Problems solved by technology

[0002] It can be said that polyester imitation cotton products are not uncommon in the market now. They all have a relatively soft and delicate feel of cotton fabrics, and give full play to some advantages of polyester fabrics. For example, polyester fabrics are durable and shape-retaining. Elastic recovery ability, and good light resistance and chemical resistance, make up for some shortcomings of cotton fabrics to a certain extent; there are mainly two technical means to develop its fabrics, one is polyester staple fiber imitation cotton technology, Mainly by cutting polyester filaments into a length similar to cotton, and then imitating cotton-type yarns through the spinning process, endowing the yarns with hairiness similar to cotton threads, the process is long and complicated, and the cost is high; another One technique is to process the polyester filament fabric through fluffing to achieve the surface style similar to cotton fabric, but its hairiness is poor, and the cotton feeling is easily weakened after washing, and the fabrics made by these two techniques are not hygroscopic. poor performance

Embodiment 1

[0016] A cotton-like polyester filament fabric, the cotton-like polyester filament used is 215T / 168 composite yarn, the raw yarn selected during processing: decorative yarn 2 is pre-oriented yarn 133T-144-POY, core yarn 1 It is a fully drawn yarn 75T-24-FDY, the filament length difference between the core yarn and the decorative yarn is 5%, the monofilament fineness of the decorative yarn is 0.8D / F, and the core yarn monofilament fineness is 2.8D / F, pre-oriented The silk accounts for 64% of the weight of the entire cotton-like polyester filament, and the fully drawn yarn accounts for 36% of the weight of the entire cotton-like polyester filament. The core yarn and decorative yarn are fed into the air texturing nozzle (TASLAN) 3, and they are deformed by the action of air flow; then the cotton-like polyester filament 215T / 168 composite yarn is used as the warp yarn, and the weft yarn is 150D elastic yarn. 5 satin patterns on the surface of 2 flying warps, the density of warp and we...

Embodiment 2

[0024] A cotton-like polyester filament twill fabric. The cotton-like polyester filament used is the same as that in Example 1. The warp and weft yarns are all cotton-like polyester filament, the weave is 2 / 2 twill, and the warp and weft density is 170 threads / inch× 56 pieces / inch, the grey fabric is refined → dried → intermediate shaping → continuous alkali weight reduction → dyeing and moisture absorption → resin → finishing and shaping to make a product. The weight of cotton-like polyester filament yarn in the fabric accounts for 100% of the weight of the entire fabric. The product is light in weight, wear-resistant, easy to wash, and has a rich, delicate and soft appearance and feel similar to cotton fabrics and excellent moisture absorption properties.

[0025] Key engineering conditions:

[0026] Weight reduction: the concentration of caustic soda is 35%, the residence time is 10MIN, the weight reduction rate is 16.6%, V cloth=40M / MIN;

[0027] Dyeing: 135℃×35MIN, dosage of ...

Embodiment 3

[0031] First, make cotton-like polyester filaments, and then use cotton-like polyester filaments as at least one of warp and weft to make grey fabrics. The grey fabrics are subjected to post-treatments including continuous alkali weight reduction, dyeing and moisture absorption, finishing and shaping steps. The product is produced; when the cotton-like polyester filament is manufactured, the decorative yarn with the yarn type of pre-oriented yarn and the core yarn with the yarn type of fully drawn yarn are fed into the air deformation nozzle and deformed by the action of airflow; The difference in filament length between the core yarn and the decorative yarn is 2%-10% (example 2%, 6%, 10%), and the core yarn monofilament fineness is 0.5D / F~2.0D / F (example 0.5D / F) , 1D / F, 2.0D / F). Pre-oriented yarns account for 55 to 70% of the weight of the entire cotton-like polyester filament (Example 55%, 65%, 70%), and fully drawn yarns account for 30-45% of the weight of the entire cotton-lik...

Abstract

The invention discloses cotton imitating polyester filament fabrics and its preparation method thereof. At least one yarn of warp yarn and weft yarn for composing the fabrics is cotton imitating polyester filament which is air deformed composite yarn. The production method includes: manufacturing the cotton imitating polyester filament at first; producing grey fabrics with the cotton imitating polyester filament which is at least one of the warp yarn and the weft yarn. Then, a product is obtained after the post treatment on the grey fabrics, including the steps of continuous alkali decrement treatment, drying and moister absorption and finishing setting. The product produced through the invention has the advantages of light weight, wear resistance, washing easiness and rich, fine and soft appearance and handle and perfect moisture absorption performance which are similar to cotton fabrics.

Description

Technical areas: [0001] The invention relates to a textile and a preparation method thereof. Background technique: [0002] It can be said that polyester imitation cotton products are now common in the market. They all have a relatively soft and delicate feel of cotton fabrics, and give full play to some of the advantages of polyester fabrics. For example, polyester fabrics are durable and have good shape retention, and have certain Elastic recovery ability, and good light resistance and chemical resistance, which to a certain extent make up for some shortcomings of cotton fabrics; there are currently two main technical means to develop its fabrics, one is polyester staple fiber imitation cotton technology, Mainly by cutting polyester filament into a length similar to cotton, and then imitating cotton-type yarn through the spinning process, giving the yarn hairiness similar to cotton thread. The process is long and complicated, and the cost is high; another The first techno...
