Description
Technical Field
The invention relates to the technical field of textiles, in particular to a finishing method of a waterproof and moisture permeable garment fabric.
Background
With the rapid development of functional textiles, the traditional means of simply relying on functional fibers to improve the functions of textiles is increasingly limited. Although functional fibers of various materials are continuously developed, it is still difficult to satisfy the functional requirements of functional textiles. The functionality of the textile fabric is increased by applying a high-tech after-finishing technology to protect the textile fabric from various adverse environments, and the obtained after-finishing coating is a better way for quickly obtaining various functional textile fabrics. Functional textiles can be designed for various purposes by means of after-treatment treatments, such as ultraviolet radiation, bad weather, microorganisms or bacteria, high temperatures, chemicals such as acids, alkalis, and mechanical abrasion, etc. Consequently, textile finishing techniques are receiving increasing attention.
Among functional textiles, the waterproof and moisture permeable fabric is a fabric with great development potential in garment fabrics. The waterproof moisture-permeable fabric means that water does not soak into the fabric under certain pressure, and sweat emitted by a human body can be conducted to the outside through the fabric in a water vapor mode, so that the sweat is prevented from accumulating and condensing between the body surface and the fabric, and the comfort of the garment is kept. The waterproof moisture permeable fabric is a functional fabric with high technology and unique characteristics. The waterproof moisture-permeable fabric is often used as fabrics of outdoor sportswear, trousers, cold protective clothing and the like, and particularly in recent years, the demand of the waterproof moisture-permeable fabric in sportswear is increased rapidly.
At present, relatively mature waterproof and moisture permeable fabric treatment technologies exist, and the common technologies include: the fabric is compacted and is adhered with the film type waterproof fabric and the coating type waterproof fabric. The fabric densification is mainly realized by compacting fiber yarns, so that the fabric is too compact, the cost of the textile is high, and the flexibility is poor; the adhesive film type fabric has excellent performance, good waterproof effect and high adhesion fastness, but the stretching pore-forming process of the microporous membrane is complex and has high requirements on the material; the coated fabric is a waterproof moisture-permeable coating obtained through later-stage finishing, the fabric can be easily processed in a large scale in batches, and the technology is highly concerned and popularized by the textile industry. The technology for preparing the waterproof and moisture permeable textile by utilizing the post-finishing coating is still restricted by the technology, and the key for obtaining the waterproof and moisture permeable textile by the coating fabric at present is how to keep washing resistance and have good waterproofness and moisture permeability.
The Chinese invention patent application No. 201010245809.2 discloses a high-water-pressure-resistant high-moisture-permeability coating fabric, which comprises a force-bearing layer, a waterproof layer coated on the force-bearing layer, a microporous layer coated on the waterproof layer, and a protective layer coated on the microporous layer, wherein the protective layer is a wear-resistant coating with a microporous structure; the protective layer is a hydrophilic waterproof moisture-permeable polyurethane coating with hydrophilic performance, the middle microporous layer is a microporous waterproof moisture-permeable polyurethane coating with a microporous structure, the bottom layer of the fabric coating is a waterproof layer, and the layer is a hydrophilic waterproof moisture-permeable polyurethane coating with better film forming performance and higher water pressure resistance. The Chinese patent application No. 201210066104.3 discloses a method for preparing a waterproof moisture-permeable coated fabric. The method comprises the following steps: (1) water repellent finishing before fabric: performing one-dipping one-rolling water repellent treatment on the fabric by adopting a fluorine water repellent finishing agent, then pre-baking for 1-3min at the temperature of 80-100 ℃, and then baking for 60-90s at the temperature of 140-180 ℃; (2) coating finishing: the coating agent comprises the following components in parts by weight: 100 parts of water-based coating agent, 2-6 parts of surfactant and 15-25 parts of cellulose ether or derivatives thereof diluted by 1:20 with water; (3) pre-baking at 80-100 deg.C for 1-3min, and baking at 120-160 deg.C for 60-90 s.
In order to effectively solve the problems that the coating of the coating type waterproof moisture permeable fabric obtained by using the coating finishing technology is easy to elute and continuous uniform moisture permeable micropores are difficult to obtain, a novel finishing method of the coating type waterproof moisture permeable fabric is needed, and then the textile fabric with good waterproof moisture permeable performance is obtained.

