The present invention; Owing in making the cotton yarn, added cotton grain; Then cotton grain is with long-staple cotton, when medium staple cotton carries out blending, and cotton grain will be wrapped in the cotton thread of finished product and form cotton balls, then adopts the outer surface of the cotton thread that production method of the present invention makes to form with regard to face and has spherical cotton thread.
The specific embodiment
The cotton grain of cotton of the present invention yarn adopts 40% long-staple cotton fiber, 50% medium staple cotton fiber, and 10% cotton grain fiber is processed.
Wherein, said long-staple cotton fiber is meant that hand pulling length is 36-39 centimetre, and cotton grain is less than 90 cotton knots of every gram, and mic value is 3.7-4.2 microgram per square inch, and maturity is greater than 95%, and short fiber content is less than 6%.
Wherein, said medium staple cotton fiber is meant that hand pulling length is that 27-31 centimetre, the every gram of cotton grain are less than 150 cotton knots, and mic value is 3.6-4.2 microgram per square inch, and maturity is greater than 9%, and short fiber content is less than 10%.
Wherein, the cotton grain diameter of said cotton grain fiber is 2 to 4 millimeters, for example 3 millimeters.
Long-staple cotton is in order to increase the brute force of yarn, adopts the mic value of 3.7-4.2 microgram per square inch and greater than 95% maturity fiber, can strengthen the quality of yarn.
The production method of the cotton grain of a kind of cotton yarn may further comprise the steps successively:
Step 1, cotton cleaning process, the long-staple cotton fiber with 40%, 50% medium staple cotton fiber, 10% cotton grain fiber evenly mixes; The ratio of cotton grain fiber is in order to make cotton grain fully be blended in long long-staple cotton fiber and medium staple cotton fiber, to form cotton balls less than long-staple cotton fiber and medium staple cotton fiber.
Step 2, carding step adopts carding machine; Carding machine adopts eight hopper machine mixed cotton, breezes up, in case the cotton grain fiber of halting in rapid 1 drops; Its parameter setting is following: licker-in speed 780rpm/min, and cylinder speed 42rpm/min, removable cover speed is 170rpm/min; It is 40/1000,40/1000,40/1000 inch that doffer speed 850rpm/min, 150 meters of comb and parallel cotton fibers prior to spinning speed per minutes, cover plate space; Wherein, rpm/min is a speed unit, and implication is: what change per minute.Licker-in speed is 780rpm/min, is the gear at a slow speed of carding machine, is in order to reduce cycle, to reduce the broken quantity of cotton grain.
Step 3, mixing in doubling step adopts two road drawing processes; Head and 7 card sliver feedings, drawing frame is adopted in two and 6 sliver feedings; Its parameter setting is following: first drawing-off is set at minimum multiple, and the horn mouth diameter width is 4.2 millimeters, and roller gauge is 42 * 40 * 46 meters; Parameter setting in this step 3 can make Yarn constituent and bar is dried mixes, thereby improves the finished product quality of yarn.
Step 4, the rove operation adopts Speed frames, and its parameter setting is following: first drawing-off is adopted 1.3 times, and speed is changeed for per minute 1000-1300, and roller gauge is 41.5 * 54.5 * * 62.5 millimeters, roving twist 1.19 sth. made by twisting/inches; The parameter setting that this step 4 is mainly is the drafting force and the twist that increases the strip that forms behind the drafting.
Step 5, spinning process adopts fine spining machine, and its parameter setting is following: spun yarn spaces 44 millimeters/48 millimeters, and speed is changeed for per minute 10000-13000, and first drawing-off is arranged on 1.2 times, and hardness is 70 ° roller; The twist is provided with 21 sth. made by twisting/inches, increases the brute force of yarn; Adopt 1#/0 steel traveler, reduce cotton grain and drop.
Step 6, the bobbin operation adopts automatic winder, and its parameter setting is following: speed is decided to be 800rpm/min, and bobbin weight is decided to be 1.89 kilograms/, and fixed length is 6400 meters.This step 5 mainly is that the finished product yarn is carried out the spool assembling.
The present invention; Owing in making the cotton yarn, added cotton grain; Then cotton grain is with long-staple cotton, when medium staple cotton carries out blending, and cotton grain will be wrapped in the cotton thread of finished product and form cotton balls, then adopts the outer surface of the cotton thread that production method of the present invention makes to form with regard to face and has spherical cotton thread.
When the cotton thread making lining that adopts the present invention to make reaches the dress ornament of being made by lining; The sphere on lining and dress ornament surface is that having spherical is that cotton thread itself is with; But not in the smooth formation of on lining or dress ornament, reeling off raw silk from cocoons; Therefore, its intensity can not reduce, and reaches the quality by the dress ornament of lining making thereby improved lining.
The present invention makes finished product test index such as the following table that fineness is the cotton yarn of the dribbling shape that props up of 30 English:
