Technical Field

The invention belongs to the technical field of flannelette fabrics, relates to a three-dimensional napped cloth fabric and a preparation method thereof, in particular to a Greek flannelette fabric and a preparation process thereof, and discloses that the fabric can be used for manufacturing quilts, throw pillows, curtains, clothes and the like.

Background

With the development of the market and the continuous improvement of the living standard, people have higher and higher requirements on various fabrics, and the fabrics are required to have good heat retention property, better hand feeling, higher bulkiness and comfort degree and light ventilation.

The flannelette is a cotton fabric with a smooth and fluffy surface after napping, has strong stereoscopic impression, high glossiness, softness, thickness and good heat preservation performance, and is mainly used for manufacturing autumn and winter clothes, children clothes and the like. However, the traditional raising knitted fabric has consistent fluff directions, consistent light reflection and uniform cloth cover effect, the fabric of the traditional raising knitted fabric has poor pilling resistance, and the surface of a friction part or the surface of the fabric after being washed for many times is easy to raise and nodulate, so that the appearance is attractive, the service life of the fabric is also shortened, and resource waste is indirectly caused.

Therefore, the development of an attractive and antique three-dimensional napped fabric is a problem which needs to be solved urgently by the technical personnel in the field.

Disclosure of Invention

In view of the above, the present invention provides a three-dimensional plush fabric and a preparation method thereof, aiming at the problems existing in the prior art.

In order to achieve the above purpose, the invention provides the following technical scheme:

a preparation method of a three-dimensional napped fabric comprises the following steps:

(1) manufacturing a napped knitted fabric: knitting the fabric by a knitting machine to manufacture a raised knitted fabric;

the raised knitted fabric is warp-knitted raised fabric or weft-knitted raised fabric, wherein 75D/144F terylene DTY yarns are used for front carding of the warp-knitted raised fabric, and 40D/24F, 45D/24F or 54D/36F terylene DTY yarns are used for middle carding and rear carding to be made into the warp-knitted raised knitted fabric; the weft knitting fabric can also use 75D/144F terylene DTY yarn as pile yarn and 40D/24F, 45D/24F or 54D/36F terylene DTY yarn as ground knitting yarn.

(2) Presetting, napping and raising: pre-shaping and napping the napped knitted fabric prepared in the step (1) to obtain a blank;

(3) and (3) lustring and dyeing treatment: performing front and back surface lustring and dyeing treatment on the blank napped in the step (2) to obtain a flannel fabric primary product;

(4) and (3) post-treatment: and (4) carrying out rolling softening, sizing and packaging subsequent treatment on the dyed flannel fabric primary product in the step (3) to finally obtain the three-dimensional napped fabric.

The method comprises the following steps of dewatering and fabric arranging, rolling and softening, drying, finished product ironing and shearing, finished product shaping and quality inspection packaging, wherein the differences of the dewatering and fabric arranging, the rolling and softening, the drying, the finished product ironing and shearing, the finished product shaping and the quality inspection packaging are small compared with common flannelette, and the dewatering and fabric arranging is to remove dye liquor in dyed fabric and is the same as that of spin-drying clothes by a spin dryer; the rolling softening is to soak the flannelette with a softening agent and remove the softening agent liquid through rolling, and the softening of the fluff can be increased through the working procedure.

Preferably, the presetting temperature in the step (2) is 180-230 ℃; the height of the pile is 0.3-2.5 mm, and the speed of raising and rolling cloth is 20-25 m/min.

Further, the presetting process parameters are as follows: the preset vehicle is divided into eleven sections, the presetting temperature of the first section is 190 ℃, the presetting temperature of the second section to the tenth section is 220 ℃, and the presetting temperature of the eleventh section is 190 ℃; the height of the fluff is 0.5mm, and the speed of raising and rolling is 22 m/min.

Preferably, the lustring temperature in the step (3) is 118-122 ℃; and the ironing is performed in a reverse feather feeding mode, and the ironing is performed twice, specifically comprising the following steps: the first ironing roller is reversed to iron and straighten the fluff on the cloth surface; the second ironing roller rotates forwards to iron the fluff on the cloth surface.

Further, the rotating speed of the first ironing roller is 800 r/min; the rotating speed of the second ironing roller is 900 r/min.

Preferably, the dyeing process in the step (3) adopts a downward-moving high-temperature overflow dyeing machine, and the diameter of a nozzle of the high-temperature overflow dyeing machine is 60 cm.

Further, the dyeing adopts a reverse wool feeding mode, and the nozzle downwards punches along the direction of the wool; and during dyeing, the blank cloth in the dye vat is longitudinally driven by the rolling shaft, and the blank cloth is transversely randomly folded together.

Furthermore, the temperature rising rate of the blank cloth during dyeing is (1.2-1.5) DEG C/min, and the temperature reducing rate of the blank cloth during dyeing is (2.5-5) DEG C/min; and the temperature during dyeing is controlled between 40 ℃ and 140 ℃.

