The word "embodiment" as used herein, is not necessarily to be construed as preferred or advantageous over other embodiments, including any embodiment illustrated as "exemplary". Performance index tests in the examples of this application, unless otherwise indicated, were performed using routine experimentation in the art. It is to be understood that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the disclosure.
Unless defined otherwise, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; other test methods and techniques not specifically mentioned in the present application are those commonly employed by those of ordinary skill in the art.
The terms "substantially" and "about" are used herein to describe small fluctuations. For example, they may mean less than or equal to ± 5%, such as less than or equal to ± 2%, such as less than or equal to ± 1%, such as less than or equal to ± 0.5%, such as less than or equal to ± 0.2%, such as less than or equal to ± 0.1%, such as less than or equal to ± 0.05%. Numerical data represented or presented herein in a range format is used merely for convenience and brevity and thus should be interpreted flexibly to include not only the numerical values explicitly recited as the limits of the range, but also to include all the individual numerical values or sub-ranges encompassed within that range as if each numerical value and sub-range is explicitly recited. For example, a numerical range of "1 to 5%" should be interpreted to include not only the explicitly recited values of 1% to 5%, but also include individual values and sub-ranges within the indicated range. Thus, included in this numerical range are individual values, such as 2%, 3.5%, and 4%, and sub-ranges, such as 1% to 3%, 2% to 4%, and 3% to 5%, etc. This principle applies equally to ranges reciting only one numerical value. Moreover, such an interpretation applies regardless of the breadth of the range or the characteristics being described. The twist direction mentioned herein refers to the twist direction of the fiber or strand, and is generally divided into Z twist direction and S twist direction, which are opposite, for example, the opposite twist direction of the fiber means that one twist direction is Z twist direction and the other twist direction is S twist direction; the same fiber twisting direction means that the two twisting directions are the same Z twisting direction or the same S twisting direction. The fiber wool mentioned herein means that the fiber monofilament constituting the monofilament twisted thread is broken to form a free end, the free section of the fiber monofilament is extended out from the surface of the fiber monofilament, the formed fiber with one free end and the other end bound on the monofilament twisted thread is usually only broken by part of the fiber monofilament distributed on the surface layer of the monofilament twisted thread, and the broken parts are distributed at intervals along the axial direction of the monofilament twisted thread and are uniformly arranged, and the formed fiber wool is distributed at intervals along the axial direction of the monofilament twisted thread and is uniformly arranged. The downstream end referred to herein is generally in terms of the direction of movement during the raising of the broken filament yarn, e.g., the positioning of the breaking assembly at the downstream end of the dividing assembly generally means that the filament yarn passes through the dividing assembly first, then the breaking assembly, and so on, and the breaking assembly is positioned at the upstream end of the carding assembly, generally means that the filament yarn passes through the breaking assembly first, then the carding assembly.
