A kind of preparation method of Roman cloth

technical field

The invention relates to the technical field of textile preparation, more specifically, it relates to a method for preparing Roman cloth.

Background technique

Roman cloth is a kind of knitted fabric woven by a large circular machine, commonly known as chicken cloth. The cloth surface of Roman cloth is not as smooth as ordinary double-sided cloth. Strong, used to make close-fitting clothing, breathable, soft and comfortable to wear.

Nylon has good wearing properties such as excellent strength, abrasion resistance, soft hand feeling and light texture. At the same time, nylon fabric has a high moisture regain rate of 4.5%-7%, which is a commonly used fiber material for Roman cloth; spandex has excellent elasticity and strength. High acid and alkali resistance, sweat resistance, sea water resistance, dry cleaning resistance, abrasion resistance are good. Due to the excellent properties of nylon and spandex, blended fibers of nylon and spandex are often used in Roman cloth. Nylon/spandex blended Roman cloth has good moisture absorption effect, good horizontal and vertical elasticity, and is wear-resistant and sweat-resistant.

At present, the Chinese invention patent with the publication number CN104818570A discloses a knitted all-nylon roman cloth and its production process, which belongs to the technical field of textile fabrics, and is woven from twisted yarns of 70D nylon and 40D spandex, or It is woven with 50D nylon and 40D spandex twisted yarn, which specifically includes the following steps: Weaving 70D nylon and 40D spandex twisted yarn into gray fabric, or weaving 50D nylon and 40D spandex The twisted yarn is woven into gray fabric→unwinding→cold stacking→leveling→scheduling→pretreatment→dyeing→opening→drying→finished product shaping→rolling and packaging, in which acid dyes are used in the dyeing process.

Because Roman cloth is often used as underwear, the requirements for color fastness are relatively high. The color fastness of nylon dyed with traditional acid dyes is between 3 and 4. Underwear is easy to fade when it rubs against the outer clothes and is affected by sweat stains. Stains outer clothing.

Contents of the invention

Aiming at the deficiencies in the prior art, the object of the present invention is to provide a method for preparing Roman cloth, which solves the problems that Roman cloth is rubbed and sweat stains are easy to fade by adopting alkali training twice, adding dyes in batches and color fixing , which has the advantages of improving the color fastness to rubbing and perspiration of Roman cloth.

To achieve the above object, the present invention provides the following technical solutions:

A preparation method of Roman cloth, comprising the following steps:

(1) Yarn pretreatment: After soaking nylon and spandex yarns in lye for a period of time, take them out and clean them;

(2) Steam setting: put nylon and spandex yarns in a steam tank, fill the steam tank with steam after vacuuming, keep the temperature of the vacuum tank at 100-120°C for 50-80 minutes;

(3) Weaving nylon and spandex into gray cloth by large circular knitting machine;

(4) Gray cloth pre-treatment: soak the gray cloth with lye, take it out and wash it, shape and singe the gray cloth;

(5) Dyeing: Add dye auxiliaries and the first dye to the dye vat, start to heat up at room temperature, the heating rate is 1-1.5°C/min, heat up to 60°C, keep warm for 30-50min, add dye auxiliaries and the second dye, Raise the temperature to 90°C at a speed of 1-2°C/min, keep it warm for 20-30min, and slowly cool down to 40-50°C at a speed of 1.5-2°C/min, take it out and wash it;

(6) Color-fixing treatment: after padding the washed gray cloth in the color-fixing finishing solution, dry it;

(7) After-finishing: pad the gray cloth in the finishing solution, the finishing solution includes softener and antistatic agent, the temperature is 40-45°C, the padding time is 10-20min, and then the gray cloth is passed through a heat setting machine for 170- 180°C, machine speed 40r/min, and proper overfeeding to shape the gray cloth;

(8) Inspection, rolling and packaging to obtain Roman cloth.

Through the above-mentioned technical scheme, step (1) and (4) two alkali exercises can remove the oil stains, color stains and impurities attached to the yarn and gray cloth, reduce the impact on subsequent dyeing, and reduce the appearance of color flowers and color spots; dyeing During the process, by slowly heating up and stepwise heat preservation and adding dyes in batches, the dyeing speed of the dyes is slowed down and the dyeing is more uniform; the color fastness of the gray cloth is improved by the color fixing treatment after dyeing; The after-finishing of the fabric eliminates the defect that the color-fixing agent makes the fabric feel hard, and the Roman cloth prepared by the invention is not easy to fade under the influence of friction and perspiration, and has good color fastness.

As the dyeing auxiliaries, lignosulfonic acid sodium salt and glacial acetic acid can be used, and other auxiliaries conventional in the art can also be used.

It is further preferred that the alkali solution concentration in the step (1) is 220-250g/L, the initial temperature is controlled at 40°C, and then the temperature is slowly raised to 80°C at 2°C/min, kept for 50 minutes, taken out, washed and dried.

Through the above technical scheme, the caustic soda solution can degrade the oil stains and dissolve the oil stains, and improve the oil removal effect. Controlling the water temperature at 40°C can reduce the damage of the alkali solution to the fiber under high temperature conditions; at the same time, the alkali solution will partially dissolve the fiber surface and release the dyed spots. And make the fiber rough, which is convenient for the subsequent dyeing of the fiber, and it is not easy to fall off. The rough surface of the fiber can also avoid slipping and stripping, and improve the hand feeling.

Further preferably, the step (4) specifically includes: padding the gray cloth woven from the yarn into lye, controlling the water temperature at 40°C, adding lye, and the lye includes 100-150g/ L. Penetrating agent 50-60g/L and caustic soda 220-250g/L, then slowly raise the temperature to 80°C at 2°C/min, keep warm for 50min, take it out, wash and dry it, set the rough billet into a tenter shape, and adjust the speed to 40r /min, singeing the gray cloth.

