    摘要： To provide a combined yarn producing device capable of suppressing swaying of a second group of yarns on rollers to which the yarns are guided so as to reduce possible damage to the yarns.
    The combined yarn producing device includes: heating rollers (31 to 35) configured to heat a first group of yarns (Y1) obtained as a result of dividing a plurality of yarns by a yarn dividing guide (11); a yarn feed roller (12) configured to cause the first group of yarns (Y1) to enter a heat retention box (30) from an inlet (30a); a yarn feed roller (13) to which the first group of yarns (Y1) caused to pass through the heating rollers (31 to 35) and leave the heat retention box (30) from an outlet (30b) are guided; a guide roller (36, 37) configured to guide a second group of yarns (Y2) obtained as a result of dividing a plurality of yarns by the yarn dividing guide (11) to the yarn feed roller (13) without causing the second group of yarns (Y2) to pass through the heating rollers (31 to 35); an interlacer (16); a yarn doubling unit (18); and a yarn combining guide (20) having a plurality of guide portions arranged along an axial direction upstream from the yarn feed roller (13) and the yarn doubling unit (18) in a yarn traveling direction, the plurality of guide portions configured to combine and guide the first group of yarns (Y1) and the second group of yarns (Y2).

    摘要： The present invention relates to a process for producing mixed yarns comprising at least one spun yarn of natural or artificial fibres and at least one synthetic or artificial filament yarn. This process involves compressed air interlacing of mixed yarns in a technological process mounted and/or adapted on textile yarn spinning machines carried out inside an interlacing device that isolates the spun yarn and the filament yarn during the interlacing process, protecting the production line from oligomer molecules and loose fibres. The present invention allows a combination of different types of yarns that are biodegradable and/or contain recycled raw materials to be mixed together, making it possible to immediately take action and prevent the chemical pollution of textiles and textile fibres in the environment and especially in the oceans.
    In addition, the present invention relates to mixed yarns derived from this process.

    摘要： The present invention relates to leather spun yarn with improved physical properties of the leather spun yarn by containing leather fibers longer than conventional leather fibers, in which the leather fiber has an average length of 15 mm or more and 40% or more of the content of fibers of more than 15 mm, in the leather fibers for the leather spun yarn contained in the leather spun yarn formed by containing the leather fibers and synthetic fibers.
