The present invention relates to the technical field of polyamide materials, and specifically relates to a polyamide sea-island fiber and a process for producing the same and the use thereof. In the polyamide sea-island fiber, the island component is a polyamide resin selected from one of polyamide 56, polyamide 510, polyamide 511, polyamide 512, polyamide 513, polyamide 514, polyamide 515 and polyamide 516, preferably polyamide 56 or polyamide 510; the sea component is one of polyethylene, low-density polyethylene, polystyrene, water-soluble polyesters, polyesters and polyurethanes, preferably polyethylene, low-density polyethylene or water-soluble polyester. The polyamide sea-island fiber of the present invention has better mechanical properties, better softness, good dyeing properties, high grade of dyeing grey scale, high dye uptake, high dyeing depth and high color fastness.

Disclosed in the present invention is a polyamide 5X industrial yarn. The polyamide 5X industrial yarn has a heat-resistant break strength retention rate of 90% or more after being treated at 180° C. for 4 hrs; a heat-resistant break strength retention rate of 90% or more after being treated at 230° C. for 30 mins; and a dry heat shrinkage of 8.0% or less. The polyamide 5X industrial yarn is widely used in the fields of sewing threads, tire cords, air bag yarns, release cloth, krama, canvas, safety belts, ropes, fishing nets, industrial filter cloth, conveyor belts, parachutes, tents, bags and suitcases.

A method of generating a coiled actuator fiber that includes twisting a fiber to generate a twisted fiber; wrapping the twisted fiber around a core yarn or fiber to generate a coil in the twisted fiber, which generates a coiled twisted fiber; setting the coiled twisted fiber by heat or chemical treatment; and removing at least a portion of the core yarn or fiber to generate a coiled actuator fiber.

Disclosed is a compression and/or contention garment for lymphoedema treatment, the garment including a main body made of a compression textile. The garment has at least a first targeted area, in which the garment includes at least one layer of reinforcement textile, and at least a second targeted area, in which the garment includes at least one layer of contention textile.

Silk infused performance apparel and methods of preparing the same are disclosed herein. In some embodiments, silk performance apparel includes textiles, fabrics, consumer products, leather, and other materials that are coated with aqueous solutions of pure silk fibroin-based protein fragments. In some embodiments, coated apparel products, textiles, and upholstery, as well as other materials, exhibit surprisingly improved moisture management properties, resistance to microbial growth, increased abrasion resistance, and flame resistance.

Disclosed is a textile sliding surface with a functional layer (1) and a base layer (2), which are connected to each other by filament yarns. The functional layer (1) is formed of pile loops, whereby the height of the pile loops in the functional layer (1) has a height (4), depending on the sport, in the range 4-1 4 mm and the functional layer (1) has 400-2400 pile loops per dm.sup.2. The yarns are bound into the base layer (2) in the lower part of the pile loops by W-bonds (10).

The present invention relates to a tire cord having excellent durability while being thin in thickness, a manufacturing method thereof and a tire comprising the same.

A covered yarn material for a heating blanket felt, a covered yarn, and a woven product thereof are provided. The covered yarn material includes a skin-layer material and a core-layer material, where the skin-layer material includes 20 wt % to 30 wt % of a powder melt mixture and 80 wt % to 70 wt % of a mixed-melt raw material; the core-layer material includes 100 wt % of a core-layer filament; the powder melt mixture is composed of the following components: 20 wt % of a carbon nanotube (CNT), 35 wt % of a graphite powder, 25 wt % of a copper powder, and 20 wt % of a jade ore powder; the mixed-melt raw material includes one or more from the group consisting of polyethylene terephthalate (PET), polyamide (PA) 6, PA66, polyphenylene sulfide (PPS), liquid crystal polymer (LCP), and polycarbonate (PC); and the core-layer filament includes one or more from PET, PA66, PPS, and LCP.
