Custom Brocade Ammonia Knitted Elastic Fabric For Underwear

What raw materials are usually used for brocade Ammonia Knitted Elastic Fabric for underwear? What pretreatment does the raw material need before weaving?

Brocade ammonia knitted elastic underwear fabric occupies an important position in the underwear market with its excellent elasticity, comfort and breathability. This type of fabric is usually composed of two major fiber components: nylon (nylon) and spandex, each of which plays a different role:
Nylon (nylon): As the main structural fiber, nylon is famous for its high strength, good wear resistance, and strong wrinkle resistance. Among nylon fabrics, nylon provides the basic strength and morphological stability of the fabric. JUNRUI Company specially selects environmentally friendly nylon fibers. These fibers adopt more environmentally friendly polymerization technology and spinning process during the production process, reducing the emission of harmful substances and complying with international environmental protection standards such as OEKO-TEX. By improving the cross-sectional shape of the fiber (such as special-shaped cross-section), the moisture wicking performance and gloss of the fabric can be further improved, and the wearing comfort can be enhanced.
Spandex: As an elastic fiber, spandex is known for its extremely high elongation and good recovery, giving nylon and spandex fabrics excellent elasticity. Among JUNRUI's products, the selection of spandex also pays equal attention to environmental protection and performance. The company uses bio-based or recycled spandex. These spandex fibers are derived from renewable resources or waste textile recycling, effectively reducing dependence on fossil resources and environmental pollution. The fine blending proportion design ensures that the fabric has sufficient elasticity without losing softness and comfort.
Before raw materials enter the weaving process, a series of delicate pre-processing steps are crucial, and they are directly related to the quality and performance of the final fabric. With its advanced technology and strict quality control system, JUNRUI has achieved the following points in raw material pretreatment:
Fiber modification treatment: In order to improve the spinnability of the fiber and the functionality of the fabric, JUNRUI will modify nylon and spandex. This includes antistatic treatments, antimicrobial treatments, and treatments that improve the hydrophilic or hydrophobic properties of fibers. These modification technologies not only enhance the durability and wearing comfort of the fabric, but also make the fabric easier to care for and reduce energy and water consumption during the washing process.
Environmentally friendly sizing: Before weaving, fibers usually need to be sizing to improve their weavability and prevent the fibers from breaking or getting entangled during the weaving process. JUNRUI uses bio-based or degradable slurries, which are made from natural plant extracts or microbial fermentation products. Compared with traditional chemical slurries, they can significantly reduce the impact on the environment. By precisely controlling the sizing amount and uniformity, we ensure the double improvement of weaving efficiency and fabric quality.
Precision cleaning and drying: Before the raw fiber enters the loom, it needs to go through a precise cleaning process to remove surface oil, dust and other impurities. JUNRUI uses efficient and energy-saving cleaning equipment and environmentally friendly cleaning agents to ensure the purity of the fiber. The subsequent drying process also strictly controls the temperature and humidity to avoid damage to the fiber due to overheating or overdrying and maintain its optimal physical properties.
Pre-drafting and shaping: For spandex fiber, pre-drafting helps stabilize its elastic properties and reduce deformation during the weaving process. Nylon fiber may need to be preheated and set to improve its dimensional stability and wrinkle resistance. JUNRUI uses advanced heat setting equipment, combined with precise temperature and time control, to ensure that each batch of fibers can achieve the ideal pretreatment effect.
In the production process of brocade Ammonia Knitted Elastic Fabric for underwear, JUNRUI not only pays attention to the selection of raw materials and environmental protection, but also strives for excellence in pre-treatment technology. By using environmentally friendly raw materials, bio-based slurry, precision cleaning and drying technology, and scientific pre-drafting and shaping treatments, the high quality and environmentally friendly properties of the fabric are ensured. The company's technical advantages are not only reflected in its keen capture of international fashion trends and product design innovation, but also in its strict control of every link in the production chain and in-depth implementation of environmental protection concepts. Whether it is complex custom orders or large-scale production needs, JUNRUI can rely on its stable supply chain, efficient production capacity and strict quality control to provide customers with high-quality underwear fabric solutions that are both in line with fashion trends and environmentally friendly. . It is this comprehensive advantage that allows JUNRUI to stand out in the fierce market competition and become a leader in the industry.
