Abstract

A spinning system and method for sheet-shaped materials. The spinning system comprises sheet-shaped materials, which are not limited to a base material and woven products and which serve as raw materials, wherein a cutter of a strip-forming device moves in a set direction to cut various sheet-shaped materials so as to obtain strip-shaped materials; pre-treatment and after-finishing are performed so as to make the strip-shaped materials suitable for spinning; and a yarn-forming device is used to twist at least one strip-shaped material into textile yarn. By using sheet-shaped materials, the present disclosure has the advantages of a relatively short industry chain, low cost, low requirements for fibers, and a wide variety of web-forming crafts; a conventional non-woven fabric chain is combined with a spinning chain, effectively reducing the weaving costs of non-high-yarn-count yarn, and therefore the present disclosure can be used for secondary yarn-forming utilization of coarse fibers, short fibers, hard fibers, etc. in textile waste; the parameter requirements of raw fibers required for conventional spinning can be greatly reduced, facilitating the use of new natural materials in forming yarn; and fibers which have been subjected to web formation can meet the requirement for required mechanical stretching, thus expanding the range of raw materials for spinning.

Abstract

A composite yarn, which comprises a core yarn and a covering yarn, wherein the covering yarn winds around and covers the outer side of the core yarn to form an exposed-core-type structure, and the moisture regain of the core yarn is different from that of the covering yarn. The present invention further relates to a method for preparing the composite yarn and the use of the composite yarn. The swelling of the composite yarn is controllable, and since the outer-layer covering yarn does not fully wind around and cover the inner-layer core yarn, multiple capillary channels and alternating humidity gradients are constructed on the outer circumferential face of the yarn, thereby improving the effects of moisture absorption and moisture transferring of the yarn. The method for preparing the composite yarn is easy and simple to operate, easy to implement, and is suitable for large-scale industrial application.

Abstract

In a hydrothermal reaction system(200) for processing raw materials, such as organic waste, clothing, fabrics, etc., with a superheated reaction solution, two or more hydrothermal reactors(211a-c) are used. Each reactor(211a-c) may be a subcritical water reactor(211a-c). The reaction solution recovered after reacting with a first batch of raw materials deposited in a first reactor(211a-c) is transferred to a second reactor(211a-c) for recycling the reaction solution in reacting with a second batch of raw materials. Discharging the reaction solution after processing one batch is eliminated, and cooling of the reaction solution is not required. Furthermore, while reaction in the first reactor(211a-c) is in progress, the second batch of raw materials is conveniently deposited into the second reactor(211a-c) under atmospheric pressure. The system(200) operates in a semi-continuous manner as a new batch of raw materials is processed shortly after one batch is completed in processing. Stable reaction is thus achievable.

Abstract

For recycling, fibers are recovered from fibrous products by using two or more hydrothermal reactors to conduct hydrolysis. The fibrous products are divided into batches. A batch to be hydrolyzed is fed to a selected reactor under atmospheric pressure. A superheated reaction solution containing subcritical water and one or more organic acids is transferred alternately and/or successively among the reactors to hydrolyze respective batches in the reactors. By using two or more reactors to carry out the heat treatment, it is possible to reuse the organic acid-containing reaction solution without discarding. Since the reaction solution, maintained at a high temperature, can be recycled without discarding and cooling, high material-utilization efficiency and high energy efficiency is achievable. Furthermore, a system for recovering the fibers is realizable compactly to occupy a small space since the cooling equipment is not required and only two reactors need to be installed.

Abstract

A garment-to-garment system for manufacturing new garments via recycling abandoned garments avoids, or minimizes the likelihood of, generating wastewater by the following approach. The abandoned garments are waterlessly sanitized by ozone fumigation. Fabric pieces of the sanitized abandoned garments are opened with dust removal to form fiber tufts, which are subsequently divided with trash removal to form fiber clumps. The fiber clumps are waterlessly sanitized by ozone fumigation or UV-C irradiation. Advantageously, the fiber clumps are spread out to form a web of fibers during sanitization. The exposed surface area of the fiber web is significantly higher than that of the abandoned garments, thereby increasing the sanitization effectiveness. The new garments are then formed from the sanitized fiber clumps by standard garment-manufacturing processes.

Abstract

A multispectral imaging color measurement system, comprising a dark room (6), a sample platform and an imaging system (1) for photographing objects to be measured; also comprising a controllable illumination system, a filter wheel system, an imaging signal processing system and an electronic control system. The controllable illumination system provides a high spatially-homogeneous illuminated environment for the imaging system (1). The filter wheel system filters the reflected light emitted by the controllable illumination system and reflected by the sample to be measured, and provides a light band with a proper wave length for the imaging system (1) to image. The imaging signal processing system calibrates and performs reflective reconstruction for the image taken by the imaging system (1). The electronic control system controls the operation of each part of the multispectral imaging color measurement system. A method for processing imaging signals of the multispectral imaging color measurement is also proposed. The multispectral imaging color measurement system and the method for processing imaging signals thereof can overcome the defect of inaccuracy of traditional chroma imaging systems and spectrophotometer systems, and provide users in the textile industry with the basic functions of highly accurate color measurement and evaluation.
