In the above technical solution, in the value range represented by the symbol "-", when the lower limit end point is 0, the end point value is not included; when the lower endpoint is not 0, the endpoint value is included.

In the technical scheme, the percentage is mass percent.

The basic principle of the invention is as follows:

the high-proportion worsted velvet product of the invention has four technical problems:

1. silk particle: the problem that the wool particles are comprehensively considered from three aspects of card clothing, gauge and speed ratio, and small gauge and strong carding are required is solved;

2. the static electricity in the manufacturing process is serious: the static problem is solved by starting from the wool combining process and strictly controlling the temperature and the humidity of a workshop in the production process;

3. the characteristics of the two fibers create a contradiction in the processing technology: in the velvet processing process, the silk has high strength, is easy to be agglomerated into silk grains, needs strong carding, has low strength and is easy to be broken into ultra-short fibers. When the velours are combed together, a balance point needs to be mastered, namely, the velours do not need to be combed excessively and strongly on the premise of not generating hair grains; before the combined wool carding, the dyed yarns should be opened, so that the carding state can be improved;

4. and (3) velvet falling: the twist degree plays a great role in improving fluff falling, the twist coefficient is too high, the fabric is hard, the twist coefficient is too low, and the fabric is easy to fall fluff.

The principle of producing high-proportion velvet products is to select a more optimal production route flow and the like by improving the quality of raw materials, improving the wool-added wool oil and the antistatic agent. Therefore, the product has less wool particles and small static electricity in the production process, so that a velvet product with higher proportion can be spun.

Therefore, there are several key steps in the selection of the process route:

the first step is to reasonably select raw materials. Because spun silk is thin and is easy to be tangled and conglobated in the spinning process, the spun silk with proper fineness, softness, smoothness and good hygroscopicity is selected to ensure that the spun silk has better strength, elasticity and luster.

The cashmere matched with spun silk has high short staple rate due to large length dispersion of cashmere fibers during material selection, the short staple rate is easy to generate hair particles in the carding process, the short staple rate is generally controlled within 8 percent, and the short staple rate is controlled within 5 percent during high count yarn spinning.

The second step is the quality control in the dyeing step, and in order to reduce the carding load of the carding machine and enhance the carding effect, the loose and smooth state of the fibers should be kept as much as possible. Before dyeing, the spun silk needs to be opened by an opener so as to ensure that felt is formed after dyeing of the dyed spun silk after the colloid content of the dyed spun silk is increased, and the subsequent processing and the yarn quality are influenced. Naturally, degumming of spun silk by dyeing is also thorough, hardening, hard lumps and the like which are formed because of incomplete degumming are avoided, but excessive degumming is also avoided, so that the surface of the spun silk is rough and has burrs, small hair grains are easily formed in the spinning process, and the small hair grains are very obvious in color and luster.

In the dyeing process, pretreatment and aftertreatment are enhanced, wherein the pretreatment is to thoroughly remove dirt and impurities in raw materials, the dyed color is pure and bright, the fiber state is soft, smooth and loose, the aftertreatment is to re-wash the dyed silk clean, has no floating color and is not sticky, and the color fastness and the smoothness of a spinning link are ensured. In addition, compared with spun silk, cashmere is loose and smooth in fiber, easy to comb and low in probability of generating wool particles, so that in general, the spun silk is used as a main color, the cashmere is used as a color matching, the wool particles are good in visual performance, such as 75/25 velvet, deep flower ash, black and white 2 colors, the proportion of black is high, the silk can be dyed into black, and white color matching is left on the cashmere.

And thirdly, optimizing a blending process. Wool oil is required to be added into the spun silk and the cashmere respectively, the cashmere is generally controlled to be about 2%, the cashmere fibers are mutually adhered due to excessive wool oil, and due effects cannot be achieved due to insufficient wool oil. The silk static electricity is big, should add about 2 ~ 3% electrostatic agent to with opener opening, stifle storehouse 24 hours, the loose degree of various fibre in the raw materials is unanimous basically, the dyeing fibre should be opened in advance, to the big variety of shade phase proportion difference, need adopt the mode of falsely closing, make the raw materials intensive mixing, need strictly control the degree of consistency of adding the oil water, guarantee stifle storehouse time.

And fourthly, optimizing a spinning process route. Adopts a process route combining cotton spinning and wool spinning equipment. The speed ratio between the cylinder and the doffer and between the cylinder and the needle roller is reasonably selected once through a cotton spinning carding machine, a process route with tight spacing and strong carding is adopted between a cover plate of the carding machine and the cylinder, the carding capacity is improved, fiber entanglement is reduced, the fibers are fully carded and form a single fiber state, the ration of carding is slightly controlled, generally within the range of 13-15 g/5 m, the carding effect of the carding machine is facilitated, the drafting multiple of a later process is reduced, and the evenness is improved. And in the needle combing process, a needle is added with water according to the ratio of 1: 12, the spraying is mainly uniform, meanwhile, the smoothness of a yarn channel is kept, the fibers are prevented from being tangled, the temperature and the humidity of a workshop are properly controlled, the fibers are prevented from generating electrostatic aggregation, and the continuous generation of wool particles is reduced. Combing, namely combing two sides, oiling the four needles of the compound comb according to the proportion of 1: 12 after oiling, and standing for 24 hours after oiling to ensure that oil and water are fully absorbed.

Compared with the prior art, the invention has the beneficial effects that:

(1) according to the invention, through improving the quality of raw materials, improving the wool oil and the antistatic agent added by wool and selecting a better production route flow, the product has less wool particles and small static electricity in the production process, and a velvet product with higher proportion is finally spun;

(2) the invention develops two new products with different hand feelings from different proportions:

firstly, the method comprises the following steps: 85% silk 15% wool product;

secondly, the method comprises the following steps: 70% silk 30% velvet product.
