Description
Technical Field
The invention belongs to the field of textile manufacturing, and particularly relates to a waterproof fabric and a preparation process thereof.
Background
The waterproof fabric has wide application range and can be used for manufacturing work clothes, fire-fighting clothes, casual clothes, windcheaters, outdoor tents and the like. The waterproof breathable fabric has the main functions of: waterproof, moisture permeable, breathable, insulating, windproof and warm-keeping. In terms of manufacturing process, the technical requirements of the waterproof breathable fabric are much higher than that of the common waterproof fabric; meanwhile, from the quality, the waterproof breathable fabric also has the functional characteristics which are not possessed by other waterproof fabrics. The waterproof breathable fabric has the advantages that the air tightness and the water tightness of the fabric are enhanced, and meanwhile, the unique vapor permeability of the waterproof breathable fabric enables water vapor inside the structure to be rapidly discharged, so that mold breeding of the structure is avoided, the human body is kept dry and comfortable all the time, the problems of ventilation, wind prevention, water prevention, warm keeping and the like are perfectly solved, and the waterproof breathable fabric is a novel healthy and environment-friendly fabric. The real waterproof fabric is greatly limited in application range by multiple requirements, can withstand water seepage pressure even in a humid climate environment for a long time, and is water-proof. For example, the shoes can not be soaked in water when walking outdoors with wind and rain for a long time and kneeling or sitting on a damp ground. The moisture permeability and the waterproof performance of the waterproof fabric on the market are not good enough at present, and the requirements of consumers are difficult to meet.
Disclosure of Invention
In order to solve the technical defects, the invention provides a waterproof fabric and a preparation process thereof.
In order to realize the purpose, the technical scheme of the invention is as follows:
the waterproof fabric comprises an outer layer, a middle layer and an inner layer, and is characterized by comprising tissues: the outer layer comprises first warp yarns and first weft yarns which are interwoven, the inner layer comprises second warp yarns and second weft yarns which are interwoven, and the middle layer comprises third weft yarns, fourth weft yarns and fifth weft yarns which are interwoven with the first warp yarns and the second warp yarns; the first warp yarn comprises a ground warp and a bubble warp, the sum of the coverage coefficients of the yarns of the outer layer is more than 2600, and the yarns in the fabric are all high-twist artificial fibers.
Preferably, the waterproof fabric is high-density woven.
Preferably, the ratio of the manufacturing shrinkage of the ground warp to the manufacturing shrinkage of the blister warp is 0.85-0.9: 1.
Preferably, the foam comprises a water-repellent resin.
The preparation process of the waterproof fabric is characterized by comprising the following steps of:
warping → twisting → slashing → drafting and denting → weaving → dyeing → washing → overflow arrangement → overfeeding soft shaping → air current soft arrangement → waterproof fabric; the fabric is woven by a high-density weft knitting machine according to the tissue in the tissue structure of the waterproof fabric, and the ground warp and the workshop humidity are 55-60%.
The invention has the beneficial effects that:
(1) the invention adopts the following steps: the waterproof fabric comprises an outer layer formed by interweaving a ground warp and a bubble warp with a first warp and a first weft, an inner layer formed by interweaving a second warp and a second weft, and an intermediate layer formed by interweaving a third weft, a fourth weft and a fifth weft with the first weft and the second warp, wherein the intermediate layer is formed by interweaving the third weft, the fourth weft and the fifth weft with the first warp and the second weft, and the waterproof material is woven in a high-density mode.
(2) The warp is stained with waterproof resin, so that the diameter of the warp is enlarged, the surface of the warp becomes light, the weft yarns which are woven together form small convex bodies, and the small convex bodies have a certain shrinkage ratio with the ground warp, so that the small convex bodies are smaller than the surface tension of water, rainwater on the outer layer is more difficult to enter the interior of the fabric, sweat formed by condensation of sweat on the inner layer is easier to remove, and the waterproof and moisture-permeable performance is improved.
(3) The fabric can be woven by a high-density weft knitting machine, the after-finishing process flow is short, and the fabric has the characteristic of simple preparation process.
Detailed Description

The waterproof fabric is high-density woven.
The manufacturing shrinkage ratio of ground warp to the foam warp is 0.85: 1.
The bubble warp contains a water-repellent resin.
The preparation process of the waterproof fabric is characterized by comprising the following steps of:
warping → twisting → slashing → drafting and denting → weaving → dyeing → washing → overflow arrangement → overfeeding soft shaping → air current soft arrangement → waterproof fabric; the fabric is woven by a high-density weft knitting machine according to the structure of claim 1, and the workshop humidity is 55-60%.
The waterproof performance of the waterproof fabric is tested by the method recorded in AATCC-22-2017. Spraying method: the water temperature is 27 ℃; washing procedure: and (3) washing at 27 ℃, performing conventional washing, hanging and airing, and washing with water for 20 times. The moisture permeability is determined by GB/T12704-2009 moisture permeability cup method for measuring the moisture permeability of fabrics. The performance test results of the waterproof fabric are as follows: [ Water repellency/score 90 after washing 20 times, moisture permeability 14321/g/m after 24 hours2。
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the technical solutions and the inventive concepts thereof according to the present invention should be equivalent or changed within the scope of the present invention.