It should be noted that there are two kinds of high-temperature overflow dyeing machines, one is an upward-running type and the other is a downward-running type, and the downward-running type dyeing liquid has a large impact on the cloth surface. And the diameters of the nozzles of the high-temperature overflow dyeing machine are three, namely 100cm, 90cm and 60 cm. The common napping cloth is operated by two nozzles of 100cm and 90cm, and the Greek napping cloth is operated by a nozzle of 60 cm. The smaller the diameter of the nozzle, the greater the pressure of the dye liquor at the outlet of the nozzle, and the greater the impulse force on the lint. The high impact force created with a 60cm nozzle is advantageous for punching the pile on the pile fabric surface into an irregular orientation.

In addition, the Greek velvet fabric is dyed by adopting a down-feather progress, namely, when the cloth is fed, the fluff faces forwards, and the nozzle downwards punches along the direction of the fluff. When the Greek velvet fabric is dyed, the cloth is circularly rotated in a dye vat to be soaked with dye liquor, the cloth is longitudinally driven by a rolling shaft when being circularly rotated, and the cloth is transversely folded together (for example, the width of the cloth is 2.8 meters, the folds are fed in 0.5 meter), so when the cloth passes through a dye liquor nozzle, the fluff exposed on the surface is washed into a lodging state by the nozzle, and the fluff in the folds cannot be washed into the lodging state.

The folds of the cloth in the dye vat have randomness, so the orientation of the fluff on the cloth surface after dyeing also has randomness, the fluff has irregular orientation, the fluff reflecting intensity at the falling position is formed, the relatively vertical fluff has weak reflection, and the unique cloth surface effect of the Greek fluff fabric is formed.

Compared with the traditional preparation method of the common napped fabric, the preparation method of the three-dimensional napped fabric disclosed by the application has substantial differences and obvious technical effects as follows:

1) the presetting temperature of the application open protection is lower than ordinary gigging's presetting temperature, so that the fine hair that the cotton flannel surface fabric back-end napping machine pulled out is soft, further does benefit to the back-end dyeing process and makes irregular fine hair orientation.

2) Ordinary pile fabric needs secondary pre-setting, and the flannel surface fabric that this application discloses protection only needs primary pre-setting, can make the fine hair soft through primary pre-setting to make irregular fine hair orientation in the later process of dyeing.

3) The flannel fabric disclosed and protected by the application needs two ironing treatment, while the common raised fabric only needs one ironing treatment; in the step of dyeing the napped fabric by using a high-temperature overflow dyeing machine, a common napped fabric is generally sprayed with a dye solution by using a nozzle of 100cm or 90cm, the impact force of the dye solution is small, and meanwhile, the fabric is fed along the wool, and the dye solution is flushed against the direction of the wool, so that the wool is generally in an upright state; the application discloses and protects to adopt 60cm nozzle operation to do benefit to and break into irregular orientation with the fine hair on the gigging fabric surface, and adopt the fallen hair to advance the cloth when the fabric is dyed.

4) The utility model discloses intensification and cooling rate when the flannel surface fabric dyeing of protection all are faster than ordinary pile fabric, especially cooling rate, flannel surface fabric adopts faster cooling rate can make the cloth cover contract fast to the nozzle that makes the big impulsive force of minor diameter can be stereotyped better and remain at the fine hair of the irregular orientation of irregular yardage roll fold surface formation.

In addition, the direction of the fluff of the three-dimensional napped fabric prepared by the method is disordered, and the height of the fluff is 0.3-1.5 mm.

The fine hair direction through this application gigging looped fabric is disorderly on the whole, does not have fixed law. The irregular fluff orientation brings visual difference, the cloth cover can generate mottled effect, antique washing effect, old and romantic effect and the like, and the grade and the added value of the product can be improved.

The invention also discloses application of the three-dimensional napped fabric in the field of household articles or clothes. The fabric can be used for manufacturing quilts, throw pillows, curtains, clothes and the like.

Compared with the prior art, the invention discloses a three-dimensional napping cloth fabric and a preparation method and application thereof, and has the advantages that:

1) the invention innovatively develops a preparation method of a three-dimensional napped cloth fabric, the napped cloth fabric with disordered napping orientation can be obtained by the method, visual differences are brought by different light reflection caused by irregular napping orientation, the cloth fabric can generate visual effects of ice flowers, mottle and antique washing, the product grade and additional value can be improved, and the napped cloth fabric can be used for manufacturing quilts, throw pillows, curtains, clothes and the like, and is suitable for popularization and application in the market.

2) When the flannelette manufactured by the method disclosed by the invention is dyed, the blank cloth is transversely randomly folded together, and the dyeing liquid of the downward moving dye vat and the downward and smooth fluff impact with strong impact force and the special temperature rising and falling speed are combined, so that the orientation of the fluff on the cloth surface after dyeing has randomness, an irregular orientation of the fluff is formed, the fluff at the position where the fluff is impacted falls down has strong reflection, the relatively vertical fluff has weak reflection, and a unique cloth surface effect of the Greek flannelette is formed; and viewed from the longitudinal direction of the cloth, the overall reflective styles of the suede of the one-meter cloth and the next-meter cloth are the same, but are not completely the same, so that the natural and attractive requirements of consumers on the suede are finally met.
