Description
Technical Field
The invention belongs to the technical field of textile fabrics, and relates to a preparation method of a carpet.
Background
At present, carpets are paved on the ground in many places to achieve noble and elegant decorative effects. The types of carpet are varied and include hand carpets, needle carpets, tufted carpets, Wilton carpets, Akming carpets, pattern carpets, modular carpets, and the like. Whether a tufting loom or a rapier loom is used to process the carpet, BCF is required as the raw material.
Since the BCF production technology is industrialized, the BCF raw materials are mainly Polyamide (PA) and polypropylene (PP) in the world, and polyester is rarely adopted. The PBT polyester has more comfortable wool-type hand feeling, the carpet fluff has certain resilience (resilience) after being pressed, the properties make the PBT polyester particularly suitable for manufacturing carpets besides being used as plastics, but the resilience of the PBT polyester carpets is far lower than that of PA carpets, and the application of the PBT polyester carpets is greatly limited.
Therefore, the research on the preparation method of the carpet with better rebound resilience is of great significance.
Disclosure of Invention
The invention provides a preparation method of a carpet, and aims to solve the problem that in the prior art, a carpet made of polyester such as PBT is far lower in resilience than a carpet made of PA.
In order to achieve the purpose, the invention adopts the following scheme:
a preparation method of a carpet comprises the steps of firstly arranging and warping carpet yarns and polyester yarns to obtain warps, then carrying out loop buckling treatment on the warps, then weaving the warps and the loops treated warps by taking the carpet yarns as wefts to obtain base cloth, finally implanting the carpet yarns into the front side of the base cloth through tufting, coating polyester hot melt adhesive on the back side of the base cloth, and cooling to obtain the carpet;
all carpet yarns were prepared as follows:
in the process of preparing the circular sheath-core composite fiber from PBT and PTT according to the BCF process, the spinneret holes on the spinneret plate are changed into trilobal from circular, circular air blowing is adopted for cooling, and the arrangement of the trilobal spinneret holes on the spinneret plate is controlled to meet certain conditions, so that carpet yarn is prepared;
the length ratio of three leaves of the same trilobal spinneret orifice is 1.0: 1.1-1.4: 2.0-2.5, the width ratio of the corresponding three leaves is 1:1.5:1.5, the length ratio of the shortest leaf to the width ratio is 2.5-3.5: 1, and the included angle of the central lines of two adjacent leaves is 120 degrees; the three leaves of different trilobal spinneret orifices have the same shape and size;
the certain conditions are as follows: all the trilobal spinneret orifices are distributed in concentric circles, and the center line of the shortest blade of each trilobal spinneret orifice passes through the circle center and points away from the circle center.
The principle of the invention is as follows:
the carpet is prepared by implanting carpet yarn into the front side of base fabric through tufting, coating polyester hot melt adhesive on the back side of the base fabric, and cooling, wherein the base fabric is prepared by firstly arranging and warping the carpet yarn and polyester yarn to obtain warp, then carrying out loop-buckling treatment on the warp, then taking the carpet yarn as weft, and weaving the weft together with the loop-buckled warp;
all carpet yarns are sheath-core composite fibers prepared by taking PBT and PTT as raw materials according to a BCF process, the PBT and the PTT are extruded from trilobal spinneret orifices on the same spinneret plate, an imaginary circle is made around the center of the trilobal, the part of the trilobal, which is coincided with the imaginary circle, is a core layer, and the rest part is a skin layer, and in sheath-core composite spinning, the distribution relation of melts on the spinneret plate is as follows: the core layer corresponds to one melt I (PBT or PTT), and the skin layer corresponds to the other melt II (PBT or PTT); when two melts are extruded from the spinneret orifice under the action of spinning pressure, the melt I is mainly extruded from the core layer, the melt II is mainly extruded from the skin layer, and the section of the spinneret orifice is trilobal, so that the part of each leaf of the trilobal close to the center of a circle is the melt I, and the end of each leaf far away from the center of a circle is the melt II; cooling with a circular air blow while drawing to form fibers. When the fiber is subjected to heat treatment, there is a force effect on its cross section: the PBT component and the PTT component are arranged on each blade, the thermal shrinkage rates of the PBT component and the PTT component are different, so that a drag force is formed on the blade, and the drag forces on the three blades face to or depart from the center of an imaginary circle simultaneously; moreover, because the three leaves of the trilobal spinneret orifice are unequal in length and not completely equal in width, drag force on each leaf is different; this differential drag causes the PBT/PTT sheath-core composite filaments in the resulting carpet yarn to exhibit a twisted morphology (twist angle per unit length)45 to 128 DEG/10 μm of (l is the length of the fiber segment with the number of turns of 1 in μm)), and the twisting performance is stable, in the twisted stateOn the basis, a certain three-dimensional crimp shape is formed, so that the compression resilience of the household carpet made of the carpet yarn is greatly increased. In addition, due to the existence of the capillary grooves among the three-leaf profiled fibers, the household carpet prepared from the three-leaf profiled fibers has better water absorption performance; the raw materials used in the preparation process of the carpet are all polyester, are convenient to recover and have very important environmental protection value.
