Microfiber Synthetic Leather

This micro‑fiber PU synthetic leather features compact three‑dimensional micro‑fiber inner structure, delivering delicate and soft hand‑feel highly comparable to genuine leather. It possesses stable and balanced tensile and tear resistance and resists breakage under long‑term tension and repeated flexing. Its surface is covered with dense and complete PU resin coating for excellent color fastness; no discoloration, whitening or mottling occurs under long‑term sweat immersion, walking friction and repeated washing. Moderate hardness enables outstanding hot‑press shaping performance. Thin grades are skin‑friendly for shoe linings, while standard‑thickness versions apply to hot‑press lamination for shoe insoles, providing sufficient supporting strength together with comfortable wearing experience. It offers excellent bonding performance compatible with both cold‑glue and hot‑glue lamination processes in shoemaking. Benefiting from low water‑absorption rate, it effectively prevents swelling, deformation and collapse caused by foot sweat and moisture when used for shoe linings and insole surface materials.

Strict mass‑production control monitors roll thickness and surface texture uniformity for each batch. Stable shrinkage during automatic cutting reduces dimensional deviation, material loss and defective output. The surface is treated with anti‑pilling and scratch‑resistant finishing to avoid fuzzing and scratch damage under long‑term friction and extend service life of casual sneakers and daily‑wear shoes. It shows superior die‑cutting performance with smooth burr‑free cut edges, decreasing manual trimming workload for uppers and insoles. Excellent flex‑fatigue resistance ensures no cracking or PU‑coating peeling after tens of thousands of folding cycles.

Manufactured with eco‑friendly formula, the leather is low‑odor and complies with domestic and overseas footwear environmental standards for both domestic sales and export mass production. Widely supplied to sneaker factories, insole manufacturers and footwear‑accessory suppliers, this micro‑fiber PU leather can be processed into upper components, full shoe linings, insole surface covers and heel‑counter reinforcement sheets for running shoes, casual shoes, business casual shoes and safety work shoes, supporting both sample development and mass‑volume production. Follow standardized processing: unroll and lay flat the whole roll before marking and cutting to release internal winding tension and prevent dimensional deviation of cut pieces. Prior to mass hot‑press lamination, run sample adhesion test with dedicated shoe glue and start full‑scale production only after qualified bonding strength is confirmed. Reserve proper shrinkage allowance during layout for hot‑press forming to avoid high‑temperature‑induced deformation. Seal unfinished roll ends with waterproof film after daily processing to protect surface from dust, glue stain and moisture‑triggered PU‑coating aging. Stack cut pieces flat; heavy long‑term compression is forbidden to avoid permanent indentation on fine grain surface.

Standard warehouse storage requirements: store leather rolls flat in cool, dry and well‑ventilated warehouse. Keep away from prolonged sunlight exposure and high‑heat sources to prevent PU‑coating aging, discoloration and loss of flexibility. Isolate rolls from oily solvents and corrosive chemicals to avoid surface erosion. Handle rolls gently to prevent scratches from sharp hard objects. Complete graded QC and daily‑maintenance system: inspect roll sealing condition and surface cleanliness before daily cutting operations.

Random sampling inspection is carried out for every incoming batch to verify thickness uniformity, surface peel strength and flex‑crack resistance for strict incoming quality control. Adjust hot‑press temperature and pressure according to actual leather thickness before large‑scale automatic processing to guarantee consistent lamination effect. Clean leather trimmings from cutting can be collected for industrial recycling to reduce workshop waste and support low‑carbon circular shoemaking. Compared with ordinary PU synthetic leather on market, this micro‑fiber leather features enhanced tear strength from micro‑fiber substrate, genuine‑leather‑like soft touch, superior flex‑fatigue resistance against cracking & peeling, low water‑absorption for anti‑deformation, high sweat‑&‑wash‑resistant color fastness, compatibility with cold & hot glue lamination, burr‑free die‑cutting machinability and low‑odor export‑grade environmental performance. It is a mainstream high‑end footwear material for uppers, linings, insole surfaces and heel‑counter reinforcements of sneakers.
