaking, pure cotton
fabrics have better moisture absorption and heat resistance, and wear. Some work
clothes in industries that require high hygroscopicity of clothing can choose
pure cotton fabrics for processing. For example, summer school uniforms,
etc.
According to the national standard, the yarn quality is rated according to
the quality index and weight unevenness. Cotton yarns are rated according to
evenness, neps, and number of foreign particles. The quality index mainly refers
to the strength of the yarn, which reflects the durability and durability of the
fabric to a certain extent. The grade of the yarn mainly reflects the difference
in the thickness of the yarn and the appearance defects, which directly affects
the appearance of the fabric, such as the evenness of the texture, the size of
the clarity and the shadow, etc. The quality of yarn is closely related to
production management, process conditions, mechanical conditions, technical
operation level, the quality of raw cotton and its rational use. Pure cotton
fabric is a textile made of cotton as raw material, and through the loom, the
warp and weft yarns are interwoven vertically and horizontally. At present,
according to the actual source of processed cotton, it is divided into virgin
cotton fabric and cotton fabric. Cotton with a cotton content of more than60is
pure cotton. Don't39;t think that pure cotton is cotton. They still have different
places.
