Description

Technical Field

[0001] The invention relates to the technical field of drying, and in particular to a low-energy consumption fabric drying process. Background Art

[0002] The drying industry refers to the production activities of drying various raw materials and products using professional drying equipment. With the development of industry and the improvement of people's requirements for product quality, the drying industry has been widely used in various fields, especially in the textile industry, where the drying process is crucial to improving product quality and production efficiency.

[0003] Silk fabrics are mainly composed of silk fibers, which are natural fibers that give silk a unique texture and luster. High-end silk fabrics have strict requirements in terms of fiber composition, yarn density, color difference, strength, feel, etc. The comfort of silk is its main use characteristic, so it is very important to maintain its original softness and luster during the drying process.

[0004] Traditional silk drying technology mainly relies on sun drying or steam drying. Although sun drying is environmentally friendly, it is limited by weather conditions and the drying is uneven. Although steam drying can achieve rapid drying, it has problems such as high energy consumption, uneven heating, and environmental pollution. Based on this, the present invention provides a low-energy consumption fabric drying process. Summary of the invention

[0005] The purpose of the present invention is to provide a low-energy consumption fabric drying process, which can reduce energy consumption while maintaining the original softness and glossiness of the fabric after drying.

[0006] In one aspect, the present invention provides a low energy consumption fabric drying process, comprising the steps of: (1) Pretreatment: dust removal and washing pretreatment of fabrics; (2) Fabric preparation and layout: Adjust the fabric layout according to the thickness of the fabric. When the fabric is thin, lay it flat in a single layer; when the fabric is thick, lay it in multiple layers in an alternating pattern. (3) Preliminary drying: Preliminary drying is carried out at a temperature of 30°C-35°C, and the drying time is 14-18 hours; (4) Deep drying and shaping: Raise the temperature to 38-42°C at a rate of 0.5-1°C / min and continue drying for 8-12 hours; (5) High temperature drying: Raise the temperature to 45℃-50℃ and perform high temperature drying for 4-6h; (6) Cooling and shaping and post-processing: Natural cooling at room temperature or using cold air to shape, remove excess threads and trim the edges.

[0007] Furthermore, the dust removal in step (1) is to remove dust and impurities on the surface of the fabric by a whisk method.

[0008] Furthermore, in step (1), the washing is performed by rinsing with deionized water, and after rinsing, excess water is gently absorbed by a clean absorbent, and finally the pretreated fabric is naturally dried until no obvious water droplets are left.

[0009] Furthermore, in step (2), the multiple layers are staggered and each layer is separated by a soft non-woven fabric or a drying pad.

[0010] Furthermore, during the deep drying process in step (4), the air humidity is controlled at 10-12%.

[0011] Furthermore, during the high temperature drying process in step (5), the air humidity is controlled at 6-8%.

[0012] Furthermore, the high temperature drying method in step (5) is one of drum drying, hot air drying and far infrared drying.

[0013] Furthermore, the high temperature drying method in step (5) is far infrared drying.

[0014] Furthermore, the fabric is silk.

[0015] The beneficial effects of the present invention are: The present invention accurately controls temperature and humidity during the drying process. Low-temperature drying avoids damage to fabric fibers caused by high temperature and maintains the softness of the fabric. Humidity control ensures that the fabric will not be deformed or damaged due to over-drying during the drying process.

[0016] The present invention adopts a gradual temperature increase strategy to gradually adapt the fabric to a higher temperature, thereby avoiding the influence of sudden temperature changes on the fabric and ensuring the stability and efficiency of the drying process.

[0017] The natural cooling or cold air setting of the invention can fix the fabric fibers naturally without being disturbed by external forces, thereby improving the stiffness and glossiness of the fabric.

[0018] The low-energy fabric drying process of the present invention achieves the goal of maintaining the original softness and glossiness of the fabric while reducing energy consumption through meticulous pretreatment, reasonable fabric layout, precise temperature and humidity control, gradual heating strategy, and natural cooling and shaping.
