Description

Pure nylon carrying tool fabric printing production process
Technical Field
The invention relates to the technical field of textile printing and dyeing, in particular to a pure nylon carrying tool fabric printing production process.
Background
The carrying tool fabric is a harness for individual soldiers to carry weapons and ammunition, protective articles and personal articles when the military is used for individual soldiers to transfer and mobilize, and comprises the following parts: a purse, a backpack, a multipurpose strap, etc. Because the load of the individual soldier directly influences the combat effectiveness and the endurance capacity of the individual soldier, the military and the strong countries in the world pay great attention to the development of the individual soldier carrying tool, and due to the special application of the individual soldier carrying tool, the material of the individual soldier carrying tool has the requirements of ultra-strong wear resistance and durability, and the world generally adopts a waterproof pure nylon material at present; polyamide is commonly called Nylon (Nylon), is also called chinlon in China, is called Polyamide in English, and is a general name of a high polymer containing amide groups in a main chain repeating unit of a macromolecule. The nylon fiber has good comprehensive properties including mechanical property, heat resistance, abrasion resistance, chemical resistance and self-lubricity, and is low in friction coefficient, certain in flame retardance and easy to process. The varieties of chinlon are various, including PA6, PA66, PA11, PA12, PA46, PA610, PA612, and PA PAl010, and new varieties such as semi-aromatic nylon PA6T and special nylon developed in recent years. In China, the development of the single-soldier carrying tool fabric is late, the whole body of the single-soldier carrying tool fabric lags behind the western developed countries such as America, English, Germany and the like, and the single-soldier carrying tool fabric is not mature at present in the camouflage printing process and the product of the pure nylon carrying tool fabric.

3. oxygen bleaching: adding low-temperature refining agent 10KG and hydrogen peroxide (H) into 350L of caustic soda NaOH (28-degree Be')/2O2) 50KG is synthesized into 1000L oxygen bleaching working solution with pH value of 9-10, and the fabric is fully soaked at normal temperatureThe working solution is uniformly rolled and pressed and then enters a steaming box for steaming, the temperature of the steaming box is 60-80 ℃, the steaming time is 50-60 minutes, and the working solution is fully washed and dried;
4. shaping: the temperature of the drying room is 170-;
5. printing: printing the pure nylon carrying tool fabric, wherein patterns and colors are according to the requirements of users; when preparing printing color paste, carrying out laboratory sample imitation according to the hand sample prescriptions of color paste with different colors, and selecting the types of acid dyes and coatings to prepare color paste with color spots;
6. long-ring steaming: the temperature of the steaming box is 105-110 ℃, the humidity is optimized to be 70-80% (different from an intermittent tank steaming machine), and the steaming time is 30-35 minutes;
7. soap (water) washing: soaping in a soaping box which synthesizes 400L of soaping liquid by using 10KG of acidic soaping agent and 2KG of chelating dispersant at the temperature of 90-95 ℃, and keeping the soaping liquid for continuous feeding; fully washing with water and drying;
