This invention discloses a shape-memory cotton fleece-like fabric, a method for preparing the fabric, and related applications such as clothing made from the fabric. The shape-memory cotton fleece-like fabric provided by this invention has a uniformly distributed microfibrillated pile structure on its surface. This invention also provides a method for preparing the aforementioned cotton fleece-like fabric, which includes: fabric preparation, pretreatment, dyeing, first liquid ammonia treatment, ammonia removal drying, mechanical napping, second liquid ammonia treatment (setting), softening finishing, pre-shrinking, and inspection. The shape-memory cotton fleece-like fabric provided by this invention has a microfibrillated pile structure on its surface. While retaining the advantages of cotton fabrics, this fabric has a unique, lasting, delicate, and rich fleece feel, with a soft hand like cashmere, and maintains good mechanical properties, achieving a balance between "strength" and "fleece."

The utility model belongs to the technical field of connecting pipe fittings, and particularly relates to a thermal shrinkage sealing connecting pipe fitting and a pipe fitting assembly, which comprise a pipe fitting body, the pipe fitting body is provided with a port, an internal thread is arranged on the inner side wall of the pipe fitting body close to the port, the outside of the pipe fitting body is coated with a cross-linked polyethylene insulating anti-corrosion layer, and the cross-linked polyethylene insulating anti-corrosion layer is coated with an anti-corrosion layer. And the end part of the cross-linked polyethylene insulating anti-corrosion layer extends towards one end far away from the port to form a thermal shrinkage sealing pipe section. The cross-linked polyethylene insulating anti-corrosion layer is arranged outside the heat-shrinkable sealing connecting pipe fitting, the service life is longer and can reach more than 50 years, the heat-shrinkable sealing pipe section has a shape memory function through heating expansion after radiation cross-linking, the heat-shrinkable sealing pipe section can wrap the outer side of a polyethylene anti-corrosion steel pipe in a heat-shrinkable mode, the sealing effect is achieved, and the service life of the heat-shrinkable sealing connecting pipe fitting is prolonged. External rainwater and the like are prevented from entering the threaded connection position between the thermal shrinkage sealing connection pipe fitting and the polyethylene anti-corrosion steel pipe to corrode threads, and the cross-linked polyethylene material has good insulation performance.
