Problems solved by technology

In this method, the inner hydrophobic yarn is treated with the hydrophobic treatment of the bobbin yarn. It is difficult to ensure the uniform water repellency effect of the inner and outer yarns of the bobbin, and the dyeing and finishing of the fabric are prone to color patterns, which will affect the quality of the final fabric and the one-way moisture transfer effect. The comfort and breathability of the inner fabric is not good

Embodiment 1

[0042] This application discloses a unidirectional moisture-guiding base dyed fabric, the inner layer of which is 100% water-repellent cotton gray yarn. Water-repellent cotton gray yarn is made by mixing water-repellent cotton fiber and ordinary cotton fiber according to the requirements of blended yarn, and then through carding, drawing, roving, spun yarn, winding and other processes. The amount of water-repellent cotton used is 20 wt%.

[0043] Wherein the preparation technology of water-repellent cotton fiber is:

[0044] Refining: the mass ratio of cotton fiber to water is 1:10, the osmotic refining agent containing 1.5g / L and the sodium hydroxide of 4g / L are contained in the described pretreatment aqueous solution, scoured at 98 ℃ for 55 minutes; It is a mixture of fatty acid methyl ester polyoxyethylene ether and sodium dodecylsulfonate at a mass ratio of 1:1;

[0045] Hot wash: hot wash at 85°C for 20 minutes;

[0046] Peracid treatment: the peracid refers to the imp...

Embodiment 2

[0071] This embodiment discloses a one-way moisture-guiding base dyed fabric, the inner layer of which is 100% water-repellent cotton gray yarn. Water-repellent cotton gray yarn is made by mixing water-repellent cotton fiber and ordinary cotton fiber according to the requirements of blended yarn, and then through carding, drawing, roving, spun yarn, winding and other processes. The amount of water-repellent cotton added is 50wt%.

[0072] Wherein, the preparation technology of water-repellent cotton fiber is:

[0073] Refining: the mass ratio of cotton fiber to water is 1:10; the pretreatment aqueous solution contains 1.5g / L osmotic refining agent and 4g / L sodium hydroxide, and is scoured at 98°C for 55 minutes; the refining agent It is a mixture of fatty acid methyl ester polyoxyethylene ether and sodium dodecylsulfonate at a mass ratio of 1:2;

[0074] Hot wash: hot wash at 85°C for 20 minutes;

[0075] Peracid treatment: the peracid refers to the impregnation treatment w...

Abstract

The invention provides a one-way moisture-conducting blank-dyed fabric. The one-way moisture-conducting blank-dyed fabric is of a double-layer structure; an inner layer and an outer layer have the difference of hydrophilicity and hydrophobicity; the outer layer is a hydrophilic layer formed by hydrophilic yarn; the inner layer is a moisture conducting layer formed by hydrophobic yarn; and the outer layer and the inner layer are connected through fabric weave points. The one-way moisture-conducting blank-dyed fabric is obvious in moisture-absorbing and sweat-releasing effects, soft and comfortable in hand feeling and skin-friendly and breathable to wear, still has relatively good one-way moisture-conducting performance after being washed for multiple times, and meets the moisture-absorbing and sweat-releasing requirements of a dynamic moisture transfer method in a second part of GB / T21655.2-2019 evaluation of moisture absorption and quick drying of textiles.

Description

technical field [0001] The invention relates to the field of textiles, in particular to a unidirectional moisture-guiding blank dyed fabric. Background technique [0002] As a natural fiber, cotton fiber has been developed by humans as early as ancient times. It is very popular because of its good wearing comfort, environmental protection and biodegradability. However, cotton fibers will swell due to good hygroscopicity, slow down the evaporation rate of sweat, and affect the comfort of wearing. [0003] In order to achieve unidirectional moisture transfer performance, the fabric is usually finished after finishing, mainly water repellent additive treatment, waxing treatment or 3D printing treatment. This method is generally in the finishing stage, and the moisture transfer performance of this method is limited. Fabric The hand feeling is hard and the air permeability is not good; the publication number is CN104074061A, which discloses a single-sided waterproof and stain-re...
