This invention discloses a high abrasion-resistant textile yarn and its production process, belonging to the field of textile yarn technology. The process includes the following steps: Step S1: Abrasion-resistant filament and cotton yarn are twisted together at a distance of 2-3 mm, following a Z-twist direction and a twist of 110-115 twists / 10cm on a ring spinning machine, and then wound to obtain a composite yarn; Step S2: Another abrasion-resistant filament and the composite yarn are combined at a speed of 250-255 m / min using a doubling device, and then twisted on a doubling machine following an S-twist direction and a twist of 50-55 twists / 10cm, so that the abrasion-resistant filament is tied to the composite yarn in the opposite direction, resulting in a high abrasion-resistant textile yarn. This invention uses two abrasion-resistant filaments intersecting to form a mesh structure, with cotton yarn wrapped within it as the core yarn. The resulting high abrasion-resistant textile yarn has a low twist, retaining the softness of the internal cotton yarn while significantly improving the abrasion resistance of the textile yarn.

This application relates to the field of fabric printing technology, and more specifically, to a method for printing 3D patterns on fabric and its products, comprising the following preparation steps: designing a pattern: designing a pattern according to requirements; preparing templates: preparing complementary and interlocking convex and concave double templates according to the pattern, wherein the convex template corresponds to the raised area of ​​the pattern, and the concave template corresponds to the recessed area of ​​the pattern; molding: placing the part of the fabric to be printed between the convex and concave double templates, molding, removing, and obtaining an uneven pre-treated fabric; printing: inkjet printing on the uneven pre-treated fabric, fixing the color, and post-processing to obtain a 3D patterned fabric. Through the above process, a 3D three-dimensional printed fabric with a distinctly tangible convex and concave feel, realistic visual three-dimensional effect, good softness and breathability is obtained, effectively solving the technical problem that the three-dimensional effect and wearing comfort cannot be achieved simultaneously in existing physical modification technologies.

This invention discloses a modified PU leather with fragrance-locking microcapsules and its preparation method, belonging to the field of PU leather processing technology. Addressing the shortcomings of traditional PU leather (resin odor), existing fragrance-adding methods (easily damaging leather and short-lasting scent), and the incompatibility of textile microcapsule technology with PU leather, this invention utilizes polyurethane-gelatin composite wall materials and fragrance microcapsules with a particle size of 3-8 μm. An impregnation solution is prepared using a neutral nonionic penetrant. The PU leather blank is immersed in the impregnation solution at 30-40℃ for 8-12 minutes, allowing the microcapsules to penetrate into the inner layer of the leather. It is then dried in a hot air oven at 60-70℃ for 15 minutes to achieve tight adhesion between the microcapsules and the leather fibers. This invention effectively removes odors and provides long-lasting fragrance to PU leather. Even after 30 wipes or 10 washes, the fragrance remains sensorily identifiable. The entire process is gentle, does not damage the leather surface, and fully preserves its original softness, luster, and abrasion resistance.

The invention provides a manufacturing method of modal and blended knitted fabric thereof, which specifically comprises the following steps: S1, singeing: quickly passing gray fabric of modal cotton blended knitted elastic plain cloth fabric through a burner of a singeing machine, and burning off hairiness on the surface of the fabric; s2, boiling off and bleaching: boiling off and bleaching the singed gray fabric by adopting a high-temperature overflow dyeing machine; s3, in-cylinder loose mercerizing: directly performing loose mercerizing treatment on the boiled and bleached wet cloth in a high-temperature overflow dyeing cylinder; s4, reactive dyeing: dyeing the fabric subjected to the loose mercerizing treatment by using a reactive dye according to a required color, and fixing the color by using sodium carbonate; s5, soaping: soaping the dyed fabric to remove flooding; s6, tentering and shaping; s7, preshrinking is carried out; and S8, finished product inspection and the like. The defects that modal and blended knitted fabric thereof are prone to deformation and pilling are overcome, meanwhile, the elasticity and resilience of the fabric are improved, and the fabric is endowed with soft, glutinous and smooth hand feeling, easy-care, crease-resistant and good in gloss after being washed.

The application provides an anti-static knitted fabric based on charge accumulation and directional guidance, a preparation method thereof and a knitted fabric, and belongs to the technical field of knitted clothes. The first spinning component and the second spinning component are co-extruded through melt spinning to prepare a composite fiber with a parallel composite structure, and a composite yarn is obtained through thermal mechanical treatment; the composite yarn is introduced into a specific area of the fabric in a tuck-welt organization through an inlaying process, and latent crimping is activated through after-finishing. The application utilizes the hygroexpansion of the second spinning component to drive macroscopic self-crimping of the composite yarn, and constructs an efficient conductive framework by physical extrusion of the internal conductive filler, so that humidity response adjustment of the anti-static performance and directional dissipation of the charge are realized, the problems of fixed conductive state, local static accumulation and poor comfort of the existing fabric are effectively solved, and the safety and wearing experience of the clothes are improved.
