Embodiment 1

[0026] The wool fibers were pretreated in a 3wt% sodium bisulfite treatment solution at 75°C to open the disulfide bonds and salt bonds between the helical macromolecules, and then stretched on a stretching machine with a twist of 30 twists / m , the stretching speed is 50% / min, the stretching ratio is 40%, and the tops after stretching and setting are subjected to setting treatment in 6.5% potassium persulfate and 1.5% zinc acetate solution. The obtained 40% stretched wool yarn is then interwoven into a fabric on a loom according to a one-upper-down plain weave. The warp and weft densities of the fabric are 350 / 10cm and 280 / 10cm respectively, and then the fabric is dyed at 115°C, the fabric will obtain a shrinkage rate of 10%, and the structure will become tight and elastic.

Embodiment 2

[0028] The wool fiber was pretreated in a 5wt% sodium bisulfite treatment solution at 70°C to open the disulfide bonds and salt bonds between the helical macromolecules, and then stretched on a stretching machine with a twist of 15 twists / m , the stretching speed is 30% / min, the stretching ratio is 90%, and the tops after stretching and shaping are subjected to setting treatment in 5.5% potassium persulfate and 2.5% zinc acetate solution. Then, the obtained wool yarn with 60% elongation rate is interwoven into a fabric on a loom according to a plain weave one above the other. The warp and weft densities of the fabric were 350 / 10cm and 280 / 10cm respectively, and then the fabric was dyed at 110°C, the fabric obtained a shrinkage rate of 15%, and the structure became tight and elastic.

Embodiment 3

[0030] The wool fibers were pretreated in a 3wt% sodium bisulfite treatment solution at 75°C to open the disulfide bonds and salt bonds between the helical macromolecules, and then stretched on a stretching machine with a twist of 30 twists / m , the stretching speed is 50% / min, the stretching rate is 20%, and the tops after stretching and setting are subjected to setting treatment in 6.5% potassium persulfate and 1.5% zinc acetate solution. Then, the obtained wool yarn with a stretch ratio of 20% is interwoven into a fabric on a loom according to a plain weave one above the other. The warp and weft densities of the fabric were 350 / 10cm and 280 / 10cm respectively, and then the fabric was dyed at 105°C, the fabric obtained a shrinkage rate of 5%, and the structure became tight and elastic.

Abstract

The invention discloses soft wool fabric of fine elastic wool based on beta folding to alpha spiral transition and preparation thereof. The preparation method includes the steps that: wool is made towool tops with drawing-down fibers through pretreatment, stretching, and once forming, then the wool tops are processed into wool yarn through spinning, or the wool tops are directly made to the woolyarn with drawing-down fibers through the pretreatment, the stretching, and the once forming, the wool yarn is made to fabric through warp-weft interweaving, and then the fabric is subjected to rebound forming treatment based on beta folding to alpha spiral transition to obtain the fine elastic wool fabric. The fine wool fabric is applied for outdoor sportswear clothing so that the fabric protective effect is strengthened.

Description

technical field [0001] The invention relates to a research method for the thinning mechanism of wool fibers, in particular to a fine elastic wool fabric based on the conversion of β-fold to α-helix wool yarn and its preparation. Background technique [0002] Wool is an important textile raw material. It has the characteristics of good elasticity, good heat retention, strong hygroscopicity, not easy to stain, and soft luster. Wool is a material for various high-end clothing and precious decorations, and is also widely used in thermal insulation. Strong seasonal fabric. In recent years, with the improvement of people's requirements for the quality of life, wool fabrics with both warmth retention and lightness have become more and more favored by consumers. Therefore, the lightening of wool fabrics has become an important research direction. Chemical reduction of fineness is a scientific and effective solution. Existing wool thinning materials generally have a shrinkage rate ...
