Abstract
The invention provides a method for reducing twist contraction knots of all-cotton over-twisted yarns. The all-cotton over-twisted yarns are made into cheese yarns first by performing low temperatureset twist on over-twisted cops in an ageing room, and then greatly reduce the phenomena of twist contraction knots by performing high temperature heat-humidity set twist on the cheese yarns in a saucepan. The all-cotton over-twisted yarns produced by the method meet the requirements on the twist contraction knots of all-cotton over-twisted yarns by customers, and the effect is superior to that ofthe all-cotton over-twisted yarns only treated by performing the high temperature heat-humidity set twist on the cheese yarns in the saucepan.
Description
Technical field
The present invention relates to a kind of method that reduces twist contraction knots of all-cotton over-twisted yarns.
Background technology
Because people more and more advocate natural, environmental protection, product comfortable, attractive in appearance, textile goods are subjected to consumer's favor always, and the product that the cotton tight twist yarn is made has met the theory that people pursue.Because strengthened the percentage of twist shrinkage of yarn during the twisting of cotton tight twist yarn, make fabric that tangible crape sense be arranged, feel is refreshing, and the sensation that is similar to gunny products is arranged, and is comfortable and easy to wear.
In the spinning twisting process, fiber form is distorted in the yarn, this twisted state that can keep fiber is to a certain extent tangled in obvolvent between the fiber, further increase along with the twist, this twisted state more and more difficulty is kept, so produce at torsion of fibers under the effect of internal stress, yarn has the trend of untwisting, yarn is lax untwisting under the state of two ends gripping, will produce twist contraction kink phenomenon, this phenomenon will cause the cloth noodles do to worsen, influence attractive in appearance, so the tight twist yarn twist is set twist.At present, the method for tight twist yarn twist dead twist is: directly the tube yarn is put into steamer and carried out the wet dead twist of elevated temperature heat.
The defective of said method is, makes in the process of a yarn at cop, just produced the twist contraction kink, and the tube yarn also is difficult to be eliminated through the wet dead twist of steamer elevated temperature heat again.
Summary of the invention
The purpose of this invention is to provide a kind of method that reduces twist contraction knots of all-cotton over-twisted yarns,, satisfy client's demand to overcome the above-mentioned defective that prior art exists.
The present invention is before the heavy twist cop is made a yarn and put into steamer and carry out the wet dead twist of elevated temperature heat, earlier the heavy twist cop being put into temperature is 50 ℃, relative humidity is to hang down warm and humid dead twist in 80～90% the dewing room that steam pipe is housed, its principle is to set twist by the steam internal stress of fiber that relaxes in the yarn, make cop when making a tin yarn, particularly the twist contraction kink phenomenon that causes owing to joint obviously reduces.
The specific embodiment
Embodiment 1
Earlier be that to put into temperature be 50 ℃ for 600 cop with twist factor, relative humidity is to hang down warm and humid dead twist in 80～90% the dewing room that steam pipe is housed, take out after 24 hours, make a yarn, advance steamer again and carry out the wet dead twist of elevated temperature heat, 60 minutes time, 90 ℃ of temperature, temperature retention time is to take out after 99 minutes, and balance was packed after 24 hours.
To be 600 cotton tight twist yarn through the twist factor of above-mentioned twice dead twist process, and be made into fabric, its cloth cover twist contraction kink number be less than like product greatly, obtains unanimously praising of user.
Claims (1)
1. a method that reduces twist contraction knots of all-cotton over-twisted yarns is characterized in that, has reduced the twist contraction kink phenomenon of cotton tight twist yarn, this twist contraction kink mainly since cop produce when making a tin yarn.
The heavy twist cop is put into 50 ℃ of temperature, hang down warm and humid dead twist in the dewing room that steam pipe is housed of relative humidity 80～90%, take out after 24 hours, make a yarn, put into steamer again and carry out the wet dead twist of elevated temperature heat, 60 minutes time, 90 ℃ of temperature, temperature retention time are taken out packing after 99 minutes.
To pass through the low warm and humid dead twist in cop dewing room, through the yarn of the wet dead twist of tube yarn steamer elevated temperature heat, be made into fabric again, facts have proved that twist contraction kink phenomenon obviously reduces.
