Problems solved by technology

The second is that a large number of used clothes are mostly buried or burned as garbage, which not only causes a waste of resources, but also pollutes the environment
Although this is a more feasible method, the fibers prepared by it can only be used in ordinary products and cannot be used efficiently

Embodiment 1

[0023] A new high-efficiency, energy-saving and green process for preparing differentiated fibers based on waste and old clothing, the process steps are as follows,

[0024] 1) First classify the recovered waste clothes, remove large debris, and then cut off buttons, zippers, etc., and then soak the waste clothes in the soaking solution with bactericidal effect for 3-6 hours, and keep stirring, Remove sundries, oil stains, etc. on waste clothes, remove and drain the water for later use;

[0025] 2) Break the clothes drained in step 1) into pieces or strips of rags, with an area of ​​0.5-5cm 2 It is advisable to send the rags into the drying equipment and bake them at a low temperature of 40-70°C for 2-3 hours, which can increase the activity of the fibers in the rags, facilitate subsequent processing, and also play a bactericidal role ;

[0026] 3) Take out the rags baked in step 2) and cool them down to room temperature, then send them to the low-temperature freezer to free...

Abstract

The invention provides a novel process for efficient, energy-saving and green preparation of distinctive fibers by waste old clothes. The novel process comprises the following steps: classifying the waste clothes; cutting off buttons and zippers and putting the waste clothes into an impregnation solution; impregnating for 3-6 hours; fishing out the clothes and draining for later use; crushing the drained clothes into block-shaped or strip-shaped crushed cloth; conveying the crushed cloth into drying equipment and braking at a low temperature for 2-3 hours; taking out the baked crushed cloth and cooling to a room temperature; conveying the crushed cloth into low-temperature freezing equipment and freezing for 2-3 times, wherein the freezing time of each time is 1-3 hours and the freezing temperature ranges from -5 DEG C to 0 DEG C; putting the frozen crushed cloth into a self-made solution and impregnating for 12-24 hours; fishing out and draining; airing under a natural environment; crushing the treated crushed cloth to form bubble-buddle materials; conveying the bubble-buddle materials into a smelting furnace to be smelted to obtain granulated semi-finished-product raw materials; conveying the granulated semi-finished-product raw materials into a granulating machine to be granulated to obtain grain-shaped fiber materials; and smelting the grain-shaped fiber materials into a macromolecular solution according to preparation requirements of a down-stream product, and drawing to obtain the distinctive fibers.

Description

technical field [0001] The invention relates to the technical field of resource reuse, in particular to a new process for preparing differential fibers with high efficiency, energy saving and greenness based on waste clothes. Background technique [0002] The scarcity and pollution of resources are common problems faced by the world today. The textile industry is closely related to people's lives, and the world's textile industry is also facing two major problems: First, with the development of the world economy and technology, the application field of textiles is gradually expanding, but its service life is shortened. With the rapid growth, the consumption of textiles has increased greatly, resulting in a shortage of textile raw materials and a sharp rise in prices. The second is that a large number of used old clothes are mostly buried or burned as garbage, which not only causes a waste of resources, but also pollutes the environment. The completion of a piece of clothin...
