The cool polyester and the hydrophilic polyester in the embodiment of the invention are obtained by adopting commercial yarns, and the mass ratio of the cool polyester to the hydrophilic polyester is preferably 45-50: 50 to 55. For example, the yarn specification of the cool polyester can be F75D/36F, except that the cool function and other parameters are not different from those of the common polyester; the hydrophilic polyester has 75D/36F full extinction, low-temperature dyeing and environmental protection.
The invention mainly realizes the purpose of unidirectional moisture guiding by adopting energy-saving and emission-reducing yarn selection and double-layer fabric structure application. The embodiment of the invention adopts a conventional round weft knitting machine to weave the cool polyester and the hydrophilic polyester according to double-sided tissues, and the special double-layer structure fabric is obtained after the weaving.
The double-layer structure fabric woven by the embodiment of the invention is basically pure terylene, the surface layer is a weft knitting jacquard structure, generally similar to a jacquard structure such as meshes or grids, and the bottom layer is a plain weave structure.
In the embodiment of the invention, the double-layer structure fabric has loose intervals among yarns of a bottom structure relatively, and the intervals among the yarns after weaving cannot be very tight, so that the follow-up processing is facilitated; the index having a relatively large correlation is referred to as the cross density (WPC) and the longitudinal density (CPC), and is related to the number of stitches, the stitch length, the yarn thickness, and the like. The transverse density is the number of stitches in the transverse direction of the knitted fabric within a predetermined length, the longitudinal density is the number of stitches in the longitudinal direction of the knitted fabric within a predetermined length, and the weft knitted fabric is generally 5cm in the predetermined length. The present invention preferably has a transverse density of 66 and a longitudinal density of 104; if the structure of the bottom layer is too tight, moisture does not easily pass through the yarn layer on the bottom surface, and perspiration effect is reduced. If terylene and spandex blended materials are adopted, the combination can increase the gram weight of the product to a certain extent, and the quick-drying index and the like of the materials can be influenced.

Wherein, the preshaping is carried out by a setting machine, so as to prepare for subsequent dyeing. The preferred pre-shaping process may be: clear water passing through the padder, setting machine temperature of 180-190 ℃, vehicle speed of 18-30 m/min, overfeeding of 15%, and liquid carrying rate of 75-100%. As the terylene in the fabric is hydrophilic terylene, the hand feeling becomes hard after high temperature, so the setting temperature cannot be higher than 190 ℃. In addition, the embodiment of the invention can also carry out technological processes such as refining and the like before the pre-shaping.

The dyeing bath formula preferably adopts 0.1-5% owf disperse dye; dispersing agent and acetic acid are also added, and the pH value of the dye liquor is controlled to be 5-7. The dispersing agent is preferably aromatic carboxylic monoester with the concentration of 0.5-2 g/L; the dosage of acetic acid can be 0.5-2 g/L. Since the solubility of disperse dyes (such as azo type and anthraquinone type structures) in water is extremely low, dye liquor is formed by adding the dye and a dispersing agent in the solution; in order to prevent the disperse dye and polyester from hydrolysis under the action of high temperature and alkali, the dyeing of the disperse dye is usually carried out under the weak acid condition.
The embodiment of the invention can adopt an overflow dyeing machine to carry out high-temperature high-pressure overflow dyeing, and the pressure can be 2-4kg/cm 2 After dyeing, water washing and other treatments are carried out; the reduction cleaning is carried out to replace soaping when the dyeing is dark, so that the color of the dyed finished product can be kept bright. In some embodiments of the invention, the dyed dye liquor is discharged, and the reduction cleaning is continued, wherein the reduction cleaning bath ratio is 1: 10-20, heating to 80 ℃, preserving heat for 10-30 min, and draining. Preferably, the reduction cleaning liquid includes: 0.3 to 0.5g/L of sodium carbonate and 1 to 3g/L of reducing agent, wherein the reducing agent is sodium hydrosulfite or thiourea dioxide.
Other embodiments of the present invention may employ conventional post-bleaching treatments; the invention does not need to add moisture absorption and perspiration auxiliary agent in the finishing process after dyeing and bleaching, and belongs to a more environment-friendly one-way moisture guiding technology.
After dyeing, the obtained dyed fabric is dried and shaped, wherein the drying temperature is preferably 150-180 ℃, and more preferably 155-170 ℃; the drying speed can be 10-20 m/min. After the drying and shaping are finished, a finished product of the cool unidirectional moisture-conducting fabric (namely, the cool unidirectional moisture-conducting fabric with the gram weight of 150g/m can be obtained 2 )。
