Why textured yarns are used?
Texturizing processes make yarns more opaque, improve appearance and texture, and increase warmth and absorbency. Textured yarns are synthetic continuous filaments, modified to impart special texture and appearance.
What is a textured filament?
In the broadest sense, any continuous filament yarn which differs from the uniform appearance and smooth texture normally associated with filament yarns might be called a textured yarn.
What are the types of textured yarns?
The following types of textured yarns are distinguished by production method, properties, and use: high-tensile, low-tensile, crimped, loop, shaped, bicomponent, combination, and high-bulk yarns.
What are spun yarn used for?
Spun yarns are long continuous length of interlocked fibers, suitable for use in the production of textiles, sewing, crocheting, knitting, weaving, embroidery, and rope making. Thread is a type of spun yarn intended for sewing by hand or machine. Spun yarns can be made from a number of natural or synthetic fibers.
What is texturing process?
Texturising or texturizing is the process by which synthetic fibres are modified to change their texture – the physical appearance of the fibre. Texturising techniques can include bulking (where thermoplastic fibres are twisted, heat set and untwisted), crimping and coiling, amongst others.
Why filament texturing methods are used?
ﬂat ﬁlament yarns are textured in order to gain increased bulkiness, porosity, softness and elasticity in some situations. Thermoplastic ﬁlament yarns are used in most texturing processes. … The second step is to heat the yarn, which breaks bonds between polymers, allowing the ﬁlaments to stay crimped.
