Device and method for preparing polyurethane-free elastic lace

Abstract

The invention relates to the technical field of lace preparation, and discloses a device for preparing a polyurethane-free elastic lace. The device comprises a rack, creels, a first pan head, a second pan head, a main motor, a cloth roller and an electric box; the creels are symmetrically and fixedly arranged at the top of the rack; the first pan head is installed on the left side of the rack; the second pan head is installed on the right side of the rack; a tension piece support is installed at the bottom of the rack; a tension compensator is arranged at the tail portion of the tension piece support through a first yarn guide tension rod; a yarn splitting comb is arranged below the tension piece support; and the main motor and the cloth roller are both arranged below the yarn splitting comb. According to the device and method for preparing the polyurethane-free elastic lace, the weight of a polyurethane raw material and a fabric is omitted, the use of one guide bar is reduced on equipment, excessive guide bars can be used as additional jacquards, meanwhile, in post-treatment, the treatment of polyurethane can be omitted through the polyurethane-free method, and the production cost of a product can be further reduced.

Description

technical field [0001] The invention relates to the technical field of lace preparation, in particular to a preparation device and method for spandex-free elastic lace. Background technique [0002] Along with the raising of people's living standard, the application field of lace is more and more extensive, because elastic lace has certain elasticity, it can meet people's requirements for wearing in wearing. At the same time, people's requirements for wearing similar to lace are also constantly improving, and lace fabrics need to meet people's requirements for characteristics such as lightness, plasticity, and comfort. [0003] At present, most of the elastic laces on the market achieve a certain degree of elasticity by adding spandex to the weaving. The production technology of this method is relatively mature, but this method requires additional weaving bars on the weaving equipment. Realize that spandex that only realizes elasticity also increases the weight of lace fabr...

[0003] At present, most of the elastic laces on the market achieve a certain degree of elasticity by adding spandex to the weaving. The production technology of this method is relatively mature, but this method requires additional weaving bars on the weaving equipment. Realize that spandex that only realizes elasticity also increases the weight of lace fabrics. At the same time, in daily use, the method of using spandex to achieve elasticity also has many shortcomings, such as spandex flying out, spandex rolling out, spandex failure, yellowing , separation and other difficult problems
