Description

Technical Field

[0001] This invention relates to the field of textile fabric processing technology, and in particular to an integrated process for liquid flow scouring and silicone finishing of modal-polyester blended interlining fabrics. Background Technology

[0002] In recent years, natural fiber fabrics have become mainstream in the market due to their health and environmental protection characteristics. The matching garment linings need to simultaneously meet the comfort and texture of natural fibers and the practical performance of synthetic fibers, such as the softness of cotton, the luster of silk, and the smoothness of linen, as well as high strength and abrasion resistance. Currently, blended fusible interlinings, as the mainstream product, have the following technical defects:

[0003] Insufficient rubbing fastness: Among the existing blended interlinings, the wet rubbing fastness of polyester-cotton blended interlining is only grade 3-4 and the dry rubbing fastness is grade 3; the wet rubbing fastness of bamboo-polyester blended interlining is only grade 3-4 and the dry rubbing fastness is grade 3; the wet rubbing fastness of polyester / viscose blended interlining is only grade 2-3 and the dry rubbing fastness is grade 2. During the wearing of clothing, pilling and color fading are likely to occur, affecting the appearance and durability.

[0004] Poor dimensional stability: Most blended interlinings have a heat shrinkage rate of up to 4% and a water washing shrinkage rate of up to 3%. They are prone to deformation and discoloration during the hot rolling bonding process, resulting in uneven bonding between the fabric and the interlining and reducing the quality of the garment.

[0005] The process parameters are difficult to coordinate: In the existing refining process, if the caustic soda concentration is below 1.0 g / L, the desizing is incomplete, and if it is above 5.0 g / L, the base fabric will become brittle, and the tear strength will drop to 20-28 CN. In the finishing process, if the softener concentration is below 1.0 g / L, the hand feel will be stiff, and if it is above 5.0 g / L, it will hinder the coating adhesion and the peel strength will drop to 200-300 CN / inch. The conflicting parameters lead to unstable product performance.

[0006] Therefore, this invention proposes an integrated process for liquid flow scouring and silicone finishing of modal-polyester blended interlining fabric to solve the problems existing in the prior art. Summary of the Invention

[0007] To address the aforementioned issues, this invention proposes an integrated liquid-flow scouring and silicone finishing process for modal-polyester blended interlinings. Modal-polyester blended interlinings produced using this integrated process combine the softness and luster of natural fibers with the durability of synthetic fibers. Their rubbing strength is superior to other blended interlinings such as polyester-cotton and bamboo-polyester blends, exhibiting more outstanding dimensional stability and exhibiting less deformation or discoloration during high-temperature bonding.

[0008] To achieve the objectives of this invention, the invention is implemented through the following technical solution: an integrated process for liquid flow scouring and silicone finishing of modal-polyester blended interlining fabric, comprising the following steps:

[0009] S1: Liquid scouring treatment, in which modal-polyester blended base fabric is placed in a scouring liquid containing caustic soda, bath softener and anti-pilling agent, and then scouring, cooling, washing, opening and drying are performed to obtain scouring base fabric;

[0010] S2: Organosilicon finishing treatment, the refined base fabric is impregnated with a finishing solution containing an amino-hydroxyl-modified organosilicon softener, and then dried and shaped to obtain the finished base fabric;

[0011] S3: Coating process, the base fabric is coated with resin through a single-point or double-point coating process to obtain modal-polyester blended adhesive interlining.

[0012] A further improvement is that, in S1, the blending ratio of the selected modal-polyester blended base fabric is 60:40-80:20.

[0013] A further improvement is made in S1, where, based on the volume of water in the liquid cylinder, the concentration of caustic soda in the refining solution is 1.0-5.0 g / L, the concentration of softener in the bath is 0.5-2.0 g / L, and the concentration of anti-pilling agent is 0.3-1.0 g / L.

[0014] A further improvement is made in S1, where the refining liquid is first heated to 60-80°C, then added to the base fabric and circulated, and then heated to 80-110°C for refining for 1-4 hours, and then discharged and naturally cooled to 70°C.

