The specific embodiment
The invention will be further described below in conjunction with embodiment.
One, the selection of raw material
On raw material was used, natural fabrics such as half spun yarn product can the processing cotton, suede, hair, fiber crops, silk also can be produced the number of chemical fiber that comprises the new type functional fiber; Not only can do the pure of single component and spin, the blending of applicable again various compositions, different proportion.No matter its made yarn is to be applied on worsted fabric, the slubbing lining, or on being applied to knitting sweater, showing solicitude for, product style is all taken the course of its own.
Half spinning selection: select sheep's wool, Australia's wool top, goat cashmere etc. respectively for use according to the needs of product with hair.
Index request: fineness: 16.5~20 μ m
Contain thick :≤0.3%
Contain assorted :≤0.5%
Short flannel :≤20%
Color and luster: white.
In order to obtain the fiber that the body portion cloth length reaches unanimity, must use fiber and lead disconnected technology, by the different roller drawing-off repeatedly of multiple tracks speed of gyration, that the fiber of wrapped configuration is stretching, under stretching state overcut fibre is led disconnected shortening, staple length remains unchanged.
Two, spin preceding preliminary treatment
When hair is produced, be easy to generate static on cotton spinning apparatus, have a strong impact on spinning process through friction, particularly in comb and parallel cotton fibers prior to spinning, mixing in doubling step.So finish is treated as the crucial one procedure of spinning quality (comprise the finish selection, oil formula is selected, the oil content analysis).
1, finish is selected:
Ludox, a kind of colloidal solution of little blue opalescence has bigger specific area, and stronger adsorptivity can be attached to fiber surface, and no longer water-soluble, thereby plays the effect of fortifying fibre cohesive force.
And crude oil, be mainly used in wool industry and have significant infiltration, wetting and antistatic property, can obviously improve wool fibre and in spinning process, fly hair and broken end phenomenon, can also improve the toughness of cashmere, reduce the damage of fiber in cotton spinning apparatus combing and roller draft process, reduce short fiber content.
Antistatic additive is eliminated the static that wool fibre produces in friction process, improve spinnability.
2, oil formula:
Antistatic additive: 0.3~0.7%,
And crude oil: 0.2~0.8%,
Ludox: 0.1~0.15%.
Described antistatic additive is selected anionic hair antistatic additive for use.
Described and crude oil commodity in use and crude oil are the liquid form products that the self-emulsifying dispersion method is made, add during use water stir slightly emulsion.Be neutral, pH value is between 7~8, in order to avoid damage wool fibre, card clothing and influence dyeing.Viscosity is unsuitable excessive, and generally grace third constellations viscosity is 0.98~2.93 in the time of 50 ℃, otherwise the easily sticking and difficult comb of fiber is opened.Freezing point should be below 10 ℃.
Described Ludox chemical name cataloid, electronegative.
3, oil content analysis
Residual grease adds the content of finish on the wool, not only influences the weight of wool, and road, influence back processing technology, and oil content is too much, can adhere to card clothing during carding, makes the wool-carding processing difficulties; Otherwise yolk content is very few, and frictional force is big in the combing process, easily causes the wool damage and produces static.So whether the finish amount suitable production efficiency of products, product quality and the cost of directly having influence on.
This programme adopts the mass specific resistance test index, for the pre-treatment of spinning of hair provides foundation, by a large amount of tests, draws as drawing a conclusion, and this numerical value is less than 10 8Ω g/cm 2The time, can ordinary production.
Three, Processes and apparatus improves
From the technology of half spinning employing, improving raw material combing link, the key point of type configuration concentrates in the selection of the type selecting of carding machine and hair bucket feeding part.The characteristics of half spinning production are " small lot, many kinds, the low speed of a motor vehicle ", and carding machine is selected the FB201 carding machine of Qingdao Textile Machinery Co., Ltd. for use.
