Abstract

The invention relates to a method for silkening a film, pertaining to the technical field of weaving. A film cutting drafting device is arranged behind each drafting system of a spinning machine. A cutting region is formed between a cutting-endurable ring and a cutting roller of a film placing and cutting device. Film material enters the cutting region through an unwinding roller and cut to form stripped-shaped multifilaments. A conventional linear discharge and filamentation method for spinneret holes is changed. After multifilaments are outputted through the cutting region, the multifilaments enter a first drafting region and is pulled and outputted through a strand drafting jaw. The multifilaments enter a second drafting region for secondary hot drafting. Each strand of the multifilaments becomes slimmer and higher in strength. Electrostatic spinning centrifuge spinning and conventional nano-spinning methods are avoided. Production and manufacture of nano strands are quickly achieved. The method for silkening the film has the following beneficial effects: a film material silkening mode with high efficiency and short process is developed; a film industry and a weaving industry are effectively merged; the range and fields of textile raw materials are expanded; and the method for silkening the film is convenient to operate and easy to promote and apply.

Description

technical field [0001] The invention relates to a method for forming filaments from molded films, which belongs to the technical field of textiles. Background technique [0002] Textile fibers can be divided into natural fibers and chemical fibers according to their sources; chemical fibers generally include recycled fibers and synthetic fibers. Among them, man-made fibers refer to natural polymers that originally existed in nature. Because the length and thickness of the macro-aggregated form cannot meet the requirements of textile processing, it needs to be re-assembled by chemical methods to form fibers to meet the requirements of textile processing. Such as regenerated cellulose fibers, various viscose fibers, etc.; synthetic fibers refer to petrochemical small molecules as raw materials, chemically synthesized polymers, and then processed into chemical filaments through spinning processes. The production of chemical filaments can be divided into melt spinning and solut...
