The invention discloses a moisture-absorbing and heating alkali-free mercerized fabric and a processing method of the same. The fabric has cotton on the front and moisture-absorbing and heating Heatwarm fibers on the back, and a heat insulation air layer is arranged between the front and the back of the fabric. The processing method includes the steps as follows: every two knitting needles are arranged at the top and the bottom of a two-faced machine for knitting, and linters are arranged with needles opposite to each other; during the knitting, every eight paths form a circulation, 1st and 5th paths penetrate the Heatwarm to be connected in a way that two sides are engaged, the upper and lower high-channel stitches of the 1st path are double stitched in a way that two sides are engaged and the upper and lower low-channel stitches of the 5th path are double stitched in a way that two sides are engaged, so as to knit an intermediate connecting layer; 2nd and 6th paths penetrate cotton yarns to be connected in a way that one side is engaged, and upper stitches are all looped to be knitted out of an outer layer; 3rd, 4th, 7th, 8th paths penetrate the Heatwarm to be connected in a way that one side is engaged, the lower stitch low-channel stitches of the 3rd path are double stitched and the high-channel stitches are looped, the lower stitches of the 4th and 8th paths are all looped, the lower stitch low-channel stitches of the 7th path are looped and the high-channel stitches thereof are doubled stitched, so as to be knitted out of an inner layer. The fabric has soft and smooth handfeel and silky luster after the DGF treatment through the alkali-free mercerizing finishing agent, and has the effect of moisture absorption, heating, thermal insulation and air permeability.

The invention discloses an antibacterial woolen sweater. The woolen sweater is made of yarn formed by blending fabrics of wool, cashmere, shengma Shengma fibers, modal fibers and nylon. The woolen sweater comprises components in percentage by weight as follows: 25%-35% of the wool, 5%-15% of the cashmere, 8%-20% of the shengma Shengma fibers, 15%-25% of the modal fibers and the balance of the nylon. The woolen sweater is formed by blending of the raw materials according to a special proportion, highlights characteristics of each type of fibers of the raw materials, integrates advantages of all raw materials, has the antibacterial function, and simultaneously has the advantages of good hand feeling, high grade, high heat retention property, low cost and the like.

The invention discloses a device and a method for extracting sticky down by deeply processing down. The device for extracting the sticky down by deeply processing the down comprises a feather yarn separation box (1), a neck feather yarn separation box (2) and a down flying yarn separation sieve (3) which are connected in turn. The method comprises the following steps of: 1) disinfecting, sterilizing and deodorizing feathers by using a high temperature of 120 DEG C generated by water vapor and pressurizing to make the feathers separated to form the down; 2) putting the down into the feather yarn separation box through a feeding hole for processing to separate feather yarns; 3) putting the down in a sieve barrel into the neck feather yarn separation box through a discharging opening for processing to separate neck feather yarns; and 4) putting the down in an inner box body into the down flying yarn separation sieve for processing to separate down flying yarns. By the device and the method, the feather yarns, the neck feather yarns and the down flying yarns can be efficiently separated to extract the sticky down with the down content of 97 percent.

The invention relates to a multifunctional down jacket, which comprises a main body and a liner which is detachably arranged in the main body, wherein the main body is made from a woolen material; and silks, hollow cotton fibers, duck downs or velvets are filled in the liner. The down jacket disclosed by the invention, besides the functions as a down jacket, can also detach a jacket body and the liner for separated use; therefore, the down jacket is diverse in function and stronger in practicability.
