Description
Technical Field
The invention belongs to the field of fabric shaping, and particularly relates to a shaping process of an FDY flame-retardant polyester filament fabric.
Background
With the stricter requirements of the downstream market of textiles on the environmental protection performance of products, the monitoring strength of the printing and dyeing industry on the environmental protection production is also stricter, and the energy conservation and emission reduction become the key points of the long-term development of the printing and dyeing industry. For a long time, the traditional polyester printed flame-retardant cloth must be added with a brominated flame retardant through coating finishing, and the flame retardant can be permeated into the fabric to achieve the flame-retardant effect.
After long-time use, folding and washing, the flame-retardant coating on the surface of the fabric can generate creases, and meanwhile, the coating can generate cracks, so that the flame-retardant coating falls off, or the flame-retardant coating loses the flame-retardant effect.
Disclosure of Invention
The invention provides a sizing process of an FDY flame-retardant polyester filament fabric, which is characterized in that a water-based flame retardant is attached to fabric yarns in a padding mode, and a self-crosslinking film and a fiber crosslinking film are formed on the surfaces of the fabric yarns after drying, so that the fabric has a flame-retardant effect.
The specific technical scheme of the invention is as follows: a shaping process of an FDY flame-retardant polyester filament fabric comprises the following steps: (1) raising the two sides of the fabric, namely erecting short piles on the two sides of the fabric in an electrostatic adsorption mode;
(2) firstly, soaking and rolling, namely soaking the fabric into the water-based flame retardant for the first time, and then performing the first calendering through a roller;
(3) secondary raising, rolling on the surface of the fabric through an electrostatic roller, and standing the untightened short piles again;
(4) soaking and rolling for the second time, soaking the fabric into the water-based flame retardant for the second time, and calendering for the second time after passing through the roller again;
(5) and (4) drying, namely soaking the fabric subjected to secondary calendering into a dryer for drying.
Firstly raising, erecting the short piles on the two sides of the fabric in an electrostatic adsorption mode to reduce the coverage of the short piles on the fabric yarns, and secondly, soaking and rolling to facilitate the adhesion of a water-based flame retardant on the surfaces of the yarns, wherein static electricity is guided out in the soaking process, and after the short piles are erected, the water-based flame retardant is adhered on the surfaces of the yarns, so that the short piles penetrate into the water-based flame retardant layer, and a self-crosslinking film and a fiber crosslinking film are formed on the surfaces of the fabric yarns after drying, so that the fabric has a flame retardant effect, and meanwhile, after the crosslinking film is formed, the flame retardant layer on the outer surface of the fabric yarns is firmly combined with the fibers and is not easy to fall off; the thickness of the water-based flame-retardant layer after the first soaking and the first rolling is smaller than the length of the short velvet, so that the short velvet is raised for the second time after the first soaking and the first rolling, the short velvet is integrally crosslinked inside the water-based flame-retardant layer after the second soaking and the second rolling, and the flame-retardant layer can be kept intact after the short velvet is dried and washed for multiple times, so that the water-based flame-retardant layer is ensured to have enough flame-retardant performance; the secondary raising adopts a mode of rolling by an electrostatic roller, and is also used for controlling the direction of electrostatic attraction short hair.
Preferably, when the fabric is napped on both sides, brushing is carried out on the surface of the fabric by using a brush, and then the fabric is brushed by using a suspended electrostatic adsorption mode; and during secondary napping, the electrostatic roller is attached to the surface of the fabric and rolls on the surface of the fabric, and the rolling direction of the electrostatic roller is opposite to the rotating direction of the roller during one-time soaking and one-time rolling. During raising, the hair brush is firstly used for brushing the hair, so that short hair can be combed, knotting and other phenomena can be avoided, and meanwhile, attached yarn and hair can be removed; during secondary raising, static roller laminating fabric surface, the tip distance with the short pile is short this moment, and secondary raising is effectual, and the roll reversal of static roller is opposite with the rotation direction of roll, and the effect that the short pile erects like this is better, and the electrostatic adsorption power of secondary raising generally can be greater than the electrostatic adsorption power of first raising.
Preferably, the pressure of the roller is controlled at 0.35MPa, the liquid carrying rate is controlled at 40-45% and the overfeeding is controlled at-0.5% during the first soaking and the first rolling. When padding for the first time, the pressure of the roller is a little greater, the thickness of the flame retardant layer formed for the first time is a little smaller, the liquid carrying rate is a little smaller, the flame retardant layer is dry, and after overfeeding, the radial stretching of the fabric is improved, so that the water-based flame retardant can penetrate into warp and weft gaps of the fabric during padding.
Preferably, the pressure of the roller is controlled at 0.25MPa, the liquid carrying rate is controlled at 60 percent, and overfeeding is carried out at-0.1 percent during the two-dipping and two-rolling. And during the second padding, the pressure of the roller is slightly smaller, the thickness of the flame-retardant layer is slightly increased, and the flock is fully covered, so that the liquid carrying rate is slightly higher in consideration of drying.
Preferably, the aqueous flame retardant comprises aqueous polyurethane and aqueous polyacrylate, and the ratio of the aqueous polyurethane to the aqueous polyacrylate to the water is controlled to be 3:1: 6. After two times of padding, the surface of the yarn is stained with aqueous polyurethane liquid, and after drying, the aqueous flame-retardant layer is crosslinked into a film.
Preferably, after the two-dipping and two-rolling, the fabric enters a dryer, the temperature of the dryer is controlled to be 215 ℃ and 230 ℃, and the speed of the dryer is controlled to be 70 m/min.
The invention has the beneficial effects that: raising, namely erecting the short piles on the two sides of the fabric in an electrostatic adsorption mode to reduce the coverage of the short piles on the fabric yarns, conveniently attaching a water-based flame retardant to the surfaces of the yarns during the second step of soaking and rolling, and simultaneously leading out static electricity during the first step of soaking, wherein the water-based flame retardant is attached to the surfaces of the yarns after the short piles are erected, so that the short piles penetrate into the water-based flame retardant layer and form a self-crosslinking film and a fiber crosslinking film on the surfaces of the fabric yarns after drying, and therefore, the fabric has a flame retardant effect; the thickness of the water-based flame-retardant layer after the first soaking and the first rolling is smaller than the length of the short velvet, so that the short velvet is raised for the second time after the first soaking and the first rolling, the short velvet is integrally crosslinked inside the water-based flame-retardant layer after the second soaking and the second rolling, and after drying, the flame-retardant layer can be kept intact after multiple times of washing, and the enough flame-retardant performance is ensured.
