Embodiment 1

[0025] The woven fabric base fabric made of polyester fiber and its blended fibers is used as the raw material. The gram weight of the woven fabric base fabric is 60g / m2. The fibers on one side of the fabric have better water absorption effect. Viscose fiber or polyester fiber is added to the ester fiber, and the special-shaped section is used. After pre-treatment, dyeing and water absorption in the same bath, single-sided water-repellent processing and post-finishing, a fabric No. 1 is obtained. It has a water-absorbing layer and a water-repellent layer. Fibers with better water absorption are used, and the water-repellent layer is treated with water-repellent treatment.

[0026] The single-sided water-repellent processing and the post-finishing integrated processing include one dip, one rolling, drying, and baking. 160~180℃, the time is 120S, the proportion of each component of the water-repellent finishing agent used in single-sided water-repellent processing is: silicon-ba...

Embodiment 2

[0029] The non-woven fabric base fabric made of polyester fiber and its blended fibers is used as the raw material. The weight of the woven fabric base fabric is 80g / m2. Fabric No. 2 is obtained by integrated processing, which has a water-absorbing layer and a water-repellent layer, the water-absorbing layer is made of fibers with better water-absorbing effect, and the water-repellent layer is treated with water-repellent treatment.

[0030] The single-sided water-repellent processing and the post-finishing integrated processing include one dip, one rolling, drying, and baking. 150~170℃, the time is 80S, the proportion of each component of the water-repellent finishing agent used in single-sided water-repellent processing is: non-fluorine water-repellent agent 55g / l, cross-linking agent 10g / l, antistatic agent 10g / l l, citric acid 0.6g / l.

[0031] When absorbing water in the same bath for dyeing, the temperature is controlled at 50-80°C, and the treatment time is 10min.

Embodiment 3

[0033] The woven fabric base fabric made of polyester fiber and its blended fibers is used as the raw material. The weight of the woven fabric base fabric is 100g / m2. The fibers on one side of the fabric have better water absorption effect. Viscose fiber or polyester fiber is added to the ester fiber, and the special-shaped section is used. After pre-treatment, dyeing and water absorption in the same bath, single-sided water-repellent processing and post-finishing, the fabric No. 3 is obtained. It has a water-absorbing layer, a water-repellent layer, and a water-absorbing layer. Fibers with better water absorption are used, and the water-repellent layer is treated with water-repellent treatment.

[0034] The single-sided water-repellent processing and the post-finishing integrated processing include one dip, one rolling, drying, and baking. 150~180℃, the time is 50S, the proportion of each component of the water-repellent finishing agent used in single-sided water-repellent pr...

Abstract

The invention belongs to the field of textiles and garments, and discloses a single-side water-repellent and single-side water-absorbent fabric and its processing technology, including a water-absorbing layer and a water-repellent layer. Finished and processed in one. The beneficial effects of this patent are: the water repellency of the fabric obtained by the process of the present invention reaches above level 4 before washing, and still reaches above level 3 after washing 10 times, and the water absorption performance of one side is all above 3 before washing and after washing 10 times. Within seconds, it can quickly absorb splashed blood without penetrating into the user's inner clothing, which can be widely used in products such as medical surgical gowns.

Description

technical field [0001] The invention relates to the field of textiles and clothing, in particular to a single-sided water-repellent and single-sided absorbent fabric and a processing technology thereof. Background technique [0002] In recent years, with the continuous improvement of living standards, people's requirements for clothing are more and more expected to take into account the comfort, practicality and aesthetics of wearing, which requires the fabric to have the effect of breathability, water repellency on one side and water absorption on one side. The existing process is realized by laminating two kinds of fabrics or filming, which brings the disadvantages of long production cycle, high energy consumption, high processing cost and low air permeability. The fabric weight can only be used in autumn and winter clothing fabrics. [0003] For example, the announcement number is CN2629475Y for medical protective clothing made of multifunctional fabrics with good breatha...
