Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. The examples, in which specific conditions are not specified, were conducted under conventional conditions or conditions recommended by the manufacturer. The reagents or instruments used are not indicated by the manufacturer, and are all conventional products available commercially.

The following will specifically explain the non-pile and its impurity removing method and non-pile product provided in the present application.

Currently, the methods commonly used for dehairing often have the following disadvantages: when the coarse content reaches the standard, the impurity content can not reach the standard, and in order to make the impurity content reach the standard, the carding times are greatly increased, so that the production efficiency is reduced; considering only the production efficiency, the impurity removal effect may not be sufficient.

To improve the above situation, the inventors have improved the carding process, for example: firstly, the cover plate flowers are treated independently, the method has the impurity removal effect to a certain extent, the quantity of the cover plate flowers which meet the requirements of light-color product velvet in whole batch is small, the cover plate flowers contain large impurities, grease is large, the length is short, the difficulty in independent carding is large, and the method is not beneficial to non-wool extraction and integral production. Secondly, increasing the carding times, although the method has certain effect on removing impurities from the lint, the method has the problems of large loss and low generation efficiency; thirdly, the ultrasonic wave is used for washing the down, the method also has a certain effect on removing impurities, but has larger damage to the down fiber.

In view of the above, the inventor creatively proposes to adopt the combing method to carry out lint-free roguing and determines the corresponding combing process conditions through long-term practice and research.

Specifically, the application provides a lint-free impurity removing method, which comprises the following steps: combing the lint to be treated. The combing process is carried out by a combing machine.

Wherein, the technological conditions of combing treatment comprise: the gauge is 17-28mm, the top comb adopts 28-32 gauge needles, the flat brush circular comb is 0 plus or minus 2mm away from the needle tip, the circular brush is 0 plus or minus 1.5mm away from the circular comb, and the feeding amount of the hair hopper is 60-120 g.

The gauge may, by reference, be 17mm, 18mm, 19mm, 20mm, 21mm, 22mm, 23mm, 24mm, 25mm, 26mm, 27mm or 28mm etc., and may also be any other value in the range of 17-28 mm. When the gauge is less than 17mm, the drafting efficiency is easily weakened, and the thick and thin parts are formed; when the gauge is larger than 28mm, the evenness is easily deteriorated.

In this application, the top comb principle in the combing process includes: during the separation and jointing process, the top comb is inserted into the hair cluster, the part of the fiber cluster held by the jaw of the separation roller advances at the surface speed of the separation roller, the tail end of the fiber cluster is dragged from the space between the top comb needles to be carded by the top comb, longer fibers are drawn through the top comb, and substances such as short fibers, impurities and the like which are not separated are blocked in the hair cluster after the top comb. At the end of the separation and connection stage, the nipper starts to swing backwards to leave the separation roller, at the moment, the top comb also swings backwards, so that most of the residual fibers in the fiber cluster are separated from the cotton net clamped by the separation jaw, the nipper continuously swings backwards, the upper nipper closes and closes towards the lower nipper, the upper nipper pushes the small fiber roll which is not carded, and the fiber impurities such as connecting knots, impurities and the like accumulated on the top comb downwards separate from the top comb, so that the fiber impurities are removed.

The top comb may use 28 gauge, 30 gauge or 32 gauge needles. The needles with the number are beneficial to improving the carding degree and the separation degree of the top comb and improving the short fiber removal rate.

The distance between the flat brush circular comb and the needle point can be-2 mm, -1.5mm, -1mm, -0.5mm, 0mm, 0.5mm, 1mm, 1.5mm or 2mm, etc. The distance corresponds to the high-low spacing distance of the top comb, when the distance between the circular comb of the flat hairbrush and the needle point is larger, the top comb is inserted into a flock cluster deeper, the more tiny short flocks, impurities and defects are removed, the better the carding effect is, but the combing flock falling rate is increased; when the distance between the flat brush circular comb and the needle tip is too large, the raising of the pile tufts at the beginning of separation and combination can be influenced.

