专利汇可以提供Process for making textured threads without twist recovery or untwisting专利检索，专利查询，专利分析的服务。并且Process for making textured threads which are not subject to twist recovery or untwisting, from synthetic fiber materials consisting of capillary fibers, with a view to obtaining the characteristics of native vegetable threads, comprising the steps of continuously feeding the fiber materials, e.g., from a doublewire spindle, through a feed zone where preferably tension is regulated, heating the materials so as to fix the twist applied thereto, successively cooling the materials, thereby strengthening their intermolecular structure, and subjecting the same to texturing, followed by optional winding up of the completed single or mixed textured threads.，下面是Process for making textured threads without twist recovery or untwisting专利的具体信息内容。

权利要求

1. A process for making single and mixed textured threads without twist recovery or untwisting, from synthetic, preferably continuous, filament or fiber materials, consisting of capillary fibers, comprising the steps of continuously feeding the fiber materials from a rotary organ such as a double-wire spindle through a feed zone, heating the materials in the latter, successively cooling the materials, and subjecting the same to texturing, followed by optional winding up of the completed single or mixed textured threads, whereby the characteristics of native vegetable threads are imparted.

2. The process as defined in claim 1, further comprising the step of controlling the moving speed of the fiber materials in the feed zone between pairs of feed-in and outlet rolls so as to regulate their tension.

3. The process as defined in claim 1, further comprising the step of cooling the fiber materials between the feed and the texturing zones so as to strengthen their intermolecular structure.

4. The process as defined in claim 1, further comprising the steps of forming at least one thread from the fiber materials at the rotary organ and imparting thereto a permanent twist.

5. The process as defined in claim 4, further comprising the step of fixing the twist applied to the at least one thread by said heating step in the feed zone.

6. The process as defined in claim 5, further comprising the step or bringing the fixed capillary fibers of the at least one thread into a diffuse state by the application of a fluid medium, such as in an adaptor provided in the texturing zone.

7. The process as defined in claim 1, for making mixed textured threads of the described characteristics, further comprising the step of feeding other fiber materials from a spool and the like and uniting the same with the fiber materials fed by the rotary organ.

8. The process as defined in claim 7, further comprising the steP of forming a thread from at least one of the fiber materials, fed from the rotary organ and from the spool, and wherein the fiber materials are united with the so formed at least one thread.

9. The process as defined in claim 8, wherein two threads are formed from the fiber materials, fed from the rotary organ and from the spool, which threads are united to form mixed threads, further comprising the steps of regulating the tension of the united threads while passing through the feed zone, fixing the twist applied to the united threads by said heating step, and cooling the united threads between the feed and the texturing zones so as to strengthen their intermolecular structure.

10. The process as defined in claim 9, further comprising the step of bringing the fixed capillary fibers of the united threads into a diffuse state by the application of a fluid medium, such as in an adaptor provided in the texturing zone.
