Embodiment 1

[0023] Example 1, preparation of polyamide / hemp viscose fiber composite textured filament yarn

[0024] (1) Pre-oriented polyamide filaments with a specification of 75dtex / 50f are prepared according to the conventional polyamide spinning process.

[0025] (2) Two bundles of 75dtex / 50f polyamide filament pre-oriented yarns prepared by step (1) are fed into 1# drafting roller group and 2# drafting roller group respectively to carry out heating and drawing treatment, and prepared different thermal Polyamide drawn yarns A and B of shrinkage. Among them, the drafting ratio of the 1# drafting roller group is 1.59, and the temperature of the drafting hot roller is 150°C; the drafting ratio of the 2# drafting roller group is 1.350, and the temperature of the drafting hot roller is 90°C. The heat shrinkage rate of the prepared polyamide drawn yarn A was 5.1%, and the heat shrinkage rate of the polyamide drawn yarn B was 16.2%.

Abstract

The invention discloses a cellulose fiber / synthetic fiber sheath core type composite modified continuous filament yarn and a preparation method thereof. A core layer of the composite modified continuous filament yarn is made of cellulose fibers, a sheath layer of the composite modified continuous filament yarn is made of synthetic filament fibers, interfaces of the core layer and the sheath layer are formed by mutually winding the cellulose fibers with the synthetic filament fibers, and the synthetic filament fibers in the middle of the sheath layer form a filament circle on the surface of the composite modified continuous filament yarn. The preparation method includes: firstly, subjecting the synthetic fiber raw materials to melt spinning to prepare pre-oriented yarns; secondly, drafting the synthetic fiber pre-oriented yarns and using a hot roll to shape the synthetic fiber pre-oriented yarns to obtain two types of synthetic fiber filaments which are different in tensile property and heat shrinkage; and thirdly, using pairwise rollers to control the two types of the synthetic fiber filaments and the cellulose fiber filaments, feeding the synthetic fiber filaments and the cellulose fiber filaments into an air jet texturing device with double air passages according to a certain over-feeding rule for texturing, using a heating box for heating, and winding for forming so that the cellulose fiber / synthetic fiber sheath core type composite modified continuous filament yarn is prepared.

Description

technical field [0001] The invention relates to a cellulose fiber / synthetic fiber sheath-core composite deformed filament yarn and a preparation method thereof. Background technique [0002] Different fiber materials exhibit different physical properties due to their different components. Blending of different fibers to prepare blended fabrics can learn from each other and make use of the performance advantages of various fibers to make up for the lack of performance caused by another fiber, so as to obtain fabrics with good comprehensive properties. At present, textile enterprises develop and produce various blended fabric products to meet the various needs of the market. However, the performance of the blended fibers is not only related to the fiber species, but also related to the structure distribution state formed by the various fibers in the blended yarn. The preparation method of the blended yarn comprises: (1) blending and spinning different types of short fibers i...
