Description
BACKGROUND OF INVENTION
1. Field of the Invention
[0001] The invention relates to an elastic fabric, in particular to
a unique elastic functional textile fabric made of polyurethane
elastic fiber, featuring highly uniform dyeing, high color
fastness, low chromatic aberration, high flexibility, and high
elastic recovery rate, produced through a special dyeing and
finishing process, and the dyeing and finishing method thereof.
2. Description of Related Art
[0002] The textile industry has developed in Taiwan for more than
50 years. From pure cotton textiles in the early state to the
subsequent chemical fiber textiles, the textile industry has been
one of the key industries in Taiwan. After so many years of
continuous industrial upgrading, Taiwan's textile entrepreneurs
have an in-depth understanding of the newest trend and latest
technology in the textile world. Thanks to persistent effort and
expansion made by relevant manufacturers, the export volume of the
textile industry has always been ranked among the top industries in
Taiwan. In particular, dyeing and finishing is an important sector
to be developed in the textile industry in Taiwan.
[0003] With the economic development and people's increasing
awareness of and care about their own health, the sports industry
is also flourishing, and the sales volume of functional sportswear
is increasing dramatically. Comfortability, convenience and
functional performance of the functional sportswear are often the
key factors for consideration when consumers make purchasing
decisions. In particular, when buying functional sportswear,
consumers care most about elasticity, quick and effective moisture
absorption and perspiration, antibacterial and anti-odor functions,
as well as the light-to-wear property. Among them, the elasticity
of the sportswear can be directly and easily felt and judged by
general consumers with mere sensory touch. As a matter of fact,
elastic textile fabric can reduce the sense of restraint and offer
more flexibility for movement and more comfort in wearing.
Therefore, elasticity is a critical factor to consider when a
consumer makes a purchasing decision. In the current market, common
materials for elastic functional textile fabrics include
polyurethane elastic fibers, polyether ester elastic fibers,
polyolefin elastic fibers, polytrimethylene terephthalate fibers,
two-component composite crimped fibers, hard elastic fibers, etc.
The most successful commercialized elastic fibers in the market are
the polyurethane elastic fibers developed by the American company
DuPont in 1959. In the United States and Canada, it is called
Spandex or Lycra. In Taiwan, it is usually called OP. Because the
polyurethane elastic fiber is composed of special hard and soft
chain interlaced molecular structures, it features high ductility
and high elastic recovery rate. Due to minimal interaction force
between the molecular chains, it can be freely elongated, offering
perfect stretching performance. Its rigid molecular chains offer
strong binding forces and the molecular chains cannot be stretched
indefinitely. Therefore, it offers an excellent fiber recovery
rate. Apart from maximum stretch up to 600% and perfect recovery,
it also features high strength as well as breathable and
wear-resistant properties.
[0004] As mentioned above, polyurethane elastic fibers are playing
a significant role in the textile industry. However, in the
processes of dyeing, false twisting and weaving to make
polyurethane elastic fibers into elastic functional textile
fabrics, there are often such problematic situations as uneven
dyeing, side shading, dyeing creases, poor fastness, poor
elasticity, low elastic recovery rate, cloud spots, unsmooth
surface, or chromatic aberration, or dyelot chromatism. As a
result, when downstream manufacturers and consumers purchase
elastic functional textile fabrics, they are always concerned about
quality difference or poor performance. Therefore, it has become an
important task for textile manufactures to find a solution for mass
production of textile products featuring high elasticity, light
weight, even dyeing, good elasticity, smooth fabric surface and
touch, while at the same time reducing production cost so that
downstream garment manufacturers or consumers will quickly accept
and buy in large quantities. In view of this, fiber textile
processors are currently seeking to develop a production method to
manufacture elastic functional textile fabrics featuring high
elasticity, high dyeing strength, light weight, good heat
insulation, fast drying, comfortable wearing, as well as stain
resistance to make the fabrics easy to wash.
SUMMARY OF THE INVENTION
[0005] In view of the current situation, the inventor has conducted
numerous researches in the development of solutions to the
technical problems mentioned above. Based on years of professional
experience and deliberate survey and study, the inventor has
successfully developed the present invention to improve the
manufacturing processes for elastic textile fabrics, and solve the
problems existing in the prior art.
