A portable patchwork sewing tool kit includes: a base plate, the inner face thereof is provided with a first page and a second page which can be folded or unfolded optionally; a rotary cutting mat fixed to the first page, the rotary cutting mat comprises a bottom plate and a cutting plate pad screwed on the bottom plate through a pivot joint base to be rotated under stress; a detachable ironing mat fixed to the second page, including a core board, a cotton spreading layer covering the core board and a cotton fabric surface layer covering the cotton spreading layer, an ironing face formed outside the cotton fabric surface layer; and a plurality of pushing edges formed around the cutting plate pad and spaced apart.

An attachment for a sewing machine to provide simultaneous sewing and sealing of a seam comprises a reel for dispensing a strip of adhesive thermoplastic polymer between fabric members to be sewn. A plurality of heated driven rollers opposed to heated idler rollers having a continuous belt thereover collectively exert heat and pressure on the seam, melting the polymer strip so as to seal the seam. Thread having been treated with adhesive thermoplastic polymer may be employed to seal the punctures in the fabric made by the sewing machine's needle. The driven rollers are driven in synchronization with the operation of the sewing machine, and are engaged with and withdrawn from the seam responsive to operator command.

The present application discloses a softening device (200) by which an outer insulating layer of an elongate electrical heating element (121) to be secured onto a cushion, especially a vehicle seat or rest cushion is able to be softened, the softening device (200) comprising: a body (210), wherein the body is provided with a gas passage, a feeding passage (211), and an open cavity (213), wherein hot air is able to be driven through the gas passage, and the elongate electrical heating element (121) is able to be conveyed through the feeding passage (211), wherein the gas passage and the feeding passage (211) are isolated from each other but both of them open into the open cavity (213), wherein after passing through the feeding passage (211) and the open cavity (213), the electrical heating element (121) is able to be discharged out of the body (210). The present application also discloses an electrical heating element (121), a sewing apparatus comprising the softening device, and a method for controlling the softening device.

An article comprised of tape segments embroidered in place is disclosed. One embodiment includes tape segments embroidered to a self-supporting embroidered structure. Another embodiment includes tape segments embroidered together to form an embroidered lattice structure. In one embodiment, some of the tape segments may expand when exposed to heat and may be used to form cushioning regions for the article.

An artificial turf system is for installation over a receiving surface. The artificial turf system comprises a flexible sheet member to be laid over the receiving surface via its lower surface. It comprises first yarns having a first melting point; second yarns, distinct from the first yarns and having a second melting point; and third yarns, having a third melting point, with all yarns extending upwardly from the upper surface of the sheet member. The third melting point is lower than the first and second melting point. The artificial turf system undergoes a heat treatment at a temperature higher that the third melting point prior to installation through which third yarns at least partially fuse with part of one of the first yarns and the second yarns. Further described is a method of manufacturing the artificial turf system.

A method for producing a textile product (I), (II), comprising at least two synthetic pile threads (P1), (P2) having a different pile height, so that a predetermined design is formed, in which the synthetic pile yarns (P1), (P2) are manufactured by extrusion from the same raw material, according to production processes which only differ from each other by a different setting of one or several process parameters of their respective extrusion processes, so that they have a different shrinking capability, and in which the textile product (I), (II) is subjected to a heat treatment which causes the pile yarns (P1), (P2) to shrink differently. Also such a method for producing synthetic textile yarns (P1), (P2) having a different shrinking capability.
