Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 73 words
A process for the preparation of chains or fractions of continuous, synthetic, completely-drafted yarns, wound on weaving beams, suitable for all types of loom-produced textiles, using a series of at least 24 continuous, thermoplastic yarns made of substantially parallel and partially drafted filaments, which are simultaneously and contemporaneously drafted when immersed in a vat containing a thermostatic liquid followed by an interlacing treatment using a fluid jet, and then by a sizing treatment.
Claim 2
Dependent Claim 73 words
A process for the preparation of chains or fractions of continuous, synthetic, completely-drafted yarns, wound on weaving beams, suitable for all types of loom-produced textiles, using a series of at least 24 continuous, thermoplastic yarns made of substantially parallel and partially drafted filaments, which are simultaneously and contemporaneously drafted when immersed in a vat containing a thermostatic liquid followed by an interlacing treatment using a fluid jet, and then by a sizing treatment.
Claim 3
Dependent Claim 25 words
A process, in accordance with Claim 1, where the interlacing process, which follows drafting, is carried out on the yarn while it is still humid.
Claim 4
Dependent Claim 26 words
A process, in accordance with Claim 1, where the interlacing treatment is carried out by means of a device which also provides voluminization of the yarn.
Claim 5
Dependent Claim 26 words
A process, in accordance with one of the preceding claims, where the thermoplastic yarns are of the following types: polyesters, polyamides, polyethylenes, polypropylenes and their modifications.
