What details should be paid attention to when sewing a tent?

Tent fabric selection and processing
Choosing the right fabric: is the basis for sewing a tent. Nylon fabric is light, durable and has good waterproof performance. It is more waterproof after special treatment; polyester fabric is economical, tough and suitable for popular products; cotton fabric has good breathability and comfortable touch, and is often used in leisure tents such as tent inner tents or sunshade tents with high comfort requirements. Fabric selection needs to comprehensively consider the purpose of the tent, the use environment and the user's requirements for different properties such as breathability and warmth.
Fabric pretreatment: The purchased tent fabric should be shrunk before cutting. It can be pre-washed in advance according to the shrinkage rate. It can be heated and boiled in a pure water solution for 15 minutes, cooled naturally, and then rinsed with pure water, and then flattened and dried, and then cut again.
Fabric cutting: According to the tent design drawings and size requirements, use professional cutting tools and equipment to accurately cut the fabric. When cutting, pay attention to the accuracy and edge flatness to avoid problems such as cutting and cutting that affect subsequent sewing. The fabrics in different parts should also be marked and classified to facilitate subsequent material and assembly.

Key points of sewing process
Thread selection: Nylon thread is strong, elastic and wear-resistant, and is suitable for tents with high strength requirements; cotton thread is tough, easy to color, and comfortable to the touch, and is suitable for leisure tents with high texture requirements; there are also some blended threads that combine the advantages of multiple fibers, such as strength and flexibility.
Sewing equipment and stitch selection: High-speed flat-bed sewing machines are suitable for sewing tent fabrics, which can improve production efficiency and ensure stitching quality. According to the thickness and strength requirements of the tent fabric, choose the appropriate stitch type, such as flat stitching, overlock stitching, etc., to ensure that the stitching is firm and beautiful.
Stitch length and tension control: The selection of stitch length needs to consider the purpose and strength requirements of the tent, generally between 8-12 stitches/inch. When sewing, the tension of the sewing machine should be reasonably controlled to ensure that the stitches are moderately tight to avoid problems such as uneven stitches, wrinkles or broken stitches.
Reinforcement treatment: The density, thickness or strength should be increased at the stress points and key parts of the tent, such as the corners, plackets, windows, etc., and double-needle or triple-needle stitching technology should be used to ensure the firmness and waterproofness of the tent seams.
Waterproof treatment
Waterproof coating: It is the key to the waterproof performance of the tent. The polyurethane coating has good flexibility, wear resistance and waterproofness, and can form a uniform waterproof film on the surface of the fabric; the silicone coating is environmentally friendly and non-toxic, has good air permeability, and has certain high temperature resistance; there are also some special coatings, such as fluoropolymer coatings, which have excellent waterproof, oil-proof and anti-fouling properties.
Joint treatment: The joints of the tent are the weak link of waterproofing and need to be treated with emphasis. The heat sealing machine can be used to heat-press the joints to seal the fabric and waterproof coating at the joints to prevent rainwater from penetrating from the joints. In addition, waterproof tape or waterproof sealing strips can be pasted on the joints to further enhance the waterproof performance of the tent.
Waterproof performance test: During the production process and after the completion of the tent, a waterproof performance test should be carried out to ensure that the waterproof performance of the tent meets the standard. Common test methods include hydrostatic pressure test, rain test, etc.

Frame production and installation
Material selection: The tent frame is generally made of aluminum alloy or carbon fiber. Aluminum alloy is light, strong and corrosion-resistant, which can meet the needs of most outdoor use environments; carbon fiber material is stronger and lighter, but the cost is relatively high.
Processing technology: The frame must be cut, bent and welded in strict accordance with the design requirements to ensure the accuracy of the size and welding quality. At the same time, the processed frame must be surface treated, such as spraying anti-rust paint or polishing, to improve its corrosion resistance and service life.
Installation and connection: Assemble the processed frame with the tent fabric to ensure a firm and reliable connection. Accessories such as screws and hooks can be used to connect the frame to the tent fabric. At the same time, attention should be paid to the coordination between the frame and the fabric to make the overall structure of the tent stable.

Accessory installation and detail processing
Zipper installation: Durable alloy zippers should be used for zippers to ensure wear resistance, strong tensile resistance and smooth opening and closing. During installation, it is necessary to ensure that the zipper fits smoothly with the tent fabric to avoid problems such as jamming and skipping teeth.
Velcro pasting: Velcro is used to fix tent fabrics, accessories or increase the sealing of tents. When pasting, ensure that its position is accurate, the pasting is firm, and it is tightly combined with the tent fabric to prevent loosening during use.
Placket and window processing: The placket and window of the tent are one of the key parts of waterproofing. The fabric of the placket should be made of durable and waterproof materials, and reinforced to improve its wear resistance and waterproofness; the sealing of the window should be ensured by using accessories such as waterproof zippers and sealing strips.

Finishing and packaging: After the tent is sewn, the tent should be carefully inspected, including the firmness of the stitching, the integrity of the accessories, and the waterproof performance, to ensure that the quality of the tent meets the standards. Then clean, dry and pack the tent. When packing, pay attention to protecting the fabric and frame of the tent to avoid damage during transportation and storage.
Quality Inspection
Sewing Quality Inspection: Randomly inspect and test the sewing quality of the tent to ensure that the stitches are tight, the lines are straight, there are no breaks, kinks, etc., and ensure the firmness and durability of the sewn parts.
Overall Structure Inspection: Check whether the overall structure of the tent is stable, including whether the frame is firmly installed, whether the connection is reliable, whether the placket and window open and close smoothly, etc., to ensure that the tent can withstand various external forces and environmental influences during use.
