A non-woven fabric entangling and functional finishing method based on step-by-step carbon dioxide fluid comprises the following steps: inputting a dry fiber web into a pretreatment cabin, injecting gaseous carbon dioxide into the pretreatment cabin to convert the gaseous carbon dioxide into supercritical carbon dioxide, dipping the fiber web into the supercritical carbon dioxide, injecting functional liquid, dipping the fiber web to obtain a finished fiber web, and drying the finished fiber web to obtain the non-woven fabric entangling and functional finishing method based on the step-by-step carbon dioxide fluid. Then separating the finished fiber web from supercritical carbon dioxide under an anti-precipitation pressure, jetting a fluid formed by subcritical carbon dioxide to the finished fiber web, enabling the fluid jet to penetrate through or penetrate into the fiber web to entangle raw material fibers in the fiber web until an entangled fiber web is obtained, and then performing pressure relief on an environment in which the entangled fiber web is located to obtain the finished fiber web. And vaporizing the carbon dioxide fluid to generate gaseous carbon dioxide. By means of the design, functional finishing and entanglement reinforcing can be coordinated, the strong entanglement reinforcing and functional finishing effects are achieved, water consumption and energy consumption are reduced, and adjustability is high.

The present application relates to the technical field of textiles, in particular to a high-elasticity polyester-cotton blended woven sports fabric and a preparation method thereof, aiming to solve the bottleneck of material incompatibility, process conflict and performance difficulty in balancing when integrating high elasticity, cotton-like comfort and intelligent response functions in the existing sports fabric. The fabric is woven from a variety of plasma-grafted functional fibers, and through the innovative application of supercritical CO2 fluid treatment and microwave catalytic fixation process, the damage of traditional high temperature and high pressure conditions to fiber materials and functional molecules is avoided, and at the same time, the firm combination between the functional layer and the fiber substrate is ensured. Through systematic design of fiber components, fabric structure and functional finishing process, the problems of insufficient multifunctional integration, mutual performance restriction and insufficient mechanical properties in the prior art are solved, and a new solution is provided for high-strength sports and daily leisure scenarios.

The invention relates to a method, a product and a system for cleaning and recycling waste textiles by using carbon dioxide fluid, which comprises the following steps of: putting an obtained waste fiber net into a pretreatment tank, injecting supercritical carbon dioxide into the pretreatment tank to statically soak the waste fiber net to obtain a soaked fiber net, taking the soaked fiber net out of the pretreatment tank, and drying the soaked fiber net in a drying oven to obtain a finished product. The method comprises the following steps of: soaking a fiber web in the fiber web, feeding the fiber web into an entangling working chamber, ejecting a fluid jet flow formed by supercritical carbon dioxide or subcritical carbon dioxide from top to bottom to the soaked fiber web, penetrating or penetrating the fluid jet flow into the fiber web to entangle fibers in the fiber web, and washing pollutants on the fibers until the fiber web is conveyed out of the entangling working chamber; therefore, the reinforced fiber web is obtained. According to the design, mutual cooperation of cleaning and entanglement can be achieved, the recycling effect is good, water consumption and energy consumption are low, and environment friendliness is achieved.
