Sizing technology of environment-friendly size on interwoven fabric

Abstract

The invention discloses a sizing technology of an environment-friendly size on an interwoven fabric. The interwoven fabric is composed of cotton yarn and polyester network yarn. The sizing technology comprises the following steps: step 1, a beam-warping process, wherein the beam-warping length of the polyester network yarn is 1% longer than the beam-warping length of the cotton yarn; step 2, a size mixing process, wherein the cotton yarn is composed of hydrophilic fibers, the polyester network yarn is composed of hydrophobic fibers, and therefore different size mixing technologies are used; step 3, a slashing process, wherein different size tanks, different squeezing roller pressure and different drying drum temperatures are used for the cotton yarn and the polyester network yarn to carry out the slashing process simultaneously, and the moisture regain of the two types of warp yarn is controlled to be in the range of 4.8% to 5.0%; and step 4, a weaving process, wherein the speed of a weaving machine is 665RPM, and the tensile force of the weaving machine is 3,800N. By means of the sizing technology, the weaving efficiency of the weaving machine can reach 90%, the preparation technology is simple, the fabric cover is flat, smooth and good in style, texture is clear, the size used for the sizing process is easily degradable and cannot cause any pollution to the environment, the purpose that no polyvinyl acetate (PVA) is used in the sizing process is achieved, and a novel concept and a novel method are provided for textile enterprises for environment-friendly production.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a sizing process for interwoven fabrics with environmentally friendly sizing materials. Background technique [0002] Currently, PVA and polyester sizes are mainly used in the textile sizing industry. PVA products are petrochemical products with limited natural resources and serious environmental pollution, and are being phased out gradually. Polyester size is a new type of size in recent years, but it is also based on petrochemical products, which seriously pollutes the environment. At present, the cost of polyester size per kilogram is 25-30 yuan per kilogram, which is expensive, resulting in textiles The production cost is high and the price is expensive. Therefore looking for a kind of not only environmental protection, but also cheap product to replace polyester size and PVA has become the target that the personages in the industry pursue at present. [0003] In the past...
