20210299914 · 2021-09-30 ·

A method of manufacturing bulked continuous carpet filament that includes providing a polymer melt and separating the polymer melt from the extruder into at least eight streams. The multiple streams are exposed to a chamber pressure within a chamber that is below approximately 25 millibars, or another predetermined pressure. The streams are recombined into a single polymer stream. Polymer from the polymer stream is then formed into bulked continuous carpet filament.

Method for producing textile products, products obtainable therefrom and method to reclaim the products

The present invention pertains to a method for manufacturing a laminated textile product comprising providing a first intermediate product comprising a primary backing having a front surface and a back surface, and yarns stitched into the primary backing, the yarns extending from the front surface of the backing material, feeding the intermediate product along a body having a heated surface, the back surface being pressed against the said heated surface, to at least partly melt the yarns present in the intermediate product to bond the yarns to the backing, wherein the part of the back surface that is pressed against the heated surface has a relative speed with respect to the heated surface, so as to provide a second intermediate product having a calendered back surface, providing a dimensionally stable carrier sheet or secondary backing, and connecting the second intermediate product to the carrier sheet by providing a hot melt adhesive between the calendered surface and the sheet, and pressing the sheet to the second intermediate product to form the textile product.

Method for producing a textile product

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.

20210180223 · 2021-06-17 ·

The invention relates to the light industry area, namely to material for production of the woven and knitted textiles, and can be used for the manual production of the carpets, runners, coverlets, blankets and other similar decorative objects. The object of this utility model consists in improvement of material for production of the woven and knitted textiles by way of the optimum combination of the material composition and texture (form) resulting in upgrading of its application characteristics, namely—getting softness, lightness, strength and elasticity in combination with the aesthetic and decorative properties. In addition, the diversification of products made of the applied material is present. Material for production of the woven and knitted textiles is composed of the tubular seamless knitted shell filled with a reinforcing filler, made of synthetic microfiber or of a mixture of synthetic and natural microfibers with a density of 0.010-0.030 g/cm.sup.3, and the shell is made of the cotton or wool added with a synthetic thread, at that the material diameter is not more than 8 cm, and the shell and the filler composition ratio are defined by the material functionality.

A Tufting Machine and Method for Operating a Tufting Machine

A pattern data processing system configured to determine and compensate for any points of entanglement between different yarns. A point of entanglement is defined as a point where the yarn from one needle crosses and traps the yarn from another needle on the back face of the backing medium. The pattern data processing system is configured to calculate the additional length of back stich caused by each point of entanglement by subtracting an ideal back stich length, calculated as the path which would have been taken by the yarn had it not been entangled in another yarn, from an actual yarn path, calculated as the actual length of the entangled yarn. A controller is configured to include in the amount of yarn fed by a respective yarn feed mechanism for each stitch an amount equivalent to the additional length of back stitch. The invention also includes a tufting machine and method of operating the tufting machine with the pattern data processing system.