It is well known that to achieve water and moisture permeability in textiles, textile coatings or materials are required to be hydrophobic or have micropores that block water transmission. Generally, the fabric with certain hydrophobicity is not completely dispersed when water splashes on the fabric, but is in the form of tiny droplets, and the size of the droplets can reach 50-300 μm, so that when the coating of the fabric is provided with micropores smaller than 10 μm, the fabric can be waterproof, and the micropores smaller than 10 μm can completely meet the moisture permeability requirement. The existing technology for preparing waterproof and moisture permeable textile fabrics by utilizing after-finishing coatings is restricted by technology and mainly shows that the drapability and the flexibility of the fabrics after the coatings are treated are poor; the waterproof coating is easy to damage in washing, and has poor durability and poor adhesion fastness; more importantly, the coating can keep continuous and uniform moisture permeable micropores while forming water resistance, and the process difficulty is higher. Therefore, the waterproof and moisture permeable properties of the current textile are mainly direct coating, on one hand, the coating is easy to elute, and on the other hand, continuous and uniform moisture permeable micropores are difficult to obtain on the other hand.

Further, a foaming agent, a three-proofing finishing agent and an acrylate emulsion are uniformly dispersed to obtain a finishing liquid, the finishing liquid is sprayed on the surface of the pre-finished textile fabric through ultrasonic atomization spraying, the ultrasonic atomization spraying is realized by spraying low-pressure air from a small hole in the center of a nozzle under the action of ultrasonic waves with a certain frequency, the finishing liquid is sprayed to the surface of the nozzle through an external guide pipe to generate fine liquid particles and generate high oscillation, so that superfine liquid drops can be generated, the acrylate emulsion in the finishing liquid has good adhesion to the textile fabric, so that the textile fabric is preheated while the fine liquid drops of the finishing liquid form a film on the surface of the textile fabric, gas generated by the contained foaming agent forms continuous fine micropores, and when the finishing liquid is thermally cured to form a coating, the foaming agent releases gas to form micropores on a soil layer, the coating layer is endowed with good micropores, and is favorable for moisture permeability, and the three-proofing, finally, the textile fabric with excellent waterproof and moisture-permeable performances is obtained.
The existing coating finished textile fabric for improving the waterproof moisture permeability of the textile fabric has the problems that the coating is easy to elute and the continuous uniform moisture permeability micropores are difficult to obtain, so that the application of the coating is limited. In view of the above, the invention provides a finishing method of waterproof and moisture permeable garment materials, which comprises the steps of adding silk fibroin powder into water, dispersing and stirring, introducing nitrogen, gradually heating, adding an initiator, stirring, gradually adding acrylic acid into the mixture, stirring at a low speed, reacting to ensure that acrylic acid is grafted and modified with the silk fibroin powder to obtain a grafted and modified silk fibroin dispersion solution, and then adding chitosan, calcium chloride and deionized water, and uniformly dispersing to form slurry; soaking the textile fabric in water glass solution, and rolling to remove excessive water glass solution; soaking the pretreated textile fabric into pulp for two times, and then pre-drying the textile fabric after the two soaking for two times to obtain a pre-finished textile fabric; uniformly dispersing a foaming agent, a three-proofing finishing agent and an acrylate emulsion to obtain a finishing liquid, thermally drying a pre-finished fabric by using a roller, conveying the pre-finished fabric into a spraying chamber, spraying the finishing liquid on the surface of the fabric by using ultrasonic atomization spraying in the spraying chamber, releasing gas by using the foaming agent to form micropores in a soil layer when the finishing liquid is thermally cured to form a coating, and drying, cleaning and drying by using the roller to obtain the waterproof and moisture permeable clothing textile fabric.

The test method comprises the following steps:
testing waterproof moisture permeability: the substrate fabric is a polyester fiber fabric; washing the fabric according to a household washing and drying program for textile test (GB/T8629-2017), and washing the fabric by using a standard detergent 1 according to a 4H washing program by using an A-type washing machine; and the drying adopts natural airing for 48 hours. The fabrics finished by the methods of the examples and comparative examples were subjected to the following tests before and after washing, respectively:
(1) and (3) testing the waterproof performance:
and judging the waterproofness by using the hydrostatic pressure grade, and referring to a hydrostatic pressure test for measuring the water impermeability of textile fabrics (GB/T4744-2013), increasing the hydrostatic pressure at the speed of 6.0kP/min until the hydrostatic pressure of water drops is taken as the hydrostatic pressure value, and testing the hydrostatic pressure and the grade before and after washing. The test results are shown in table 1.
Moisture permeability test:
reference standard "textile fabric moisture permeability test method section 2: the evaporation method (GB/T12704.2-2009) measures the moisture permeability at 20 ℃ and 65% relative humidity in a positive moisture permeable cup, and measures the moisture permeability before and after washing.
