Abstract
The invention discloses a production process for manufacturing a flame-retardant canvas bag by using waste textiles, and relates to the technical field of canvas bag manufacturing. The process flow comprises pretreatment of waste textiles, melt spinning, flame-retardant finishing, spinning and weaving, padding treatment and printing and sewing; continuous cutting, crushing and magnetic separation are carried out through cutting, crushing and magnetic separation integrated equipment, so that polyester fiber short filaments with fixed specifications, no metal impurities and high cleanliness are obtained, and then cleaning liquid dipping, filtering and drying are carried out through dipping, filtering and drying equipment, so that separated fiber short filaments without oily impurities and high cleanliness are obtained; in the flame-retardant finishing and padding treatment procedures, the flame retardant and the impregnating solution both contain flame-retardant components, the regenerated fiber filaments and the canvas are subjected to flame-retardant finishing, the heat-resistant flame-retardant performance of the canvas bag is improved, and the moisture absorption and air permeability, the strength and the heat-resistant 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
The invention relates to the technical field of manufacturing of canvas bags, in particular to a production process for manufacturing a flame-retardant canvas bag by using waste textiles.
Background
The canvas bag is a bag made of canvas, along with the increasing advocacy of environmental protection, the canvas bag gradually goes into daily life, and designers have added fashion elements in the canvas bag, so that the canvas bag gradually fires. The canvas bag is relatively environment-friendly, and the durability and the firmness are far higher than those of the non-woven fabric bag.
The flame retardant canvas in the prior art is generally prepared through the procedures of yarn component proportioning, spinning, weaving, impregnating solution preparation and padding treatment, wherein the weaving procedure adopts an air jet loom or an arrow shaft loom and is carried out according to the following procedures: singeing, desizing, scouring, bleaching, mercerizing, dyeing, flame retarding, ammonia fumigation, oxidation, water washing, drying, baking and preshrinking; the process improves the adhesive strength of the canvas and ensures the flame retardant property of the canvas. However, the prior art for manufacturing the flame-retardant canvas bag by using the waste textiles has few reports, cannot ensure that the canvas bag has comprehensive performances such as moisture absorption, ventilation, strength, heat resistance, flame retardance and the like, and lacks matched equipment to remove dust particles and metal impurities in the textiles so as to improve the cleanliness of the textile fiber short filaments.
Disclosure of Invention
The invention aims to provide a production process for manufacturing a flame-retardant canvas bag by using waste textiles, which is used for solving the technical problems that the prior art cannot ensure that the canvas bag has comprehensive performances such as moisture absorption, ventilation, strength, heat resistance, flame retardance and the like, and meanwhile, the matched equipment is lacked to remove dust particles and metal impurities in the textiles so as to improve the cleanliness of textile fiber short filaments.
The aim of the invention can be achieved by the following technical scheme:
the production process for manufacturing the flame-retardant canvas bag by using the waste textiles comprises the following steps:
Pretreatment of waste textiles: washing and drying the collected waste textiles, and then performing continuous cutting, crushing and magnetic separation processes through cutting, crushing and magnetic separation integrated equipment to obtain textile fiber short filaments; washing liquid dipping, filtering and drying are carried out on the textile fiber short filaments through dipping, filtering and drying equipment to obtain separated fiber short filaments;
Melt spinning: after the separated fiber short filaments are heated and melted, spinning into filament bundles by a spinneret plate, and drying to obtain regenerated fiber filaments;

In the process of rotating the first rotating shaft (331) and the second rotating shaft (341), the first crushing shafts (343) and the second crushing shafts (345) also rotate along with the rotating shafts, and the first cutting knife (344) and the second cutting knife (346) which are mutually staggered cut and crush waste textiles, so that warps and wefts of the textiles are separated, and textile fiber short filaments are obtained through cutting and crushing for multiple times;
The cutting, crushing and magnetic separation integrated equipment carries out the concrete process of magnetic separation: starting a servo motor (431), wherein the servo motor (431) drives a rotary magnet (432) and a rotary drum (433) to rotate through a coupler (434), textile fiber short filaments float in a magnetic separation box (410) by wind power, and internal dust particles enter the rotary drum (433) through a through hole (435) to be collected and settled, wherein magnetic metal impurities can be adsorbed on the rotary magnet (432);
The specific processes of dipping, filtering and drying the cleaning liquid of the dipping, filtering and drying equipment are as follows: after the textile fiber short filaments are added from the feed inlet (501), the textile fiber short filaments fall onto the filter frame (530), the booster pump (590) is started, cleaning liquid is sprayed out of the liquid spraying head (593) through the liquid inlet pipe (591) and the liquid inlet cavity (592), the textile fiber short filaments are immersed and cleaned, the driving device drives the rotating gear (510) to rotate, the rotating gear (510) drives the lifting rack (520) meshed with the rotating gear to move upwards, and the lifting rack (520) drives the filter frame (530) to move upwards to the upper part of the cleaning liquid along the guide column (550); after the hot air blower (560) is started, the drying hot air is sprayed out through the hot air cavity (570) and the hot air pipe (580), and the impregnated textile fiber short filaments in the filter frame (530) are dried by blowing, so that the water and the liquid remained on the surface are removed.
