Control Mao Yu how effectively, be platitude talk endowment, it is the serious problem in spinning experience, mao Yu affects the exterior of yarn to follow feel not merely, and be in weaving experience, make very easily between photograph adjacent yarn mutual and intricate and cause a mouth not clear, very person can cause end broken end, reduce labor productivity.

Method one

Adopt gather spinning technique

Gauze roll twist twisting triangle division is formed when gauze, move of fiber inside and outside is smart, fiber head end is squeezed to give gauze bodily form to become Mao Yu easily, adopt gather spinning technology to be able to reduce Mao Yu effectively.

Technology of alleged gather spinning uses the rally in colonies area namely implement (horn mouth) the gauze to implementation draft action undertake colonies, process application of principle of fly frame D draft craft to spun yarn namely, encircle drafting arrangement in traditional 3 Luo Lashuang short skins namely advocate before drafting zone, add again install a pair of Luo La, form division of a gather, gather is adopted inside gather area implement will finish gauze the colonies after draft. The gather in drafting zone of purify original owner implement, optimize advocate group of force of drafting zone attrition distributings will improve gauze a dry quality. Through gauze collect action to reduce gauze twisting triangle area, reduce gauze thereby Mao Yu, reduce fibrous be lost, because the fiber in yarn is more parallel,at the same time unbend promotes gauze thereby puissant wait for index.

Add outfit gather implement hind, no matter be,be in advocate drafting zone or be opposite in colonies area gauze Mao Yu amount has certain control effect. Add held rally implement hind, beard marching particular assemble action all can get before twisting triangle area, need a width by wide narrow, decrescent of twisting triangle area, mao Yu's generation can gain proper control, especially the generation of the long Mao Yu to 3 millimeter above, its control effect is more apparent. Because of colonies implement to gauze control belongs to rigid, inelastic control, control gauze of improper can austere influence a dry uniformity, because this assembles implement exit diameter cannot be designed too smally, colonies action got be restricted certainly consequently, the control of the Mao Yu of 2 millimeter length also can have 1 ~ a few influences. Use up cop got collect action certainly before undertaking twisting, gauze when undertaking twisting, still be compressed and banding, mao Yu's generation must not avoid. But because of twisting triangle area reduce, the rate that fiber inside and outside changes is controlled certainly, long Mao Yu (here advocate if need a brim fiber place by twisting triangle area,form) the amount decreases consequently.

Method 2

Take warping working procedure seriously

The Mao Yu of yarn surface basically arises at spun yarn working procedure, grow at working procedure of canister of subsidiary channels in the human body through which vital energy. The immanent quality that the length of yarn Mao Yu follows parameter of rate of raw material function, plan matching cotton, short fine hair, craft and each working procedure to feed see ban4cheng2pin3 with the amount is direct and relevant, the effect that still suffers environment of facility status, workshop, spinner to operate level of management of level, workshop to wait at the same time. To yarn surface Mao Yu studies from the control proceed of spinning working procedure more, and reduce yarn surface Mao Yu to take seriously however to warping working procedure insufficient.

The warping factor that affects yarn Mao Yu is not little, warping type is in the center one of. The transmission way of machine of traditional 1452A warping is warp beam of platen tendency drive, because jockey when, warp beam is inertial circumgyrate makes warp beam unfinished stops completely turn, warp beam can skid on platen, make yarn surface wears hair easily, mao Yu increases. Be like machine of Benin case warping to new-style warping machine, because adopt hydraulic pressure of drive of alternating current machine pressure regulating the transmission way of warp beam of straight drive of pump and gearshift motor stepless speed regulation, this transmission way can reduce warp beam apply the brake effectively to cause the state with cottony warp to happen. It is warping tension next. In warping because the consideration is even a gauze tension, on warp creel different the tensional gasket weight that derivative yarn place configures the position is different, different also to the influence of yarn Mao Yu. Warping tension increases along with tensional gasket weight and increase, number of wool feather root also increases. Warping speed also can affect the generation of yarn Mao Yu. We with 14.5 gauze of cleanse cotton blending is Tekesi exemple have a test, the result shows as the addition of warping speed wool feather root is counted also continueing to increase. Because speed increases,this is hind, warping tension also is increasing, yarn follows warping machine to go up to guide each the attrition aggravate of gauze component, mao Yu of gauze substance appearance increases. When warping guiding gauze is apart from is to show bobbin coping follows guide the distance between gauze porcelain eye. When warping rate is fixed, inevitable existence some guides gauze is apart from, pulling force is the right now smallest. Via actual test and verify, this distance is in normally 200 millimeter of 180 ~ . What because guide,gauze is apart from is different, warp tension is different also, criterion Mao Yu how many different also.

To certain warping type, can reduce Mao Yu from three angle: The first, tensional configuration is proper, make sure tension is even, circumgyrate component circumgyrate is agile; The 2nd, guide gauze component surface is slick, without crack, damaged, small to yarn attrition; The 3rd, speed suits with tensional gasket configuration.

Method 3

Actor chooses component of canister of subsidiary channels in the human body through which vital energy and technology

Canister of subsidiary channels in the human body through which vital energy is the working procedure with most growth of yarn Mao Yu, after cop passes canister of subsidiary channels in the human body through which vital energy, mao Yu increases 35 % ~ 45 % . Think commonly,

This advocate if be chafed because of yarn by each attrition component the action of force, bring about the fiber with embedded not deep yarn to be smoked to pull out come, form second birth Mao Yu. Below coequal condition, the linear velocity of cone winder is taller, the scope that Mao Yu increases is bigger; Tension of gauze of subsidiary channels in the human body through which vital energy increases along with what yarn counts especially and increase, subsidiary channels in the human body through which vital energy is same when the yarn that counts especially, pulling force of gauze of subsidiary channels in the human body through which vital energy is larger, the Mao Yu of canister gauze increases more; Different material is different the groovy canister that machines quality, its surface condition is different, the scope that Mao Yu increases is different also. Generally speaking, bakelite chamfer canister is compared with metallic chamfer canister, mao Yu can increase 15 % ~ 20 % ; Fit of mechanical clear gauze is right of yarn Mao Yu increase be clearly, and device of electronic type clear gauze can increase Mao Yu scarcely.

The linear velocity of cone winder is unfavorable and exorbitant, the linear velocity of traditional cone winder is controlled commonly in 500 ~ 600 meters of / minute, the linear velocity of automatic winding machine is controlled commonly in 900 ~ 1100 meters of / minute; In make sure tube figuration is good, hind below the state that treatment does not take off a circle, tension of gauze of subsidiary channels in the human body through which vital energy in order to slant small advisable. Continuously cone winder each parts position is good it is the important step that reduces Mao Yu of gauze of subsidiary channels in the human body through which vital energy. In main part, answer to adopt electronic yarn clearer to follow metallic chamfer canister as far as possible, because these components are right the attrition force of yarn is small, reducing yarn Mao Yu while, also can promote the whole of cheese quality. Temperature and humidity of workshop of canister of reasonable control sth resembling a net also is helpful for reducing yarn Mao Yu, be in with relative humidity control commonly control of 75 % left and right sides, temperature is in 30 ℃ less than had better.
