Glass fiber produced by using the sizing agent has high convergence, yarn has moderate stiffness and high flight performance, and the requirement for the physical performance of yarn of warps and wefts is met; and meanwhile, jetting is performed during beating-up, so that fiber opening is easy, energy consumption of beating-up and fiber opening can be effectively saved, the air permeability of grey cloth can be lowered, the production cost is lowered, and a maximum economic benefit is created.
Description
Technical field
The present invention relates to the glass fiber yarn technical field, especially a kind for the treatment of compound of electronics yarn for weaving purpose, and preparation method thereof.
Background technology
The glass fibre spun yarn can be divided into electronics yarn for weaving purpose and industrial yarn substantially by its purposes, and the electronics yarn for weaving purpose has the most large purposes in glass fiber yarn, especially model is that the G75 yarn has occupied a large sum of rivers and mountains in existing market, and estimates that the market structure does not have big change at short notice.
Electronics is weaved and is used electric yarn, and two kinds of warp thread and weft yarns are arranged; Warp thread requires yarn that certain stiffness is arranged, and wear resistance is good; Weft yarn then needs yarn softer, flat, and convergency again can not be too poor simultaneously, is beneficial to and weaves, and the cloth cover filoplume is few.This just causes G75 roving sizing agent type commonly used in the market, and dividing has warp thread prescription and weft yarn to fill a prescription two kinds, and in the weaving process of electronics cloth, warp thread need separate with yarn with weft yarn to be produced, manage and sell like this.A large amount of electronic-grade G75 yarns that use through roving sizing agent, convergency is good, the yarn bundle is harder, but air pressure is big when making weft weaving, and air consumption is big, and energy consumption is big, and yarn open fine poor-performing, use the strong modified corn starch of boundling power of larger proportion (the 60% or more than) membrane-forming agent of deciding in the warp thread prescription, the wear resistance that reaches yarn is good, the convergency height; The yarn warp thread convergency when making warp thread that uses weft yarn treating compound formulation types to produce is relatively poor, the yarn bundle is softer, yarn easily produces filoplume during warping, cause fabric defect many, can not use, and requiring at present under the condition of beating up at a high speed, the weft yarn prescription is made weft yarn and also had defective: yarn looses and causes the cloth cover filoplume many.Weft yarn prescription: use about 40% corn and the potato treated starch membrane-forming agent of deciding in the prescription, reach soft yarns.
If exploitation longitude and latitude dual-purpose G75 electronics spun yarn can make the management of weaving mill and cotton mill production management and storehouse simple, and reduce the stock, also reduce the energy consumption of electronics cloth factory, make product in market, have more competitive power.
