Abstract
The invention discloses an irregular raindrop yarn production method, relates to the technical field of weaving of knitted fabrics and decorative fabrics, and in particular relates to the technical field of spinning of irregular raindrop yarns. Irregular raindrop yarns are formed by opening and picking cottons, carding the cottons, drawing strips, forming course yarns, forming fine yarns and performing spooling by adopting pure cottons or polyester and cotton mixed raw materials; long fibers are used for performing framework connection and improving the strength of the yarns; and short fibers form style bamboo joints. By the method, bamboo joint yarns of which the bamboo joints are only millimeters long can be spun, and the thickness of short large special bamboo joint yarns is magnified from 1.2 times to 5-6 times. According to the irregular raindrop yarn production method, the shortcoming that the bamboo joint yarns with the bamboo joints shorter than 2 cm cannot be produced in the prior art is overcome; the production blank of the irregular bamboo joint yarns with large-time joint length is filled; and the fabric woven by the irregular raindrop bamboo joint yarns enriches the requirement of the market on the variety of textile fabrics.
Description
Technical field
The present invention relates to the weaving technology field of knit fabric and decorative fabric, the particularly spinninging technical field of irregular raindrop yarn.
Background technology
A kind of in the raindrop yarn ring, bunchy yarn fabrics is a family of rich and varied textile product kingdom, the characteristics of bunchy yarn fabrics are that ring random distribution on cloth cover has rule or irregular ripple, tangible concave-convex sense is arranged, stereovision, be widely used in look and knit, cowboy's clothes and drapery fabric.
At present, ring spinning frame and revolving cup frame can both be produced slub yarn.Utilize mechanical device, electric clutch, frequency converter, stepper motor, servomotor and PVC ring control controller to come moment to cause and become the drafting multiple of spinning machine or cause the feed quantity that becomes in the unit interval, thereby reach the effect that produces ring.
But no matter adopting the RING SPINNING ring still is that revolving cup spins ring, all can not spin the long or pitch of joint with any method and is shorter than 2cm raindrop slub yarn.
Summary of the invention
The present invention seeks to propose a kind of production method that the long or pitch of joint is shorter than the irregular raindrop yarn of 2cm of producing.
The present invention adopts cotton textiles or polyester-cotton blend to mix raw material, forms by opening picking, comb and parallel cotton fibers prior to spinning, drafting, rove, spun yarn and winding procedure, it is characterized in that:
During described opening picking, the relative humidity in workshop is 70%, cotton rolling quantity 450g/m, hired roughneck's rotating speed 800r/mm, feeding roller 12r/min, rotation speed of the fan: 1300r/min;
During described comb and parallel cotton fibers prior to spinning, the relative humidity in workshop is 65%, cylinder rotating speed 330r/mm, thorn rod rotating speed 800r/mm, the import 8.6mm that spaces at the bottom of the little leakage, the outlet 0.5mm that spaces, cylinder to spacing of cover plate is respectively 0.47 mm, 0.40 mm, 0.38 mm, 0.40mm, cylinder to suitable for reading the spacing of upper cover plate is 0.47mm, the upper cover plate position is mentioned the highest, with the total linters rate control of carding step in 3.5%;
During described drafting, the relative humidity in workshop is 68%, roller gauge 11mm*21mm, and ripe dry weight 21.5g/5m, bell-mouthed diameter are 38mm, sliver exporting speed 250m/min;
During described rove, the relative humidity in workshop is 65%, and rove is done quantitative 6g/10m, roving twist factor 130, roller gauge I * II * III=12 mm *, 26 mm *, 35 mm, middle district collector opening 12mm, proparea collector opening 8mm, ingot speed 650r/min;
During described spun yarn, the relative humidity in workshop is 65%, roller gauge 19 mm * 36mm, twist multiplier 450～480, ingot speed＜13000r/min;
During described winder, the relative humidity in workshop is 70%, closes N, S passage, DL*LL=1.80*50 cm ,-D*-L=-60%*50cm.
The present invention adopts in the bold breakthrough conventional spinning process, require the process thought of fiber high conformity as far as possible, but reverse thinking theory, utilize the long and short fiber blending, long and short fiber is slow speed fiber and floating fiber influence or the normal drawing-off of obstruction faster fibres in drawing-off, simultaneously the accumulative total of slow speed fiber and floating fiber itself is piled up, and form irregular raindrop ring principle; Long fiber plays the skeleton link effect, increases yarn strength, and staple fibre forms the style ring.Adopt the inventive method can spin slub length have only several millimeters long slub yarn, and doubly slightly from 1.2 times big to the big special slub yarn of 5～6 times weak point.
The present invention has overcome prior art can not produce the defective that is shorter than the 2cm slub yarn, has filled up the production blank of the long random slub yarn of big multiple joint.The fabric that is made into this irregular raindrop slub yarn enriches market to the requirement of weaving face fabric diversification, has satisfied the consumer psychology of consumer to fabric " strange, new, spy ", is a class that has development prospect in numerous weaving new products.
When the present invention adopts textile raw material, at opening and cleaning step, with the ratio of 35 long-staple cotton/65 cotton noils the cotton noils of 3 grades of Xinjiang Long staple cotton with 3.18 grades mixed; The fibre length of described Xinjiang Long staple cotton is 35mm, and maturity 1.66, fibre fineness are 1.93dtex; The fibre length of described cotton noils is 28.6mm, and short fiber content is less than 16.5%.
When the present invention adopts polyester cotton blending, when opening picking, be that 1.56dtex, length are that the terylene of 38mm mixes with 3.18 grades cotton noils with the ratio of washing 30/ cotton 70 with fibre fineness; The fibre length of described cotton noils is 28.6mm, and short fiber content is less than 16.5%.
The specific embodiment
1, raw material rate of charge
(1) cotton textiles spin:
