The method of making microfilament fibrous into silk-like cotton through air-lay

Abstract

The method of making microfilament fibrous into silk-like cotton through air-lay is related to the silk-like cotton technique field. It includes the microfilament fiber whose average fiber degree is less than or equal to 0.3 dtex and the water insoluble thermoplastic resin that is not more than 5% relative to the part by weight of the adhesive-bonded fabric. The vertical and horizontal tensile strength of the silk-like cotton: fabric weight of the silk-like cotton is more than or equal to 0.4. Using the air pressure lapper can blow the airstream into the polyester staple fiber whose fiber length is measured from 10mm to 50mm (leftover pieces for cutting down and the 'waste cotton' dropped from the machine) and microfilament to form a fiber mesh. The technique can avoid fiber fires coming off. A certain proportion of low-melting fiber is added when the hopper is fed. Surface pressing is being carried out through blanching roller after baking oven shaping. Batting surface is skinned because of the high temperature of blanching roller, not only attractive in appearance but also uniform. It can make surface smooth and reduce fiber fines coming off. Our company carries out the combination of both technology to fully use the 'waste cotton' in the production process, reducing environmental pollution so that resource efficiency can be configured.

Description

Technical field [0001] The invention relates to the technical field of silk-like cotton, in particular to a method for preparing superfine filament fiber air-laid silk-like cotton. Background technique [0002] The traditional production process of silk-like cotton is feeding machine → pre-carding → opening machine → carding machine → netting machine → oven → forming → cooling → rolling → packaging → storage. The carding of silk-like cotton produced by traditional technology is to make the fibers interconnected and entangled through carding. There are certain requirements on the length of the fibers, so that the fibers can be interconnected and entangled to form a net. For companies that mass produce imitation silk cotton, spray cotton, and imitation silk cotton, a lot of "waste cotton" will fall from the machine, as well as trimmings. Because these "waste cotton" fibers are short in length, they cannot It is once again carded into a web with a traditional carding machine, so it...

AI Technical Summary

Problems solved by technology

For companies that produce imitation silk cotton, glued cotton, and silk imitation cotton in large quantities, there will be a lot of "waste cotton" on the machine, as well as trimmed scraps. Due to the short length of these "waste cotton" fibers, they cannot It is combed into a web again with a traditional carding machine, so it cannot be recycled. Enterprises need to spend a certain amount of energy to deal with these "waste cotton" and transport it to the garbage dump or incinerate it, which will cause environmental pollution and waste of resources.
