Production method of copper ammonia/viscose/linen cotton fiber blended fabric

Abstract

The invention discloses a production method of a copper ammonia / viscose / linen cotton fiber blended fabric. According to the production method, selected warp and weft materials are as follows in parts by mass: 30-50 parts of copper ammonia fibers, 15-25 parts of linen fibers, 40-90 parts of viscose fibers, 20-40 parts of combed cotton and 8-18 parts of ultrafine fine denier polyester. A step of slashing in the production process comprises the specific steps: (1) mixing size: adding water into a size mixing bucket and raising the temperature of the water to 50 DEG C, adding a pre-dyeing agent, wherein the adding mass of the pre-dyeing agent is 15-18% of that of water, starting a stirrer and adding solid PVA (Polyvinyl Acetate) at the mass ratio of the solid PVA to the water of (1-4) to 80, raising the temperature to 90 DEG C, and stirring and dissolving to prepare slurry; and (2) sizing: sizing by adopting a slashing machine, wherein size in a size tank does not need to be heated. The yarns of the sizing procedure are subjected to sizing by adopting the PVA with the concentration which is not higher than 4%; the sizing rate is low, size skins are not easy to form by a sizing agent and desizing is easy to carry out by post-finishing; and meanwhile, the sizing agent can be stored after being prepared and can be used at any time in future, and does not need to be prepared when being needed, so that the energy and time are saved.

Description

technical field [0001] The invention belongs to the technical field of textiles, in particular to a method for making a cupro / viscose / hemp-cotton fiber blended fabric. Background technique [0002] The traditional yarn sizing process generally uses PVA, starch, acrylic acid and other sizing materials to mix and sizing. The traditional sizing method is to use a mixing tank with an agitator. Amount of water, turn on the agitator and slowly add PVA, starch, acrylic acid and other sizing materials in the prescribed order, heat up to 112°C, cook the pulp for 20 minutes, turn on the agitator at 95°C and keep warm for later use, keep the temperature of the sizing tank at 98°C ; This process consumes a lot of energy, and the sizing rate is relatively high (the sizing rate of the strand variety is 8%, and the sizing rate of the single yarn variety is about 12%). It is difficult to desizing in the finishing process, which affects the final finishing effect of the fabric. [0003] Due...

It is difficult to desizing in the finishing process, which affects the final finishing effect of the fabric.

[0003] Due to the inherent properties of viscose fiber itself: the fiber is relatively fluffy, the single fiber is also relatively brittle, and the weavability is poor. During the spinning process, static electricity is more serious, hairiness is more, fibers are easy to stick, cotton nets are easy to fall, and bell mouths are easy to be blocked, etc., which cannot be applied to daily textiles
