Description
Technical Field
The invention relates to the technical field of nylon fabrics, in particular to a nylon Long Chaoliang bark wrinkled fabric and a manufacturing process thereof.
Background
With the development of economy and the continuous improvement of living standard of people, the textile fabric industry is facing the unprecedented challenges and opportunities, however, the demands of consumers on textile fabrics are not limited to basic wearing functions, but the demands are more focused on the visual sense aesthetic feeling, the body feeling comfort and the multifunctionality of the fabrics, especially in the fields of outdoor exercises, fashion clothes, high-end home decoration and the like, the higher demands are put forward on the performances of the textile fabrics such as water resistance, fluff prevention, warmth retention, durability and the like, in recent years, the market is provided with the fabric imitating bark, namely the bark wrinkled fabric, the unique texture and the three-dimensional sense of the bark wrinkled fabric are deeply loved by consumers, however, the bark wrinkled fabric in the current market is mostly made of materials such as cotton, polyester and the like, which are difficult to be compared with nylon in gloss and wear resistance, the characteristics such as excellent wear resistance, chemical resistance and self-lubricating property, but the limitations are present in gloss and texture diversity, the market is difficult to meet the requirements on high-end and individuation, in the prior art, the processing process of the nylon fabric usually comprises desizing, drying, the steps, the barks are difficult to produce the problems of being difficult to produce, the problems of poor in the appearance, such as poor in the comfort performance, the appearance, the anti-wearing effect is easy, the nylon fabric is poor in the appearance, the comfort performance is not easy to have, the problem of the anti-wearing, and the anti-static effect is easy, and the anti-static material is poor, and the anti-touch performance, and the anti-wearing problem.
Disclosure of Invention
In order to overcome the technical defects in the prior art, the invention provides the nylon Long Chaoliang bark wrinkled fabric and the manufacturing process thereof, wherein the nylon Long Chaoliang bark wrinkled fabric has high fault tolerance rate in preparation, and after the preparation is finished, the fabric cloth has the characteristics of excellent water resistance, stain resistance, sterilization, static resistance, fluff falling prevention, pilling resistance, durability, gloss, wrinkling style, excellent heat preservation performance and the like.
The technical scheme includes that the nylon Long Chaoliang bark wrinkled fabric comprises a embryo cloth layer, a degerming antistatic layer, a thermal layer and an anti-fouling waterproof layer which are compounded in sequence, wherein the embryo cloth layer is in compound connection with the degerming antistatic layer through a bonding layer, the embryo cloth layer is nylon 20D embryo cloth, the degerming antistatic layer is a blended fabric made of 50% of antistatic fibers and 50% of degerming fibers in a blending mode, ventilation holes are reserved in the middle of the blending process, the antistatic properties and the degerming properties of the fabric can be guaranteed under the condition that the fabric is light and thin in the blending mode of the antistatic fibers and the degerming fibers, the bonding layer is formed by a plurality of parallel hot melt adhesive films, the thermal layer is formed by spraying one layer of aerogel outside the degerming antistatic layer, and the anti-fouling waterproof layer is formed by baking after the whole fabric is soaked with fluorine-free waterproofing agent ruff ECO.
Preferably, in order to ensure that the nylon 20D gray fabric with certain thickness, softness and air permeability is obtained, the nylon 20D gray fabric is woven by nylon filament blanks with the warp density of 225 and the weft density of 180, the nylon filaments are prepared by a melt spinning method of polyamide resin, the polyamide resin is heated to a molten state in the spinning process and then is extruded through a spinning hole of a spinning machine to form continuous filaments, the spinning speed is high, the spinning is higher than 3000m/min, the nylon material has good wear resistance, the nylon material also has good resistance to mould, the nylon filament gray fabric is easy to carry out subsequent dyeing, printing and other treatments, and the gray fabric has good physical properties such as tensile strength, elongation at break, elastic recovery rate and the like.
Preferably, in order to add an antistatic function to the fabric, the antistatic fiber is a stainless steel metal conductive fiber, the stainless steel metal conductive fiber is made of high-purity and high-corrosion-resistance stainless steel through a plurality of steps such as smelting and casting, rolling and drawing, heat treatment, surface treatment and coating, and the stainless steel metal conductive fiber has good conductive performance, and static charge can be quickly led into the ground, so that static accumulation is effectively prevented.
Preferably, in order to blend the degerming material with the antistatic fiber to prepare the degerming antistatic fabric, the degerming material can be uniformly distributed in the fiber, so that the durable degerming performance is provided for the fabric, and the degerming fiber is one or more of nano silver ion fiber, bamboo charcoal fiber and chitin fiber.
A preparation process of a nylon Long Chaoliang bark wrinkled fabric comprises the following steps:
step one, preparing cloth, namely respectively weaving the embryo cloth layer and the degerming antistatic layer, and bonding the embryo cloth layer and the degerming antistatic layer through a hot melt adhesive film of the bonding layer.
Desizing, namely desizing the prepared fabric at the temperature of 90-95 ℃ and the speed of 50-60m/min, and sequentially adding the following auxiliary agents according to the water quantity, namely adding 1-4 g/l of chelating agent at a constant speed within 5-10 minutes, 15-20 g/l of liquid alkali at a constant speed within 5-10 minutes, and 3-6 g/l of sodium dodecyl sulfate as a refining agent within 5-10 minutes;
Step three, shaping, namely baking the desized fabric at the speed of 40-50 yards/min and at the temperature of 170 ℃ to form;
