Due to different production methods, acrylic yarn can be divided into many
types. So first of all, let&39;s take a look at the production method of acrylic
yarn. The raw material of acrylic fiber is the cheap propylene by-product of
petroleum cracking: because the polyacrylonitrile copolymer is heated to above
230C, it only undergoes decomposition and does not melt. Therefore, it cannot be
melt-spun like polyester and nylon fibers. Method of solution spinning. Spinning
can be dry or wet. Very suitable for short fiber spinning, fluffy and soft. The
polyacrylonitrile fiber has higher requirements on the purity of the raw
material bisacene nitrile, and the total content of various impurities should be
lower than 0.005. The two monomers of polymerization are mainly methyl acrylate,
and methyl methacrylate can also be used, the purpose is to change the
spinnability and the feel, softness and elasticity of the fibers; the third
monomer is mainly to improve the dyeability of the fibers, generally containing
Itaconic acid with weak acid dyeing group, sodium propylene sulfonate with
strong acid dyeing group, sodium methacrylic acid sulfonate, sodium
p-methacrylamide benzene sulfonate, - methyl vinyl with basic dyeing group
Pyridine etc. According to the type of acrylic fabric, it can be divided into
acrylic white yarn, acrylic white yarn, acrylic viscose blended white yarn,
acrylic viscose blended white yarn, etc. According to the thickness of the yarn,
there are various yarn count specifications, mainly:8S, 10S, 12S, 16S, 20S,
21S, 30S, 32S, etc.
There are many types of acrylic fabrics, including pure acrylic fabrics,
and acrylic blended and interwoven fabrics. The main varieties are as
follows:
1. The acrylic pure fabric is made of 100% acrylic fiber. For example, the
worsted acrylic women&39;s woolen fabric processed with 100 wool-type acrylic fiber
has the characteristics of loose structure, bright color, soft and elastic feel,
and the texture is neither loose nor rotten. It is suitable for making middle
and low-grade women&39;s clothing. And using 100 acrylic bulked yarn as raw
material, plain or twill weave acrylic bulked coat can be made, which has the
characteristics of hand-feeling, warm and relaxed wool fabric, suitable for
making spring, autumn and winter coats, casual clothes, etc.
2. Acrylic blended fabrics refer to fabrics blended with wool or mid-length
acrylic and viscose or polyester. Including Nitrile/Viscose Gabardine,
Nitrile/Viscose Ladies, Nitrile/Polyester Tweed, etc. Nitrile/viscose gabardine,
also known as oriental wool, is blended with nitrile and viscose each in a
proportion of50. It has a thick and tight body, strong and durable, and a
smooth, soft, wool-like gabardine-like style, but it has poor elasticity and is
easy to use. Wrinkled, suitable for making cheap trousers. The nitrile/viscose
women&39;s woolen is made of 85% acrylic and 15% viscose, and is mostly woven with
crepe. The surface is slightly fluffed, the color is bright, the body is light
and thin, the durability is good, and the resilience is poor. It is suitable for
outerwear. Nitrile/polyester tweed is a blend of nitrile and polyester with 40
and 60 respectively. Because it is mostly processed with plain weave and twill
weave, it has the characteristics of flat appearance, firmness and no ironing.
Its disadvantage is that it has poor performance, so it is mostly used for
Production of mid-range clothing such as outerwear and suits.
