Embodiment 1

[0038] Such as figure 1 As shown, this embodiment provides a production process for using waste textiles to manufacture flame-retardant canvas bags, including the following steps:

[0039] Pre-treatment of waste textiles: After cleaning and drying the collected waste textiles, the continuous cutting, crushing and magnetic separation processes are carried out through the integrated equipment of cutting, crushing and magnetic separation to obtain short filaments of textile fibers; The silk is impregnated with cleaning liquid, filtered, and dried to obtain separated fiber short filaments; wherein, the cleaning liquid is prepared by mixing the following raw materials in parts by weight: 8-15 parts of hydroxyethyl cellulose, 5-10 parts of fatty alcohol polyoxyethylene ether , 3-8 parts of sodium bicarbonate, 2-6 parts of lauric acid diethanolamide, 8-15 parts of citric acid, and 25-40 parts of ethanol; the waste textiles are selected from the waste textiles of polyester fiber fabri...

Embodiment 2

[0047] The difference between this example and Example 1 is that the cleaning solution is prepared by mixing the following raw materials in parts by weight: 14 parts of hydroxyethyl cellulose, 9 parts of fatty alcohol polyoxyethylene ether, 6 parts of sodium bicarbonate, dilauric acid 5 parts of ethanolamide, 12 parts of citric acid, 35 parts of ethanol.

[0048] The flame retardant is prepared from the following raw materials in parts by weight: 5 parts of melamine cyanurate, 3 parts of antimony trioxide, 11 parts of fatty alcohol polyoxyethylene ether, 4 parts of pentaerythritol, and 22 parts of ethanol.

[0049] The impregnation solution is prepared from the following raw materials in parts by weight: 9 parts of fatty alcohol polyoxyethylene ether, 5 parts of epoxy resin, 3 parts of melamine cyanurate, and 252 parts of soft water.

Embodiment 3

[0051] The difference between this example and Example 1 is that the cleaning solution is prepared by mixing the following raw materials in parts by weight: 13 parts of hydroxyethyl cellulose, 8 parts of fatty alcohol polyoxyethylene ether, 6 parts of sodium bicarbonate, dilauric acid 5 parts of ethanolamide, 13 parts of citric acid, 35 parts of ethanol.

[0052] The flame retardant is prepared from the following raw materials in parts by weight: 5 parts of melamine cyanurate, 2 parts of antimony trioxide, 10 parts of fatty alcohol polyoxyethylene ether, 4 parts of pentaerythritol, and 18 parts of ethanol.

[0053] The dipping solution is prepared from the following raw materials in parts by weight: 8 parts of fatty alcohol polyoxyethylene ether, 4 parts of epoxy resin, 2 parts of melamine cyanurate, and 250 parts of soft water.

Abstract

The invention discloses a production process for manufacturing a flame-retardant canvas bag from waste textiles, and relates to the technical field of canvas bag manufacturing. The technological process comprises the steps of waste textile pretreatment, melt spinning, flame-retardant finishing, spinning and weaving, padding treatment, and printing and sewing. Continuous cutting, smashing and magnetic separation are carried out through cutting, smashing and magnetic separation integrated equipment to obtain polyester fiber short filaments which are fixed in specification, free of metal impurities and high in cleanliness, and then cleaning liquid dipping, filtering and drying are carried out through dipping, filtering and drying equipment to obtain separated fiber short filaments which are free of oily impurities and high in cleanliness; in the flame-retardant finishing and padding treatment procedures, a flame retardant and a dipping liquor both contain flame-retardant components, and regenerated fiber filaments and a canvas are subjected to flame-retardant finishing, so that the heat-resistant and flame-retardant performance of the canvas bag is improved; and the moisture absorption and air permeability performance, strength and heat-resistant and flame-retardant performance of the canvas bag are improved by adding cotton fibers and aramid fibers in the spinning and weaving procedure.

Description

technical field [0001] The invention relates to the technical field of canvas bag manufacturing, in particular to a production process of using waste textiles to manufacture flame-retardant canvas bags. Background technique [0002] Canvas bags are bags made of canvas. As more and more people advocate environmental protection, canvas bags gradually enter into daily life, and designers add fashion elements to them, which makes canvas bags gradually become popular. Canvas bags are relatively environmentally friendly, and their durability and firmness are much higher than non-woven bags. [0003] The flame-retardant canvas in the prior art is generally prepared through the processes of yarn composition ratio, spinning, weaving, dipping liquid preparation, and padding treatment. The weaving process uses an air-jet loom or an arrow shaft loom. The following process is carried out: singeing, desizing, scouring, bleaching, mercerizing, dyeing, flame retardant, ammonia fumigation, ...
