New Spandex Yarn
Core Slub Spandex cloth made of rough, soft, thick, gives a clear novelty. Bamboo knot spandex core yarn spinning machine in the cotton to spandex core-spun yarn and spun slub yarn method of combining the two kinds of the spin system of a new species. Spandex Core Yarn with different models of the spinning frame in almost the same, spandex yarn guide wire through the roll, roll into the first skin.
In accordance with the situation Slub Slub was divided into regular and irregular two, non-random distribution laws of bamboo present, there is no fixed length and pitch. Is divided into two kinds of regular, sub-section length, pitch fixed and regular non-isometric bamboo. In this case there is a pattern used in length, the pitch is not the same form. The device is a programmable logic controller PC, you can enter the 122 set of parameters and laws of long cycle and the effect in the cloth is no law of effect.
In order to ensure yarn strength, you can start from two aspects, one is to enhance the yarn twist, yarn higher than the normal 40% to 60%, followed by the distribution of cotton yarn than other ordinary-zhi high-grade 2 or more; textiles base Spandex slub yarn for 19.7TEX should be properly blending over a certain proportion of long-staple cotton. After the roller in the instant acceleration of the inevitable unwinding of the formation of roving tension mutation, so roving twist factor configured to withstand the tension of the mutation, the first principle of continuous roving, one of the appropriate take along larger than conventional varieties, on the other roving twist coefficient is too large, the spun yarn in order to not appear on the “hard head” principle, where the “hard head”, the only soft flexible leather roll, or gauge the appropriate enlarged area, if necessary, things can be more appropriate pre-amplification Area roller gauge, but do not adopt measures to increase pressure on leather roller, otherwise affect the electromagnetic clutch life.
The species selected G08-inch steel wire ring, gas ring patterns have been well controlled, relatively clean gauze. After the roller drafting part of the axis of the “key” to periodic inspection, replacement, can not have space, otherwise it would cause slewing Leighton, thus affecting the quality of yarn. After the roller due to the instantaneous acceleration, shear force on the key lot, generally with around two months to be replaced. Strengthen the spindle drive part of the examination, can not have a weak twist generated, if there is a weak twist yarn produced in the fabric surface can range from cloth produced uneven, there are color files, re-skinning the formation of spandex. The choice of spandex core-spun yarn guide wire wheel requirements can be adjusted horizontally alone in order to ensure that the spandex surrounded by cotton fibers to prevent the exposed core yarn produced.
In operation, when there are yarn breakage, we should no longer be with the original cop joints, while the other head regeneration. Such as connectors, in the joint Department has a spandex yarn wrapped around the outside, the length of time due to cut the joints rather than the length of time, like, if this can not be broken wires in winding, when removed, will affect the quality of cloth. In the yarn density test, the pre-tension larger than the ordinary yarn. Test Pre-tension when the yarn density, the condition is “to stretch out but can not stretch the yarn.” General yarn is half the number of gut, but because it is the existence of spandex slub elasticity, such as the gut is still half of the number of tension, can not make the yarn straight, so the test showed that the density of the yarn is too large, using Canadian double the pre-tension tested contrast, it can not achieve full extension to make the yarn, but it is closer, and on this point have not yet present, the industry lied to the corresponding provisions. Although slub yarn, but in the spinning process will produce some yarn of bamboo, it should be winding electronic yarn clearer when the top of thick bamboo yarn from social defect removal, the electronic yarn clearer set Bureau of specific varieties of value should be determined individually, and then look at the effect of technology on the train.
