Problems solved by technology

Its disadvantage is that it is limited by the specifications of the fabric weave. It can only produce knitted fabrics of specific specifications. It is not suitable for most fabric products, and it cannot develop other fabric products with single-sided water and oil repellency.

Embodiment 1

[0041] Water and oil repellent finishing of pure cotton twill fabric on one side:

[0042]Generally, fabrics that require water- and oil-repellent finishing have better hydrophilicity, and the treated pure cotton fabrics have better hydrophilicity. The production process of this pure cotton single-sided water- and oil-repellent fabric is as follows: Pure cotton fabric→singeing→scouring→bleaching→(dyeing)→setting→pre-baking (heating the cloth surface to 80-130℃)→spraying water and oil repellent finishing agent on one side→infrared drying→baking→finished product.

[0043] 1) In the process flow, from pure cotton gray cloth → singeing → scouring → bleaching → (dyeing) → finalizing, this process is a conventional process for ordinary pure cotton fabrics, and the fabrics processed by this process can become finished products, also It can be used as a semi-finished product for subsequent processing. In this embodiment, it is used as a semi-finished product and continues to be treate...

Embodiment 2

[0050] One-sided water- and oil-repellent finishing of pure cotton twill fabric: the process before the one-side water- and oil-repellent finishing is the same as in Example 1, and the single-side water- and oil-repellent finishing process is as follows:

[0051] The thickness of the semi-finished product after setting is 0.25mm, and the fabric is pre-dried in a hot air oven to make the temperature reach 110°C. After that, a water-repellent and oil-repellent finishing agent is sprayed on one side of the fabric. Fluoropropyl ethylene acetate, its concentration is 200g / L, and the amount of liquid supplied to the surface of the fabric is 10%, calculated and controlled according to the flow rate of the metering pump and the cloth speed. Then in a hot air oven at 100°C for 70 seconds, the fabric is basically dry, and then baked at 170°C for 30 seconds to obtain the finished product.

[0052] The finished product is the process of inspection, rolling and packaging.

[0053] The wat...

Embodiment 3

[0055] One-sided water- and oil-repellent finishing of pure cotton twill fabric: the process before the one-side water- and oil-repellent finishing is the same as in Example 1, and the single-side water- and oil-repellent finishing process is as follows:

[0056] The thickness of the semi-finished product after setting is 0.6mm, and the fabric is pre-dried in a hot air oven to make the temperature reach 130°C. After that, a water-repellent and oil-repellent finishing agent is sprayed on one side of the fabric. The finishing agent is polyfive Fluoropropyl vinyl acetate, its concentration is 164g / L, and the amount of liquid supplied to the fabric surface is 30%, calculated and controlled according to the flow rate of the metering pump and the cloth speed. Then in the hot air oven, the temperature is 90°C and the drying time is 150s. The fabric is basically dried, and then baked at 140°C for 30s to obtain the finished product.

[0057] The finished product is the process of inspe...

Abstract

The invention provides a method for single-sided fabric finishing, which comprises the following steps: 1) pre-drying fabric; 2) applying finishing solution on a single side of the fabric by means of spraying; and 3) drying the fabric obtained in the second step, and obtaining the finished fabric product after drying. The method has a simple technical process, and can greatly improve the production efficiency in fabric finishing. After the single-sided finishing, such as the single-sided water-repellent and oil-repellent finishing, the fabric not only can meet the requirements for water repellence and oil repellence, but also can be worn more comfortably, thereby improving the product grade.

Description

technical field [0001] The invention relates to a fabric finishing method, more specifically, to a fabric one-side finishing treatment method, which can endow the fabric with different properties on both sides. Background technique [0002] For the finishing of fabrics, the traditional method is dipping or padding, followed by drying and baking. The finishing liquid in these two finishing methods is completely evenly distributed in the fabric, and the amount of liquid supplied to the fabric reaches 50% to 100%, or even higher. , After finishing, the effect on both sides of the fabric is the same, whether it is dipping or rolling, it belongs to the finishing of the whole fabric. And the finishing of fabrics is varied, such as water-repellent and oil-repellent finishing, antibacterial finishing, resin finishing, anti-ultraviolet finishing, softening finishing, etc. The traditional method is to carry out these finishings on fabrics on both sides. [0003] Some finishes are act...
