A process for producing a double-faced woolen fabric, the process comprising the steps of spinning, weaving and post-finishing, wherein the post-finishing comprises, in sequence, the steps of washing a woolen fabric, fulling the woolen fabric, a first instance of drying and shaping the woolen fabric, dissolving connecting threads with hot water, and a second instance of drying and shaping same. The connecting threads for double-layer weaves of the double-faced woolen fabric are polyvinyl acetal fiber yarns, and the fiber compositions of the double-layer weaves both comprise wool fibers; the process temperatures for the steps of washing and fulling the woolen fabric are lower than an initial dissolution temperature for the polyvinyl acetal fiber yarns; and an acting force causing wool felt shrinkage is applied to the double-faced woolen fabric while the connecting threads are dissolved. In the production process, the double-faced woolen fabric is finished into a connecting-thread-free double-layer structure, and during a sewing process of the double-faced woolen fabric, an edge of a cut piece can be directly picked up by using a sewing needle, thereby completely avoiding defects and loss generated during an edge cutting operation, and improving the sewing efficiency and fabric utilization rate.

PREPARATION METHOD FOR HEATING WARM-KEEPING WOOL FABRIC
Disclosed is a preparation method for a heating warm-keeping wool fabric. The method comprises: dying wool in a fabric by using an environment-friendly reactive dye for wool, dying a Thermolite fiber by using a disperse dye, dying Tencel by using a reactive dye for cotton, and not dying an EKS heating fiber; selecting a semi-combing device for spinning; performing warping by using a warping machine; performing open-width washing and scouring combination after warping, and then performing drying; performing sucking and impacting in a dry state after drying; performing open-width washing and scouring again after singeing, and then performing drying; performing intermediate inspection for finishing after drying; and finally performing steam blowing. The high moisture regain and high moisture absorption of the Tencel fiber and good thermal insulation of the Thermolite fiber are used to perform blending with wool and the EKS fiber to produce a synergistic effect, so that the moisture absorption, heating and warm-keeping performances of the fabric are enhanced, the high-performance heating warm-keeping fabric is developed, the maximum temperature rise of the fabric is greater than or equal to 8.0°C, the average temperature rise value within 30 min is greater than or equal to 3.5°C, Clo value is greater than or equal to 0.3, and air permeability is greater than or equal to 150 mm/s.

METHOD FOR PRODUCING COLORED SEMI-WORSTED WOOL/ACRYLIC FIBER BLEND SIROSPUN YARN
A method for producing colored semi-worsted wool/acrylic fiber blend sirospun yarn. The method comprises: using a worsted-wool spinning machine to perform siro spinning on two semi-worsted wool/acrylic fiber blend rovings of different colors to produce a finished colored wool/acrylic fiber blend sirospun yarn product; mounting an auxiliary spinning device on a machine frame (14) between a yarn output point of a front roller (11) and an upper leather rod (12) and a yarn guiding hook (13) of the worsted-wool spinning machine; and in a spinning process, controlling, by using a pair of yarn guiding rods (4) of the auxiliary spinning device, the position of a twisting point of the two blended rovings relative to a twisting triangular region (16) , and adjusting the shape of a siro spinning triangular region so as to change the number of fibers of each of two colors distributed on a surface of finished yarn, such that the color effect of the yarn surface is changed, and corresponding colored sirospun yarn is produced. The advantage of the method is as follows: a worsted-wool spinning machine does not need to be modified, and the yarn surface of colored sirospun yarn produced on the worsted-wool spinning machine has a large adjustment range of the distribution ratio of two types of fibers and a more obvious color change effect.
A method for producing a formaldehyde-free easy-care shirt, comprising the following production steps in sequence: shirt sewing, washing, drying, spraying of a formaldehyde-free easy-care finishing liquid, pre-drying, pre-ironing, pressing, baking, freezing, washing of a finished product, drying of the finished product, and packing of the finished product. By spraying the formaldehyde-free easy-care finishing liquid, a pick-up of the skirt reaches 65-90%; the formaldehyde-free easy-care finishing liquid consists of the following components: easy-care resin, a fiber protective agent, a softening agent, a catalyst, and water; the temperature of the pre-drying is 40-60°C, and the pick-up of the pre-dried skirt reaches 20-50%; the temperature of the baking is 140-160°C and the duration is 3-7 minutes; the temperature of the freezing is -10°C to 0°C, the freezing duration is 0.5-1.5 hours, and the humidity of a freezing chamber is 60-90%. By means of the method, no formaldehyde is generated in the entire skirt production process, and the finished easy-care skirt product thus contains no formaldehyde residue.
