Description

Preparation method of moisture-absorbing and quick-drying fabric
Technical Field
The invention belongs to the technical field and relates to a preparation method of a moisture-absorbing and quick-drying fabric.
Background
The traditional knitted fabric is generally woven by adopting a mode of blending all cotton or cotton and other cellulose fibers, the cellulose fibers have good hygroscopicity, and when a human body sweats a large amount, moisture on the surface of the human body can be quickly absorbed, but the moisture entering the fibers is difficult to evaporate because the cellulose fibers have too strong hydrophilicity and large migration resistance of the moisture in the fibers, and the side close to the skin can not quickly reach the outer side after absorbing the moisture, so the moisture can not be quickly evaporated; in addition, the frictional force between cellulose fibers after water absorption increases, and the stretchability of the fabric decreases when worn, resulting in a poor wearing experience.
In the prior art, a double-layer structure with a hydrophobic inner layer and a hygroscopic outer layer is generally designed to realize moisture absorption and quick drying of the fabric, particularly for controlling the hydrophobicity of the inner layer, hydrophobic fibers are selected, or the inner layer is subjected to hydrophobic finishing on the basis of the hydrophobic fibers, but the efficiency is still limited. The integral hydrophobic effect is not durable, and the hydrophobic membrane is easy to lose efficacy after multiple times of friction and washing; the most common way is to use profiled cross-section hydrophobic fibers, but the grooves of the general profiled cross-section fibers are on the same side, and the moisture-conducting efficiency of the profiled cross-section fibers needs to be further improved.
Therefore, the research on the moisture absorption quick-drying fabric with higher moisture conduction efficiency has very important significance.

As described abovePreparation method of moisture-absorbing and quick-drying fabric, wherein the gram weight of the moisture-absorbing and quick-drying fabric is 140-160 g/m2(ii) a Hygroscopicity (GB/T21655.12008): the water absorption rate is more than or equal to 250 percent, the drip diffusion time is less than or equal to 1.9 seconds, and the wicking height is more than or equal to 142 mm; quick drying (GB/T21655.12008): the evaporation rate is more than or equal to 0.38 g/h.
The principle of the invention is as follows:
the textured yarn fully drawn yarn is prepared according to an FDY process, high-viscosity PET and low-viscosity PET 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, the rest part is a skin layer, and in skin-core composite spinning, the distribution relation of a melt on the spinneret plate is as follows: the core layer corresponds to one melt I (high viscosity PET or low viscosity PET), and the skin layer corresponds to the other melt II (high viscosity PET or low viscosity PET); when two melts are extruded from the spinneret orifices 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 spinneret orifices are trilobal, so that the part of each leaf of the trilobal close to the circle center is the melt I, and the end of each leaf far away from the circle center is the melt II; cooling with a circular air blow while drawing to form fibers. When the fiber is in heat treatment, there will be a force effect on its cross section: the two components are arranged on each blade, and the thermal shrinkage rates of the two components are different, so that a drag force is formed on the blade, and the drag forces on the three blades face to the circle center or depart from the circle center simultaneously; moreover, because the trilobes of the trilobe spinneret orifice are not exactly equal in width, the drag on each lobe is different; the different drag forces make the high viscosity PET/low viscosity PET sheath-core composite monofilament in the fully drawn textured yarn present a twisted shape and have stable twisting performance, and on the basis of the twisting, a certain three-dimensional curling shape is formed.
Because the single fiber presents a special-shaped cross section (trilobal) structure, the fiber with the grooves can endow the fabric with good moisture absorption and moisture transmission performance (wicking action of capillary tubes generated by the grooves), particularly, when the fiber with the grooves is self-curled, the same groove is turned inwards and outwards, so that a part (usually the side facing the skin) which absorbs moisture firstly can be turned to the outer side (the side facing the air) through the guiding action of the grooves, compared with the special-shaped cross section fiber in the prior art (the grooves of the single fiber usually face to the same side), the moisture transmission efficiency of the textured yarn fully drawn yarn is higher; and the fiber has a twisted shape, the contact area of the fiber and the outer layer cotton fiber is larger, under the hydrophilic action of the cotton fiber, the moisture in the textured yarn fully drawn yarn is continuously absorbed by the cotton fiber, the contact area is larger, and the transmission efficiency of the moisture is also higher. Therefore, the moisture absorption and quick drying performance of the moisture absorption and quick drying fabric is improved on the whole.
