Description
Technical Field
The invention relates to the technical field of textile fabrics, in particular to a preparation method of superfine fiber spunlace non-woven fabric.
Background
The textile industry of China considers that the fiber with the monofilament fineness less than 0.44dtex is defined as superfine fiber, and most of the superfine fiber can be prepared by combining the fiber. The superfine fiber is made of terylene, chinlon, polypropylene, viscose, spandex, etc. and is mainly made of filament and staple fiber. The production method of the ultrafine fiber filament generally includes a direct spinning improvement method, a high-molecular mutually parallel spinning method, a stripping type composite spinning method, a multilayer conforming spinning method and the like; the methods of the superfine short fiber mainly include a spray melting method, a flash spinning method, a blending spinning method and the like.
The superfine fiber is made into knitted fabric, woven fabric or non-woven fabric, and then is sanded or napped, then is soaked in polyurethane solution, and then is dyed and finished to make imitation leather or artificial leather fabric, and can be compared with natural leather in the aspect of physical property, so that it becomes the best material for replacing natural leather.
Chinese patent CN111041850A discloses a preparation method of aqueous superfine fiber synthetic leather, which comprises the following steps: 1) coating a water-based hydrophobic auxiliary agent on the surface of the sea-island fiber non-woven fabric, and then drying and curing to obtain a base fabric A subjected to surface hydrophobic pretreatment; 2) uniformly soaking the base cloth A into the water-based polyurethane impregnating resin, fully impregnating the base cloth A through a roller, and then drying and curing to obtain a composite base cloth B; 3) carrying out alkali decrement, water washing, acid neutralization and drying treatment on the composite base cloth B, and removing a sea component and a hydrophobic auxiliary agent in the composite base cloth B to obtain superfine fiber base cloth C; 4) and (3) carrying out sanding, dyeing and softening treatment on the superfine fiber base cloth C to obtain the water-based superfine fiber synthetic leather with gradient distribution of polyurethane impregnated resin. However, the synthetic leather prepared in this patent has poor moisture permeability.
Chinese patent CN110306353A discloses a multi-dimensional superfine fiber synthetic leather and a preparation method thereof, wherein the multi-dimensional superfine fiber synthetic leather is composed of multi-dimensional superfine fibers and polyurethane, multi-dimensional sea-island superfine fibers with reduced sea component content of 10% -18% are prepared, the prepared sea-island fibers are processed into non-woven fabrics, the non-woven fabrics are soaked in polyurethane resin slurry, the multi-dimensional superfine fiber synthetic leather base fabrics are obtained through solidification, reduced fiber opening, water washing and drying and shaping, and the base fabrics are subsequently processed to obtain the multi-dimensional superfine fiber synthetic leather. However, the multi-dimensional superfine fiber synthetic leather prepared by the patent has poor hand feeling and poor simulation.
Disclosure of Invention
The invention aims at the problems and provides a preparation method of superfine fiber spunlace non-woven fabric.
The technical scheme adopted by the invention for solving the problems is as follows: a preparation method of superfine fiber spunlace non-woven fabric comprises the following steps:
step S10, the orange segment fibers are put into a carding machine to be carded into a net, and the surface density is selected to be 60g/m2Sequentially carrying out ultrasonic treatment, pre-spunlace, main spunlace, drying and winding on the fiber web to obtain superfine fiber base cloth; the working parameters of the ultrasonic treatment are as follows: the ultrasonic power is 300-500W, and the ultrasonic temperature is 35-45 ℃;
step S20, placing the superfine fiber base cloth obtained in the step S10 into a horizontal drum type washing machine, washing for 5-8 hours, and ironing and shaping at 120-140 ℃ to obtain a pretreated base cloth;
and step S30, immersing the pretreated base fabric into the coating liquid, controlling the bath ratio to be 1:30, and the time to be 6-10 minutes, and then solidifying, reducing and drying to obtain the superfine fiber spunlace non-woven fabric.
The spunlace method does not use chemical reagents, has little damage to fibers, can ensure that the prepared product has good mechanical and physical properties and hand feeling, can greatly simplify production procedures and reduce components, and fully exerts another property specific to the superfine fibers; the acting force of the washing machine on the spunlace non-woven fabric is far less than that of the spunlace process, the acting temperature is mild, the loss on fibers is small, the fiber forming rate can be improved through the action of long-time weak mechanical force, the fibers are split into finer fibers, the entanglement among the fibers is tighter, the internal pore structure of the non-woven fabric is more uniform and compact, and the air permeability of the product is improved; the ultrasonic pretreatment can reduce the damage of the fiber and lead the fiber to be split more thoroughly.
Further, in step S10, the orange peel fiber is composed of polyamide/polyester, and the ratio of polyamide to polyester is 43-65: 35-57, and the number of completely split petals is 16.
Further, in step S10, the pressure of the pre-hydroentangling is 25 to 30 bar.
Further, in step S10, the pressure of the primary spunlace is 70 to 80bar, and the number of primary spunlaces is 5 to 8.
The pre-spunlace prewets the fiber web, the impact effect of water on the fiber web is small, fibers are prevented from being entangled, the main spunlace pressure is high, the fibers are reflected, displaced and entangled under large impact, split fibers are separated into single fibers, and the scientific and reasonable spunlace pressure and channel number can achieve ideal fiber entanglement and fiber splitting effects.
Further, in step S20, the pretreated base fabric has a single fiber linear density of 0.05 to 0.25 dtex.
Further, in step S30, the modified polyurethane content in the coating liquid is 18 to 26%.
Furthermore, the impregnation amount of the modified polyurethane is 40-75% of the dry weight of the pretreated base cloth.
