Description

Technical Field

[0001] The invention belongs to the field of textile technology, and more specifically, particularly relates to a manufacturing process of outdoor fabrics. Background Art

[0002] With the continuous improvement of people's living standards and the increasing popularity of outdoor sports, the demand for outdoor fabrics is showing a rapid growth trend. Outdoor fabrics not only need to have basic textile properties, such as softness, comfort, durability, etc., but also need to perform well in special properties such as waterproof, breathable, wear-resistant, and weather-resistant to adapt to the complex and changeable outdoor environment.

[0003] In the past, traditional outdoor fabric manufacturing processes had many limitations. Early waterproofing treatments usually used coating or lamination methods, but these methods often resulted in poor breathability of the fabric, which caused a stuffy feeling when worn and affected comfort. In addition, traditional processes were not satisfactory in terms of wear resistance and weather resistance. The fabric was easily damaged by frequent friction and adverse climatic conditions, shortening its service life.

[0004] At the same time, the selection and pretreatment of fiber raw materials are relatively simple. Common fiber materials have certain shortcomings in performance and cannot meet the increasingly demanding requirements of outdoor use. For example, although some fibers have good strength, they lack softness and elasticity; while other fibers perform poorly in terms of waterproofness or breathability.

[0005] In the spinning and weaving process, the technical level of traditional processes is relatively low, and it is difficult to achieve refined control. This leads to unstable yarn quality and uniformity, and unreasonable fabric structure, which affects the overall performance of the fabric.

[0006] In addition, there are some problems with the dyeing process. Traditional dyeing methods may result in low color fastness and easy fading, and a large amount of wastewater and pollutants may be generated during the dyeing process, causing great pressure on the environment.

[0007] Faced with the increasing quality requirements of outdoor products and the increasingly fierce market competition, the existing outdoor fabric manufacturing process can no longer meet the demand. Therefore, it is imperative to develop an innovative, high-performance outdoor fabric manufacturing process. This new process needs to comprehensively consider the optimal selection of fiber raw materials, advanced pretreatment technology, efficient spinning and weaving methods, environmentally friendly dyeing processes, and effective waterproofing and finishing treatments to produce outdoor fabrics with excellent waterproof, breathable, wear-resistant and weather-resistant properties, providing outdoor sports enthusiasts and related industries with better quality and more reliable product options. Summary of the invention

[0008] In order to solve the above technical problems, the present invention provides a manufacturing process of outdoor fabrics to solve the above problems.

[0009] A manufacturing process of outdoor fabrics comprises the following steps:

[0010] Step A: selecting polyester fiber and nylon fiber as fiber raw materials, and the mass ratio of polyester fiber to nylon fiber is 3:2;

[0011] Step B: pre-treating the fiber raw material, including washing at 50° C. for 15 minutes, and then drying at 80° C. for 30 minutes;

[0012] Step C: spinning the pretreated fiber using a ring spinning process, with a spinning twist of 1200 twists / m and a yarn count of 50S;

[0013] Step D: Weaving the spun yarns by a plain weaving method, with a warp density of 120 yarns / inch and a weft density of 80 yarns / inch to form a fabric grey cloth;

[0014] Step E: dyeing the fabric grey cloth, using reactive dyes, at a dyeing temperature of 85° C., for 60 minutes;

[0015] Step F: applying a waterproof coating on the dyed fabric, wherein the thickness d of the waterproof coating is calculated according to the following formula: d=0.05×(fabric weight G)^(1 / 2), wherein the unit of G is g / m2;

[0016] Step G: Finishing the fabric after applying the waterproof coating, including heat setting at a temperature of 150°C for 10 minutes.

[0017] Preferably, in step A, the linear density of the polyester fiber is 1.5 denier, and the linear density of the nylon fiber is 2 denier.

[0018] Preferably, in step B, the detergent concentration used during washing is 5 g / L, and the wind speed during drying is 10 m / s.

[0019] Preferably, in step C, the drafting multiple of spinning is 1.8 times, and the rotation speed of the spinning machine is 18,000 rpm.

[0020] Preferably, in step D, the twist of the warp yarn is 800 twists / m, and the twist of the weft yarn is 600 twists / m.

In summary, the outdoor fabric manufacturing process of the present invention can produce high-performance outdoor fabrics that meet different needs by reasonably adjusting the parameters of each step.

[0049] The outdoor fabric manufacturing process of the present invention successfully produces outdoor fabrics with excellent performance by carefully designing and optimizing each link. The feasibility and effectiveness of the process have been proven through verification and performance testing of multiple embodiments. In the future, with the continuous advancement of technology and changes in market demand, the process will continue to be optimized and improved to meet the growing market demand for outdoor products.

[0050] By carefully selecting fiber raw materials, optimizing weaving structures, and applying specific waterproof coatings, the fabric can effectively block the penetration of rain and moisture, providing users with reliable waterproof protection in outdoor environments. Whether in heavy rain or humid climate conditions, it can keep the inside dry, ensuring waterproof effect while achieving good breathability. Reasonable fiber ratio, spinning and weaving technology, and carefully designed fabric structure allow air to flow freely in the fabric, effectively discharging moisture and heat generated by the body, improving wearing comfort and avoiding stuffiness and discomfort;

[0051] The use of high-quality fiber raw materials and optimized weaving technology greatly enhances the wear resistance of the fabric. After repeated friction and use, it can still maintain a good appearance and performance, extending the service life of the outdoor fabric and enabling it to withstand various frictions and wear in the outdoor environment. After special treatment and material selection, the fabric can resist the influence of harsh outdoor conditions such as ultraviolet rays, temperature changes and humidity changes. During long-term outdoor exposure, the color remains stable and the strength loss is small, ensuring the long-term stability of the performance and appearance of the fabric. By adjusting the proportion of fiber raw materials, spinning and weaving parameters, dyeing process, and coating thickness, etc., outdoor fabrics with specific performance and characteristics can be produced according to different application needs and market requirements to meet a variety of outdoor application scenarios;
