Description
Technical field
The present invention relates to textile technology field, particularly relate to a kind of abrasion-resistant yarn wire terminal and preparation method thereof.
Background technology
Ring spinner institute yarn must pass through winding procedure, one of reason is that the obvious fault on yarn is removed also to joint again, therefore former two is therefore the cop of low capacity to be become to the cylinder yarn of large package by joint, is conducive to follow-up High-efficient Production and goes out the high-quality fabric.On bobbin winder, widely used Yarn connecting device has two kinds of forms now, the first is that gas is twisted with the fingers knot, the second is the afterturn knot, wherein gas sth. made by twisting knot is that the yarn that by compressed air stream, will need the yarn of two parts yarn of joint mutually to be wrapped in the other side is done above, and the afterturn knot is that the yarn that by a pair of afterturn dish, will need the yarn of two parts yarn of joint to be wrapped in the other side is done.
No matter be that gas is twisted with the fingers knot or afterturn knot, be difficult to the difference that judges that blank area and yarn are dry by naked eyes, due to the yarn section long enough of relevant winding, the brute force of blank area can reach more than 90% of normal yarn dry strength simultaneously.Therefore require can meet fully the requirement of rear operation to Yarn connecting according to routine.
But find in actual application, contain and using the yarn of top connection during as warp thread, very easily, because warp end break causes shutting down, have a strong impact on the raising of loom efficiency.According to each hundred yards length of weaving cotton cloth of statistics, the piece-ups on warp thread surpass 400, so the rub proofness of Yarn connecting greatly affects the warp end break situation of loom.Main cause is that warp thread can be subject to the active force aspect several in weaving process, and first active force is the tension force applied by loom, and this power makes warp thread in tensioning state, is conducive to form the required space of picking; Second power is the frictional force along yarn, and this power derives from the heald frame harness eye up/down edge on the warp thread that causes and menopause tablet or warp thread and heald that moves up and down and repeatedly rubs along yarn direction; The 3rd power is with yarn, to have the frictional force of certain angle, this power to derive from the mutually violent friction of adjacent yarn in the middle formation that moves up and down of heald frame; The 4th power be in beating up the process process reed to yarn violent frictional force.If therefore in weaving process, only there is first power, existing joint design can meet the demands fully, but owing to also having other three power to exist, existing joint style has been difficult to meet the demands, reason is that existing joint style is the yarn end Filament-wound Machine in the yam surface of joint with it, be not subject to effective gripping, and between yam surface embrace and power extremely a little less than, at skin-friction force particularly along under the frictional force effect of yarn direction, docile is very easy to move along yarn in the end fiber of yam surface, thereby significantly reduce embracing and length of Yarn connecting place joint fiber, effect yarn under working joint in tension force or other power disintegrates and causes yarn breakage rapidly.Special needs to be pointed out is, along with the increase of product thread count or the raising of loom speed, between yarn or the frictional force between yarn and loom member significantly increase, the joint breaking probability caused thus also significantly increases.
Therefore, develop a kind of wear-resisting Yarn connecting and preparation method thereof, be not only and meet the requirement of high-grade fabric to the Yarn connecting outward appearance, and be can resist the friction repeatedly between yarn and yarn or yarn and loom member in weaving process fully as warp thread, be one of this area subject matter urgently to be resolved hurrily.