[0006] The main object of the present invention is to provide
improved production processes to greatly enhance the dyeing
quality, smoothness and elasticity of functional elastic fibers and
to produce elastic functional textile fabrics with optimal
functional performance.
[0007] Another object of the invention is to solve the common
problems of insufficient weft weight, water ripples, unsmooth
surface, pitting surface, creases, uneven dyeing, side shading,
poor fastness, chromatic aberration, dyelot chromatism,
insufficient elastic force, and spray burns through special
improved production processes, and to enhance the quality and
performance of elastic fabrics.
[0008] A further object of the invention is to simplify the
original complicated manufacturing procedures through special
improved production processes. The fabrics are directly washed
after high-temperature dyeing, and then the fabrics undergo a
setting procedure, thus saving a lot of processing time and
considerably reducing the manufacturing cost.
[0009] In order to achieve the above objects, the method disclosed
in the invention comprises a medium and light color dyeing and
finishing method and a dark color dyeing and finishing method,
respectively comprising following steps:
[0010] Medium and Light Color Dyeing and Finishing Method: A fabric
is provided. The fabric comprises at least one elastic yarn. A
ironing machine is used to process the fabric. The fabric undergoes
an ironing procedure at temperatures from room temperature to
110.degree. C., 130.degree. C. and 150.degree. C., to maintain
warp-wise smoothness and flatness. After ironing, a sanforizing
machine is used to sanforize the fabric. Then after loosening, the
fabric undergoes a scutching procedure. Then, a setting machine is
used to preset the scutched fabric at temperatures from 180.degree.
C. to 195.degree. C. Then, a dyeing procedure is adopted to dye the
fabric into a medium and light color elastic fabric. Then, the
fabric undergoes a second scutching procedure and a finished
product setting through a setting machine at temperatures from
150.degree. C. to 170.degree. C.
[0011] Dark Color Dyeing and Finishing Method: A fabric is
provided. The fabric comprises at least one elastic yarn. A ironing
machine is used to process the fabric. The fabric undergoes an
ironing procedure at temperatures from room temperature to
110.degree. C., 130.degree. C. and 150.degree. C., to maintain
warp-wise smoothness and flatness. After ironing, a sanforizing
machine is used to sanforize the fabric. Then after loosening, the
fabric undergoes a scutching procedure. Then, a setting machine is
used to preset the scutched fabric at temperatures from 180.degree.
C. to 195.degree. C. Then, a dyeing procedure is adopted to dye the
fabric into a dark color elastic fabric. After dyeing, the dark
color elastic fabric is put into a dye vat to undergo a washing
procedure. Then, the fabric undergoes a second scutching procedure
and a finished product setting through a setting machine at
temperatures from 120.degree. C. to 140.degree. C.
[0012] In this way, through the dyeing and finishing method for
elastic function textile fabrics disclosed in the present
invention, problematic situations like insufficient weft weight,
unsmooth fabric surface, pitting surface, uneven dyeing, side
shading, poor fastness, chromatic aberration, dyelot chromatism,
insufficient elasticity, as well as spray burns, etc can be
dramatically reduced. The improvements are detailed as below:
[0013] (1) Solution to insufficient weft weight: Generally, when an
elastic fabric undergoes a ironing procedure, the polyester fibers
may often become firm due to excessive warp pulling, over-speed, or
over-temperature. The invention uses a machine to loosen the fabric
at 120.degree. C. for 30 minutes after the fabric going through the
ironing machine. This can considerably reduce the problematic
situations of insufficient weft weight. [0014] (2) Solution to
unsmooth fabric surface and pitting surface: Situations like
unsmooth fabric surface and pitting surface may often occur due to
insufficient ironing temperature or over-speed when the elastic
fabric undergoes an ironing procedure during the dyeing and
finishing process. The invention reduces the ironing speed to 25
m/min to set the fabric, and thus can considerably reduce the
problematic situations of unsmooth fabric surface and pitting
surface. [0015] (3) Solution to uneven dyeing and side shading:
When dyeing elastic fabrics, uneven dyeing and side shading are
usually caused by such factors as dyeing heating curve, temperature
holding time, dosage of medicament, etc. By adjusting the heating
speed of the dyeing machine, the dyeing evenness of the elastic
fabrics can be improved.
