Problems solved by technology

Although this patent application scheme can embody the technical effect described in column 0026 to column 0030 of its description to a certain extent, it also has the following shortcomings: First, since the gray cloth needs to be put into the cylinder in the fabric pretreatment step, the overflow jet is introduced. The pre-treatment is carried out in the dyeing machine, so the process is more cumbersome and increases the processing cost; second, due to the difficulty in the source of cool nylon fiber FLYCOOL raw materials and the high price, the price of the finished fabric is difficult to meet the needs of mass consumption

Embodiment 1

[0024] A) Weaving, the silk made of hydrophilic fibers (spun) is used as the surface texture, and the silk made of water-repellent fibers (spun) is used as the bottom structure, and the gray cloth is obtained by weaving through a double-sided large circular machine, wherein: Hydrophilic fiber is hydrophilic polyester filament, which accounts for 50% by mass in the fabric (that is, the mass percentage of hydrophilic fiber accounts for 50% of the total composition, the same below), and water-repellent fiber is repellent Water-based polyester filaments account for 50% by mass in the fabric (that is, the mass percentage of water-repellent fibers accounts for 50% of the total composition, the same below), and hydrophilic polyester filaments are preferably used without limitation. The high hydrophilic polyester filament produced and sold by Invista Corporation of the United States is COOLMAX, and the water-repellent polyester filament is also preferably but not limited to the brand...

Embodiment 2

[0031] A) For weaving, only the mass percentage of hydrophilic polyester filament is changed to 70%, and the water-repellent fiber is changed to cotton fiber, and the mass percentage in the fabric is changed to 30%;

[0032] B) Pre-treatment, only change the amount of degreaser to 0.5g / L, the speed of the gray cloth to 9m / min, the temperature of the water tank to 80°C, and the pH value to 9;

[0033] C) Pre-setting, only change the pre-setting temperature to 170°C and cloth speed to 10m / min;

[0034] D) For dyeing, change the heating rate to 1.5°C / min and raise the temperature to 140°C, change the holding time at 140°C to 35 minutes, and change the cooling rate to 1.5°C / min;

[0035] E) After finishing, only change the drying temperature to 110°C, the cloth speed to 20m / min, and the amount of softener to 3g / L.

[0036] The content not mentioned in this embodiment is the same as the description of Embodiment 1.

Embodiment 3

[0038] A) For weaving, only the mass percentage of hydrophilic polyester filament is changed to 60%, and the water-repellent fiber is changed to a mixed fiber of wool fiber and hemp fiber, and the mass percentage of the fabric is changed to 40%, the mass percentage of wool fiber and hemp fiber is 50% respectively;

[0039] B) Pre-treatment, only change the amount of degreasing agent to 3.5g / L, change the gray cloth traveling speed to 15m / min, change the temperature of the water tank to 90°C, and change the pH value to 8;

[0040] C) Pre-setting, only change the pre-setting temperature to 180°C and cloth speed to 20m / min;

[0041] D) For dyeing, change the heating rate to 1.2°C / min and raise the temperature to 120°C, change the holding time at 120°C to 30 minutes, and change the cooling rate to 1.2°C / min;

[0042] E) After finishing, only change the drying temperature to 120°C, the cloth speed to 30m / min, and the amount of softener to 2g / L.

Abstract

The invention relates to one-way moisture-guiding knitted double-faced fabric and a processing method thereof, belonging to the technical field of knitted fabric. The one-way moisture-guiding knitted double-faced fabric comprises a face structure and a bottom structure, wherein the face structure is made of hydrophilic fiber and the bottom structure is made of hydrophobic fiber. The processing method comprises the following steps of: weaving; preprocessing; presetting; dyeing; and after treatment. The invention has the advantages that since the hydrophilic fiber is used for the face structure and the hydrophobic fiber is used for the bottom structure, the one-way moisture guiding effect is excellent and durable, the material of the hydrophilic fiber and the hydrophobic fiber forming the face structure and the bottom structure is wide in source and low in price so as to be conductive to reducing the cost and lead the fabric to meet the popular consumption needs; the provided processing method does not need to put grey cloth into a cylinder in the pretreatment process like the existing technology; and the whole processing method is simple in the process steps, has no demanding requirement and can guarantee that the fabric has stable one-way moisture guiding property.

Description

technical field [0001] The invention belongs to the technical field of knitted fabrics, in particular to a one-way moisture-wicking knitted double-sided fabric, and also relates to a processing method thereof. Background technique [0002] Chinese Invention Patent Application Publication No. CN102134777A discloses a method for processing double-sided fabrics with one-way moisture guide and cool function, which uses the cool nylon fiber FLYCOOL (produced by China Taiwan Mingju Industrial Co., Ltd.) as the inner layer of the fabric and The bad fabric obtained by using ordinary fibers as the outer layer of the fabric is sequentially pretreated, dyed or whitened, softened and heat-set to obtain a one-way moisture-wicking knitted double-sided fabric. Although this patent application scheme can embody the technical effect described in column 0026 to column 0030 of its description to a certain extent, it also has the following shortcomings: First, since the gray cloth needs to be p...
