Description
Technical Field
The invention relates to the technical field of manufacturing of sweaters of textile flat knitting machines, in particular to a process for producing a high-elasticity flat knitting machine product.
Background
Because the sweater clothes have natural elasticity formed by self organization structures, have the characteristics of unique style, rich styles and capability of quickly responding to the market demand, and are popular with enterprises and consumers all the time. However, if the sweater is worn for a long time, the sweater can be shortened, lose elasticity and deform, consumers feel that various methods are thought for restoring the elasticity of the sweater, but the effect is not good, mainly because the use of elastic raw materials is limited due to the particularity of the production mode of the sweater.
As is known, the ready-made clothes have high elasticity and elastic recovery rate mainly depending on elastic fiber materials in the fabric, and the elastic fiber used in the traditional high-elasticity fabric, whether polyurethane fiber (spandex) or polyether ester elastic fiber, can obtain high elasticity and elastic recovery rate and simultaneously can ensure the dimensional stability and the shrinkage rate of the fabric through high-temperature shaping. However, the sweater is formed by directly producing the ready-made clothes cloth pieces on a flat knitting machine by using yarns, sewing the ready-made clothes pieces into ready-made clothes, and then washing and ironing the ready-made clothes. The production of the high-elasticity sweater just lacks the high-temperature shaping process between the cloth piece and the ready-made clothes, so that spandex elastic fibers can not be generally selected when selecting the sweater material, and the requirements of the high-elasticity sweater such as shrinkage, curling, dimensional stability and the like are difficult to ensure.
In the prior art, a method for improving the elasticity by stranding single yarns into high-twist plied yarns by using a method of twisting in the same direction is adopted, but the high-twist sweater has over-hard hand feeling and can cause twisting; the elastic sweater is also produced by using a method of firstly weaving spandex core-spun yarns produced by optimizing the spandex draft ratio and then ironing the garment by a high-temperature die-covering mode, but the dimensional stability and the water shrinkage rate of the whole batch of products are difficult to stabilize during batch production; there is also a method for improving elasticity by plying single yarns with different boiling water shrinkage rates in a non-drafting and non-core-covering mode, but the dyeing problem of mass production is difficult to solve due to the use of polyester filaments needing high-temperature dyeing, and the elasticity and the elastic recovery rate of the finished sweater are also small and far less than the high elasticity of spandex due to the adoption of the non-drafting and non-core-covering mode during spinning, and meanwhile, the polyester product belongs to chemical fibers, cannot be biodegraded and is not beneficial to sustainable development of the environment.
Therefore, how to produce a high-elasticity sweater product with stable shrinkage and without losing elasticity and deformation leads consumers to enjoy the sweater which is more comfortable, easier to manage and more environment-friendly, and becomes a problem to be solved by related personnel in the field.