The distance between the round hairbrush and the round comb can be-1.5 mm, -1mm, -0.5mm, 0mm, 0.5mm, 1mm or 1.5mm, etc. The distance corresponds to the distance between the top comb and the top comb, and when the distance between the round hairbrush and the round comb is smaller, the distance between the top comb needles and the pile tufts to the separating roller is shorter, so that the separation and the bonding work are more facilitated, and the short piles and the sundries are more removed; however, the distance between the round brush and the round comb is too small, which easily causes the collision between the card wire and the surface of the separation roller.

The top feed amount can be 60g, 80g, 100g or 120g, and can be any other value within the range of 60-120 g. The feed rate influences the carding result, the evenness and the yield of the combed sliver. The feeding amount of the hopper can obtain better carding effect and the uniformity of combed wool tops while having higher yield.

The lint-free drop rate after the combing treatment satisfies the following conditions: when the length of the lint to be processed is more than 20mm and less than or equal to 25mm, the shedding rate after combing processing is less than or equal to 50 percent; when the length of the lint to be treated is more than 25mm and less than or equal to 29mm, the shedding rate after combing treatment is less than or equal to 30 percent; when the length of the lint to be processed is more than 29mm and less than or equal to 34mm, the shedding rate after combing processing is less than or equal to 15 percent; when the length of the lint to be processed is more than 34mm, the short-fall rate after combing processing is less than or equal to 10 percent.

On the basis, by controlling the combing process parameters, the method is not only beneficial to removing impurities, bran and the like in the non-plush and improving the production efficiency, but also can increase the non-plush length and reduce the short floss rate.

In an alternative embodiment, before combing, the method can further comprise the step of combining the lint to be treated. The pile combining treatment can be carried out by sucking the non-pile into the pile combining machine through a fan.

Specifically, the pile-combining treatment may mix the lint free to be treated with water, a wool oil and an antistatic agent. Wherein, the water is mainly used for providing the humidity required by cashmere moisture regain; the wool top oil can be used for increasing the oil content and facilitating later-stage spinning, and can increase the strength of single fibers; the antistatic agent is mainly used for preventing static electricity from being generated in cashmere.

In some preferred embodiments, water is present in an amount of 1 to 10 wt% of the non-pile, such as 1 wt%, 2 wt%, 5 wt%, 8 wt%, or 10 wt%, and the like, and can be any other value within the range of 1 to 10 wt%. The amount of the hair oil is 2.5-8.5 wt%, such as 2.5 wt%, 3 wt%, 4 wt%, 5 wt%, 6 wt%, 7 wt%, 8 wt% or 8.5 wt%, and may be any value within 2.5-8.5 wt%. The antistatic agent is used in an amount of 1-6 wt%, such as 1 wt%, 2 wt%, 3 wt%, 4 wt%, 5 wt%, or 6 wt%, or any other value within the range of 1-6 wt%.

Furthermore, a stewing treatment is also included between the pile combining treatment and the combing treatment.

The soaking treatment may be carried out at 30-35 deg.C for 8-12h (such as 8h, 9h, 10h, 11h or 12 h).

By stewing under the above conditions, the non-plush whole body can be uniformly remoistened, and the remoistening index is about 20-24%.

Further, a sliver making process is also included between the stewing process and the combing process. Specifically, the non-plush is fed into a carding machine for strip making, and the strip barrel is replaced into an empty strip barrel after being nearly fully loaded so as to continuously accumulate and make the non-plush. The weight of the strip after strip making is about 5-7 g/m.

And (3) the sliver making process is a combing process, after combing is finished, quality detection is carried out on finished products of the combing machine, and after the detection indexes are qualified, finished products are packaged (for example, the finished products can be arranged into a standard package of 30 kg).

Accordingly, the present application also provides a non-pile produced by the pile removing method, and the resulting non-pile. Compared with the non-plush (understood as combed material before treatment) to be treated, the non-plush (understood as combed material after treatment) obtained by the method has the impurity content reduced by about 65 percent, and the combed products all meet the light-color product down requirement (below 60 per gram); the non-plush length after combing is increased by about 5.9mm compared with the feeding material, the short floss rate can be reduced by about 8.27 percent on average, and the non-plush fineness after combing is increased by about 0.72 mu m compared with the feeding material.

In addition, the application also provides a non-plush product, the manufacturing raw materials of the non-plush product comprise the non-plush, and the non-plush product is high in quality.
