Embodiment 1

[0015] vertical Density: 120 threads / inch, yarn count: 40 British count single yarn, composition: cotton 70%, wool 30% Latitude Density: 90 threads / inch, yarn count: 40 British count single yarn, composition: cotton 70%, wool 30% organizational structure 2 / 2 broken oblique color Blue Gray Black Multicolor Plaid

[0016] The specific steps are:

[0017] The production process is spinning → dyeing → sizing → weaving → singeing → desizing → liquid ammonia → pre-stenter → sanding → sanding → tenter → pre-shrinking. Among them, the singeing speed is 95m / min, the singeing method adopts cutting and burning, and the flame intensity is 10 mbar; the liquid ammonia speed is 30m / min; the sanding speed is 15m / min, the large cylinder speed is 20r / min, and the tension is 200N; In the pre-stenter process, the concentration of the fatty acid softener RQR in the roll groove is 15g / L, and the pre-stenter temperature is 120°C; The concentration of RQR is 10g / L...

Abstract

The invention provides a production process of cotton-wool-blended yarn-dyed fabric. The production process is characterized in that warps and wefts are cotton-wool-blended 40-count single yarn, 50-count single yarn or 60-count single yarn, the blending ratio is 75-85% of cotton and 30-15% of wool, fabric weave is 3 / 1 twill weave, 2 / 1 twill weave, 2 / 2 twill weave or 2 / 2 broken twill weave, warp density is 120-150 / inch, and weft density is 80-110 / inch. The production process sequentially includes: spinning; dyeing; sizing; weaving; singeing; desizing; performing liquid ammonia finishing; pre-tentering; sanding; sanding; tentering; preshrinking. The high-end cotton-wool-blended yarn-dyed fabric woven by the production process has the features of moisture absorption, breathability and soft touch of cotton fibers, keeps the properties of excellent elasticity, soft touch and warm keeping of wool fibers, is light and thin in texture, soft in touch and good in warm-keeping performance and hasexcellent washability and certain wrinkle resistance.

Description

technical field [0001] The invention relates to a production process of a cotton-wool blended yarn-dyed fabric, belonging to the technical field of textiles.