[0015] A further improvement is that, in step S1, the drying temperature is controlled at 90-120℃ and the drying time is 5-10 minutes.

[0016] A further improvement is made in that: the parameters of S1 are optimized using a tear strength prediction algorithm, the algorithm being as follows:

[0017] T=k1×C+k2×T1+k3×t-k4×C0+b

[0018] Wherein, T: tear strength (unit: CN); C: caustic soda concentration (unit: g / L, 1.0≤C≤5.0); T1: refining temperature (unit: ℃, 80≤T1≤110); t: refining time (unit: h, 1≤t≤4); C0: softener concentration in the bath (unit: g / L, 0.5≤C0≤2.0); k1: caustic soda concentration coefficient (value 1.2-1.5, the gain coefficient of increasing concentration on tear strength); k2: temperature coefficient (value 0.3-0.5, the gain coefficient of increasing temperature on tear strength); k3: time coefficient (value 0.8-1.0, the gain coefficient of prolonged time on tear strength); k4: softener inhibition coefficient (value 0.5-0.7, the weakening coefficient of excessive softener on tear strength); b: reference constant (value 20-25, the basic tear strength without parameter influence).

[0019] A further improvement is that, in step S2, the concentration of amino-hydroxyl-modified organosilicon softener in the finishing solution is 1.0-5.0 g / L, based on the volume of water in the liquid tank.

[0020] Further improvements are made in the following aspects: In S2, the padding residue rate is 70%-80%, the drying and setting temperature is 100-200℃, and the base fabric running speed is 25-35m / min.

[0021] A further improvement is that, in S3, the resin is one or more of the following: polyamide, polyethylene, copolyamide, polyester, and polyvinyl alcohol.

[0022] A further improvement is that, in S3, the temperature of the adhesive roller for coating processing is 160-190℃, and the bonding pressure is 0.3-0.5MPa.

[0023] The beneficial effects of this invention are as follows:

[0024] 1. The modal-polyester blended interlining produced by this invention combines the softness and luster of natural fibers with the durability of synthetic fibers in terms of core performance. Its rubbing fastness is superior to other blended interlinings such as polyester-cotton and bamboo-polyester, and its dimensional stability is more outstanding. It is not easy to deform or change color when bonded at high temperature. At the same time, it maintains good tear strength and peel performance, which can effectively improve the overall quality and wearing experience of clothing and meet the requirements of high-end clothing for interlining.

[0025] 2. This invention solves the technical problems in traditional blended interlining processing, such as incomplete desizing and base fabric embrittlement, as well as the contradiction between hand feel optimization and coating adhesion, by precisely coordinating the liquid flow refining and silicone finishing processes. By strictly controlling the concentration range of caustic soda and silicone softener, combined with detailed designs such as step-by-step temperature control and cyclic processing, the various processes are organically connected into an integrated process, which not only ensures the cleanliness and fluffiness of the base fabric, but also provides a suitable surface state for subsequent coating processing, significantly improving production stability and efficiency.

[0026] 3. This invention introduces a parameter optimization algorithm, which quantifies the correlation between key indicators and process parameters, providing a precise basis for industrial production control, avoiding performance fluctuations caused by experience-based operations, adapting the process to different blending ratios and coating methods, and having wide applicability. It can not only stably produce high-quality products, but also reduce production costs. Attached Figure Description

[0028] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0029] Example 1

[0030] according to Figure 1 As shown, this embodiment proposes an integrated liquid flow scouring and silicone finishing process for modal-polyester blended interlining fabric: Modal-polyester 70:30 blended interlining fabric - double-dot coating process.