Wherein the degreaser is the emulsified degreaser TF-115D of Zhejiang Transfar Co., Ltd., and the penetrant is the penetrant FFA.

Through the above technical scheme, the degreaser can remove the oil stains, color stains and impurities attached to the yarn, the penetrant assists the degreaser to penetrate into the fiber, the lye can degrade the oil stain and dissolve the oil stain, and improve the degreasing effect. The temperature is from 30- The temperature rises slowly at 40°C to reduce the damage of lye to the fiber under high temperature conditions; at the same time, the lye will partially dissolve the surface of the fiber, release the dyed spots and make the fiber rough, which is convenient for the dye to dye the fiber, not easy to fall off, and the fiber surface is rough. Avoid slipping and stripping, and improve the hand feeling.

Further preferably, in the step (5), the first dye is a low-temperature disperse dye, and the second dye is an acid dye.

Through the above technical scheme, the compatibility of disperse dyes is better, and the molecules of low-temperature disperse dyes are small, and it is easy to dye the inside of the fiber. First, the disperse dyes are combined with the fibers through van der Waals force. The disperse dyes first adhere to the surface of the fibers, and as the temperature increases , the chain segment movement of the fiber, the disperse dye enters the interior of the fiber, and the acid dye is added later, and the acid dye dyes the nylon through the ionic bond and van der Waals force, which has a saturation point, and the acid dye further dyes the fiber and combines with the fiber, so that the acid dye and the fiber The combination fastness is high, the acid dyes on the surface are not easy to fall off, and the disperse dyes inside the fiber are not easy to fall off, which enhances the color fastness of Roman cloth to rubbing and perspiration.

Low-temperature disperse dyes adopt conventional disperse dyes in the field, such as disperse orange 80, disperse red 82, disperse blue 148, and disperse blue 366; acid dyes use conventional acid dyes in the field, such as acid red 37, acid red 89, Acid red 145, acid yellow 42, acid yellow 49, acid blue 215, acid blue 277, acid blue 344.

More preferably, the color-fixing finishing solution used in the step (6) is polymethylacrylate, the concentration is 70-80g/L, and the viscosity is 1000Cs.

Through the above-mentioned technical scheme, polymethyl acrylate has good film-forming properties, high transparency and excellent friction resistance, which can firmly fix the dye to the fabric without affecting the color of the dye, and it is easier to use polymethyl acrylate with a smaller molecular weight. Into the fiber, to achieve the coating of a single fiber, improve the color fastness of the fabric, and at the same time, the coating of a single fiber has little effect on the hand feeling of the fabric.

More preferably, in the step (6), the gray cloth is dipped and rolled in the color-fixing solution, prebaked at 60°C for 5-15 minutes, and then baked at 120°C for 10-20 minutes.

Through the above technical scheme, low-temperature pre-drying is to reduce the moisture content of the fabric, avoid the dyes that have dyed the fabric from migrating, and cause color patterns on the surface of the fabric; high-temperature baking makes polymethylacrylate flow on the surface of the fiber, which can be better At the same time, the chain segment of the fiber at 120°C moves, which facilitates the further migration of the dye to the interior of the fiber, and at the same time facilitates the penetration of the color fixing agent into the interior of the fiber.

Further preferably, the color fixing solution in the step (6) further includes urea, and the concentration of the urea is 10-20 g/L.

Through the above technical scheme, urea can promote the penetration of the color fixing agent into the fiber.

Further preferably, the color fixing treatment in the step (6) is carried out in a vacuum steam box, the color fixing liquid is mixed into the steam, and the temperature is controlled at 120°C.

Through the above technical scheme, the color-fixing agent can penetrate into the fiber more easily to cover a single fiber, and at the same time can improve the strength of the fiber; the color-fixing agent forms a film on the surface of the fiber to improve the smoothness of the fiber surface, thereby improving the bright color of the fabric In addition, the process flow is shortened and the production efficiency is improved.

More preferably, the softener in the finishing liquid is a silicone softener with a concentration of 220-250 g/L, and the antistatic agent is an alkyl phosphate diethanolamine salt with a concentration of 80-90 g/L.

Through the above technical proposal, the silicone softener can give the Roman cloth a soft feel, and the antistatic agent can make the Roman cloth have an antistatic effect.

In summary, compared with the prior art, the present invention has the following beneficial effects:

(1) In the pretreatment process of fabric yarn and gray cloth in steps (1) and (4), not only the oil stains, color stains and impurities on the surface of the fabric are removed, but also the local degradation of the fiber by the lye makes the yarn During the process, the mutual embracing is more firm, and it is not easy to take off and slip. At the same time, the gap between the fibers is increased and more dyeing points are released, which is convenient for the dye to penetrate into the interior and dye through ionic bonds and van der Waals force. fiber, improve the color fastness to rubbing and perspiration of Roman cloth;

(2) During the dyeing process in step (5), by adding dyes in batches, slowly raising the temperature and keeping warm in stages, it is beneficial to avoid the problem of uneven dyeing caused by too fast dyeing rate in the early stage of dyeing. At the same time, compatibility is added in the first stage Good and small molecular weight disperse dyes, adding acid dyes with high affinity with nylon fabrics in the second stage is beneficial to improve the dye uptake rate, and the dyed fibers with small molecular weight disperse dyes are not easy to fall off, and the combination of acid dyes on the fiber surface and fibers is firm High density, not easy to fall off, improving the color fastness of the fabric;

(3) After dyeing, use polymethyl acrylate to fix the color of the fabric. The color fixing agent forms a film on the surface of the fiber, which can not only improve the color fastness of the dye, but also improve the smoothness and fiber strength of the fiber surface.