[0031] Materials and Equipment

[0032] Base fabric: Modal-polyester blended base fabric (blending ratio 70:30, warp and weft density 280 threads / 10cm × 260 threads / 10cm, weight 120g / m²) 2 );

[0033] Chemicals: Caustic soda (industrial grade, 96% purity), bath softener (model SF-802, anionic, 30% solid content), anti-pilling agent (model AQ-101, nonionic, 25% solid content), amino-hydroxy modified silicone softener (model SG-505, cationic, 40% solid content), polyamide resin (model PA-66, melting point 180℃, particle size 50μm);

[0034] Equipment: LMAO-100 liquid refining mill (liquid cylinder capacity 2000L, circulating pump power 5.5kW), MH581 finishing machine (liquid tank capacity 1000L, roll diameter 300mm), GD-200 double-dot coating machine (adhesive roll diameter 500mm, heating power 15kW).

[0035] Process steps

[0036] Fluid refining process:

[0037] Preparation of refining solution: In the 2000L liquid tank of the LMAO-100 type liquid flow refining machine, add 1800L of deionized water, and then add 6.0kg of caustic soda (concentration 3.0g / L, 1800L×3.0g / L=5400g, the actual amount added is 6.0kg to compensate for loss), 1.8kg of bath softener SF-802 (concentration 1.0g / L), and 0.9kg of anti-pilling agent AQ-101 (concentration 0.5g / L) in sequence, and stir for 10 minutes until completely dissolved.

[0038] Heating and feeding: Start the heating system and heat the scouring liquid to 70°C at a rate of 2°C / min. Add 200m of base fabric (roll diameter 400mm), close the feed inlet, and turn on the circulation pump (speed 30r / min) to make the base fabric and scouring liquid circulate in the liquid cylinder (complete one full cylinder circulation every 3 minutes).

[0039] Scouring and Cooling: After 30 minutes, heat to 95°C at a rate of 1°C / min and maintain this temperature for scouring for 2 hours (during which samples are taken every 30 minutes to observe the residual slurry on the base fabric surface; the standard is met when the residual slurry rate is <0.5%). After scouring, turn off the heating and open the drain valve (flow rate 200L / min) to drain the scouring liquid. Allow it to cool naturally to 70°C (takes about 40 minutes; monitor the temperature inside the liquid tank in real time to avoid forced cooling).

[0040] Washing and drying: Transfer the base fabric to a washing tank (water temperature 60℃, flow rate 500L / h), wash 3 times until pH=7 (tested with precision pH test paper); after being flattened by a spreading machine (model KM-300, spreading width 160cm), send it into a dryer (model HG-120, conveyor belt speed 15m / min), and dry at 100℃ for 8 minutes (after drying, the moisture regain of the base fabric is controlled at 6%±0.5%, tested with a moisture regain tester).

[0041] Organosilicon finishing treatment

[0042] Preparation of finishing solution: Add 800L of deionized water to the 1000L liquid tank of the MH581 finishing machine, add 2.4kg of amino-hydroxy modified silicone softener SG-505 (concentration 3.0g / L, 800L×3.0g / L=2400g), and stir for 5 minutes until uniform (use an NDJ-1 viscometer to measure the viscosity and control it at 20±2mPa·s).

[0043] Padding and Setting: The scouring base fabric is fed into the liquid bath at a speed of 20 m / min and padded with the finishing liquid by double rollers (pressure 0.3 MPa). The padding rate is controlled at 75% (detected by weighing: take 100 cm). 2 The base fabric weighs 12g before impregnation and 20.5g after impregnation. The roll allowance is (20.5-12) / 12×100%=70.8%. The roll pressure is finely adjusted to 0.32MPa, and the roll allowance reaches 75%. The fabric then enters a drying and setting machine (15m long) and is dried and set at 150℃ (the oven is divided into 3 temperature control sections: 120℃ at the inlet, 150℃ in the middle, and 130℃ at the outlet). The base fabric runs at a speed of 30m / min (the motor speed is controlled by a frequency converter to ensure that each meter of base fabric stays in the oven for 30 seconds).

[0044] Coating process

[0045] Resin preparation: Preheat polyamide resin PA-66 in an 80℃ oven for 2 hours, add it to a hopper (capacity 50L), and keep the hopper at 60℃ to prevent clumping;
